Chapter 1. What does financial advice really cost?

Most people go into fee conversations blind. This chapter gives you enough context to judge whether any adviser, including this one, is fair value.

The key insight

The advice fee is only one of five layers you pay. Most people compare the one they are shown and miss the four they are not.

The three things you are buying

01
The financial plan
Understanding what you want, what you have and what is missing, before any money moves. £2,500–£5,000 typically; £7,000+ where complexity is real.
02
Implementation
Opening accounts, moving money, setting up investments. 0.25%–1.0% of the amount invested. The FCA puts the average total initial charge at 2.4%.
03
Ongoing advice
Reviews, monitoring, adjusting as life changes. FCA average 0.8% a year; NextWealth 2026 says 0.83%, up from 0.77%.

The five layers of cost

An honest pricing conversation accounts for all five, not just the first.

LayerWhat it pays forTypical range
Advice feePlanning, recommendations, ongoing serviceFixed, or 0.5–1.0% a year
Platform feeCustody, administration, reporting0.10–0.45% a year
Investment managementFund selection, buying, selling, risk0.20–0.50% a year
Fund costsOngoing charges of the funds held0.07–0.20% passive
0.50–1.00%+ active
Transaction costsTrading inside those fundsVaries by fund

Most clients investing through an adviser pay between 1.2% and 2.5% of their portfolio a year, all in.

Percentage or fixed? There is a crossover point

Around 70% of UK advisers charge a percentage of assets. The arithmetic cuts both ways.

Portfolio1% a year£6,000 fixed feeOver 20 years
£1,000,000£10,000£6,000£200,000 vs £120,000, so fixed wins
£300,000£3,000£6,000The fixed fee costs twice as much

Percentage charging is generally cheaper below a crossover point and dearer above it. The only way to know which side you are on is to ask for both, in pounds, at your own numbers.

Xentum charges fixed fees. Weigh this section against that interest.

+What makes advice more expensive
  • Complexity. Multiple pensions, a business interest, property, inheritance, or a spouse in a different position.
  • Quality of planning. Modelling and stress-testing takes far longer than a surface review.
  • Depth of ongoing service. Proactive review and coordination beats an annual call.
  • Experience and specialism. Chartered status signals a commitment not every firm makes.
  • Regulatory rigour. Every recommendation documented, evidenced, defensible.
+What keeps the cost down
  • Simpler financial lives genuinely mean less work
  • Fewer moving parts mean lighter reviews
  • Doing your own legwork can reduce adviser time
  • Good systems carry lower overhead
+Why some advisers are more expensive

Some genuinely deliver more. Some carry a brand premium, so you are partly paying for the brand rather than the advice. Some offer complex structures worth paying for only where they solve a problem you actually have.

And some are dearer because of how they charge, not what they deliver. At scale, a percentage of assets can produce fees with little relationship to the work. The counter-argument is equally real: the same model means a £200,000 client pays a tenth of what a £2m client pays for the same process, and that cross-subsidy is part of how smaller clients get advice at all.

+What does not show up in a headline quote
  • Initial charges on top-ups
  • Ad hoc advice fees outside the review cycle
  • Pension transfer exit penalties from the old provider
  • Protection advice charged separately
+Who else is involved, and what they cost

Four distinct roles exist, each with a separate cost.

  • Adviser or planner, working for you. £1,500–£4,000 one-off, then £2,000–£10,000+ a year, or 0.5–1.0%
  • Custodian or platform, holding investments. 0.15–0.40% a year, often capped
  • Investment manager, deciding how money is invested. 0.25–1.0% a year
  • Fund manager, running the fund. 0.05–0.75%, inside the fund price

One company can play more than one role. That is where duplicated charges hide.

What this means for you
Ask every firm for a total cost illustration in pounds, covering all five layers, for year one and each year after. They are required to provide it. If you have not been shown one, ask.
Key takeaway

The mistake is evaluating advice fees in isolation, rather than against the value they are designed to create.

Chapter 2. What level of advice do you actually need?

The right level depends less on how much money you have than on how complex your situation is and how much support you want.

The key insight

Choosing the wrong scope, either too small or too large, costs you either way. The goal is not the cheapest scope or the fullest one. It is the right one.

Two questions worth sitting with: How many moving parts do I have? And how confident do I feel managing them myself?

The four levels

Level 0
Self-directed investing
DIY platforms and robo-advice. Efficient, accessible and low cost, with no personalised advice, no behavioural coaching and nobody helping you decide.
Level 1
Single-issue advice
One decision: should I transfer this pension? Useful in the moment, but it does not consider how that decision affects everything else.
Level 2
Financial advice
Where most traditional advisers operate. Money organised, invested appropriately, reviewed annually, joined up but not fully life-centred.
Level 3
Full financial planning
Starts with your life rather than your investments. All financial planning includes advice; not all financial advice includes planning.
+Level 0: what it can and cannot do

These tools let you open accounts, pick funds directly, select a risk level, and automate saving.

They cannot tell you how to align money with long-term goals, which tax wrappers to prioritise, how to handle pensions, property, business equity or family wealth, or how to adjust during market stress.

For someone starting out that is perfectly adequate. For others it leaves major blind spots.

+Level 1: best for, and limits

Best for very simple needs, occasional one-off input, clarity on a single decision.

Limits: does not address long-term goals, does not consider knock-on effects, no ongoing partnership. The equivalent of calling a gardener to trim one hedge.

+Level 2: typically covers

Retirement planning, investment strategy and risk, basic tax planning, protection needs, an annual review, light-touch cashflow modelling.

Limits: long-term goals and family priorities may not be deeply explored; cashflow modelling may be simplified; behavioural coaching is usually minimal.

+Level 3: typically includes

Goals and values, detailed long-term cashflow modelling, tax strategy, family and intergenerational planning, estate and legacy design, business-owner planning, investment strategy built around the plan, behavioural coaching, and coordination with accountants and solicitors.

Limits: more time and reflection upfront; unnecessary for very simple situations.

What this means for you
Before you contact anyone, count your moving parts: pensions, ISAs, property, business equity, protection and cash. That count, and your own confidence, points at the level. Not your net worth.
A note on online reviews

Reviews affect how firms rank in search, so a firm with many will appear higher. That is a fact about search, not about the advice. Read them for content rather than count. A handful describing situations like yours tells you more than a large number saying the adviser was friendly. Neither score nor volume tells you which scope you would be buying. Ask that directly.

Key takeaway

Complexity and confidence set the level, not the size of your portfolio.

Chapter 3. Which type of advice is right for you?

Something most consumers never hear: no adviser type sits neutrally above both property and investment decisions.

The key insight

Property specialists recommend property. Financial advisers recommend portfolios. The comparison most people actually need has no natural owner, because the incentives on both sides point away from it.

Property against portfolio

CriterionPropertyPortfolio
LiquiditySlow to sell; high transaction costsVery quick; low transaction costs
DiversificationConcentrated unless you hold severalEasily diversified across assets and regions
LeverageStrong mortgage leverage, amplifying returns and riskLimited; controlled risk
Upfront costsHigh: deposit, stamp duty, legal, refurbishmentLow entry threshold
Ongoing costsMaintenance, repairs, insurance, voids, managementLow, predictable fund and platform fees
ControlHigh: you choose property, tenants, improvementsLow: delegated to managers
Time and effortHands-on unless fully managedMinimal once set up
Tax treatmentSome advantages remain; others tightenedStrong long-term advantages via ISAs and pensions
Estate planningHarder to divide; liquidity issues on deathEasy to allocate or transfer

These are structural characteristics, not a verdict. Neither is better.

What each advice type can actually deliver

Advice typeLevel 1Level 2Level 3
DIY investingNoNoNo
Robo-advicePartlyNoNo
Restricted adviceYesYesSometimes
Independent adviceYesYesSometimes

Full financial planning is a scope, not a badge.

Those two sometimes entries are the most important thing here. Independence gives maximum product choice, but many independent advisers are still primarily investment advisers. Equally, some restricted firms deliver excellent full planning within a narrower range.

Mind the gap

If you are considering DIY or robo, know about the behaviour gap, the difference between what a fund returns and what investors actually receive. Morningstar puts it at roughly 1% to 2% a year, caused by buying after markets rise and selling when they fall. Over 20 years, even a 1.5% gap can reduce total wealth by more than 30%. Markets usually work. Staying invested is the hard part.

What this means for you
Ask the label question, independent or restricted, but do not stop there. Ask what the firm’s planning process actually includes. The label tells you about product range; it tells you nothing about scope.
Key takeaway

Ask what a firm’s process delivers, not what its label says.

Chapter 4. Is your financial setup ready for advice?

Your current setup influences both the type of advice you need and how effectively it can be delivered. Some situations are ready. Others need groundwork first.

The key insight

You can be ready for a conversation but not yet ready for advice. Turning up with missing paperwork costs you money in investigative time.

Five things that shape it

1
Complexity
Pensions old and new, ISAs, property, business equity, protection, mortgages, cash across banks, trusts, family commitments. The more moving parts, the more likely you need level two or three.
2
Documentation
Any adviser must know what you hold, where it is, what it costs and what terms apply. Missing paperwork does not prevent advice. It slows it and adds cost.
3
Behaviour and decision-making
How you react to money matters as much as what you hold. People who struggle with emotional decisions benefit most from an ongoing relationship.
4
Property against investments
One of the biggest suitability questions and least addressed. Your comfort with leverage, liquidity and rental risk points to the route.
5
Life circumstances
Retirement, a business sale, an inheritance, divorce, a career change, downsizing. When life changes, complexity follows.

A quick readiness check

Tick the ones that are true today.

What this means for you
Fewer than three ticks? You are ready for a conversation, not yet for advice. Gathering the documents first is the single cheapest thing you can do to improve what you get out of the process, whoever you end up using.
Key takeaway

The cheapest hour you will ever spend on advice is the one before the first meeting.

Chapter 5. What goes into a financial plan

Financial advice is not a single product. It is a combination of components: some essential, some optional, some dependent on your stage of life.

The key insight

Your plan should include only the components that genuinely support your life. Nothing more, and nothing less. If you are paying for something, you should be able to say why.

The three core components

01
Cashflow modelling
Builds a long-term picture from income, spending, assets and goals. Answers will we have enough?, when can I retire? and what if things change? It turns broad worries into testable scenarios.
02
Investment strategy
Not just what you invest in, but why and how: risk level, asset allocation, rebalancing and cost structure, appropriate to your goals and your temperament.
03
Tax planning
Using the system efficiently: ISAs, pensions, venture schemes, capital gains exemptions, dividend allowances, investment bonds, inheritance, business-owner wrappers.

Everything below is situational. Expand only what applies to you.

+Retirement planning

Depends on life stage. Predicting spending needs, drawing income sustainably, choosing between lump sums, flexible drawdown and annuities, managing sequencing risk, minimising tax drag.

+Protection planning

Optional, but it is the base of the pyramid. Everything else sits on top. Life cover, income protection, critical illness, business continuity. Not everyone needs these, but for families reliant on one or two incomes it prevents serious strain.

+Property strategy

Optional, but often essential. Hold or sell, downsize or upsize; buy-to-let viability and leverage; liquidity. Most people’s wealth involves property, yet traditional investment advisers do not sit above both worlds.

+Business-owner planning

Specialist. Exit strategy, remuneration, shareholder arrangements, post-exit structure. Requires close coordination between advisers and accountants.

+Estate and intergenerational planning

Increasingly important with age and complexity. Wills and structure, inheritance tax and gifting, family investment decisions.

+Ongoing review and behavioural support

For many, where the long-term value sits. Keeping you accountable and the plan relevant, maintaining discipline during volatility, adjusting to life changes.

+Additional services

Scenario stress-testing, education sessions for children, family meetings, coordination with accountants and solicitors. Not everyone needs these, but they can improve clarity.

What this means for you
Ask a prospective firm which of these ten you are paying for, and which are excluded. A clear answer is itself a signal.
Key takeaway

A good plan is scoped to your life, not padded to justify a fee and not thinned to hit a price.

Chapter 6. How good advice is delivered

Whichever advice type you choose, good advice follows a structured, transparent process. The depth changes with the scope, but the stages are the same.

The key insight

Use these nine stages as an interview script. Ask a firm to walk you through their process from first meeting to first review, and count how many they can describe without notes.

1
Discovery
Understanding your goals, priorities, concerns and decision-making style, before discussing products or portfolios.
2
Data gathering
Accurate information on pensions, investments, property, protection, income, spending and tax position.
3
Analysis and modelling
Assessing your situation and testing assumptions through modelling and scenario analysis.
4
Strategy design
A coherent, evidence-based plan aligned to your objectives and constraints.
5
Recommendations
Clear, transparent advice with explanations, alternatives, risks, costs and rationale.
6
Implementation
Executing the agreed actions efficiently and accurately.
7
Ongoing review
Keeping the plan relevant as life, legislation, markets or circumstances change.
8
Communication and service standards
Clarity on response times, reporting, review frequency and who you deal with.
9
Coordination with other professionals
Alignment with accountants, solicitors, mortgage advisers or trustees.
What this means for you
A firm that cannot describe its own process simply is worth pressing on until it can. Judge on the completeness of the journey, not reputation or product names.
Key takeaway

Judge a firm by the quality of its process, not the confidence of its pitch.

Chapter 7. How advisers add value, and where they don’t

People look for advice because they want better returns, less stress, fewer mistakes or clearer decisions. But not all value is obvious, and not all value is delivered by every adviser.

The key insight

Adviser value is not investment performance. It is behaviour, tax efficiency, structure and discipline, and the evidence is strongest where the relationship is ongoing.

The headline numbers

£47,706
Average additional wealth of advised households after a decade. ILC–Royal London
1.2%
Annual gap between fund returns and what the average investor actually earned, to 2024. Morningstar
Up to 3%
Net annual value Vanguard attributes to advisers following best practice, not from performance
+The wealth impact over time

ILC–Royal London tracked real UK households over a decade. Those advised between 2001 and 2006 were on average £47,706 wealthier by 2014/16: £31,000 more in pension wealth, £16,000 more elsewhere.

The proportionate impact was greater for people of more modest means: a 35% uplift for the non-affluent group against 24% for the affluent.

Most strikingly, those who maintained an ongoing relationship had pension pots 50% higher than those who took advice only once. A single conversation did not create that gap. A sustained relationship did.

+The gap between fund returns and investor returns

Morningstar’s 2025 Mind the Gap found that over the decade to December 2024 the average investor earned 7.0% a year, around 1.2 percentage points less than their funds’ 8.2%. Not because they chose bad funds, but because they moved in and out at the wrong times.

+The Vanguard framework

Advisers following best practice can add up to, or exceed, 3% net annually, through measurable behaviours rather than performance. Lower-cost funds add 0–100 basis points. Tax-efficient asset location up to 45. A structured withdrawal strategy up to 112 or more. Behavioural coaching alone can add up to 200 basis points, and more in acute stress.

+The wellbeing evidence

63% v 48%: advised people who felt financially secure, against those who never took advice (Royal London, 4,000+ customers).

44% v 10%: people combining healthy finances with a positive money mindset, ongoing adviser relationship against none (Aegon, 10,000+ adults).

Advised clients rated 82% satisfied with quality of advice, 81% communication, 81% trustworthiness. Asked why they use a planner, more than half say the primary benefit is peace of mind.

An investor who stayed invested through 2020 earned 62%. One who moved to cash at the March bottom and reinvested in July earned 37%.

On a £500,000 portfolio, that 25 point gap is £125,000, more than fifteen years of an £8,000 annual advice fee, lost or preserved in a single decision.

An honest observation about scale

The percentage gap is the same for every investor. The pound value is not. On £20,000, a 1.2% improvement is £240 a year. On £1.5 million it is £18,000. This is not an argument that smaller portfolios do not deserve good advice. They do. It is an honest observation about why some of an adviser’s value is genuinely proportional to the sum involved.

Five claims worth questioning

+“We can consistently beat the market.”

There is no evidence retail advisers repeatedly outperform. This is the one claim here that is a regulatory matter rather than judgement: FCA rules require a financial promotion to be fair, clear and not misleading, and a promise of consistent outperformance is none of the three.

+“Our portfolios are unique.”

Most advisers use variations of the same evidence-based principles. The real differentiator is process, planning and behaviour support, not portfolio design.

+“We can predict what the market will do next.”

Short-term prediction is statistically impossible. Good advisers focus on discipline, not forecasts.

+“Our fees pay for superior performance.”

Fees should align with complexity, service and planning depth, not performance claims nobody can guarantee.

+“We cover everything.”

Advisers cannot legally write wills, draft trusts, give detailed tax advice or manage property portfolios. A good adviser is honest about the limit of their competence and introduces specialists.

The honest caveat

None of this means every adviser adds 3%, or that every client ends up £47,706 wealthier. Vanguard is explicit that advisers can add value if they follow the techniques shown to work. A reactive adviser doing minimal planning adds considerably less. The question is not whether advice is worth it in general. It is whether the specific adviser you are considering will create more value than they cost, at your complexity, over your horizon. And one disclosure: Xentum sells ongoing full financial planning, which is precisely the service this chapter’s evidence supports. We did not commission any of that research, but we do have an interest in you finding it persuasive.

That disclosure is not incidental. Before publishing, we put the final draft through a deliberately hostile review, asking where the text showed bias toward our own service and our own way of charging, and what an unbiased alternative would say. Several sections were rewritten as a result, including parts of this one. We mention it because you should assume a firm’s own guide is partial unless it can show what it did about that.

What this means for you
Judge an adviser against this evidence. Ask how they coach behaviour in a falling market, how they structure withdrawals, and what they do about tax location. Those are the levers that actually move the number.
Key takeaway

Advisers earn their fee through behaviour, tax and structure, not by picking better investments.

Chapter 8. Common mistakes when starting out

Before you even get to choosing an adviser, there are mistakes that make the process slower, more stressful and more expensive than it needs to be.

The key insight

Every one of these is yours to fix, for free, before you hire anyone.

MistakeDo instead
01Starting without clear goalsReflect on what you want your future to look like. Do not expect an adviser to define your goals for you
02Focusing on products instead of outcomesStart with priorities and strategy. Products are tools
03Underestimating accurate informationGather complete, current records before the process begins
04Expecting the plan to be a one-off eventView planning as ongoing maintenance
05Assuming complexity means more productsAim for clear, coherent structures. Simplicity usually improves outcomes
06Unrealistic expectations about timingAllow time for proper analysis and thoughtful recommendations
07Not considering the full pictureInclude property, mortgages, business interests, cash and tax exposure
08Ignoring emotional factorsBe open about your behaviours, fears and preferences
09Assuming every problem has a technical fixUse planning to explore choices, not just numbers
10Treating planning as separate from lifeSee it as a framework supporting decisions across the whole picture

If one does not know to which port one is sailing, no wind is favourable.

Seneca
What this means for you
Pick the two you are most guilty of and fix them this month. Both are free, and both make every subsequent conversation cheaper and better.
Key takeaway

The most expensive mistakes happen before you hire anyone.

Chapter 9. Finding the right guide

A financial adviser is someone you trust with decisions that affect your children, your future stability and your long-term wellbeing.

The key insight

Almost everyone has had to choose an expert they could not judge on technical grounds. The clearest example is a surgeon, and you would not choose the most reassuring one. You would choose the most straightforward.

Seven things the right adviser does

1
They start with you, not themselves
They begin by understanding your life, goals, concerns and values, not your products. The wrong adviser jumps straight to solutions.
2
They are transparent, even when uncomfortable
They explain the limits of what they can do, the risks, the trade-offs, the full cost, and the reasoning behind every recommendation.
3
They listen more than they talk
Great advisers ask better questions than you expected. If you leave the first meeting feeling genuinely heard, that is a strong sign.
4
They demonstrate their process clearly
You should not have to guess how they work or how often you will review things.
5
They avoid predictions and promises
They focus on what can be controlled: discipline, structure, behaviour, tax efficiency.
6
They talk about your life, not their products
Financial planning is about life first, money second.
7
They are happy to say “we’re not the right fit”
If an adviser will recommend a different firm because it is better for you, that is one of the strongest marks of integrity there is.

Trust doesn’t come from confidence. It comes from clarity, competence and honesty.

Ten questions to ask any financial adviser

Put these to every firm you meet, this one included, and compare the answers written down.

1
What will I pay in total in year one, and each year after, in pounds rather than percentages?
A written figure covering all five layers: advice, platform, investment management, fund charges, transaction costs.
2
Show me that same total on a portfolio half this size, and one twice it.
How the charging model behaves at different wealth levels, and whether you sit on the favourable side.
3
Which of the four roles do you perform yourselves, and which do you outsource?
Adviser, platform, investment manager, fund manager. A firm filling more than one should say what each costs.
4
Are you independent or restricted, and what does that exclude for me?
A straight answer. Restricted is not a problem in itself; not being told plainly is.
5
What is the scope: single issue, financial advice or full planning? What is not included?
Specifics on cashflow modelling, tax and estate work, and what triggers an additional fee.
6
Describe your process from first meeting to first review.
A process they can describe without notes, with your responsibilities in it as well as theirs.
7
Who will I deal with day to day, and what happens if they leave?
Whether you are buying an individual or a firm, and whether anyone has thought about succession.
8
Who owns the firm, and has that changed recently?
Ownership changes often precede changes to fees, service model and the people you deal with.
9
Tell me about a time you told a client something they did not want to hear.
A specific example rather than a principle. Difficulty answering is itself informative.
10
What would have to be true for you to tell me I do not need you?
Whether they can describe a version of you better served by DIY, a robo service, another firm, or nothing at all.
What this means for you
Answers in writing beat answers in a meeting, and figures in pounds beat figures in percentages. An adviser who answers question ten properly has told you more than the other nine combined.
Key takeaway

Whoever you choose, including if that is nobody and you do it yourself, choose deliberately.
