Accountancy & Financial Services Marketing Statistics 2026: Firm Counts, Self Assessment and the Advice Gap

Two professions that used to grow on word of mouth alone are now shrinking in firm count while their addressable market expands. There are fewer accountancy practices in the UK than there were five years ago, fewer regulated advice firms than there were three years ago, and more taxpayers and more companies than at any point in the last decade.

That gap is the whole marketing story for 2026. Demand is being manufactured by policy, chiefly Making Tax Digital and the annual self assessment cycle, whilst supply consolidates into fewer, larger practices.

What follows is drawn from HMRC filing data, the FCA's Retail Mediation Activities Return, ONS business counts, the Financial Reporting Council's profession survey and the FCA's Financial Lives survey. Every figure has been checked on the source page. Where a number is soft, or American, or based on a small survey base, it says so.

Key accountancy and financial services marketing statistics for 2026

How many accountancy and financial advice firms are there in the UK?

Roughly 40,000 accountancy businesses and around 4,400 regulated retail investment advice firms. Both counts have fallen every year since 2020, and the fall is steeper on the advice side.

ONS UK Business Counts, accessed through Nomis, records 39,975 enterprises in SIC 6920 in 2025 against 43,245 in 2020 [1]. Within that, 30,575 are accounting and auditing activities, 7,670 bookkeeping and 1,730 tax consultancy.

The FCA's retail intermediary market data, published July 2026, shows 4,406 firms reporting retail investment revenue in 2025, 3,854 reporting mortgage revenue and 37,517 retail investment adviser posts [5]. Adviser headcount has barely moved. Firm count has not.

Average revenue per advice firm has risen 68% in five years whilst the number of firms fell 13%. That is consolidation, not growth. It changes the competitive set: you are not fighting 5,000 small firms for local search visibility any more, you are fighting a smaller number of better-resourced ones.

On the accountancy side, the Financial Reporting Council's 2025 profession survey counts more than 408,000 members across the seven UK and Ireland bodies, up 0.8%, alongside 3,760 registered statutory audit firms in 2024, down 24.9% since 2020 [10]. More qualified accountants, fewer registered audit firms. The people are staying; the small practices are folding into larger ones or dropping audit registration.

How do small businesses actually choose an accountant?

Most do not choose in any deliberate sense. They inherit an accountant through a recommendation and stay. Outsourcing is the norm rather than the exception, and it is rising.

The HMRC Individuals, Small Businesses and Agents Customer Survey 2023 found 71% of small businesses outsourced some or all of their tax affairs to an agent, split 33% outsourcing everything and 38% outsourcing part [3]. The 2022 figure was 66%. Sample: 2,082 small businesses.

The FCA's data gives a cleaner read on referral behaviour. Among advised adults who had used their adviser for two to three years or less and did not shop around at all, 35% said the reason was simply that the adviser had been recommended to them [7].

The marketing implication is worth stating plainly. If most acquisition happens through referral, search and content are not primarily acquisition channels for these firms. They are validation channels. The prospect already has a name, and the website has to survive the check. The review profile, the Companies House record, the FCA register listing and the named partner biographies do more conversion work than the blog.

The counterpoint is the 29% of small businesses that do not outsource, plus churn inside the 71%. Those are genuinely searchable audiences, and they cluster around trigger events: incorporation, a first VAT registration, a threshold crossing, a bad experience with the previous agent.

How big is the January self assessment spike, and when does it really start?

Enormous, and it starts much earlier than most practices market for. HMRC received 11,489,825 returns by 31 January 2026, of which 11,173,825 were online (97.25%) and 316,000 on paper [2]. An estimated one million customers missed the deadline entirely.

Sources: HMRC news releases, January to May 2026 [2][11][12]

Two things stand out. First, 737,891 returns were filed in April 2026 against 687,247 in April 2025, a record for the month [12]. The early-filer cohort is real, growing and almost entirely uncontested in paid search, because most practices only start bidding in November.

Second, 5.65 million returns were still outstanding on 1 January 2026 [11]. Roughly half the annual total is compressed into 31 days. If your cost per click in January is triple your November cost, that is why. The sane play is to acquire between April and September at low competition, not to buy the same panic clicks as everyone else in the last fortnight.

Digital self-service is growing underneath this. HMRC recorded 339,490 customers paying their self assessment bill through the HMRC app between 6 April 2025 and 4 January 2026, up 65% on 206,702 a year earlier [13].

Is Making Tax Digital a real demand driver for accountancy practices?

Yes, and it is the most precisely dated demand event the profession has had in years. The thresholds and start dates are published, so the size and timing of each wave of new compliance work is known in advance. HMRC confirmed more than 864,000 sole traders and landlords with qualifying income above £50,000 entered Making Tax Digital for Income Tax from 6 April 2026 [4].

Source: HMRC guidance, updated March 2026 [14]

Each cohort files quarterly updates as well as an annual return. For the April 2026 group the deadlines fall on 7 August 2026, 7 November 2026, 7 February 2027 and 7 May 2027, with the self assessment return due 31 January 2028 [4][15].

That converts an annual sales cycle into a quarterly one, and creates four panic moments per client per year rather than one. Retention opportunity and service-delivery risk in equal measure.

Separately, HMRC is making registration mandatory for tax advisers who interact with it on clients' behalf, phased from 18 May 2026 with the first deadline on 18 August 2026, backed by £36 million to modernise the system [16]. Expect "registered with HMRC" to appear as a trust signal on practice websites within a year, and expect it to mean very little once everyone has it.

How many people take financial advice, and how big is the advice gap?

Fewer than one in ten UK adults. The FCA's Financial Lives 2024 survey found 8.6% of adults, about 4.6 million people, received regulated financial advice in the 12 months to May 2024 [6].

That is up from 6.2% (3.2 million) in 2017 and 7.3% in 2020, but statistically indistinguishable from the 8.3% recorded in 2022. Of those advised in 2024, 74% used an adviser from a financial advice firm such as an IFA, which works out at 6.4% of all adults, or 3.4 million people [6].

The wider support picture is much larger. 41% of adults, some 22.2 million people, received some form of support about investments, pensions or retirement planning in that period, and 37% used information or guidance rather than regulated advice [6]. Government-backed services such as MoneyHelper and Citizens Advice reached 17% of adults.

So the advice gap is not a gap in demand for help. It is a gap between people seeking help and people paying a regulated firm for it. Roughly 20 million adults take guidance from somewhere every year and around 4.6 million convert to regulated advice. Everything a firm publishes that answers a guidance-stage question sits inside that 20 million pool.

The survey ran between February and June 2024 with 17,950 participants, so it predates the FCA's targeted support reforms. Treat it as a baseline, not a current snapshot.

Why do people with money to invest never contact an adviser?

Mostly because they think they do not need to. But the second tier of reasons is a discoverability problem, not a pricing problem.

The FCA asked adults who had not taken advice but plausibly needed it, defined as holding £10,000 or more in investible assets or in a DC pension they intended to access within two years. The base was 2,263 in 2024.

• 60% gave a "no need" reason, including 29% who said they could make decisions on their own [7]
• 22% had simply not thought about it or not got around to it [7]
• 22% said they could get support elsewhere, including 12% who said there was enough information or guidance available online [7]
• 16% cited access issues such as not being confident of finding a suitable adviser [7]
• 14% cited fees [7]
• 13% cited a lack of confidence or trust [7]

Separately, 40% of that group agreed they would not know where to start looking for an adviser, on a base of 1,355 [7]. And 24% did not trust advisers to act in clients' best interests, 39% did not think advisers were unbiased, and 21% did not think of advisers as professionals in the same way as solicitors and accountants [7].

Read those together and a pattern emerges. Fees are cited by 14%. Not knowing where to look is agreed by 40%. Firms spend most of their marketing effort justifying cost and almost none on being findable and legible to someone who has never engaged with the profession.

The 12% who say there is enough guidance online is the one to watch. That figure will not have shrunk since 2024, given what has happened to AI-generated answers since. Free guidance is the competitor, not the rival firm down the road.

What does a lead cost for accountancy and financial advice keywords?

There is no reliable UK-specific published benchmark for these categories, so the best available figures are American and should be treated as directional. On that basis, professional services leads sit above the cross-industry average.

LocaliQ's 2026 search advertising benchmarks, updated June 2026 [9]:

Source: LocaliQ 2026 Search Advertising Benchmarks [9]

Business Services, the closest proxy for accountancy, carries a cost per lead 40% above the all-industry average, driven by a weak conversion rate of 4.85% rather than by expensive clicks. Finance & Insurance is the odd one out: the cheapest clicks and the highest click-through rate in the table, paired with the worst conversion rate at 2.64%. That is characteristic of broad, research-stage traffic that clicks readily and converts badly.

Two caveats. These are US dollar figures across US accounts, and the category definitions are coarse. A UK practice bidding on "accountant near me" in a competitive city will not see a $5.87 click. LocaliQ also notes cost per lead fell overall in 2026 for the first time in five years.

How tightly does the FCA police financial promotions?

Tightly, and much more actively than three years ago. Enforcement volume roughly doubled in a single year, and social media is the main battleground.

The FCA reported its interventions led to 19,766 promotions being amended or withdrawn by authorised firms in 2024, up 97.5% from 10,008 in 2023 [8]. It also issued 2,240 alerts about unauthorised firms, assessed around 480,000 new websites, interviewed 20 finfluencers under caution and issued 38 alerts against finfluencer accounts.

Claims management companies accounted for 9,197 of the amendments, roughly 46% of the total, concentrated in housing disrepair and motor finance claims [8]. The headline number is not evenly distributed, and an ordinary advice firm is not facing anything like that intensity of scrutiny.

The rules sit in the FCA's finalised guidance on financial promotions on social media, FG24/1, published in March 2024 [17]. The practical constraints for an advice firm are that every promotion must be fair, clear and not misleading and must stand alone, which is what kills short-form video for most regulated messaging, and that unauthorised influencers promoting regulated products without approval may be committing a criminal offence.

Accountancy practices are not FCA-regulated for tax and compliance work and sit outside this regime, which is a genuine and underused advantage. An accountant can say things on LinkedIn that an IFA cannot.

Is AI eating the compliance and bookkeeping work?

Not yet at the headcount level, but the tasks most exposed are exactly the ones bookkeeping practices sell. UK evidence points to task displacement rather than job displacement, which is a positioning problem before it is a revenue problem.

The ONS reports that among businesses using machine learning for data processing, 41% saw impacts on administrative or clerical roles and 39% on data analysis roles [18]. Across all size bands, around half of businesses said AI had made no difference to overall headcount, and just under 7% of medium-sized businesses reported a reduction. Self-reported AI use among firms with 10 or more employees stood at around 35% by June 2026, though adoption is shallow, with the average adopter using about 1.6 AI technologies [18].

That is the shape of the threat. Data entry, reconciliation and reporting are being automated inside client businesses, eroding the volume of low-margin bookkeeping work practices sell. It does not remove the need for someone to sign off, interpret and advise.

Firms still marketing on price per month for bookkeeping are competing with a falling cost curve. Firms marketing on judgement, on the quarterly Making Tax Digital cycle and on liability are not.

How to read these numbers

Business counts and filing statistics are administrative data. HMRC's return counts and Companies House incorporation figures are near-complete records of actual events, not estimates. Companies House recorded 193,174 UK incorporations in the second quarter of 2026, with the register standing at 5,516,377 companies at the end of June [19].

FCA intermediary data comes from regulatory returns firms are obliged to file, but the FCA changed its classification methodology in 2025 and states plainly that data before and after 2025 is not comparable for some categories. The series used above come from the restated underlying tables. Treat single-year jumps with care.

Survey data carries the usual caveats and some unusual ones. Financial Lives 2024 has a large base of 17,950, but its subgroup questions do not. The barriers-to-advice figures rest on 2,263 respondents and the "don't know where to look" figure on 1,355. The shop-around comparison questions in the same report have bases as low as 118 and are not used here.

LocaliQ's benchmarks are aggregated from its own US client accounts. Not a random sample, not UK data, not sterling. Use them for the shape of the differences between categories, not the absolute numbers.

Making Tax Digital cohort sizes are HMRC counts of taxpayers meeting the threshold, based on prior-year returns. They are not counts of taxpayers who have actually signed up and filed.

What this means going into 2027

April to September is the cheapest acquisition window in the accountancy calendar and almost nobody uses it. Record April filing volumes show the early-filer cohort exists. Competition for it does not.

Making Tax Digital turns an annual relationship into a quarterly one from April 2027, when the £30,000 threshold brings in a much larger and less sophisticated cohort. Build the onboarding and content assets in 2026 or build them in a rush.

Advice firm consolidation continues. Expect fewer, better-marketed competitors in local search and a rising floor on what counts as a credible website.

The advice gap is a discoverability problem more than a pricing problem. Content answering "how do I find and check an adviser" addresses a far larger audience than content justifying fees.

Bookkeeping-led positioning gets harder every quarter. Practices selling compliance volume are marketing into a shrinking category. Practices selling judgement are not.
