How Much Does Bookkeeping Cost in the UK?

UK bookkeeping and accounting has no standard pricing, most firms do not publish fees online, and most small business owners have no reference point for what they should be paying. The result is a market where some businesses pay twice what they should for a service they barely use, and others pay a rock-bottom price and receive less than they think.

This guide builds a scope-based pricing framework — three tiers, defined by what they include, so you can locate your business and judge whether your current arrangement is fair value.

Why scope determines cost more than business size

The most common question is “how much should a sole trader pay?” or “how much does a limited company need?” But these questions produce ranges so wide they are unhelpful — a sole trader with 200 transactions a month and quarterly VAT has fundamentally different accounting needs from a sole trader with 10 invoices a year and no VAT.

The more useful question is: what services do you actually need? Once you define the scope, the price follows.

Three scope tiers cover the vast majority of UK small businesses:

Tier 1: Compliance only

Who this fits

Sole traders and freelancers with straightforward income — typically one main source of income, fewer than 50 transactions per month, not VAT-registered.

What it covers

• One-off self assessment tax return preparation and filing with HMRC
• Basic annual accounts (not statutory accounts — these are for your records and tax return)
• Answering questions about what can be claimed as expenses

What it does not cover

• Bookkeeping (you are responsible for maintaining your own records)
• VAT returns
• Payroll

Cost range

£150–£400 per year for a sole trader self assessment return. Most firms in this tier charge one-off annual fees rather than monthly retainers.

Monthly equivalent

£12–£33/month spread over a year.

Important from April 2026: Sole traders with income above £50,000 are now required to follow Making Tax Digital for Income Tax Self Assessment (MTD for ITSA), which requires digital record-keeping and quarterly updates — not just an annual return. This means many businesses that were comfortable in Tier 1 now need something closer to Tier 2.

Tier 2: Compliance and bookkeeping

Who this fits

VAT-registered sole traders, small limited companies, and any business where the accounting work happens throughout the year — not just in January.

What it covers

• Monthly bookkeeping (bank reconciliation, categorisation of income and expenses, supplier invoices)
• Quarterly VAT returns submitted under Making Tax Digital for VAT
• Director payroll (limited companies)
• Year-end statutory accounts and corporation tax return (limited companies)
• Director self assessment

Cost range

For sole traders (VAT-registered or higher transaction volume)

• Basic bank reconciliation and expense categorisation: £80–£150 per month
• Add VAT return preparation: an additional £30–£60 per month
• Full bookkeeping plus self assessment as an annual retainer: £40–£80 per month

For limited companies

• All-in compliance package (bookkeeping, VAT, payroll, year-end accounts, CT return, director self assessment): £100–£300 per month
• The 6 Figure Bookkeeper survey found the median monthly fee for routine sole trader bookkeeping was approximately £150.50.

The entry-price shift: Online-first accounting services — those without physical offices that use cloud software as the delivery mechanism — have brought entry prices for this scope of service to around £29–£75 per month. This is the most significant pricing change in UK small-business accounting in the past decade and is driven by Xero and similar platforms eliminating the data-entry overhead that previously justified higher fees.

Tier 3: Advisory

Who this fits

Businesses that want their accountant actively involved in financial decisions, not just filing returns, but producing management accounts, forecasting, supporting decisions about pricing, hiring, and tax planning.

What it covers

• Everything in Tier 2
• Monthly or quarterly management accounts (profit and loss, balance sheet)
• Cash flow forecasting
• Proactive tax planning (corporation tax, pension contributions, salary structure)
• Strategic advisory conversations

Cost range

£250–£600 per month for most growing SMEs. Above £600 per month, the service typically includes dedicated advisory hours and begins to resemble fractional finance director support rather than standard accounting.

What drives costs within any tier

Once you know which tier you need, the specific position within the price range depends on:

Transaction volume

Bookkeeping is fundamentally a volume business. More transactions mean more time spent on bank reconciliation and categorisation. A business with 20 transactions per month takes far less time than one with 200. Published market benchmarks show bookkeeping costs at approximately £0.50–£1.50 per transaction.

Quality of your records

Disorganised receipts, mixed personal and business spending, and missing invoices cost your accountant time. Businesses that keep clean records and use accounting software with bank feeds consistently pay less.

Whether you are VAT-registered

VAT registration adds quarterly return work. For a business with straightforward UK sales, the additional cost is typically £30–£60 per month. For businesses with multiple VAT rates, international sales, or partial exemption, it can be significantly more.

Whether payroll is involved

Director payroll for a single-director company is simple. Payroll for employees with varying hours, PAYE submissions, and pension enrolment adds a material amount — typically £5–£15 per employee per month.

Software adoption

Accountants who work in Xero, QuickBooks, or FreeAgent can see your bank transactions, categorise them, and reconcile your books far more efficiently than those working from spreadsheets and PDFs. Most online accounting services include the software licence in their fee.

How to check if you are paying the right amount

Three tests

Test 1: Scope match

List the services your accountant provides and match them to the tiers above. If you are paying Tier 2 prices (£100–£300/month) but receiving only a Tier 1 service (an annual return), you are overpaying. If you are paying Tier 1 prices for a business that now needs quarterly MTD reporting, you are underpaying in a way that may cause compliance problems.

Test 2: Hourly equivalent

If your accountant charges an annual fee of £1,500 for a sole trader self assessment that takes approximately 3–5 hours of their time, the implied hourly rate is £300–£500. Senior tax advisers command £150–£300/hour. A £1,500 annual fee for a simple return is at the high end of the market.

Test 3: Service included

At any price point, the service should include a named point of contact (not just a ticketing system), deadline reminders, and access to answer questions during the year. If your accountant is unreachable until January, you are paying for a filing service, not an accountant.

Making Tax Digital is changing the pricing structure

From April 2026, sole traders and landlords with income over £50,000 must follow MTD for ITSA — quarterly digital updates to HMRC instead of an annual return. From April 2027, this extends to income over £30,000.

This structural change makes the distinction between Tier 1 and Tier 2 increasingly important. Businesses that previously needed only an annual tax return now need quarterly engagement — and the pricing for that ongoing relationship is a monthly retainer, not a one-off fee.

The practical implication: if you are approaching the MTD threshold, compare monthly retainer pricing now rather than scrambling to find a new arrangement in January.

Frequently Asked Questions

How much should a small UK business pay for bookkeeping?

Many sole traders pay around £150–£400 a year for basic compliance, while limited companies needing monthly bookkeeping and VAT often pay £80–£300 a month depending on volume and extras such as payroll.

Does Making Tax Digital increase bookkeeping costs?

It can. MTD requires digital records and compatible software, so firms that previously did annual-only work often need more frequent bookkeeping support.
