Accountant Costs UK 2026: Real Prices, Hidden Fees and How to Compare Accountants for Small Business

Written by Sam | 18 September 2026

A quote for £300 inc VAT per month can be good value for a growing limited company, or expensive if it only covers annual accounts and a Corporation Tax return.

The difficult part is rarely finding an accountant who gives you a price. It is understanding what that price actually buys, what has been left out and when the next invoice might arrive.

This guide explains how to read and compare accountant quotes in 2026, with realistic UK price ranges for limited companies and growing SMEs.

Start with the total service, not the headline price

For a growing UK limited company, £300 inc VAT per month is a sensible starting point for a broad package involving regular bookkeeping, VAT, payroll, year-end accounts, Corporation Tax and practical support.

It is not a universal price. A simple company with clean records may pay much less, while a business with employees, stock, overseas transactions or advisory requirements may pay considerably more.

The important question is:

What work is included in the quoted price, and what work is likely to be billed separately?

A quote of £100 per month may look cheaper than £300 per month, but the lower price might exclude bookkeeping, VAT, payroll, software, director Self Assessment and routine advice. Once those extras are added, the difference may be smaller than expected.

When you compare accountant services, turn every quote into an estimated annual cost before making a decision.

Realistic 2026 cost ranges for limited companies

These figures are broad market ranges for UK limited companies. They are useful for budgeting, but your final quote will depend on complexity, transaction volumes and the level of support you need.

Basic compliance

For annual statutory accounts, a Corporation Tax return and standard Companies House filing support, a small active limited company may typically budget:

• £750–£2,000 per year

• Approximately £60–£167 per month when spread across the year

This type of package may suit a company with few transactions, no employees and no VAT registration. It often does not include day-to-day bookkeeping or regular management reporting.

Check whether the price includes the confirmation statement. Some accountants treat this as a separate annual service.

VAT and payroll packages

For a VAT-registered company with a director and a small number of employees, a broader compliance package may commonly fall around:

• £120–£250 per month

• Approximately £1,440–£3,000 per year

The quote may include VAT returns, PAYE submissions and basic payroll administration. However, ask how many employees and payroll runs are covered.

A package for one director is not necessarily the same as a package for five employees. Starters, leavers, pension administration and irregular payroll runs can all affect the cost.

Bookkeeping

Bookkeeping is one of the biggest reasons quotes vary.

If the accountant maintains your ledgers, reconciles your bank account and processes invoices and expenses, bookkeeping may be priced at:

• £100–£500 per month for a small limited company

• Around £20–£50 per hour where the firm charges for time

• More where transaction volumes are high or records require correction

Some firms include bookkeeping up to a set number of transactions. Others describe it as “light bookkeeping” without giving a clear limit. That wording deserves further questions.

Advisory-led support

If you want regular management accounts, cash-flow forecasting, tax planning, budgeting or support with growth decisions, expect a higher fee.

A more involved package may cost approximately:

• £300–£600+ per month

• More for complex groups, international activity, substantial payroll or frequent advice

This can represent good value for a growing SME if the service helps you make better decisions. But do not pay for advisory support unless the quote explains exactly what it includes.

How to read an accountant’s quote

Before comparing the numbers, read the quote in five sections.

1. Identify the core deliverables

Look for specific descriptions of:

• Annual statutory accounts

• Corporation Tax return

• Companies House filing support

• VAT returns and the VAT scheme covered

• Bookkeeping and bank reconciliations

• Payroll and pension administration

• Management accounts

• Tax planning or business reviews

• Director’s Self Assessment

• Accounting software and receipt-capture tools

“Full service” is not a sufficient description by itself. Ask the accountant to replace broad labels with specific deliverables and frequencies.

2. Check the assumptions

Most quotes are based on assumptions. These may include:

• A maximum number of monthly transactions

• A set number of bank accounts

• One company and one accounting period

• A fixed number of employees

• Monthly or quarterly payroll

• Straightforward UK VAT

• Records being complete and submitted on time

• Use of a particular accounting software package

If the assumptions do not match your business, the quote may not be realistic.

3. Read the exclusions carefully

Exclusions often contain the real cost of the service. Look for references to:

• Additional bookkeeping

• Complex VAT or overseas sales

• Corporation Tax planning

• HMRC enquiries

• R&D tax claims

• Company restructures

• Business acquisitions or disposals

• Dividend or director loan advice

• Confirmation statements

• Registered office services

• Software subscriptions

• Catch-up bookkeeping

• Urgent or out-of-hours work

An exclusion does not mean the accountant is being unreasonable. It means you need to understand what the work would cost if you need it.

4. Find the extra-work rate

Ask for the hourly rate or fixed-fee approach for work outside the package.

For example, a firm may charge separately for:

• Correcting historic bookkeeping

• Preparing additional reports

• Dealing with HMRC correspondence

• Supporting a tax enquiry

• Filing amended returns

• Producing lender or investor information

You should also ask whether the accountant must obtain your approval before starting chargeable extra work.

5. Check how fees can change

A fixed monthly fee is only useful if you understand when it can be reviewed.

Ask:

• Can the fee increase during the first year?

• What happens when turnover grows?

• Are extra employees automatically charged?

• Is there an annual price review?

• Is there a minimum contract term?

• What notice is needed to leave?

• Are setup and onboarding fees payable?

A good engagement letter should explain the pricing structure in plain English.

Hidden and variable fees to question

The following charges are not necessarily hidden fees, but they are commonly missed when business owners compare quotes.

Transaction limits

A package may cover 100 or 200 monthly transactions, with additional work charged above that threshold. Ask whether the limit includes bank feeds, sales invoices, purchase invoices, expense claims and transfers.

Payroll changes

The headline price may cover a director-only payroll. Extra employees, pension enrolment, workplace benefits, payroll corrections and additional pay runs may cost more.

Director Self Assessment

Company accounts do not automatically include a director’s personal tax return. A separate Self Assessment fee may commonly be £150–£400 per year, depending on the director’s circumstances.

Software

Some accountants include Xero, QuickBooks, FreeAgent or another platform. Others pass the subscription cost to you. Confirm who owns the account and what happens to your data if you leave.

Clean-up work

If your records are incomplete, unreconciled or spread across spreadsheets, the accountant may charge a one-off fee before starting the regular service.

Advisory time

Tax planning, cash-flow forecasting, funding support and management meetings may be outside a compliance package. Ask how much contact is included and whether meetings have a time limit.

How to compare accountants for small business

To get like-for-like quotes, send each accountant the same information:

• Company structure and year-end date

• Approximate annual turnover

• Monthly transaction volume

• Number of bank accounts

• VAT registration and VAT scheme

• Number of employees

• Payroll frequency

• Accounting software currently used

• Whether bookkeeping is up to date

• Any overseas sales, stock or multiple income streams

• The advice you expect during the next 12 months

Then ask each accountant to price the same service list.

A useful comparison sheet should include:

Service	Included?	Limit or assumption	Extra fee
Annual accounts	Yes/No	What records are required?	Amount or hourly rate
Corporation Tax return	Yes/No	One company?	Amount or hourly rate
VAT returns	Yes/No	How many and which scheme?	Amount or hourly rate
Bookkeeping	Yes/No	Transaction limit	Amount or hourly rate
Payroll	Yes/No	Number of employees	Per payslip or monthly fee
Director Self Assessment	Yes/No	One or more directors?	Annual fee
Software	Yes/No	Which platform?	Subscription cost
Advice and meetings	Yes/No	Time or frequency limit	Hourly or fixed fee

This is the practical foundation of how to find an accountant for small business uk owners can trust: compare the scope, not just the monthly figure.

Warning signs that a quote has scope gaps

Be cautious if:

• The accountant gives a price without asking about your company

• “Full service” is not defined

• There is no written list of exclusions

• No transaction or payroll limits are stated

• You cannot find an hourly rate for extra work

• The fee is unusually low but the service list is vague

• The quote expires quickly and you are pressured to sign

• The accountant avoids questions about software and data ownership

• You are promised large tax savings before your records are reviewed

• No engagement letter is provided

Should you choose an online or high street accountant?

The cheapest option is not automatically the best option.

An online accountant may offer efficient cloud systems, fixed monthly pricing and convenient communication. A high street firm may provide face-to-face meetings and more traditional support. Both can be excellent or poor, depending on the people, processes and scope behind the quote.

Read our comparison of an online accountant versus a high street firm before deciding which model suits your company.
