The cheapest full-service accountant for UK contractors in 2025
Not cheapest software. Not cheapest base plan. Cheapest genuinely complete service — bookkeeping, VAT, payroll, tax returns and Companies House filings all included.
What "cheap" usually means in contractor accountancy
If you've searched for a cheap contractor accountant, you've probably found prices ranging from £19/month to £175/month. Most of the low end isn't what it appears.
The £19/month options are bookkeeping software — tools like FreeAgent or Xero. They'll help you raise invoices and track expenses. They won't file your VAT return, run your director's payroll, prepare your Self-Assessment tax return, or submit your year-end accounts to HMRC and Companies House. You still need to pay a human to do all of that — separately.
The £50–£70/month "accountancy" options typically have that base price for good reason: it doesn't include payroll, or VAT returns are charged per quarter, or Self-Assessment is a bolt-on. Add everything a contractor actually needs and you're often at £120–£160.
"The only price that matters is the fully-loaded cost — everything you need, nothing you don't."
Autobooks charges £89+VAT/month. That includes everything. Bookkeeping, quarterly VAT returns, director payroll, Self-Assessment, year-end statutory accounts, Companies House confirmation statement, and unlimited queries. There are no add-ons for standard contractor work.
That makes it — as far as we can verify — the cheapest full-service accountancy option available to UK one-man limited companies in 2025.

The hidden costs that make "cheap" expensive
Three pricing patterns to check before you sign up with any accountant.
The add-on trap
A low headline price that doesn't include VAT returns, payroll or Self-Assessment. Each one added separately — sometimes per quarter, sometimes annually. By the time you've ticked every box you actually need, you've spent 40–80% more than the advertised price.
The introductory rate
Some providers offer a discounted first 3 or 6 months, then step up to full price. If you're comparing on price, make sure you're comparing the ongoing price — not the promotional one. Always ask: "What will I pay in month 13?"
Software masquerading as a service
Bookkeeping software platforms are useful tools — but they are not accountancy services. If the "accountant" is actually an app that you operate yourself, you'll still need a human to file your returns. That cost needs to be added on top.
What to look for instead
A single monthly price that includes bookkeeping, VAT, payroll, Self-Assessment, year-end accounts and Companies House filing — with no qualifiers and no per-service charges for standard contractor work. That's the only meaningful comparison.
Price guarantee matters
Autobooks' price is fixed at sign-up. We don't run introductory rates that step up. The price you see on the pricing page is the price you'll pay in month 13, month 25, and month 37.
Specialisation reduces cost
Generalist accountants charge more because their overhead is higher — they need staff who know landlord tax, CIS, retail, employment law. We only work with one type of client. That focus is what lets us offer a lower price without cutting corners.

Every one of these is included in the standard Gold plan. None are add-ons, none are seasonal extras.
