What does a UK accountant do? Core services and specialist extras

Most UK accounting firms list the same core services on their websites. Beyond that, firms specialise – and some work can only be done by firms that hold a specific licence. Here is how to tell the two apart.

The core services almost every firm offers

If a firm works with small businesses, sole traders or landlords, you can expect most of these as standard. Many bundle them into a fixed monthly package.

Specialist services only some firms offer

These need particular expertise, and a few need a licence. Not every firm does them, so ask directly rather than assuming.

Who can call themselves an accountant?

“Accountant” is not a protected title in the UK – anyone can use it. Titles that are protected tell you more:

Whatever their title, every firm offering accountancy or tax services must be supervised for anti-money-laundering, either by a professional body or by HMRC. Professional bodies also require their members to hold professional indemnity insurance. It’s fair to ask a firm about both.

How firms usually charge

Always get the quote in writing, check exactly what it includes, and compare more than one. See our price guide for typical MTD fee ranges, and questions to ask before you choose.
