What changes the price
- DIY versus accountant: the Companies House fee is fixed; the accountant fee is for advice and correct setup.
- Share structure: multiple shareholders or share classes need more thought than a single-director company.
- What is bundled: registration for Corporation Tax, PAYE and VAT, plus a first-year accounts plan, may be included or extra.
- Registered office and address services: some accountants include a registered office, others charge for it.
The Companies House fee versus the accountant fee
Registering a company directly on GOV.UK costs GBP 50 and takes minutes. An accountant charges roughly GBP 50-150 on top, and the difference is setup done right: the correct share structure, registration for the taxes you actually need, a sensible salary-and-dividend plan, and avoiding the common first-year mistakes. If your setup is a plain single-director company, DIY is perfectly reasonable; if there are co-founders, investment or share classes involved, the advice is worth more than the fee.
What to sort out at the same time
Forming the company is step one. New companies also need to register for Corporation Tax within three months of starting to trade, set up a business bank account, register for PAYE if paying a salary, and consider VAT. An accountant setting the company up usually handles the tax registrations and points you at the rest, which is a large part of what the formation fee buys over the bare GBP 50 filing.
Check the firm is actually regulated
Price is only half the decision. "Accountant" is not a protected title in the UK, so the cheapest quote is not always from a qualified, accountable firm. Any business doing accountancy work is legally required to be supervised for anti-money-laundering, and the strongest firms are also members of a body such as ICAEW, ACCA or AAT. Before you pay, confirm the firm is AML-supervised and on the public record.
