What changes the price
- Package tier: entry packages cover the essentials; higher tiers add VAT, payroll and personal tax.
- Whether you are inside or outside IR35: inside-IR35 working through an umbrella changes what you need.
- Add-ons: bookkeeping software, references for mortgages, and IR35 contract reviews may cost extra.
- Number of contracts and expenses: heavier admin nudges you into a higher tier.
What a contractor package includes
A typical fixed monthly fee of GBP 60-150 plus VAT usually covers your company year-end accounts, Corporation Tax, a director payroll, quarterly VAT, your Self Assessment, and access to cloud software with support. Providers pitch this as an all-in price precisely because contractor affairs are predictable - one director, one contract stream, similar every month - which is what makes the fixed fee viable.
IR35 and why it affects the decision
IR35 decides whether a contract is genuine self-employment or "disguised employment". Outside IR35, working through your own limited company with an accountant is efficient and the packages above apply. Inside IR35 - common since the 2021 off-payroll reforms shifted the decision to end clients - you may work through an umbrella company that runs PAYE for you, in which case you need far less accountancy. Know your status before you pay for a full limited-company package you may not need.
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.
