Sound familiar?
Still figuring out your own tax return each year?
Most sole traders in London are running their business, handling clients, and trying to stay on top of HMRC at the same time. Allowable expenses get missed. Deadlines creep closer than expected. And when you finally sit down with the books, last year’s records are in worse shape than you remembered.
- Self Assessment filed late, or rushed through with fingers crossed
- Expenses you could legitimately claim go unnoticed because nobody reviewed them
- No clear idea what your tax bill will be until HMRC sends the calculation
What having it handled looks like
Your tax return prepared accurately, your allowable expenses reviewed properly, and your liability visible well in advance. No last-minute scramble, and no guessing.
- Self Assessment prepared and filed accurately, well ahead of the deadline
- Allowable expenses reviewed each year so nothing is left on the table
- Tax bill estimated and visible months before it is due
- Fixed-fee quote agreed upfront so you know the cost before any work begins

Why sole traders choose us over a local firm
There are plenty of accountants in London. Fewer who give you a straight answer quickly, price their work transparently, and already understand how your type of business operates.
21 years of practical experience
Supreme Consulting has been working with sole traders and small businesses since 2005. That means a significant number of Self Assessment returns, expense reviews, and HMRC queries handled. Experience like that shows up quickly in the quality of the advice.
Cloud-based, wherever you are
Certified in Xero and QuickBooks Online, which means your records are current, accessible, and not sitting in a spreadsheet on someone else’s desktop. Working remotely with London-based clients is the norm, not an exception. Setup and migration are handled for you.
Fixed fees, agreed before starting
Every quote is fixed-fee and scoped in advance. You will not receive an invoice you were not expecting, and there are no hourly rates accumulating in the background while you send an email. Pricing is confirmed in writing before any work begins.
Up and running in four steps
Switching accountant or starting fresh follow the same process. It takes considerably less effort on your part than you probably expect.
A short discovery call
We start with a no-obligation conversation about your business, your current setup, and what you actually need from an accountant. No preparation required on your end.
A clear, fixed-fee proposal
You receive a written proposal covering exactly what is included, what it costs, and when things happen. Nothing open-ended, no hourly rate surprises later.
We handle the transition
If you are switching from another accountant, we manage the handover and deal with the previous firm on your behalf. Records are migrated to the cloud and integrations are set up. You do not need to chase anyone.
Your finances, running properly
Deadlines handled, tax position visible in advance, questions answered the day you ask them. You get on with running your business knowing the compliance side is covered, which is frankly how it should be.
“Stuart is a thorough efficient worker who produces good quality results at a reasonable price.”
Things sole traders usually ask us
Do you work with sole traders based in London, or only clients near your Hampshire office?
The majority of our clients are remote, and London sole traders are no different. Everything is handled digitally via Xero or QuickBooks Online, with communication by phone and email. There is no requirement to meet in person at any point, though calls are always available when you need one.
What does sole trader accounting actually cost?
Pricing depends on the scope of work — a standalone Self Assessment return costs less than a package that includes monthly bookkeeping and quarterly VAT. Every quote is fixed-fee and confirmed in writing before any work begins. You will not receive an invoice that differs from what was agreed.
My books are behind and a bit of a mess. Can you still help?
Catch-up and clean-up work is something we do regularly. Most new clients arrive with records in some state of disarray — it is more common than you would think. We will assess what needs doing and quote for it separately, so you know the cost before any catch-up begins.
Am I locked into a long-term contract?
No. There is no minimum term. If it is not working after three months, you are free to leave and your records will be in better order than when you arrived. We prefer clients who stay because the service is good, not because the contract makes it awkward to leave.
Can you advise me if I am thinking about going limited?
Yes, and it is a question we get regularly from sole traders once their income reaches a certain level. The answer depends on your specific numbers and circumstances — it is not always the right move, and the tax saving is often smaller than people expect once you account for additional filing costs. We will give you a straight answer rather than defaulting to incorporation.
How far in advance will I know what my tax bill is going to be?
As a rule, you should know your approximate liability well before the payment deadline, not the week HMRC sends the calculation. Once your bookkeeping is current and your records are on the cloud, we can give you a running estimate that updates throughout the year.
Stop guessing what your tax bill will be and just know.
Supreme Consulting handles Self Assessment, bookkeeping, and tax planning for sole traders across the UK. Fixed fees, prompt replies, and 21 years of practical experience behind every answer.
