Why Clients Choose Simpson Wreford LLP

Over 135 years of expertise in London

Simpson Wreford LLP was founded in 1886 and has operated from the Royal Arsenal, Woolwich, for generations. We have advised clients through every significant change in UK tax legislation — from the introduction of PAYE in 1944 to the current digital transformation of tax. That continuity of experience is something no recently-established firm can offer.

Fixed fees, agreed upfront

We quote a fixed fee before we begin any work. Our clients always know what they will pay before we start, and we discuss any scope changes with you before they affect your bill. No hourly rate surprises.

A named contact who knows your business

When you call us, you speak to someone who knows your accounts, your history, and your goals. We do not operate a call centre model where your affairs are handled by a different person each time.

Proactive advice, not just annual compliance

Tax planning is most effective when it happens throughout the year, not at year-end. We meet with clients regularly, flag relevant changes in tax legislation, and identify opportunities before deadlines pass.

Regulated and quality-assured

Simpson Wreford LLP is a member of the Institute of Chartered Accountants in England and Wales (ICAEW) and the UK200Group — the UK’s leading quality-assured membership association of independent chartered accountancy and law firms. We are regulated, insured, and bound by a professional code of conduct.

QuickBooks Elite Partners and Xero-certified

We are one of a select number of QuickBooks Elite Accountant Partners in the UK, and are also Xero-certified and experienced with Sage. We help clients migrate to cloud accounting, manage their software, and use it to stay compliant with Making Tax Digital.

What Our Clients Say

Our clients range from sole traders to the chairmen of internationally recognised companies. Here is what a few of them have said about working with us.

"For over 33-years the Simpson Wreford team have steered Brigade Electronics through the shark-infested waters between a one-man start-up and the market leading £30m Brigade Electronics plc of today. That speaks for itself."
"This is an accountancy firm really committed to saving the client’s money and making doing the books much easier. We are delighted by the quality of service we continue to receive."
"Simpson Wreford have been so much more than an accountancy firm and we can truly say without them we would not be where we are today — a successful and thriving organisation."

Making Tax Digital for Income Tax — Are You Ready?

Making Tax Digital (MTD) for Income Tax Self-Assessment became mandatory from April 2026 for self-employed individuals and landlords above the relevant income threshold. Under MTD, you must keep digital records and submit quarterly updates to HMRC, followed by a final declaration.

Simpson Wreford offers two simple, low-cost service options to keep you compliant:

Simple Spreadsheet Service — complete our custom Excel template quarterly; we review and submit to HMRC from £50 + VAT per submission

Enhanced QuickBooks Service — for those who want more automation, with options from self-managed bank feeds to full data entry and filing by us

If you are not yet registered for MTD for Income Tax, contact us now. ICAEW is advising all eligible taxpayers to register without delay.

Serving London, Kent, and the South East

Our office is at Wellesley House, Duke of Wellington Avenue, Royal Arsenal, Woolwich, London SE18 6SS — within easy reach of Greenwich, Lewisham, Bexley, and across Kent. We are happy to visit clients at their premises for an initial consultation, or to meet at our office.

Through our membership of the UK200Group, we also have connections with quality-assured accountancy and law firms across the UK and internationally, enabling us to support clients with cross-border requirements, overseas expansion, and international tax matters.

Common Questions

These are some of the questions we are most frequently asked by new and prospective clients.

What does a chartered accountant do for a small business?
A chartered accountant prepares financial statements, files tax returns, advises on tax planning to reduce your liability, handles HMRC correspondence, manages payroll and VAT compliance, and acts as a strategic adviser on business decisions that have financial or tax implications.
How is Simpson Wreford different from an online accountancy service?
We provide a genuinely personal service — a named chartered accountant who knows your business, meets with you regularly, and gives proactive advice rather than just reacting to what you send them. Our fees are fixed, our team is ICAEW-regulated, and we have been providing this level of service since 1886.
Do I need to be Making Tax Digital compliant?
If you are VAT-registered, you are already required to use MTD for VAT. If you are self-employed or a landlord with qualifying income, MTD for Income Tax has applied since April 2026. We can assess your situation and handle compliance on your behalf.
Where are you based and what areas do you cover?
We are based at Royal Arsenal, Woolwich, London SE18. We serve clients across London and the South East, including Greenwich, Lewisham, Bexley, and Kent. We are also able to serve clients nationally and internationally through the UK200Group network.
