Accountants for Growing Businesses Across Oxfordshire & Essex
Real meetings. Clear advice. No surprise tax bills.
We work with property landlords, tradespeople, and professionals across Oxfordshire and Essex who want an accountant who helps with the structure, the profitability, and the operational side, not just the filing.
“Sam was absolutely fantastic to deal with. He got our tax completed and lodged very quickly. Nothing was too much trouble. I highly recommend him to anyone needing reliable, knowledgeable, and genuinely supportive accounting services.”
— Yvette Percy, Bicester
- CLIENT SUCCESS STORY -
One client came to us turning over around £4m but making less than £40k profit. By helping them get better visibility over job profitability, improving pricing and quoting, and tightening up operational controls such as materials and stock management, the business transformed its understanding of performance. Turnover stayed broadly the same, but profits increased dramatically to around £400k, giving the directors clearer control and confidence in their business.

Accountants who actually help you run the business
Filing and compliance is the bare minimum. What most owner-managed businesses actually need is someone telling them whether they’re trading through the right structure, whether the numbers add up to a profitable business, and what to do about it before year end, not after.
Most firms won’t tell you any of that. You get a tax bill bigger than you expected, or you find out a year too late that a different setup could have saved you thousands. By then the advice you needed is the advice you never got.
We set up SD Accountancy to work the other way round. Structure and tax planning sorted from the start. Clean numbers you can rely on through the year. Real meetings when something big lands.
Want to talk it through? Fifteen minutes on the phone, no fee, no obligation.

Meet us
A video call to start, or we come to you if you’re in Oxfordshire or Essex. We look at what you’re doing now, what’s working, and what’s missing.

Regular check-ins, clear advice, and no surprise bills at year end.
Step one starts here. Fifteen minutes, no fee.
Who We Work With
The sectors we know inside out. If your business sits in one of these, we’ll have seen the questions, the structures, and the tax angles before.
Sole traders, limited companies, and CIS contractors. We handle the CIS returns, the tax, and the year end.
Solicitors, surveyors, consultants, and small practices. Tax planned through the year, books always clean.
From founder-only to first hires and beyond. Setup, growth, hiring, and the right tax structure for what comes next.
We also work with businesses in many other sectors.
Work in one of these sectors? Let's see if we're a good fit.
Who we’re not for
We’re probably not the right fit if you’re only looking for the cheapest accountant, or a hands-off, filing-only service. If your priority is the lowest possible fee and a tax return submitted once a year with no conversations in between, there are firms set up to do exactly that. We’re not one of them.
If you want an accountant who’s involved through the year, helps you make decisions, and saves you money in places you didn’t know to look, we will be.

“Sam Dallimore has been outstanding. Clear advice, fast responses, and no nonsense. He took over my accounts and immediately brought structure, accuracy, and confidence back into the process. He explains things properly, handles everything on time, and genuinely looks out for the business rather than just processing numbers. Highly recommended for any small or growing company that wants a reliable accountant who actually cares about getting it right.”

Why SD Accountancy
We help you understand the numbers, make better decisions, and build a more profitable business.
Founded by ACCA-qualified accountant Samuel Dallimore, SD Accountancy was built around a simple idea: business owners deserve clear advice, direct access to their accountant, and support that goes beyond filing deadlines.
When you work with us, you’re not passed between departments or left waiting days for a response. You’ll deal directly with the people responsible for your accounts, tax and business advice.
We work with owner-managed businesses across Oxfordshire and Essex, particularly within construction, trades, property and professional services. Whether you’re looking to improve profitability, understand your tax position, grow your business, or simply gain confidence in your numbers, we’re here to help.
Our clients choose us because they want more than an accountant who files accounts once a year. They want an accountant who understands their business and is available when they need support.
Our Guarantee
You meet your accountant. You always speak to the person doing your work.
Fees are agreed in writing before we start, and never change without a conversation first.

Transparent Pricing
Every client is different, so we don’t force businesses into one-size-fits-all packages.
We’ll discuss what support you need, agree the scope of work upfront, and provide a clear proposal before we start.
Many clients choose to spread the cost through monthly payments, helping them budget for their accountancy support throughout the year.
Common Questions
How much do your services cost?
Every business is different, so we don’t force businesses into one-size-fits-all packages. We’ll discuss what support you need, agree the scope of work upfront, and provide a clear proposal before we start. Many clients choose to spread the cost through monthly payments, helping them budget for their accountancy support throughout the year.
Do I have to come to your office?
No. We prefer in-person meetings because they work better, but we can come to you, meet at your premises, or jump on a video call. Most clients do a mix through the year.
I'm already with another accountant. Is switching difficult?
It shouldn't be. We handle the handover. We write to your current accountant, collect your records, and take it from there. Most switches take a couple of weeks with little work from you.
Which software do you use?
We set you up with software that suits your business and handle the setup. But we're Xero partner
Do you work with my industry?
We specialise in property landlords, trades and construction, and professional services. If you're outside those, talk to us anyway. If we're not the right fit we'll tell you and point you somewhere that is.
When should I hire an accountant?
Sooner than most people do. Getting the structure and software right at the start saves tax and stress later. If you're already trading, any time of year is a good time to review.
Book Your Free Discovery Call
Fifteen minutes on the phone. We'll ask about your business, your current setup, and what's on your mind. You'll come away with a clear answer on whether we're the right accountant for you. No fee and no obligation either way.
