Cambridge is the beating heart of the UK’s deepest technology cluster. From AstraZeneca’s global R&D campus to hundreds of AI, biotech, and clean energy startups clustered around Cambridge Science Park and the Biomedical Campus — plus some of the UK’s most active student and professional rental markets — Hayes delivers ACCA-qualified accounting that’s built around Cambridge’s unique innovation economy.
Cambridge biotech and AI startups can claim back up to 27p per £1 of qualifying R&D costs. Cambridge landlords pay income tax on net rental profit under Section 24 rules. Fixed-fee accounting from £75/month. Free consultation always.
Silicon Fen — Cambridge’s Business Sectors
Cambridge biotech, AI, and deep tech companies that invest in qualifying research and development can claim significant relief under HMRC’s merged R&D tax credit scheme. Loss-making companies receive a payable credit worth 27p for every £1 of qualifying expenditure under the Enhanced R&D Intensive Scheme (ERIS) for R&D-intensive SMEs, while profitable companies reduce their tax liability substantially. Qualifying expenditure includes staff costs, subcontractor costs, consumables used in R&D, cloud computing costs, and software licences. Hayes identifies every qualifying cost, prepares the technical narrative required by HMRC, and maximises your claim — typically submitting within 4–6 weeks of engagement.

Accountants & Tax Advisors in Cambridge, Cambridgeshire
Silicon Fen — the technology cluster centred on Cambridge — is the UK’s most productive innovation economy outside London. Cambridge Science Park, the world’s first, now houses over 150 companies. The Cambridge Biomedical Campus is one of Europe’s largest concentrations of medical research. AstraZeneca moved its global headquarters to Cambridge in 2016. Arm Holdings — the chip designer that powers virtually every smartphone on earth — was founded here. Over 800 technology companies operate within the Cambridge postcode. The total economic output of the Cambridge cluster now exceeds £19 billion annually.
For the founders, academics, and investors who drive this economy, tax is not a simple matter. R&D tax credits need to be claimed correctly from day one — many Cambridge startups overpay by failing to identify all qualifying expenditure. EIS and SEIS investor relief must be structured correctly to protect investors. EMI share schemes need HMRC advance approval before any options are granted. And as Cambridge companies grow, corporation tax, payroll, VAT, and cash flow management all become critical to survival through the scale-up phase.
Hayes serves Cambridge’s innovation economy with accounting that goes well beyond compliance. We think commercially, act proactively, and treat your tax position as a strategic asset — not a box-ticking exercise. Fixed fees, ACCA-qualified team, same-day response, and a genuine understanding of what it takes to build a Cambridge technology company.

Cambridge-Specific Specialist Services
AstraZeneca’s Cambridge campus, the Wellcome Sanger Institute, and dozens of Cambridge biotech companies all conduct R&D that qualifies for HMRC relief. We understand the technical requirements for pharma, genomics, and medtech R&D claims — preparing detailed technical narratives that withstand HMRC scrutiny and maximise the credit recovered.
Cambridge has one of the UK’s most active angel and early-stage VC communities. Enterprise Investment Scheme (EIS) gives investors 30% income tax relief on qualifying investments plus CGT exemption on gains. SEIS offers 50% relief for the very earliest stage. We prepare EIS and SEIS advance assurance applications for Cambridge startups — essential before approaching investors.
Cambridge University creates more spin-out companies than any other UK university. Academics commercialising IP face complex questions: how to structure the company alongside university employment, how to handle licence income, when and how to raise EIS investment, and how EMI options work alongside university equity stakes. Hayes has specific experience advising Cambridge academic founders through all of these decisions.
Cambridge has some of the UK’s highest rental yields outside London — student HMOs near the colleges and professional lets near the Science Park and Biomedical Campus both command premium rents. Cambridge landlords face Section 24 mortgage interest restrictions, HMO licensing costs that are tax-deductible, and capital gains planning on some of the most valuable residential property in England.
Cambridgeshire’s flat fenlands are some of England’s most productive arable farmland — growing significant proportions of the UK’s potatoes, sugar beet, celery, and grain crops. Fenland farming estates often carry significant inheritance tax exposure that Agricultural Property Relief and Business Property Relief can substantially reduce. We advise Cambridgeshire farming families on APR qualification, estate succession planning, and the tax treatment of farm diversification income.
Cambridge’s tech employers — Arm Holdings, Amazon’s Cambridge AI lab, Marshall Aerospace, and dozens of scale-ups — use large contractor workforces. IR35 applies to all of them and determines whether you pay income tax as an employee or through your limited company. We review every Cambridge tech contractor’s IR35 position, produce written status determinations, and set up your limited company to maximise after-tax income where outside IR35 applies.
Covering All of Cambridgeshire & East of England
Our service covers every corner of Cambridgeshire — from Peterborough’s logistics and distribution economy and Ely’s agricultural and cathedral city businesses to Huntingdon’s market town SME community and St Ives’ growing professional population.
FAQs
Client Reviews — Cambridge & Cambridgeshire
“I’m a co-founder at a Cambridge genomics startup. Hayes set up our EIS advance assurance, claimed R&D credits in our first year, and built our Series A investor pack. They recovered over £31,000 in R&D credits and our investors were impressed by the financial reporting quality. Outstanding.”
Dr Sarah L.Co-Founder, Genomics Startup, Cambridge Biomedical Campus“I contract at Arm Holdings and my previous accountant had never done a proper IR35 review. Hayes reviewed my contract, confirmed I was outside IR35, saved my limited company structure, and I’m now keeping around £7,500 more per year. They know Cambridge tech contracting inside out.”
Tom F.Software Contractor, Arm Holdings Cambridge“We have a Fenland arable farm near Ely and Hayes sorted our APR position for the first time in twenty years. They restructured how we hold the land, ensured full agricultural relief applies, and did our annual accounts at a fraction of what we’d been paying. Hugely professional.”
Robert H.Arable Farmer, Ely, Cambridgeshire
