How do we help London companies find an R&D tax specialist?

We help London companies by matching them, free, with an R&D tax specialist or R&D tax consultant from our panel whose sector experience fits the work. You complete one short form, we check the basics such as your claim notification deadline, and with your consent we introduce up to 3 firms. Panel firms work with clients remotely and visit sites where the technical story needs it, so you are not limited to advisers with an office on your street.

Why is London the largest R&D claiming region?

London is the largest claiming region because it hosts a dense mix of software, financial technology, AI and life sciences companies, and many groups have their registered office in the capital even when R&D happens elsewhere. HMRC's figures are by registered office, so some London claims cover work done across the UK. That matters for your claim too: if your team is split across sites, the specialist needs to understand where the work was done and by whom.

Are R&D tax consultants in London different from specialists?

No. London firms use both titles for the same work: identifying qualifying projects, measuring costs, writing the technical report and defending the claim. Judge an R&D tax consultant in London on the same things as any specialist: technical people who understand your field, HMRC registration, insurance and written fees.

Which London sectors make R&D claims?

London's R&D clusters include:

  • King's Cross Knowledge Quarter (N1C, NW1): home to the Francis Crick Institute and major AI research teams, with a strong concentration of life sciences and machine learning companies.
  • Shoreditch, Old Street and Clerkenwell (EC1, EC2, E1): the long-standing base for London software, SaaS and digital product companies.
  • The City and Canary Wharf (EC2, EC3, E14): fintech, payments, trading infrastructure and cybersecurity, where claims often centre on latency, security and data processing.
  • White City (W12): Imperial College London's innovation district, with biotech, engineering and materials spin-outs.
  • Queen Elizabeth Olympic Park (E20): Here East and university campuses with robotics, mobility and creative technology work.

London life sciences companies are often loss-making and research heavy, so ERIS is worth checking. For fintech and SaaS, the key question is usually whether the work went beyond standard development. See our software and AI guide and life sciences guide.

Where is our London office?

Our London office is at Canary Wharf, London E14 3QS. The quickest way to reach us is the enquiry form.

What should London companies check before claiming?

  • Your accounting period end date, and whether a claim notification form is due within six months of it
  • Whether you are an SME and whether ERIS could apply because R&D is 30% or more of total spending
  • Any grants received for the same projects
  • Whether any contractors or externally provided workers were outside the UK, which since April 2024 usually rules their costs out
  • That whoever prepares your claim is registered with HMRC as a tax adviser and puts fees in writing

What do London R&D projects typically look like?

London projects are often software and data heavy, but the strongest claims come from a clear technical problem rather than a new product. Typical examples we see described include:

  • Fintech and trading: building systems that process transactions or market data with lower latency or higher reliability than established architectures allowed.
  • Cybersecurity: new detection or encryption methods that go beyond published techniques.
  • AI start-ups: developing training or inference methods for problems where existing models failed, rather than wrapping a commercial model.
  • Life sciences: assay development, computational biology and drug discovery platforms, often in loss-making companies that may qualify for ERIS.
  • Visual effects and games: new rendering, simulation or engine technology. Creative content itself does not qualify for R&D relief.

R&D relief or creative industry reliefs?

Many London studios can claim creative industry reliefs, such as the audio-visual and video games expenditure credits, for producing content. These are separate from R&D relief and the same costs cannot be claimed twice. Where a studio develops genuinely new technology, such as a rendering engine, that work may qualify for R&D relief instead. A specialist will decide which relief each cost belongs to.

Why do London claims attract scrutiny?

London claims account for 30% of the value of UK R&D relief by registered office, and they include many software and fintech claims, where the line between routine development and R&D is hardest to see. Expect HMRC to ask for a clear baseline and evidence of what was technically uncertain. Claims built from engineers' own records, such as design documents and experiment logs, stand up best.

Frequently asked questions

Do you have an office in London?

Yes. Our office is at Canary Wharf, London E14 3QS. Most enquiries are handled through our online form, and introductions are made to panel firms that work with London clients.

Do I need a London based R&D tax specialist?

Not necessarily. Most claim work is done remotely, and the rules are the same across the UK. Sector knowledge matters more than an office in London.

Are London fintech projects eligible for R&D relief?

Some are. Fintech work qualifies where it resolves technological uncertainty, such as new methods for latency, security or data processing, not where it applies existing technology to a financial product.

How quickly can a specialist start on a London claim?

That depends on the firm's workload and your records. If a deadline is close, say so on the form and we will flag it.

Do many London claims get checked by HMRC?

HMRC does not publish check rates by region. London has the largest share of claims by value, and software and fintech claims attract scrutiny, so strong evidence matters.

Can a London holding company claim for R&D done elsewhere?

Each company claims for its own R&D. HMRC statistics are by registered office, so a London registered company may claim for R&D its staff do anywhere.
