Mid‑sized, innovation‑heavy businesses choose Alexander Clifford when the claim really matters; especially for complex software and engineering projects, or when HMRC is already asking questions.

“My R&D application was complex and difficult to explain to those not working in the industry. Alexander Clifford’s technical and commercial expertise made sure the application was structured in such a way to ensure success.”

- Barry B.

“We switched to Alexander Clifford for our R&D tax credits and the difference was clear straight away. They were much quicker than our previous agency and delivered far better value.”

- Fiona M.

“We had a compliance check from HMRC on our R&D claim, originally handled by another company who weren’t interested in assisting. Alexander Clifford stepped in, rebuilt the claim and guided us to a successful outcome.”

- Sam R.

“The claim was prepared in under 2 weeks and we received the full tax return in 5 weeks. Worth paying a little more for quality work.”

A fast, compliant way to claim R&D tax relief

1

Check eligibility

Share the basics about your projects and R&D spend. We’ll assess them against HMRC’s definition of R&D (advance in science/technology, genuine technical uncertainty, competent professional) and quickly confirm whether it’s worth proceeding.

2

Build a robust claim

We work with your finance and technical leads to identify every qualifying activity and cost (PAYE staff, EPWs, subcontractors, consumables, software, data & cloud). Then we draft the technical narratives and financial breakdown to HMRC’s current standards.

3

Submit & get paid

We prepare the required Additional Information Form and claim paperwork, submit to HMRC and handle questions on your behalf. Many clients receive their benefit in around a month; HMRC’s target is typically 30 days, but timings can vary.

FAQs

Do I need to be profitable to benefit?

Not necessarily. Under the current rules, companies claim a taxable expenditure credit (RDEC) at 20% under the merged scheme, while loss‑making R&D‑intensive SMEs may access enhanced support (ERIS). We’ll advise which route fits you.

What info do you need to submit a claim?
HMRC now requires an Additional Information Form to accompany your R&D claim, covering company details, project descriptions and costs. We prepare this for you.

I’m claiming for the first time - anything special to do?

Some first‑time claimants (or those who haven’t claimed in 3+ years) must pre‑notify HMRC within the “claim notification period”, which starts on day one of your period of account and ends 6 months after it ends. We’ll check if this applies and handle it.

Which costs can I include?

PAYE/staff costs, EPWs, consumables, software, data & cloud, and certain subcontractor costs are typical; rules vary by period and contractual setup. We’ll map everything to HMRC’s current guidance.

How long does it take to be paid?

Timings vary. HMRC aims to pay 85% within 45 days in many cases; some clients are paid in around a month.

Is there a minimum R&D spend you work with?

We’re best suited to companies investing £60k+ per year in qualifying R&D. If your spend is lower, we may still be able to point you towards helpful HMRC resources, but our advisory service is designed for larger, more complex claims.

Ready to see if your R&D qualifies?

If you’re a UK Limited company investing £60k+ in innovation, our specialists can quickly show you whether you’re leaving money on the table and how to claim it safely.
