How to compare R&D tax consultants

The right consultant should protect the claim as well as estimate it. That means technical evidence, cost review, and clear HMRC submission support.

Start with the R&D tax credit calculator if you need a quick claim-value estimate before reading the detail.

Look beyond the headline percentage

A high estimate can be attractive, but the claim still needs to survive questions about eligibility, apportionment, and documentation. Ask how each figure is supported.

Check enquiry support

Find out whether the consultant helps if HMRC opens an enquiry, whether that support is included, and who owns the technical narrative.

Use the calculator first

A rough calculator estimate helps you ask better questions. If the potential benefit is small, a light-touch review may be enough. If it is large, the evidence standard matters more.

Important note

R&D tax relief depends on scheme rules, company facts, accounting periods, and HMRC evidence standards. Treat this page as research support, not tax advice.
