This is informational screening, not tax advice
R&D Radar applies the UK DSIT Guidelines (the meaning of R&D for tax purposes) to the description you provide, and drafts supporting material: a verdict, a narrative in the shape of HMRC's Additional Information Form, an evidence list and, in the claim pack, a cost schedule and an estimate of relief. It does not provide tax, legal or accounting advice; it does not file claims or correspond with HMRC on your behalf; and a “likely” verdict or an estimate is not a guarantee that a claim will succeed or that HMRC will pay a particular amount. Everything it produces is a draft for you and your accountant to check, correct and take responsibility for before filing.
Your responsibilities
Verdicts are only as good as what you tell us. You're responsible for the accuracy of the descriptions and answers you submit, and for ensuring you have the right to share them. The service is intended for UK limited companies considering Corporation Tax R&D relief. If you use anything R&D Radar produces in a claim, HMRC's Additional Information Form asks you to list every agent involved, including anyone who helped prepare technical assessments or analysed costs — list R&D Radar there.
Paid packs
Screening and the verdict are free within the fair-use limit. The narrative pack and the claim pack are one-off purchases for a single screening, priced in pounds sterling as shown on the page at the time you buy; prices are stated inclusive of any UK VAT due. Payment is taken by card through Stripe; we never see or store your card details. A pack is delivered instantly on payment and stays available on your account. If you buy the narrative pack first, upgrading to the claim pack costs the difference.
Because a pack is digital content delivered immediately, your right to cancel ends when it is delivered. If a pack is materially defective — it will not open, or does not contain what the page promised — email us within 14 days and we will fix it or refund it. Prices and pack contents may change; a change never affects a pack you have already bought.
Estimates and cost figures
The cost template totals the figures you enter and applies the headline relief rate for the scheme and period you select. It is an estimate using simplified rules. It does not model every restriction (for example grant-funded spend, connected subcontractors, the PAYE cap or overseas work); the caveats on the page list the ones most likely to apply. Your accountant must confirm the figures before they go on a return.
Fair use
Free screenings are for genuine use. We may throttle or suspend accounts that abuse the service (automated scraping, bulk screening for resale, attempting to circumvent limits).
No warranty; limitation of liability
The service is provided “as is”, without warranties of any kind beyond those stated above for paid packs. To the maximum extent permitted by law, we accept no liability for losses arising from use of the service, including decisions made or claims filed on the basis of its output. Where liability cannot be excluded, it is limited to the amount you paid us for the pack concerned. Nothing in these terms limits liability that cannot be limited by law.
Changes
We may update the service and these terms as the product develops; material changes will be shown here with a new date. Questions? Email hello@rd-radar.com.
