Terms of service

Last updated June 2026 · Draft — pending legal review before any real client connection.

This is a working draft and will be finalised with legal review. By using Aven you agree to these terms (UK law).

What Aven does

Aven assembles AIF-aligned, enquiry-ready R&D evidence and drafts narratives that are reviewed by a competent person before delivery.

What Aven does not do

Aven does notfile claims with HMRC, determine your tax liability, select your scheme, sequence loss relief, or guarantee any amount or outcome. Scheme selection and strategy are your accountant or tax firm’s responsibility. Nothing Aven provides is tax advice.

Indicative figures

Any ranges or estimates shown are indicative only, deliberately conservative, and must be confirmed by your reviewing tax firm.

Reviews & refunds

Every pack passes a competent-professional review before delivery. Where the evidence cannot support a defensible pack, we will tell you and will not deliver one.
