Yes. Crypto accounting is listed as a specialist service at Edward Harris precisely because it requires a different approach to a standard capital gains calculation. HMRC treats each disposal, each staking reward, and each DeFi interaction differently. You will not need to explain how an exchange settlement works before the conversation becomes useful.

Pricing depends on the volume and complexity of transactions — a handful of straightforward Bitcoin disposals is different from several years of active DeFi activity across multiple chains. The initial conversation is free, and a fixed fee is agreed before any work begins. There are no hourly surprises.

This is a common starting point, not an obstacle. Where transaction histories are missing, HMRC expects a reasonable methodology and clear documentation of the approach taken. We work with whatever records are available, reconstruct where possible, and prepare a voluntary disclosure for prior years if needed. Starting is better than waiting.

No. There is no minimum term. If it is not working after a few months, you leave with your records in order and nothing owed beyond work completed. Most clients stay because the service is useful, not because they are contractually obliged to.

Possibly. HMRC has received data from UK-regulated exchanges under domestic reporting requirements and participates in the Crypto Asset Reporting Framework internationally. Assuming HMRC has no visibility is not a safe position. A voluntary disclosure made before HMRC enquires is treated considerably more favourably than one made after.

Yes. Losses from disposals can be offset against gains in the same year or carried forward to future years — but only if they are formally reported to HMRC, which many people do not do. Timing of disposals relative to the tax year, use of the annual CGT exempt amount, and spousal transfers are all worth considering before the end of the tax year, not after.
