Website and Client Portal Terms

Effective as of 18 September 2026 · Version 2026-09-18

These terms cover using this website and your client account, and what happens to the information you send us so we can scope and quote your work. They do not commission any work. Before we start, we issue an engagement agreement that sets out the services, tax years and fee and incorporates our General Terms of Engagement.

1. Who we are

1.1

BlockBooks is the trading name of BlockBooks Accounting Ltd, a company registered in England and Wales (number 10742413). Our registered office is 167-169 Great Portland Street, London, England, W1W 5PF. Our VAT number is GB301116082. Contact us at [email protected].

1.2

We are a firm of Chartered Accountants regulated by the Institute of Chartered Accountants of Scotland (ICAS), which also supervises our anti-money laundering compliance. We comply with the ICAS Code of Ethics and, when undertaking UK tax work, with Professional Conduct in Relation to Taxation (PCRT). These professional requirements are available at www.icas.com.

1.3

Our professional indemnity insurer is Hiscox Insurance Company Limited, 22 Bishopsgate, London EC2N 4BQ, United Kingdom. Cover applies worldwide, except for claims brought in the courts of the United States of America or Canada. Further details are available on request from [email protected].

2. What this website is

2.1

These terms govern your use of the BlockBooks website and client portal, and the information you send us through them. They apply whether or not you go on to engage us.

2.2

The content of this site, including guides, calculators and quote estimates, is general information. It is not tax, legal or investment advice and does not take account of your circumstances. Do not rely on it as a substitute for advice on your own position.

2.3

Nothing on this site creates an engagement. We act for you only once we have agreed the scope and fee of specific work in writing, in an engagement agreement that incorporates our General Terms of Engagement (published at /terms/engagement). A quote produced on this site is an estimate based on what you tell us. It is not a fixed fee and not an offer capable of acceptance.

3. Your account

3.1

You are responsible for keeping your login details confidential and for activity under your account. Tell us promptly at [email protected] if you believe your account has been accessed without authority.

3.2

Never send us wallet private keys, seed phrases, or Government Gateway or GOV.UK One Login credentials, through the portal or by any other route. We will never ask for them. Where access to a wallet or account is needed we use read-only methods or the authorisation processes the provider offers.

3.3

We may suspend or close an account that is used unlawfully, to disrupt the service, or in breach of these terms.

4. Information you send us for scoping

4.1

Before any engagement, you may send us wallet addresses, exchange statements and other records so that we can assess the work involved and confirm or revise the estimate. Sending this information does not commission any work and does not oblige either of us to proceed.

4.2

We use it only to scope the work, confirm the fee, and carry out any checks we must complete before acting. If we go on to act for you, it becomes part of your engagement.

4.3

Before we start chargeable work we will issue an engagement agreement setting out the services, tax years, fee and any specific arrangements, together with the General Terms of Engagement that will govern the work. Any cancellation rights you have as a consumer arise under that agreement and are explained in it.

4.4

If you decide not to proceed, or we decline to act, we keep the information only for as long as our legal, regulatory and professional obligations require, and then securely delete it.

5. Data protection

5.1

We are the data controller for personal information collected through this site and portal. Our Privacy Policy at /privacy explains what we collect, why, who we share it with, how long we keep it and your rights.

5.2

Where the records you send us contain another person's personal information, you must have a lawful basis to share it with us.

6. Anti-money laundering

6.1

We are supervised for anti-money laundering purposes and must verify the identity of every client before acting. We may ask you to complete an identity check, and to explain the source of funds or wealth, before an engagement is confirmed. We may decline to act if those checks cannot be completed.

6.2

We may be required by law to report knowledge or suspicion of money laundering to the appropriate authority, and may be prohibited from telling you that a report has been made. Those duties apply from first contact and take precedence over any confidentiality obligation.

7. Liability for this pre-engagement stage

7.1

We take reasonable care to keep this site accurate and available, but it is provided without any promise that it is error-free or uninterrupted. To the extent the law permits, we are not liable for loss arising from reliance on general information on this site, or from an estimate that is later confirmed or revised.

7.2

Nothing in these terms excludes or limits liability for death or personal injury caused by negligence, fraud, fraudulent misrepresentation, or any other liability that cannot lawfully be limited. Nothing in these terms restricts your statutory rights as a consumer.

7.3

Our responsibilities and liability for professional services are set out in the General Terms of Engagement and your engagement agreement, not here.

8. Complaints and governing law

8.1

Please raise any concern with Tim Whitehouse at [email protected] or in writing to our registered office. We will investigate fairly and promptly and explain our findings. If the matter remains unresolved, you may refer a complaint about professional conduct to ICAS; information on making a complaint is available at https://www.icas.com/regulation-technical-resources/regulation/complaints-and-sanctions/how-to-make-a-complaint-against-an-icas-member.

8.2

These terms are governed by the law of England and Wales, and its courts have jurisdiction, subject to any mandatory rights you have as a consumer to rely on protections or bring proceedings in the courts of the part of the UK where you live. If a provision is unenforceable, the remaining provisions continue to apply so far as the law permits.

8.3

We may publish a new version of these terms. The version you accepted, and the date and time you accepted it, are recorded. A later version does not change what you agreed to, but we will ask you to accept it before your next submission through this site.
