Why is a letter of engagement important?
Using a formal letter of engagement ensures that both you and your client have a shared understanding of the work to be performed, the fees involved, and the legal responsibilities of each party. This reduces the risk of disputes and scope creep.
How to customise this template?
Open the template and replace the bracketed placeholders like [Client Name] and [Firm Name] with the relevant details. Ensure you review the legal clauses to match your firm's specific terms and conditions.

Frequently asked questions
Is this template legally binding?
While this template covers standard professional requirements, it should be reviewed by your legal counsel to ensure it meets your specific firm needs and current legislation.
Can I use this for all clients?

How often should I update it?
We recommend a full review of your engagement documents at least annually or when professional body guidance changes.
Is a digital signature sufficient?

Why tracking leads and proposals matters
Every enquiry a practice fails to follow up is lost fee income. A clear pipeline shows which prospects need a reply, a proposal or a follow-up.
Faster replies
Prospects often contact more than one firm, so the firm that replies first and clearly has an advantage.
Consistent proposals
Templates and a services catalogue keep scope and pricing consistent whoever writes the proposal.
Signed terms from day one
E-signed engagement letters confirm scope and responsibilities before work begins.
No re-keying
Converting a won lead into a client keeps the details you already collected.
Practical tips from UK practice
- Reply to every new enquiry within one working day.
- Use lead statuses that match your real sales stages, and review them weekly.
- Send the engagement letter with the proposal so the client signs once.
- Record why lost leads were lost, to improve pricing and messaging.
