ICAEW has developed guidance for practice firms on what to include in engagement letters. This page provides a series of sample wordings to help you draft your own engagement letters.

Issuing an engagement letter?

If you are issuing a letter of engagement, consider carefully whether you need a practising certificate. Practising without a practising certificate in the UK or the rest of the EEA can result in disciplinary action. Find out more about the requirements and the key matters you need to consider when setting up in practice.

This helpsheet has been issued by ICAEW’s Technical Advisory Service to help ICAEW members in practice when preparing an engagement letter for their services to a client.

This helpsheet explains the importance of considering the various areas of the relationship between advisors and their clients and issuing engagement letters with a view to safeguarding against risks that might arise. To help members put in place appropriate terms of engagement, it provides a series of sample wordings for a variety of typical engagements for both corporate and non-corporate clients. The helpsheet brings together more typical engagements to encourage a consistency of approach when dealing with engagement letters and to help members manage associated risk.

The helpsheet provides best practice guidance. It does not constitute a professional standard. Given that the type of service provided and the nature of client will vary from engagement to engagement, professional judgement should be used in applying this helpsheet and the example wording for engagement letters needs to be tailored to reflect individual situations. The helpsheet is not intended to provide comprehensive advice for the preparation of engagement letters and you should refer to additional sources of information where appropriate, including legal advice if necessary.

The full engagement letter helpsheet

The engagement letter helpsheet is separated into several parts that together will comprise a complete engagement letter.

A complete engagement letter will comprise:

  • an engagement letter (Part 1)
  • schedules of the service(s) to be provided (Part 2)
  • terms of business (Part 4)
  • privacy notices (Part 5)

The individual parts,including the guidance notes for Part 2J, are also available as separate downloads.

You are advised to read the related guidance which is an important part of the helpsheet. 

Separate engagement letter schedule sample wordings

A complete engagement letter will comprise:

  • an engagement letter (Part 1)
  • schedules of the service(s) to be provided (Part 2)
  • terms of business (Part 4)
  • privacy notices (Part 5)

Part 1 of this helpsheet provides draft text of an engagement letter for services provided to individuals, unincorporated businesses, partnerships, limited companies registered under the Companies Act, and limited liability partnerships.

Part 2 provides schedules covering auditing, accounting, taxation and probate work. Additional schedules can be added to cover other services you provide.

Download individual schedules:

Part 3 includes some additional wording that can be used to develop additional schedules, have limited applicability or are alternative clauses.

Part 4 sets out example terms of business (including GDPR clauses for data controllers) which are referred to in the example engagement letter wording. Where a firm has terms of business, they should always accompany and be incorporated into the engagement letter. Provision has been made for dating the terms of business so that it is clear which terms of business have been applied, as they may be updated from time to time.

Part 5 includes a short form template privacy notice which has been drafted on the basis that you/your firm will be collecting certain personal data (such as name and contact details) for the purpose of supplying your products and/or services; communicating with your clients in relation to those products and/or services; and undertaking marketing in relation to the products and services.
