Retention Release Request Letter Template for England and Wales

A retention release letter is your formal tool for recovering retention monies held by employers under construction contracts in England and Wales. This document becomes essential when you've completed your contractual obligations and need to claim funds that were withheld as security during the project. Understanding when and how to use this letter properly can save you time and prevent payment disputes.

What is a retention letter?

A retention letter, in a construction context, is written correspondence about retention monies held back from payments as security for performance. The retention release version is sent by the party that carried out the works to the employer once the conditions for release have been met. It states the project details, the contract date, the clauses relied on, and the exact amount now due, and it asks that the funds be released to a named contact by a specific date.

When do you need this document?

You'll need a retention release letter after reaching practical completion of your construction project and fulfilling the defects liability period requirements. This typically occurs when you've remedied any identified defects and the contract administrator has certified completion. The letter is particularly important when dealing with JCT, NEC, or FIDIC standard form contracts, where retention clauses are standard. You may also use this document to claim early release of the first half of retention upon practical completion, or the final release after the defects liability period expires. If you're facing cash flow pressures or the employer is unreasonably withholding retention despite meeting release conditions, this formal letter establishes your legal position.

What should a retention release letter include?

A complete letter is easier to act on and harder to ignore. Cover the following:

• The date of the letter and the original contract date.
• The project name and, where relevant, the site or plot reference number.
• The specific contract clauses that entitle you to release.
• The exact retention amount being claimed, shown as a figure.
• Evidence of completion status and any completion or making-good certificate.
• A named contact and the payment details for where funds should be sent.
• The date by which you expect the money to be released.

Setting these out clearly means the recipient can verify the claim and process the release without further back-and-forth. For related documents that govern how these payments and retentions are structured, see our service agreement templates.

Key legal considerations

Your letter must clearly reference the specific contract clauses that entitle you to release, typically found in payment and retention provisions of standard forms. Under the Construction Act 1996, you have statutory rights to payment that override contractual terms attempting to delay or prevent legitimate retention release. The letter should specify the exact retention amount, provide evidence of completion status, and reference any relevant certificates or approvals. Retention monies may attract interest under the Late Payment of Commercial Debts (Interest) Act 1998 if wrongfully withheld. Address any outstanding issues that might justify continued retention, demonstrating why these don't prevent release, and consider Construction Industry Scheme implications, as release may trigger tax obligations that need addressing in your correspondence.

How should you send a retention release letter?

Follow the notice and delivery methods your contract specifies. Many standard forms require notices to be sent by post to a stated address, by hand, or by email to a named contact, and some set a required delivery method for it to count as valid service. Keep proof of the date you sent it, whether that's a recorded delivery receipt or a saved email, so there's a clear record if a dispute over timing arises. Send the letter to the correct contact under the contract, usually the employer or the contract administrator, and copy anyone the contract names.

Worked example

Say your contract holds a 5% retention on a build worth £200,000, so £10,000 is held back. Half (£5,000) becomes due at practical completion, the balance once the defects liability period expires. Your letter would name the project, cite the contract date and clause, state the £5,000 or £10,000 figure, attach the making-good certificate, and give a payment date and bank details for the transfer.

Legal requirements in England and Wales

Under the law of England and Wales, your letter must comply with Construction Act 1996 payment provisions and follow contractual notice procedures. The Housing Grants, Construction and Regeneration Act, as amended by the Local Democracy, Economic Development and Construction Act 2009, provides statutory backing for your payment rights. Your letter should serve as formal notice under relevant contract clauses and may constitute the first step in statutory adjudication if release is refused. Ensure compliance with any contractual notice periods and delivery methods. The Limitation Act 1980 gives you six years for simple contracts (twelve years for deeds) to pursue retention claims, but prompt action protects your position. Document everything carefully, as your letter and the date it was sent may become important evidence in any subsequent dispute resolution, whether through adjudication or alternative methods.
