Completion: The Contractor shall achieve practical completion of the Works on or about 15 July 2026.
The Completion Date may be extended by written agreement between the parties where completion is or is likely to be delayed for reasons beyond the Contractor's reasonable control, including (without limitation) exceptionally adverse weather, force majeure, variations instructed by the Client, delay by the Client or its other contractors, or any matter amounting to prevention by the Client. The Contractor shall notify the Client in writing of any circumstance likely to cause delay as soon as reasonably practicable after it becomes apparent, together with the anticipated length of delay and any mitigation proposed.
Payment Stages:
(a) Deposit / first stage: 20% (approx. 5,600 GBP), payable on execution of this Contract and before commencement of the Works;
(b) Interim stage: 50% (approx. 14,000 GBP), payable on the written certification of the agreed interim milestone;

Payment Notices (s.110A HGCRA): Not later than five days after the due date, the Client shall give notice specifying the sum considered due and the basis of calculation. If no such notice is given, the sum notified in the Contractor's application shall become the notified sum.
Final Date for Payment (s.110 HGCRA): The final date for payment of each notified sum is 14 days after the due date.
Pay-Less Notice (s.111 HGCRA): If the Client intends to pay less than the notified sum, the Client must give a written pay-less notice not later than 5 days before the final date for payment, specifying the sum the Client considers to be due and the basis of calculation. In the absence of a compliant pay-less notice, the Client shall pay the notified sum in full.
Suspension for non-payment (s.112 HGCRA): If any notified sum is not paid in full by the final date for payment and no valid pay-less notice has been served, the Contractor may, on seven days' written notice, suspend performance of any or all of its obligations under this Contract until payment is made. The Contractor shall be entitled to an extension of time and to reasonable costs and expenses incurred as a result of the suspension (s.112(3A) HGCRA).
Pay-when-paid prohibited (s.113 HGCRA): Any provision in this Contract making payment conditional on the Client or Contractor receiving payment from a third party is ineffective, except where that third party is insolvent as defined in s.113(2)-(4).
The Contractor shall comply with the Health and Safety at Work etc Act 1974, the Management of Health and Safety at Work Regulations 1999, the Work at Height Regulations 2005, the Control of Substances Hazardous to Health Regulations 2002 and all other relevant statutory provisions. The Contractor shall produce evidence of its compliance (including risk assessments, method statements, safe systems of work and F10 notification where required) on request.
(b) Amendments: No amendment to this Contract is effective unless made in writing and signed by or on behalf of both parties.
(c) Severability: If any provision is held to be unenforceable, the remaining provisions shall continue in full force.

(e) Notices: Notices under this Contract shall be in writing and served at the address given on the first page, by hand, first-class post or email (with confirmation of receipt). Service provisions comply with section 115 HGCRA 1996.
What Is a Building Contract?
A building contract is a legally binding agreement between a client (the employer) and a contractor for the execution of construction works. It defines the scope of work, the contract price, the programme, quality standards and the rights and obligations of both parties.
In England and Wales, building contracts are governed by general contract law principles supplemented by specific construction legislation, including the Housing Grants, Construction and Regeneration Act 1996 (as amended by the Local Democracy, Economic Development and Construction Act 2009) and the Building Safety Act 2022.
While UK industry standard forms such as JCT and NEC are widely used for larger British projects, a bespoke building contract is suitable for smaller domestic and commercial works in England and Wales. It ensures both parties understand their obligations under English law and provides a framework for managing disputes.

Construction Act Requirements
The UK Housing Grants, Construction and Regeneration Act 1996 (as amended) applies to most British construction contracts. It provides statutory rights to interim payments, a proper payment mechanism with payment and pay less notices, and the right to adjudicate disputes at any time in England and Wales. Contracts that do not comply are supplemented by the UK Scheme for Construction Contracts.
Building Regulations Compliance
All building work in the United Kingdom must comply with the Building Regulations 2010 (as amended). The British contractor is responsible for ensuring the works meet the applicable requirements. Building control approval or certification by an approved inspector must be obtained under English law. The UK Building Safety Act 2022 introduced additional requirements for higher-risk buildings.
CDM Regulations
The UK Construction (Design and Management) Regulations 2015 apply to all construction projects in Britain. For domestic clients, the contractor or principal contractor assumes the client’s duties unless a written agreement states otherwise. Health and safety planning, competent appointments and proper welfare facilities are required under British regulations.
Limitation Periods
Claims for breach of a simple UK building contract must be brought within six years under the Limitation Act 1980. If the British contract is executed as a deed, the limitation period extends to twelve years under English law. Defects claims relating to the building’s structural integrity may also arise under the UK Defective Premises Act 1972.
