Adam Bernard Solicitors advises developers, main contractors, subcontractors and consultants across London on contracts that keep projects moving and cash flowing. Construction is one of the most heavily regulated contract environments in the UK. Statute controls how and when you get paid, how disputes are resolved and who is responsible for building safety, so the contract has to work with the law, not against it.

What Should a Subcontractor Agreement Include?

A subcontractor agreement should set out the scope of works, price, payment mechanism, programme, variations, retention, insurance, health and safety duties and dispute resolution. In particular:

  • Aclear scope and drawings or specification, so variations can be identified and 
  • Paymentapplication and notice dates that comply with the Construction 
  • Retention percentage and release
  • Liabilitycaps, liquidated damages for delay and defects 
  • Healthand safety duties under the Construction (Design and Management) Regulations 2015.

The Construction Act: Understanding Your Statutory Payment Rights

Under Part II of the Housing Grants, Construction and Regeneration Act 1996, most construction contracts must include an adequate payment mechanism and a right to refer disputes to adjudication at any time. Key rules in Part II of the Act include:

  • Interimpayments for contracts lasting 45 days or 
  • Paymentnotices and pay less notices setting out the sum due and any amount to be
  • Aban on pay-when-paid clauses, except in limited insolvency 
  • Aright to suspend performance for non-payment, after 
  • Adjudicationas a fast dispute resolution route, with decisions binding until finally 

If a contract does not comply, the Scheme for Construction Contracts (England and Wales) Regulations 1998 fills the gaps. Many disputes arise because parties assume they can contract out of these rules when they cannot.

Building Safety Act Duties in Construction Contracts

The Building Safety Act 2022 created new dutyholder responsibilities and longer liability periods that construction contracts now need to address. The Building Safety Act 2022 introduced a stricter regime for higher-risk buildings and extended limitation periods for certain claims under the Defective Premises Act 1972. Contracts should clearly allocate design and building regulation compliance responsibilities, and require the information needed for the golden thread of building information.

Late Payment in Construction

Construction businesses can also claim statutory interest on late commercial payments. The Late Payment of Commercial Debts (Interest) Act 1998 gives a statutory right to interest and fixed compensation where a contract does not provide a substantial alternative remedy. GOV.UK explains how late payment interest works.

  • Defectivework and responsibility for remedial

Construction Contract Checklist Before You Sign

Before signing any construction contract or subcontract, check five things: scope, payment, delay, design responsibility and exit.

  • Scope– are the drawings, specification and exclusions complete?
  • Payment–are the application, due date, final date for payment and notice requirements clear and compliant with the Construction Act?
  • Delay–what are the liquidated damages, and what events entitle you to an extension of time?
  • Designresponsibility –are you taking on design liability, and is it insured?
  • Exit– what are the termination rights, and how is the final account valued?

A short review at this stage, through our contract review service, costs a fraction of an adjudication.

Frequently Asked Questions

Can a construction contract include a pay-when-paid clause?

Generally no. Part II of the Housing Grants, Construction and Regeneration Act 1996 makes pay-when-paid clauses ineffective in most construction contracts, except where a third party up the payment chain becomes insolvent.

What is construction adjudication?

Adjudication is a statutory dispute resolution process under the Construction Act. Either party can refer a dispute at any time, and the adjudicator's decision is binding until the dispute is finally decided by a court, arbitration or agreement.

What happens if my construction contract does not have compliant payment terms?

The Scheme for Construction Contracts (England and Wales) Regulations 1998 implies statutory payment and adjudication provisions into the contract to fill the gaps.

Do construction contracts need to address the Building Safety Act 2022?

Yes. Contracts should allocate dutyholder responsibilities, building regulation compliance and information obligations, particularly for higher-risk buildings, and reflect extended limitation periods for certain defects claims.

Do you review JCT or NEC contracts?

Yes. We review standard form contracts and prepare schedules of amendments so the standard terms reflect your project and risk position.
