Construction disputes often turn on the contract wording, project records, notices and expert evidence. Our construction dispute solicitors assess those issues early, including entitlement under JCT, NEC and bespoke contracts, the operation of payment mechanisms and the strength of any delay, defect or valuation claim.
We also advise on the most appropriate forum for resolving the dispute, whether through adjudication, mediation, arbitration or proceedings in the Technology and Construction Court.
Where specialist evidence is required, we work with leading barristers, delay experts, quantity surveyors, engineers and other construction professionals to build or defend the claim.
Barnes Law is recognised by the leading directory Chambers & Partners, reflecting our experience advising businesses on major disputes.
Our construction dispute lawyers advise on claims arising throughout the lifecycle of construction and engineering projects, from construction contract formation and payment to completion, defects and termination.
Our construction dispute lawyers advise on claims arising throughout the lifecycle of construction and engineering projects, from contract formation and payment to completion, defects and termination.
We advise on claims for extensions of time, prolongation, disruption and loss and expense. These disputes often turn on critical path analysis, contemporaneous project records, contractual notice requirements and the allocation of responsibility for delay.
We act in disputes concerning interim payments, final accounts, payment notices, pay less notices, retention and valuation. Our construction dispute solicitors also advise on the payment regime under the Housing Grants, Construction and Regeneration Act 1996 and related adjudication rights.
We advise on claims involving defective design, workmanship and materials, including disputes over remedial works, responsibility for defects and the cost of putting work right. These claims can involve contractors, subcontractors and construction professionals.
Disputes frequently arise over whether work falls within the original scope, whether a valid variation has been instructed and how additional work should be valued. We advise on variation claims under JCT, NEC and bespoke construction contracts.
We advise employers and contractors on contractual termination, repudiatory breach, suspension and the consequences of bringing works to an end. These disputes often involve payment, loss of profit, completion costs and the validity of contractual notices.
We advise on claims against architects, engineers, surveyors, project managers and other construction professionals where negligent advice, design or supervision has caused loss. We work closely on these matters with our professional negligence claims team.
Adjudication provides a fast-track process for resolving construction disputes and is widely used for payment, valuation, delay and defect claims. Our construction dispute solicitors advise on adjudication notices, referrals, responses and enforcement of adjudicators’ decisions.
We act in arbitration and proceedings before the Technology and Construction Court, including complex disputes involving expert evidence, contractual interpretation and substantial financial claims. We also advise on dispute resolution proceedings where construction issues form part of a broader commercial dispute.
Review the payment provisions in the contract, including the payment application, payment notice and any pay less notice, and act quickly to preserve your position. Our commercial litigation lawyers advise on unpaid construction sums and enforcement options.
Check whether the pay less notice was served on time and complies with the contractual and statutory requirements. A defective notice can materially affect the amount due and the next steps available in adjudication or court proceedings.
Yes. Adjudication is commonly used to recover unpaid construction sums and can provide a binding decision quickly, subject to later determination by arbitration or the courts.
Document the defects, preserve evidence and obtain appropriate technical advice before remedial work is carried out. Our professional negligence team also advises where defective work results from negligent design, specification or supervision by construction professionals.
Yes. Termination rights depend on the contract and the nature of the breach, so the notice and termination procedure must be followed carefully. Wrongful termination can itself give rise to substantial claims.
Yes. Depending on the contract and cause of delay, a party can claim extensions of time, loss and expense, prolongation costs or damages. These claims often require detailed project records and expert evidence.
Review the termination and step-in provisions immediately, secure the site and preserve records of the work completed, defects and additional completion costs. Our commercial law team can advise on the underlying contractual rights and obligations, and our real estate solicitors are also able to help where the dispute affects the ownership, development, occupation or value of the property.
Yes. Adjudicators’ decisions are generally enforceable through the Technology and Construction Court, while challenges are limited and usually focus on jurisdiction or serious procedural unfairness. Our arbitration lawyers in London can help with arbitral proceedings where the contract provides for that route.
