Sub-contracting in construction

It is very common for sub-contractors to be engaged by the main contractor on a construction project. Unless the contractor has itself been appointed for specialist skills or qualities where sub-contracting would not be permitted, it is standard in the market for the contractor to consider which packages of works to sub-contract out to specialist sub-contractors when it becomes involved in a project—and in fact it may sub-contract all of the works. See Practice Note: Sub-contracting in construction projects which also explains the difference between domestic 'nominated' sub-contractors and 'named' sub-contractors, and looks at sub-contracting under the various standard form construction contracts.

Typically, the contractor will enter into a direct sub-contract with each sub-contractor for them to carry out, for an agreed sum, a portion of the obligations that the contractor has taken on under its building contract with the employer. Usually the contractor remains fully responsible to its employer for the works carried out by its sub-contractors and therefore is liable for any default by a sub-contractor.

From the contractor's perspective, it needs to ensure that it has passed down all the relevant obligations

CLC Material Supply Chain Group warns of construction sector decline

The Construction Leadership Council’s (CLC) Material Supply Chain Group ('the Group') has reported that the UK construction market faces persistently weak prospects in early 2026 and warned that urgent demand-side intervention is required to prevent longer-term damage. The Group noted a sharp fall in construction output in the final quarter of 2025, despite modest growth in the wider economy, with concrete volumes down substantially over recent years, particularly in London, indicating a prolonged contraction in activity. While material availability is not constrained and supply generally exceeds demand, manufacturers are holding high stock levels, reassessing production, and, in some cases, mothballing capacity or reducing investment, which would limit the speed of any future recovery.

The Planning and Infrastructure Act 2025-implications for the energy sector

Energy analysis: The Planning and Infrastructure Act 2025 (PIA 2025), which received Royal Assent on 18 December 2025, introduces wide-ranging planning reforms across the UK economy. While the PIA 2025 impacts a range of sectors and industries, it includes specific provisions that affect the energy sector.

No Variations by management—The Privy Council on lump sum risk and claims discipline under FIDIC Yellow Book (UBC v The Water and Sewerage Authority of Trinidad and Tobago)

Construction analysis: The Privy Council dismissed a contractor’s claim, confirming that work expressly or impliedly included within a FIDIC Yellow Book lump sum cannot constitute a variation and that compliance with the clause 20.1 28-day notice requirement for claims is a condition precedent to additional payment. The Privy Council held that all claimed variations fell within the contractor’s design responsibility and the contract specifications, with clauses 4.10 and 4.11 allocating site condition and price sufficiency risk to the contractor. The claims also failed for procedural non-compliance, as no timely clause 20.1 notice was given, and waiver or estoppel arguments were rejected because the Engineer lacked authority to amend contractual obligations and agreed formalities could not be displaced.

Construction industry bodies welcome government Warm Homes Plan but raise implementation concerns

The Chartered Institute of Building (CIOB) and the Federation of Master Builders (FMB) have welcomed the UK government’s Warm Homes Plan, which sets out measures to improve energy efficiency across the housing stock, reduce household energy bills and support the transition to low-carbon homes. It includes a £15bn commitment to upgrade up to five million homes by 2030. CIOB said large-scale energy efficiency improvements are vital for meeting net zero goals and reducing costs for consumers. It warned, however, that success depends on sustained investment in skills and training, a competent workforce and close engagement with the construction sector. Without this, CIOB noted, poor‑quality installations and low consumer confidence could repeat mistakes seen in past stop‑start schemes.
