The cascade

Every collapse takes the subcontractors down with it.

3,827 UK construction firms went insolvent in the twelve months to March 2026. Specialist subs are over half of every monthly count. When a main contractor falls, the supply chain pays.

The Construction Act gives every subcontractor the statutory right to force the cash on a missed notice. Most never use it.

The mechanic

Six statutory steps. One missed notice is all it takes.

The Housing Grants, Construction and Regeneration Act 1996 gives the subcontractor the right to force payment on every missed notice. Register tracks the sequence on every Application for Payment, automatically.

01

You submit an Application for Payment.

The AfP lands with the main contractor on the agreed monthly date.

02

The Clock starts.

The Construction Act timeline begins from the day the application is received.

03

The main contractor must issue a Payment Notice within five days of the due date.

Register reads whatever they send — any contractor, any format — and pulls the Notified Sum and the dates. Nothing is typed twice.

04

If the Payment Notice is missed, they may issue a Pay Less Notice before the final date for payment.

Reducing the sum, with the basis for the reduction stated.

05

If both deadlines pass without a notice, the entitlement crystallises.

The applied-for sum becomes the Notified Sum under section 111 of the Act. The main contractor must pay it.

06

Register drafts the Construction Act demand letter. Dated, signed, admissible.

The principle is Macob v Morrison [1999] EWHC 254 (TCC) — pay now, argue later. The adjudicator’s decision is binding within twenty-eight days.

The law is moving

Three regulatory acts. One direction.

Parliament is closing the door on late payment in construction. Register is built around the mechanics already in force, and ready for the mechanics coming next.

Commercial Payments Bill (HL Bill 4)

Introduced into the House of Lords by Lord Leong. A two-year transition followed by a full ban on retention clauses under a new section 113C of the Housing Grants, Construction and Regeneration Act 1996. Existing retention is reclassified as transitional retained sums with statutory deadlines.

Procurement Act 2023, section 73

Live. Forces 30-day payment terms through every tier of public-sector subcontracts. The first Payments Compliance Notice reporting period closed in March 2026.

King's Speech 2026

Confirmed the government's late-payment and retention construction reform package. The package is the policy basis for the Commercial Payments Bill.

The retention float held against the UK subcontractor base sits between £3.2bn and £5.9bn at any time. The Commercial Payments Bill ends it. The Procurement Act tightens the cycle on every public-sector pound. Register is built for both — Construction Act mechanics today, retention release tracking through the transition, statutory interest on every late payment.

Register

The next missed deadline is the one we draft the letter for.

Register tracks every Application for Payment and every Construction Act deadline, and drafts the demand letter the moment one lapses. Early access is opening to UK specialist subcontractors.
