Lee Valley Heat Network Operating Company Limited, trading as Energetik, intends to award a contract worth 12,162,500.76 pounds excluding value added tax to Proven Project (District Heating) Ltd for two extensions to the Meridian Water Heat Network in Enfield. The contract award notice, identifier 082224-2026, was published on the United Kingdom tender service at 14:23 on 28 August 2026. The gross figure is 14,595,000.91 pounds.

The award is recorded as pending. A mandatory standstill period of eight working days under section 51 of the Procurement Act 2023 began on the day the notice was published.

Liquidated damages are set at 20,000 pounds per day if the sectional completion date of 31 March 2027 or practical completion by 31 March 2028 are not achieved. The buyer states the reason: the project is grant funded and the grant is lost if contract spend does not reach certain minimum thresholds each financial year.

The two extensions

The contract covers the design and construction of a northern extension and a western extension to the Meridian Water Heat Network. The western extension runs from Church Street near Edmonton Green to Winchmore School and Edmonton County school at its Bury Campus. The northern extension runs from Ponders End High Street near Ponders End Park to Capital College and Waverley School.

The scope also includes extending the existing leak detection system on the network, cleaning the pipe installed, hydraulically testing it with treated water to the same standard as the existing network, and commissioning the extensions to provide heat on to the extended system.

The programme, and what governs it

Pre-construction work is due to start on contract award, on or before 22 September 2026. Alongside the ordinary pre-construction obligations, the buyer will permit further ground penetrating radar work, design and trial holes during that period. Construction is expected to begin on or before 5 January 2027, following a successful planning application by the employer and subject to the contractor agreeing section 50 licences with the highway authority.

The contract is expected to run for approximately 18 months. The buyer names the JCT Major Construction Contract 2024 edition as the contract terms, with the completion date as stated in the contract particulars or fixed from time to time under clause 18, extension of time.

That combination is worth reading together. A contractor is being asked to hit a sectional date on 31 March 2027 and practical completion on 31 March 2028, with 20,000 pounds a day at stake, on a start that is conditional on the employer obtaining planning permission and on the contractor obtaining street works licences from a third party. The extension of time machinery in the named form is where those conditions will be argued if either slips.

Street works are the critical constraint

The buyer is unusually direct about where the difficulty lies. It states that what the project succeeds or fails on is liaison with the highway authority team, and the development of a route design and traffic management proposals that permit the granting of section 50 licences for the works.

Two operational limits follow. Full road closures are highly unlikely to be permitted. Multiple gangs will only be permitted where they do not cause undue disruption to commuters and businesses on the borough's roads. A contractor pricing an 18 month programme against a fixed grant deadline therefore cannot assume it can add labour to recover time, because the permission to work multiple fronts is not the contractor's to give.

Section 50 licence fees, deposits and bonds will be paid by the employer to the highway authority, so that cost sits on the employer's side of the line rather than the contractor's.

The award follows a one stage open procedure under the Procurement Act 2023, advertised on 19 March 2026 under tender notice identifier 20260722-000001. The London Borough of Enfield, Therma Mech Limited and OCU Utility Services Ltd are recorded as parties on the notice alongside the buyer and the successful contractor.

The commercial shape here repays attention from anyone bidding grant funded heat network work. The employer has taken the planning risk and the licence cost, and has kept the programme risk on the contractor with damages sized to the grant rather than to its own loss. That is a defensible position when the grant genuinely disappears at a financial year end, and it is the kind of allocation that only holds if the employer delivers its own conditions precedent on time.
