Summary of the contracting process

Thames Water Utilities Limited is procuring a two-lot framework for sewer rehabilitation, CCTV inspection and sewer cleaning across its operating area in London and South East England. The work covers gravity and rising mains, including structural lining, pipe replacement, patch repairs, leak-tight lining, pipe bursting and manhole sealing. Associated services include minor civil works, inspections and reports, waste disposal and street works. Some projects will involve working on or near railway infrastructure. Lot 1 covers lower-value or non-complex work, while Lot 2 covers higher-value or complex programmes and projects. The framework is intended for suppliers delivering sewerage works, cleaning, surveying and related management services, and companies may apply for one or both lots.

The process has reached tender: Thames Water invited offers through a selective competitive flexible procedure. The procurement uses a closed, multi-supplier framework, with up to six suppliers appointed to each lot. Enquiries had to be submitted by 10 August 2026 at 17:00, and PSQ submissions by 24 August 2026 at 12:00. The award decision is due by 8 March 2027. Each lot is planned to run from 26 April 2027 to 25 April 2030, with extensions allowing a maximum end date of 25 April 2035. Lot 1 is valued at £89,574,389 excluding VAT and Lot 2 at £100,100,000 excluding VAT. Evaluation is 20% safety and environmental, 40% delivery and technical, and 40% commercial rates.

This opportunity suits sewer rehabilitation contractors, sewer inspection and cleaning specialists, civil engineering firms and businesses able to combine these capabilities. Suppliers should be able to deliver lining, replacement, repairs, pipe bursting, CCTV, cleaning, manhole sealing, civil works, reporting, waste disposal and street works across projects of differing scale and complexity. Railway-related work requires the relevant accreditations and insurance levels. Applicants need a minimum annual turnover of £6 million, must pass a financial stability assessment and have the required insurance at award. The framework is identified as suitable for SMEs. Strong bids will demonstrate safety and environmental management, technical delivery capability, and competitive labour, plant, materials and activity rates. Lot 1 uses NEC4 ECSC; Lot 2 uses NEC4 ECC Options B or D.
