Summary of the contracting process

Karbon Homes procured window-cleaning services for its residential communal properties, offices and other premises used by staff, customers or the public. The contractor is responsible for cleaning accessible windows and associated glass surfaces, supplying labour, equipment and cleaning materials, and using suitable methods such as water-fed poles where applicable. A detailed property schedule is to set out locations, cleaning frequencies and site-specific requirements, with delivery expected to adapt to operational needs. The work covers three geographic areas: Northumberland; Newcastle, Leazes and North Tyneside; and Durham, Gateshead, South Tyne and Teesside. This is a building and window-cleaning service (CPV 90911000), commissioned by Karbon Homes across its property portfolio.

The procurement is complete: Karbon Homes awarded all three lots to Lees Cleaning Contractors LLP, and the contract was signed on 29 September 2026. The award date was 14 September 2026. The awarded gross value is £557,920.51 for the combined contract. The contract runs from 1 April 2027 to 31 March 2029, with two optional 12-month extensions, potentially extending the period to 31 March 2031. The open procedure used separate lot evaluations. Each lot was assessed on price (45%), quality (45%) and social value (10%). The original estimated gross lot values were £80,000 for Northumberland, £220,000 for Newcastle, Leazes and North Tyneside, and £150,000 for Durham, Gateshead, South Tyne and Teesside. Five bids were received for each of the first two lots and seven for the third.

This award shows that Karbon Homes buys a geographically broad, multi-site window-cleaning service across communal residential buildings, offices and other public-facing premises. A credible future competitor would need the operational capacity to cover the relevant areas, plan work against a property-by-property schedule, and respond flexibly when requirements change. The scope calls for competent window cleaners, suitable equipment and materials, and the ability to use water-fed pole systems where appropriate. Contractors should be able to evidence reliable delivery and strong service quality, while also presenting a persuasive social-value offer: these formed the non-price elements of the evaluation. The work was divided into three independently evaluated areas, making the requirement relevant to both regional specialists and suppliers able to manage delivery across several areas. The appointed supplier is an SME, and SMEs were considered suitable for all three lots.
