Work will take place across the East Midlands, West Midlands, South East and South West of England. The opportunity is relevant to contractors that can provide end-to-end radon assessment services for residential property portfolios, including field installation and monitoring, technical analysis, interpretation of findings, advice on remedial action and clear reporting for the client.

The award decision was scheduled for 18 November 2026. Evaluation is weighted 65% quality, 30% pricing and 5% social value. Electronic submission is allowed, in English, through the GreenSquareAccord In-tend supplier portal, following registration and mandatory document uploads. This opportunity suits specialist radon testing, surveying and environmental monitoring companies, including small and medium-sized enterprises. Suppliers need the technical capability to deploy and manage radon monitoring devices across a dispersed housing portfolio, undertake reliable surveys, analyse monitoring data and explain the implications of results. They must also be able to provide specialist advice and reporting that GreenSquareAccord can use to understand risks and determine appropriate responses. Delivery requires suppliers to provide their own labour, equipment and technical expertise, so bidders should have the operational capacity to coordinate fieldwork across four English regions and maintain consistent service standards. The quality weighting makes technical approach and service delivery capability particularly important, while social value and competitive pricing also contribute to the evaluation. ## Notice This procurement activity is to appoint a specialist supplier to deliver radon monitoring and surveying services across GreenSquareAccord properties.
