Summary of the contracting process

Flintshire County Council is procuring whole-house energy-efficiency retrofit works across Flintshire. A single supplier will install planned gas central-heating systems, renewable technologies, insulation and photovoltaic systems in Council-owned homes and private owner-occupied properties. The service also includes providing home-energy information through energy performance certificates or home-energy assessments. The appointed contractor will service and maintain air-source heat pumps and photovoltaic systems, including panels, metering and electronic data transfer. This is a combined building-services and energy-services requirement, covering boiler installation, insulation, heat-pump, solar, heating, ventilation and air-conditioning installation, and related energy services. Delivery is within the Council’s area and the opportunity is categorised as works.

The procurement has reached tender: Flintshire County Council invited offers through an open procedure. It has one lot and seeks one supplier. The tender submission deadline was 8 September 2026 at 12:00, and enquiries were accepted until 1 September 2026 at 12:00. The contract period is 1 December 2026 to 30 November 2028, with a renewal option of three years and a maximum end date of 30 November 2031. The estimated value is £25 million excluding VAT and £30 million including VAT. The Council planned to complete evaluation and award by 25 September 2026. Additional energy-efficient systems may be added as required. Bids may be submitted electronically in Welsh or English. Evaluation is 40% price, 40% quality and 20% social value.

This opportunity suits an established retrofit or building-services contractor able to manage a broad, single-supplier programme across domestic properties. Relevant capability includes installing gas central heating, insulation, air-source heat pumps and photovoltaic systems, together with the associated electrical, metering and data-transfer infrastructure. Suppliers must also be able to provide energy performance certificates or home-energy assessments and deliver ongoing servicing and maintenance for heat-pump and photovoltaic installations. The requirement favours organisations with strong programme-management capacity, competent installation teams and experience coordinating work in both Council-owned and privately owned homes. It is marked as suitable for small and medium-sized enterprises, while the breadth of services means a lead contractor may need demonstrable multi-disciplinary capability and reliable delivery partners.
