Procast Group

What Procast Group does

Procast Group is a privately held, founder-owned full turnkey retrofit contractor headquartered in Hamilton, Scotland. Founded in 2007 by Derek Innes, the group operates eight business divisions — Procast Building Contractors, Procast Energy Services, Procast Property Services, Procast Innovation, Procast Consultancy (via the December 2024 JC+P acquisition), Brimar Electrical Solutions, Thermsaver Heating Solutions, CHES, and Curtis Heating — delivering external wall insulation, cavity and loft insulation, solar PV with battery storage, air source and ground source heat pumps, mechanical ventilation with heat recovery, EV charging, gas infrastructure (GIRS CCCR accredited), and end-to-end PAS2035/PAS2030 whole-house retrofit programmes to housing associations, local authorities, and other public sector bodies across the UK.

The company's underlying technology stack spans conventional fabric-first retrofit measures alongside pioneering elements such as indoor air-source heat pumps co-developed with Trianco, phase-change thermal storage (Sunamp Heat Batteries), and an in-house gas, electrical, heating, and design capability integrated through the multiple divisions. Approximately 130+ staff are deployed across bases in Hamilton (head office and registered office in Airdrie), Aberdeen (established 2024), Dumfries (April 2025), Forfar, and Glasgow; more than 15% of the workforce are apprentices or graduates.

Procast earns revenue almost entirely through competitively tendered contracts and framework agreements, with pricing ranging from approximately £15,000 (small private PV installs) to £12.55m (Home Group Cumbria PAS2035 programme). Distribution is anchored on national and regional public procurement frameworks — including the £980m Greater Manchester Net Zero Housing Retrofit Framework (Lot 13), the £120m SPA N9 Scotland-wide framework (17 of 23 lots), and the £800m CHIC Healthy Homes framework — supplemented by direct contractual wins and a new direct-to-residential ASHP installer channel via ScottishPower. Disclosed FY2025 turnover was £70m (25% over budget) with a stated FY2026 budget exceeding £80m.

Revenue model

1. Public sector retrofit and construction contracts: Procast Group generates the majority of its revenue through competitively tendered contracts with public sector bodies, housing associations, and local authorities. Revenue is project-based, earned through framework agreements and direct contracts for retrofit, refurbishment, new build, and energy installation works. The company targets £80m turnover for FY2026, having achieved £70m in FY2025 (25% over original budget). JC+P acquisition adds £640,000 in turnover to the group.
2. Housing association retrofit programmes: Large-scale PAS2035/PAS2030 whole-house retrofit programmes for housing associations (e.g., Home Group £12.55m in Cumbria), including fabric improvements, heating systems, PV, and ventilation. Revenue is earned as a fixed-price or NEC3 contract sum for delivery of specified retrofit works.
3. Government grant-assisted residential retrofits: Projects partially funded through government grant schemes including ECO4, Scottish Net Zero Heat Fund, Boiler Upgrade Scheme, and Energy Companies Obligation 4 (ECO4), where Procast facilitates and delivers works on behalf of eligible households. Government funding reduces customer cost barriers.
4. Thermal storage installation (EXTEND project): Procast provides installation workforce for the Sunamp EXTEND project (£1.2m+ partnership) installing thermal storage systems in approximately 60 UK homes, funded by UK Government DESNZ Net Zero Innovation Portfolio (£9.25m to Sunamp).
