What Energystore does
Energystore Ltd is a privately held, family-owned manufacturer and installer of expanded polystyrene (EPS) bead-based insulation systems, headquartered in Holywood, Northern Ireland and founded in 1974. The company designs, produces and installs insulation for walls, floors and roofs across the UK and Republic of Ireland, operating six production sites and an approved installer network of approximately 200 KIWA-assessed contractors. Its product portfolio comprises Superbead (injected cavity wall and beam-and-block insulation, protected by EP4079990), TLA (Thermal Lightweight Aggregate, a pourable cement-bonded EPS insulation for floors and roofs with A2-s1,d0 fire rating), Spacebead (an aerogel-EPS injected cavity wall system and patent-pending technology with 0.029 W/mK thermal conductivity) and the Energystore+ low-carbon range manufactured with BASF Neopor BMB and certified by REDcert2. The company has been the largest EPS bead insulation manufacturer in the UK and Ireland since acquiring WarmFill in 2021, and its products are used in approximately one in eight new UK buildings, with over 400,000 homes insulated cumulatively.
The business operates a hybrid go-to-market combining enterprise field sales to developers, housing associations and contractors across GB, NI and ROI; an approved installer channel with 10-year insurance-backed warranties; an in-house contracting division for direct homeowner installations; and grant-funded distribution under the Northern Ireland Sustainable Energy Programme (NISEP) including the Thermal Comfort and HELP TO INSULATE schemes. Revenue is generated through product supply (one-time sales), professional installation services, and licensed offerings such as the Facadeclick circular facade system. The company has executed an acquisition-led growth strategy, integrating WarmFill (2021), Northern Loft Insulation (2024) and Advanced Traditional Screeding (2024), while investing in emission reduction under its Emission-less Mission targeting net-zero operations by 2028. The group has approximately 90 employees and is led by Managing Director Connor McCandless.

Energystore competitors and assessment
Company assessmentDirect peers
- Kingspan Group: Irish-headquartered global leader in insulation and building envelope solutions, including rigid foam insulation boards competing directly with Energystore's Superbead, TLA and Spacebead in the UK & Ireland new-build and retrofit markets.
- Xtratherm: UK & Ireland manufacturer of PIR rigid foam insulation for roofs, walls and floors; directly competes with Energystore's TLA pourable floor/roof insulation and Superbead cavity wall products in commercial and residential construction.
- Recticel: Belgian manufacturer of PIR and EPS insulation products for building applications, including cavity wall, floor and roof systems that overlap materially with Energystore's product portfolio across European and UK markets.
- Unilin Insulation: UK & Ireland PIR and EPS insulation manufacturer with a comparable product range covering floors, walls and roofs; competes with Energystore on new-build specifications and retrofit projects through builders' merchants.
- Celotex: UK PIR insulation manufacturer (part of Saint-Gobain) supplying insulation boards for floors, walls and roofs; competes head-to-head with Energystore TLA and Superbead in new-build residential and commercial construction.
Broad incumbents
- Saint-Gobain Isover: Global insulation giant offering glass mineral wool and other insulation systems; broad incumbent that competes across multiple categories with Energystore's wall, floor and roof insulation in UK and Ireland.
- Knauf Insulation: Major global manufacturer of mineral wool and other insulation products; broader incumbent serving the same UK & Ireland construction channels as Energystore with overlapping applications in walls, floors and roofs.
- ROCKWOOL: Global stone wool insulation manufacturer with extensive UK presence; competes with Energystore across cavity wall, floor and roof applications, with a different material technology (stone wool versus EPS).
- IKO: European manufacturer of roofing and insulation systems including PIR boards; broader incumbent that overlaps with Energystore's TLA pourable roof insulation and other roof applications in the UK and Ireland.
Regional players
- PermaRock: UK-based external wall insulation (EWI) and render systems provider; adjacent competitor in the building envelope space, particularly relevant as a partial substitute for Energystore's cavity wall insulation under future regulatory pathways.
