Whole-House Retrofit & Insulation

Whole-House Retrofit & Insulation Solutions Delivered the Right Way

Whole-House Retrofit & Insulation (EWI / IWI)

We deliver whole-house retrofit and insulation solutions that improve building performance, comfort, and long-term energy efficiency. Our approach goes beyond individual measures, focusing on how insulation, ventilation, and heating systems work together as a complete building system.

As a trusted delivery partner for social housing providers, councils, landlords, and homeowners, we design and install external wall insulation (EWI) and internal wall insulation (IWI) as part of compliant, performance-led retrofit programmes across the UK.

System-Led, Fabric-First Retrofit Delivery

Effective retrofit starts with the building fabric. Our whole-house approach ensures insulation measures are correctly specified, coordinated, and installed to deliver lasting results without creating unintended consequences.

Our process includes end-to-end system design and retrofit coordination to PAS2030 standards.

  • Social housing providers and local authorities

  • Landlords and portfolio owners

  • Homeowners planning energy efficiency upgrades

  • Retrofit and decarbonisation programmes

  • Properties preparing for renewable heating systems

Our comprehensive design and planning approach reduces risk, improves outcomes, and provides confidence for clients managing both individual properties and large housing portfolios.

Key Benefits

Despite these diverse developments, developments in fossil fuel systems almost entirely eliminated any wind turbine systems larger than supermicro size. In the early 1970s, however, anti-nuclear protests in Denmark spurred artisan mechanics to develop microturbines of 22 kW.

Whole-House System Design

Insulation is designed alongside ventilation and heating requirements, ensuring thermal performance improvements are maximised safely.

Quality-Assured Installation

Our experienced teams deliver insulation works to consistent standards, supported by inspection, verification, and performance assurance.

25 Year Insurance Backed Guarantee

All our works are manufacturer and labour guaranteed for 25 years including brick and render finishes.

Key Benefits

Yes. Treating the home as a complete system avoids performance gaps and reduces the risk of issues such as cold spots, condensation, or uneven heating. Whole-house retrofit delivers more consistent comfort and long-term energy savings.
Insulation alone does not cause problems — poor ventilation planning does. We always assess ventilation requirements alongside insulation to maintain healthy indoor air quality and moisture balance.
Not always. Planning constraints, building type, or location may limit suitability. Where EWI is not appropriate, internal wall insulation can provide an effective alternative. Each property is assessed individually.
Yes. Insulation performs best when delivered as part of a coordinated retrofit programme that considers heating, ventilation, and future decarbonisation measures.
