fourwalls are pleased to be working in partnership with the Sustainable and Traditional Buildings Alliance (STBA) in Bristol. The STBA were awarded the contract by Bristol City Council (BCC) to develop the 'design and technical guidance' to support a city-wide retrofitting initiative. The BCC 'Warm Up Bristol' scheme, commences in earnest this year - the same year that Bristol holds the European Green Capital status. It will be the biggest energy-efficiency scheme in the country, with a total estimated value of £60M. The qualifying retrofit houses will be solid wall, privately-owned properties, which can be difficult to treat. The funding…

We are pleased to launch our new website. The site has been updated to reflect the broad array of services that we offer. We continue to offer compliance testing and inspection services, such as Energy Performance Certificates, ventilation commissioning and thermography. But getting buildings to perform as intended requires a more holistic approach, which includes how occupants engage with their buildings, whether it is at home or at work. We hope that this new site will give you  good overview for what we can do, but please do get in touch - we would like to hear from you.
