Retrofit Advice

There are approximately 27 million homes in the UK, and they are increasing at the rate of around 120,000 per year. New buildings are constructed to increasingly challenging carbon emission targets to meet Building Regulations. By comparison, the majority of existing buildings are less efficient, use more energy (per sq.m) and therefore more expensive to run. Retrofitting existing buildings to improve their thermal performance is becoming ever more important as we start to respond to, and adapt our building stock for climate change.

Retrofitting needn’t be complex, but there will be challenges. Making the right choices is the most important stage of a retrofit, and there’s a huge range of choices: design strategies for insulation, ventilation, airtightness, renewables, etc.; material selection; calculations for thermal improvement, moisture and cost; work sequencing; and so on.

fourwalls can help you with your project. Whether you are planning a partial retrofit to your home, perhaps as part of an extension; a full retrofit, either ‘shallow’ or ‘deep’, we can assist you and make sure you make the right decisions. And it’s not just homes. We have substantial experience in the non-domestic sector: village hall through to industrial premises.

We have expert knowledge in this field. In addition to advising individual building owners, social housing landlords, and commercial clients, we are regularly involved with government and other public funded programmes to offer strategic advice. These include:

  • Technical input for Approved Document L1B for the Department for Communities and Local Government (DCLG)
  • Technical evaluation and Post Construction Review surveyor for Innovate UK’s Retrofit for the Future £17M programme
  • Technical reviewer for the Responsible Retrofit Guidance Wheel for the Sustainable Traditional Buildings Alliance (STBA)
