The Supply Chain Sustainability School has recognised the need for collaboration and upskilling around retrofit. We have brought together a group of partners to work on this with the School in the Retrofit Leadership Group.
This group works together to look at how we can upskill industry in retrofit.
At the end of 2023, we launched new learning, assessments and a programme of events on the retrofit topic. Please scroll down to see the latest learning.
The group’s outcomes – The retrofit learning, assessments, and events – have been developed and delivered with sponsorship support from NatWest Group – Learn more about this here.
Retrofit requires significant investment and change, fast.
Organisations from across the built environment sector are adapting to include retrofit in their work. The demand for retrofit is increasing rapidly and it encompasses elements from different areas in our sector.
The UK has some of the oldest building stock in the world. 80% of all the buildings in use by 2050 have already been built.
29 million homes need to be retrofitted to enable the UK to hit its 2050 carbon emissions targets. For this to happen, the retrofitting industry needs to grow by ten times its current size. Retrofit isn’t only required in domestic settings; commercial, public and historical buildings need improving.
70% of the UK’s non-residential buildings were built before 2000.
Buildings a lot older are still in use, with 2% of the UK’s buildings being counted as “listed buildings” due to their heritage status.

The UK’s buildings need to be more efficient. They need to use less energy, lose less energy and enable the efficient dispersion and generation of energy.
Retrofitting existing buildings will allow individuals and businesses to save money and be more sustainable. It will let people across the UK live in warmer and healthier homes. Crucially, it will help our industry, and the country as a whole, decarbonise.
This is not just something construction industry should do, but it will have to do. Increasing legislation around building efficiency alongside market expectations means that buildings must change.
Retrofit assessment
Benchmark your own individual retrofit knowledge against the industry. If you want to assess your organisations capability in assessment, your School account admins will be able to do a company retrofit capability assessment on their dashboard.
