Homes UK 2020 was a fantastic conference with many great events and speakers. The final day was full of gems, and the stand-out panel for me discussed the cost of net-zero retrofit and the solutions needed.
Following a survey of over 200 councils and housing associations, the expert panel discussed the current average energy efficiency ratings for social housing, the targets social landlords have set to achieve net-zero and how much they estimate retrofitting will overall cost.
The top-line points from this thought leadership are:
- 21% - the percentage of social landlords surveyed who were able to define what net-zero will look like in their housing stock
- £20,742 – the average per unit cost expectation for achieving net-zero
- £104bn – the total sector cost by of achieving net-zero by 2050, based on the roughly 5 million social homes in the UK
- £3.8bn – government Manifesto commitment (the first tranche of Social Housing Decarbonisation Fund was for £50m)
- D – the average EPC rating of current social housing stock
- 500,000 – the number of new tradespeople needed to deliver this initiative
Four our Social Housing clients, residents typically pay for energy as a service, with the housing provider partially subsidising cost rises. Therefore, both the organisation and the residents stand to benefit from reduced energy consumption. For providers committed to reducing the environmental impact of operations and becoming a sustainable housing provider, a reduction in usage could deliver lower carbon emissions, improved local air quality and health benefits for residents.
Using the roughly £20,000 unit cost, what’s the best way to go about this retrofit? There have been plenty of pilot projects, but the key lies in making sure any solution suits the building fabric: for better or for worse, there is no ‘one size fits all’ option. Consultants and providers need to carefully consider this infrastructure and knowledge in approach for each unique scheme.
