RETROFIT CREDITS, developed by HACT and Arctica Partners, is a carbon credits scheme that unlocks additional funding into social housing retrofit by verifying the emission reductions and social value of retrofit projects  combining the Net Zero Goal with an intrinsic part of the sectors DNA. 

  • It is UK-based, only the second verified scheme to be so.  
  • It is the only project in the world originating carbon credits for the decarbonisation of housing stock. 
  • It incorporates social value, measuring the positive impact retrofit has on residents’ lives.  

Social housing organisations - unlock retrofit funding

RETROFITCREDITS is an eligible source of co-funding to meet the balance of the eligible expenditure not supported by the Social Housing Decarbonisation Fund grant. The SHDF, based on BEIS’ latest guidance and its draft Grant Funding Agreement for successful Wave 2.1 bidders, requires at least 50% of costs to be co-funded by the housing provider or provided by third-party sources.


Looking to offset your carbon emissions?

With sustainability high on everyone’s agenda, how is your organisation tackling net zero goals?

Created to solve a need for additional funding for the social housing sector to meet the net zero carbon goal, RETROFIT CREDITS is an easy and innovative way of offsetting your carbon emissions and contributing to positive social change at the same time.

Is it really that simple?

We know, it sounds too good to be true,
so let’s break it down step-by-step!


The social housing provider enrols housing stock where retrofit works could improve the thermal efficiency of the home and/or reduce the carbon intensity of the heating source.


- Arctica calculates the potential emission reductions using the Verified Carbon Standard and projected funding available from RETROFIT CREDITS.
- HACT calculates the social value generated by the retrofit works using the UK Social Value Bank.
- The social housing provider uses the projected funding to inform their investment case for retrofit activities.


Once retrofit works are complete, Arctica originates Verified CarbonUnits (RETROFIT CREDITS) with Verra Registry backed by the certified emission reductions. This ensures the uniqueness and integrity of the credits issued.

- Arctica and HACT manage the sale of the RETROFIT CREDITS.
- The social housing provider receives payment for the emission reductions and social value created or uses the RETROFITCREDITS to compensate their unabated emissions.


Each tonne of CO2e reduced is eligible for up to 20 years of crediting (RETROFIT CREDITS are issued annually for up to 20 years) reflecting the real and permanent nature of the emission reductions

Calculating the social value

To calculate the social value attached to RETROFIT CREDITS, we used our UK Social Value Bank  which was developed with the sector for the sector. The social value can be aggregated to measure the impact of energy efficiency programmes at neighbourhood, place and national levels.

RETROFIT CREDITS Verified Carbon Units + Social Value

A certified product

HACT, along with our project partner, Arctica Partners, has developed a methodology to measure the carbon savings and social value created through retrofit activity. There’s no need to worry about greenwashing – To ensure the environmental integrity of the issued credits, this project has been developed under the Verified Carbon Standard, the world’s leading certification program for emission reduction projects. ​
