How much should the UK Government invest to make upgrading the nation’s homes affordable and attractive? Working with industry experts and academics, the UK Green Building Council has a created this calculator to open the books so you can ‘play’ Chancellor and Secretary of State.

Use the calculator to work out, as Chancellor, how much you would invest over what time frame. Who would you prioritise – people living social housing or privately owned homes? Fuel-poor residents or asset-rich owner occupiers? Which retrofit measures would you prioritise? How will your choices impact on energy bills, returns to the Treasury, public health, and climate emissions? As Secretary of State, what policies and regulations would you introduce to encourage private investment and shift markets?

The calculator has been developed to allow an evidence-based debate on the magnitude of investment and policies needed and to help us all assess policy decisions and priorities.
