Question to the HM Treasury:

To ask the Chancellor of the Exchequer, whether she has made an assessment of the potential merits of introducing (a) fiscal measures and (b) tax incentives to promote the uptake of (i) heat battery and (ii) other low carbon technologies in homes.

The Government is committed to improving the quality and sustainability of our housing stock, through improvements such as low carbon heating, insulation, solar panels, and batteries.

Installations of qualifying energy-saving materials (ESMs) in residential accommodation and buildings used solely for a charitable purpose benefit from a temporary VAT zero rate until March 2027, after which they will revert to the reduced rate of VAT at five per cent. This support – worth over £1 billion – will aid households and charities in improving the energy efficiency of their buildings and help to reduce carbon emissions.
