Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what assessment she had made of the potential implications for her policies that heat batteries do not qualify for VAT relief through the Energy Saving Materials framework, while being MCS-certified and eligible for support under the Boiler Upgrade Scheme in the same way as heat pumps.

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. The list of qualifying ESMs, which includes but is not limited to heat pumps, can be found here: https://www.gov.uk/guidance/vat-on-energy-saving-materials-and-heating-equipment-notice-7086.

The Government assesses whether to add ESMs to this relief by evaluating them against the following tests: the primary purpose of the technology must be to improve energy efficiency and reduce carbon emissions; relieving the technology of VAT must be a cost effective lever for encouraging installations; and it must be practical for business to operate and for HMRC to administer.
