Question to the HM Treasury:

To ask the Chancellor of the Exchequer, if she will make an assessment of the potential merits of zero rating for VAT buildings retrofitted to (a) Passivhaus and (b) AECB standards.

This 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. This will be vital to making the UK more energy resilient and meeting our 2050 Net Zero commitment.

Installations of qualifying energy-saving materials 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.

VAT is a broad-based tax on consumption and the 20 per cent standard rate applies to most goods and services. VAT is the UK’s second largest tax forecast to raise £171 billion in 2024/25. Taxation is a vital source of revenue that helps to fund vital public services.

One of the key considerations when assessing a new VAT relief is whether the cost saving is likely to be passed on to consumers. Evidence suggests that businesses only partially pass on any savings from lower VAT rates. In some cases, reliefs do not represent good value for money, as savings will not always be passed on to consumers.

The Government has no current plans to formally review the VAT treatment of building works. However, all taxes are kept under review as part of the tax policymaking process. The Chancellor makes decisions on tax policy at fiscal events in the context of the overall public finances.
