The Green Party are arch remainers:
HMRC has blamed EU tax laws for the planned rise because they rule out lower VAT rates for energy saving equipment under state aid rules.
The European court of justice ruled in 2015 that energy saving materials should not have been receiving the reduced rate of tax. This led to an increase in VAT for solar systems installed at new-build homes in 2016, but did not affect the majority of houses which would require retrofitting. Those houses will now be affected by the higher rate.
The REA has called on HMRC to cancel the latest increase, which would come into effect as the UK prepares to leave the EU. Any rise should be cancelled as soon as possible after Brexit, the trade group added.
