Homes hoping to shrink their carbon footprints by installing a solar-battery system face a steep VAT increase from October under new laws proposed by HMRC.
Meanwhile, home coal supplies will continue to receive the lower VAT rate.
It also warned that the move would push back the take-up of solar-battery systems by years even as the UK works towards becoming a net zero carbon economy by 2050.
Nina Skorupska, the REA’s chief executive, said the increase would “create a barrier to British homes and businesses who are seeking to take action on climate change and reduce their bills by installing solar with battery storage”
She said the government “should be doing all it can to install these technologies rather than enacting barriers”.
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.
Juliet Davenport, Good Energy’s chief executive, said the rise was “possibly the worst way to respond to a climate emergency”.
“The government should be seeking to be a world leader in renewable technologies, but it’s damaging our successful solar industry and putting green jobs at risk. We urge the Treasury to listen to the thousands of petitioners who want to play their part in fighting climate change,” she said.
HMRC brought the secondary legislation to parliament on Monday after carrying out an industry consultation on the plans in April and May this year. It has said it is offering as much tax relief as possible for home renewable energy systems while ensuring the UK is in line with EU law.
The 5% VAT rate will still be allowed for housing associations and buyers who are over the age of 60 or receive certain benefits.
The lower rate will also apply to the labour costs associated with installing the system while the 20% rate will be applied to the hardware only.
