Things like insulation, wind turbines, solar panels and wood burners providing hot water only attract 5% VAT to encourage their use to meet the EU's punishing yet completely futile and unnecessary global warming targets. By increasing the VAT to 15%, buying and producing environmentally damaging electricity is more tax efficient than producing what is billed as clean electricity.
The Climate Change Minister, Greg Barker, has put together a robust response to the interfering busybodies in Brussels - he's started a Twitter campaign to try and get them to change their minds. Truly pathetic and a demonstration of who really runs the country under this supposedly eurosceptic Prime Minister and his merry band of europhiles.
Having created a whole industry from nowhere with the global warming scam, the EU is now going to reap the profits from the unsustainable "green" industry it created before it all collapses by tripling VAT on what it produces.
