The Treasury is widely reported to be considering cutting energy bills, perhaps via a VAT cut. What's the best way to do this?
We think the answer is to remove the taxes from electricity bills. Here is Nesta's proposal out for Tax-free Electricity:

I’ve successfully claimed £2,000 from Halifax for my heat pump install 🥳
To be eligible for the Green Living Reward the install has to be within 1 year of getting a mortgage/refixing.
You also need to have a current account with Halifax.

🏢 How are flats heated in England and Wales? 🏦
🔥 45% of 11+ storey flats use communal heating, at least half relying on fossil fuels
🏡 75% of low-rise flats (1-3 storeys) use fossil-fuel heating
⚡ 60% of high-rise flats use electricity for individual heating

I suggest OpenTherm as the mandated open protocol. Am I wrong?
