no mention of means testing on our letter.
Do you have oil heating?
I think there’s a scheme for people who aren’t on mains gas to get a heatpump, insulation & solar installed that isn’t means tested (AFAIK). I believe it’s only available as a package (e.g. you can’t get the solar & insulation without also taking the heatpump), and think that it is a contribution towards the cost, rather than ‘free’ as such.[**]
There are too many sharks in the water for me to investigate much further, and we have a nice, new oil boiler that is much cheaper to run than a heat-pump and can use bio fuel when it becomes widely available.
Edit [**] This is in Wales. Ingerlund has different schemes, apparently.
