I don’t often visit this section of the forum, I usually just go to the PPMS group so if it has been mentioned I apologise now.
Are you aware that if you are getting ESA, DLA, PIP or Tax Credits you can get a discount on your fuel bills? I’ve just realised and applied, though to be fair I’m a bit slow! Just go onto your suppliers website and find a link for warm front discount and fill the form in. British Gas pay £135 and will also insulate for free.
Take care and put the heating back on.
