Glad you have come to an amicable arrangement Reg

, I find them very fair in any dealings I've had with them.
We are with E-ON with a smart meter with £46 per month direct debit so £552 p.a. and I'm happy with that, we've been with them since 2012 and they come up with the best deal every time for our pattern of usage.
Of course living down here on the English Riviera we usually only get about 5 frosty mornings and the weather certainly is mild.
We pay nearly the same for water down here we have the most expensive water in the country, must be due to the fact it's always piddling down and they haven't found a way to catch it

it came in at £535 for 2019.
Oil is our heating source which is around £800 p.a. for a 3 bedroom house it seems pretty thermally efficient for a 41 year old house we have cavity wall insulation and the normal loft insulation and that's it.
If I consider the running costs are getting high I'll look into panels but quite frankly there are many a nice house wrecked aesthetically with these things hanging on the roof around our area so no thanks for the time being. I'd look into air heat source pump options before panels.
