Hi group,

Today I completed the monthly on line meter readings submission for my
energy supplier and was presented with a bill for about £450 for the past

TRVs on radiators are very effective and how you program your roomstat.
Having it lower during the day when you are either out or relatively active and
much lower during the night. Then of course, only heating the water when it's
required. These changes would make a substantial difference, if not already
done.
