Worcester MT10 for Gas central heating
Does a setting of 25 on the heating dial create more cost than a setting of 18?

An important thing to consider: Setting your thermostat temperature higher will give you hot radiators, but it could decrease its efficiency. Ramping up the temp to max could decrease it by up to 20%, and send your heating bills skyrocketing.
If you want a lovely warm home and a long-lasting boiler, it’s about getting the right balance, around 18-21 is just right.
