Mother is living with us (92), we're all retired so at home most of the

Are these temperatures asking for a humungous bill?
Never had CH before.

If you were heating the whole house before by other means you might well
find a reduction in bills. A central heating boiler is more efficient than
gas fires, etc.

I'd say your nighttime setback to 18c isn't enough. Many would find
unnecessarily high when in bed. 15 would be more normal - and a well
insulated house probably won't drop this low anyway even with the heating
off.
