How much are you spending day? I live in a normal 1960s semi all modernised with modern gas central heating, new upvc windows and good insulation. Heating is off all night. It’s on 19 degrees from 7am to 8pm so only ticking over on and off after initial morning warm up. Daily use on smart meter is around £15 in this cold weather is that normal? Or can i check meter is charging the right amount? Our house is never as warm as we had it before as we used to have it on 20.5. I turn heating off/ down if we’re all out. It just seems really expensive!
