We were told by an engineer to have a constant temperature all day as it works out cheaper as the boiler works less hard to maintain the temperature than try and heat a cold building from scratch each day
This can be true if that temperature set is low enough, but stick it on 23 and your bill will rocket. I think this advice is often greatly misunderstood which is why it often has a bad rep.
Set it to the right temperature for the times of the day and you will be better off. You need to analyse your own schedules, when you need heat and when you dont as well as how good your insulation is. We use 18 for daytime, 22.5 for morning heatup and evening cosy and then 16 overnight. Wife likes to ramp it up sometimes but our bills are still very low. £40 for a month in winter.
