Gas Useage???

So it's not the boiler at all.


I assume you have bled the radiators.


Silted radiators are lukewarm.


Condensing boilers can be too clever. The old boilers churn out 70 degree ( or what you set it at ) hot water so a single plate did the job, but a condensing boiler can merrily keep things mellow at 50 degrees. Double plate instead of single plate is simple to do.

Worded my last post wrong. Every room other than the kitchen / dining room (this is where my thermostat is!) achieves over 20 degrees. I would say the radiators for kitchen / dining room are not sufficient.

What is the temperature setting for CH water on the boiler?


If that isn't the problem, it isn't normally difficult to fit double or triple panel replacement radiators - they are often standard length.
