Heating Working but Gas Bills Too High
Nothing is broken, but the running cost has climbed noticeably..

What is actually going on
Nothing is broken, but the running cost has climbed noticeably.
The realistic causes, in order
A boiler running at a flow temperature that prevents condensing operation Poor controls — no room thermostat, no thermostatic radiator valves, or a schedule that heats an empty house System fouling reducing heat transfer, so the boiler runs longer for the same comfort
What we test on site
Flow and return temperatures under real conditions Control strategy and schedule against how the house is actually used System water quality and radiator performance
Questions we get asked
What causes heating that costs more than it should on a gas boiler?
A boiler running at a flow temperature that prevents condensing operation
What normally puts heating that costs more than it should right?
Controls, flow temperature and system cleanliness are the three levers that reliably reduce run time.
Is it safe to keep using the system with heating that costs more than it should?
Efficiency claims should be based on what's measurable in your system. We won't promise a percentage saving we can't demonstrate.
