A gas service and an oil service are different jobs with different checks and different paperwork, so each has its own page.

Tell the dial when it was last done and it tells you how long you have.

Regular maintenance keeps a heating system working efficiently and cost-effectively. Our engineer carries out a full service of the boiler and the heating system to make sure it is safe and running at its best, and will tell you which parts are wearing so they can be replaced before they fail and damage something more expensive.

I have used Sterling Heat on few occasions: removing old system and installing new combi boiler, connecting radiators, pipework adjustments, gas hob installation. Always professional and very helpful! Very knowledgeable! Best in the area!
We’ve used Gary several times since buying our house 7yrs ago for small jobs. Now we need a new boiler we feel lucky to have someone we know and trust to do a good job at a fair price.
Gary is great at his job and takes time to make sure it is done to the highest standard. I completely renovated my house so needed heating and wet plumbing.
Once a year, for gas, LPG and oil. Manufacturers require an annual service to keep the warranty valid, and a yearly check is what catches the worn part before it becomes a winter breakdown.
Late summer or early autumn, before the heating goes back on. Engineers are busiest from October to January, so a September service means you are not waiting in the cold if something needs a part.
About an hour for a gas boiler and around an hour to an hour and a half for an oil boiler, which has more to clean. You will need to be in to let us in and to show us the boiler, controls and, for oil, the tank.
Yes. All makes and models, gas, LPG and oil, whoever fitted them.
A written service record. For oil boilers that is the OFTEC CD/11 form. For gas boilers we complete the service record in the manufacturer log book, which is what the warranty needs, and we can provide a landlord gas safety record (CP12) at the same visit if you let the property.
