Gas work in Old Windsor still needs a Gas Safe registered engineer; the rest, such as balancing radiators or fitting a thermostat, does not.

Frequently asked questions
Why are my radiators cold at the top?
Usually trapped air. With the heating off and the radiators cool, open the bleed valve with a radiator key until water appears, then close it and check the boiler pressure. Radiators cold at the bottom or in the middle often point to sludge, which a heating engineer can flush out.
Why is one radiator cold at the bottom or the top?
Cold at the top usually means air, which bleeding fixes. Cold at the bottom or the middle usually means sludge, which a power flush or a chemical clean deals with. A radiator that is cold all over while the others are hot is often a stuck valve.
What is a power flush and do I need one?
A power flush pumps cleaning chemicals and water through the system at speed to clear sludge. It is worth it when several radiators are cold at the bottom or the boiler is noisy, and most manufacturers require the system to be clean before a new boiler goes in.
Is it worth fitting a smart thermostat?
It can be, if your heating runs on a simple timer and you are out at different times. The saving comes from heating the house less when nobody is in, not from the device itself, so be realistic about how you would use it.
How do I get a quote from heating engineers in Old Windsor?
Pick a listing on this page and send a quote request saying what needs doing and when suits you. The business comes back to you with a price and a time. It is free to ask, and no payment is taken online.
Are the heating engineers on this page vetted?
Not yet. Listings marked Claimed have been claimed by the business and are kept up to date by them; the rest come from public records such as Companies House and Google and are marked as not yet claimed. Every listing shows its real Google rating and review count where one exists. We do not check registers or insurance yet, so ask for a Gas Safe or NICEIC/NAPIT number and check it yourself.
What should I check before I hire a heating engineer?
Ask for a written quote and what it includes, who will do the work, whether they are insured, and any registration the trade needs, such as Gas Safe for gas work or a Part P scheme for electrics. Never pay the full amount up front.
Prices and availability are confirmed by each business. No payment is taken online, you pay the tradesperson directly.
