Good to know in Willenhall
- Water: most homes in the WV13 postcode district are supplied by Severn Trent Water. Hardness in the main supply zone is 151 mg/l (moderately hard). Harder water leaves limescale in boilers, immersion heaters, showers and taps, so it is worth asking about a scale reducer or filter when a new boiler or water heater goes in.
- Drains and sewers: Severn Trent looks after the public sewers here, including most shared drains that serve more than one property. A blocked drain inside your own boundary is usually yours to clear.
- Gas: Cadent runs the gas network across the West Midlands. If you smell gas, call the free national gas emergency line on 0800 111 999 straight away, before you call a gas engineer.
- Planning and building regulations: Walsall Council handles planning applications and building control for Willenhall. Larger jobs such as extensions, new windows and rewiring need building regulations sign off, which your tradesperson can often self certify through a scheme such as Gas Safe, NICEIC, NAPIT or FENSA.

What a heating engineer does
Heating engineers keep the whole system running: annual boiler servicing, radiators that stay cold, thermostats and smart controls, flushing sludge out of pipework, and replacing pumps and valves. Gas work in Willenhall 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 Willenhall?
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.
