Top tips
Hiring a plumber, without the regret.
Four moves that separate a smooth job from a nightmare.
Always ask for the Gas Safe ID.
If gas work is part of the job, the engineer must show their Gas Safe registration card. Verify the number at gassaferegister.co.uk before they touch anything.
Get three written quotes.
Plumbing prices vary wildly by job and area. Three quotes shows you the market — anything more than 20% out from the others is a flag.
Insist on parts receipts.
For boiler parts, valves and cylinders, ask for manufacturer receipts. Genuine parts come with warranty; refurbished kit often doesn't.
Hold final payment until tested.
Pay in stages, not upfront. Hold the last 10–20% until you've run hot taps, flushed the system and seen the certificate.

Plumber explained
A heated towel rail does two jobs — warms the bathroom and dries your towels. Sizing matters: cheap rails are undersized and end up boosting the system to compensate, costing more in gas.
What's involved
- Drain section of heating circuit (or wire electric element)
- Fit rail to wall on supplied brackets
- Plumb to flow + return (BS EN 442) or fit electric element + spur
- Refill, bleed and test pressure
Typical UK costs (2026)
| Item | Cost |
|---|---|
| Standard chrome rail supply + fit | £180–£350 |
| Anthracite / designer rail supply + fit | £280–£600 |
| Electric-only rail (Part P required) | £280–£500 |
| Labour only (you supply rail) | £120–£220 |
Sizing
Use a BTU calculator — typical UK bathroom needs 1,500–3,500 BTU. Premium chrome rails lose 10–15% output vs anthracite.
