No hot water in Tewin? Plumbing sorted properly
No hot water but heating still works? On a combi, that's almost always a diverter valve, diaphragm or PCB issue. We carry the common parts, diagnose on-site and usually get it fixed in one visit across Tewin. For plumbing jobs in Tewin we work cleanly, isolate properly, and never just clamp a leak when it needs a proper soldered or pressed joint.
You're not getting a call centre — you're getting Grant.
The same engineer quotes the job, does the work, and answers the phone afterwards if anything's not right.

plumbing in Tewin: questions we get a lot
Why have I lost hot water but heating still works?▾
On a combi boiler this is the classic diverter valve symptom — the valve that switches the flame between heating and hot water has stuck. Common, and usually a one-visit fix.
How much will it cost?▾
Diverter valve replacement on most boilers is £180–£320 fitted. We'll give you a fixed price after diagnosis before any work starts.
How fast can you respond to a burst pipe?▾
We aim for same-day. Call us first — we can talk you through stopping the water immediately while we head over.
Can you find a hidden leak?▾
Usually yes — we use thermal imaging and pressure testing to trace leaks behind walls and under floors before we cut anything open.
