No hot water in Codicote? 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 Codicote. For plumbing jobs in Codicote we work cleanly, isolate properly, and never just clamp a leak when it needs a proper soldered or pressed joint.

Quick answers on plumbing in Codicote
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.
Do you fit electric showers?▾
Yes, plus mixer, thermostatic and digital. We'll check your mains pressure first to recommend the right type.
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.
