No heating or no hot water
We check controls, demand signal, ignition sequence, gas supply status, diverter valve operation for combis, and whether the system can circulate properly.

Local boiler fault-finding
Fast boiler repair help when your heating goes off
When a boiler fails it is rarely convenient. It can mean no heating, no hot water, low pressure, or worrying noises that make you switch the system off.
For boiler repairs in Telford, we focus on two things: finding the actual cause quickly and fixing it properly, rather than resetting the boiler and hoping it holds. Our engineers work through a structured fault-finding process, then explain what has failed, what it takes to repair, and what it is likely to cost.
At telford plumbers we are plumber specialists serving Telford, so our work is grounded in the kinds of systems common across the area. Many properties have combi boilers with sealed systems and radiators that need correct pressure and circulation to run reliably, and a lot of callouts come down to a small number of repeat faults that still need careful diagnosis.
If you have turned the boiler off for safety, tell us what you noticed first—leak, bang, smell, error code, or loss of pressure. That short history often cuts the diagnostic time and gets heat back on sooner.
Boiler faults diagnosed properly
Common boiler problems we repair
Pressure dropping or frequent topping up
Often caused by a leak on the heating circuit, a faulty pressure relief valve, or an expansion vessel issue. We locate the cause and correct it rather than treating the symptom.
Boiler leaking
Leaks can come from pipework, pump seals, internal components, or the condensate route. We isolate safely, identify the source, and repair or replace the failed part.
Kettling, banging, or gurgling noises
Noise is commonly linked to poor flow, air in the system, pump problems, or heat exchanger issues. We test circulation and recommend the right fix for the fault found.
Radiators cold in places
We investigate balancing, trapped air, sludge-related restriction, and valve problems. If a system clean is needed, we explain why and what it involves before proceeding.
Fault codes and lockouts
We interpret the code as a starting point, then confirm the fault with proper checks on sensors, ignition, fan operation, and safety devices.
Methodical diagnosis
How we approach boiler repairs in Telford
A good repair starts with good diagnostics. We begin with basic safety checks, confirm the reported symptoms, and then test in a logical order so we do not replace parts on guesswork.
Typical steps include checking system pressure, verifying the boiler is getting a correct heat demand from the controls, confirming the condensate route is clear, and testing key components like the pump, diverter valve on combi boilers, and sensors. If we suspect a circulation issue, we look at radiator temperatures and return flow to see whether heat is moving around the system.
Telford homes often have a mix of older and newer heating layouts, so access and pipework routes can vary. In some properties the boiler and controls are boxed-in or sited in a cupboard, which makes careful isolation and tidy working even more important.
If the repair needs parts, we will be upfront about lead times and options. When a repair is not the best route, we will say so clearly, explain why, and talk through the next sensible step rather than pushing an on-the-spot decision. If you are also planning a replacement, our boiler installation service covers selection, fitting, and commissioning.
From diagnosis to handover
What to expect on a repair visit
-
01
Quick triage and safety checks
We confirm the symptoms, check for active leaks or obvious risks, and make the area safe to work in before opening the boiler.
-
02
Fault-finding and explanation
We test likely causes first, then narrow it down. You get a plain explanation of what has failed and what repair options make sense.
-
03
Clear price before repair work
Once we know the fault and the parts or labour needed, we give you the cost to proceed. If you choose not to go ahead, you still have a clear diagnosis to work from.
-
04
Repair, test, and tidy up
After the fix we run the boiler through heating and hot water where applicable, confirm stable pressure, and leave the work area clean.
How Much Does Boiler Repair Cost in Telford?
Boiler repairs in Telford typically cost about £120 to £450 for common faults, with more complex issues and major components sometimes running £500 to £900+. A straightforward fix like replacing a sensor or freeing a stuck component can be at the lower end, while jobs involving a pump, fan, or significant internal parts usually cost more.
Your final price depends on the fault found, parts availability, boiler make and model, access—for example a tight cupboard install—and whether there is additional work needed on the heating circuit such as leak tracing. Exact costs are confirmed after diagnosis during the repair visit.
Customer experiences
Boiler faults found, explained and repaired
“Boiler pressure kept dropping and we were topping it up every couple of days. They found the cause quickly, explained it in plain English, and the repair was neat. Pressure has stayed steady since.”
“No hot water on a cold morning and the boiler was locked out. The engineer checked everything properly rather than guessing, replaced the failed part, and talked me through what happened.”
Straight answers
Boiler repairs Telford: questions we get asked
Can you repair a boiler the same day in Telford?
Often, yes, if the issue is diagnosable on site and the required part is available quickly. Same-day repair depends on the time you contact us, how urgent the fault is—for example a leak—and whether the boiler needs a specialist component.
My boiler is leaking. Should I turn it off?
Yes, if you can do so safely, turn the boiler off and stop the heating to limit damage, then get it checked. A leak can be as simple as a fitting or seal, but it can also indicate a failing internal component that should not be left running.
Why does my boiler pressure keep dropping after I top it up?
Repeated pressure loss usually means water is leaving the sealed heating circuit through a leak, a faulty pressure relief valve discharge, or an expansion vessel problem. Topping up is a temporary workaround; the underlying cause needs diagnosing to prevent corrosion and further breakdowns.
Do you repair combi, system, and regular boilers?
Yes. The diagnostic approach changes slightly with the type of system, because combis use a diverter valve to switch between heating and hot water, while system and regular boilers rely on stored hot water and different controls. We identify what you have and test accordingly.
What should I check before booking a boiler repair?
Check that your programmer or thermostat is calling for heat, your boiler has power, and the system pressure is within the normal operating range shown on the gauge. If the boiler shows a fault code, note it down. If you smell gas, do not try to diagnose it yourself; follow the safety instructions for your property and get urgent help.
When is repair not worth it and replacement makes more sense?
Replacement can be the sensible option when a boiler has repeated breakdowns, key components are no longer economical, or parts are hard to source. If we believe you are likely to spend good money chasing multiple faults, we will say so clearly and explain the options, including whether a like-for-like swap is feasible.
