Common Boiler Problems We Repair

We regularly repair faults including:
-
No heating or hot water.
-
Boiler not igniting.
-
Low boiler pressure.
-
Boiler losing pressure regularly.
-
Water leaks from the boiler.
-
Frozen condensate pipe.
-
Fault codes displayed on the boiler.
-
Strange banging, whistling or vibrating noises.
-
Radiators not heating properly.
-
Boiler repeatedly locking out.
-
Faulty pumps, fans or diverter valves.
-
Expansion vessel failures.
-
Pressure relief valve faults.
-
Ignition and flame detection faults.
-
Thermostat and heating control problems.
Our engineers carry out a thorough diagnosis before recommending the most appropriate repair, ensuring that unnecessary parts are not replaced.
Should You Repair or Replace Your Boiler?
One of the most common questions we receive is whether it is worth repairing an older boiler.
The answer depends on several factors, including the age of the appliance, the cost of replacement parts, the overall condition of the heating system and the frequency of previous breakdowns.
In many cases, repairing the boiler is the most cost-effective solution. However, if your boiler is over 12 to 15 years old, requires frequent repairs or has become inefficient, replacing it with a modern energy-efficient boiler may provide better long-term value.
At Jac Plumbing & Heating Services Ltd, we always provide honest recommendations based on your individual circumstances. We never pressure customers into replacing a boiler if a safe and reliable repair is the better option.
Safety Is Always Our Priority
Gas appliances should only ever be repaired by a qualified Gas Safe Registered engineer. Attempting DIY repairs or using unqualified individuals can place your family and property at serious risk.
If we discover that a boiler is operating unsafely, we will clearly explain the issue and take the appropriate action in accordance with Gas Safe procedures. Where necessary, we may classify an appliance as At Risk (AR) or Immediately Dangerous (ID) and advise you on the safest course of action.
Our commitment is to protect your safety while providing practical, cost-effective solutions.
