Boiler Repairs Across the Region
If your boiler has stopped heating, is losing pressure or leaking, contact us for a repair assessment. We identify the fault, explain the work and cost before starting, then restore safe heating.
Repair Support
A cold home, fault code or leaking boiler needs diagnosis, practical advice and an engineer who can safely complete repairs.
What Our Boiler Repair Service Covers
Our repair service suits gas or oil boilers, including older systems that need repair rather than immediate replacement. Gas Safe and OFTEC registration means the right engineer handles each fuel type.
We check connected controls, list needed parts and provide a written quotation before work starts. If repair no longer makes sense, we explain replacement options.
Fault diagnosis
No heating, a fault code, low pressure or a leak all need a proper diagnosis. We test the boiler and trace the fault before recommending work.
Gas and oil boilers
Gas Safe engineers work on gas boilers, while OFTEC-registered engineers handle oil-fired systems. That matters for homes heated by oil or LPG off the gas grid.
Older heating systems
An older boiler may still be repairable. We assess its condition, the available parts and the wider heating system before advising you to replace it.
Controls and connected faults
A boiler fault can involve the controls or another part of the heating system. We check the connected components so the same problem does not get mistaken for a boiler failure.
Clear repair advice
You receive a clear explanation of the fault, the work needed and the cost before anything starts. If replacement is the sensible option, we explain why and outline the alternatives.
A Clear Repair Plan for Your Boiler
Once the repair is approved, we fit suitable parts, test combustion, pressure and safety controls, and check the heating circuit. We explain any remaining limitations, leave operating instructions, and provide relevant paperwork for your records.
Pressure Loss and Leaks Traced
If the pressure keeps dropping or water is appearing around the boiler, we trace the fault before recommending a repair. You’ll know whether the cause is the boiler, a valve, a radiator or hidden pipework.
Gas Repairs Completed Safely
A gas boiler fault needs work by a Gas Safe registered engineer. We check the appliance and its safety controls, so the repair does not leave an unsafe condition behind.
Oil Boiler Repairs for Off-Grid Homes
Oil-fired boilers need different checks from gas appliances. Our OFTEC-registered engineers understand burners, fuel supply and controls on properties that aren’t connected to the gas grid.
Repair Details Kept Clear
You receive a written quotation before approved work starts, with the repair explained in plain terms. The final paperwork records what we found and what we carried out.
Questions to Ask Before a Boiler Repair
Is my boiler suitable for repair?
Tell us the boiler make and model, fault code, symptoms, fuel type and property location. A photograph of the boiler and controls can help us prepare accurate advice before attendance.
How much will my boiler repair cost?
Once we identify the fault, we provide a written quotation covering labour and suitable parts before work starts. You can approve the repair with the full cost clearly set out.
What does a boiler repair include?
For a heating fault, repair covers fault-finding, access to the boiler and connected controls, removal of failed components, and checks that the system operates safely before we leave the property.
How long does a boiler repair take?
Repair time depends on the fault, boiler access and whether the correct part is available. We explain the work before starting and tell you if a further visit is needed.
What information do you need before arranging a boiler repair?
Please share the boiler’s location, access arrangements, recent changes or repairs, and any visible leaks or unusual noises. We use these details to plan safely and bring the right equipment.
What to Expect From Your Boiler Repair
If you smell gas, switch off the supply if it is safe to do so, open doors and windows, and avoid electrical switches or naked flames. For other faults, tell us the boiler make, fault code and symptoms so we can prepare for the visit and avoid unnecessary disruption.
Some faults are uneconomical to repair, especially on an older boiler. We’ll explain the options clearly, including any parts that need ordering, so you can choose between repair and replacement with the likely disruption and cost understood.
A qualified engineer for the right boiler
Your boiler may be gas-fired, oil-fired or part of an older heating system. We send an engineer with the registration and experience needed for that type of work.
Gas Safe and OFTEC registered engineers
Gas boiler repairs are carried out by Gas Safe registered engineers, as the law requires. For oil-fired boilers, OFTEC registration covers the work. Our engineers are directly employed, and many have more than ten years’ experience with heating systems in older and off-gas-grid homes.
Clear costs before repair work starts
A fault can involve a small component, a difficult-to-source part or a larger repair. We explain the likely cost and options before starting the work.
No surprise charges
You receive a written quotation before repair work begins. If the fault changes once the boiler is opened up, we explain what we have found and agree the next step with you. You can then compare the repair cost with replacement where that is the more sensible choice.
Parts, access and disruption explained
Some repairs need a part that is not immediately available, while others involve draining the heating circuit or moving access panels. We tell you what the job involves before you approve it.
A practical repair plan for your home
Your boiler location, flue route and heating layout affect how we carry out the repair. We identify any access requirements and explain if heating or hot water will need to be isolated during the work. Once the repair is complete, we test the system and leave the area tidy.
Safe testing after the repair
A boiler should not simply restart and get left running. We check that the repair has resolved the fault and that the appliance operates safely.
Checks before we leave
We test the boiler’s combustion, pressure and safety controls, then check the heating circuit for correct operation. If a limitation remains, such as a weak pump or an ageing control, we explain it clearly so you know what may need attention next.
When replacement is more sensible
An older boiler may be repairable but no longer worth the cost of repeated parts and labour. We give you a straightforward view rather than recommending work that is unlikely to represent good value.
Repair or replacement advice
Your boiler’s age, condition, fault and available parts all affect the decision. We explain the immediate repair option alongside replacement where appropriate, including the likely disruption and cost of each. If replacement is chosen, our Gas Safe or OFTEC registered heating engineers can plan the work around the existing system.
When the assessment is complete, you’ll have a clear route forward: approve the repair, arrange a return visit for a part, or consider replacement if the boiler is no longer worth repairing. We’ll leave you with the information needed to make that decision without committing to work you haven’t approved.
To arrange the assessment, contact Alderminster Group and tell us what the boiler is doing. We’ll take it from there and keep the next step clear.
