Common boiler problems we investigate

  • No heating, no hot water or an intermittent supply

  • Repeated pressure loss or a leaking boiler

  • Problems with thermostats, timers and heating controls

We aim to repair where practical. If a replacement is worth considering, we explain why and help you compare the options.

Gas, oil and LPG boiler repairs

Our team works with the main domestic boiler fuel types. Tell us which system you have so we can arrange the appropriate engineer.

Gas boilers

Our Gas Safe registered engineers diagnose and repair gas boiler faults, including heating, hot water and control problems. We work on most major makes and models.

Oil boilers

Our OFTEC registered engineers provide oil boiler fault finding and repairs, with servicing available to help you look after the system afterwards.

LPG boilers

We also repair LPG boilers for properties without mains gas. Please tell us that your system uses LPG when you enquire, along with its make and model.

Southampton boiler repair questions

How soon can you arrange a boiler repair in Southampton?

Call 01794 765774 with your postcode and a description of the fault. We will discuss availability and the next suitable visit. For an urgent breakdown, calling is the best way to check availability.

Do you repair gas, oil and LPG boilers?

Yes. We repair gas, oil and LPG boilers, with Gas Safe registered engineers for gas work and OFTEC registered engineers for oil systems. Tell us the fuel type, make and model so we can confirm support for your boiler.

How much will a boiler repair cost?

The cost depends on the fault, the investigation needed and any replacement parts. Contact us with the boiler details and symptoms so we can explain the next step and any assessment or call-out charges before you book.

Should I book a boiler service or a repair?

If the boiler is faulty, losing pressure or not supplying heating or hot water, tell us before booking a routine service. A service is planned maintenance and does not automatically include fixing a fault. We can advise which appointment is appropriate.

Can an older boiler be repaired rather than replaced?

That depends on its condition, the fault and whether suitable parts are available. We aim to repair where practical and will explain if replacement is worth considering. Age alone does not tell us whether a repair is the best option.

Do you help landlords with boiler repairs and servicing?

Yes. We provide boiler repairs and servicing for Southampton rental properties. Let us know the property postcode, the problem and how access will be arranged. We also offer landlord gas safety checks, which are separate from a boiler service, so please specify the work you need.
