Lost your heating? Let's find out why.
Boiler and heating repairs for homes across South West London. Recognise any of these symptoms? Book a visit or call. Our Gas Safe registered engineers will diagnose the fault and talk you through it clearly.
Speak to us about a repair
Not sure what is wrong? That is fine. Describe what is happening and we will take it from there.
No heating or hot water
A cold home or cold taps can have several causes. Tell us what you are seeing and an engineer will find the fault properly.
Boiler not firing
If your boiler will not light, shows a fault code or keeps locking out, leave the inside of the appliance to a Gas Safe registered engineer.
Boiler pressure issues
Pressure that keeps dropping or climbing often points to an underlying problem. We will diagnose why, not just reset it.
Radiators not heating properly
Cold spots, cold radiators or some rooms warmer than others. We check the whole system to understand what is holding it back.
Thermostat or control faults
Heating that will not respond, ignores the timer or runs when it should not. We test the controls and wiring to the boiler.
Boiler leaks
Water under or around the boiler should be looked at promptly. Do not open the casing. Call us and we will advise on next steps.
If you smell gas, leave the property and call the National Gas Emergency line on 0800 111 999. Please do not attempt repairs to gas appliances yourself.

Read about this serviceWhich boiler brands do you install?
We fit all boiler makes. Our commonly requested brands include Vaillant, Baxi, Ideal and Worcester Bosch, but the right recommendation depends on the property, hot-water demand and existing heating system.
Read about this serviceHow often should a boiler be serviced?
Most manufacturers recommend servicing a boiler once a year. Regular servicing supports safe operation, efficiency and any applicable manufacturer warranty conditions.
Read about this serviceIs a CP12 gas safety check the same as a boiler service?
No. A CP12 records the findings of the landlord’s gas safety check. A boiler service is maintenance of the boiler. They have different purposes, and a service does not replace a required landlord gas safety check.
Read about this serviceDo you offer commercial boiler installation in South West London?
Yes. Gas E Plumbing handles enquiries for commercial boiler installation and replacement across South West London. Share your building use, boiler details and heating requirements so we can confirm the scope and arrange a survey.
Read about this serviceCan a heat pump work with existing radiators?
Sometimes. Existing radiators must be assessed because heat pumps generally operate at lower flow temperatures than traditional boilers. Some radiators may need to be resized.
