Heating system upgrade in Swansea
Many homes in and around Swansea are older solid-wall properties, and coastal exposure makes wind-driven rain and damp a real consideration. In homes like these the boiler is rarely the only problem: pipework extended over decades, radiators sized before an extension was built, and controls that heat every room the same. An upgrade looks at the whole system so a new boiler isn't let down by the rest of it.
What the survey checks
Our Gas Safe engineers check the boiler, flue position, pipework and every radiator, and work out whether a combi, system or conventional boiler suits how much hot water the household uses. Swansea is covered by the same in-house team that works across the West Midlands, with surveys arranged around our regular South Wales work.
Planning and building rules in Swansea
A like-for-like boiler replacement in Swansea doesn't need planning permission, but it must be notified under Building Regulations in Wales, which a registered Gas Safe engineer does for you. Moving the boiler or its flue can bring in extra rules, and we flag that at survey.
