Our Gas Safe engineers are highly experienced and install only premium brands such as Worcester Bosch, Vaillant and Baxi — all with full warranty registration and guaranteed aftercare.

      We’re rated 5 stars by over 500+ local homeowners and were awarded Wales Heating Installer of the Year. With clear pricing, fast response times, and ongoing boiler cover options, you get a dependable, personal service from a company that genuinely cares about your home.

      How long does it take to install a replacement boiler?

      Most boiler replacements are completed the same day.
      Combi-to-combi swaps usually take 1 day, while system conversions or new pipework may take a full day or slightly longer.

      Before installation, we carry out a full assessment to ensure the boiler is correctly sized, compliant, and ready for efficient operation.

      How much does a new combi boiler cost?

      A new, A-rated combi boiler typically costs £1,800–£3,000, depending on:

      • The boiler brand

      • System type (combi, system or regular)

      • Installation complexity

      • Any required upgrades (flue, filters, pipework)

      All quotes include Gas Safe installation, warranty activation, benchmarking and system protection.

      What’s involved in a new boiler installation?

      Your installation includes:

      • Full system inspection

      • Removal of your old boiler (if required)

      • Fitting the new boiler + flue

      • Correct gas pipe sizing

      • Magnetic filter installation

      • Powerflush or system cleanse

      • Warranty registration

      • Benchmark certification

      • System setup and handover

      We ensure everything is safe, compliant and running efficiently before we leave.

      Do you install all boiler brands?

      We focus on the UK’s most reliable manufacturers:

      • Worcester Bosch

      • Vaillant

      • Baxi

      • Ideal 

      • Viessmann

      These offer long warranties, excellent parts availability and strong efficiency ratings — ensuring long-term reliability for your home.

      Warranty Questions Answered

      What Makes Blue Flame Different From National Boiler Companies?

      Unlike the big national companies:

      • We’re local, so you get faster response times

      • We’re family-run, not corporate

      • You get genuine aftercare, not call-centre support

      • You’ll deal with the same friendly engineers who know your area

      Local service. Professional standards. Better experience.

      Yes — Blue Flame offers flexible boiler cover plans, all managed locally by our own engineers. Plans include:

      • Annual boiler service

      • Priority breakdown support

      • Heating, plumbing & electrical cover (selected plans)

      • No hidden fees or call-centre delays

      Complete peace of mind from a local company.

      Do you repair boilers as well as install them?

      Absolutely. We repair all major boiler brands and carry common parts for Worcester, Vaillant and Baxi. If a boiler is beyond economical repair, we provide honest advice and a free replacement quote.

      Cardiff, Newport, Pontypridd, Porth, Caerphilly, Bridgend, Llantrisant, Rhondda Cynon Taf & surrounding areas.

      Blue Flame Warranty™ – Top Questions Answered

      What is the Blue Flame In-House Warranty™?

      The Blue Flame Warranty™ is your local, engineer-backed boiler warranty — designed to give you better protection than national companies.
      It includes:

      • 12 months of free aftercare

      • Priority breakdown response

      • No call centres — you speak directly with our South Wales team

      • All callouts handled by Blue Flame engineers

      • Manufacturer parts supplied where needed

      • Warranty stays valid with annual Blue Flame servicing

      This is one of the strongest local warranties available and a major reason homeowners choose Blue Flame over national brands.

      Do I need to service my boiler yearly to keep my warranty?

      Yes. All manufacturers require annual servicing to keep the warranty valid. The same applies to the Blue Flame Warranty™. Annual services maintain boiler efficiency, safety, and long-term reliability.

      Your first service is included free of charge in your Silver Cover aftercare. After year one, you can continue your protection from £6.99/month.

      What are the benefits of having an in-house warranty instead of relying only on manufacturers?

      An in-house warranty gives homeowners faster, clearer and more reliable support. With most manufacturers, you’re routed through call centres, scheduled into national queues, and often left waiting days for an engineer.

      With the Blue Flame Warranty™, all aftercare is handled directly by our local engineers, meaning quicker response times, one point of contact, and much less hassle. We diagnose faults, attend breakdowns, and only involve the manufacturer when a replacement part is required.

      This gives you the reliability of a manufacturer warranty, but with the speed and service of a trusted local company.

      Does the Blue Flame Warranty™ prevent blame-shifting between manufacturers and installers?

      Yes — and this is one of its biggest advantages. With national installers, it’s common for manufacturers to blame the installer, and installers to blame the manufacturer, leaving homeowners stuck in the middle.

      This removes that problem completely. We handle everything internally: diagnostics, callouts, communication, and arranging parts. If it’s an installation issue, we fix it. If it’s a boiler issue, we fix it.

      There’s no finger-pointing, no confusion, and no delays — just a clear, accountable team that takes full responsibility for your boiler’s performance.
