Boiler Replacement & Upgrades
Replace your old, inefficient boiler with a modern A-rated system across Wales and South West England. Lower bills, reliable heat, and full warranty—often at no cost with ECO4 grants.
Serving Swansea, Cardiff, Neath, Bristol, Bath, and surrounding areas
Why Upgrade Your Boiler?
Your boiler accounts for around 60% of your home's energy use. An old, inefficient boiler isn't just costing you money—it's working harder than it needs to, increasing the risk of breakdowns when you need heat most.
We install Ideal and Worcester boilers—trusted brands known for reliability and efficiency. Every installation is carried out by Gas Safe registered engineers across Wales (Swansea, Cardiff, Neath, Carmarthenshire, Pembrokeshire, Bridgend) and South West England (Bristol, Bath, Gloucestershire, Somerset), with full commissioning and handover.
What's Included:
- Full property survey and system assessment
- Removal and disposal of old boiler
- New A-rated condensing boiler installation
- System flush and magnetic filter
- Smart thermostat and controls
- Gas Safe certification and registration
- Up to 10-year manufacturer warranty
Understanding Your Warranty
ECO4-funded boilers come with a 2-year warranty as required under the scheme rules. This is separate from—and shorter than—the standard manufacturer warranty.
Manufacturer warranties (up to 10 years for Worcester and Ideal boilers) are available but typically require annual servicing by a Gas Safe registered engineer to remain valid.
We'll explain exactly what warranty applies to your installation at the point of handover.
Signs You Need a New Boiler
- Your boiler is over 10-15 years old
- Energy bills keep rising despite no change in usage
- Frequent breakdowns or repairs
- Uneven heating throughout your home
- Strange noises from the boiler
- Yellow flame instead of blue (safety concern)
- Radiators take a long time to heat up

Modern A-rated boilers are up to 94% efficient, compared to older models at 60-70%. That's real savings every month.

Quieter Operation
