Reliable, Energy-Efficient Gas Boiler Installations

When your old boiler is constantly breaking down or costing a fortune to run, it is time for an upgrade. At Neath Gas Services, we specialise in fitting high-quality, dependable mains gas boilers and full central heating systems tailored to your home.

With over 20 years of experience serving Neath, Port Talbot, Swansea, Bridgend and the surrounding valleys, our Gas Safe registered engineers ensure a professional, tidy, and compliant installation every time.

Why Upgrade Your Boiler?

Many older boilers, especially 1980s back boilers, are adapted onto outdated systems and run at a maximum of 70% efficiency. This means for every £1 you spend on heating, 30p is lost.

Modern upgrades make an immediate difference to your home and your wallet:

Feature	Old Standard Boilers	New A-Rated Boilers
Efficiency	~70% (High heat loss)	Up to 97% (Sedbuk A-rated)
Running Costs	High monthly gas bills	Can save up to 30% on bills
Reliability	Prone to frequent breakdowns	Built with advanced technology
Hot Water	Waiting for the tank to heat	Instant hot water (Combi models)

The Neath Gas Difference: Stop Paying for Boiler Insurance

Why pay monthly for boiler insurance when you can have guaranteed peace of mind for free?

We supply and fit premium boilers starting from just £1,500. Every new boiler we install comes with a robust 5 to 10-year manufacturer warranty. This protects your investment for a decade of cosy warmth and hassle-free maintenance, covering your parts and labour without the unnecessary insurance premiums. Choose wisely, choose a long-term solution.
