Expert Boiler Installations in South London
At OJ Gas & Heating, we provide professional and reliable boiler installations in South London, helping homeowners and landlords upgrade to energy-efficient systems that save money, reduce emissions, and keep your home warm all year round.
New Boiler Installations That Save You Money
If your current boiler is over 10 years old, chances are it’s running inefficiently, and costing you more than it should.
Modern condensing boilers are up to 90–94% efficient, compared to older models which may only convert 60% of fuel into heat. That’s a huge difference, and switching could save you £300–£400 per year on your energy bills.
Our team specialises in installing a wide range of leading boiler brands, including Vaillant, Worcester Bosch, Ideal, Baxi, and Glow-worm. Whether you’re upgrading a combi boiler, switching from a system boiler, or installing a completely new central heating system, we’ve got you covered.
