New Boiler Installation & Replacement Bristol
L&P Heating installs high-efficiency boilers for homes, rental properties and businesses across Bristol and the surrounding areas.
We’ll assess your property’s heating requirements, recommend the right boiler for your needs and carry out a professional installation that’s built to deliver reliable heating for years to come.
Why Upgrade to a New Boiler?
Older boilers can be as low as G-rated and run at 60–70% efficient, while a new A-rated condensing boiler achieves 90%+ boiler efficiency. If your gas or LPG boiler was installed before 2005, it’s almost certainly less energy efficient than a modern condensing model – here’s what upgrading to a new A-rated condensing boiler can do for your home:
- Save money on your energy bills
- Improve your home’s energy efficiency
- Enjoy reliable heating and hot water
- Reduce the risk of costly breakdowns
- Benefit from a long manufacturer’s warranty
- Lower your carbon emissions
Should I Replace My Boiler?
Not sure if it’s time for a replacement? A few signs to look out for: it’s more than 10–15 years old, it’s breaking down more often or needs increasingly expensive repairs, your bills keep rising even though your usage hasn’t changed, it’s noisy, leaking or struggling to heat your home evenly, or it’s no longer covered by a manufacturer’s warranty. If any of this sounds familiar, or you’re simply ready for a new, more efficient boiler, our engineers can assess your current boiler and advise honestly on whether a repair or a full replacement makes more sense for your home

Our engineer will start by safely isolating your existing boiler from the gas and water supply before removing it.

It depends on your home and how you use hot water. Combi is the UK’s most popular choice — compact and efficient, providing hot water on demand — though it can struggle with poor water pressure or very high demand. System pairs with a cylinder, giving you a ready store while taking up less space than a conventional set-up, making it a good fit for larger households with multiple bathrooms. Conventional takes up the most space but is often the best option for older homes with traditional setups. Our engineers will recommend what suits you during your free home survey.
