About the new Worcester Bosch boiler range

Worcester-Bosch is the UK's leading boiler and heating manufacturer.

Worcester's quality is relentlessly award-winning, with over a decade of Which? Best Buy awards for their high-efficiency condensing boilers. Leading in every aspect, starting from game-changing boiler aesthetics to marketing leading boiler efficiency levels with impeccable after-service upheld through their unwavering 'Worcester-Bosch guarantee', they're the boiler brand putting all others to shame in the UK.

Covering every boiler installation type, Worcester has a high-quality boiler for every home and budget. Ranging from the Worcester-Bosch 2000, which delivers high efficiency at budget-boiler pricing, to the Worcester-Bosch 8000, which offers industry-leading efficiency and heating technology - there's a Worcester for every UK homeowner. To take full advantage of Worcester's famous customer service, ensure you choose an installation partner offering the full 10-year warranty.

How much do Worcester Bosch boilers cost?

For a standalone Worcester Bosch boiler, prices can range from £700 - £2,000 and are available in a wide range of sizes. However, it's worth bearing in mind that these prices don't include Gas-safe installation or any additional labour. With a Gas-Safe installation, you'll be looking at £2,050 - £3,900. And, at Heatable, we can fit your Worcester Bosch boiler in as little as 24 hours.

How much can a Worcester Bosch boiler save you?

This will depend on the efficiency of your current boiler and the new boiler you're searching for, but a Worcester Bosch boiler could save you as much as £540 per year if you upgrade from an old G-rated boiler to a modern A-boiler.

Which Worcester Bosch boilers are available?

We stock a wide range of Worcester Bosch boilers, including everything from combi, system and even heat-only. We even have a range of different heat outputs - from 12kW to 40kW - so you'll find the perfect heat for your home.

We're a Which? Trusted Trader which means we have to work to their strict standards and guidelines. We're Gas Safe Registered, and so are all of the installers who fit for us. Additionally, we back our workmanship with a comprehensive 24-month installation warranty.

How long should a Worcester Bosch boiler last?

Worcester Bosch boilers are designed to have a lifespan of around 10 to 15 years, but there's no reason they can't last longer if they are serviced and maintained.

How long is a Worcester Bosch guarantee?

For most boilers offered by Worcester Bosch, the guarantee is 10 years, except for the entry-level Worcester Bosch 2000 which comes with a 7-year guarantee as standard.
