What our customers say

Buy a boiler. Replace your radiators, too.

Replace up to 10 of your existing radiators with Stelrad’s new Compact series. We’ll install them during your boiler installation. We can only fit new radiators in place of existing ones, not in new locations.

Add radiators to your basket when choosing your boiler.

Boiler FAQs

BOXT only offer the best boiler brands, so when looking for a new boiler, we’d recommend looking through our range for peace of mind. The best brands of combi boilers for consistent quality include Worcester Bosch and Ideal. It’s also worth checking the energy efficiency rating to ensure your chosen boiler is not only good for the environment, but also helps you to save money in the long run.

What’s even better, is that with every purchase of a boiler from BOXT, you’ll have the option of choosing a Google Nest Learning Thermostat and a Google Home Hub to help you get the most out of your new appliance.

Anyone can get a new boiler if they feel they need an upgrade. However, it’s more cost effective to only upgrade your boiler if your current one is faulty, or if it’s over 10 years old. Constantly replacing faulty components can end up being much more costly than a complete system replacement, so an efficient upgrade is often the best option.

For brand new, quality boilers that deliver, browse our selection of Worcester Bosch, Heatline and Ideal boilers. We’ll even give you an extended boiler warranty with your purchase of any Worcester Bosch boiler.

We stock a range of gas boilers from reputable manufacturers including Worcester Bosch, Ideal and Heatline, by Vaillant. Each of these manufacturers are known for building energy efficient, A-rated systems that last. With BOXT, you can be confident your new gas boiler will last you for years to come.

Our qualified engineers can install a new boiler in your home as soon as tomorrow, subject to availability. Use our Find A Boiler tool to choose the best gas boiler for you and your home, and get it delivered and installed at your convenience.

Worcester Bosch are one of our most recommended boiler brands and we’re a proud partner. Over the past 50 years, they’ve built up a solid reputation for delivering energy efficient, reliable boilers to homes. If you’re searching for a new boiler but aren’t quite sure where to begin, our selection of Worcester Bosch boilers are a good place to start.

With each Worcester Bosch boiler, we’ll give you up to 10 years warranty and installation at a time that suits you, from one of BOXT’s Gas Safe Registered engineers. You’ll also get a Worcester Bosch boiler filter to keep your system running like clockwork.

A boiler replacement can be an investment for any homeowner or landlord, which is why here at BOXT, we keep our prices fixed, fair and as low as possible. For example, if you chose a Worcester Bosch 25i boiler with a horizontal flue and installation, we’ll charge a set price of £1,795, in the majority of locations. See how much better off you’ll be by getting a quote from us.

If you’re finding your boiler is being temperamental or regularly breaks down, you should seriously consider a replacement boiler. Use our Find A Boiler tool to find the best boiler deals for you based on your specific home requirements.
