How it works

Step 1: Tell us your needs

First up, you’ll need to answer some straightforward questions to help us understand your new boiler needs. This will include the type of boiler you currently have and want, details about your home (for example, size and type), as well as where you’re located.

Step 2: Time to hand-pick

Next up, you’ll be displayed with a range of high-quality boilers that are suitable for your specific home, where you can select which fixed-price boiler best suits your needs and budget. Quality is a priority for us, so you’ll only be able to choose from our most trusted brands, such as Worcester Bosch and Vaillant.

Step 3: Our experts get to work

Once we know which boiler you’ve picked, you’ll need to send some quick pictures of your heating system so we can source all the materials required to fit your new boiler within 48 hours. Your trusted boiler expert will then fit your brand new boiler safely and with precision.

What our clients say

  • I’ve had issues with central heating system since buying the house 9 ago and have around 16 rads. He basically over hauled the system, flushed it, new heat exchange and it works like a dream. All rads heat instantly now. Always available to chat and support in case any issues - highly recommended. Great to have a reliable, honest expert locally.
