Got a question? We’re here to help
Here are some of the questions we’re asked most often
Why should I have a filter fitted?
Many boiler breakdowns occur are due to sludge in the heating system. Find out the many benefits of fitting a magnetic filter & how it can save you money.
How often should I service my boiler?
You should have your boiler serviced once a year. Regular servicing and maintenance help prolong the life of your boiler, keep it running efficiently, and ensure it’s safe to use. It can also help maintain your manufacturer warranty.
Which boiler brands do you install?
We fit a range of leading brands including Baxi, Worcester Bosch, Vaillant, and Ideal. Baxi features most often in our installations because of their reliable range and up-to-10-year warranty options, but we will always recommend the best fit for your property, boiler size, and budget.
How long does it take to install a new combi boiler?
Most new boiler installations are completed in one day, depending on your existing system and location. We’ll always let you know what to expect before we start.
What are the signs my boiler needs replacing?
If your boiler is over 10 years old, or struggles to heat your home efficiently, it might be time to consider a replacement. We’ll assess your system and give honest advice on whether a repair or replacement is best.
What does a Baxi boiler warranty cover?
The boiler warranty covers the boiler and integrated controls. However, if the boiler fails due to an external issue, such as incorrect installation or sludge in the system, this is not covered by the warranty, and a charge will be incurred for replacing the damaged or blocked components.
