Frequently Asked Questions

Got a question about your boiler, our services or how we work? Here are the answers to some of the questions we hear most often from homeowners across Chesterfield, Dronfield, Sheffield, Barlborough and Mosborough.

1. Which boiler brands do you fit?
We fit boilers from Worcester Bosch, Baxi, Vaillant and Navien. These are some of the most trusted names in the industry and all come with manufacturer warranties.

2. How long does a boiler installation take?
A standard boiler swap in the same location typically takes between four and six hours. More complex jobs, such as a system conversion or a boiler relocation, may take longer. We will always give you a realistic timeframe before the work begins.

3. Do you offer finance for new boilers?
Yes. We offer flexible finance through Phoenix Finance, allowing you to spread the cost of your new boiler into monthly payments. Finance is subject to eligibility and approval. Speak to us for more details.

4. Will you dispose of my old boiler?
Yes. We remove and dispose of your old boiler responsibly as part of the installation process.

5. How long is the warranty on a new boiler?
Manufacturer warranties vary depending on the brand and model selected. We can advise on warranty lengths when helping you choose your new boiler.

1. How often should I service my boiler?
Your boiler should be serviced by a Gas Safe registered engineer every 12 months. Regular servicing keeps your boiler running safely and efficiently, helps prevent breakdowns and keeps your manufacturer warranty valid.

1. What is a powerflush and does my system need one?
A powerflush is a deep clean of your central heating system that removes sludge, debris and built-up deposits from your radiators and pipework. Signs that you may benefit from a powerflush include cold patches on radiators, noisy pipes, slow heating and frequent boiler breakdowns.
