new boiler quote.
My old boiler packed in on Monday night,I had a new one installed by 4pm Wednesday, I cannot really fault Next Level,Len was absolutely class,cleaned up and sorted everything out. First class company all round.



Next Level Boilers fitted us a new boiler. They were very prompt from quote to the finished job.They showed us how to use everything and even gave us two electric fan heaters to keep us warm while we waited for the new boiler. A very nice touch.



Really impressed with the quality of work. Len turned up on time he was friendly, knowledgeable and gave me faith that I was in good hands. The boiler was fitted in one day and he showed me how to use the new thermostat, how to top up the pressure and how to adjust the hot water temperature. These are a good choice if you need a new boiler.

Since Len fitted our new boiler we have had a reduction in our gas bill, this is due to the smart thermostat he fitted which gives us control of our heating when we aren’t even home.

Typically a boiler can be fitted in 1 day. If you are taking out an existing conventional boiler and fitting a combination boiler it can take 2 days.
We use strong magnets and chemicals to clean your existing pipe work and radiators prior to fitting your new boiler. This is called a chemical clean. We also fit a magnetic filter on every install to protect your boiler going forwards.
If possible please ensure we have full access to your boiler, gas meter and radiators. We can always help moving your belongings if necessary.
We are suitable for landlords, we issue Gas Safety Certificates with every install if requested prior to installation.
