Boiler Installation FAQs

How long does it take to install a boiler?

For most boiler installation, it should take about a day to complete. If you’re having additional work such as radiator replacements, pipe replacements or having the boiler relocated it will take longer.

How much does a new boiler cost?

On average a new boiler with JML Plumbing will cost around £1,900. The overall cost will ultimately depend on the boiler needed for your home. We’re able to offer much more competitive prices than other companies in Hampshire because we work directly with boiler manufacturers rather than 3rd party suppliers.

What is the best boiler?

Each boiler has it’s advantages & disadvantages, so the best boiler ultimately depends on the individual requirements of the property. We will typically recommend a Glow-worm, Vaillant or Ideal Heating boiler as in our experience are best for homeowners in Hampshire.

How long do I wait before getting my new boiler serviced?

We recommend getting your boiler serviced annually, so one year after your new boiler has been installed. We provide the first annual service free of charge for our newly installed boilers.

The JML Boiler Installation Process

When it comes to installing a new boiler, we find it can often be a stressful time for customers, so we aim to make the process as stress-free as possible.

  1. We help you find your perfect boiler – by using a calculation that determines the BTU/HR* Output requirements and boiler efficiency.
    • Using your house type to work out how much heat-loss your property is likely to experience
    • How many radiators your property has, and where they are located.
    • Hhow many baths your property has, as well as thermodynamic showers.
    • We also take into account your existing boilers fuel supply.
      • *BTU/HR = British Thermal Unit/Hour. How much heat your new boiler needs to output per hour!
  2. Once we have that calculation, we will also run through your existing boilers location and whether that is suitable for you or not.
  3. We’ll then be able to provide a quote for how much you’ll pay. It’s a fixed price quote so it won’t change!
  4. If you’re happy with the price, we’ll arrange a date for the installation to take place.
    • In most cases we can complete a boiler change in one day – so you won’t be without your hot water for too long.

On The Day

  1. We’ll arrive on the day with your new boiler, and everything we need to complete the replacement.
    • We even bring our own drinks, so no need to make us tea or coffee!
  2. We’ll start by switching off the fuel & water intake to the boiler, in most cases this does mean your property will be without water until the installation is complete.
    • We recommend filling up the kettle and ensuring you have a few bottles of water ready for the day.
  3. We then disconnect the existing boiler and double check the pipe infrastructure.
  4. We then install the new boiler, testing it a few times to make sure everything is working perfectly.
  5. Once we’re done, we’ll clean up any mess, take away your old boiler for recycling, and we’ll show you how to work your new boiler and some troubleshooting & maintenance advice.
  6. When you’re happy, we’ll sign off the new boiler!

Post-Completion

  1. We’ll then register your new boiler with the manufacturer to get your manufacturer warranty.
  2. We would love it if you provide us with a review!
