How Much Does Moving A Boiler Cost?

Thinking about moving a boiler to a new location in your home? Here’s everything you need to know…

Why Move A Boiler?

Unfortunately, boilers are not always installed in the most convenient places and many homeowners take the decision to move their boiler for a variety of reasons. Usually, it will be to free up space in a room or to improve the comfort or aesthetics of their home.

For example, a boiler in a kitchen cupboard could be taking up valuable storage space or a boiler in a bedroom could be a noise disturbance during the night. Depending on the layout of your home, relocating the boiler could also result in a faster response to hot water demand. And, of course, a boiler is rarely considered an asset to a room’s interior design, especially if there is exposed wiring or pipework alongside it.

What’s the Cost of Moving A Boiler?

On average, moving a boiler could cost from £300 to £800. However, this figure will be impacted by several factors and, as you might expect, the more complex the move the more expensive it will be.

Materials Average Cost
Boiler flue £70 – £120
Extension flue pipe / flue bends £40 per metre
Magnetic filter £100 – £120
Controls £70 – £650
Pipework / fittings £300 – £600

If you decide to combine the move with the installation of a new boiler this will add to the cost. New Combi boilers tend to cost anything from £700 – £2,500. Labour costs will vary from installer to installer.

Moving a boiler just a few feet will be considerably cheaper than relocating it to a new room because of the extra materials needed and the engineer’s labour.

  • The further the boiler is moving, the more copper pipework will be needed.
  • Additional flues or extensions may be needed e.g. if the flue is currently coming out the side of a wall horizontally and you’re moving it to the attic you will need a vertical flue instead.
  • Floorboards may need to be lifted and relaid.
  • It may be necessary to drill through and then patch holes in walls for the pipework.
  • It’s also worth noting that oil boilers are considerably heavier than gas or LPG; this may mean more than one engineer is needed to move it which could also increase costs.

    In cases where moving an existing, older boiler is likely to cost £500-£800 or even more, it may be more advisable to consider replacing it with a new, more energy efficient model.

    Where Can I Move a Boiler to?

    A Combi boiler can be relocated by just a few feet or to a completely different room such as the kitchen, utility room, attic, basement, garage, bathroom or even a bedroom. In the case of System boilers and Regular boilers there may be more restrictions on where it is installed as they have more elements to incorporate. System boilers need a hot water storage cylinder to be able to provide hot water for your taps; this large cylinder is often kept in an airing cupboard. A Regular boiler system includes both the storage cylinder and a feed and expansion tank which needs to be kept in the attic above the boiler.

    Should I Relocate My Current Boiler or Replace it with a New Boiler?

    If your current boiler is only a few years old and still covered by a warranty then buying a new model is not usually recommended.

    However, if your boiler is over 8 years old, inefficient, developing faults or it’s likely it will need to be upgraded in a couple of years, a replacement may be the better option long term. New, energy efficient boilers are available for as little as £750 (excluding installation) and include lengthy warranties. This option becomes even more attractive when you consider that replacing an inefficient boiler with an A rated version can greatly reduce energy bills. This can be by as much as £350 per year, so in some cases a new boiler will pay for itself in just a couple of years through reduced energy bills.

    Another reason to consider a replacement boiler rather than relocating an old one is the availability of flue parts. If your boiler is no longer in production it may be difficult to find the right flue and so relocating it may not be an option.

    If you currently have a System or Regular boiler, you may be able to replace it with a Combi. Combis are compact, all-in-one units which take their supply of water directly from the mains and heat water on demand. This means you will be able to remove the hot water cylinder and / or feed and expansion tank. The extra work involved may make the job more costly but it will free up space in your home. It’s important to note, however, that Combis aren’t really suitable for homes with more than one bathroom.

    Things to Consider Before You Move a Boiler

    If you decide that moving your existing boiler is the best option, your next step will be to settle on a suitable new home for it. It might be as simple as moving it to a new place in the same room, but there are some key factors to consider:

  • If you have concrete or tiled floors pipework may need to be run through a wall or the ceiling.
  • Boilers have minimum flue clearance requirements which means they can’t be positioned too close to windows or doors.
  • Carpets and floorboards may need to be disturbed, lifted and relaid.
  • If you are moving the boiler further away from taps, you may notice your water takes longer to heat up.
  • A boiler installed near a drain needs a waste pipe.
  • Scaffolding may be required if the boiler is being installed in an attic. There are also safety regulations which mean your attic must be well lit, have a walkway and easy access such as a ladder.
  • Remember that a boiler in an outhouse or garage will need frost protection and insulated pipes to protect it in cold weather.
  • If your boiler is a bit of an eyesore in your home it’s sometimes possible to build a cupboard or unit around it to disguise it. You can either do this yourself or find a carpenter.
  • IMPORTANT: Wherever you move your boiler to, make sure it is still accessible for future servicing or repairs.

    Is it Safe to Install a Gas Boiler in a Bedroom?

    You can install a gas boiler in a bedroom as long as the boiler is ‘room sealed’. This means that it takes air in from the outside and expels it outside, so no fumes enter the home.

    Some homeowners are reluctant to install a boiler in a bedroom because of safety concerns. In reality, it’s perfectly safe to operate modern room sealed boilers in a bedroom provided they have been installed correctly by a Gas Safe registered engineer. Of course, any faulty boiler can leak carbon monoxide. A carbon monoxide leak is potentially fatal so regular servicing and a carbon monoxide detector are recommended no matter where you install your boiler.

    Before you settle on installing the boiler in a bedroom, it’s worth considering that even modern boilers make some noise when operating which isn’t ideal in a room where people are sleeping.
