How Much Does Moving A Boiler Cost?

Moving a Boiler

Boilers aren’t always installed in the most convenient of places and if you’ve taken the decision to move your boiler, you’ll need to think about the potential cost.

Typically, moving a boiler will cost £300 – £800 and take 1-2 days but this will vary depending on how far you want to move the boiler from its current location.

Why move a boiler?

For many homeowners, wanting to move a boiler comes down to freeing up space in a room, improving the aesthetics or making their home more comfortable. A boiler in a kitchen cupboard could be taking up valuable storage space while 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 and the labour costs will vary from installer to installer.

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.

Moving a boiler by only 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.

Where can I move a boiler to?

Another factor on the cost of moving a boiler is where it’s being moved to and how far that is from the current location. In theory, a boiler can be installed in many locations around the home:

  • Airing cupboard
  • Attic
  • Bathroom
  • Bedroom
  • Garage
  • Kitchen
  • Utility room

A combi boiler can be relocated into any of these locations or by just a few feet but in the case of system and regular boilers, there may be more restrictions on where they can be installed as they have more external parts in addition to the unit. 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 includes both the storage cylinder and a feed and expansion tank which needs to be kept in the attic, above the boiler.

Let’s take a look at some of the pros and cons of installing a boiler into each of these locations.

Airing cupboard

The airing cupboard tends to be where the hot water cylinder is installed as part of a central heating system with a regular or system boiler. This is because the heat that comes of the cylinder can keep your laundry dry.

If you have the cylinder removed and replace it with a combi boiler then the airing cupboard will no longer be as warm. If you’re set on having the boiler installed into the airing cupboard but also want your airing cupboard to work well then it’s often recommended to have a small radiator installed too.


Moving the boiler completely out of sight is a high priority for many when moving a boiler and there’s no better place than the attic. However, it might not be as straightforward as you hope.

First of all, if you have a regular boiler, a loft installation is unlikely to be possible as they rely on gravity to feed water from tanks in the loft down to the boiler – something that isn’t possible if they’re at the same level.

The boiler also needs to be easy for a heating engineer to access for servicing and any maintenance which might mean having to have some additional work done to your loft to get it up to standard. The loft will need to be easily accessible, well lit and have safe flooring.

Additionally, in the event of your boiler leaking, the water will drop downwards and could cause damage to other floors of your home.


One of the concerns around having a boiler in a bathroom is the combination of having an electrical appliance in a wet room. It is very much possible as long as the installation meets certain regulations that ensure the boiler is unlikely to get wet, can be accessed by a heating engineer and has suitable ventilation.

Typically, a boiler in a bathroom will need to be installed within a cupboard and a certain distance away from taps, showers and baths. Also, a boiler in a bathroom must be room sealed.

No matter where the boiler is being installed, it must be in a position where the flue meets Boiler Flue Regulations so that it can safely expel waste gases out of the home.


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.

The main concern with installing a boiler into a garage is the risk of freezing during the winter months.

During freezing temperatures, the water within a boiler can be susceptible to freezing. For this reason, it’s recommend to install a boiler with frost protection heating which will keep the water above a certain temperature. In addition, you should also have the pipes insulated with lagging.


The kitchen is one of the more conventional locations for boiler installation. And while they can often be hidden away in a cupboard or under a unit, this does mean that some kitchen storage space is lost.

Utility room

For homes that have a utility room, it’s the ideal area for keeping the boiler out of the way to save space elswhere around the property.


Will I need a new boiler or can I move my existing boiler?

An existing boiler can be moved to a new location but you’ll need to think about whether it makes sense at this point in time.

If your current boiler is only a few years old and still covered by a warranty then buying a new model doesn’t really make financial sense and if you can’t wait to change the location until you’re having a replacement installed then it is possible.

However, if your boiler will need replacing in a couple of years anyway, it would be a better idea to have a new boiler installed in the new location. Otherwise, you’ll be spending money to move your boiler then having to replace it soon after.

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 unit can greatly reduce energy bills 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.

How long does moving a boiler take?

A straightforward like-for-like boiler replacement can be done within a day – moving a boiler to a new location can add an extra day onto the work. Should the new location be a particularly long distance away from the current point of installation then this will add to the time as the heating engineer will need to add to and possible reroute the pipework.

Moving a boiler considerations

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 meaning 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
  • If you have hard flooring such as concrete, stone and tiles then pipes might need to be visible
  • Distance from taps as this will impact the time it takes for the hot water to travel (combi boilers)
  • Scaffolding may be required if the boiler is being installed in an attic
  • Attic installations also come with safety regulations: must be well lit, have a walkway and be easily accessible
  • A boiler in an outhouse or garage will need frost protection and insulated pipes to protect it in cold weather

IMPORTANT: Wherever you move your boiler to, make sure it is still accessible for future servicing or repairs.
