Cost Of Moving A Boiler 2025 – How Much Is It To Relocate a Boiler?

Do you dislike the location of your gas boiler? While relocating a boiler can be a smart move, boiler relocation costs often make people hesitate.

Most combi boilers are installed in kitchens, but this isn’t always the best use of space. A modern condensing boiler can be moved to a bathroom, attic, or bedroom.

If you want to move a new boiler, the cost ranges from £800 to £3,800, primarily due to labour expenses. There are many factors that will affect the cost of a new boiler with relocation, some of which include whether it is an old or new boiler and how far from its original location you want to move it.

These jobs typically take 2 – 4 days, and time and costs vary depending on the complexity of the work. 

But if you want to move your existing boiler, this guide will help you calculate the cost of moving your boiler while also weighing the pros and cons of how it impacts your central heating system.

How Much Does It Cost To Move An Existing Boiler In Your Home

It is possible to move an existing gas boiler at any time, with costs ranging from £500 to £800 depending on various factors, like if you need a new boiler flue, the cost of copper pipe, and other materials and fittings.

However, if your boiler has been in use for more than 10 years, it will most likely need to be replaced soon. In such cases, moving an old boiler can sometimes almost equal the cost of installing a new one—unless you are moving it a short distance, such as within the same room.

Still, if your boiler is relatively new, under warranty, and in good working condition, moving it may be a practical option. This is especially true if you are planning larger construction work or redesign in your home.

Here’s a breakdown of the average costs of the materials required for moving an existing boiler:

Material	Average Cost
New Boiler Flue	£70 – £150
Copper Pipe (per meter)	£10 – £20
Fittings and Joinings	£5 – £10 per fitting
Wall Brackets	£20 – £40
Labour Costs	£300 – £500

How much is it to move a combi boiler?

If you have a combi boiler, the moving cost will be lower as there’s only one unit to deal with. Expect to pay between £300 and £800 to move a combi boiler. Most modern combi boilers can fit in tight spaces like kitchen cupboards, making them versatile for relocation.

How much is it to move a system boiler?

Moving a system boiler typically costs more due to the additional hot water cylinder connected to the central heating system. This type of boiler relocation can cost between £500 and £1,000+. You could also consider converting to a combi boiler, but the extra cost to remove the hot water tank will add to the overall price.

How much is it to move a conventional boiler?

Conventional boilers are similar to system boilers, but they also have a cold water tank to consider during relocation. This means moving costs could be higher overall, ranging from £800 to £2,000+, depending on how far you want to move your boiler from its original location.

If you are changing to a combi boiler from a conventional boiler, you could also move it at the same time, potentially saving on overall costs.

Where Can I Move My Boiler To?

The type of boiler you have will determine where you can move it. Conventional boilers require more space for hot water cylinders and cold water tanks, so you’ll need to account for these storage systems. 

On the other hand, combi boilers are compact and self-contained, making them easier to relocate to smaller spaces.

Here are some of the most popular places to relocate a boiler:

• Utility Room
• Kitchen
• Loft/Attic 
• Airing Cupboard
• Bedroom
• Bathroom
• Garage

Remember, new boiler installation costs will vary from room to room.

What Is The Average Time It Takes To Move A Boiler?

Simple combi boiler replacements can be completed in a matter of hours. Moving a boiler from one location to another can take an additional day.

If the new location is on the opposite side of your house, the time will be longer. This is because the Gas Safe heating engineer will have to modify and possibly reroute the pipework.

The Pros And Cons Of Moving Your Boiler

Relocating a boiler can be a practical option to improve the functionality and aesthetics of your home, but it’s a decision that should be made carefully. Here are the key pros and cons of moving your boiler:

Pros

• Frees Up Space for Storage: By relocating your boiler, you gain valuable room that you can use for storage or other purposes, especially in smaller homes.
• Reduces Noise Levels: If your boiler is noisy, moving it to another room or floor can reduce disruptions in living or bedroom areas. However, this might be a good time to consider whether buying a quieter new boiler is a better investment.
• Improved Aesthetics: New boilers aren’t usually a stylish part of a home’s interior. Relocating it to a more hidden or less conspicuous area, like a utility room or loft, ensures it doesn’t clash with your decor.
• Easier Annual Boiler Service: Moving your boiler to a more accessible location can make it easier for engineers to carry out your annual boiler service. If the boiler is currently hard to access, it might take longer to service, potentially increasing your boiler service cost.
• Improved Water Pressure and Flow: If your current boiler is far from your water source, relocating it closer to that area can improve hot water flow, making showers and taps more efficient and convenient.

Cons

• High Costs: Moving a boiler can be expensive, particularly if significant pipework modifications are required. If your pipes run under tiles or floorboards, you may need to lift them during the process, which can add to the cost. In addition, a new boiler flue will cost extra, and wall drilling may be necessary to accommodate the relocation.
• Not Cost-Effective for Older Boilers: Moving an old boiler may not be worth the investment. Upgrading to a new boiler can improve energy efficiency and save on monthly energy bills, which might make installation in a new location a better long-term solution.
• Disruption During Installation: Depending on the location of the move, relocating the boiler can temporarily disrupt your home. Floors and walls may need alterations, and this process can take several days, particularly if extensive pipe rerouting is involved.
• Additional Fees for Compliance: When you move a boiler, you must comply with safety regulations, and any required updates to flues or gas lines to meet these standards can drive up costs.

We recommend consulting a qualified engineer to assess the feasibility of your move and ensure compliance with safety regulations.

Factors That Impact The Cost of Relocating Your Boiler

Relocating a boiler can have benefits, but it’s important to weigh those benefits against the potential costs and complexities. Also, your boiler must comply with the HSE’s Gas Safety (Installation & Use) Regulations 1998 for the move to be safe and legal.

Here are some key factors to keep in mind:

• Modern condensing boilers require a waste pipe that leads to a drain.
• Carpets or floorboards might need to be removed, lifted, and rearranged.
• Pipes might be required to be visible if you have concrete, stone, or tiles as your hard flooring.
• Concrete or tiled floors may require the pipework to run through the wall or ceiling.
• To protect a boiler in an outhouse, garage, or shed from freezing weather, it will require frost protection and insulation pipes.
• Boilers must meet minimum flue clearance requirements so they cannot be placed too close to doors or windows.
• If the boiler is to be installed in an attic, scaffolding might be necessary.
• Water might take longer to heat if the boiler is far from the taps.
• Safety regulations also apply to attic installations: They must be well-lit, accessible via a walkway, and easy to access.

Lastly, ensure the boiler’s new location allows for easy access. This is essential for regular maintenance, annual boiler services, repairs, and keeping the boiler functional and compliant with warranties.

Final Thoughts

Relocating a boiler can be a worthwhile investment, but it’s important to weigh the costs and benefits carefully. Combi boilers are the cheapest to move, costing as little as £300, while system and conventional boilers tend to be more expensive due to extra components. 

Moving a boiler within the same room is usually the least costly while moving it to a loft or a completely different part of the house is more expensive and can reach up to £2,000 or more.

FAQs

Can I move my boiler myself?

No, relocating a boiler yourself is illegal and unsafe. By law, all gas work must be completed by a Gas Safe registered engineer. DIY relocation can lead to serious risks, including gas leaks, carbon monoxide poisoning, and voided warranties. 

It may also invalidate your home insurance. Boiler relocation is a complex process involving gas, plumbing, and electrical work, so always hire a qualified professional to ensure the job is done correctly and safely.

Do I need planning permission to move my boiler?

In most cases, planning permission isn’t needed to move a boiler inside your home, but the work must comply with building regulations. 

If a new boiler flue is needed, it must meet strict placement requirements, such as being a safe distance from windows or property boundaries. 

If you live in a listed building, leasehold property, or new build, you may need additional consents or permissions. External changes to your home, such as relocating the flue, may also require approval. 

When in doubt, consult your local planning authority and your installer, who should be familiar with all relevant regulations.
