A combi boiler is a popular choice for most homeowners, as it provides both hot water and central heating in one compact unit. However, one of the biggest questions that homeowners have when considering a combi boiler installation is: how much will it cost?
Combi boiler install cost
The cost of installing a new combi boiler can vary widely, with estimates ranging from nearly £1,000 to £6,000, depending on the work required and the company you choose for the installation. To avoid unexpected costs and ensure a successful installation, it is important to get a fixed price quote in advance, and to choose a company that offers a warranty, includes a magnetic boiler filter and a system flush, and has positive customer reviews.
What makes up the cost of a combi boiler install?
The cost of a combi boiler installation can vary depending on several factors, including the type of boiler you choose, the size of your property, and the complexity of the installation. we will explore some of the key factors that can affect the cost of a combi boiler installation in the UK in more detail, and provide some rough estimates of what you can expect to pay.
Type of Boiler
The cost of a combi boiler can vary depending on the make and model you choose. Basic models can start from as little as £500, while high-end models can cost up to £2,000 or more.
It’s important to note that while a basic model may be cheaper to purchase, it may not be as energy efficient or have as long a lifespan as a higher-end model. Additionally, some boilers come with additional features such as smart controls, which can increase the price. Also consider the long-term costs and benefits when choosing a boiler.
Property Size
The size of your property will also have an impact on the cost of a combi boiler installation. A small flat or apartment will typically require a smaller, less powerful boiler, which will be cheaper to install.
Larger properties with multiple bathrooms will require a larger, more powerful boiler, which will be more expensive to install. Additionally, the number of bedrooms and the type of heating system in the property (e.g. underfloor heating) can also affect the cost of installation.
Complexity of Installation
The complexity of the installation will also have an impact on the cost. A straightforward installation in a property with existing pipework and a suitable location for the boiler can be completed in a day.
However, if the installation is more complex, for example, if the property does not have existing pipework or the location for the boiler is not suitable, the installation may take longer and be more expensive.
For instance, if the boiler needs to be installed in a location where there is no current gas supply, a gas line will need to be run to that location, which can add to the cost. Similarly, if the property has multiple floors or the existing pipework is outdated, the installation may require additional work, which can increase the cost.
Additional Costs
Other factors to consider include the cost of any additional components such as a flue or a programmer, and the cost of any building work that may be required. Additionally, if the boiler is being replaced, the cost of disposing of the old boiler should also be factored in.
Also, if the installation includes upgrading the current central heating system such as replacing radiators, it will add to the cost.
As a rough guide, the cost of a combi boiler installation can range from £1,500 to £3,500, depending on the factors mentioned above. However, it is always best to get a quote from a qualified and experienced heating engineer to get a more accurate estimate for your specific installation.
The cost of installation can also vary depending on location, for example, a heating engineer in London may charge more than one in a rural area.
How much is a new boiler fitted?
The cost of a new boiler fitted can vary depending on a number of factors, such as the type of boiler, the size of your property, and the complexity of the installation.
A basic combi boiler can start from around £500 to £800, while a high-end combi boiler can cost £1,500 to £2,000 or more. These prices are just for the boiler itself and do not include the cost of installation.
The cost of installation can range from £1,500 to £3,500, depending on the size and complexity of the job. For a straightforward replacement of an existing boiler, the cost of installation can be around £1,500 to £2,500.
However, if the installation is more complex and requires additional work, such as running new gas pipes or upgrading the central heating system, the cost can increase.
Replacing an old boiler with a new one and moving its location
Replacing an old combi boiler with a new one and also moving its location in a 3 bedroom semi-detached house can be a bit more complex and therefore more expensive than a straightforward replacement of an existing boiler. Here are some factors to consider and costs to keep in mind:
- Type of Boiler: The cost of the new combi boiler will vary depending on the make and model you choose. A basic model can start from around £500 to £800, while a high-end model can cost £1,500 to £2,000 or more. It’s important to consider the long-term costs and benefits when choosing a boiler.
- Location of the new boiler: Moving the location of the boiler can add additional costs to the installation. If the new location is in close proximity to the existing one, the costs may not be significant. However, if the new location is farther away and requires running new gas pipes, the costs can be higher. Additionally, if the new location of the boiler requires additional structural work such as creating a new boiler room, the costs can be even higher.
- Upgrading the central heating system: If the existing central heating system is outdated or in poor condition, it may be necessary to upgrade it as part of the installation. This can include replacing radiators, upgrading the thermostat, or adding additional zones for better temperature control. These upgrades can add to the overall cost of the installation.
- Building Regulations: Building regulations will need to be adhered to when moving the location of the boiler. This will involve obtaining Building Regulation approval, which can add to the cost.
As a rough estimate, the cost of replacing an old combi boiler with a new one and also moving its location in a 3 bedroom semi-detached house can range from £3,000 to £5,000. This will depend on the specific factors mentioned above such as the type of boiler and location, and the complexity of the installation.
It’s always best to get a detailed quote from a qualified and experienced heating engineer, who will be able to provide a more accurate estimate based on your property and requirements.
Changing from a regular or system boiler to a combi boiler
The cost of changing from a regular or system boiler to a combi boiler can vary depending on several factors, including property size, the complexity of the installation, and type of combi boiler. As a rough estimate, the cost of changing from a regular or system boiler to a combi boiler can range from £2,000 to £4,500.
Summary
It’s important to not just consider the upfront cost, but also the long-term costs and benefits of the boiler you choose. Additionally, it’s important to make sure the heating engineer you choose is Gas Safe registered and has the appropriate insurance and qualifications to carry out the installation.
By taking the time to consider all of these factors and getting a detailed quote, you can make an informed decision about the cost of a combi boiler installation and ensure that you choose a boiler that is right for your home and budget.
