Frequently Asked Questions about Boiler Installation


Share This Post

Boiler installation is an essential aspect of home or building construction. A boiler is an appliance that heats water or other fluids, which then circulate through pipes to provide warmth and hot water for both residential and commercial spaces. 

If you’re considering installing a boiler, you may have some questions in mind. In this article, we’ll answer five frequently asked questions about boiler installation.

What Type of Boiler Should I Install?

The most common types of boilers are conventional, combi, and system boilers. A conventional boiler is the traditional type of boiler that requires a separate cylinder to store hot water. A combi boiler, on the other hand, is a compact boiler that doesn’t require a separate cylinder. It heats water on demand, making it ideal for small spaces. 

A system boiler is a boiler that works with a separate hot water storage tank but doesn’t need a coldwater tank. The type of boiler you should install depends on your household’s hot water and heating needs, the size of your property, and your budget.

Do I Need Planning Permission to Install a Boiler?

In most cases, you don’t need planning permission to install a boiler. However, if you’re planning to install a boiler in a listed building or a conservation area, you may need to seek permission from your local authority. 

Also, if you’re installing an external boiler, you may need to comply with certain regulations, such as ensuring that the flue is not visible from the street.

How Much Will It Cost to Install a Boiler?

The cost of installing a boiler varies depending on several factors, such as the type of boiler, the size of your property, and the complexity of the installation. 

A new boiler installation can cost between $3000 to $8000. However, this cost may increase if you need to install additional pipework, radiators, or a hot water cylinder. It’s essential to get quotes from several boiler installation companies to compare prices and choose the most cost-effective option.

Do I Need to Powerflush My Heating System Before Installing a New Boiler?

Powerflushing is a process that involves cleaning your heating system by flushing out any debris, rust, or sludge that may have accumulated over time. 

Although it’s not a legal requirement to powerflush your heating system before installing a new boiler, it’s highly recommended. Powerflushing helps improve your new boiler’s efficiency by ensuring that the heating system is clean and free from any blockages. It also helps prolong your new boiler’s lifespan by reducing the risk of breakdowns and repairs.

Can I Install a Boiler Myself?

Boiler installation is a complex process that requires technical expertise and experience. Therefore, installing a boiler yourself is only advisable if you’re a Gas Safe registered engineer. 

Attempting to install a boiler without the necessary skills and knowledge can be dangerous and may result in severe injury or even death. It’s essential to hire a qualified and experienced boiler installation company to ensure that your boiler is installed correctly and safely.


Boiler installation is an essential aspect of home or building construction. Choosing the right type of boiler, seeking planning permission, getting quotes, powerflushing, and hiring a qualified engineer are some of the crucial factors to consider when installing a boiler. If you need clarification on any aspect of boiler installation, it’s essential to seek advice from a professional.
