What are building regulations for boiler installation?
As a responsible landlord, it’s up to you to ensure the boilers in your rental homes are safe, working correctly and comply with building regulations. These regulations are in place to ensure boilers are correctly fitted and safe to use. Remember, a faulty boiler could cause damage to the home as well as injury to the occupants.
So, what are the building regulations for boiler installation? Well for starters, gas boilers should be installed by a Gas Safe registered installer who’ll follow building regulations. The engineer who installs the boiler should then notify your local authority through the Gas Safe Register in under 30 days. After this, a “Boiler Building Regulation Compliance Certificate” will be issued.
Building regulations for boiler installation
You may find one of your properties needs a new boiler if the old one breaks, becomes inefficient, becomes dangerous, or is simply outdated. While this is an extra cost, many boiler suppliers offer payment plans. Having a working boiler is vital to keep your tenants comfortable so it isn’t something you can ignore.
There’s a range of different building regulations for boiler installation including:
Hiring a qualified installer: Depending on the type of boiler you choose your engineer will need to be registered with the correct approved scheme. For example:
- Gas boilers should be installed by a Gas Safe Registered engineer.
- Solid fuel boilers and oil-fired boilers should be installed by an engineer registered under a Competent Person Scheme.
Following Approved Document J: Replacing a boiler needs to be done using the guidelines described in this document. This covers regulations for hearths, flues, air supplies and more.
Efficiency: New boilers should only be installed if they’re efficient. The regulations state that oil boilers should be at least 85% efficient and gas boilers should be at least 86% efficient.

Boiler position building regulations
Another important thing to consider is where you’ll position your boiler. In fact, there are boiler position building regulations that must be adhered to. Most people choose to hide their boiler in a cupboard or a spare room but this isn’t essential.
Some of the most common boiler locations are:
- Spare bedroom
- Airing cupboard
There are a few boiler position building regulations that apply when deciding where to place your boiler. Firstly, there needs to be sufficient space for an engineer to access the boiler. In addition, the wall where your boiler is fitted needs to be strong enough to support its weight. Finally, you need to ensure if your boiler is in a less well-heated area of your home that it has frost protection too.
Oil fired boiler installation regulations
When fitting a new or replacement oil fired boiler, your engineer will need to follow a range of guidelines.
Approved Document J sets out certain requirements regarding where you can safely position an oil storage tank. In order to comply with this, it may mean that the positioning of the new replacement tank will be different from the original tank site.
If the tank is to be positioned above ground the following points need to be met:
- Tanks need to be installed outdoors.
- They should be sited in a location that is separate from any surrounding buildings and their boundaries or anything that is likely to pose an ignition risk (in the event of a leak this will allow gas to safely escape into the air).
- If a fire is caused then the tank must be sited away from any other properties or outbuildings to ensure a fire doesn’t spread.
- Any potential entrances into a building that fall between the tank and the building such as drains or basement hatches should be sealed in such a way that gas cannot enter.
- Any fire wall should be constructed from concrete or solid masonry and should be fire resistant for a minimum of 30 minutes. If the fire wall forms part of the property then it should give at least 60 minutes of fire resistance.
Another oil-fired boiler installation regulation is that the boiler must be fitted by a tradesperson registered under a Competent Person Scheme. You’ll also need to check that the boiler is at a minimum 85% efficient. Finally, your oil boiler installer will need to ensure your new boiler meets Building Regulations approval.
Boiler flue position building regulations
Flues are an essential part of your boiler. They’re comprised of a pipe where gas can safely exit the boiler. One of the gases that needs to escape your boiler safely is carbon monoxide which can be deadly. The flue will guide these gases outside the home, keeping your tenants safe while using your boiler.
Your boiler fitter will need to follow boiler flue position building regulations at all times. These include ensuring that your flue is located far enough away from any windows and doors. 30cm is the minimum distance allowed but larger boilers may need to be positioned up to 60cm away.
Another boiler flue position building reg is to check that your flue is placed away from balconies, flat roofs and even the corners of buildings. Again, 60cm is the minimum distance allowed. Finally, if your boiler flue guides gas out onto a public walkway, it’ll need to be at least 2.1m above ground level.

You just need to get your boiler installed by a Gas Safe registered engineer who will then ensure your local authority is notified.
