The best garden location for an oil tank is important to know.
Living in the rural UK countryside has its many charms; birdsong in the morning, beautiful rolling hills – and being unconnected to the national gas grid, of course! This last point means that in rural areas across the UK, heating oil tanks are a bit of a staple. Before you put one in your garden, however, it’s really important to know where it can legally and safely go.
Let’s discuss and take the stress out of oil tank placement.

Location matters
Your oil tank should be thought of like a house guest – it needs its own space, not too close to your house and you really don’t want it causing any mess! A poorly placed tank can be more than just inconvenient. Regulations are put in place for a reason, and one of the biggest reasons is that oil tanks can leak, harm your garden soil or even pose a fire risk.
Not only that, but when the time comes to refill or service your oil tank, you want it to be within easy reach. A gym session just to access it every time is far from ideal!
The must-know rules for installing an oil tank
There are some clear guidelines in the UK about how far away your oil tank needs to be from various things. Here’s a handy cheat sheet:
- At least 1.8 metres from sheds, fences or garden buildings that aren’t fire-rated
- At least 0.76 metres from brick walls or other non-combustible structures
- At least 1.8 metres from doors and windows
Alongside this, you’ll also want to keep a heating oil tank away from drains, ditches and streams. A leaky tank can cause serious environmental issues. Your oil tank should also have plenty of ventilation and stay well away from anything that could spark. If you don’t have enough space, you might need a fire-resistant barrier to keep everything safe and comply with the legal regulations.
It’s also important to note that if your tank holds more than 2,500 litres or is anywhere near water or drainage, then you’ll be legally required to have a bunded oil tank. A bunded oil tank has a second skin for extra protection.
Do you need planning permission?
It’s unlikely that you’ll need planning permission when installing a heating oil tank. The only exception to this is listed properties, those within a conservation area or if your property has any specific planning restrictions. In those cases, it’s always wise to check with your local planning authority first and foremost.
Mistakes to avoid
Avoid headaches down the line with these common no-gos!
- Don’t squish it up against a fence or under a window – clear space is super important
- Don’t place it on soft or uneven ground – a solid, level base is vital. Go for concrete or paving slabs to prevent the tank from shifting or tilting over time.
- Make it accessible with space to move around it to allow for maintenance visits.
Installing a heating oil tank might feel a bit complex but once you know the rules, it’s pretty straightforward. If you’re ever in doubt, the experts at OFTEC are your go-to for up-to-date advice and clear guidance.
