Bundled tank or not

The folks have to get a replacement oil tank, legally does it need to be bunded in this setting?
They live in a city residential area, the old tank is about 1 meter from the rear of the house, there are drains related to downpipes close enough too.
Thanks

Here is some info and places to find more.

Thanks, also the new oil burner is situated outside, I’d say approximately 2m from the existing tank, from the info I’ve given do you think it should be bunded, at a guess I’d say yes?

The bund is to protect the environment from leakage contamination. It offers no real fire protection.

So what kind of tank would you buy if you were in their situation, single skin or bunded?
Thanks

Nowadays I always recommend bunded in every instance.

At 2 metres, you might be far enough away from the boiler (flue). I don't have the most up-to-date regs to hand, but you should be able to find what you need on the oftech site or part J of building regs.

BTW Read what I sent regarding how close it can be to the house. The house wall AFAIK is considered fire rated if it doesn't have an opening.

pages 47 48 and 49 of above it part J of building regulations that apply to oil storage not part L

Nowadays, the only place you’d realistically get away with a single skin tank is in the middle of a large field, to comply with all clearances. Always fit a bunded tank. I’d always make note in the boiler passport too that a bunded tank should be fitted because almost no current single wall tank that’s fitted in Ireland is up to current standards

How much is a bunded 1000L tank ?
I need a new one this year.

Can you not build your own bund for the tank to sit in?
A bund is just a secondary containment - doesn't have to be sealed on top as long as it stops oil from leaking to environment.

The expense of that would be outweigh the cost of the tank.
A 1,000 l tank is around 800-900

The 4". The other one is usually used for remote filling.

i put in the 650 litre bunded tank myself , took me 5 hours including pumping 250 litres from old to new with a tiny drill powered pump
i also strapped the tank down as it gets very windy here if the tank was low it may move .

great peace of mind now its in ,and i can start ordering larger and cheaper deliverys .
