Liquid Gas UK re-launches Code of Practice 1 part 4 with new guidance for below ground installation of LPG Tanks.

Monday 12th April 2021

Liquid Gas UK has recently re-launched Code of practice 1 Part 4 – Bulk LPG Storage at Fixed Installations: Buried/Mounded LPG Storage Vessels.

Code of Practice 1 part 4 was first launched back in 2008, and has recently been updated to reflect developments in installing and positioning LPG tanks below ground.

Code of practice 1 part 4 is of particular relevance to large country homes and estates, mobile home parks and caravan sites.

From a visual and space saving perspective burying the LPG storage vessel is often a preferred method of installation. This code of practice details a safe process as well as key installation techniques for burying an LPG tank below ground level.

Richard Hakeem Director of Safety and Technical Policy at Liquid Gas UK commented:

“We know that installing below ground level is often preferred for both aesthetic and space saving purposes. Code of Practice 1 Part 4 explains the safety guidelines to follow when burying LPG vessels below ground.

We’ve worked closely with the Health and Safety Executive to produce this update due to the strict regulations which must be adhered to.

We’ve also consulted with experts in below ground installation as there are various considerations to take into account when installing in this way including cathodic protection, and excavation techniques to ensure the tank is securely positioned.”

Code of Practice 1 Part 4 is now available to download from Liquid Gas UK. To purchase please visit
