Yeah it should be around 15 inches deep.

There used to be a fixed depth but they now try and get out of it by saying they are only advisory. Push it with them as the minimum used to be 18 inches they usually give up and do it for nothing

If it's on your land & there's nothing in the deeds stating that the gas company have the right to be there then they're trespassing, I think the term is "easement". Another thing is on new type estates where the garden comes right out to the kerb, the first 1m is the service strip where you will find every utility, if you are in that situation then your stuffed, incidently you should be covered for this on your bricks & mortar insurance.
From what I can remember from when I worked for the water board gas mains should be around 2 foot deep at least & marked by yellow identifying tape, if you want to find out the proper depths that utilities should stick to you need to refer to the Public Utilities Street Works Act1950 otherwise known as PUSWA.

Just found this on the HSE site;

Minimum depth requirements
Gas mains and service pipes should be designed and installed in accordance with the requirements of the Pipelines Safety Regulations 1996 (PSR). PSR does not specify how deep mains and services should be laid.

However, the Regulations are supported by HSE guidance 'A guide to the Pipelines Safety Regulations 1996' and there is also a Health & Safety Commission [HSC] Approved Code of Practice and Guidance 'Design, construction and installation of gas service pipes'.

These publications refer to the Institution of Gas Engineers' guidance 'IGE/TD/3 Distribution Mains' and 'IGE/TD/4: Gas services' which specify the minimum depth of cover which gas mains and services should be laid in order to minimise the risk of accidental third party damage.

HSE expects mains and services to be laid at the depths specified in these publications unless other effective precautions are taken to minimise the risk of third party damage.

A gas main should normally be laid with a minimum depth of cover of 750 mm in a road or verge and 600 mm in a footpath.
A gas service pipe should normally be laid with a minimum depth of cover of 375 mm in private ground and 450 mm in footpaths and highways.
However, these depths are only a guide and should not be relied on when carrying out work near gas services or mains. For example, road levelling, landscaping and other changes to ground conditions after a gas main or service has been laid (often decades before) can result in the depth of the ground cover changing over time. Also, gas pipes may have projections coming from them, such as valves, which are not shown on plans and may have less depth of cover than the pipe.


Although yours is in a garden you need to quote the figures for a gas main not a service as that pipe is a 63mm main which is probably feeding the whole street.
Hope this will get them off your case.
