What is this pipe?

I also suspect it could be gas.  I've seen similar heavy duty with screw couplings in older industrial properties before colour coding came into play.  It could be a spur off the mains and serve a number of properties.

Just because the pipe is exposed now doesn't mean it always has been.  If mower drivers hit it now they may also have dislodged a cover.

Do your neighbours also have the same?

Nope none of the houses in my area have the same pipe,
 Thanks for the help everyone, do you think I should contact the gas-board regarding it? 

Thanks

It certainly looks like gas barrel. Perhaps your house had the gas supply installed after that wall was built. Instead of digging under the wall, they made a hole through it?

The snag with contacting the gas company is that they may want to replace the pipe, at your expense!

Arguably better than having a gas torch at the end of your drive (and likely a loss of gas to house)

It won't be at your expense; it's before the meter and presumably on the public highway.

Looks like it is Gas, I’ve emailed a photo to Cadent and they are sending an engineer out to assess it. 

Many thanks
