Slab over gas pipe

[sirgaz]

Hi everyone, I may have caused myself a bit of a dilemma ? Ok, so I decided to build a small timber frame extension on the side of the house for a toilet with a macerator as this is the best waste option. 50mm of darbo, then membrane, 140mm concrete with rebar, then 100mm kingspan, membrane again and 18mm floating caber board floor. All as it should be and working well, until I realised that the gas metre which was outside, is now inside. That in itself doesnt bother me but I since found out it might be against regs ?? What bothers me more and keeps me awake, is the fact that I have laid a slab over a gas service pipe which isn't against regs but I'm getting the skitters about the slab fracturing or pulling the pipe away from the metre if it moved or sunk a touch over time ? The slab is 2000mm x 900mm.
Whats your honest take on this as, am I worrying too much ?
Thanks in anticipation for your help ?

See pics and gas metre when slab was poured, and after where build is almost complete.

You should have involved Building Control for that. If you did, what do they think? If you didn't, you really should have.

Yes Denso, I am aware of that. I know I don't need planning but you are correct. I can get the gas line and metre re-routed, ( £850 ) I was quoted. Until that happens, can I sleep ! Lol

Leaving aside the above.
How do you find using that mini combined system?

The work should have involved B Control, however the gas meter and supply pipe are not covered by B Regs.

I like the basin, it's one where grey water is used in cistern for WC I gather. No excuse for not reading the meter in the future ).
