Can gas pipes be run under the floor?

[Urchin]

Hello

We are having our kitchen extended by basically adding a 3x4 room onto the side of our existing kitchen. We will be relocating the oven from the exisiting left hand wall to the far right wall of the new extension.
The layout of the rooms leaves few options with running the gas across. The only thing I can think of is running it under the floor.
Are you allowed to do this? We are also hoping to have underfloor heating, can you get both?

Obviously we will be getting a corgi registered person to do it but I just wanted to look at our options before getting someone in for a quote.

Thanks

Gas pipes can be installed under floors just make sure there's adequate protection, you want a minimum of 25mm screed over the top, so 25mm plus pipe diameter will give the chase depth and it has to have a protective coating.

It must take the shortest route and have no joints under the floor.

Thanks for your reply.

I have since heard you can also take gas pipes up over the ceiling?
Is that true and should it cost a lot to have that done?


Thanks :)

You can run gas pipes in most situations, but you need an RGI to do it, they will know or be able to check regulations and distances between gas pipes and other services.

The cost - depends on who you get bascially.
