Can anyone recommend: Bottled Gas hob installer

Hi have a property on Los Olivos and I am looking to change my electric hob for a bottled gas type.

Have found the hob but need a qualified and certified gas engineer that is capable of undertaking the work.

They would need to run a pipe from the utility room adjacent to the kitchen and then certify the works as being installed to code.

Appreciate any help with this as I don’t seem to be able to find anyone.

Many thanks in advance
