QUOTE FROM REGULATIONS.
All Gas systems including those in privately owned caravans and motorhomes are subject to the regulations contained in the UK Gas safety (Installation and Use) Regulations, which in essence require all gas installation, services,/maintenance repair and removal of gas appliances to conducted according to the regulations.
The regulations make special provisions for touring caravans, in so far as they do not require the fitter to be CORGI registered, BUT under:
Statutory Instruments 1998 No. 2451
The Gas Safety (Installation and Use) regulations 1998
"Part B - General Provisions
Section 3- Qualification and supervision. -
(1) No person shall carry out any work in relation to a gas fitting or gas storage vessel unless he is competent to do so."
and
"(4) The requirements of paragraph (3) above shall not apply in respect of -
(a) the replacement of a hose or regulator on a portable or mobile space heater; or
(b) the replacement of a hose connecting a re-fillable cylinder to installation pipework."
These regulations are not superseded by any further subsections.
Failure to do so is a breach of the Health & Safety regulations that view such breaches as a criminal act, and in the event of an incident that is prosecuted the guilty person might receive a prison sentence.
If you have gas work carried out on your caravan that is not compliant to the regulations your insurance company may have cause to avoid liability in the event of any claim.
