Formerly OC 440/34
This guidance replaces OC 440/34 v2 and provides information and advice to operational staff on the application of the Gas Safety (Installation and Use) Regulations 1998 (GSIUR) to leisure accommodation vehicles and residential park homes, and enforcement demarcation.
This guidance provides information on how and when GSIUR applies to caravans to assist with the decision on whether to investigate concerns, or incidents reported to HSE under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 (RIDDOR); also advice on enforcement allocation.
GSIUR apply in many cases and enforcement responsibility may fall to HSE or Local Authorities, depending on the use and location of the caravan .
An incident (fatality or serious injury) reportable under RIDDOR does not necessarily attract duties under gas safety legislation e.g. where a dutyholder is not implicated.
For the purpose of this guidance, unless otherwise specified the term ‘caravan’ will be used throughout – definitions are set out below.
When making a decision whether to investigate a concern or incident involving a ‘caravan’, the following should be taken into account:
In making this decision, it will be helpful to refer to The Approved Code of Practice and Guidance Safety in the installation and use of gas systems and gas appliances (L56, fourth edition)
Where the circumstances are unclear, there should be liaison with the relevant Local Authority (LA) and consideration of joint investigation if there are shared responsibilities e.g. on a residential site.
Inspectors coming across incidents which have not been reported under RIDDOR, may need to prompt the responsible person (whoever that might be in the circumstances) to submit an incident report.
Application of the Gas Safety (Installation & Use) Regulations 1998 (GSIUR)
GSIUR and L56 include the following specific references to caravans:
GSIUR does not cover the majority of portable appliances but, where mobile space or cabinet heaters are used in caravans, they are subject to the provisions of regulations 3, 35 and 36. However, as British Standards for the installation of space heating in leisure accommodation vehicles (LAVs) and residential park homes (RPHs) do not include portable appliances they should not normally be found.
In the event of a landlord or engineer supplying a portable heating appliance while, for example, the fixed heating system is being repaired, they may be in breach of HSWA Section 3 or consumer safety legislation if the appliance can be shown to be unsuitable for the purpose used. Trading Standards Officers should be consulted on consumer safety issues.
Make it clear in COIN reports that the issue concerns gas safety in a caravan, to include the type of gas and vehicle

The term caravan covers tourers, motor-caravans and caravan holiday-homes, collectively known as leisure accommodation vehicles, (LAV) and residential park-homes (RPH). They are described in more detail in the following paragraphs together with the current applicable standards for construction and gas safety. Note: as standards are regularly updated, always check with British Standards on-line for the standard in force at the time the caravan was built or upgraded.
Tourers are those seen on the road being towed by cars. They are built to BS EN 1645 and must meet the requirements for the construction and use of road vehicles.
Motor-caravans incorporate the living accommodation similar to that of a touring caravan on to a motor base vehicle and are therefore designed specifically for touring. They are built to BS EN 1646 and must meet the requirements for the construction and use of road vehicles.
Caravan holiday-homes are designed specifically for holiday accommodation on licensed caravan holiday parks. Because of their size and weight they are delivered to the park by transporters. They are manufactured with wheels solely to manoeuvre them on site. They are built to BS EN 1647, LPG systems are covered by BS EN 1949 and safety ventilation requirements by BS EN 721.
Park-homes are designed for permanent residential accommodation. They are still caravans, even though they have pitched tiled roofs and may appear similar to a brick built bungalow. Because of their size and weight they can only be delivered by transporters, sometimes in two halves which are then bolted and secured together when in situ. They are built to BS 3632 which covers ventilation.
The LPG installation is covered by BS 5482-1 and BS 5440-1 and the flues and terminals by BS 715 (partially replaced by BS EN 1856-1:2003 & BS EN 1856-2: 2004).
Natural gas installations are covered by BS 6891 and BS 5440-1 and the flues and terminals by BS 715 (partially replaced by BS EN 1856-1:2003 & BS EN 1856-2:2004).
The majority of appliances found in caravans will be fuelled by LPG; the generic name for commercial butane and commercial propane.
Butane is not suitable for installations subject to low external temperatures and is therefore mainly used for tourers and motor-caravans. There is no standardised colour for butane cylinders; blue, yellow/ochre, and white are common.
Propane is ideal for outside storage and therefore used to supply residential park-homes and caravan holiday-homes. Although often supplied in red cylinders it may also be supplied in cylinders of orange or other less common colours. Patio gas propane, an increasing market, is supplied in green cylinders. Bulk storage vessels at the customer's (e.g. caravan park operator) premises are normally coloured white or green.
In some caravan sites natural gas is supplied from a gas conveyor's local distribution network. Often there is a bulk supply meter at the site boundary from which the gas is then conveyed around the site in pipes to each caravan. The pipes on the site could be owned by the gas conveyor or by the park operator.
In certain circumstances, the pipes on the site may be part of a network as defined in the Gas Safety (Management) Regulations 1996 (GSMR) and subject to GSMR, including safety case requirements. Guidance on GSMR is contained in A guide to the Gas Safety (Management) Regulations 1996 - L80.
The end of the network is at the first emergency control valve (ECV) (as defined by GSIUR) and defines the cut-off point between GSMR and GSIUR. If the pipes are on the network and owned by the upstream gas conveyor, then they should be covered by their safety case. If the park operator owns the pipes then they may be required to produce a GSMR safety case.
OC 440/28 provides further guidance on the liaison between HID and FOD on gas safety matters. HID is responsible for GSMR safety case matters.
