Gas and Electrical Certificates for Caravan Engineers: What You Need and How to Show It

To work legally and safely on caravan habitation systems in the UK, gas work on a caravan's LPG installation must be carried out by a Gas Safe registered engineer who holds the correct leisure accommodation vehicle (LAV) LPG competence — usually the CONGLP1 LAV category — not the standard domestic natural-gas qualifications. Electrical work has no Part P requirement because a caravan is not a dwelling, but the installation must comply with BS 7671 Section 721, and you should be competent to inspect, test and issue certification against that standard. Below we explain each qualification, where it comes from, and how to display it so owners choose you.

What LPG gas qualification do caravan engineers need?

A touring caravan or motorhome runs on LPG (propane or butane), not mains natural gas, and the appliances, pipework and cylinder arrangement sit inside a leisure accommodation vehicle. That means domestic gas categories on their own do not cover you. The relevant competence route is the LPG leisure accommodation vehicle category — commonly recorded as CONGLP1 LAV — which covers LPG in caravans, motorhomes and similar vehicles, alongside appliance-specific competences such as cookers, space heaters and water heaters where you work on them.

By law, anyone carrying out gas work as a business must be on the Gas Safe Register for the specific work they do. Your registration card lists the categories you hold, so an owner (or a park operator) can check exactly what you are qualified for. You can confirm what each category means and check registration status at gassaferegister.co.uk. The legal duty behind this sits in the Gas Safety (Installation and Use) Regulations — see gov.uk for the underlying rules.

In short: holding a domestic Gas Safe registration does not automatically let you touch a caravan's LPG system. You need the LAV LPG categories added to your registration. If you plan to work on statics on holiday parks, check whether the site or manufacturer expects any additional appliance categories too.

What is CONGLP1 LAV and how do I get it?

CONGLP1 LAV is the core assessment covering LPG safety in leisure accommodation vehicles — the general gas competence for working on caravan and motorhome LPG systems. It is assessed through the ACS (Accredited Certification Scheme) route at an approved gas training centre, and you then add the appropriate appliance categories (for example water heaters, space heaters and cookers) depending on the work you do.

The typical path is:

• Training and assessment at an ACS-approved centre, either as new entry (via a recognised managed-learning route) or as an existing gas operative adding categories.
• Certificate issued on passing, valid for a set period (commonly five years) before reassessment.
• Gas Safe registration updated so the LAV categories appear on your card and public record.

Because requirements and category codes are periodically updated, always confirm the current, correct qualification set with your assessment centre and with the Gas Safe Register before you book. Never assume an old certificate still covers the work you are quoting for.

Do caravans need Part P for electrical work?

No. Part P of the Building Regulations applies to fixed electrical installations in dwellings in England and Wales. A caravan is not a dwelling, so Part P notification does not apply to work on the caravan's own installation. That does not mean electrical work is unregulated — the recognised standard for the electrical installation in a caravan or motor caravan is BS 7671 Section 721 (the IET Wiring Regulations).

Section 721 sets out the specific requirements for caravans and motor caravans: things like the inlet connection, RCD protection, flexible cabling suited to movement and vibration, extra-low-voltage circuits, and the notice that must be fitted advising the user on connecting and disconnecting supply. Separately, Section 708 covers the electrical installations of caravan parks and pitches, which matters if you also work on the supply side on sites. You can read about the standard and buy the current edition of BS 7671 via the IET at theiet.org.

The practical takeaway: to inspect, test and certify caravan electrics properly you need to be genuinely competent in BS 7671 and its caravan-specific requirements — not just confident with a socket in a house.

What is a caravan EICR and when should you issue one?

An EICR (Electrical Installation Condition Report) records the condition of an existing electrical installation against BS 7671, listing any observations and coding defects for remedial action. For caravans, the inspection and testing are carried out against the Section 721 requirements, so a caravan EICR reflects the movable, plugged-in nature of the installation rather than a fixed house circuit.

Owners commonly want a caravan EICR:

• Before buying or selling a used caravan.
• As a periodic check after several years of use, damp, or towing vibration.
• After alterations, additions or a suspected fault.
• Where a holiday park or insurer asks for evidence of a safe installation.

Issue the report only for work within your competence, use appropriate test instruments, and record findings honestly with correct classification codes. New work or alterations should instead be certified with the relevant installation certificate. If you are unsure which document applies, the guidance published by scheme operators and the IET is the right reference point.

Do I need to join NICEIC or NAPIT?

You are not legally obliged to belong to a competent-person scheme to do electrical work on caravans, precisely because Part P self-certification does not apply here. However, registering with a recognised scheme such as NICEIC or NAPIT has real value: it provides independent assessment of your competence, ongoing technical support, standard certification documentation, and a credential that owners and parks recognise.

Scheme membership is a strong trust signal, but be accurate about what it means. Describe your registration factually — for example "NAPIT registered" or "NICEIC certified" — and never imply an endorsement or approval you do not hold. The same honesty applies to your Gas Safe status: state your registration number and the categories on your card, and let the customer verify it on the public register.

How do I show my certificates to customers?

Owners increasingly ask to see proof before they let anyone near their van's gas or electrics — and rightly so. Make it easy for them:

• Show your Gas Safe card and number so customers can check your LAV categories on the register themselves.
• Reference your BS 7671 competence and any scheme registration (NICEIC / NAPIT), with membership numbers where relevant.
• Keep certificates current and be ready to reassess before expiry — an out-of-date card costs you jobs.
• Give clean documentation — a properly completed EICR or installation certificate looks professional and protects you.
