Who Can Issue an Electrical Safety Certificate for My Catering Trailer?
Zoe from Ramsgate was ringing round for an electrical certificate for her trailer and couldn't find anyone willing to take the job.
She wasn't doing anything wrong. A catering trailer counts as a mobile unit under Section 717 of the wiring regulations, and not every domestic electrician works with that, so they shy away. What you're after is an EICR, renewed yearly if you run off a hook-up lead. When you phone round, ask straight out whether they've tested caravans, motorhomes or exhibition stands, and use the free postcode search on the NICEIC and NAPIT sites. Caravan and marine electricians are often your best local bet.
