Willerby has handed more than 1,300 smoke alarms to Humberside Fire and Rescue Service. Good for Hull. Good for the people who will get one fitted free.

But the donation isn’t the trade story. The reason Willerby had 1,300 alarms it couldn’t use is.

They’re battery-powered. Holiday homes from NCC member manufacturers have to carry mains-powered alarms instead. If you sell, site or let holiday homes, that difference sits inside every unit on your park.

What Willerby Has Actually Done

Strip away the community angle and the facts are simple:

  • Willerby had a surplus of more than 1,300 battery smoke alarms it could no longer fit to its holiday homes.
  • The company says they still have over eight years of battery life left.
  • Humberside Fire and Rescue Service will fit them free during Home Fire Safety Visits to vulnerable residents.
  • Some will go to households supported by Women’s Aid.

Let’s be fair. Plenty of businesses would have binned that stock. Willerby found it a second life where it can save lives, and it fits the waste-reduction story the company has told in its sustainability reporting.

It’s also a tidy piece of community work in Willerby’s 80th anniversary year. That’s fine. The interesting part is what it tells you about the stock already out there.

The Rule Most Buyers Have Never Heard Of

The release calls the NCC rule “new guidance”. It isn’t that new.

The NCC’s Guidance Note 17, written with the Fire Industry Association, covers holiday caravans and park homes made from 1 September 2022. It is mandatory for NCC member manufacturers and recommended for everyone else.

It asks for:

  • Mains-powered smoke and heat detectors, each with a tamper-proof battery backup (Grade D1)
  • Interlinked detectors wherever there’s more than one
  • A smoke detector in the hallway, within 3m of bedroom doors
  • A heat detector in the kitchen
  • A smoke detector in the lounge, unless it’s open-plan to a kitchen covered by the heat detector

In plain terms: one alarm sounds, they all sound, and the backup battery is tamper-proof.

Why This Matters Beyond Hull

Holiday homes built before September 2022 were built to an older standard. Willerby’s surplus shows battery alarms were standard kit until the rule changed.

Those units haven’t gone anywhere. They’re sold on, resited and let out every week.

The NCC note draws a clear line. Holiday homes used for holiday letting fall within fire safety legislation. Homes owned for private use are treated as private premises and sit outside it.

So the same 2019 holiday home can carry very different duties depending on who uses it. Owned and used by a family: their call. Let out through the park’s hire fleet or an owner’s sublet: a fire risk assessment applies, and that assessment may call for more than the minimum.

The note also warns that upgrading the alarm system in a factory-built caravan isn’t always possible. That matters when a buyer picks an older unit planning to let it.

The timing is pointed. On 1 October 2026, the FIA published new holiday caravan fire safety guidance prepared for the Resort Leisure Safety Group.

It covers fire risk assessments, fitting and maintaining smoke alarms, and briefing guests. Fire safety on parks is getting more attention, not less.

What This Means for Park Operators and Holiday Home Sales Teams

Holiday homes are sold mainly through holiday parks and holiday home dealers, not the touring network. That’s who needs to act.

  1. Know what’s in your stock. For every pre-owned unit on sale, check the build date and the alarm type. Mains-powered and interlinked, or battery? Put it on the spec sheet.
  2. Ask the letting question at the point of sale. If the buyer plans to sublet, they need to know the fire safety duties that come with it, and whether the unit’s alarms can be upgraded.
  3. Audit your hire fleet. Any older unit you let yourself sits within fire safety legislation. Check your fire risk assessments are current and match the alarms actually fitted.
  4. Use the RLSG guidance. It includes example layouts, a risk assessment template and inspection checklists. That’s ready-made training for your team.
  5. Check your parts stock. Battery alarms can’t go into new NCC-compliant units. Willerby’s answer was the local fire service. Yours could be the same.

Here’s the blunt truth: “it’s got a smoke alarm” is no longer a complete answer when a buyer asks about safety.

What This Means for Holiday Home Owners

If your holiday home was built from September 2022 by an NCC member, it should have mains-powered, interlinked alarms with battery backup.

If it’s older, check what you’ve got. Test the alarms. Look for the replace-by date printed on each one.

And if you let your holiday home out, even for a few weeks a year, you’re no longer just an owner. Ask your park which fire risk assessment covers your unit.

The Bigger Signal

Willerby’s donation is a good-news story, and it deserves the credit.

But the lesson for the trade is the reason behind it. The standard for new holiday homes moved four years ago. The older stock on your park didn’t move with it, and the gap lands on whoever sells, sites or lets those units.

If a buyer asked you today what alarm system is fitted in every pre-owned unit on your sales pitch, could you answer?
