To help you get started, here’s some information about testing carbon monoxide detectors…
Did you know that gas appliances like boilers, heaters, and cookers need regular check-ups to keep them safe? If they’re not looked after properly, they can stop working well and might even produce a dangerous gas called CO. That’s why it’s super important to remind the grown-ups in your family to have these appliances serviced by a Gas Safe registered engineer every year. Servicing keeps everything running smoothly and helps keep your home safe and warm. You can even help by putting a big star on the calendar when it’s time for the next check-up. A little reminder can make a big difference!
You can discover more about CO with Safety Seymour here and with the CO Crew here.
Remember, safety starts with YOU! Submit your 30 second advert and help keep homes safe.

If you’re the winner, you’ll get a £100 voucher and your advert will be played on Fun Kids!
And at the end of the year, we’ll pick an ULTIMATE WINNER… who will win another £100 voucher.
If you win, you can select a voucher from LEGO, Smyths Toys, The Entertainer, Nintendo and PlayStation.
Competition closes midday on Saturday 28th February, 2026.
