New to gas safety certificate in Holywood?
First gas safety certificate for your Holywood let? Here’s what the visit involves, what to have ready, and how often the law expects it — in plain English, with links to check.
A gas safety certificate (often called a CP12 or landlord gas safety record) is the paperwork from a Gas Safe registered engineer confirming the gas appliances, fittings and flues you provide have had their annual safety check. Think of it as the yearly MOT for the gas in your let — short visit, important record.
What’s involved
Aligns with hub `#guide` teaser; expands visit/prep detail for town pages.
- A Gas Safe registered engineer checks each gas appliance you provide (boiler, hob, fire, water heater) plus relevant flues, ventilation and pipework for safety.
- They look for gas tightness, correct operation, and anything that could cause carbon monoxide or other danger.
- You get a landlord gas safety record (the certificate). One record usually covers all appliances checked that day.
- The engineer should only issue the record once the checks are done. If something’s unsafe, they may disconnect or warn “Danger Do Not Use” — you then arrange remedial work. Keep notes of follow-up work alongside the record.
- LPG counts too. Off the gas grid with bottled or tank LPG? The yearly check still applies if you provide those appliances — book someone who covers LPG.
How long a typical visit takes
Times vary with how many appliances you have and how easy access is. Honest ranges, not guarantees:
- Often 30–60 minutes for a typical flat or small house with one boiler and a hob.
- Allow 45–90 minutes if there’s a gas fire, secondary heater, awkward cupboard, or LPG setup.
- Larger HMOs or multiple boilers take longer — ask when you book.
- Add buffer for parking, meter location, and tenant handover. Same-day digital copies are common; ask how you’ll receive the certificate.
What the landlord must have ready
- Access arranged with the tenant (or vacant possession). Put access rights in the tenancy agreement; don’t force entry.
- Clear path to the boiler, gas meter, cooker and any gas fire — cupboards emptied enough to work safely.
- Appliances switched on and usable (or tell the engineer if something’s isolated).
- Previous gas safety certificate / record if you have one (helps continuity).
- Landlord or agent name and address for the record (you don’t have to sign it, but details must appear).
- Working carbon monoxide alarm where rules require one (nation rules differ — see below).
- If off-grid: note whether it’s LPG so the right engineer is booked.
Tips to prepare
- Book early. You can usually have the check up to two months before the anniversary and keep the original deadline — useful for diary planning. Confirm current HSE guidance when you book.
- Tell tenants in writing the date and why it matters. If access fails, keep a paper trail of attempts (notes through the door, emails, offered rebooks).
- Check CO alarms work before the visit — better than finding a flat battery on the day.
- Don’t block vents or flues; clear laundry and storage from boiler cupboards.
- Between tenancies, confirm appliances left behind, open-ended pipes, or vandalism — HSE advises a fresh check before re-letting if anything looks tampered with.
- Keep records at least two years (longer if you use the early-check flexibility — see HSE). Electronic copies are fine if secure and printable.
