Do I need a CP12 as a landlord in Hertfordshire or London?
Yes. If you let a property with any gas appliance, flue or pipework, the law requires an annual Landlord Gas Safety Record — the CP12 — carried out by a Gas Safe registered engineer. You must give tenants a copy within 28 days of the check (or before they move in), and keep records for two years. There's no exemption for 'good condition' appliances, and the fines for missing it are far larger than the certificate costs.
What the check covers
Every gas appliance you supply: tightness, operating pressure, ventilation, flue flow, safety devices, and evidence of unsafe operation. Appliances the tenant owns aren't yours to certify — but the pipework serving them is.
The renewal window worth knowing
You can renew a CP12 up to two months before its expiry and keep the original renewal date — so there's no reason to run it to the wire. We track expiry dates across your properties and book the renewals before you'd have thought to chase them.
Portfolios
One number for every property: checks scheduled, certificates delivered digitally, reminders before each renewal, and a tidy audit trail if anyone ever asks. That's the whole point — compliance that runs itself.
