Annual CP12 gas safety inspections carried out by Gas Safe registered engineers across all North London postcodes. We work with private landlords, letting agents and property management companies — certificates issued on the same day as the inspection.
The Gas Safety (Installation and Use) Regulations 1998 require all private landlords to have a Gas Safety Record — commonly called a CP12 — carried out annually on every gas appliance in their rental property. This isn't optional, it isn't conditional on the property's age, and it applies to every rental property in North London from a one-bedroom flat in Holloway to a large HMO in Tottenham. Failure to comply can result in unlimited fines, six months imprisonment, and — most seriously — genuine danger to tenants.
N4 Gas carries out CP12 inspections for landlords and letting agents across all North London postcodes. We understand the demands on landlords with multiple properties and work flexibly to minimise disruption. Our engineers are DBS checked, fully Gas Safe registered, and will deal directly with your tenants — giving them clear explanations and leaving the property exactly as they found it.
If a North London landlord cannot produce a valid, in-date Gas Safety Record, they can face prosecution, an unlimited fine and up to six months in prison. Beyond the legal penalties, in the event of a gas-related incident at a property without a valid CP12, landlord liability is essentially unlimited. No managing agent or letting agency in North London will manage a property without one — and most mortgage lenders and insurers require annual gas safety certification as a condition of cover. There is no acceptable reason not to have one.
Our Gas Safe registered engineers inspect all gas appliances at the property — typically the boiler, any gas fires, hobs and other appliances. For each appliance, we assess:
From a single buy-to-let flat in Islington to a portfolio of properties across Haringey — we handle CP12s for individual landlords efficiently and without fuss.
We work with many North London letting agents on managed portfolio programmes — coordinating directly with tenants, providing digital certificates and renewal reminders.
We're SafeContractor approved and work with housing associations and social housing providers across North London requiring compliant annual gas safety programmes.
Houses of multiple occupation across North London present specific compliance challenges. We're experienced in HMO gas safety inspections and understand the requirements.
We can accept key access for North London properties where tenants are not available, arrange appointments directly with your tenants, and provide them with an explanation of the inspection and a copy of the certificate where required. We understand that coordinating access across a portfolio of North London properties takes time — we make this as easy as possible.
Call or email with your property address and a contact for access. We'll confirm a date and time convenient for you or your tenant.
Our Gas Safe registered, DBS checked engineer carries out the full inspection of all gas appliances at the property.
On completion, the Gas Safety Record (CP12) is issued to you directly — by email or post, whichever you prefer. Tenants receive their copy as required by law.
We'll remind you when your CP12 is due for renewal — 4–6 weeks before expiry — so you never miss a deadline. No charge, no obligation.
