-
What is a CP12 gas safety certificate?
CP12 is the everyday name for a landlord gas safety record: an annual Gas Safe check of appliances, flues and pipework.
-
How long does a gas safety certificate last?
A landlord gas safety record is valid for 12 months. HSE also allows a two-month early-renewal window that can keep the original deadline.
-
Who needs a gas safety certificate in England?
Private landlords with gas appliances need an annual Gas Safe inspection. Homeowners selling, and some commercial operators, often need a current record too.
-
Landlord certificates London landlords typically need
The usual Greater London private-let pack is a CP12, an EICR, an EPC, and working smoke and carbon monoxide alarms. HMOs may need more.
-
What is an EICR electrical safety certificate?
An EICR inspects the fixed electrical installation, records C1–C3 and FI codes, and states whether the installation is satisfactory.
-
EICR codes C1, C2, C3 and FI explained
England’s PRS guidance: C1 danger present, C2 potentially dangerous, C3 improvement recommended, FI further investigation without delay.
-
How often do landlords need an EICR?
The England private rented sector duty is at least every five years, or the earlier date printed on the last report, with a copy for tenants.
-
What is an EPC Energy Performance Certificate?
An Energy Performance Certificate rates a building from A to G. You must have one before marketing a sale or let in England, with listed exceptions.
-
How long does an EPC last in England?
GOV.UK: an EPC lasts 10 years and can be reused for sale or let until it expires or a newer certificate replaces it.
-
Is PAT testing a legal requirement?
Portable appliance testing is not a statutory annual certificate. HSE requires maintenance that prevents danger; frequency is risk-based.
-
What is a CP42 catering gas certificate?
CP42 is used on this site for catering and commercial kitchen gas certification — distinct from a domestic landlord CP12.
-
Do LPG catering trailers need a certificate?
LPG is not a mains-gas CP12. Homes, commercial sites and mobile catering that use cylinders or tanks need a competent LPG safety check.
-
Commercial gas safety certificate for London businesses
A commercial gas safety certificate is for non-domestic premises. It is not a residential CP12. Published Greater London prices start at £149.
-
Fire alarm certificate for London landlords
A fire alarm certificate records inspection of the alarm system. Typical extra for HMO or commercial stock, not a substitute for smoke alarms in a single let.
-
Emergency lighting certificate for commercial property
Emergency lighting certificates record inspection of escape lighting. They sit with fire alarm checks on many HMO and commercial sites.
-
Gas certificate vs boiler service: the difference
The CP12 records that appliances, flues and pipework were checked. A service follows the manufacturer’s maintenance instructions. They are not the same.
-
Smoke and carbon monoxide alarms for landlords
From 1 October 2022, England’s amended alarm regulations require storey smoke alarms, CO alarms by most combustion appliances, testing at new tenancies, and prompt repair.
-
EICR vs PAT testing: which certificate do you need?
Use an EICR for the installation. Use PAT for plug-in appliances. Landlords usually need the EICR; PAT is extra maintenance, not a replacement.
-
When do tenants get a gas safety record?
Existing tenants: within 28 days. New tenants: before move-in. Keep records at least two years. Greater London CP12 from £59.
