Got a portfolio in Brent? 10% off each.
Landlords with 3+ rental properties in HA0, HA9, HA1, HA3, NW9 or NW10 get a 10% discount on every CP12, every year. I keep your portfolio diary, send you a reminder 30 days before each one is due, and co-ordinate with tenants on your behalf so you don't have to.
The three things the Regulations require me to check.
A CP12 is not a five-minute box-tick. Under the Gas Safety (Installation and Use) Regulations 1998, three categories must be inspected on every appliance. A real engineer takes 30 minutes minimum, even on a one-bed flat.
// Every CP12 · same three categories
- Every gas appliance — make, model, serial number, location.
- Gas tightness — let-by and standing-pressure test at the meter.
- Operating pressure — manometer at each appliance test point.
- Combustion — flue gas analyser (CO ppm + CO/CO₂ ratio).
- Safety devices — flame supervision, overheat thermostat.
- Flue integrity — visual run, terminal, joints in loft if present.
- Ventilation — grilles checked for blockages.
- Spillage test — on any open-flued appliance.
- Gas pipework — visible runs, corrosion, accessibility of ECV.
- Digital LGSR emailed to landlord + tenant by evening.
Fines start at £6,000 per property.
A lapsed CP12 isn't just paperwork. It's a criminal offence under the Gas Safety Regulations, and in real terms the consequences land in three places.

Honest answers about CP12s.
How much is a CP12 in Wembley?+
£65 fixed for a single-appliance combi-only property in Wembley and the surrounding Brent area. £75 for two appliances (combi + hob), £85 for three (combi + hob + fire). Block bookings of 3+ properties receive 10% off per inspection.
What happens if my CP12 has expired?+
You are committing a criminal offence under the Gas Safety (Installation and Use) Regulations 1998. HSE fines start at ~£6,000 per property. Most landlord insurance policies also become void during any lapse — book a same-day inspection to limit your exposure.
How long does a CP12 inspection take?+
30–40 minutes for a one-bed flat with a combi only. 60–90 minutes for a three-bed house with multiple appliances. The certificate is emailed digitally by the same evening.
Do you offer same-day CP12?+
Yes, most days. Call before 11am and I can usually fit you in that afternoon. Same-day is no premium where I have capacity.
Do I need a CP12 for an electric-only property?+
No. The Gas Safety Regulations only apply where there is a gas appliance or gas pipework. If your rental is fully electric, a CP12 is not required.
Can my tenant refuse access?+
Tenants can delay but cannot indefinitely refuse access. Three written attempts in escalating tone over a 4-week window is the accepted standard. Keep paper copies.
Do you do service + CP12 in one visit?+
Yes — £120 fixed for combined annual service + CP12. Saves £20 vs separate visits and means one tenant visit instead of two.
