THE RISK IS REAL. THE CHECK IS £95.
Faulty gas appliances kill people. Carbon monoxide is colourless, odourless, and undetectable without an alarm. The Gas Safe Register, which runs the UK's regulation of gas engineers on behalf of the HSE, found that one in every five UK homes contains a potentially dangerous gas appliance.
The annual CP12 is the only legal way to know yours is not one of them. HSE fines for renting without one start at £6,000 and have no upper limit. The penalty for skipping it is unbounded; the cost of doing it is fixed.
Every box ticked, every visit.
A Gas Safety Certificate is not a quick look. Our Gas Safe registered engineers spend 45 to 60 minutes inspecting every gas appliance, every meter, every flue and every connection in the property. The CP12 we issue is the document your tenancy depends on, and the document you would produce in an HSE inspection.
Adding the boiler service means the engineer also runs a full annual service while they are with you. The boiler gets a combustion check, a pressure test, an internal component inspection, and a written service record. Most boiler warranties require an annual service to remain valid, and most insurers expect one too. Done as a pair, it is £138 for both, against £154 to £185 if you book them separately later.
We email the digital certificate the same day. Hard copy is available on request at no extra cost. Documents are stored in your Hello Neighbour account for the lifetime of the property.
James · Trustpilot review"Hello Neighbour went above and beyond my expectations regarding renting out my London property!
They are not only super transparent on their fees - so there are no complicated calculations to make but they also helped me with electrical and gas certificates, finding cleaners etc... every time I had a question they had a solution. Super helpful and super friendly!"
Stop doing this
every year.
Most landlords run their own compliance and book certificates as they expire. Some would rather hand the whole property over and never think about it. Both are fine. Here is what each looks like.
Book certs as
they expire.
If you stay on the DIY path, these are the certificates you will need, in cadence and cost. We send reminders 60 days before each one expires.

QUESTIONS ON GAS SAFETY.
Not finding what you need? Talk to the team, or check engineer credentials yourself on the Gas Safe Register.
How often do I legally need a gas safety check?
Every 12 months, by law, for any rented property with gas appliances supplied by the landlord. The Gas Safety (Installation and Use) Regulations 1998 are the relevant regulations.
You must give the tenant a copy of the certificate within 28 days of the check, and within 28 days of a new tenant moving in.
What's the difference between a Gas Safety Certificate and a boiler service?
The certificate is a safety inspection of every gas appliance, required by law. A boiler service is a maintenance check of the boiler specifically: cleaning, testing efficiency, replacing worn parts where needed.
Different jobs, both annual, both done in one visit when paired. Booking them together means one engineer trip, one report, and a single £138 fee instead of two separate visits totalling £164 to £195.
What exactly is checked?
Every gas appliance the landlord supplies (boiler, hob, oven, fire, water heater), every flue or chimney those appliances vent into, and all the gas pipework connecting them. The engineer will also do a tightness test on the whole installation to check for leaks.
If your tenant has brought their own gas appliance (a portable heater, for example), that isn't covered, but the engineer can usually quote separately if you want it checked.
What happens if I miss the renewal date?
Renting without a valid CP12 is a criminal offence under the Gas Safety (Installation and Use) Regulations 1998. HSE fines start at £6,000 per property. Your insurance is likely voided. A section 21 notice issued without a valid certificate is unenforceable.
Renew before expiry. We send reminders 60, 30, and 7 days before your certificate runs out. Or, if you would rather never think about renewal dates again, Property Management Plus handles all your certificates automatically as part of full property management.
Why does it have to be Gas Safe registered?
Gas Safe Register is the UK's official registration body (it replaced CORGI in 2009). It's run on behalf of the Health and Safety Executive (HSE), and it's a legal requirement that any business or engineer carrying out gas work in the UK is on the register.
Every Gas Safe engineer has been trained, tested, and approved as competent. They must renew their registration annually and carry a current ID card. You can look up any engineer's credentials at gassaferegister.co.uk.
If anyone offers you a "gas safety check" without being Gas Safe registered, the certificate isn't legal and they're working illegally.
What's a CP12?
CP12 is the old name for the Landlord Gas Safety Record, and the name most people still use. It's the document the engineer gives you after the check, listing every appliance tested, the results, and any defects found.
If everything passes, the CP12 is your legal proof of compliance for the next 12 months. If something fails, the engineer will note the severity (At Risk, Immediately Dangerous, or Not to Current Standards) and what needs doing.
Does the £95 cover any repair work?
No. The £95 covers the check and the certificate. If the engineer finds anything that needs fixing, they'll quote separately. Anything classed as Immediately Dangerous will be disconnected on the day for safety, regardless of whether you go ahead with the repair through us or someone else.
How quickly can you book it in?
Most bookings happen within the same week. We coordinate access directly with your tenant. The engineer produces the CP12 on the day, and we email a copy to you and your tenant.
Do I need to be there?
No. We arrange access with your tenant directly. If the property is empty between tenancies, we can use a key from your safe, a key safe code, or coordinate with you.
My boiler is under warranty. Do I still need an annual service?
Almost certainly. Most manufacturer warranties (Worcester Bosch, Vaillant, Ideal, Baxi) require evidence of an annual service to remain valid. No service, no warranty cover if the boiler later fails. The written service record we issue is what the manufacturer will ask for.
NOT SURE WHICH CERTIFICATE YOU NEED?
Drop the team a note. We'll tell you what's required, what's not, and whether Management Plus makes more sense than buying certificates one at a time. No pressure.
SORT THE CP12. SLEEP EASIER.
