Your legal obligation as a landlord
A landlord gas safety certificate, also called a CP12, is your annual legal confirmation that every gas appliance, flue, and pipework in your rental property has been professionally checked and is safe to use.
It's a requirement under the Gas Safety (Installation and Use) Regulations 1998. Meet it, and your tenants are protected, your property is covered, and you can move on with complete confidence.
We issue your certificate on the day and handle your tenants' copy too. One visit. Done properly.

Our Engineers
Experienced Engineers
Boilers On-Demand is backed by a team of engineers with over 36 years of hands-on experience carrying out landlord gas safety certificates across Sussex and Surrey. That depth of experience means your inspection is completed accurately, efficiently, and to the highest standard, first time, every time.
For landlords, this means reliable advice, clear communication, and the confidence that comes from knowing your property is in the hands of engineers who genuinely know what they're doing. We'll remind you when your renewal is due, so staying compliant is always one less thing on your plate.
Legal Requirement
Do Landlords Need a CP12 Certificate Every Year?
Yes. Under the Gas Safety (Installation and Use) Regulations 1998, every landlord with gas appliances in a rental property is legally required to have them inspected once every 12 months. The inspection must be carried out by a Gas Safe registered engineer.
Missing this deadline doesn't just put your tenants at risk — it can result in fines, prosecution, and voided landlord insurance. Your certificate must be renewed before it expires, not after.
Transparent Pricing
How Much Does a Landlord Gas Safety Certificate Cost in Sussex and Surrey?
Our pricing depends primarily on the number of gas appliances in the property. There are no call-out charges, no day-of surprises, and no hidden fees — you'll know exactly what you're paying before we visit.
For a standard property with one boiler and a gas hob, our rates are competitive and fully transparent. Call us or submit a quick quote request and we'll give you a clear figure within minutes.
What We Check
What Does a Gas Safety Check Include?
A thorough CP12 inspection covers every gas appliance, flue, and pipe in your rental property. Here's exactly what our Gas Safe engineers assess:
- Boiler operation, pressure, and combustion performance
- All gas appliances — hob, cooker, gas fire
- Pipework condition and tightness test
- Flues, ventilation, and combustion air supply
- Carbon monoxide and safety devices
- Emergency controls and shut-off valves
If everything passes, your CP12 certificate is issued on the same day. If we find a problem, we'll explain it clearly and advise on next steps — no unnecessary pressure, just honest advice.
Save Time
Landlord Gas Safety Certificate and Boiler Service Combined
Many landlords combine their annual CP12 inspection with a full boiler service in the same visit. It saves a second appointment, reduces disruption to tenants, and keeps everything in order at once.
Our engineers are equipped to carry out both in a single visit — the gas safety check is completed first, followed by the annual boiler service. You'll leave with both your CP12 certificate and a serviced, safe boiler.
Protect your property & tenants with annual checks
Landlord gas safety certificates (CP12) are valid for 12 months. Don't risk voiding your insurance or facing legal action. Our Gas Safe engineers provide fast, thorough inspections with digital records and same-day certification.
