What is a landlord gas safety certificate?
A landlord gas safety certificate, officially called a Landlord Gas Safety Record (LGSR) and still widely known as the CP12, is a legal document that proves a rental property’s gas appliances and flues have been checked for safety.
In plain terms, a Gas Safe registered engineer inspects every gas appliance and flue in the rental property and records the results. This record shows that the landlord has met their legal duty under the Gas Safety (Installation and Use) Regulations 1998. The document lists each appliance checked, any defects found, the engineer’s Gas Safe registration number, and the dates of inspection and the next required check. Keeping this record up to date is essential for staying compliant, protecting tenants, and avoiding penalties.
Your legal obligations as a Richmond landlord
In practical terms, missing gas safety duties can lead to HSE enforcement and fines, and in England a missing or invalid gas safety record can also affect Section 21 possession notices.
Arrange a gas safety check every 12 months on every gas appliance and flue you own
Keep it simple: one visit, one record, one clear paper trail
Give tenants a copy within 28 days of the check; for new tenants, provide it before they move in
Keep gas safety records for at least 2 years
Renew before the current record expires - a lapsed check leaves you non-compliant from day one, not just from the anniversary date
Book early if needed: checks done in the final 2 months before expiry keep the original renewal date, so you lose no time by staying ahead
Use only a Gas Safe registered engineer for the inspection and record
What does our gas safety inspection cover?
Gas safety inspections are done per appliance. Appliances that undergo a landlord gas safety check include boilers, gas hobs, gas fireplaces, gas cookers, and gas space heaters. The engineer runs a gas tightness test at the meter, checks standing and working pressure, measures burner pressure and gas rate, performs flue flow and spillage tests, verifies ventilation, tests operation of safety devices, and records the physical condition of the appliance and pipework.
Do note that the check is only done on appliances owned by the landlord, and not by the tenant. However, we do check the condition of flues serving the appliances. For a property with 1 gas appliance, a gas safety inspection typically takes from 1 hour. The engineer labels any unsafe appliance on the spot and reports it in the record, so you know exactly what needs attention before the property is let again.
How the visit works for landlords who don’t live locally
Most Richmond landlords don’t live in the rental property. In those cases, we book by phone or WhatsApp, where we’ll contact the tenant directly to arrange a convenient appointment time.
Our Gas Safe engineer attends with full ID verification, so access is secure.
Once the gas safety check has been done and there are no identified problems, the digital Landlord Gas Safety Record (CP12) certificate is emailed to you (and your agent, if applicable) the same day – paper copies available on request. We keep a secure digital record on file and send proactive annual reminders before renewal, so you never miss a compliance deadline.

What Happens If the Check Finds a Problem?
Defects are common and usually manageable, and completing fixes is a normal landlord maintenance routine. If our engineer spots an issue, it’s clearly classified (e.g., “Immediately Dangerous” or “At Risk”), the unsafe appliance is labelled and may be disconnected, and the defect is recorded on your Landlord Gas Safety Record (CP12) with a straightforward explanation of what needs fixing.
We’ll then quote the repair separately – see our boiler repairs in Richmond page for details. If the boiler cannot be safely repaired and is condemned, our new boiler installation in Richmond service covers your next steps.

Frequently Asked Questions
How often does a landlord need a gas safety certificate?
Every 12 months – one check per year on every gas appliance and flue in the rental property.
How much does a landlord gas safety certificate cost in Richmond?
Our Landlord Gas Safety check costs from £160 (plus VAT) for a property with one gas appliance, plus £30 (plus VAT) for each additional appliance – including all safety tests, tenant liaison and the digital certificate. We will provide a written quote before any work is done. No hidden extras.
How long does a gas safety check take?
Usually from 1 hour for a typical Richmond rental with one boiler and a gas hob. Larger properties or multiple appliances take longer. We usually email the gas safety certificate on the same day, so your paperwork is complete before the engineer leaves the street.
Is a Gas Safety Check (CP12) the same as a boiler service?
No. A gas safety check is a legal safety inspection that tests appliances and flues and records the results. It does not include internal cleaning or maintenance of the boiler. They are different jobs. Many landlords book an annual boiler service separately.
What do I need to arrange before the visit?
Almost nothing – give us the property address, tenant contact details and the number of gas appliances, and we arrange access directly with the tenant. We will have to discuss with you if keys are held by an agent. We will provide the gas safety certificate by email once the check is complete.
What if my tenant refuses access for the gas safety check?
You’re still legally responsible for arranging the check, even if a tenant refuses access. HSE guidance requires landlords to take all reasonable steps to gain entry – this typically means:
- Written requests (letter, email, or text) offering at least two proposed dates
- A minimum of 21 days’ notice for the visit, with a follow-up reminder
- A final letter warning that continued refusal may affect the tenancy agreement
Keep a written record of every attempt – dates, method of contact, and tenant responses. This record is your evidence that you met your legal obligation if the certificate lapses through no fault of your own.
We can flex around your tenant’s schedule, including evenings or weekends where needed, to make access easier to arrange.
Do I need a certificate if the property only has a gas boiler and no other gas appliances?
Yes. The annual check applies to every gas appliance and flue the landlord owns – a single gas boiler still requires a full gas safety check and Landlord Gas Safety Record (CP12). Properties with no gas supply at all do not need one.
Landlord gas safety checks have to be done regularly. We handle the tenant, and you get the certificate. Book your gas safety check today, call Dinate Engineering at 02082 400 557 or 07860 648 433.
