Landlord Gas Safety Certificates in Hertfordshire

A standard CP12 inspection (boiler plus up to two additional appliances) is £85 ex VAT. Each additional appliance beyond two is £20 ex VAT. A combined CP12 and annual boiler service is £170 ex VAT — the most popular option for landlords, as it satisfies both legal obligations in a single visit. Portfolio landlords with three or more properties benefit from negotiated bulk rates — call to discuss.

Every 12 months. The Gas Safety (Installation and Use) Regulations 1998 require an annual inspection of all gas appliances in every rental property. You can renew up to two months early and retain the original expiry date — so if your certificate expires on 1 December, you can have the inspection done in October and the new certificate will still run until the following 1 December.

Failing to hold a valid annual gas safety certificate is a criminal offence under the Gas Safety (Installation and Use) Regulations 1998. Penalties include an unlimited fine (typically £6,000 or more per offence) and up to 6 months' imprisonment. Beyond the criminal penalties: you cannot legally serve a Section 21 notice to recover possession of the property; most landlord insurance policies are invalidated; and you face personal civil liability if a tenant is injured or killed as a result of a gas incident.

No. Under the Deregulation Act 2015 (applicable to tenancies starting after 1 October 2015) and the Renters' Reform Act provisions, a landlord cannot validly serve a Section 21 notice unless a copy of a current gas safety certificate was provided to the tenant at the start of the tenancy and within 28 days of each subsequent annual inspection. If a certificate was not provided at the correct time, you may be unable to recover possession via Section 21 even if the certificate is renewed later.

Yes — virtually all landlord insurance policies in the UK require a current Gas Safety Certificate to be in force. In the event of a claim related to a gas incident (fire, explosion, CO poisoning), your insurer will ask for the CP12. If it has lapsed or was never obtained, the policy is likely to be void and you will have no cover. Check your specific policy wording.

You must take all reasonable steps to gain access. Document every attempt in writing — letter, email or text message with dates and times. If a tenant repeatedly refuses access without reasonable cause, you can apply to the court for an injunction to allow entry. You will not be prosecuted for failing to carry out an inspection if you can demonstrate you took all reasonable steps to gain access and the tenant refused. We can assist by contacting tenants directly and offering flexible appointment times.

Yes. A CP12 Gas Safety Record is issued per property, not per landlord. Each property requires its own annual inspection and its own certificate. If you own multiple properties, we offer coordinated scheduling and a single invoice for the batch — reducing your administrative burden significantly.

Yes. Under the Gas Safety (Installation and Use) (Amendment) Regulations 2018, you can provide a CP12 to your tenant electronically (email or a shared document) if the tenant agrees to receive it that way. If the tenant has not agreed, you must provide a hard copy. We issue digital certificates by default and can copy your tenant directly if you provide their email address.

If an appliance is classified as Immediately Dangerous (ID), our engineer will cap it off at the visit — it cannot be left connected. You are required to have it repaired or replaced before it is brought back into service. If an appliance is At Risk (AR), the tenant is informed in writing and you are strongly advised to have it repaired promptly. Failure to act on an At Risk notice and a subsequent gas incident could result in serious criminal and civil liability.

HMOs (Houses in Multiple Occupation) require annual CP12 inspections in the same way as standard rental properties. However, communal areas, shared boilers serving multiple units, and any communal gas appliances must all be included in the inspection. Large HMOs with multiple gas supplies may require a more detailed inspection than a single-family let. Call us to discuss your specific HMO requirements.

Yes. The Gas Safety (Installation and Use) Regulations 1998 apply to all properties let in the course of a business, which includes short-term holiday lets and Airbnb properties. If you let a property for holiday or short-term use and it has gas appliances, you must have a current Gas Safety Certificate. The annual requirement applies regardless of how frequently the property is occupied.

Yes. We have dedicated accounts for letting agents managing multiple landlord portfolios. We offer coordinated scheduling across properties, direct certificate delivery to letting agent systems, a single invoice per billing cycle and discounted rates for volume. Landlords with 3–9 properties receive a 10% discount; 10–19 properties 15%; and 20+ properties are quoted individually. Call to set up a letting agent account.

A CP12 (Gas Safety Record) is a legal compliance document confirming that all gas appliances are safe — it is a pass/fail safety check, not a maintenance service. A boiler service is a maintenance visit that cleans the boiler, checks performance, replaces wear parts and ensures the boiler is operating efficiently. The boiler service is not a legal requirement for landlords (though it is required by many boiler manufacturer guarantees) but is strongly recommended. Most landlords combine both in a single visit — our CP12 + boiler service bundle covers both obligations for £170 ex VAT.

No — a Gas Safety Certificate is only required for properties that have gas appliances or a gas supply. If the property has electric heating only and no gas appliances (no gas cooker, no gas hob, no gas fire), no CP12 is needed. However, if there is a gas meter or any gas appliance present — even rarely used — it must be included in an annual inspection.

We understand that certificates are often needed urgently between tenancies. We aim to attend within 24–48 hours of booking across Hertfordshire. The CP12 is issued the same day as the inspection. Call us directly for urgent bookings — we will do our best to accommodate you.
