Gas Safety Checks & Certificates in Leeds and Surrounding Areas
Keep your property safe, compliant, and rent-ready with a Gas Safety Certificate (CP12). Our team of Gas Safe registered engineers conducts thorough gas safety checks on all gas appliances, flues, and ventilation systems, and issues a compliant certificate you can proudly display.
What is a Gas Safety Certificate?
- A Gas Safety Certificate (CP12) is an official record confirming a gas safety check has been completed by a Gas Safe registered engineer.
- The certificate verifies that your gas appliances, flue, and ventilation meet safety standards.
- It is valid for 12 months and is required for rental properties in many jurisdictions. If faults are found, remedial actions must be completed and re-tested.
Who needs it?
- Landlords and property managers renting out homes or flats.
- Property owners who let properties to tenants.
- Any property owner needing a routine, legally compliant gas safety check.

What’s checked during the safety visit?
- Gas appliances: boilers, gas fires, cookers, and other installed gas appliances.
- Gas supply connections and pipework.
- Flues and vents to ensure proper venting and safe exhaust.
- Safety devices, such as pressure relief devices and minimum ventilation measures.
- Overall installation for signs of wear, leakage, or hazardous conditions.
Note: If any faults are found, the engineer will explain the issue, recommend remedial actions, and schedule a re-test after work is completed.
What you receive
- A completed CP12 certificate (digital and/or hard copy) detailing the property, appliances checked, results, and any remedial recommendations.
- A clear list of required actions and next steps, with dates for re-inspection if needed.
- A digital onboarding of the certificate for your records and to share with tenants, insurers, or local authorities as required.

Frequently Asked Questions
Do landlords legally need a gas safety check every year?
In many regions, yes. Landlords are typically required to have an annual gas safety check and provide a CP12 certificate to tenants. Local rules can vary, so verify your obligations.
What happens if the check fails?
The engineer will list faults and recommended remedial actions. The property must be repaired and re-tested before the certificate remains valid.
Can I book if the property is empty?
Yes. We can conduct checks on vacant properties, and issue certificates for prospective tenants or compliance records.
Do I need a CO detector?
Carbon monoxide detectors are strongly recommended where gas appliances exist. Regulations vary by location, so we can advise specific requirements for your area.
