Frequently Asked Questions
What is a Gas Safety Certificate, and who needs it?
A Gas Safety Certificate (CP12) is a document issued by a Gas Safe registered engineer after inspecting your gas appliances to confirm they are safe to use. It is legally required for landlords to provide a certificate to their tenants annually. Homeowners are not required by law but are strongly encouraged to have regular checks for safety.
How often do I need a Gas Safety Certificate?
Landlords must obtain a Gas Safety Certificate every 12 months for each property they rent out. Homeowners should have their gas appliances checked annually to maintain safety and efficiency.
What happens during a gas safety check?
Our engineers inspect all gas appliances, including boilers, cookers, and gas fires. They check for gas leaks, proper ventilation, flue operation and correct system pressure. If everything meets the standards, we issue a Gas Safety Certificate.
How much does a Gas Safety Certificate cost?
The cost varies depending on the number of appliances to be inspected. At On Site Contractors And Plumbing LTD, we offer competitive and transparent pricing. Contact us for a free quote today.
