Common Questions

How often do I need a gas safety certificate?

By law, every 12 months. The certificate (CP12) must be issued by a Gas Safe registered engineer and provided to tenants within 28 days.

Can you service the boiler at the same time?

Yes. We offer a combined gas safety check and boiler service at a discounted rate. It’s the most efficient option for landlords.

Do you offer discounts for multiple properties?

Yes. If you have several properties in the Cardiff area, contact us for a tailored rate.
