How Often Do You Need a Gas Certificate?
By law, landlords must renew their Gas Safety Certificate every 12 months. We recommend scheduling it a few weeks before the expiry date to allow time for any repairs or servicing if needed.
Homeowners should also consider an annual boiler service — it’s the best way to ensure your gas system remains efficient, safe, and within manufacturer warranty terms.
Safety and Peace of Mind
A faulty gas appliance can produce carbon monoxide, a colourless, odourless gas that can be deadly. Regular checks by qualified professionals protect you, your tenants and your property.
We also supply and fit carbon monoxide alarms during your visit if required — a simple, affordable way to enhance safety in your home or rental.
