Annual Boiler Servicing You Can Rely On

A yearly service keeps your boiler running safely, efficiently and exactly as the manufacturer intended — and in most cases, it's a condition of keeping your warranty valid.

Based in Porthmadog, Lloyds Plumbing & Heating provides annual servicing for homeowners and landlords across the Llyn Peninsula, with every visit carried out by a Gas Safe registered engineer.

We service all major makes and models, identify small issues before they turn into costly breakdowns, and leave you with the paperwork to prove it.

What's Included In A Service

A full annual boiler service covers everything needed to keep your system running safely and at peak efficiency.

Full visual inspection of the boiler and flue
Combustion analysis and gas pressure check
Internal component inspection and clean
Safety device and control testing
Identifying potential issues before they fail
Service record provided on completion

Gas Safety Certificates (CP12) for Landlords

If you let out a property in the UK, the law requires every gas appliance to be checked annually by a Gas Safe registered engineer — and a copy of the certificate must be issued to your tenants within 28 days.

We work with landlords and letting agents across Gwynedd to make this hassle-free, with prompt appointments, reliable turnaround on paperwork and competitive pricing for multiple properties.

Whether you manage one rental or a full portfolio, we'll keep you compliant, your tenants safe and your inbox clear of chaser emails..
