Boiler Servicing & Repairs Cardiff & South Wales

Keep Your Boiler Running Safely and Efficiently

Regular boiler servicing is essential for maintaining efficiency, preventing breakdowns, and ensuring your family's safety. At Hollis Plumbing and Gas Ltd, we've been servicing and repairing boilers across Cardiff and South Wales for over 22 years. Our Gas Safe registered engineers have the expertise to keep your heating system in peak condition.

Comprehensive Boiler Servicing

An annual boiler service is the best way to prevent costly breakdowns and maintain your manufacturer's warranty. During our thorough service, we'll inspect all components, clean vital parts, check for potential issues, and ensure your boiler is operating safely and efficiently.

Our servicing covers all major boiler brands including Baxi, Worcester Bosch, Alpha, and Vaillant. We'll provide you with a detailed report and Gas Safe certificate upon completion, giving you complete peace of mind.

Fast, Reliable Boiler Repairs

When your boiler breaks down, you need a swift response from engineers you can trust. Our experienced team diagnoses and repairs faults quickly and effectively, getting your heating and hot water back up and running with minimal disruption.

Common boiler repairs we handle:

No heating or hot water – We'll identify whether it's a component failure, pressure issue, or thermostat problem and resolve it promptly.

Strange noises – Banging, whistling, or gurgling sounds often indicate underlying issues that need professional attention.

Leaking boilers – Water leaks can cause serious damage. We'll locate the source and carry out repairs to prevent further problems.

Pressure problems – Low or fluctuating pressure can affect performance. We'll investigate and rectify the cause.

Pilot light issues – If your pilot light keeps going out, we'll identify and fix the fault.

Landlord Gas Safety Certificates

As a landlord, it's your legal responsibility to ensure gas appliances are checked annually. We provide comprehensive landlord gas safety certificates, inspecting all gas appliances and providing the documentation you need to comply with regulations.

"Their work was exceptional and exceeded my expectations. In just 2 days, they removed my gravity-fed tank and boiler, replaced all radiators, and flawlessly installed two additional “designer” radiators that I purchased separately."
