Your boiler is one of the most important systems in your home. When it breaks down, the cold and lack of hot water are immediate problems. Test Plumbing Co's engineers are trained on all major boiler brands and models.

We start with a thorough diagnostic to identify the fault. Common issues include pilot light failure, thermostat problems, and pump breakdowns. We explain what's wrong and show you repair options before we start work.

We also offer annual boiler servicing to keep yours in top condition. A service includes a safety check, internal clean, and efficiency test. It helps prevent breakdowns and ensures your boiler is legally safe to operate.

All our boiler work is carried out by Gas Safe registered engineers. We use genuine parts and provide a warranty on all repairs. Your safety and comfort are our priority.
