A new boiler is a major investment that affects your heating bills and comfort for the next 10-15 years. We help you choose the right model for your home's size and needs, whether that's a condensing, combi, or system boiler.

Our engineers handle the full installation: disconnecting the old boiler, fitting the new one, commissioning it, and testing all safety features. We handle the Gas Safe certification so you have proof of safe installation.

We work with all major manufacturers and can source the best boiler for your budget and requirements. Installation typically takes one day, and we'll explain how to use your new system safely.

Why choose us: experienced installers, honest advice on boiler choice, full Gas Safe certification, warranty on parts and labour, and no hidden costs.

Our boiler stopped working on a Sunday evening. Test Plumbing was here within two hours, diagnosed the problem, and had us warm and comfortable before bed. Professional, friendly, and reasonable pricing.
