That’s why we offer affordable, reliable cover options starting from just £8.50 per month, giving you complete peace of mind and protection when you need it most.
Our plans include an annual boiler service carried out by our Gas Safe-certified engineers to ensure your system is operating safely, efficiently, and at peak performance. Regular servicing not only reduces the risk of unexpected breakdowns but also helps extend the lifespan of your boiler and keeps your energy bills lower.
