The Quiet Revolution

Over the years, as more households have moved to having their boilers installed in the kitchen, the noise of home appliances has become more important to us all. With many of us having our boiler in our kitchen, and us all spending more time than ever living and working at home, the desire for ‘quiet’ products has accelerated.

We’ve worked hard on continuously innovating and improving our products, and we’ve made great strides in ensuring our boilers are quieter now than ever before. We’re thrilled to announce that we are now Quiet Mark certified for a number of our boilers. You can find out more info below on the exact products that are now Quiet Mark certified.

This is SO much better than our old boiler, it's almost ridiculous. It's so quiet (and it's in our bedroom so we are more than aware of noise), much cheaper and heats our flat instantly. Have no problems at all recommending!!
