Why we set up Mr Reactive We set up Mr Reactive because we knew that there was a better way of supporting customers by delivering high quality home and boiler service plans. Our background as an experienced plumbing and gas engineering company means we're better placed than our competitors (including most boiler insurance providers) to deliver a premium home and boiler care service. Our technical knowledge and first hand front line experience are what sets us apart. It’s not just about boilers - we also provide flexible care plans for central heating, plumbing and more for both homeowners and landlords.
