Flow Switch

Flow switches are essential components in gas boiler systems, helping to detect water flow and protect the appliance from dry firing or overheating. At Hanicks, we stock a wide range of flow switches and associated parts for popular boiler brands, including Ideal, Baxi and Vokera. Whether you need a complete flow switch assembly, a flow sensor or a flow regulator, you will find the right part for your boiler model. Our technical team checks fitment before dispatch, so you can order with confidence. We offer OEM genuine, compatible, refurbished and obsolete parts, covering both current and older boiler models. In-stock orders placed by 4pm Mon–Fri (10:30am Sat) are despatched the same day. We offer 30-day returns on most items. For trade customers, our Doncaster counter is open Monday to Friday and Saturday morning.
