Our history


When Hattie Hasan started Stopcocks in 1990 its central pillars were respect, peace of mind, quality service and aftercare. We believed then (and we all still do) that you, your home and your time deserve respect and the highest quality services. Customers deserve better than the treatment we know they traditionally receive from plumbers and other tradespeople. By standing for quality customer service we aim to change the culture of the manual trades, especially of traders who come into your sanctuary, your home.

Stopcocks Women Plumbers mission has always centred on serving our customers. Although our mission has grown, nothing has changed and these four pillars remain at the centre of our approach.

Our customer service goes so far that, if we receive a request for a woman plumber in an area where we don’t have one, we will immediately look for one for you through our sister company the Register of Tradeswomen CIC
