A stopcock for the water supply to your flat is in the cupboard outside your front door. It may be above head height rather than one lower down, which could control the water supply to the flat below you. The estate completely serviced and overhauled all stopcocks in 2007 and each one is now clearly labelled. Maintenance of the stopcocks is the responsibility of each lessee. Keys to those cupboards that have locks have been distributed to each flat, but if you do not have one, tell the estate office. The cupboards are not part of your property and must not be used for storage.
