The kitchen tap the regulations actually require
Under the Water Supply (Water Fittings) Regulations 1999, premises supplied for domestic purposes must have at least one conveniently situated tap for drawing wholesome drinking water. The legislation permits supply from the specified wholesome-water arrangements and does not universally require a direct-mains tap over the kitchen sink.1 Separately, Drinking Water Inspectorate guidance supports retaining an unsoftened tap for drinking and cooking where a softener is installed.7
For appliances, verify the manufacturer’s integral backflow protection and the applicable fluid category, then add category-appropriate protection only where required. Before moving a sink, measure the proposed waste fall and distance to the stack, confirm venting and check whether the floor or cabinetry permits an accessible route. After installation, test tap pressure and temperature, fill the sink, check the trap and every joint, run appliance fill and drain cycles, and keep concealed valves and traps serviceable.1
The Dulwich Estate, and why the drinking tap matters here
Where the specific property is subject to The Dulwich Estate Scheme of Management, structural alterations may require a licence in addition to council approvals.34 Replacing units does not establish whether a new sink or waste route is viable; the actual structure, isolation and drainage route must be surveyed.
Thames Water confirms that the regional supply is hard.5 Limescale can affect some taps and appliances, but product selection and maintenance should follow manufacturer guidance. In a flat above a Lordship Lane food premises, the plumber should distinguish a local trap fault from a downstream shared waste and consider grease, rear access and the effect of isolation on both occupiers.
