Water and pipes

Thames Water's 2025 report for the Muswell Hill and Hampstead Heath supply zone gives a hardness range of 254 to 275 mg/l, mean 263 mg/l, in the 'hard' band. Check your own postcode, because supply zones do not follow postcode boundaries. (Source: Thames Water, 2025 water quality zone reports (Holloway, Crouch End and Gospel Oak, Kentish Town, Muswell Hill and Hampstead Heath); Thames Water, Hard water)

Homes built before 1970 may have a lead supply pipe. Thames Water will replace its own section free if you replace yours and meet its criteria; the scheme is closed over winter and due to reopen in spring 2027.

Good to know in N6

• Much of N6 is in the Highgate Conservation Area, so external flues, new pipe runs on front walls and air source heat pumps may need planning advice first.
• Highgate ward is not in Haringey's selective licensing scheme, but Haringey's additional HMO licensing covers all wards.
• Steep streets and large older houses mean long pipe runs and older heating systems. Ask for a written quote that lists any power flush or system upgrade separately.
