Landlord Certificates & Repairs in Northwood

Northwood housing stock

Northwood grew around its Metropolitan Railway station, which opened in 1887. Hillingdon's leaflet for the Northwood-Frithwood Conservation Area records that Frank Carew laid out the estate after the railway arrived, and that it is mainly large, individually designed detached houses in the Arts and Crafts style, some of the later ones by C.H.B. Quennell, Swannell and Sly, and John Markham, a pupil of Lutyens. That conservation area was designated in 1989 and extended on 2 December 2009. Northwood Town Centre, Green Lane became a conservation area on the same day in 2009, and The Glen, Northwood followed earlier, on 18 July 2007. Northwood Hills is a younger place. Its station opened on 13 November 1933 and housebuilding followed almost at once, on a more modest scale than old Northwood: mostly 1930s semis, with a few flat-roofed modernist houses. Valuation Office records for the small statistical area named Northwood Hills date a quarter of its homes to the 1930s and 29% to between 1945 and 1964, so post-war building stands alongside the interwar semis.

The area named Northwood is older: 16% of its homes went up between 1900 and 1918, and 19% before 1919 in all. Hillingdon also lists several Northwood streets as areas of special local character, a lighter, non-statutory designation: Copsewood Estate, Gatehill Farm Estate, Dene Road (13 November 1989), Old Northwood (31 March 2005) and Hillside, Northwood Hills (24 July 2008). The 2021 Census shows how different the two wards are. In Northwood ward, 29.6% of the 4,757 households lived in a detached house and 35.4% in a purpose-built block of flats, with only 11.8% in semis. In Northwood Hills ward, semi-detached houses were the largest group at 31.3% of 4,514 households, with detached houses at 27.5% and purpose-built flats at 25.5%. Private renting stood at 26.6% of households in Northwood ward and 22.6% in Northwood Hills, where 10.9% also rented from the council.

What that means for certificates and repairs

• Large detached houses in Frithwood and around Dene Road usually have long pipe runs, a cold water tank in the loft and more than one bathroom, so a slow leak can sit unseen for weeks. We trace it before cutting anything.
• Affinity Water's 2025 report for its Northwood supply zone gives total hardness of 348 mg/l as calcium carbonate. That is very hard water, and it shows up as scaled shower valves, sluggish cistern fill valves and crusted aerators.
• Inside the Northwood-Frithwood Conservation Area, Hillingdon asks that materials and window shapes match the original house, which shapes any external decorating or joinery repair we quote.
• Flats are the biggest single housing type in Northwood ward, so many jobs involve a managing agent, a leaseholder and shared risers. We confirm who owns the pipe or cable before starting.
• Since 24 August 2026 any Hillingdon HMO let to three or more people from two or more households needs a licence, so shared houses in HA6 need certificates that can be produced on request.
• Moor Park houses in HA6 fall under Three Rivers and the Moor Park (1958) Ltd covenants, not Hillingdon, so external work there needs checking against both.

Getting to you

From 6 Station Parade on Kenton Lane we usually head up to Harrow Weald, west along the Uxbridge Road through Hatch End to Pinner, and then out on the A404 past Northwood Hills into Northwood. It is about 6.6 miles by road, so Northwood Hills and the streets around Joel Street are the nearest part of HA6 for us, and Moor Park and the Gatehill end are the furthest. Hillingdon runs parking management schemes around both stations: zone N in Northwood and zone NWH in Northwood Hills.

Bays in those zones are for permit holders during the controlled hours, so tell us the zone when you book and whether there is room on your drive. The roads inside the Moor Park estate are private and owned by Moor Park (1958) Ltd, so let us know if we need to be expected at the gate.

Neighbourhoods we cover in and around Northwood include Northwood Hills, Frithwood, Gatehill Farm Estate and Moor Park, Hertfordshire.

Nearby areas we cover: Pinner, Ruislip, Bushey and Harrow.
