Historic England lists buildings in three grades: Grade I for buildings of exceptional interest (about 2.5% of all listed buildings), Grade II* for particularly important buildings of more than special interest (about 5.8%), and Grade II for buildings of special interest (about 91.7%). Listing protects the whole building, inside and out.

Every entry on the National Heritage List for England whose point lies inside the ONS 2022 built-up-area boundary. One list entry can cover a terrace or a group of buildings. Neighbourhood dots: the population-weighted centre of each Census 2021 output area, coloured by its neighbourhood’s (LSOA’s) share of homes built before 1919 (Valuation Office Agency, March 2025).

Historic England’s conservation areas layer, supplied by councils (incomplete in places, so a page fact, never graded). Hectares are the part of each area inside the built-up area.

The first 6 entries were listed in 1949, 1 of the 7 Grade I buildings among them. 222 came in 1974, in the national resurvey of the 1970s and 80s. Only 14 have been added in the last 15 years.

3 scheduled monuments

Two measures, each ranked against every UK town of 1,000 or more, with protected heritage counting twice as much as the age of homes. Protected heritage counts each listed building by its grade (Grade I three points, II* two, II one), each scheduled monument and battlefield two, and each registered park or garden by its grade; it is ranked both per 10,000 residents and as a total, so a village with one fine church doesn’t outrank a historic city. The second measure is the share of homes built before 1919, from the Valuation Office Agency’s council tax records. History is a character grade: it describes the town and isn’t part of the overall grade.

1.9% of homes are Victorian or older, against 16% across England and Wales. The busiest period since was the 1930s, which added 30% of today’s homes.

Valuation Office Agency, council tax stock of properties by build period, 31 March 2025, for the neighbourhoods (LSOAs) that make up the town, split by where their residents live. Homes with no recorded build period (107 here) are left out; 1939–44 is not a period in the data.

The official list counts 396 listed buildings in Hillingdon, 7 of them Grade I, including Harmondsworth Great Barn. High Street alone has 22 listed buildings. Its older streets lie in 32 conservation areas, the first designated in 1969. Of the whole list, 60% are houses, terraces and villas.

Wentworth Webster (1828), Mary Bankes (1598) and John Dowson (1820) are among the 25 people born here before 1900. Its homes are mostly newer: 4.4% were built before 1919, against 15% in the typical UK town. More than half went on the list in a single year, 1974: 222 of 396. The rest is about typical: per resident it sits near the middle of UK towns; and it also has 3 scheduled monuments.
