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).

Of the 176 entries, 85 are named by a street address; the rest are named buildings such as churches, halls and bridges.

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 41 entries were listed in 1951, 5 of the 7 Grade I buildings among them. 111 came in 1971, in the national resurvey of the 1970s and 80s. Only 4 have been added in the last 15 years.

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.

5.9% of homes are Victorian or older, against 16% across England and Wales. The busiest period since was 1965–72, which added 26% 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 (26 here) are left out; 1939–44 is not a period in the data.
