House prices and rents in Westminster

Sources: UK House Price Index (HM Land Registry, with the ONS and the Welsh Government), to August 2026; ONS Price Index of Private Rents, to September 2026. Figures for the whole council area. The typical price is adjusted for the mix of homes that sold, so it is not the value of any one home. Rents are the average paid on all private tenancies, new and existing, so they move more slowly than rents being advertised.

Council tax

What each band costs in Westminster in 2026-27: Band D £1,050 a year on average, including the police, fire and any county and parish charges.

Homes by band in the neighbourhood around this postcode: most are in band G (48% of about 1,170 homes).

Sources: Valuation Office Agency, Council Tax: stock of properties, homes at 31 March 2026 (counts rounded to the nearest 10; some small counts withheld), for the neighbourhood (census area of about 700 homes) around it, not just this postcode; Ministry of Housing, Communities and Local Government, council tax levels 2026-27. Bands are charged as fixed shares of Band D; the actual bill depends on the parish and on discounts such as the single-person discount.

Energy projects nearby

1 energy project near the postcode, 1 of it not yet operating.

Planned projects can change or not go ahead; search the planning authority's applications by the reference shown for the plans, conditions and any objections. Construction brings traffic for some months; once built, solar farms and batteries are usually quiet, while turbines and waste plants can be seen or heard further away.

Source: Department for Energy Security and Net Zero, Renewable Energy Planning Database, Q2 2026 extract, Open Government Licence: renewable electricity and storage projects over 150 kW, operating, being built, permitted or applied for. Shown: wind turbines and plants that burn or digest waste within 5 km (3.1 miles), other projects of 1 MW or more within 2 km (1.2 miles); refused, withdrawn and abandoned projects are left out. Distances are from the nearest postcode centre to each project's grid reference.

Flood risk

No address in this postcode is in an area at high, medium or low risk of flooding from rivers, the sea or surface water. The rest are in areas at very low risk: less than a 0.1% (1 in 1,000) chance a year.

Rivers and the sea alone: no home is in an area at risk.

High: 3.3% (1 in 30) or more chance of flooding a year. Medium: 1% to 3.3%. Low: 0.1% to 1%. Very low: under 0.1%. The rivers and sea figures allow for flood defences. Counts cover whole postcodes, which can include other streets.

Flood zone for planning: no postcode centre is in flood zone 2 or 3.

Recorded floods

No recorded flood covers the centre of this postcode.

Recorded floods are where floodwater was seen or surveyed after a flood. Many floods were never mapped, an outline over a postcode's centre does not mean every home in it flooded, and homes outside one may have. Ask the seller whether the home itself has flooded.

Sources: Environment Agency Recorded Flood Outlines; Environment Agency Flood risk: postcode search tool data (loaded 29 October 2026), Risk of Flooding from Rivers and Sea: postcodes in areas at risk (loaded 29 October 2026) and Flood Map for Planning (loaded 28 October 2026). Flood zones are checked at each postcode's centre point. These are models of areas, which their publishers say are not suitable for showing whether an individual property is at risk, and they do not cover flooding from sewers or drains.

Coastal erosion

No projected coastal erosion zone is within 1 km (0.6 miles) of the postcode.

Sources: Environment Agency, National Coastal Erosion Risk Mapping 2024 (England), and Natural Resources Wales, National Coastal Erosion Risk Management (Wales), Open Government Licence. Distances are from the nearest postcode centre to the edge of each zone; where a postcode centre is inside a zone, some homes on it may not be.

Storm overflows

No storm overflow outlet is within 1 km (0.6 miles) of the postcode.

Source: Environment Agency, Event Duration Monitoring storm overflow annual return for 2025, from the water companies' monitors on each overflow in England, Open Government Licence. Distances are from the nearest postcode centre to each overflow's outlet. A year's figures are published the following spring; a monitor that worked for less of the year undercounts.

Coal mining

No postcode centre here is in a coalfield: the Mining Remediation Authority records no coal mining risk here.

Source: Mining Remediation Authority (formerly the Coal Authority), development high and low risk areas, Open Government Licence. Checked at each postcode's centre, so a home near the edge of an area may differ. It covers coal mining only, not other mining (such as tin, lead, iron or chalk), and is no substitute for a coal mining search. About the risk areas.

Radon

The postcode is in a 1 km square in the lowest band of radon potential: fewer than 1 home in 100 is estimated to be at or above the Action Level. It is not a radon Affected Area.

Source: British Geological Survey and UK Health Security Agency, Indicative Atlas of Radon in Great Britain, Open Government Licence. Contains British Geological Survey materials © UKRI 2026. Each 1 km square is classed by the highest radon potential found anywhere in it, so a square's figure can overstate it for much of the square; the detailed map is not open data.

Gas and electricity use

The postcode does not have the 5 or more domestic meters needed for figures to be published.

Source: Department for Energy Security and Net Zero, postcode level domestic gas and electricity statistics for 2024 (gas from mid-May to mid-May), Open Government Licence: domestic meters on each postcode, from the gas and electricity industry's meter readings. A postcode with fewer than 5 meters of a fuel has no figures for it.

Historic landfill

No historic landfill site is within 500 m (0.3 miles) of the postcode.

Sources: Environment Agency and Natural Resources Wales, historic landfill sites (places where waste was put into or onto the land and no environmental permit is now in force), Open Government Licence. Distances are from the nearest postcode centre to the edge of each site as mapped; the outlines and dates come from old records and can be approximate. Landfill still operating is not included.

Height above sea level

The postcode's addresses are about 26 m above sea level.

Source: Ordnance Survey, OS Terrain 50, July 2026: the height of the ground on a 50 m grid, read at each address, in metres above Ordnance Datum (mean sea level at Newlyn). It is the lie of the land, not floor or threshold levels, and is accurate to a few metres. Being low-lying is not in itself a flood risk; the flood section above says what the flood maps show.

Distances are straight lines from the postcode's centre, not routes, and say nothing about how often anything runs. Stations opened since the end of ORR's year appear when ORR publishes the next one, each December; heritage railways are left out.

Local services

Sources: NHS Organisation Data Service, as at 31 October 2026: GP practices, community pharmacies and dental practices with an NHS contract, open now, each placed at the centre of its postcode; hospitals are NHS trust and Welsh health board sites named as hospitals, and may not have an emergency department. Ratings and care homes: Care Quality Commission, latest ratings as at 2 November 2026 (England only; the CQC does not rate dental practices, and Wales's inspectorates give no ratings). Police stations and cash machines from Overture Maps Foundation, release 2026-10-21.0, which gathers business listings: not an official register, so some will be missing or out of date. Distances are straight lines from the postcode's centre. Nothing here says whether a practice is taking new patients or a dentist new NHS patients.

Nurseries and childcare

The ten nearest nurseries, pre-schools and clubs are all within 1 km (0.6 miles); the nearest is 120 m from the postcode's centre.

Ofsted also registers 44 childminders and 23 home childcarers (nannies) in Westminster. It does not publish their addresses, so they cannot be shown here; the council's family information service lists those taking children.

Source: Ofsted, childcare providers and inspections management information, as at June 2026, Open Government Licence: providers on the Early Years and Childcare Registers on non-domestic premises, placed at their postcode. Since November 2025 Ofsted gives a standard for each of six areas (Exceptional, Strong, Expected, Needs attention, Urgent improvement) rather than one overall grade; older grades stand until a provider is inspected again. Distances are straight lines from the postcode's centre.

Parks and green space

Source: Ordnance Survey, OS Open Greenspace, April 2026: public parks and gardens, play spaces, playing fields and allotments, with their entrances. Distances are straight lines from the postcode's centre to a site's nearest entrance (or its edge where none is recorded), not walking routes; sizes are the area OS maps for each site. Some sites, such as school playing fields, may not be open to the public.

Within 800 m (0.5 miles): 12 parks and gardens, 151 hectares in all.

Landmarks

The nearest historic landmark is 107 and 109, Harley Street W1, a listed building (Grade II*), 140 m north-east. 871 listed buildings are within 1 km (0.6 miles), 45 of them Grade I and 62 of them Grade II*.

Sources: Historic England's registers through planning.data.gov.uk (MHCLG), and Cadw through DataMapWales (Welsh Government): World Heritage Sites within 10 km (6.2 miles), battlefields within 5 km (3.1 miles), registered parks and gardens within 3 km (1.9 miles), scheduled monuments within 2 km (1.2 miles), and Grade I and II* listed buildings within 1 km (0.6 miles). Ordnance Survey, OS Open Names, October 2026: named hills, valleys, lakes, woods, wetlands and coast (it has no rivers). Distances are in a straight line to the middle of each site, and being on a register does not mean there is public access.

Air quality

Source: Defra, modelled background air pollution, annual means for 2024, for the 1 km square that holds the postcode's centre. These are background levels, away from the kerb: beside a busy road nitrogen dioxide in particular can be several times higher. UK limits are the legal annual limits for England and Wales; the World Health Organization's 2021 guidelines are much stricter, and most towns and cities are above them.

All three are within the UK legal limits; all three are above the WHO guideline, as in most towns and cities.

Road, rail and aircraft noise

Source: Defra, strategic noise mapping Round 4 (England), modelled for 2021 and published in December 2023, and its airport maps of the same round for the fifteen largest English airports, published in April 2026: Lden, the average sound level over a whole day with extra weight for the evening and night, on a 10 m grid, read at each address. These are models of traffic, not measurements; they leave out smaller airports and airfields, industry and neighbours, and a room at the back of a house is often much quieter than the front. The World Health Organization's guidelines are 53 dB for road traffic, 54 dB for railways and 45 dB for aircraft (below the lowest level shown here).

4 of the postcode's 4 addresses are modelled at 55 dB or more from road traffic, above the WHO guidelines.

Road safety

Source: Department for Transport, road safety data (STATS19), collisions in 2021 to 2025, as published by November 2026. Collisions in which someone was hurt and which were reported to the police, within 250 m of the postcode's centre. Severity is the worst injury as the police recorded it.

39 collisions in which someone was hurt were reported around the postcode in 2021 to 2025: 0 fatal, 9 serious and 30 slight, in which 9 people were seriously hurt. 12 involved a pedestrian; 13 involved a cyclist; 8 involved a motorcyclist. 23% happened in the dark, and 13% on a wet or icy road. Most were on roads with a 20 mph limit.

Only collisions in which someone was hurt and which the police were told about are here: damage-only collisions and near misses are not, and some injuries are never reported. Positions are recorded by the police, usually to within a few metres. Each year's figures are published the following September.

Traffic on nearby roads

The busiest counted road within 500 m (0.3 miles) is the A501 between Baker St and Park Crescent (mid-junction), with 42,783 motor vehicles a day on average in 2025, 500 m (0.3 miles) from the postcode.

Each figure is the annual average daily flow: the motor vehicles passing the count point, both ways, on an average day of the year. A point is counted by hand on a weekday every few years and estimated from the trend on similar roads in between. Lorries are heavy goods vehicles, as a share of all motor vehicles.

Climate, daylight and earthquakes

Monthly temperatures and rainfall, sunrise and sunset through the year, and earthquakes recorded nearby since 1970 are much the same across the area, so they are worked out once for Westminster: see them on the Westminster page.

People and work

Source: ONS Census 2021, taken on 21 March 2021, for the Output Area (a small census area of about 125 households) that this postcode is in: 202 residents in 101 households. The census was taken during a lockdown, so working from home is high and travel to work low compared with now. ONS swaps a few records between neighbouring areas and adds small amounts of noise to counts to protect privacy, so small differences mean little. Industry is not published for areas this small.
