These are all the homes on each postcode, whatever their size and however many live in them, so they show the kind of homes and heating here rather than what any one home uses. The typical figure is the median: half the homes used less. The district is CV35.

Flood risk
Rivers, the sea or surface water: in this street's postcodes, 0 addresses are in areas at high risk, 1 at medium risk and 0 at low risk. Each address counts once, at the higher of its rivers-and-sea and surface-water risk.
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 on this street is in flood zone 2 or 3.
| Postcode | Planning zone | Addresses at high / medium / low risk | Groundwater |
|---|---|---|---|
| CV35 8QX | not in 2 or 3 | 0 / 0 / 0 | unlikely |
| CV35 8QT | not in 2 or 3 | 0 / 0 / 0 | unlikely |
| CV35 8QY | not in 2 or 3 | 0 / 1 / 0 | unlikely |
| CV35 8RB | not in 2 or 3 | 0 / 0 / 0 | unlikely |
Recorded floods
No recorded flood covers the centre of any of this street's postcodes.
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.
Coastal erosion
No projected coastal erosion zone is within 1 km (0.6 miles) of the street's postcodes.
Storm overflows
No storm overflow outlet is within 1 km (0.6 miles) of the street's postcodes.
Coal mining
No postcode centre on the street is in a coalfield: the Mining Remediation Authority records no coal mining risk here.
Radon
Every 1 km square the street's postcodes are in is 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.
Historic landfill
1 historic landfill site is within 500 m (0.3 miles) of the street's postcodes, the nearest 280 m away.
| Site | Waste went in | Waste | Distance |
|---|---|---|---|
| M40 Norton Lindsey/Land at Hampton Hill Farm Hampton Hill Farm, Wards Hill, Hampton on the Hill, Warwickshire | 1987 to 1990 | Inert, commercial | 280 m |
Closed tips can give off gas (methane and carbon dioxide) and leak into the ground for years. An environmental search, which conveyancers usually order, looks at landfill and contaminated land around the home; the council keeps a register of land it has found to be contaminated.
Height above sea level
The street's 25 addresses are between 67 m and 99 m above sea level (78 m on average); the ground rises about 33 m from the lowest to the highest.
Broadband
| Postcode | Superfast (30 Mbit/s+) | Ultrafast (300 Mbit/s+) | Gigabit | Below 10 Mbit/s |
|---|---|---|---|---|
| CV35 8QT | 100% | 43% | 43% | 0% |
| CV35 8QX | 17% | 0% | 0% | 0% |

Water
This street's water is supplied by Severn Trent. The company gives the hardness and quality of the water at an address on its website.
Severn Trent does not publish the hardness of its tap samples as open data; only Yorkshire Water, Wessex Water and Southern Water do.

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 Warwick: see them on the Warwick page.
Nearest schools
| School | Phase | Ages | Distance | Inspection | Exam results |
|---|---|---|---|---|---|
| Budbrooke Primary School | Primary | 4–11 | 1.6 km (1 mile) | No published inspection | 44% at the expected standard in reading, writing and maths, 6% at the higher standard (2025; 71% in 2024 and 68% in 2023) |
Exam results are from the Department for Education's school performance tables (Explore Education Statistics, Open Government Licence), for all pupils at each school. The middle school in England had 63% at the expected standard at the end of primary school (2025), Attainment 8 of 46.0 at GCSE (2026) and an A level average of C+ (2025). Attainment 8 adds up a pupil's grades in eight GCSEs, with English and maths counted twice (90 is the most), averaged over the school's pupils. Progress 8 compares pupils with others who had the same results at the end of primary school; it is not published for GCSEs in 2025 and 2026, as those pupils sat no primary tests during the pandemic. Small year groups swing from year to year, and figures for very small ones are withheld.
Nurseries and childcare
No nursery, pre-school or out-of-school club on Ofsted's register is within 1.5 km (0.9 miles) of the middle of the street.
Ofsted also registers 230 childminders and 39 home childcarers (nannies) in Warwickshire. It does not publish their addresses, so they cannot be shown here; the council's family information service lists those taking children.
Food hygiene ratings nearby
No rated food businesses within 500 m (0.3 miles).
Crime within 250 m
No crimes recorded at anonymised points within 250 m in this period (Warwickshire Police).
Policing
This street is policed by Warwickshire Police. Of the 39,478 crimes it recorded in 2025/26 (April to March), 7.6% had led to someone being charged or summonsed to court, against 9.3% across England and Wales.
In the 12 months November 2025 to October 2026 it answered 89.1% of its 112,690 999 calls within 10 seconds, against a national target of 90% and 89.6% across England and Wales.
| Outcome | Warwickshire Police | England and Wales |
|---|---|---|
| Charged or summonsed | 7.6% | 9.3% |
| Dealt with out of court (caution, community resolution, penalty notice) | 1.6% | 4.4% |
| Closed with no suspect identified | 35.8% | 37.8% |
| Closed: the victim did not support further action | 31.1% | 25.4% |
| Closed: suspect identified, but not enough evidence | 17.9% | 15.1% |
| Other outcomes (not in the public interest, transferred elsewhere) | 2.6% | 3.9% |
| No outcome yet (still under investigation) | 3.4% | 4.0% |
Each crime is counted under the outcome it had been given when the figures were taken, a few months after the year ended, so some recorded late in the year were still being investigated. Forces differ in the crimes they deal with (a city force has more shoplifting and fewer rural thefts), which changes these shares, so a difference from England and Wales is not by itself a measure of how well a force investigates. Fraud is not included: it is recorded nationally.
Road safety
3 collisions in which someone was hurt were reported on and around the street in 2021 to 2025: 0 fatal, 1 serious and 2 slight, in which 1 person was seriously hurt. 1 involved a cyclist; 1 involved a motorcyclist. Most were on roads with a 50 mph limit.
| Year | Collisions | Fatal or serious |
|---|---|---|
| 2021 | 0 | 0 |

| 2023 | 0 | 0 |

| 14 Jun 2025 10:33 | Serious | 1 person: 1 motorcyclist | A4189, 30 mph | Daylight |
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
No traffic count point is within 500 m (0.3 miles) of the street's postcodes. The Department for Transport counts every motorway and A road and only a sample of minor roads, so a quiet residential street usually has none.

Postcodes on this street
What this page cannot tell you
- Whether a particular house is at risk of flooding, subsiding or anything else: the flood map is a model of areas and there is no property-level data here.
- What a home is worth now: sales are historic prices for the homes that happened to sell.
- How safe the street is: crime points are moved to anonymised locations and many crimes are never reported; road collisions count only those in which someone was hurt and the police were told.
- Whether you would get a place at a school: distances are straight lines, not catchments.
- Who lives on the street now: census figures describe the small areas around it in March 2021, during a lockdown.
- How long a journey takes or how often anything runs: transport distances are straight lines to the nearest stops.
- Whether a GP practice is taking new patients, or a dentist new NHS patients.
- How loud a home is inside, or noise from industry, neighbours or smaller airfields: noise figures are models of road, rail and air traffic outside.
