Gas and electricity use
Homes with gas used 10,275 kWh of it on average in 2024, 16% more than the district's 8,881 kWh, and 5,389 kWh of electricity, 15% more than the district's 4,667 kWh. There are gas meters for about 11% of the homes.
1 of its postcodes has no gas meters recorded among 10 or more homes: often flats heated by electricity, or homes off the gas grid.
| Postcode | Electricity meters | Typical electricity | Gas meters | Typical gas |
|---|---|---|---|---|
| TR9 6LG | 21 | 3,741 kWh | none recorded | |
| TR9 6NH | 6 | 6,642 kWh | under 5 | |
| TR9 6LL | 9 | 2,419 kWh | under 5 | |
| TR9 6NQ | 28 | 4,287 kWh | 7 | 10,053 kWh |
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 TR9.
Council tax
What each band costs in Cornwall in 2026-27: Band D £2,591 a year on average, including the police, fire and any county and parish charges.

Energy projects nearby
3 energy projects near the street's postcodes, 1 of them not yet operating.
| Project | Kind | Size | Stage | Distance |
|---|---|---|---|---|
| Burthy Row Farm, Trefullock Moor - Solar Farm & Battery Storage Cornwall PA23/01893 | Solar farm | 49.9 MW | Planning application made Mar 2023 | 1.5 km (0.9 miles) |

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.
Roadworks
No street works under way, planned or finished in the last three months on this street, in permits up to 31 October 2026.
Flood risk
Rivers, the sea or surface water: in this street's postcodes, 1 address is in areas at high risk, 0 at medium risk and 3 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 |
|---|---|---|---|
| TR9 6LG | not in 2 or 3 | 1 / 0 / 0 | unlikely |
| TR9 6NH | not in 2 or 3 | 0 / 0 / 0 | unlikely |
| TR9 6NJ | not in 2 or 3 | 0 / 0 / 0 | unlikely |
| TR9 6LL | not in 2 or 3 | 0 / 0 / 0 | unlikely |
| TR9 6NQ | not in 2 or 3 | 0 / 0 / 3 | 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
2 storm overflows within 1 km (0.6 miles) of the street's postcodes spilled 84 times, for 39 hours in all, in 2025. They discharge into River Gannel(S), Trib of River Gannel.
| Overflow | Into | Spills | Hours | Distance |
|---|---|---|---|---|
| Fraddon Junction Cso South West Water | River Gannel(S) | 23 | 9 | 330 m |
| Queen and Railway Inn Cso South West Water | Trib of River Gannel | 61 | 30 | 950 m (0.6 miles) |
A storm overflow lets sewage diluted with rainwater into a river, stream or the sea when heavy rain overwhelms the sewers, so the spills here affect the water they run into, not homes. A spill is counted the regulators' way: a first 12 hours, then each 24 hours it goes on.
Coal mining
No postcode centre on the street is in a coalfield: the Mining Remediation Authority records no coal mining risk here.
Radon
The highest radon potential in the 1 km squares around the street's postcodes is 10 to 30%: up to that share of homes there is estimated to be at or above the Action Level of 200 becquerels per cubic metre. At least part of that area is a radon Affected Area, where 1% or more of homes are.
Radon is a natural radioactive gas from the ground that can build up indoors; long exposure raises the risk of lung cancer. A three-month test with two small detectors is the only way to know a home's level, and a high level can usually be brought down with a sump or better ventilation. Homes built here in recent decades should have radon protection under the building regulations (basic protection from 3%, full protection from 10%). UKHSA sells a radon report for a single address from its detailed map at ukradon.org.
Historic landfill
No historic landfill site is within 500 m (0.3 miles) of the street's postcodes.
Height above sea level
The street's 43 addresses are between 166 m and 182 m above sea level (174 m on average); the ground rises about 16 m from the lowest to the highest.

Nearest schools
| School | Phase | Ages | Distance | Inspection | Exam results |
|---|---|---|---|---|---|
| Indian Queens Primary School | Primary | 2–11 | 370 m | No overall grade (Jan 2025, graded inspection without an overall judgement): Quality of education: Good; Behaviour and attitudes: Good; Personal development: Good; Leadership and management: Good | 39% at the expected standard in reading, writing and maths, 9% at the higher standard (2025; 50% in 2024 and 40% 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
2 nurseries, pre-schools and clubs within 1.5 km (0.9 miles), the nearest 410 m (0.3 miles) from the middle of the street.

Ofsted also registers 158 childminders and 20 home childcarers (nannies) in Cornwall. It does not publish their addresses, so they cannot be shown here; the council's family information service lists those taking children.

Road safety
No collisions in which someone was hurt were reported on and around the street in 2021 to 2025.
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.

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.
How each figure on this page is matched to the street and worked out: methodology.
