Gas and electricity use

| Postcode | Electricity meters | Typical electricity | Gas meters | Typical gas |
|---|---|---|---|---|

| TR21 0LP | 43 18 Economy 7 | 2,444 kWh | none recorded |
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 TR21.

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, 40 addresses are in areas at high risk, 2 at medium risk and 18 at low risk. Each address counts once, at the higher of its rivers-and-sea and surface-water risk.
Rivers and the sea alone: of the 55 homes the Environment Agency counts, 30 are in areas at high risk, 5 medium, 2 low and 7 very low.
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: at least one postcode centre is in flood zone 3. Zone 3 is a 1% (1 in 100) or greater annual chance of flooding from rivers, or 0.5% from the sea, ignoring defences.
| Postcode | Planning zone | Addresses at high / medium / low risk | Groundwater |
|---|---|---|---|
| TR21 0LN | zone 3 | 21 / 1 / 3 | unlikely |
| TR21 0LP | not in 2 or 3 | 19 / 1 / 15 | 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
Part of the street is in land the coast is projected to erode by 2105, with the shoreline management plan carried out. Lenders and insurers may decline homes in an erosion zone, and no compensation is paid for land lost to the sea.
| Projection | Policy for the frontage | Erosion | Distance |
|---|---|---|---|
| By 2055, with the shoreline management plan carried out | Hold the line Rame Head to Hartland Point | none (the line is held) | 0 m |
| By 2105, with the shoreline management plan carried out | Managed realignment Rame Head to Hartland Point | up to 21 m | Inside it |
| By 2105, if defences are not maintained or built | No intervention Rame Head to Hartland Point | up to 21 m | Inside it |
Each shoreline management plan sets a policy for each stretch of coast: hold the line (keep defences where they are), managed realignment (let the shore move back in a controlled way), advance the line, or no active intervention. Erosion is the distance the shore may move back, counted from today, for the higher central climate change allowance. The maps are guidance from national modelling, not a survey of any one home; the council's coastal team can say more.
Storm overflows
1 storm overflow within 1 km (0.6 miles) of the street's postcodes spilled 60 times, for 52 hours in all, in 2025. They discharge into Atlantic Ocean.
| Overflow | Into | Spills | Hours | Distance |
|---|---|---|---|---|
| Cso at Atlantic Hotel South West Water | Atlantic Ocean | 60 | 52 | 120 m |
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 30% or more: 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 53 addresses are between 2 m and 5 m above sea level (4 m on average).

Nearest schools
| School | Phase | Ages | Distance | Inspection | Exam results |
|---|---|---|---|---|---|
| The Five Islands Academy Church of England | All-through | 3–16 | 760 m (0.5 miles) | Good (Oct 2023, overall grade under the previous framework) | 57% at the expected standard in reading, writing and maths, 7% at the higher standard (2025; 57% in 2024 and 37% in 2023) GCSE 2026 (provisional): Attainment 8 53.2 (48.7 in 2025 and 52.8 in 2024); 38.9% grade 5+ in English and maths |
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.

Traffic on nearby roads
The busiest counted road within 500 m (0.3 miles) is the A3111 between A3112 and A3110, with 1,406 motor vehicles a day on average in 2025, 480 m (0.3 miles) from the street's postcodes.
| Road | Between | Vehicles a day | Lorries | Ten years before | Distance |
|---|---|---|---|---|---|
| A3111 | Pierhead, Hugh Town to A3112 | 957 estimated; counted 2020 | 2% | -12% since 2015 | 160 m |
| A3111 | A3112 to A3110 | 1,406 estimated; counted 2024 | 3% | -5% since 2015 | 480 m (0.3 miles) |
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.

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.
