Gas and electricity use
Homes with gas used 13,463 kWh of it on average in 2024, 29% more than the district's 10,456 kWh, and 3,074 kWh of electricity, 8% more than the district's 2,838 kWh. There are gas meters for about 100% of the homes.
These are all the homes on the 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 LL30.
Council tax
What each band costs in Conwy in 2026-27: Band D £2,473 a year on average, including the police and community council charges.
| A | B | C | D | E | F | G | H | I |
|---|---|---|---|---|---|---|---|---|
| £1,649 | £1,923 | £2,198 | £2,473 | £3,022 | £3,572 | £4,121 | £4,946 | £5,770 |
Homes by band in the neighbourhood around this street: most are in band E (39% of about 840 homes).
Planning and heritage
- Conservation area: no postcode centre in this street's postcodes is in one.
- Listed buildings on or by this street: none.
- Article 4 directions, tree preservation orders and green belt: Wales has no national record of these; the council's planning department holds them.
Energy projects nearby
No wind turbine or waste plant within 5 km (3.1 miles), and no solar farm, battery site or other project of 1 MW or more within 2 km (1.2 miles), of the street's postcodes, operating or planned.
Roadworks
Street works permits come from the Department for Transport's Street Manager, which covers England only.
Flood risk
Rivers, the sea or surface water: of the 47 address points in this street's postcodes, 1 at high risk, 0 at medium risk and 30 at low risk. Each counts once, at the higher of its rivers-and-sea and surface-water risk.
Rivers and the sea alone: 1 at high risk, 0 at medium risk and 30 at low risk. Surface water and small watercourses alone: 1 at high risk, 0 at medium risk and 3 at low risk.
High: 3.3% (1 in 30) or more chance of flooding a year. Medium: 1% to 3.3%. Low: 0.1% to 1%. The map allows for flood defences. Address points are every property record (UPRN) in the postcode, each counted if it is in an area or within 5 m of one (the maps stop at building walls); a few are not homes, such as garages, business units or caravan pitches. Counts cover whole postcodes, which can include other streets.
Flood zone for planning: the 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. Welsh zones include an allowance for climate change.
Recorded floods
No recorded flood covers the centre 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
The nearest projected erosion zone is 140 m from the street's postcodes (by 2105, if defences are not maintained or built).
| Projection | Policy for the frontage | Erosion | Distance |
|---|---|---|---|
| By 2105, if defences are not maintained or built | No intervention SMP22 (Great Orme Head to Solway Firth) | up to 20 - 40 m | 140 m |
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
No storm overflow outlet is within 1 km (0.6 miles) of the street's postcodes in this record, which covers the overflows reported to the Environment Agency: most of Wales's are reported to Natural Resources Wales instead.
Coal mining
No postcode centre here is in a coalfield: the Mining Remediation Authority records no coal mining risk here.
Radon
The postcode is in a 1 km square with radon potential up to 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 the square 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 47 addresses are between 2 m and 8 m above sea level (6 m on average); the ground rises about 6 m from the lowest to the highest.

| Ysgol Bodafon Church in Wales Welsh and English | Primary | 3–11 | 1.9 km (1.2 miles) | Estyn reports · My Local School | Not published in Wales |
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. Wales publishes no school results tables.
Nurseries and childcare
Ofsted registers childcare in England only. In Wales, nurseries, playgroups and childminders are registered and inspected by Care Inspectorate Wales, whose directory of services lists them with their reports.

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.
