Facts from official records at sample postcodes, not a rating of Wrexham or of any home.
Flooding from rivers and the sea
We checked each postcode centre against Natural Resources Wales' Flood Map for Planning.
1 of the 9 postcodes we checked is in a mapped flood area:
- LL13 7RF: Flood Zone 3
A home in a mapped flood area can cost more to insure, and some lenders ask more questions. Ask the seller about past flooding and any flood claims, and ask your solicitor for an environmental search.
Surface water flooding
Flooding from heavy rain that can't drain away fast enough. It can happen far from any river.
- Very low: 9 of 9 postcodes
Surface water risk changes over a few metres, with the lie of the land. Medium means a 1% to 3.3% chance of flooding each year, and high more than that. Ask the seller about past flooding and look at the drainage when you view.
Radon
Radon is a natural radioactive gas from the ground. The UK Health Security Agency maps the share of homes above its action level in each 1 km square.
At all 9 postcodes we checked, parts of the surrounding square are a radon Affected Area. The highest is up to 10–30% of homes above the action level.
The map shows the highest value in each square, not a measurement for any home. A three-month radon test, or an address report from UKradon, tells you about a particular house. Where levels are high, a sump or better ventilation usually brings them down.
Ground stability
The British Geological Survey rates natural ground hazards, such as clay that shrinks and swells, and old non-coal mine workings.
- Landslides: moderate near 3 of the 9 postcodes we checked
Non-coal mining hazard is moderate or significant at 2 of the 9 postcodes we checked.
Ratings are for the surrounding area, not for a particular plot. Where clay shrink-swell or old workings are recorded, ask your surveyor to look for cracking and movement, and ask the seller about subsidence claims. A level 2 or level 3 survey is worth more here than a valuation alone.
Old landfill sites
We don't include old landfill records for Wales yet.
Your solicitor's environmental search covers old landfill near the address you're buying in Wrexham.
Conservation areas and listed buildings
Whether each postcode centre falls in a conservation area, on a listed building's site, or under similar protections.
None of the 9 postcode centres we checked falls in a conservation area or on a listed building's site. Older streets and town centres often do, so check the address.
In a conservation area or a listed building you need consent for many changes, such as new windows, extensions or taking down trees. Check before you plan work.
House prices
The average price in Wrexham was £212,778 in July 2026, up 2.2% on a year earlier. This covers every home in the council area, so a particular street can be well above or below it.
At the postcodes we checked, Land Registry has 5 sales in the last 3 years, with a median of £275,000 and a range of £130,000 to £600,000. A handful of postcodes is a small sample, so treat this as a rough guide.
Our postcode check lists recent sales on the street, which tell you more about a particular home than a town average.
Crime
Measured around LL13 8AE, near the centre of Wrexham.
647 crimes were reported within about a mile of the centre in August 2026. Town centres usually have more, because of shops and nightlife.
- Violence and sexual offences228
- Anti-social behaviour118
- Shoplifting102
- Criminal damage and arson52
- Other theft48
- Public order44
Our postcode check shows crime around any postcode, so you can see the street you're looking at.
