Flood risk in Ireland

Flood maps and flood risk in Ireland, by county and town

The OPW keeps two things: a register of past floods and a set of modelled flood maps (CFRAM) for about 300 communities. We counted both around every town with at least 100 sales since 2010: 959 of 1,069 towns have at least one recorded flood within 2 km of the centre. Pick a county, then a town, then check the exact Eircode.

Figures compiled from the public records listed at the foot of this page. Data snapshot: . Updated when the records change.

Check one house in Ireland

959 of 1,069 Irish towns have a recorded flood within 2 km of the centre.

One specific house in Ireland: flood zone for that Eircode, recorded floods within 500 m, radon, planning applications within 300 m, BER, sale history. Thirty-eight checks in all, each linked to the public record.

Check a flood zone by address

The county and town pages below give the odds for an area. For one house, type the Eircode into the box above: the report puts the point against the OPW river and coastal extents and the past flood register; the free snapshot shows how many checks flag up. If it does, get an insurance quote before you go sale agreed. A flood exclusion is a problem your bank will notice at drawdown.

GuideIs my house in a flood zone? What the OPW maps say and what insurers do with them

Questions people ask

How do I check if an address is in a flood zone?
Open the OPW flood maps on floodinfo.ie, search the address, and turn on the river and coastal extent layers and the past flood events layer. Look at the plot itself, not the town: two houses on one road can sit either side of an extent line. The free snapshot on this site does that lookup for one Eircode and flags the result; the full report lists every recorded flood within 500 m with dates and OPW notes.
Are these figures about my house?
No. They describe the town or county. The same public sources, read for one Eircode, are what the report does. The free snapshot shows how many checks flag for a specific address; the report says which.
How current are they?
Compiled from the live public sources when this page was built, and rebuilt with each site update. Each page names its source with a link.
