The question
To ask the Scottish Government whether it will confirm the total number of existing (a) residential, (b) commercial and (c) industrial properties that are considered at risk of flooding, based on SEPA's use of the Representative Concentration Pathway 8.5 emissions scenario, broken down by local authority area.
The answer
SEPA recently completed an update to their National Flood Risk Assessment. This was summarised in their December 2025 National Flood Risk Assessment 2025 report.The report includes data on the number of properties at risk in a medium risk current day scenario* and the number of properties at risk in 2100 under a medium risk climate change scenario**. These are broken down by local authority and residential/non residential properties in Table B, rather than split by property type. Local authority distribution of flood risk in the appendix of the report. A subset of relevant data from that table is replicated below.SEPA plan to publish more detailed data in March 2026.Local AuthorityTotal Properties at RiskResidentialNon-Residential% of Total Properties at RiskProperties at Risk by 2100Aberdeen City204001820022001531400Aberdeenshire198001300068001129100Angus660043002300911500Argyll & Bute12200820040001817700City of Edinburgh391003650026001464500Clackmannanshire51004500600187500Comhairle nan Eilean Siar1700130050093100Dumfries & Galloway195001160079001727200Dundee City8600740013001013900East Ayrshire8300640019001212500East Dunbartonshire57005000700118800East Lothian7800620016001212400East Renfrewshire46004200400106700Falkirk10000780022001218900Fife18700148003900929500Glasgow City529004910038001582000Highland206001360071001237000Inverclyde630055008001510200Midlothian4300360070097200Moray7900480032001313600North Ayrshire8700710016001014700North Lanarkshire189001650023001130100Orkney22001500800133500Perth & Kinross12700840043001320800Renfrewshire116001040012001219100Scottish Borders14700950052001720200Shetland110060050071700South Ayrshire7000520019001012300South Lanarkshire186001540032001029100Stirling7500560019001412900West Dunbartonshire8400730011001711900West Lothian780065001300813400
* defined as areas with more than 0.5% chance of flooding each year** The climate change scenario is based on SEPA's future flood maps which use a variety of climate change scenarios including the Representative Concentration Pathway 8.5 emissions scenario (UKCP18) and scenarios from UKCP09. More details about SEPA's future flood maps and the scenarios used can be found in National Flood Risk Assessment 2025 and future-flood-maps-summary_v4.pdf.
