SA1, Swansea: Mount Pleasant, St Thomas and Townhill

Here you'll find the official figures for SA1, a postcode district in Swansea, gathered in one place: what homes sell for, the homes themselves, schools, crime and the cost of living.

SA1 takes in Mount Pleasant, St Thomas, Townhill and Hafod, with around 23,300 homes in all. Terraced houses are the most common home to change hands here, making up about 55% of sales. Flats come next, at just under a quarter.

Homes in SA1 sold for about £139,000 on average in the five years to August 2026, up 15% on the five years before. Across Swansea as a whole, homes sold for about £190,000 over the same five years, so prices here are lower. Most of the district sits outside mapped flood risk areas.

All figures come from official sources, listed at the bottom of this page.

Of the homes sold in the five years to August 2026, 55% were terraced houses, 23% were flats, 18% were semi-detached houses and 4% were detached houses. 26% were leasehold and 2% were new builds (39 sales).

17 state schools have an SA1 postcode, and 20 more are within a mile of one of its postcodes. Being near a school is not the same as being in its catchment: check admissions with the council.

Estyn, the inspectorate for schools in Wales, stopped giving schools an overall grade from spring 2022, so there is no single rating to show. Each school's inspection reports are on estyn.gov.wales.

We checked the centre of each of SA1's 1,299 postcodes against the flood risk maps from Natural Resources Wales. 1,244 sit outside every mapped area, and 55 are in one: 4 at high risk, 5 at medium risk and 46 at low risk. The centre of a postcode is not each home in it, so check an exact address on NRW's flood risk map.

• High risk from rivers or the sea or surface water and small watercourses: Greater than a 1 in 30 (3.3%) chance of flooding each year.
• Medium risk from the sea: Between a 1 in 200 (0.5%) and a 1 in 30 (3.3%) chance of flooding each year.
• Medium risk from surface water and small watercourses: Between a 1 in 100 (1%) and a 1 in 30 (3.3%) chance of flooding each year.
• Low risk from rivers or surface water and small watercourses: Between a 1 in 1,000 (0.1%) and a 1 in 100 (1%) chance of flooding each year.
• Low risk from the sea: Between a 1 in 1,000 (0.1%) and a 1 in 200 (0.5%) chance of flooding each year.

The sentence above counts each postcode once, at its highest risk. The table counts it under each source, so a postcode at risk from more than one source appears more than once.

NRW's map takes into account the effect of flood defences where it has information on them. Defences reduce the chance of flooding but do not completely stop it, as they can be overtopped or fail.
