CF11, Cardiff: Pontcanna, Grangetown and Riverside

This page brings together the official data on CF11, one of Cardiff's postcode districts, so you can see what homes cost and what the area is like in one place.

Pontcanna, Grangetown, Riverside and Penarth Flats are among the places in CF11, which has around 18,400 homes in all. Of the homes that sold, terraced houses were the most common, at just under half. Flats come next, at about two in five. About two in five homes sold were leasehold.

Homes in CF11 sold for about £235,000 on average in the five years to August 2026, up 27% on the five years before. Across Cardiff as a whole, homes sold for about £262,000 over the same five years, so prices here are lower. Just over four in five of the CF11 postcodes are in a mapped flood risk area, almost all of them at low risk; the flood section below has the detail.

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

Of the homes sold in the five years to August 2026, 48% were terraced houses, 40% were flats, 10% were semi-detached houses and 3% were detached houses. 41% were leasehold and 3% were new builds (65 sales).

11 state schools have a CF11 postcode, and 36 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 CF11's 868 postcodes against the flood risk maps from Natural Resources Wales. 158 sit outside every mapped area, and 710 are in one: 3 at high risk, 1 at medium risk and 706 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: Greater than a 1 in 30 (3.3%) chance of flooding each year.
• Medium risk from rivers: 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.
