Prices in Cardiff Bay have shown modest growth, a year-on-year change of +0.9%. Within Cardiff, Cardiff Bay ranks 2nd by price out of 6 principal towns, and 2nd by transaction volume.

Cardiff Bay shares a HM Land Registry reporting district with neighbouring towns, and the source data does not distinguish Cardiff Bay-specific sales from the wider district. The figures above reflect the whole shared district rather than Cardiff Bay alone.

Cardiff Council, the local planning authority covering Cardiff Bay, approved 511 residential planning applications and refused 53 in the last 12 months, with 206 still awaiting a decision. That is an approval rate of 91%.

Those applications propose around 1,099 homes, an estimated £270.7m of development value at local sale prices. Treat the unit total as an upper bound, since an outline permission and its reserved-matters application both count.

Cardiff Council covers more than one town in Cardiff, so these figures are authority-wide rather than specific to Cardiff Bay alone.
