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

Swansea Council, the local planning authority covering Mumbles, approved 412 residential planning applications and refused 117 in the last 12 months, with 182 still awaiting a decision. That is an approval rate of 78%.

Those applications propose around 2,092 homes, an estimated £397.6m 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.

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