Bellsoph rental valuations are automated estimates based on advertised rental evidence and official statistics.

Portsmouth sits below the South East average
In September 2026, Portsmouth’s average rent was £1,374. ONS private rental price statistics cover new and existing tenancies; this area average is statistical context, not an advertised rent or an individual property comparable.
The Portsmouth average was 4.5% lower the South East England average of £1,438. Portsmouth’s annual rent rate was 0.6 percentage points lower the regional rate.
Bedroom-count averages for a closer benchmark
For September 2026, the average was £903 for one bed homes, £1,139 for two bed, £1,366 for three bed and £1,968 for four or more bed. These category averages can help frame a rent comparison by size, but they are not listings or like-for-like comparables.
Annual rent rates differed across the size bands: 3.5% for three bed homes and 2.6% for four or more bed homes, a published gap of 0.9 percentage points. Match the relevant size band where possible, while treating the figures as area-level context.
