Southport roofs in numbers
The figures behind the guide: what kind of houses Southport has, how old they are, how efficient, who owns them, and how many already have panels. Every number comes from an official source, read on 3 November 2026.
Figures checked at source on 3 November 2026. Written by SEO Dons, who neither sell nor fit solar panels.
The houses
The Census does not publish tables for the Southport built-up area, so these figures are for the Southport parliamentary constituency on its 2010 boundary: the seven Sefton wards of Ainsdale, Birkdale, Cambridge, Dukes, Kew, Meols and Norwood.
| Type | Southport | Sefton |
|---|---|---|
| Semi-detached | 47.5% | 46.1% |
| Detached | 19.3% | 16.2% |
| Terraced | 6.5% | 18.4% |
| Purpose-built flat | 16.6% | 13.6% |
| Flat in a converted or shared house | 7.7% | 4.2% |
| Other converted building or commercial building | 2.3% | 1.6% |

Who owns them
40.2% of Southport households own their home outright and 27.5% with a mortgage, so roughly two in three can decide on solar for themselves. 23.6% rent privately, more than Sefton's 18.2%, and need a landlord's agreement. Only 7.6% rent from a council or housing association. With 25.6% of residents aged 65 or over, Southport is an older town than Sefton as a whole (23.2%), which matters for solar because people at home in the day use more of their panels' output.
How old they are
Council tax records count 132,270 dwellings in Sefton. 27.5% were built before 1919, against 20.4% across England and Wales, and 47.4% before 1945; only 9.6% are from 2000 or later. Bungalows are 6.8% of the stock (England and Wales 9.1%) and flats and maisonettes 20.8%. The figures are for Sefton as a whole; council tax build periods are not published for Southport alone.
How efficient they are
48.94% of Sefton's homes have an EPC of C or better, below England's 53.28%, and the median score is 68 against England's 69. Among homes built before 1929, only 29.72% reach C, with a median of 63. In the Southport constituency on its current boundary, 48.09% reach C. Homes rated D or below are the ones the Warm Homes: Local Grant is for; see grants.

Our calculation from DESNZ's renewable electricity by local authority (installations and household estimates, end of 2025).
Sefton had 3,964 solar installations of all sizes at the end of 2025, with 19.02 MW of capacity, up from 3,272 a year earlier: growth of 21%. Even so, it has the fewest per household of the five Merseyside boroughs. DESNZ's constituency figures put home installations in the Southport seat (current boundary) at 1,599, totalling 7.248 MW, at September 2026: about 3.4 for every 100 dwellings. Nationally, new home systems installed in September 2026 averaged about 5.7 kW each, more than our hipped semi example can take.
