Southampton specifics

Housing: Georgian and Victorian housing in the Old Town and Portswood mixes with 1960s tower blocks; maritime heritage influences design codes.

Climate: Solent exposure brings salt air and higher wind loads; coastal-facing elevations need robust hardware and marine-treated frames.

Price driver: South-east cost base pushes labour 10-15% above Midlands; port logistics keep material supply steady.

Installers: Dense installer coverage across Hampshire; quick access to Portsmouth and Bournemouth expands competition.
