Serving Swansea
Swansea is our home city and the base from which every FLD project is run. With a population of 251,304 at the 2021 census, it is the second city of Wales and the administrative seat of the City and County of Swansea. The local economy pivots around Swansea University, Morriston Hospital under Swansea Bay UHB, Admiral, the DVLA headquarters in Morriston, the City Council itself and Swansea City AFC.
The city carries one of the most dramatic industrial heritages in the United Kingdom. Nineteenth-century Swansea was known as Copperopolis, smelting over half of the world's copper at its peak, and the Lower Swansea Valley spent the twentieth century as the largest area of industrial dereliction in Europe before its phased reclamation. That legacy still shapes the commercial rooftop stock available today, concentrated at SA1 Waterfront, Swansea Enterprise Park in SA6 8QR, the Kingsway Innovation Corridor and Parc Tawe.
For domestic solar, the housing mix across the SA1 postcode ranges from Victorian maritime terraces through interwar semi-detached into the new marina-side apartments of Copr Bay. Landmarks include Swansea Marina, the Dylan Thomas Centre, Wind Street, the Swansea Arena which opened in 2022, and the rugby heritage that sits adjacent to Principality elsewhere in the region.
Regeneration activity remains intense through 2024 to 2026. Copr Bay Phase 2 is driving further city-centre redevelopment, the Kingsway is subject to district heat-network proposals, and the Swansea University Bay Campus continues its expansion programme. Each of those schemes produces exactly the kind of large, south-facing or flat rooftop that commercial solar thrives on.
At 950 kWh/kWp per year according to PVGIS irradiation data, Swansea delivers the baseline South Wales yield. That translates to a 100 kWp commercial system generating 95,000 kWh annually, with year-one benefit of approximately £24,000 at prevailing commercial tariffs and a simple payback around 3.5 years, dropping closer to 2.6 years once Annual Investment Allowance full-expensing is applied.
We have worked in every corner of the city, from the sea front through the Uplands and across the valley. Swansea is where our directly-employed engineers live, which means response times on the core service here are measured in hours rather than days.
