Serving Morriston

Morriston occupies the SA6 postcode on the north-eastern shoulder of Swansea and is arguably the most commercially dense target area in the whole of West Wales. Ward population is around 20,000 and the wider SA6 postcode carries approximately 34,000 residents, but the defining feature is the concentration of large employers.

Morriston Hospital is the flagship tertiary centre for Swansea Bay University Health Board. It hosts the regional burns unit and the cardiology centre, both of which drive continuous-demand electrical loads that make on-site generation economically and operationally attractive. The DVLA has its national headquarters on Morriston Hill, and Admiral Swansea operates a major office presence across Swansea Enterprise Park.

Swansea Enterprise Park at SA6 8QR is the single densest commercial rooftop cluster in West Wales. Around 5,000 staff work across financial services, logistics and manufacturing inside that estate, with further commercial estate running through Plasmarl, Llansamlet Industrial Estate and out to Fforestfach. For a Swansea-based solar and electrical contractor like FLD, the estate is a target-rich environment for 100 kWp to 500 kWp commercial rooftop PV installations, with installer drive-time measured in minutes.

Cultural landmarks include the Tabernacle, often described as the Cathedral of Welsh Nonconformity and dating from 1872, and the Swansea.com Stadium which hosts Swansea City AFC and the Ospreys rugby region.

Redevelopment activity across 2024 to 2026 includes the second phase of Swansea Central and the Kingsway Innovation Corridor tenant recruitment drive, which is pulling further spillover demand into Swansea Enterprise Park as overspill tenants look for Grade-B commercial space at accessible rents.

At the standard Swansea yield of 950 kWh/kWp annually, a 250 kWp commercial system generates 237,500 kWh, with first-year benefit at 27p/kWh blended of around £65,000 and simple payback of 4.1 years. Under AIA full-expensing that drops to approximately 3.0 years post-tax.

If a South Wales commercial solar programme looks for a single concentrated territory for pipeline build, SA6 is it.

FAQ

FAQs for Morriston

At 30p/kWh grid electricity, a 100 kWp system generating 95,000 kWh/yr with 70% self-consumption delivers around £24,000 of year-one benefit against c. £85,000 capex, a 3.5-year simple payback. Under Annual Investment Allowance first-year 100% relief, post-tax payback is closer to 2.6 years. South Wales yields 940 to 985 kWh/kWp/year depending on postcode, comfortably enough for commercial solar to be cashflow positive from month one with a PPA.
A Power Purchase Agreement is a financing arrangement where we fund and install a rooftop solar system at no upfront cost. Your business buys the electricity the system generates at a fixed, RPI-indexed rate that is lower than your grid tariff. The PPA typically runs 10 to 25 years. At the end you can extend, buy out at a pre-agreed residual value, or have the system removed. It suits businesses that want immediate savings without capital outlay and that are credit-worthy with a stable site.
Once DNO G99 connection approval is in place and materials are on site, a typical 100 kWp rooftop install takes 5 to 8 working days. The critical-path item is usually the NGED Type A connection approval, which is 3 to 6 months in South Wales in 2026. We manage that application as part of our scope.
G99 is the Engineering Recommendation governing how generation equipment connects to the UK distribution network. For commercial solar above 16 A per phase, you need G99 approval from your District Network Operator before export. In South Wales that is National Grid Electricity Distribution (NGED, formerly Western Power Distribution). Type A connections are the standard sub-1 MW route, typically 3 to 6 months in 2026.
