Serving Builth Wells

Builth Wells -- Llanfair-ym-Muallt in Welsh -- is a spa town on the River Wye in mid-Powys, population approximately 2,600, and the home of the Royal Welsh Agricultural Show, the largest agricultural show in Europe. The Show draws 200,000-plus visitors over four days each July to the permanent Royal Welsh Showground on the eastern edge of the town, making Builth Wells a genuinely national venue despite its modest permanent population.

Powys County Council administers the area. The Royal Welsh Showground is the defining commercial feature of Builth Wells from a solar perspective. The showground estate covers approximately 130 acres and carries permanent buildings -- livestock halls, agricultural machinery halls, catering and hospitality pavilions, administrative blocks and grandstands -- that represent one of the largest single-site commercial solar opportunities in mid-Wales. The Show Society operates the site year-round for events, training and agricultural society activities, maintaining consistent electricity demand outside the July peak.

The wider Builth economy is centred on service provision to the surrounding hill-farming community, the spa town heritage (the mineral wells gave the town its name), and the Wye valley tourism corridor that runs south toward Hay-on-Wye. The Wyeside Arts Centre is the primary cultural venue, and the Wye Valley Walk passes through the town.

Housing in Builth Wells is predominantly Victorian and Edwardian -- the spa era left a legacy of substantial villa-style properties on the higher ground above the Wye, alongside the more typical terrace and semi stock in the town centre. Villa properties here have particularly good south-facing roof planes for domestic solar.

The Bannau Brycheiniog National Park southern boundary runs approximately 8 miles to the south of Builth Wells. The town itself is outside the Park, which means standard permitted development applies without Park-specific visual-impact requirements. For farm holdings south of the A470 toward the Park boundary, the usual pre-application check confirms the position.

At 945 kWh/kWp, a 150 kWp installation on Royal Welsh Showground permanent buildings generates 141,750 kWh annually. Showground electricity demand runs 11 months of the year for events, agricultural society functions and winter storage, with significant July spike demand. With 65% self-consumption at 26p/kWh average, year-one saving reaches approximately £32,000 on £130,000 capex. Post-AIA payback 3.3 years.

FLD reaches Builth Wells via the A40 and A470 in approximately 88 minutes from Swansea. The town serves as the hub for a Powys central circuit combining with Rhayader and Brecon.

FAQ

FAQs for Builth Wells

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.
Usually yes. Dairy, pig, poultry and grain-drying operations have large daytime loads that match solar output. A 50 kWp farm array generating 47,500 kWh a year, with 75% self-consumption at 28p/kWh plus 25% export at 12p/kWh, delivers first-year benefit of c. £11,400 against capex of c. £45,000. Simple payback 3.9 years, post-tax payback c. 2.9 years with Annual Investment Allowance. Farming Connect grants can shorten this further.
Farming Connect provides capital grants of up to 40% for solar PV installations on agricultural buildings -- farm offices, dairy units, pig and poultry sheds, and machinery stores. Applications require a pre-application consultation with a Farming Connect business development manager and a full business case. FLD coordinates the Farming Connect application alongside the feasibility survey, including the energy audit and business case documentation the scheme requires. Welsh-medium applications are available.
Yes, depending on organisation type. Welsh SMEs and public bodies can access the Welsh Government Energy Service, Ynni Cymru Capital Grants (approximately £10 m in 2026-27, £25,000 to £1 m per project) and Development Bank of Wales Green Business Loans. Welsh public-sector bodies use Salix Wales Funding Programme rather than the English Public Sector Decarbonisation Scheme. Farms may be eligible under Farming Connect. Always check current-year terms before committing.
Yes, with sensitivities. The Bannau Brycheiniog National Park (renamed from Brecon Beacons in April 2023) includes a Dark Sky Reserve and has a net-zero management plan. Rooftop solar on non-listed buildings is generally permitted development under Welsh planning rules, though the Park authority treats listed structures and archaeologically-sensitive farmsteads on a case-by-case basis. We have delivered farm and hospitality solar inside the Park boundary.
