Why poultry shed solar makes economic sense around Cardiff
Cardiff sits at the heart of Carmarthenshire dairy (7% of UK milk), Brecon Beacons upland sheep, Vale of Glamorgan mixed arable. The region's working farms — many tenanted from institutional landlords like Welsh Government rural estate plus National Trust Wales — typically run multi-building holdings with significant on-farm electrical demand. Poultry Shed installations near Cardiff benefit from year-round daytime baseload that aligns well with PV generation: Free-range egg and broiler operations have huge clear-span roofs (typically 80m × 20m per shed). For a typical poultry shed in the Cardiff area in 2026, expect a system in the 50–300 kW range, project value £45,000–£270,000, and simple payback of 5.5 years — pulled to roughly 4.0–5.0 years after 100% Annual Investment Allowance tax relief for incorporated farms.
Typical poultry shed install specification for the Cardiff region
A representative poultry shed install for a working farm near Cardiff delivers around 50 kW of capacity across roughly 300 square metres of roof area. The system would generate approximately 45k kWh per year and offset 10 tonnes of CO2 annually. Biosecurity (Avian Influenza Order 2006, Salmonella National Control Programme) strictly observed during install — restricted access, boot dips, disinfection. RSPCA Assured and Lion Quality schemes increasingly require Scope 2 disclosure from producers.

Cardiff-area planning and grid context
Poultry Shed solar installations near Cardiff typically fall under Class A Part 14 GPDO 2015 Permitted Development — no formal planning permission is required for rooftop PV on agricultural buildings. Cardiff Council planning officers handle any required pre-application consultations efficiently, particularly for buildings outside Conservation Areas and AONBs. Grid connection is via Western Power Distribution, with G99 study timelines of 65–90 working days and full connection windows of 6–14 months on most rural feeders around Cardiff. A good installer submits the G99 application straight after the structural survey; on export-constrained sites the alternative is a no-export self-consumption design, which can connect in 6–8 weeks.
Poultry Shed solar in Cardiff — key features
- Free-range egg and broiler operations have huge clear-span roofs (typically 80m × 20m per shed)
- Continuous ventilation, heating in winter, and lighting create year-round baseload
- Multi-shed sites can support 500+ kW aggregated installs
- Free-range scheme alignment with sustainability evidence
Combined re-roof and PV for older Cardiff-area poultry shed buildings
Many poultry shed buildings around Cardiff pre-date 2000 and carry asbestos cement roof cladding. Under Control of Asbestos Regulations 2012, asbestos cement cannot be retrofitted with PV. The right move is a combined re-roof + PV project: asbestos cement removal by trained operatives (£30–£50/sqm), profiled steel re-cladding (£45–£80/sqm), then PV install on the new roof.
How a competent installer delivers poultry shed solar in Cardiff
Every project starts with a free desk-based feasibility study. Send us your half-hourly meter data and building dimensions (or aerial drone images), and we share an indicative system size, generation forecast, self-consumption ratio, and 25-year financial model within 7 working days. If the numbers work, the installer’s engineers visit the Cardiff-area farm for a one-day structural and electrical survey. You should then receive a fixed-price proposal with full PVSyst yield modelling and DCF financial model. From contract, typical timeline is 4–7 months for rooftop installs and 6–9 months for combined re-roof + PV. We schedule physical works around the farming calendar — calving, lambing, harvest, and shift patterns specific to your operation.

Frequently asked questions
How much does a poultry shed solar install cost in Cardiff?
A typical poultry shed install in Cardiff ranges from £45,000–£270,000, depending on roof area, electrical capacity and whether re-roofing is required first. Cost per kW: £800–£1,000 for sub-100 kW, £750–£900 for 100–250 kW, £700–£850 for above 250 kW. Your installer provides a fixed-price proposal within 7 working days of receiving your half-hourly meter data.
How long does a poultry shed install take in Cardiff?
From contract to commissioning, typically 4–7 months for a rooftop install — including the 6–14 month G99 grid connection process from Western Power Distribution, which runs in parallel. Combined re-roof + PV adds 1–3 months. Physical install work on a single building is 1–4 weeks scheduled around your farming calendar (calving, lambing, harvest).
What grants are available for Cardiff-area farm solar?
100% Annual Investment Allowance (universal, up to 25% effective tax saving year one), Smart Export Guarantee income on surplus units (flat tariffs roughly 4–12p/kWh as at July 2026), Sustainable Farming Incentive land-management actions (not solar) for biodiversity-paired installs. England capital grant rounds (Farming Investment Fund) open and close in short windows; the Improving Farm Productivity round that funded rooftop solar at 25% has closed and no replacement was open in September 2026 — check the gov.uk funding-for-farmers page. Welsh and Scottish farms have additional devolved schemes.
Do I need planning permission for poultry shed solar in Cardiff?
Most rooftop installs on agricultural buildings near Cardiff fall under Class A Part 14 GPDO 2015 Permitted Development — no planning permission required. Listed buildings, AONB designations, and ground-mount above 9m × 9m × 4m height need full planning. Cardiff Council planning officers are familiar with farm-building PV — any consultation should be handled inside the project scope.
Can we install solar on asbestos cement roofs near Cardiff?
Not directly — installers will not normally fix PV through asbestos cement sheets, so the roof is removed or over-clad first. Most asbestos cement work is non-licensed under the Control of Asbestos Regulations 2012, but it needs trained operatives, intact double-wrapped sheets and a licensed disposal site. The standard solution is a combined re-roof + PV project, where the PV business case routinely pays for 60–100% of the re-roof over the 25-year system life.
How long does a G99 grid connection take from Western Power Distribution?
Western Power Distribution typically quotes 65–90 working days for the technical study, with full connection timelines of 6–14 months on most rural feeders (up to 18 months on capacity-constrained networks). A good installer submits the G99 application straight after the structural survey. On export-constrained sites the alternative is a no-export self-consumption design that complete in 6–8 weeks instead.
