Why pig unit solar makes economic sense around Leeds
Leeds sits at the heart of East Riding's largest-scale arable holdings, Yorkshire Dales upland sheep and beef, intensive pig and poultry across the wider region. The region's working farms — many tenanted from institutional landlords like Harewood Estate and Bolton Abbey (Devonshire) — typically run multi-building holdings with significant on-farm electrical demand. Pig Unit installations near Leeds benefit from year-round daytime baseload that aligns well with PV generation: Climate-controlled finisher houses have high year-round ventilation and heating loads. For a typical pig unit in the Leeds area in 2026, expect a system in the 40–250 kW range, project value £36,000–£225,000, and simple payback of 6 years — pulled to roughly 4.5–5.5 years after 100% Annual Investment Allowance tax relief for incorporated farms.
Typical pig unit install specification for the Leeds region
A representative pig unit install for a working farm near Leeds delivers around 40 kW of capacity across roughly 240 square metres of roof area. The system would generate approximately 36k kWh per year and offset 8 tonnes of CO2 annually. African Swine Fever biosecurity (Pig Health Scheme) strictly observed during install. NVZ (Nitrate Vulnerable Zone) slurry-management compliance unaffected. AHDB pork sustainability framework increasingly references on-farm renewables.

Leeds-area planning and grid context
Pig Unit solar installations near Leeds typically fall under Class A Part 14 GPDO 2015 Permitted Development — no formal planning permission is required for rooftop PV on agricultural buildings. Leeds City Council planning officers handle any required pre-application consultations efficiently, particularly for buildings outside Conservation Areas and AONBs. Grid connection is via Northern Powergrid, with G99 study timelines of 65–90 working days and full connection windows of 6–14 months on most rural feeders around Leeds. We submit G99 applications immediately after structural survey to start the clock; for export-constrained sites we design "no-export" self-consumption systems that connect in 6–8 weeks.
Pig Unit solar in Leeds — key features
- Climate-controlled finisher houses have high year-round ventilation and heating loads
- Farrowing-house heat lamps and creep heaters major winter loads
- Often paired with biogas/AD on intensive sites — PV complements rather than competes
- Red Tractor Pork and RSPCA Assured scheme alignment
Combined re-roof and PV for older Leeds-area pig unit buildings
Many pig unit buildings around Leeds 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: HSE-licensed asbestos removal (£30–£50/sqm), profiled steel re-cladding (£45–£80/sqm), then PV install on the new roof. We've delivered combined re-roof + PV across Yorkshire on pig unit buildings, with the PV business case routinely paying for 60–100% of the re-roof cost over the 25-year system life.
How we deliver pig unit solar in Leeds
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, our engineers visit the Leeds-area farm for a one-day structural and electrical survey. We deliver 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 pig unit solar install cost in Leeds?
A typical pig unit install in Leeds ranges from £36,000–£225,000, 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. We provide a fixed-price proposal within 7 working days of receiving your half-hourly meter data.
How long does a pig unit install take in Leeds?
From contract to commissioning, typically 4–7 months for a rooftop install — including the 6–14 month G99 grid connection process from Northern Powergrid, 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 Leeds-area farm solar?
100% Annual Investment Allowance (universal, up to 25% effective tax saving year one), Smart Export Guarantee at 8–15p/kWh on surplus, Sustainable Farming Incentive 2025 actions for biodiversity-paired installs. Farming Investment Fund grants are sometimes available when solar is paired with other capital items (robotic milking, grain dryers). Welsh and Scottish farms have additional devolved schemes.
Do I need planning permission for pig unit solar in Leeds?
Most rooftop installs on agricultural buildings near Leeds 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. Leeds City Council planning officers are familiar with farm-building PV — we handle any consultation as part of the project.
Can we install solar on asbestos cement roofs near Leeds?
No — asbestos cement must be removed by HSE-licensed contractors first under Control of Asbestos Regulations 2012. 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. We deliver this routinely across Yorkshire.
How long does a G99 grid connection take from Northern Powergrid?
Northern Powergrid 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). We submit G99 immediately after structural survey to start the clock. For export-constrained sites we design "no-export" systems sized for self-consumption that complete in 6–8 weeks instead.
