Why pig unit solar makes economic sense around Liverpool
Liverpool sits within reach of west Lancashire mossland salad production (UK leek and lettuce centre), Cheshire dairy, Wirral mixed arable. The region's working farms — many tenanted from institutional landlords like Tatton Estate — typically run multi-building holdings with significant on-farm electrical demand. Pig Unit installations benefit from year-round daytime baseload aligned with PV generation: Climate-controlled finisher houses have high year-round ventilation and heating loads. For a typical pig unit in the Liverpool area in 2026, expect a system in the 40–250 kW range, project value £36,000–£225,000, simple payback of 6 years — pulled to 4.5–5.5 years after 100% Annual Investment Allowance for incorporated farms.
Typical pig unit install specification for Liverpool
A representative install for a working farm near Liverpool delivers around 40 kW of capacity across roughly 240 square metres of roof area, generates 36k kWh per year, and offsets 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.

Liverpool-area planning and grid context
Pig Unit solar installations near Liverpool typically fall under Class A Part 14 GPDO 2015 Permitted Development — no formal planning permission required. Liverpool City Council planning officers handle pre-application consultation efficiently for buildings outside Conservation Areas and AONBs. Grid connection is via Scottish Power Energy Networks, with G99 study timelines of 65–90 working days and full connection windows of 6–14 months on most rural feeders. We submit G99 immediately after structural survey; for export-constrained sites we design "no-export" self-consumption systems that connect in 6–8 weeks.
Pig Unit solar in Liverpool — 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 Liverpool-area buildings
Many pig unit buildings around Liverpool 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 deliver combined re-roof + PV across Merseyside / West Lancashire routinely.
How we deliver pig unit solar in Liverpool
Every project starts with free desk-based feasibility. Send us half-hourly meter data and building dimensions; 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 for a one-day structural and electrical survey. Fixed-price proposal with full PVSyst yield modelling and DCF financial model follows. From contract: typical 4–7 months to commissioning for rooftop, 6–9 months for combined re-roof + PV. We schedule works around the farming calendar.

Frequently asked questions
How much does a pig unit solar install cost in Liverpool?
A typical pig unit install in Liverpool ranges from £36,000–£225,000, depending on roof area, electrical capacity and whether re-roofing is required. Cost per kW: £800–£1,000 for sub-100 kW, £750–£900 for 100–250 kW, £700–£850 for above 250 kW. Fixed-price proposal within 7 working days of receiving your half-hourly meter data.
How long does a pig unit install take in Liverpool?
From contract to commissioning: typically 4–7 months for a rooftop install. Includes the 6–14 month G99 grid connection from Scottish Power Energy Networks running in parallel. Combined re-roof + PV adds 1–3 months. Physical install on a single building is 1–4 weeks scheduled around the farming calendar.
What grants are available for Liverpool-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, Farming Investment Fund grants when paired with eligible items. Welsh and Scottish farms have additional devolved schemes.
Do I need planning permission for pig unit solar in Liverpool?
Most rooftop installs near Liverpool fall under Class A Part 14 GPDO 2015 Permitted Development — no planning permission required. Exceptions: listed buildings, AONBs, ground-mount above 9m × 9m × 4m height. Liverpool City Council planning officers handle any consultation as part of the project.
Can we install solar on asbestos cement roofs near Liverpool?
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. The PV business case routinely pays for 60–100% of the re-roof over 25 years. We deliver this routinely across Merseyside / West Lancashire.
How long does a G99 grid connection take from Scottish Power Energy Networks?
Scottish Power Energy Networks typically quotes 65–90 working days for the technical study, with full connection timelines of 6–14 months on most rural feeders. We submit G99 immediately after structural survey. For export-constrained sites we design "no-export" systems sized for self-consumption that complete in 6–8 weeks.
