Solar Panels in Wigan: Costs, Yields and Greater Manchester Solar

Updated 2026-04-075 min read

Does solar work in Wigan?

Wigan sits on the edge of Greater Manchester, receiving annual irradiance of around 900–950 kWh/m². Typical panel yield is approximately 800–860 kWh per kWp per year. A 4 kWp south-facing system in Wigan generates roughly 3,200–3,440 kWh per year — a meaningful contribution to household electricity needs.

Wigan's relatively flat landscape, particularly towards the town centre and surrounding areas like Leigh and Atherton, means most properties have clear sky access without significant shading. The borough's affordable housing stock makes the investment-to-savings ratio attractive for owner-occupiers.

How much does solar cost in Wigan?

Installation costs in Wigan broadly track the England average of around £1,591 per kWp. A typical 4 kWp system costs in the range of £5,500–£7,000. The wider Greater Manchester installer market means Wigan homeowners generally have good access to competitive pricing.

Your electricity network: ENW

Wigan is served by ENW — Electricity North West (enwl.co.uk), which covers the north-west of England including Greater Manchester, Lancashire, Cumbria, and Cheshire.

G98 Fit and Inform notifications (systems up to 3.68 kW per phase) and G99 pre-approvals (larger systems) are submitted to ENW by your installer.

Typical system for Wigan homes

Wigan's housing stock is heavily weighted toward Victorian and Edwardian terraces in the town centre and inner areas, with interwar council semis across much of the wider borough. Terraced properties typically suit 3–4 kWp systems on south or west-facing rear slopes.

Outer areas including Standish, Shevington, and Aspull have more modern and larger detached properties with south-facing aspects, where 5–6 kWp systems are a natural fit. Leigh and Golborne to the east of the borough also have a good mix of semis and bungalows suited to 4–5 kWp.

Terraced rooftops: use a compass or sun app before quoting

Many Wigan terraces were built on streets running east-west, giving rear roof slopes a south-facing aspect — ideal for solar. Before requesting quotes, confirm your rear slope's orientation using a compass or a free sun-position app. South and south-west are both excellent; north-facing rear slopes are not suitable for solar.

Local grants and schemes

ECO4 — available to low-income and vulnerable households. Inner Wigan and Leigh have significant areas of deprivation with above-average ECO4 eligibility. Contact Wigan Council's housing team or use the national ECO4 checker at gov.uk.
Warm Homes Local Grant — for properties with poor EPC ratings and lower household incomes.
Greater Manchester Combined Authority — the GMCA runs regional energy efficiency initiatives; check for current solar-specific programmes.
0% VAT on solar — UK-wide until March 2027.

Planning in Wigan

Standard GB permitted development rules apply across most of the Wigan borough. Solar panels can be installed without planning permission on most homes, subject to the 200 mm maximum projection above the roof plane.

Wigan has conservation areas in the historic town centre and some surrounding villages. If your property is within a conservation area or is listed, contact Wigan Council's planning department before proceeding.
