Solar Panels in Northampton: Costs, Yields and East Midlands Solar

Updated 2026-04-075 min read

Does solar work in Northampton?

Northampton sits in the East Midlands, which receives annual irradiance of around 950–1,050 kWh/m². Typical panel yield is approximately 850–950 kWh per kWp per year. A 4 kWp south-facing system in Northampton generates roughly 3,400–3,800 kWh per year — a meaningful offset against electricity bills.

The town's flat and gently rolling terrain means very few properties suffer from shading issues caused by hillside positioning. Much of Northampton's post-1970s housing stock — built during the town's expansion as a designated growth centre — has straightforward rooflines well suited to solar.

How much does solar cost in Northampton?

Installation costs in Northampton track the England average of around £1,591 per kWp. A typical 4 kWp system costs in the range of £5,500–£7,000. Northampton's growing installer market, supported by the town's logistics and commercial solar sector, keeps residential pricing competitive.

Your electricity network: NGED

Northampton is served by NGED — National Grid Electricity Distribution (nationalgrid.co.uk/electricity-distribution), which covers the Midlands and South West of England. NGED was formerly known as Western Power Distribution (WPD) — the name changed in 2023.

G98 Fit and Inform notifications (systems up to 3.68 kW per phase) and G99 pre-approvals (larger systems) are submitted to NGED by your installer. NGED has an online portal for G98 submissions that most installers use routinely.

Typical system for Northampton homes

Northampton's housing stock is unusually varied for a town of its size. The older shoe-industry terraces in the eastern and central parts of the town suit 3–4 kWp systems on south or west-facing rear slopes. Interwar semis in areas like Abington, Kingsthorpe, and Far Cotton suit 4–5 kWp.

The large post-1970s estates — Weston Favell, Duston, Upton, and the Grange Park area — were built as part of Northampton's planned expansion and often have generous plot sizes, simple roof geometry, and south-facing aspects. These estates frequently suit 5–6 kWp systems, and many already have newer roofing that works well with panel fixings.

New-build estates: check your roof orientation before buying

Northampton has seen significant new-build development in recent years. If you are purchasing a new property, ask the developer which direction the principal roof slope faces. Developers are not required to optimise for solar, and east-facing rear slopes are common on estates where plots are arranged along north-south roads.

Local grants and schemes

ECO4 — available to low-income and vulnerable households meeting eligibility criteria. Inner Northampton areas with higher deprivation ratings have stronger eligibility; use the national ECO4 checker at gov.uk or contact West Northamptonshire Council for referral routes.

Planning in Northampton

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

Northampton has several conservation areas, including parts of the historic town centre and the Abington Park area. If your property is in a conservation area or is listed, contact West Northamptonshire Council's planning department before proceeding.
