The short answer
Manchester businesses can make commercial solar pay despite the northern latitude, because high daytime electricity use is what drives returns, not sunshine alone. The grid is run by Electricity North West. We match you with a vetted installer covering Greater Manchester for a free, no-obligation site survey.
Picking a commercial solar installer is the step where businesses most often get a poor deal — the Manchester market has plenty of firms, and quality varies. This page covers what is specific to going solar in Manchester; our guide to choosing an installer sets out the full vetting criteria, and our quote-comparison checklist shows what a good quote must contain.
Who runs the grid in Manchester?
Greater Manchester is served by Electricity North West. Your installer applies to them for the grid connection — a G99 application for exporting systems, typically 8–12 weeks. In parts of the conurbation the network is constrained, so checking connection headroom early is worth doing.

How much will a roof generate in Manchester?
The North West gets less sunshine than southern England, so generation per kWp runs a little below the UK average of around 950 kWh per kWp per year. It is still comfortably cash-positive for a business that uses most of its power during the day.
The number that matters most is how much you use during daylight: every unit you generate and use yourself displaces grid power at 25–30p. Our payback and ROI guide works through the returns, or get a figure for your own roof with the calculator below.
Are there solar grants for Manchester businesses?
Greater Manchester channelled UK Shared Prosperity Fund money into business energy support. UKSPF closed to new applications in March 2026; its successor, the Local Growth Fund, operates in the mayoral areas including Greater Manchester — so check the current rounds before relying on one.
On top of any local scheme, every UK business can use the £1m Annual Investment Allowance to deduct the cost from profits — worth roughly 25% of the project back at the 25% corporation tax rate. Our grants and tax relief guide has the national picture.
The Manchester installer market
Manchester's commercial solar field is a mix of regional specialists and nationals with a local presence. The choice is wide, which is exactly why independent vetting on certification, insurance and track record is worth the step before you commit.
Planning permission in Manchester
Permitted development covers most commercial rooftop solar in Manchester. Conservation areas and listed buildings — common in the city centre and inner suburbs — are the main exceptions where full planning permission may apply.
