Solar panel installation cost in Bolton & Wigan
Solar panels turn daylight into electricity you use in the house, and export what you do not use for a small payment. A typical Bolton or Wigan semi fits around eight panels. Price depends mostly on how many panels the roof takes and how hard the roof is to reach.

Supply and fit, at the current 0% VAT rate. MyJobQuote’s August 2026 UK average is £7,250, and labour alone is about £2,000 to £2,500 of a 4kW system. Its figures are UK-wide; it does not publish North West prices.
Usually included
- Panels, roof mounting kit and an inverter
- Cabling to the consumer unit and a generation meter
- Testing, commissioning and an MCS certificate
- Notifying the network operator, Electricity North West in Bolton and Wigan
Often extra
- A battery, if you want to store daytime power for the evening
- Scaffolding, on some quotes
- A consumer unit upgrade if the board cannot take a new circuit
- Bird proofing under the panels (£100 to £300 on MyJobQuote’s figures)
- A replacement inverter, typically needed after 10 to 15 years (£800 to £1,500)
What changes the price
- Roof size and direction
- A large south, east or west facing roof takes more panels. Shading from chimneys, trees or neighbouring houses cuts output.
- Access
- Three-storey terraces, steep roofs and conservatories under the roof need more scaffolding.
- The consumer unit
- An old fuse box usually has to be replaced before solar can be connected.
- Panels and inverter brand
- Premium high-efficiency panels cost more per panel but can fit more power on a small roof.
How long it takes
Usually 1 to 2 days on site, after a survey. Scaffolding often goes up a day or two before and comes down after.
Rules and certificates
Use an MCS-certified installer: MCS certification is what most electricity suppliers ask for before they pay you for exported power. Installing solar on a house in England is usually permitted development, so no planning application is needed, provided the panels on a pitched roof stick out no more than 200mm and do not go above the ridge. Listed buildings, and roofs facing the road in a conservation area, are exceptions, so check with Bolton or Wigan Council if either applies. The installer notifies Electricity North West: most home systems are connected first and notified afterwards, while bigger systems need approval before they are fitted. Installing solar panels in a home is zero-rated for VAT until 31 March 2027, after which GOV.UK says the rate goes back to 5%.
For grants, export payments and how solar, batteries and EV chargers fit together, see the solar and renewables guide.
Questions people ask
Are solar panels worth it in Bolton and Wigan?
For many homes, yes, but the North West gets less sun than the south of England, so expect your output towards the lower end of UK estimates. MyJobQuote’s UK figures are £400 to £800 a year off bills, plus £50 to £150 a year in export payments, and a break-even of about 8 to 12 years. You save most if you use the power during the day, or store it in a battery.
Do solar panels work when it is cloudy?
Yes, but they make much less. Output depends on daylight, not heat, so a bright cold day is good for solar and a dull winter day is poor.
Will I be paid for the electricity I export?
Through the Smart Export Guarantee, some electricity suppliers must offer to pay you for power you send to the grid. Rates vary a lot between suppliers and tariffs, so shop around. You usually need a smart meter and an MCS certificate, and you do not have to use the same supplier for export as for your normal electricity.
Can I get free solar panels?
Possibly, through the Warm Homes: Local Grant, which councils in England deliver. It covers privately owned or privately rented homes with an EPC rating of D to G and, usually, a household income of £36,000 or less. Apply on GOV.UK and your council will contact you about a survey.
Do I need planning permission?
Usually not on a house. The main exceptions are listed buildings and conservation areas, where panels cannot go on a roof slope facing the road. Flats and leasehold homes may need the freeholder’s permission.
Should I get a battery too?
A battery stores the power you make during the day so you can use it in the evening, when most homes use the most. It adds roughly £4,500 to £6,500 if fitted at the same time, and is cheaper to add then than later. See our battery storage guide.
