Solar panel installer Wigan: how to choose one and check the quote
Whether you live in a Hindley semi, a Pemberton terrace or a detached house out towards Standish, the hard part of going solar is picking the firm. This guide sets out the checks worth making on any installer, then lets you test a quote against published prices and the output your roof should give.

Check a solar quote against the figures
Type in what the quote says. Nothing you enter leaves this page.
The price figures are means of MCS-certified installs across the North West in 2025/26, not a quote for your house: scaffolding, roof access, panel choice and shading all move a real price. A battery in the price is taken out at the DESNZ median per kWh for its size band (our arithmetic). Use a gap as a question to ask, not as proof of a bad quote.
Five checks to make on any solar installer
We do not install anything, take bookings or recommend a firm. What we can do is set out the checks that the bodies running the schemes themselves ask you to make, and say where to make each one. None of them takes more than a few minutes, and an installer worth hiring will expect you to ask.
How to make each check, step by step · What a quote should include
What a fair price looks like in the North West
The government publishes what households paid for MCS-certified solar each year. Its 2025/26 figures cover 22,981 MCS-certified installations in the North West: systems of up to 4 kW came to a mean of £2,021 per kW, and systems of 4 to 10 kW to £1,768 per kW (DESNZ). Larger systems cost less per kW because the fixed costs, scaffolding and the inverter among them, are spread further.
The North West sits at the upper end of the regions for small systems. That makes the regional figure a fair yardstick for a Wigan quote, and a reason not to compare it with a national headline price. Divide any quote by its size in kW and see where it lands; the checker above does that for you, and takes out a battery if the price includes one.
Installed solar panels are zero-rated for VAT until 31 March 2027; from 1 April 2027 the rate becomes 5% (HMRC), roughly £50 more for each £1,000 of work, by our arithmetic. A quote should show the VAT line clearly either way.
| Size | Mean per kW | About | kWh a year |
|---|---|---|---|
| 3 kW | £2,021 | £6,050 | 2,781 |
| 5 kW | £1,768 | £8,850 | 4,635 |
What a roof in the borough should make
PVGIS, the European Commission's solar model, gives a south-facing roof at 35° about 927 kWh a year for each kW of panels in central Wigan, and 929 at the best angle of about 40° (PVGIS 5.3). East and west roofs come out almost level here, at 737 and 743, so a semi whose back faces either way is still a fair prospect.
Across the twelve places we ran, from Orrell in the west to Leigh in the east, a south roof ranges only from 911 kWh per kW at Atherton to 936 at Orrell. Where you live in the borough matters far less than which way your roof faces and what shades it. That narrow spread is useful when checking a quote: if an installer's yearly figure is well above PVGIS for your direction, ask how they reached it.
A borough of semis and terraces
At the 2021 Census, 45.6% of Wigan households lived in a semi-detached house, well above England's 31.5%, and 26.1% in a terrace (ONS). The semi is at its most common in Winstanley, where it houses 60.6% of households, and in Golborne and Lowton West (55.6%). Terraces cluster in Wigan West (42.7%), Leigh West and Atherleigh.
A semi usually has a front and a back slope with a hipped or gabled end, which gives an installer two faces to choose between and room for a typical system. A terrace often has less usable roof once chimneys and rear extensions are taken out. Either way, a good quote names the slope, shows the panel layout on a drawing and gives the output for that slope, not the best one on the street.
Of the 154,590 properties on the borough's council tax list, 19.1% were built before 1919 and 15.6% from 2000 onwards (VOA 2026). 53.6% of Wigan homes with an EPC reach band C or above, close to England's 53.3%; for homes built before 1930 the share is 26.9% (ONS).
Help with the cost, and who it is for
In England there is no grant for solar panels for households that can pay for them; the government's Warm Homes Plan points those households to loans instead (Warm Homes Plan). A seller who says otherwise at your door is a reason to close it.
For lower-income households, the Greater Manchester Combined Authority runs the Warm Homes: Local Grant "GM Wide Scheme", and it lists solar PV and battery storage among its measures. Owner-occupied homes at EPC D to G can qualify, as can privately rented homes at D or E. The household also needs one route in: a postcode in the most deprived income deciles, a means-tested benefit, two of the listed proxies, or a combined income below £36,000. GMCA's page lists up to £30,000 for an owner-occupier, and measures follow a retrofit assessment (GMCA); national guidance has since raised the caps to £16,600 per part (DESNZ). GMCA's page does not list the boroughs one by one, so ask its Retrofit Team whether your Wigan address is covered.
Anyone with panels can be paid for spare electricity: larger suppliers must offer an export rate above zero, each setting its own terms (Ofgem). An export tariff needs an MCS certificate, one more reason to check the installer. All the help with the cost
Planning and the 23 conservation areas
Roof panels on a house in England are normally permitted development, within limits rewritten from 27 August 2026 (SI 2026/896). Wigan Council lists 23 conservation areas, from Haigh Village and Standish to Bridgewater Canal (Leigh) and Wigan Pier (Wigan Council). In those areas roof panels inside the limits stay permitted, but panels on a wall or balcony facing a road need permission and a flat-roof scheme needs the council's prior approval.
Historic England counts 353 listed entries in the borough (Historic England); any work on a listed building needs listed building consent. An installer should tell you which of these applies before quoting, and say who will make any application. The planning rules in full
The local network
Wigan's electricity network is run by Electricity North West. For a system with inverters up to 16 amps per phase (3.68 kW on a single-phase supply), the installer commissions it and then notifies the network; anything larger, or solar plus a battery over that limit, needs an application before it is connected (Electricity North West).
A quote should say which route applies and that the installer handles the paperwork. How the connection works
When the seller comes to you
Wigan Council's Trading Standards team asks residents to report unwanted callers and gives advice on dealing with them; it also runs Neighbourhood Champions to help protect streets from doorstep crime (Wigan Council). The same page links a list of traders it describes as reliable and reputable, the Good Trader Scheme.
Pressure is the signal to watch for: a price that is only good today, a grant that needs signing for now, a survey that turns into a contract. Most contracts made at your home or online can be cancelled within 14 days (Consumer Contracts Regulations 2013), and RECC reminds buyers that the right depends on how and where the contract was made (RECC).
A busy market, so check before you choose
Solar is well established in the borough. Government figures count 6,529 solar PV installations of every size in Wigan at the end of 2025, up from 3,701 ten years earlier and 5,837 a year before (DESNZ). More firms chasing that work means more choice, and more reason to compare quotes like for like.
Once the panels are up, the paperwork matters as much as the panels: the MCS certificate, the electrical certificates, the network notification and the warranties. MCS says that from May 2026 its Customer Insights team may contact customers to verify their certificate and check that the installation was delivered to their satisfaction (MCS). If something does go wrong, RECC members give access to Green Homes Dispute Resolution at no cost to you (RECC).
- Search each firm on the MCS register and its consumer code.
- Get three written quotes for the same roof and the same size.
- Put each through the quote checker: price per kW and promised output.
- Ask who notifies Electricity North West, and when.
- Sign nothing on the doorstep; take the 14 days if you need them.
Five questions Wigan readers ask first
How do I find a good solar panel installer in Wigan?
Start with the MCS installer search rather than an advert, then check the firm belongs to a consumer code such as RECC or HIES. Get at least three quotes, as MCS suggests, and compare each one on price per kW and on the yearly output it promises against the PVGIS figure for your roof.
What should a solar installation cost in Wigan?
DESNZ figures for 2025/26 put the North West mean at £2,021 per kW for systems up to 4 kW and £1,768 per kW for 4 to 10 kW. A quote well above that is not automatically wrong, but it is worth asking what the extra pays for.
Is a solar installer who knocks on my door legitimate?
Some may be, but a sale made on the doorstep under time pressure is the classic warning sign. Wigan Council asks residents to report unwanted callers to its Trading Standards team. Most contracts made at your home can be cancelled within 14 days.
Do I need planning permission for solar panels in Wigan?
Usually not for panels on a house roof within the national limits. The borough has 23 conservation areas, where panels on a wall or balcony facing a road need permission, and listed buildings always need consent. Ask Wigan Council's planning team if in doubt.
Is there help with the cost of solar in Wigan?
For households that qualify, GMCA's Warm Homes: Local Grant lists solar PV and battery storage, for homes at EPC D to G and households with a qualifying postcode, a means-tested benefit or income under £36,000. Households that can pay get no solar grant, but installed solar carries 0% VAT until 31 March 2027.
