10 verified firms for Milton Keynes, with output and savings worked out for MK’s own sunshine and electricity prices.

Solar in Milton Keynes by the numbers
These numbers are calculated for Milton Keynes, not taken from a UK average. A 4kW system on a south-facing, 35° roof here is estimated to produce 3,942 kWh a year, peaking at 479 kWh in Jul and falling to 136 kWh in December.
- 3,942 kWh / yearEstimated output of a 4kW roof system in Milton Keynes
- 25.36p per kWhPrice-cap unit rate for the East Midlands region, Oct–Dec 2026 (GB average 26.32p)
- £400–£600 off your billIf you use 40–60% of what the panels make at home
- + £205–£305 export incomeThe rest sold at 13p/kWh on an open Smart Export Guarantee tariff
That adds up to about £705–£805 a year, recovering a typical £6,490 install in 8.1–9.2 years. MK is one of the sunnier places we cover outside East Anglia and the Thames estuary, but its East Midlands unit price is the lowest in Great Britain this quarter, so the value comes mainly from using solar power at home.

Frequently Asked Questions
Do Milton Keynes’ Article 4 directions affect solar panels?
In a few places. Most of the city’s Article 4 directions deal with HMOs or office conversions, but two matter for homeowners. In Wolverton, every house needs permission for changes to its front elevation, or side elevation on a corner plot. In Olney, extensions, alterations and exterior painting are controlled. Neither direction names solar panels, but a front-facing roof array in either area is worth raising with the council first. There are also 19 site-specific directions in villages such as Lavendon, Sherington, Castlethorpe and Bow Brickhill.
How much will panels produce in Milton Keynes?
About 3,942 kWh a year from a 4kW south-facing roof, according to PVGIS. That’s about 3.5% more than Leicester and 4% more than Derby, simply because MK is further south. July is the best month at around 479 kWh, and December the weakest at about 136 kWh.
What will a 4kW system save a Milton Keynes household?
Because MK is on the East Midlands price cap, 25.36p a unit this quarter and the lowest in Britain, each unit of solar you use at home is worth nearly double what you’d earn exporting it at 13p. Put in pounds, a 4kW roof brings in about £705 a year when 40% of its output is used in the house, climbing towards £805 when 60% is. Timers on appliances do more for an MK household than hunting for a higher export tariff.
What is MK Community Energy, and can it help me?
Milton Keynes Community Energy is a not-for-profit community benefit society set up in 2015 and backed by the city council’s Green Business Fund. It pays for, installs, owns and maintains solar panels on the roofs of local businesses, charities, schools, faith groups and sports clubs, which pay nothing upfront and, on MKCE’s figures, save over 25% on their energy bills on average. It has generated more than 3 million kWh and saved over 975 tonnes of CO2, with sites including Stony Stratford Town Council and Library. It doesn’t do private homes, but it reinvests surpluses into the Home Energy MK advice service.
Is the Warm Homes grant open in Milton Keynes yet?
Not yet. Milton Keynes City Council’s Warm Homes: Local Grant page says the scheme is “coming soon” and that formal applications have not opened. You can register interest now through the Warmer Homes eligibility checker, and Home Energy MK can advise on other routes such as ECO4, which runs until the end of 2026.
Do Milton Keynes’ newer homes suit solar?
Mostly, yes. Much of the city was built from the 1970s onwards, so roofs tend to be sound, uniform and free of the chimneys and dormers that shade older terraces. Low-pitched or flat roofs on some estates need tilted mounting frames, which add a little to the cost. Estate layouts also mean many homes have a clear south, east or west roof slope facing the garden rather than the street.
Final Thoughts
Milton Keynes is in a good position compared with some of its neighbours — several of its best-reviewed installers are based right in the city, from Bletchley to Newport Pagnell to Crownhill, with a couple of well-documented firms just over the border if you want to widen the search.
Get a handful of quotes from the list above, confirm accreditation directly for the firms where a review score wasn’t published, and let your roof start paying you back.
