Solar Panels Lincolnshire: Grants, Yield and Local Rules

A south-facing roof in Lincoln generates about 1,017 kWh per kWp a year on the EU's PVGIS model, which is more than Nottingham, Leicester, Birmingham, Sheffield or Leeds, and every unit you use saves 25.36p at the East Midlands price cap rate. A typical 4.5kWp system would make about 4,576 kWh a year.

How much electricity solar panels make in Lincolnshire

A south-facing 1kWp system at 35 degrees in Lincoln generates about 1,017 kWh a year, according to the EU's PVGIS model. That ranks 17 of the 31 areas we cover, which run from 850 kWh in Glasgow to 1,177 kWh in Sussex. East and west roofs still work, at roughly a fifth less.

Roof direction (35° pitch)	Per kWp a year	June	December
South-facing	1,017 kWh	119 kWh	35 kWh
East-facing	806 kWh	113 kWh	13 kWh
West-facing	778 kWh	111 kWh	14 kWh

PVGIS is a modelled figure for an unshaded roof with 14% system losses, and it runs higher than the MCS method installers must use for your written estimate, which gives roughly 800 to 950 kWh per kWp for a well-oriented UK roof. Use PVGIS to compare places and the installer's MCS estimate to plan your budget. Our guides to which direction panels should face and how much electricity solar panels produce go further.

What that electricity is worth in Lincolnshire

Every unit you use yourself saves 25.36p, the Ofgem price cap rate for direct debit customers in the East Midlands region from 1 October to 31 December 2026. The Great Britain average is 26.32p. Every unit you export earns whatever your Smart Export Guarantee tariff pays, which the Energy Saving Trust puts at around 12p typically.

Take the Energy Saving Trust's typical 4.5kWp home system. On the PVGIS figure for Lincolnshire it would generate about 4,576 kWh a year. If you used all of it, that would be worth about £1,160. If you exported all of it, about £549. Real homes sit between the two, and a battery or daytime use pushes you towards the higher figure. The Energy Saving Trust prices that typical system at around £7,600. See our solar panel cost guide and current export rates.

The Lincolnshire countryside has more than twice the solar of its city

Five of Lincolnshire's seven districts sit in the top 50 of the UK's 361 local authorities for solar installations per 1,000 households, while the City of Lincoln is 256th. On our count from the government's local authority table, at the end of 2025 Boston ran at about 127 installations per 1,000 households, South Holland about 125, East Lindsey about 124, North Kesteven about 122 and West Lindsey about 121. South Kesteven, which takes in Grantham and Stamford, was about 92. Lincoln itself had 2,122 installations across 42,500 households, about 50 per 1,000, which is below the UK average of 68.6. North Lincolnshire runs at about 115 per 1,000, and North East Lincolnshire, covering Grimsby and Cleethorpes, at about 55.

Across the seven districts that is 36,068 installations at the end of 2025, up from 29,957 a year earlier, a rise of 20.4% against 16% across the UK. The East Midlands was also the fastest growing of the five English regions the government named as the UK's biggest for solar deployment, at 17% in the year to July 2026, ahead of the North West on 16%, the East of England on 15%, the South East on 14% and the South West on 13%. Two cautions on the district numbers. The government warns that its 2025 figures were produced before the latest postcode lookup, so a large number of installations are still unassigned and the counts will be revised upward. And Lincolnshire's megawatts are not mostly roofs: East Lindsey's 8,026 installations carry 177.85 MW, an average of about 22 kW each, which is field scale, while Lincoln's 2,122 carry 9.98 MW, an average of about 4.7 kW, which is a house. Both averages are our own division of the government's capacity and installation tables, so the per-household rate is the number that tells you about roofs.

The housing explains most of the gap. Census 2021 found 45.1% of the 333,550 households in the Lincolnshire County Council area in a detached home, against 22.9% across England, with 29.8% semi-detached, 15.2% terraced and only 6.6% in purpose-built flats. That is roughly double the national detached share, and a detached house is the easy case for solar: one owner, no freeholder to ask, and usually a whole unshaded roof plane to work with. Lincoln is the other shape entirely, with 19.9% of its 42,509 households detached, 29.6% terraced and 16.0% in purpose-built flats. If you are in a flat, our guide to solar panels for flats covers the lease and freeholder questions first.

Lincolnshire has the cheapest electricity in Great Britain, and that cuts both ways

At 25.36p per unit, the East Midlands has the lowest electricity unit rate of the 14 price cap regions in Great Britain, against a Great Britain average of 26.32p and 27.86p in Merseyside and Northern Wales. That is good news every month and awkward news for a solar payback sum, because what solar saves you is the cost of the units you no longer buy. The same roof pays back more slowly in Lincoln than it would in Liverpool. It does not change the engineering, only the arithmetic, and the gap is about two and a half pence a unit.

What follows from that is that self-use matters more here than in an expensive region, because the gap between using a unit and exporting it is narrower. A Smart Export Guarantee tariff at around 12p is roughly half the 25.36p you save by using a unit yourself, so moving your washing, hot water and car charging into daylight does more work in Lincolnshire than a bigger array would. Our guides to solar battery storage and how many panels you need cover the sizing question, and current export rates lists what suppliers are paying.

One group of Lincolnshire homes sits outside that arithmetic altogether. At Census 2021, 39,818 households in the county, 11.9%, heated with oil only, against 3.2% across England, and only 65.7% used mains gas only against 74.0% nationally. A further 7.1% were on electricity only and 1.0% had no central heating at all. Lincoln is almost entirely on the mains, at 80.7% gas only and 55 households on oil. If you are one of the oil-heated homes, solar on its own still only cuts the electricity bill, and the combination worth modelling is solar with a battery and then electric heating or a heat pump, so that the generation you cannot use in the afternoon is not simply exported cheaply. Our heat pump cost guide covers the Boiler Upgrade Scheme, which pays a higher rate for homes off the gas grid.

Grants in Lincolnshire: the same scheme, two different answers

Whether the Warm Homes: Local Grant pays for solar panels in Lincolnshire depends on which half of the county you live in, and right now it is closed or waiting-listed in all of it. The four central districts run the scheme through West Lindsey District Council, acting for West Lindsey, City of Lincoln, North Kesteven and South Kesteven. South Kesteven's own page says the funding covers a wide range of retrofit measures including roof and wall insulation, solar PV and other low carbon heating solutions. West Lindsey, which runs it for all four, says it is not currently taking new applications because of unprecedented demand. In the south and east, East Lindsey District Council runs it for East Lindsey, Boston Borough and South Holland, and those three describe the same national grant as insulation and efficient heating and never mention solar at all. East Lindsey is operating a waiting list, the GOV.UK application route is paused, the programme runs until March 2028 and the councils warn they cannot guarantee processing an application before it ends. In North East Lincolnshire the scheme is on hold and every enquiry goes on a waiting list.

The eligibility rules are the same wherever you are: a privately owned or privately rented home with an EPC of D, E, F or G, and a gross household income usually of 36,000 pounds a year or less, with priority where savings do not exceed 16,000 pounds. Certain postcodes and certain benefits can qualify a higher income. There is also an ECO4 route. West Lindsey, acting for the central and southern councils under their published statement of intent, lists solar and renewable energy technologies among ECO4 measures and will assess you on a gross household income under 31,000 pounds, on two deprivation or Council Tax rebate proxies, or on an NHS referral, but the council states that ECO4 funding is limited and close to being fully allocated. The council only assesses eligibility; it does not fund or install anything. Our guide to solar panel grants in the UK covers what exists nationally, and there is no universal solar grant to fall back on.

One administrative point is worth knowing before you ring anyone. On 29 October 2026 the government withdrew its July decision on reorganising Lincolnshire, North Lincolnshire and North East Lincolnshire, so the planned unitary councils are not confirmed, every submitted option is back under consideration with an outcome promised by early 2027, new councils are now due for 2029 with shadow elections in May 2028, and the May 2027 local elections run on existing boundaries. Until then your existing district or borough council still handles both planning and grants. The councils' own reorganisation hub still shows an April 2028 vesting day, which is out of date.

Planning: Stamford's Article 4 is the one that catches people

In Stamford you need planning permission for solar panels on any elevation that faces onto and is visible from a highway, footpath or open space, even on an ordinary unlisted house. South Kesteven District Council has had an Article 4 Direction in force since 1 December 2018 covering unlisted residential and commercial buildings across the whole Stamford Conservation Area, and for unlisted houses and commercial properties it removes the permitted development right to install, alter or replace solar panels and other solar thermal equipment where the work would face onto and be visible from a highway, footpath or open space. A rear slope nobody can see from the street is not caught. That is stricter than the standard England rule, which in a conservation area only excludes panels on a wall fronting a highway: in Stamford the roof slope counts too, and footpaths and open spaces count as well as roads. Stamford was the first urban conservation area designated anywhere in England, in 1967, and South Kesteven now lists 48 conservation areas in total with around 2,150 listed buildings, roughly 600 of them in Stamford alone, plus 120 Grade I buildings. Listed building consent is needed for changes that alter a building's special character, and the council warns that doing the work without it is a criminal offence carrying a maximum 20,000 pound fine or six months in prison. North Kesteven, around Sleaford, has 36 conservation areas and three Article 4 directions, at Leasingham, Wilsford and Heckington.

Everywhere else in Lincolnshire the England rules apply, and on a house roof-mounted solar is usually permitted development. The designation that changes them is the Lincolnshire Wolds National Landscape, still legally an Area of Outstanding Natural Beauty, which has covered 558 square kilometres between Lincoln and the coast since 1973 and spans the areas of four authorities named in its management plan: Lincolnshire County Council, East Lindsey, West Lindsey and North East Lincolnshire. Your application itself goes to the district or unitary council, not the county. Both the Wolds and every conservation area in the county count as article 2(3) land under Schedule 1 of the permitted development order, and on article 2(3) land three things change. Panels on a flat roof mean applying to the council first for a determination of whether prior approval is needed. A stand-alone ground array within 5 metres of your boundary needs the same determination. And in a conservation area panels cannot go on a wall, balcony or roof enclosure that fronts a highway, which is about the elevation facing the road rather than the roof slope behind it. Panels on a listed building are outside permitted development altogether. See our guides to permitted development, conservation areas and listed buildings.

Lincolnshire has two network operators, not one

Most of Lincolnshire is National Grid Electricity Distribution's East Midlands licence area, but the north of the county is Northern Powergrid, and the boundary follows the electricity licence areas rather than the council boundary. The East Midlands area covers about 16,000 square kilometres and 2.7 million customers, runs from Coventry and Uttoxeter in the west to the Wash on the east coast, and National Grid describes its geography as ranging from low-lying farmland in Lincolnshire to the Peak District in Derbyshire. Three of its fourteen grid supply points carry Lincolnshire's 33 kV networks: Bicker Fen covers the Grantham, Sleaford and Skegness areas, Walpole covers Boston, Spalding, South Holland, Bourne and Stamford, and West Burton covers Lincoln. Northern Powergrid says it covers the North East, Yorkshire and northern Lincolnshire, so Scunthorpe and Grimsby deal with a different company from Lincoln or Boston. When we put five Lincolnshire postcodes through the Energy Networks Association's operator lookup on 2 November 2026, Lincoln, Boston, Grantham, Spalding and Skegness all came back as National Grid, while a Gainsborough postcode inside the Lincolnshire County Council area came back as Northern Powergrid. The Energy Networks Association says its lookup should not be relied on for commercial decisions, so treat it as a first check and have your installer confirm which network you are on before they fill anything in.

In the National Grid area nobody has to approve a normal domestic solar job first. An installation under 16 A per phase using type-tested equipment follows the G98 fit-and-notify route, and the notification has to reach National Grid within 28 days of commissioning. Above 16 A per phase, which National Grid states as 3.68 kW, it becomes a G99 application made before the work instead, and that is the line most single-phase homes cross as soon as a battery or a larger inverter is added. There is a middle path: National Grid runs a G99 fast track for single-phase homes with G98-compliant solar up to 16 A and G98-compliant storage up to 16 A, provided a G100-compliant export limitation scheme holds total export to 16 A per phase or less. Ask your installer for the notification acknowledgement, because it is the proof your system is registered and your Smart Export Guarantee supplier will want it alongside the MCS certificate. Our G98 and G99 guide goes through the forms.

Worth knowing if an installer starts talking about export limits: National Grid's own network development report counts 204 constraints across the East Midlands, and about 30 of them sit in the six 33 kV areas covering Lincolnshire: six at Lincoln, six at Skegness, five at Boston, five across Grantham and Sleaford, four at Spalding and South Holland and four at Bourne and Stamford. The same report says over 900 generation and storage projects totalling 15.3 GW hold accepted connection offers that could connect to the East Midlands network in future. None of that stops a house connecting, but it is why an export limitation scheme comes up more often here than the headline G98 rule suggests.

Solar panels in Lincolnshire: frequently asked questions

Are solar panels worth it in Lincolnshire?

For most Lincolnshire houses, yes, and the roofs are unusually suitable: 45.1% of the county's households are detached, against 22.9% across England. A south-facing roof in Lincoln generates about 1,017 kWh per kWp a year on the PVGIS model, a typical 4.5kWp system would make about 4,576 kWh, and every unit you use saves 25.36p at the East Midlands price cap rate for October to December 2026. That rate is the cheapest of the 14 price cap regions in Great Britain, so the payback is slower here than in a dearer region and using your own generation matters more than adding panels.

Which part of Lincolnshire has the most solar panels?

Boston. It had 3,745 installations across 29,400 households at the end of 2025, about 127 per 1,000 on our count from the government's local authority data, which is 27th among the UK's 361 local authorities. South Holland, East Lindsey, North Kesteven and West Lindsey all sit between about 121 and 125 per 1,000. The City of Lincoln is the outlier at about 50 per 1,000, which is 256th and below the UK average of 68.6.

Can I get a grant for solar panels in Lincolnshire?

Not at the moment. The Warm Homes: Local Grant is closed to new applicants across West Lindsey, City of Lincoln, North Kesteven and South Kesteven, and East Lindsey is running a waiting list for East Lindsey, Boston and South Holland, as is North East Lincolnshire. The central districts do list solar PV as a funded measure; the three southern ones describe the same grant as insulation and heating only. West Lindsey also assesses households for ECO4, which can include solar, but says that funding is limited and close to being fully allocated.

Do I need planning permission for solar panels in Lincolnshire?

Usually not on a house, with one clear exception: Stamford. South Kesteven's Article 4 Direction, in force since 1 December 2018, removes the permitted development right for solar across the whole Stamford Conservation Area, including unlisted houses, wherever the work would face onto and be visible from a highway, footpath or open space, so a street-facing roof slope needs a planning application while a hidden rear slope does not. Inside the Lincolnshire Wolds National Landscape and in any conservation area, a flat-roof array or a ground array within 5 metres of the boundary needs a prior approval determination, and panels cannot go on a wall or balcony fronting a highway. Listed buildings need listed building consent.

Who is the network operator for solar in Lincolnshire?

For most of the county, National Grid Electricity Distribution in its East Midlands licence area. Northern Powergrid covers northern Lincolnshire, including Scunthorpe and Grimsby, and when we checked the Energy Networks Association lookup on 2 November 2026 a Gainsborough postcode inside the county council area also came back as Northern Powergrid, so check your own postcode. In the National Grid area your installer notifies rather than applies if the system is under 16 A per phase, within 28 days of commissioning; above 16 A, which National Grid states as 3.68 kW, it becomes a G99 application made beforehand.
