Do you need planning permission for solar panels in Bedfordshire? For most houses, no. Bedford Borough Council’s own summary says installations will generally not need planning permission, but may in some cases, such as conservation areas and listed buildings. This guide sets out what those cases are for the three councils it covers, Bedford Borough, Central Bedfordshire and Luton, using the national rule alongside each council’s own conservation-area and Article 4 lists. For what an installation itself involves, see our page on solar panels in Bedfordshire.
The short answer: permitted development, with exceptions
The rule is Schedule 2, Part 14, Class A of the Town and Country Planning (General Permitted Development) (England) Order 2015, as amended by S.I. 2026/896 and in force from 27 August 2026. Under Class A, solar equipment on a house is permitted development, which means no planning application, as long as it meets the conditions below. The Order is the same whether the house is in Kempston, Leighton Buzzard or Luton. What changes from street to street is the designations, and those are local.
Five things can change the picture: a conservation area, a flat roof on designated land, panels in the garden rather than on the roof, a listed building and an Article 4 direction. Only two of them can remove the right outright: a listed building, which sits outside Class A altogether, and an Article 4 direction that covers solar. The other three add a condition or a step. That is the precise version of Bedford Borough’s “may”: the answer turns on where your house is and what kind of roof it has.
The conditions for a pitched roof
Most households in all three council areas live in houses, which is where Class A applies. Adding the 2021 Census shares for detached, semi-detached and terraced homes gives 87.1% of households in Central Bedfordshire, 80.7% in Bedford Borough and 75.2% in Luton (our arithmetic on the ONS figures). For a roof-slope array on any of those houses, the Order sets four conditions. The panels must not protrude more than 0.2 m beyond the roof slope. They must not sit higher than the highest part of the roof, excluding chimneys. They must be sited to minimise the effect on the building’s appearance. And they must be removed when no longer needed.
The 0.2 m figure is a protrusion limit and nothing more. It says nothing about which way the slope faces or whether the panels can be seen from the road. Luton has the highest share of semi-detached homes of the three council areas, 40.3% of households on the 2021 Census, against 34.4% in Central Bedfordshire and 33.0% in Bedford Borough. Outside the exceptions below, a semi in Luton or Dunstable whose best slope faces the street is judged on the same four conditions as one whose best slope faces the garden. Wall-mounted equipment has its own figures: 0.2 m where the wall abuts a highway, 0.4 m otherwise.
Conservation areas in Bedford Borough, Central Bedfordshire and Luton
Bedford Borough Council lists 29 conservation areas, including Bedford itself, Kempston, Elstow, Biddenham, Harrold, Sharnbrook, Turvey, Stewartby, Great Barford and Cardington. It publishes appraisals and management plans for Bedford, Biddenham, Bletsoe, Elstow, Hinwick, Little Barford and Stewartby. Central Bedfordshire has around 60, among them Dunstable, Houghton Regis, Totternhoe, Leighton, Linslade, Biggleswade, Sandy, Potton, Ampthill, Woburn, Toddington and Shefford. Luton has five. Three are primarily commercial: the town centre, Plaiters’ Lea (The Hat District) and High Town Road. Two are primarily residential: Rothesay, designated in 2003, and Luton South, designated in 2010.
Living in one of them does not, on its own, stop you fitting roof-mounted solar. Under Class A as amended, the conservation-area exclusion applies only to equipment installed on a wall, balcony or roof enclosure which fronts a highway. Roof slopes are not restricted, and the clause draws no line between a slope that faces the street and one that faces the garden. So a house in the Elstow or Ampthill conservation area keeps its roof-slope rights on the ordinary conditions, front slope included, unless it is listed or an Article 4 direction says otherwise.
To find out whether your house is in one, Central Bedfordshire’s heritage pages include a map and a postcode search that shows whether a property is in a conservation area and whether there are listed properties nearby. Bedford Borough publishes a map for each of its 29 areas, and Luton’s conservation-area page names its five.
Flat roofs and panels in the garden
On a flat roof, the equipment must not sit more than 0.6 m above the highest part of the roof. On article 2(3) land, which under the Order includes conservation areas, National Landscapes, National Parks, the Broads and World Heritage Sites, a flat-roof array also needs an application to the council for a determination on whether prior approval of its appearance is required, made before work starts. So a flat-roofed extension on a house in the Kempston, Potton or Rothesay conservation area means an application to Bedford Borough, Central Bedfordshire or Luton respectively before the panels go on. It is a step, not a refusal. If you are unsure whether your home sits on article 2(3) land, the council’s planning team can confirm it for your address.
Stand-alone panels in the garden are not Class A at all; they fall under Class B. Under the 2026 Order, a prior-approval determination is needed first where any part of the array would sit in a conservation area and nearer to a highway that bounds the curtilage (the land that goes with the house) than the part of the house nearest that highway, or on article 2(3) land within 5 metres of the curtilage boundary. In Central Bedfordshire, where 29.3% of households live in detached houses, a long garden in a village conservation area such as Totternhoe or Woburn makes the position of the array what decides whether that step applies. Class B has further limits of its own, so read it in full against your plot before anyone measures up.
Listed buildings
Listed buildings are the clear exception. Class A does not permit solar on a house, or on a building within its curtilage, if the house is listed, so the permitted development route is closed. Separately, Historic England says consent is required for any type of PV installation on a listed building. In Central Bedfordshire, the council’s postcode search shows whether there are listed properties near your address; in Bedford Borough, start with the council’s Historic areas and buildings page; in Luton, ask the council’s planning team. If your house is listed, the conversation starts with the council, not with an installer.
Article 4 directions in the three council areas
An Article 4 direction lets a council remove permitted development rights in a defined area, and it is the one mechanism that can take roof-slope rights away street by street. Two readings matter. A direction that removes roof-alteration rights does not automatically remove the separate right to install solar, and a direction applies only to the land it names. Bedford Borough has two, Central Bedfordshire lists six and Luton’s cover change of use, a mast and parcels of land, so the detail differs by council.
Bedford Borough. One direction, in force since November 2020, covers changes of use to small houses in multiple occupation in the urban areas of Bedford and Kempston; it is about change of use, not roofs. The other was created in 1987 to protect parts of the Stewartby Conservation Area. We have not been able to confirm from the published copy whether the Stewartby direction touches solar, so if you live in the conservation area there, ask the council before work starts.
Central Bedfordshire. The council’s page lists six directions: the Wrest Park Estate at Silsoe, Fairfield parish, the Toddington Conservation Area, land at Lower Sundon, the Husborne Crawley Conservation Area, and land around the Sandhouse Public House at Heath and Reach. Two sit on conservation areas and cover householder works. In Toddington, permission is needed for householder extensions, front porches, outbuildings, hardstanding, fuel storage tanks, walls and fences, and dropped kerbs; Husborne Crawley’s direction covers the same list plus painting the exterior. The council’s published summary does not list solar equipment for either. Fairfield’s direction, in force from 5 January 2021, covers roof enlargements, additional storeys and porches, which shows why the detail matters: a direction about roof enlargements is not, on its face, a direction about solar. The summaries are not the full direction texts, so if you live in the Toddington or Husborne Crawley conservation areas or in Fairfield parish, check the direction itself with the council before work starts.
Luton. The current directions withdraw the right to change commercial premises to homes in the town centre (2023), Butterfield Green and Business Park (2022) and Capability Green (2022), and cover a telecommunications mast at Wolston Close (2002), enclosure and access on land at Hayling Drive and Wigmore Lane (1975), and enclosure on land at Hayhurst Road and Stanton Road (1960). None is described as covering householder solar.
Flats, and homes you rent
Everything above is the position for a house. Purpose-built flats are more common in Luton than in the other two council areas: the 2021 Census puts 20.5% of Luton households in purpose-built blocks of flats, against 14.2% in Bedford Borough and 10.2% in Central Bedfordshire. In a flat the roof is usually not yours to alter without the freeholder’s consent, and roof space rarely divides neatly between leaseholders, so the first question is consent and roof access rather than planning; the planning position for the building is one to confirm with the council. Luton also has the highest private-rented share of the three, 29.0% of households, and if you rent, the decision sits with your landlord.
Building regulations, MCS and UK Power Networks
Planning is one of three sets of paperwork. The second is the Building Regulations. Historic England notes that all PV installations must comply with Building Regulations Parts A (structure), B (fire safety) and P (electrical safety), with the council’s Building Control notified, whichever of Bedford Borough, Central Bedfordshire or Luton that is. We are a NAPIT member (73495); NAPIT is a government-approved scheme for registering electrical installers, and it covers the electrical work in every installation. We are also MCS-certified for solar PV and battery storage, with certification held via NAPIT, and HIES Consumer Code members (HCE/A/1392). Smart Export Guarantee payments need an MCS certificate (or an accredited equivalent), which arrives with the electrical certification after the installation is registered.
The third is the electricity network. Most of Bedfordshire is on UK Power Networks’ network: its history page says its Eastern predecessor managed the cables and lines in most of the county, and its area checker confirms a postcode. Under the Energy Networks Association’s G98 rule, a system up to 16 A per phase, 3.68 kW, is notified before commissioning or no later than 28 days after it. Anything larger needs a G99 application approved before the work starts, and a 4 kW inverter, at 17.39 A, is just over that line. UK Power Networks says it automatically approves an application where the installation’s maximum export, after any export limitation, is under 5 kW. The installer contacts UK Power Networks on your behalf. If no supply upgrade is needed there is nothing to pay UK Power Networks; if one is, it says the cost and timing vary from project to project.
Once planning is clear: the roof matters more than the town
PVGIS 5.3, the European Commission’s solar calculator, gives about 3,999 kWh a year from a 4 kWp array facing due south at 35° in Bedford. Across five towns, from Leighton Buzzard (about 3,948 kWh) to Biggleswade (about 4,007 kWh), the spread is about 59 kWh, smaller than the year-to-year variation at any one of them (our arithmetic on five PVGIS runs: PVGIS-SARAH3 2005–2023, 14% system losses, run 15 October 2026). East- and west-facing roofs make less, and shading changes the answer more than the town does. Our page on solar panel costs in Bedfordshire sets out how an installation is priced, and solar panel grants in Bedfordshire covers the income-linked schemes, which are a separate question from planning.

What to check before you ask for a quote
Check three things, in order. First, the designation: use Central Bedfordshire’s postcode search, Bedford Borough’s conservation-area maps or Luton’s list of five to see whether your house is in a conservation area, and ask the council if you are unsure whether it is listed or within the curtilage of a listed building. Second, the Article 4 position if you live in the Stewartby, Toddington or Husborne Crawley conservation areas or in Fairfield parish. Third, the roof: pitched, flat or garden, because each sits under a different rule above.
Then ask the installer to screen designations at the survey. We do: a listed building, a flat roof in a conservation area, a highway-facing wall or balcony, or a property in one of those Article 4 areas gets flagged before a quote is written, so the conversation with Bedford Borough, Central Bedfordshire or Luton happens first. We do not make planning or prior-approval applications on a customer’s behalf, and we would rather say so at the survey than leave you to find out later.
