Maidstone Solar panels
Solar panels in Maidstone
An unshaded, south-facing 4 kWp array in Maidstone is modelled at 4,227 kWh a year, and on most of the town's houses, from Allington semis to Fant terraces, panels go up as permitted development within the size limits. The checks gather in and around the centre: six conservation areas, around 99 listed entries inside the Town Centre one alone, and High Street ward's blocks of flats, where the freeholder may have a say. We install as an MCS-certified firm from Keston, 21.8 miles away in a straight line, with the UK Power Networks G98 or G99 step included.

4,227 kWh a year at the Maidstone town point
For an unshaded 4 kWp array facing due south at 35°, the EU Joint Research Centre’s PVGIS model gives 4,227 kWh a year at the Maidstone town point, roughly 1,057 kWh for each kWp. Of the 13 towns on our list, only Tonbridge models higher, by 18 kWh; Croydon, the lowest, sits 123 kWh below.
DESNZ counted 5,715 solar PV sites in Maidstone Borough at the end of 2025, up 75% from 3,266 in 2020. That is about eight for every 100 households, more than in any other council area our towns fall in, though the count includes villages, businesses and ground-mounted sites. Their 36.8 MW generated 33,515 MWh in 2025, about 910 kWh per kW, short of the 1,057 modelled above: the borough total takes in every array whatever its direction or shading, and panels fitted during 2025 were not generating for the whole year.
Allington semis, Fant terraces, High Street flats
Census 2021 counted 39,772 households in the 11 wards of Maidstone’s built-up area, leaving out Bearsted, Boxley, Loose and the rural wards. 58.8% own their home and 2.0% are in shared ownership, against 67.4% owning across the borough. The rest rent, 21.2% privately and 17.9% from a social landlord, so roughly two households in five need the owner’s consent before panels go on.
The 11 wards sit far apart. In Allington, 86.6% of households own their home and 58.2% live in a semi-detached house. In Fant, the terrace is the commonest home (35.6%) and 31.3% of households rent privately. High Street ward is where the flats are: 37.7% of households live in purpose-built blocks and only 40.8% own. Park Wood and Shepway South have the town’s highest social-rented shares, 36.9% and 39.7%, so for more than a third of households there, a housing association or the council has the final say on the roof.
Pre-1919 roofs in Fant and the centre, post-war estates to the south-east
On the Valuation Office Agency’s count, about 7,310 of the town’s 43,430 council-tax properties, some 16.8%, were built before 1919, a little under the borough’s 17.2%. They sit west of the Medway and around the centre: Fant leads at about 36%, then High Street ward at 31%, East at 28%, Bridge at 24% and North at 21%. Allington, Shepway North, Park Wood and Shepway South have almost none, and across the town the largest band, about 26.7%, dates from 1945 to 1972. Age is no bar to panels, but roof-mounted arrays normally come under building regulations, which the Planning Portal says includes checking the roof can carry the weight, so on a pre-1919 roof in Fant or East ward the rafters are assessed before any layout is fixed.
Six conservation areas and a listed town centre
Maidstone Borough Council, the planning authority, has six conservation areas in the town itself: Maidstone Town Centre, All Saints Church, Ashford Road, Chillington House, Holy Trinity Church and Rocky Hill, with Loose Valley and Grove Green on the edge. Plotted against the council’s boundaries, Historic England’s list puts around 99 entries inside the Town Centre area, 89 Grade II and 9 Grade II*, and 16 in the All Saints Church area, four of them Grade I.
In all six, panels on a house’s pitched roof, street-facing slope included, stay permitted development within the 0.2 m and roof-height limits, unless an Article 4 direction removes the right. The designation rules out a wall, balcony or roof enclosure fronting a highway, and a flat roof in any of them needs the council’s prior approval. A listed house in any of them gets no permitted development for panels, so it needs planning permission and possibly listed building consent. Our guide to planning permission for solar panels in Kent covers the limits, which changed on 27 August 2026, and how to check a Maidstone address for listing or an Article 4 direction.
South Eastern Power Networks and the G98 line
The Elexon grid supply point group for ME14 1AA is _J, so UK Power Networks runs Maidstone’s local network under its South Eastern Power Networks (SPN) licence. If a Maidstone house’s panels and any battery together total 16 A per phase or less, about 3.68 kW on a single-phase supply, UK Power Networks is notified under G98 within 28 days of commissioning; above that, a G99 application goes in before installation. A battery’s inverter counts towards that total alongside the panels’, and each of our guide-priced systems pairs the panels with 10 kWh of battery capacity, so the combined inverter rating, not the number of panels, decides the route. The G98 notification or G99 application to SPN is included as standard in every install.
21.8 miles from Keston
Maidstone is the furthest of our 13 towns, 21.8 miles in a straight line from our office at Glebe Farm Business Park, Keston, and further by road. The solar panels we design and install are fitted by our own qualified electricians. TrustMark’s register (licence 2677315) lists our solar PV trade as MCS-certified, with NICEIC as scheme provider, and we are members of the Renewable Energy Consumer Code (00072268) and Which? Trusted Traders.
Maidstone Borough is missing from the government’s Warm Homes: Local Grant list, updated 2 July 2026, so for most households here the help is 0% VAT on panels fitted in homes until 31 March 2027, then 5%, plus Smart Export Guarantee payments, which need an MCS-certified installation. Solar panel grants in Kent sets out each route. If a pre-1919 house in Fant or East ward needs its consumer unit or wiring looked at before the panels go on, start with our page for an electrician in Maidstone.

02 Questions from Maidstone
Solar panels,
answered for Maidstone.
Do I need planning permission for solar panels on a house in a Maidstone conservation area?
Usually not, unless the house is listed or an Article 4 direction removes the right. Inside the Town Centre, Rocky Hill, Holy Trinity Church or any other of the town's six conservation areas, panels on a pitched roof stay permitted development, street-facing slope included, if they sit within 0.2 m of the slope and below the roof's highest point. Walls, balconies and roof enclosures fronting a highway are excluded, and a flat roof needs the council's prior approval first. A listed house needs planning permission from Maidstone Borough Council, so check the listing first.
I own a flat off Maidstone High Street. Can I have solar panels?
Not on your own say-so. In High Street ward 37.7% of households live in purpose-built blocks, where the roof is shared and, the Planning Portal says, leaseholders may need permission from the freeholder, landlord or management company. Blocks of flats also have their own permitted development limits. Another 2.6% of the ward's households live in a flat inside a commercial building, such as above a shop; that building isn't made wholly of flats, so ask Maidstone Borough Council which rules apply.
Is there a grant for solar panels in Maidstone?
Not for most households. Maidstone Borough isn't on the government's Warm Homes: Local Grant list, updated 2 July 2026. ECO4, which ends on 31 December 2026, funds solar only for eligible low-income households, and only alongside qualifying electric heating; 11.0% of the town's households heat with electricity alone, rising to 26.2% in Bridge ward, though not every electric system qualifies. Switch Together Kent covers Maidstone, but it is group buying, and no round was open on 15 October 2026. Panels installed in homes carry 0% VAT until 31 March 2027, then 5%.
My Fant terrace is over 100 years old. Will the roof take panels?
Age alone doesn't rule them out. The Valuation Office Agency dates about 36% of Fant's properties to before 1919, the highest share of any ward in the town. Roof-mounted panels normally come under building regulations, which the Planning Portal says includes checking that the roof can carry the added weight, so an old roof's structure is assessed before a layout is settled. On a terrace, neighbouring chimneys and roofs can shade the array too, and the 4,227 kWh figure assumes no shade at all.
