With energy bills still painfully high, more Kingston homeowners are looking at solar panels as a way to cut costs and reduce their carbon footprint. The technology is cheaper than it's ever been, and the government's permitted development rules — specifically Part 14 of the General Permitted Development Order (GPDO) — mean that most homes in England can install panels without a full planning application.
But Kingston upon Thames has a more complicated picture than many boroughs. Conservation areas, listed buildings, and proximity to the Thames all create situations where permitted development rights either don't apply or come with conditions that can trip you up — and trip up your installer.
This guide lays out what the rules actually mean for Kingston residents, where the local gotchas are, and what to check before you sign a contract.
Under Part 14, Class A of the GPDO, householders can install solar panels on a dwelling without applying for planning permission, provided the installation meets certain conditions. These include:
Crucially, these permitted development rights can be removed or restricted in specific circumstances — and several of those circumstances exist right here in Kingston.
Kingston upon Thames has a significant number of designated conservation areas, and this is where most planning complications arise for solar installations.
Kingston Town Centre Conservation Area covers large parts of the historic core, including streets near the ancient market square, Clarence Street, and down towards the riverside. If your property falls within this boundary, Class A permitted development for solar panels is restricted on walls and roof slopes that face a highway. In practice, this means any panel visible from a public road or footpath on the front elevation of your property will require a full planning application.
Surbiton has its own conservation area designations — particularly around the Victoria Road and Maple Road Victorian terraces — where the same restrictions apply. The neat rows of south-facing bay-windowed roofs that look perfect for solar are often precisely the ones where permitted development does not cover a front-facing installation.
Other conservation areas in the borough include parts of Ham, New Malden, Coombe, and Tolworth. If you are not certain whether your street falls within a conservation area boundary, Kingston Council's planning map (available via the council's online planning portal) will show you. Do not rely on your installer telling you — check it yourself first.
The key question to ask: Does any part of my proposed solar installation face a highway, and is my property within a conservation area? If both answers are yes, you almost certainly need planning permission.
Permitted development rights for solar panels do not apply at all to listed buildings. Full stop.
Kingston has a cluster of listed structures around the medieval market square — the Ancient Market Place and surrounding streets — as well as listed buildings scattered through the older residential parts of the borough. The Clattern Bridge, parts of the Guildhall, and a number of Georgian and Victorian properties in the town centre are all listed.
If your home is a listed building, or if it is within the curtilage of a listed building (which can include outbuildings and boundary walls), you will need Listed Building Consent in addition to any planning permission. Installing panels without it is a criminal offence, not just a planning breach.
Again: check the Historic England listed buildings register and Kingston's own heritage assets list before going anywhere near an installer's brochure.
Kingston sits alongside the Thames, and significant parts of the borough — including riverside properties in Kingston Town, Hampton Wick, and Ham — fall within Environment Agency Flood Zone 2 or Flood Zone 3.
Being in a flood zone does not automatically block a solar installation, but it introduces additional considerations. If your property has already been subject to a flood resilience or resistance retrofit, or if you are applying for planning permission (because permitted development doesn't apply for another reason), the council will expect you to demonstrate that the installation does not increase flood risk or interfere with any existing flood mitigation measures.
More practically: battery storage units, which many solar installations now include, need careful siting in flood-risk properties. Placing a battery in a basement or at ground-floor level in a Flood Zone 3 property could be a problem both technically and from a planning perspective if consent is required.
Check your flood zone status on the Environment Agency's flood map for planning before you proceed.
Before you book an installer or sign anything, work through this list:
1. Is your property a listed building? Check the Historic England register and Kingston's local list. If yes, stop — you need specialist advice and Listed Building Consent before anything else.
2. Is your property in a conservation area? Use Kingston Council's online planning map to confirm. If yes, go to question 3.
3. Does the proposed installation face a highway? If you are in a conservation area and any panels would be visible from a public road or footpath, you will need a planning application.
4. Is your property in a flood zone? Check the Environment Agency map. If yes, consider the siting of any battery storage carefully and seek planning advice if you are already applying for permission.
5. Has permitted development been removed by a condition? Some properties have had permitted development rights removed by a planning condition attached to a previous consent (this is called an Article 4 direction or a condition on a prior approval). Check the planning history for your address on Kingston's portal.
6. Does the installation meet the technical conditions? Confirm with your installer that panels will not protrude more than 200mm, will not exceed the roof height, and will be at least 1 metre from flat roof edges.
7. Do you need to notify the council? Even where permitted development applies, some local authorities request a prior approval or notification. Kingston does not currently require prior approval for Class A solar under Part 14, but confirm this has not changed before you proceed.
Installing without the required permission is a breach of planning control. The council can issue an enforcement notice requiring you to remove the installation at your own cost. With listed buildings, the consequences are more serious — it is a criminal matter.
More immediately, an unpermitted installation can complicate the sale of your home. Conveyancers routinely check planning compliance, and a solar array installed without consent in a conservation area is exactly the kind of thing that stalls or kills a sale.
Kingston's planning enforcement team can be slow — like most councils, resources are stretched — but that is not a reason to take the risk.
Kingston's planning pages on solar are not the clearest they could be. A dedicated, plain-English guide for residents on Part 14 and local restrictions — with the conservation area map prominently linked — would save homeowners significant time and prevent unnecessary breaches.
With the council facing a projected four-year budget gap of £18 million (per the Medium Term Financial Strategy 2026–2030), there is also a broader question: are Kingston's planning fees and enforcement resources sufficient to support residents trying to make environmentally beneficial improvements while navigating a genuinely complex local picture?
These are reasonable questions to put directly to your ward councillor.
Kingston has 48 councillors across 19 wards, with full council elections due on 7 May 2026. Your councillors are accountable to you on planning policy, conservation area management, and how the council communicates complex rules to residents.
If you have struggled to get clear answers about solar panels and planning in Kingston, or if you think the council's guidance needs to be clearer, use Council Clarity to message your ward councillors directly. It takes two minutes, and it is exactly the kind of specific, local question they should be answering.
