Which Council Decides on Your Solar Panels?Waterlooville, Berewood, Denmead, Clanfield and Horndean
Within a few miles of Waterlooville town centre, a solar question can land on four different planning authorities. For most homes the answer is still that no application is needed — but the details that can change it depend on who covers your address.
- Most of Waterlooville: Havant Borough Council
- Berewood: split between Havant Borough Council and Winchester City Council
- Denmead: Winchester City Council
- Clanfield and Horndean: East Hampshire District Council, except land inside the South Downs National Park
- Roof-mounted panels on a house are usually permitted development under all of them
Four Authorities Within a Few Miles
Waterlooville sits where Havant borough meets the City of Winchester district and East Hampshire, with the South Downs National Park just to the north. Which of them handles a planning question depends on the address, not the town name.
| Place | Planning authority | Worth knowing |
|---|---|---|
| Waterlooville, Cowplain, Purbrook | Havant Borough Council | Covers most of the town |
| Berewood (West of Waterlooville) | Havant Borough Council and Winchester City Council | Cross-boundary scheme for at least 2,550 homes |
| Denmead | Winchester City Council | A parish in the City of Winchester district |
| Clanfield, Horndean | East Hampshire District Council | For land outside the National Park |
| Land inside the South Downs National Park | South Downs National Park Authority | Includes parts of Horndean parish |

What Is the Same Everywhere: Permitted Development
Whichever council covers you, the national rules for a house are the same. Under Part 14 of the permitted development order, as amended on 27 August 2026, roof-mounted panels do not need planning permission if they project no more than 0.2 m from the roof slope, sit no higher than the highest part of the roof (chimneys excluded), and are sited, so far as practicable, to minimise their effect on the building’s appearance.
In a conservation area, panels on a wall, balcony or roof enclosure fronting a highway are not permitted development; roof slopes are not restricted. Listed buildings fall outside the rules entirely, so they need listed building consent. And any council can use an Article 4 direction to withdraw permitted development rights on particular properties — which is why the authority matters even when the national rules do not change.
When the National Park Makes a Difference
National Park land is “article 2(3)” land. A flat-roof array there — like one in a conservation area — needs a prior approval application before work starts, and the National Park Authority applies its own design policies to anything that does need permission. Roof-slope panels on a house remain permitted development within the same limits.
East Hampshire District Council’s Local Plan covers Clanfield outside the National Park, but the Park boundary runs close to the village and through Horndean parish, so check your exact address. Further into the Park, our page on solar panels in Petersfield covers a town inside it.
New-Build Estates: Covenants Before Councils
On Berewood and other new estates, the first obstacle is more often the paperwork than the planning. Check your deeds and any estate management company rules for restrictions on external additions, and check what the builder’s warranty says about roof work.
Then check what is already there. New homes built to the 2021 edition of Part L of the Building Regulations, in force from 15 June 2022, often have a small solar array. A battery can usually be added on the AC side without replacing a working inverter; extra panels may need a new notification to, or approval from, SSEN, the local network operator.
How to Check in Five Minutes
1. Find your council from your postcode with GOV.UK’s “Find your local council” service. 2. If you are north of the town, check the South Downs National Park boundary for your address. 3. Check whether your home is listed on Historic England’s National Heritage List, and whether it is in a conservation area. 4. Ask the council whether an Article 4 direction applies to your street. 5. On a new estate, read your deeds and the management company rules.

Frequently Asked Questions
Do I need planning permission for solar panels in Waterlooville?
Usually not. Roof-mounted panels on a house are permitted development if they project no more than 0.2 m and sit no higher than the highest part of the roof. Listed buildings, flat-roof arrays on protected land and homes covered by an Article 4 direction are the exceptions.
Is Clanfield in the South Downs National Park?
East Hampshire District Council’s Local Plan covers Clanfield outside the National Park, but the boundary runs close to the village and through Horndean parish, so check your exact address.
Who decides planning in Denmead?
Winchester City Council. Denmead is a parish in the City of Winchester district, even though it sits beside Waterlooville.
Can my estate management company stop me installing solar panels?
It can if your deeds or the estate rules restrict external additions, whatever the planning position. Check both before you commit to a design.
