The short version
Tenants need the landlord’s agreement, and flat owners usually need the building owner’s too, because the roof is rarely theirs alone. As amended in August 2026, national rules let blocks of flats take panels without planning permission within limits, but not listed blocks. Private tenants can apply for the Warm Homes: Local Grant with their landlord’s agreement.
Who rents and who lives in flats
The three wards that carry the Northwich name have a very different mix of homes from the borough as a whole. The 2021 Census figures below are shares of households.
| Area | Households | Owned | Private rented | Social rented | Terraced | Flats |
|---|---|---|---|---|---|---|
| Northwich Leftwich | 2,279 | 55.9% | 16.7% | 25.8% | 27.1% | 21.3% |
| Northwich Winnington & Castle | 4,065 | 70.4% | 20.8% | 7.5% | 31.3% | 12.7% |
| Northwich Witton | 2,336 | 53.0% | 29.1% | 16.9% | 44.7% | 11.9% |
| Cheshire West and Chester | 155,154 | 68.3% | – | – | 20.6% | 11.9% |
In Witton, 29.1% of households rent privately and 44.7% live in terraced houses, so a typical solar enquiry there may well come from a tenant in a terrace. In Leftwich, 25.8% rent from a social landlord and 21.3% live in flats, against 11.9% across the borough. For many households in these wards, solar is a conversation with somebody else before it is a purchase.
Whose decision is it?
Private tenants
If you rent privately, the building belongs to your landlord, and fixing anything to its roof or walls needs the landlord’s written agreement. The practical route is a short written proposal: what you would like, who would pay, what happens to the panels and the paperwork if you move, and whether a scheme might cover some of the cost. A landlord who sees a tidy proposal is more likely to engage than one approached with a salesperson’s quote.
Social tenants
Council and housing association tenants are in the same position, except that the landlord is an organisation. Decisions on solar for social housing are often taken across many properties at once, as part of the landlord’s own plans for its homes. Ask your housing officer whether panels are planned for your property or block, and how tenants are consulted. This guide does not name or speak for any social landlord.
Leaseholders in flats
Owning a flat on a long lease usually means owning the inside of the flat, not the roof, the outside walls or the structure. Those normally belong to whoever owns the building, and the lease sets out what leaseholders may and may not do. Panels on a shared roof also affect every other flat, so the building owner, any management company and often the other leaseholders all have an interest. Read the lease, then put the question to the building owner or managing agent.
Landlords
If you own a Northwich house that you let, the decision is yours, but the tenant’s situation can affect which route makes sense. A tenant household that meets the income rules may open up the Warm Homes: Local Grant for the property, with conditions for landlords explained in grants and schemes.
Neighbours on a terrace
A terrace adds another party to the conversation even when the house itself is not shared. Scaffolding for a mid-terrace roof often has to stand in front of, or reach over, the houses either side, and that needs the neighbours’ agreement. The roof line is shared too, so a neighbour may notice slipped slates or disturbed flashing at the party wall before you do. A landlord weighing up panels on a Witton terrace will want to know that access has been agreed before work is booked.
The rules for blocks of flats
Planning law and permission from the owner are two different things. Permitted development, granted nationally by Part 14 of the GPDO, decides whether a planning application is needed. It never gives a tenant or leaseholder the right to fix anything to a building they do not own. With that understood, the order as amended by SI 2026/896 from 27 August 2026 sets these limits for a block of flats:
- Roofs. Panels on a roof slope must stand no more than 0.2 m out from the slope and stay below the highest part of the roof.
- Walls. Panels on a wall of the block must sit within 0.2 m of the wall’s surface.
- Conservation areas. For a block, the exclusion the order names is walls that front a road. Flat roofs on conservation-area land need the council to decide on prior approval first.
- Listed blocks. Permitted development does not apply. Panels need planning permission and Listed Building Consent.
Further conditions apply, so a building owner planning panels should read Part 14 in full or ask the council. To check whether a block is listed, search the National Heritage List for England; the conservation areas near the town are covered in conservation areas.
Plug-in solar
Plug-in solar means a small panel kit, usually hung on a balcony rail or a wall, that connects to the home through a socket rather than being wired in as a fixed installation. Under the amended order, plug-in solar counts as solar PV for planning purposes, so the same permitted development rules apply to it. There is one firm limit: the rights never cover plug-in panels fixed to timber walls, timber balconies, timber enclosures or timber-clad parts of a building.
That limit has particular meaning in a town where timber framing is part of the street scene. The listed buildings on Witton Street that were designed to be lifted if the ground sank are the best-known examples, and their story is in liftable timber buildings. If your balcony or wall is timber or clad in timber, plug-in panels fall outside permitted development there.
This guide covers only the planning side. Electrical safety and product standards for plug-in kits are a separate matter, and a tenant or leaseholder still needs the owner’s agreement before attaching anything to the building.
Private tenants and the Warm Homes: Local Grant
Private tenants are one of the groups the Warm Homes: Local Grant can help, with the landlord’s agreement. The home must be rated EPC D to G and the household must meet one of the income routes. Landlords must contribute at least half of the cost for each property after their first. Applications start on GOV.UK, and the council’s support schemes page explains who handles enquiries locally. With so many Witton households renting privately, this is the route most likely to matter on rented terraces there.
Who gets the value of the electricity?
On a rented house with panels, the tenant who pays the electricity bill benefits automatically from units used in the home, whoever paid for the panels. Exports are different. An export tariff is a contract with an electricity supplier, normally in the name of the account holder, and it needs the installation’s MCS certificate. Agree in writing who will sign up for it and who keeps what it pays, and make sure the tenant has a copy of the certificate. How exports and self-use work is explained in export and self-use.
A conversation plan for tenants and leaseholders
- Read your tenancy agreement or lease for anything about alterations, the roof or the external walls.
- Check whether the building is listed or in a conservation area.
- Put the idea in writing to the landlord or building owner, saying what you propose and who would pay.
- If you are a private tenant who may qualify for the Local Grant, say so, because it changes the landlord’s sums.
- Agree in writing what happens to the panels, the paperwork and the export tariff if you move out.
- Make sure any firm used is certified under MCS and chosen with the checks in choosing an installer.
Moving on
Panels belong with the building, not with whoever asked for them. When a tenant leaves, the landlord keeps the panels and the paperwork, and the export tariff in the tenant’s name ends with their account. When a leaseholder sells, the buyer’s solicitor will want to see that the building owner consented to the panels and that the certificates are in order. What a buyer should ask for is set out in buying a Northwich home with solar.
This page summarises planning rules and scheme criteria; it is not legal advice on any tenancy or lease. Your agreement, the building owner’s consent and the council’s view are what decide whether panels can go up.
