Scaffolding for Solar Panels in London: Licences, Access and Timings

Most solar installations on London homes need scaffolding, because work on a pitched roof needs proper protection against falls. Where the scaffold stands on a pavement or road, the council (or Transport for London on red routes) has to license it first. On terraces, the alternative is often access through the back garden. Your installer should sort out the scaffold and any licence as part of the job, but it can affect when work can start.

Key points

• HSE guidance says work on sloping roofs needs scaffolding to prevent falls, with edge protection at the eaves and to the rear of terraced properties.

• A scaffold on the public highway needs a licence from the local highway authority, usually your borough council.

• On red routes, permission comes from Transport for London instead of the council.

• Councils set their own notice periods and minimum licence periods, so timings vary across London.

• Rear access through your own or a neighbour’s garden can avoid the pavement, but needs agreement and space.

Why scaffolding is needed

Fitting solar means carrying panels and rails onto a roof and working at the edge for a day or more. The HSE treats roof work as high risk and expects collective protection, such as scaffolding with guard rails, before relying on personal equipment like harnesses. For sloping roofs, its guidance is scaffolding to prevent falls, with edge protection at the eaves. It also expects scaffolds to be inspected before first use, at least every seven days, and after bad weather.

Ladders on their own aren’t a safe way to install solar. A quote that assumes no access equipment on a pitched roof is worth questioning.

Pavement scaffolds and licences

If the scaffold stands on the pavement or road in front of your house, it is on the public highway and needs a licence from the highway authority under the Highways Act 1980.

• Borough roads: the licence comes from your council’s highways or licensing team.

• Red routes: TfL controls these. Wandsworth Council, for example, states it can’t license scaffolds on red routes and that permission must come from TfL.

• Notice: councils publish their own lead times. Wandsworth asks for applications at least five working days before the licence starts; other boroughs differ.

• Minimum period: some councils set a minimum licence period. In Wandsworth it is 28 days, even if the scaffold is up for less.

• Conditions: councils typically require public liability insurance, lighting and protection for pedestrians, such as a covered walkway and clear footway width.

The scaffolding contractor or your installer normally makes the application. If parking bays need suspending for the scaffold lorry or the scaffold itself, that is a separate request to the council.

Rear access on terraces

On many London terraces, the solar panels go on the rear roof slope or the back extension, which is often better for sun and keeps the front of the house unchanged. In that case the scaffold may go up in the back garden instead of on the pavement.

• Access matters: scaffold tubes and boards have to get to the garden, through the house, a side passage or a rear access lane.

• If the scaffold needs to stand on a neighbour’s land or be carried through their property, you’ll need their agreement.

• A rear scaffold avoids a highway licence when it is entirely on private land.

Other access options

Scaffolding isn’t the only form of edge protection, but it is the most common for domestic solar. On some low roofs, flat roofs or rear extensions, a smaller scaffold or roof-edge protection system may be enough. Our guide to solar panels on flat roofs and rear extensions covers those jobs. The right method depends on a risk assessment for your roof, not a one-size rule.

How it affects your installation date

The scaffold is usually the first thing to go up and the last to come down. Typical steps are:

1. The survey identifies where the scaffold will go and whether a licence is needed.

2. The licence is applied for, with the council’s notice period built in.

3. The scaffold goes up shortly before installation day.

4. The panels and electrical work are installed.

5. The scaffold comes down once the job is signed off.

Licence lead times, the scaffolding contractor’s availability and the weather can all move dates. Our guide to the solar installation process step by step explains how the rest of the job fits around it.

Doing roof work at the same time

If your roof needs repairs, use the same scaffold. Doing roof work before solar avoids having to take the panels off later. Our guides to whether you need a new roof before solar and removing solar panels for roof repairs explain why, and our roofing team can do both under one job.

Frequently asked questions

Do I need to apply for the scaffold licence myself?

Usually not. The scaffolding contractor or your installer normally applies, but check who is responsible when you accept a quote.

Can solar be installed without scaffolding?

On a pitched roof, safe installation needs proper edge protection, which in practice usually means scaffolding. Some low or flat roofs can use other methods after a risk assessment.

Will the scaffold block the pavement?

Licensed pavement scaffolds have to leave a safe route for pedestrians, often with a covered walkway. The council sets the conditions.

Does the scaffold affect my neighbours?

It can, especially on terraces. Your installer should tell neighbours when the scaffold is going up, and get permission if it needs their land.
