Thinking of upgrading your home with timber cladding? It’s an excellent way to enhance kerb appeal, boost insulation, and add natural character—but before you begin, it’s important to ask:

Do I need planning permission to install timber cladding on my home in the UK?

In most cases, the answer is no—but there are important exceptions. In this guide, we break down everything you need to know, from Permitted Development rights to building regulations, conservation areas, and the best timber species to choose.

What Is Permitted Development?

Permitted Development (PD) rights in the UK allow homeowners to make certain changes to their property without needing formal planning permission. This includes installing external timber cladding, provided specific conditions are met.

Timber Cladding Is Usually Allowed If:

Your home is not a listed building
It’s not in a Conservation Area or Area of Outstanding Natural Beauty (AONB)
The cladding material is of a similar appearance to existing finishes (this is somewhat open to interpretation)

For many standard residential properties, timber cladding is allowed under PD and won’t require full planning approval.

When You Do Need Planning Permission

Certain types of properties and locations fall outside of Permitted Development. You’ll need to apply for planning permission if:

1. You Live in a Listed Building

Any external change—no matter how minor—requires Listed Building Consent, even if the timber cladding is designed to be sympathetic or reversible.

2. You’re in a Conservation Area or AONB

These designations aim to protect historical or rural character. Cladding may be restricted or refused, especially if it changes the building’s appearance significantly.

3. You Live in a Flat or Maisonette

Permitted Development rights do not apply to flats. Any cladding work will require full planning permission.

4. You're Converting a Building (e.g. Barn or Office)

Conversions under Class Q or other change-of-use classes often need prior approval, and timber cladding may require separate approval, especially if it's not part of the original structure.

Don’t Forget Building Regulations

Planning permission is not the same as Building Regulations. Even if you don’t need planning permission, your cladding must still meet certain technical requirements.

Key Regulations to Consider:

Approved Document B – Fire Safety

If your cladding is installed above 11 metres, it must meet Euroclass B-s1,d0 fire performance. Use fire-retardant-treated ThermoWood® or other compliant species to meet this standard.

Approved Document L – Energy Efficiency

If you’re upgrading external walls, you may need to improve insulation to meet energy efficiency targets.

Ventilation & Moisture Management

Ensure proper:

Battening and breathable membranes
Ventilation gaps
Drip detailing

Poor ventilation leads to moisture traps, causing timber decay and performance issues.

How to Check if You Need Permission

To avoid delays or legal issues, always do the following:

Step-by-Step:

Visit the UK Planning Portal: https://www.planningportal.co.uk
Contact Your Local Planning Authority (LPA):Especially important for listed buildings, conservation areas, or boundary disputes.
Check Your Property Deeds or Covenants:Some properties have additional restrictions from developers or estate agreements.

Check Before You Clad

For most UK homeowners, timber cladding is allowed without planning permission. But if your home is listed, in a conservation area, a flat, or being converted, it’s best to check with your local authority.

By choosing the right timber—like fire-rated ThermoWood®, Scottish Larch, Douglas Fir, or Western Red Cedar—and complying with fire and insulation regulations, you can achieve a beautiful, compliant, and long-lasting transformation.
