Do I need
planning permission
for a new roof?

The short answer

For most Worcestershire homeowners replacing a roof like-for-like, no planning permission is needed — it falls under permitted development rights. But you may need permission if:

• Your home is in a conservation area
• Your home is a listed building (Grade I, II* or II)
• You're changing the materials substantially (e.g. concrete tile to slate, or vice versa)
• You're changing the roof shape or pitch
• You're raising the roof line by more than 150mm
• You're adding dormers, skylights or roof extensions beyond permitted development limits

Each of these has nuances. Let's go through them properly.

1. Standard like-for-like replacement

If you're replacing your roof with the same material and approximate appearance — same colour, same profile, same pitch — you're almost certainly covered by permitted development rights. No application needed.

This applies to most ASH Roofing jobs: a 1970s concrete-tile semi being re-roofed in the same concrete tiles needs nothing from the council.

2. Conservation areas in Worcestershire

Worcestershire has dozens of conservation areas. Major ones include:

• Worcester — multiple conservation areas covering the cathedral district, riverside, and Georgian terraces
• Malvern — large conservation area covering Great Malvern, Malvern Wells, and parts of West Malvern
• Pershore — town centre conservation area
• Bewdley — historic riverside town
• Tenbury Wells — market town centre
• Droitwich Spa — Victorian spa-era core
• Many villages — including Bretforton, Hanley Swan, Cropthorne, Ombersley

In a conservation area, permitted development rights are reduced. A like-for-like replacement is usually still fine, but changing materials almost always needs permission. So if you have an original Welsh slate roof and want to replace it with concrete tiles to save money, you'll need consent from the local planning authority.

If you're not sure whether you're in a conservation area, you can check on your council's website:

• Worcester: worcester.gov.uk
• Malvern Hills District: malvernhills.gov.uk
• Wychavon (Evesham/Pershore/Droitwich): wychavon.gov.uk
• Wyre Forest (Kidderminster/Stourport/Bewdley): wyreforestdc.gov.uk
• Bromsgrove District: bromsgrove.gov.uk
• Redditch Borough: redditchbc.gov.uk

3. Listed buildings

If your home is listed (Grade I, II* or II), any external work — including roof replacement — almost always requires Listed Building Consent. This is separate from planning permission and is a more rigorous process.

Worcestershire has thousands of listed buildings — from medieval cottages to Victorian villas. To check if yours is listed, search the Historic England National Heritage List.

Working on a listed building without consent is a criminal offence under the Planning (Listed Buildings and Conservation Areas) Act 1990. Don't take shortcuts.

4. Building Regulations (separate from planning permission)

Even when you don't need planning permission, you may still need Building Regulations approval. These are separate things:

• Planning permission = is this work allowed in this location?
• Building Regs = is the work being done to safety and energy standards?

Most roof replacements need Building Regs sign-off. The roofer can usually arrange this through a Competent Person Scheme (CPS) — meaning they self-certify and register the work without you needing to involve building control directly.

5. Insulation requirements when re-roofing

Since 2010, Building Regs have required that when a significant proportion of the roof is being replaced, the insulation must be brought up to current standards if practical. The current target is U-value of 0.18 W/m²K or better.

On most older Worcestershire homes, this means adding insulation between or above the rafters during the re-roof. Budget around £1,500–£3,000 extra for proper insulation on a typical detached property — but the energy savings usually pay this back within 5–8 years.

6. Solar panels and the roof

Adding solar panels at the same time as a re-roof is generally permitted development as long as:

• Panels don't project more than 200mm beyond the roof plane
• They're not on a wall facing a highway in a conservation area
• They don't sit higher than the highest part of the roof (excluding chimneys)

On listed buildings, solar panel installation usually needs Listed Building Consent.

7. Adding dormers, skylights or roof lights

Skylights/Velux windows are usually permitted development if they don't project more than 150mm beyond the roof plane and aren't on a roof slope facing a highway.

Full dormer windows are different — they often need planning permission, especially in conservation areas. Talk to your roofer or to the planning department before committing.

How to get planning permission if you need it

If you do need permission, the process is:

1. Contact your local planning authority for pre-application advice (sometimes free, sometimes a small fee)
2. Submit your application through the Planning Portal — typically £258 for a householder application as of 2026
3. Wait 8 weeks for a decision (usual timeframe)
4. Make changes if requested by the planning officer
5. Receive decision — approval, refusal with reasons, or approval with conditions

For listed buildings, the Listed Building Consent process is similar but typically more detailed and slower.

Quick reference: do I need permission?

• Standard like-for-like re-roof, not in conservation area, not listed → NO permission needed
• Like-for-like re-roof in conservation area → Probably no permission needed, but check first
• Like-for-like re-roof on listed building → Yes — Listed Building Consent
• Material change (slate to concrete or vice versa), anywhere → Probably yes
• Adding dormers → Probably yes
• Just adding skylights → Usually no, unless listed/highway-facing
• Adding solar panels → Usually no, unless listed/highway-facing

When in doubt — phone your council's planning department before starting work. A 5-minute conversation can save you a lot of trouble.
