Planning Permission & Legal Requirements
Understanding the legal requirements for demolition is crucial before starting your project. Here's what you need to know:
Prior Notification (Most Common)
For most residential demolitions, you need to submit a Prior Notificationto your local planning authority at least 6 weeks before demolition begins. This is not planning permission, but it allows the council to assess the proposed method of demolition and any necessary conditions.
- • Cost: Typically £96 (varies by council)
- • Timeframe: Submit 6 weeks before planned start
- • Response: Council has 28 days to respond with conditions
When You Need Full Planning Permission
Listed Buildings
Listed Building Consent is required for any demolition of a Listed Building or structures within its curtilage. This is a criminal offence without consent.
Conservation Areas
Buildings in Conservation Areas require planning permission for demolition if they exceed 115 cubic metres or are over 1,000 cubic metres total volume.
Replacement Dwellings
If you're demolishing to build a new property, you'll likely need planning permission for the new build, which may include conditions about demolition.
Other Legal Requirements
- Party Wall Act: If demolition affects shared walls, you must serve notice on neighbours under the Party Wall etc. Act 1996
- Asbestos Regulations: A Refurbishment and Demolition Survey is legally required before any demolition work
- CDM Regulations: Construction (Design and Management) Regulations 2015 apply to most demolition projects
The Demolition Process
Professional residential demolition follows a structured process to ensure safety, compliance, and efficiency. Here's what to expect:
Initial Survey & Quote
A site visit to assess the property, access, construction type, and any potential complications. This allows for an accurate, detailed quotation.
Typically 1-2 days
Asbestos Survey
A Refurbishment and Demolition Survey by a qualified surveyor is legally required. This identifies any asbestos-containing materials that need specialist removal.
Survey: 1 day | Results: 3-5 days
Permissions & Notifications
Submit Prior Notification to the council, serve Party Wall notices if required, and arrange utility disconnections (gas, electric, water, telecoms).
Allow 6-8 weeks
Soft Strip & Preparation
Removal of internal fittings, fixtures, and non-structural elements. This includes kitchens, bathrooms, doors, windows, and any items for salvage or recycling.
1-3 days depending on size
Structural Demolition
Controlled demolition of the main structure using excavators and specialist attachments. This is done methodically from top to bottom, with careful attention to safety and dust suppression.
1-5 days depending on size
Site Clearance & Completion
Removal of all rubble, foundations (if required), and debris. Materials are sorted for recycling, and the site is left clean and ready for its next use. Waste transfer notes are provided for all materials.
1-3 days
Project Timeline
A typical residential demolition project takes 4-8 weeks from initial enquiry to completion. Here's a realistic timeline breakdown:

Frequently Asked Questions
How much does it cost to demolish a house in the UK?
House demolition costs vary significantly depending on size, location, access, construction type, and materials. Every project is unique, which is why we provide free, no-obligation quotes tailored to your specific requirements. Contact us for an accurate price for your project.
Do I need planning permission to demolish a house?
For most residential demolitions, you don't need full planning permission but must submit a Prior Notification to your local council at least 6 weeks before demolition begins. However, buildings in Conservation Areas, Listed Buildings, or demolitions requiring a new build will have different requirements.
How long does it take to demolish a house?
The actual demolition of a typical house takes 3-7 days. However, the complete process including site surveys, asbestos testing, utility disconnection, obtaining permits, and site clearance can take 4-8 weeks from initial enquiry to completion.
What happens to materials after demolition?
Professional demolition contractors recycle up to 90% of demolition materials. Concrete and brick are crushed for aggregate, metals are recycled, timber can be repurposed or used for biomass, and only non-recyclable waste goes to landfill. You should receive waste transfer notes for all materials.
Can I live next door during demolition?
Yes, in most cases neighbouring properties can remain occupied. Professional contractors use dust suppression, safety barriers, and work during reasonable hours to minimise disruption. Party wall agreements may include protection measures for adjoining properties.
