Step by step

What's Involved in Hiring a Demolition

Demolition work follows a careful process of assessment, planning and safe execution to bring down structures while managing waste and hazards responsibly.

1

Site survey and assessment

A demolition contractor visits your property to assess the structure, check for hazards like asbestos, and understand access constraints. They will confirm whether the work requires planning permission, building control notification or a Party Wall Agreement with neighbours.

2

Asbestos check

For any building constructed before 2000, an asbestos survey is legally required before demolition or major refurbishment. If asbestos is found, a licensed asbestos removal contractor must remove it safely before demolition can proceed. This is a separate cost.

3

Get quotes and arrange skip hire

The contractor provides a detailed quote covering labour, machinery, skip hire and disposal fees. For larger jobs, they may arrange multiple skips or use a grab lorry. Waste transfer notes must be provided to prove materials are disposed of legally.

4

Disconnect services and prepare the site

Before any demolition begins, gas, electricity and water supplies to the structure must be disconnected by the relevant utility companies. The site is made safe with barriers or hoarding if near a public area, and neighbours are notified.

5

Carry out the demolition

The structure is brought down methodically, usually working from the top down. Small domestic jobs like garage or shed removal are done by hand with sledgehammers and breakers. Larger jobs may require mini excavators. Materials are sorted on-site for recycling where possible.

6

Site clearance and making good

All debris is cleared and removed from site. Foundations or slabs may be broken up and removed depending on what is planned next. The area is left level and tidy, and any making good to adjacent walls or surfaces is completed.

Local insights

What Affects Demolition Contractor Costs in Cornwall?

The South West has a varied housing stock, from Georgian and Regency townhouses in cities like Bath to stone-built farmhouses, coastal cottages and modern estates across Somerset and Devon. Cornwall has a range of property types and ages that can affect the scope and cost of work, and many properties in the region feature older stonework, lime render and period details that require specialist attention. With a population of null, Cornwall is a area where demolition contractor costs are one of the most affordable areas. Older and rural properties tend to push prices higher due to access difficulties and the need for sympathetic materials — internal wall removal (non-load-bearing) here averages around £700.

The South West generally sits close to or slightly below the national average for trade costs, though popular areas like Bath and Exeter can be pricier. Labour rates in Cornwall are around 12% below the UK average. In Cornwall, local demand for demolition contractor services varies depending on the mix of residential and commercial properties in the area. Longer travel distances between jobs in rural parts of Cornwall and Dorset mean some tradespeople factor travel time into their quotes. With fewer tradespeople based locally, you may find slightly less choice, and it is worth booking ahead for larger jobs. Prices can still vary 30-50% between different tradespeople, so always compare.

What you pay for demolition contractor work in Cornwall depends on the job scope, property type and materials. Period properties with lime plaster, stone walls or listed building restrictions often need specialist approaches that cost more. Coastal properties in Dorset and Cornwall can face salt exposure and damp issues that add complexity. A typical garage demolition in Cornwall costs around £1,755, while full house strip-out ranges from £2,630 to £10,525. As a area that is one of the most affordable areas, Cornwall offers fair value for demolition contractor work compared to London and the South East.

When getting quotes in Cornwall, aim for at least three from different qualified professionals. In more rural parts of the South West, fewer tradespeople may be available locally, so book ahead for larger jobs. Ask each one to visit and assess the work rather than quoting over the phone. A good demolition contractor will check the existing conditions, flag any complications from older or period features, and give you a detailed cost breakdown. With fewer tradespeople based locally, you may find slightly less choice, and it is worth booking ahead for larger jobs. Be wary of quotes that seem significantly cheaper — they may be cutting corners on materials or quality. Always check qualifications, insurance and recent reviews before hiring.

Depending on the work involved, you may also need skip hire (£70–£175), scaffolding (£525–£1,230), or builder (£26,310–£70,160) in Cornwall.

Common questions

Frequently Asked Questions

Common questions about demolition contractor costs in Cornwall.

Do I need planning permission for demolition work?
Demolishing a building over 50 cubic metres requires prior notification to your local planning authority. Listed buildings and buildings in conservation areas need full planning permission before any demolition. Even for smaller structures, check with your council first as local rules vary.
What is the difference between demolition and a strip-out?
Demolition involves bringing down all or part of a structure. A strip-out removes the interior fittings, partitions, flooring and services while leaving the main structure intact. Strip-outs are common before office refurbishments, shop fit-outs or residential renovations.
How is demolition waste disposed of?
Reputable demolition contractors sort waste on-site for recycling. Concrete, brick, metal and timber can all be recycled. Hazardous materials like asbestos must be disposed of at licensed facilities. Your contractor should provide waste transfer notes proving proper disposal.
Do I need an asbestos survey before demolition?
Yes. Under the Control of Asbestos Regulations 2012, a refurbishment and demolition asbestos survey is legally required before any demolition or major refurbishment work on buildings built before 2000. Asbestos removal must be carried out by a licensed contractor and can add significant cost to the project.
Do I need a Party Wall Agreement for demolition?
If the demolition work is within 3 metres of a neighbouring property or involves a shared wall, you may need to serve a Party Wall Notice under the Party Wall etc. Act 1996. This gives your neighbours formal notice and protects both parties. A Party Wall surveyor typically charges £700-£1,500 per neighbour.
Can I demolish a garage or shed myself?
Small timber structures like sheds can be dismantled by a competent DIYer with basic tools. However, brick or block garages with concrete bases, structures with asbestos roofing, or anything near boundaries or services should be done by a professional. You also need to dispose of waste legally — fly-tipping carries fines of up to £50,000.
How is demolition priced — by the job or by the day?
Most domestic demolition work is priced as a fixed quote for the whole job, including labour, skip hire and disposal. Some contractors charge day rates for strip-out work (typically £250-£400 per day per labourer). Always get a written quote that confirms exactly what is included, especially skip and disposal costs.
What happens to the foundations after demolition?
It depends on what you plan to do with the space. If you are rebuilding, existing foundations may be reusable subject to a structural engineer's approval. If you want a clear, level area, the concrete base and footings will need breaking up and removing, which adds to the cost.
How do I find a reputable demolition contractor?
Check that the contractor holds the appropriate waste carrier licence from the Environment Agency and has public liability insurance. For jobs involving asbestos, they must hold an HSE licence for asbestos removal. Ask for waste transfer notes after the job to prove materials were disposed of legally.
How much does a demolition contractor cost in Cornwall in 2026?
Garage Demolition in Cornwall typically costs between £875 and £3,070, with the average being around £1,755. Prices vary depending on the scope of work, materials used, and the specific requirements of your property.
Are demolition contractor prices cheaper in Cornwall than London?
Yes. Cornwall demolition contractor costs are typically 12% below the national average, while London prices run around 24% above it. For garage demolition, you could save over £730 compared to the same job in London.
How do I find a good demolition contractor in Cornwall?
Get at least three quotes from different tradespeople, check recent reviews, and ask whether the quote includes VAT and everything you need. A detailed written quote that breaks down all costs is a good sign. Always check qualifications, insurance and recent reviews before hiring.
What affects demolition contractor prices in Cornwall?
The main factors are the scope and complexity of what you need, the options and products chosen, and local market rates. Cornwall rates are 12% below the national average. Getting multiple quotes is the best way to ensure a fair price.
Do demolition contractor prices include materials in Cornwall?
The prices shown on this page include all typical costs. However, when getting real quotes, always confirm what is and isn't included. Some tradespeople break out costs separately, while others give an all-in price. Ask for a detailed breakdown before agreeing to any work.
