Planning a strip-out, a full demolition, or a site clearance and trying to work out what it’ll actually cost? Commercial demolition cost typically runs £40-£150 per square metre for full structural demolition including foundations, and £15-£50 per m² for soft strip or internal strip-out work only – with London and the South East usually sitting at the higher end due to labour, access and disposal costs.
House demolition tends to price differently again, generally £80-£115 per m², because domestic sites are smaller but often have tighter access and more hand-demolition work involved.
As a demolition contractor with over 25 years’ experience across London, Lincolnshire and the wider Eastern England region, we get asked for a “per square metre” figure more than anything else – but demolition pricing genuinely depends on what’s found on site, so treat the numbers below as a planning benchmark rather than a fixed quote.
Key Takeaways
- Full commercial demolition typically cost £40-£150 per m², while soft strip/internal strip-out alone is considerably cheaper at £15-£50 per m².
- House demolition often costs more per m² than commercial full demolition (£80-£115 per m²), mainly due to tighter access and a higher proportion of hand-demolition work.
- Asbestos, site access, waste disposal method, and utilities disconnection are the four things that consistently move a demolition quote up or down from the headline figures.
Commercial Demolition Cost By Scope
| Scope of work | Approx. cost per m² |
| Soft strip / internal strip-out only | £15–£50 |
| Full structural demolition (incl. foundations) | £40–£150 |
| London and South East | Typically at the higher end of both ranges above |
Full commercial demolition cost – breaking down the structure and removing foundations – generally runs £40 to £150 per square metre.
Soft strip or internal strip-out work, meaning removing fixtures, partitions and services without touching the structural shell, is considerably cheaper at £15-£50 per square metre.
Where a project sits in that range depends heavily on the building’s construction (steel frame vs masonry vs reinforced concrete), site access for machinery, and how much material can be crushed and reused on site versus removed for disposal.
House Demolition Cost
Residential demolition is usually priced differently, since houses tend to be smaller and simpler structures than commercial buildings, but disposal, access and party-wall considerations still matter just as much.
| Property size | Typical cost |
| Small detached house (80–120m²) | Around £7,500 average |
| Large detached house (200–250m²) | Around £20,000 average |
| Overall range across sizes/locations | £6,400–£24,380 |
| Cost per m² | £80–£115 |
House demolition costs per square metre are often higher than commercial full demolition, mainly because domestic sites frequently have tighter access, closer proximity to neighbouring properties, and a higher proportion of hand-demolition work required as a result.
A detached house on a wide plot with clear machine access can come in well below these figures; a terraced or semi-detached property sandwiched between neighbours generally costs more, because slower, careful hand demolition replaces a lot of the faster machine work.
What Actually Drives The Final Price
The headline per-m² figures above are a useful starting point, but four things consistently move a demolition quote up or down on real projects.
Asbestos And Hazardous Materials
Any building constructed or refurbished before 2000 needs an asbestos survey before demolition can legally proceed. Removal of confirmed asbestos-containing materials adds a separate, often substantial cost on top of the demolition itself – and it’s not something you can skip or estimate around, since it’s a legal requirement.
Access And Site Constraints
Urban sites, shared boundaries, overhead services or restricted vehicle access all slow down machinery-based demolition and push more of the work toward slower, costlier hand methods. A site with a wide, clear approach for excavators is a completely different pricing proposition to a building squeezed between two others on a narrow street.
Waste Disposal And Material Recovery
Crushing and reusing concrete on site – as sub-base material for a new build, for example – is considerably cheaper than removing all waste for landfill or recycling off-site. A good contractor factors this into the quote from the outset, since it can meaningfully change the final number either way.
Utilities Disconnection
Gas, water, electricity and telecoms all need to be safely disconnected and capped before demolition starts. Coordinating this with utility companies can affect both cost and project timeline – utility companies don’t always move at the pace a demolition schedule would like.
Full Demolition Vs Soft Strip: Which Do You Need?
Not every project needs the structural shell taken down. A soft strip or internal strip-out – removing fixtures, fittings, partitions, services and finishes while leaving the building’s structure standing – is common where a building is being refurbished rather than replaced, or ahead of a full demolition to reduce the amount of mixed waste later.
Full structural demolition is the right call where the building itself is coming down, whether for redevelopment, safety reasons, or because refurbishment genuinely isn’t viable.
Getting this distinction wrong at the quoting stage is one of the most common reasons demolition estimates end up miles apart from each other – always be clear with your contractor about exactly what scope you need before comparing prices.
Getting An Accurate Demolition Quote
Because so much of the final cost depends on what’s actually inside and underneath a building, a genuinely accurate quote requires a site visit, a review of any existing structural or asbestos surveys, and – for anything beyond a small residential structure – method statements covering access, waste disposal and safety.
Be wary of any demolition quote given without a site visit; it’s almost never accurate once work is actually underway.

Frequently Asked Questions
Do I need planning permission to demolish a building?
Demolition counts as “development” under UK planning law, but in England most whole-building demolitions can proceed under permitted development rights, provided a Prior Approval application is submitted to the local planning authority first. This triggers a 28-day process where the council decides whether to approve your proposed method of demolition and site restoration – it isn’t full planning permission, but it isn’t optional either. Conservation areas and listed buildings have stricter rules and generally do require a full planning or listed building consent application.
How long does a demolition project take?
A small residential demolition can often be completed within a few days once asbestos surveys, utility disconnections and site setup are done. Larger commercial demolitions can take anywhere from a few weeks to several months, depending on the building’s size, structural complexity, and how much material needs to be crushed, sorted or removed from site.
What happens to the waste and materials after demolition?
Concrete and masonry are frequently crushed on site and reused as sub-base material for the new build, which reduces both cost and environmental impact compared with sending everything to landfill. Metals are typically separated out and recycled, while any hazardous materials such as asbestos are removed and disposed of through licensed specialist routes, kept entirely separate from general demolition waste.
Why is house demolition sometimes more expensive per m² than commercial demolition?
It comes down to access and proximity. Commercial sites are often larger with clearer access for heavy machinery, which speeds up the work. Domestic properties, particularly terraced or semi-detached homes, often require careful hand demolition near shared boundaries, which takes longer and costs more per square metre even though the overall job is smaller.
Does every demolition project need an asbestos survey?
Any building built or refurbished before 2000 needs one before demolition can legally proceed – this isn’t optional, and a reputable contractor won’t start work without it. Buildings constructed entirely after 2000 are less likely to contain asbestos, but a survey is still standard practice to confirm this rather than assume it.
Is it cheaper to get one demolition quote or several?
Getting two or three quotes is generally worth doing, provided each one follows a proper site visit rather than a desk-based estimate. Compare not just the headline price but what’s actually included – asbestos survey, waste disposal method, utilities disconnection – since these are the details that most often separate an accurate quote from one that changes significantly once work starts.
