Demolition & Strip-Out Calculators

Demolition and strip-out work requires careful planning to manage costs, timelines, and regulatory compliance. Our calculators help you estimate skip hire volumes, waste tonnage, labour hours for soft strip operations, and overall demolition costs per square metre. Whether you're carrying out a full structural demolition or a selective interior strip-out, accurate estimating is essential for competitive pricing and profitable project delivery.

In the UK, demolition projects must comply with the CDM (Construction Design and Management) Regulations 2015, and larger works require a written demolition method statement in line with BS 6187:2011 (Code of Practice for Full and Partial Demolition). Asbestos surveys are a legal requirement before any refurbishment or demolition work under the Control of Asbestos Regulations 2012, and licensed contractors must handle any asbestos-containing materials found during strip-out.

These tools also cover waste management considerations including Site Waste Management Plans, duty of care requirements for waste transfer, and estimating landfill tax costs at current HMRC rates. Use them alongside your site surveys to produce accurate quotations that account for disposal fees, plant hire, and the labour-intensive nature of demolition and strip-out operations across residential, commercial, and industrial projects.

How much does demolition cost in the UK?

Demolition costs depend entirely on scope: a full kitchen strip-out typically runs £500–1,500 and a bathroom £300–800, while stripping a whole house back to bare walls costs roughly £3,000–8,000. Structural work costs more — removing an internal load-bearing wall with an RSJ is typically £1,200–2,500, and a ground-floor chimney breast removal £1,500–3,000 including propping, waste disposal and making good. Waste handling is a major cost driver: allow £200–400 per builder's skip, and £150–300 per tonne where asbestos must go to a licensed hazardous-waste landfill. Use the calculators above to price each element of your job separately.

What do demolition costs per m² depend on?

There is no single UK demolition rate per m² — contractors price from the waste tonnage, labour, plant and access that the specific structure generates. As a planning guide, full demolition of a typical masonry house produces roughly 0.5–1 tonne of waste per m² of floor area (timber-framed buildings around 0.3–0.5 tonnes/m²), and waste disposal — skips or roll-on/roll-off containers plus tipping fees — is one of the biggest cost drivers. Use the structural demolition calculator to estimate debris tonnage from your building's dimensions and construction type and to plan the top-down sequence and temporary support in line with BS 6187:2011, then the demolition waste calculator to convert waste volumes into skip or grab-lorry loads.
