The short answer
As a rough UK guide, demolition is often quoted at around £30 to £150 per square metre of building footprint, with simpler single-storey structures at the lower end and multi-storey, basement or heavily serviced buildings at the higher end. This rate is a sense-check, not a quote: most contractors price per job after a site visit, because two buildings of the same floor area can cost very differently depending on construction type, number of storeys, access for plant and skips, asbestos, and how far waste must be hauled. A per-square-metre figure also ignores fixed costs that do not scale neatly with area, such as service disconnections, surveys and site setup. Use the rate to gauge whether a quote is in the right ballpark, then rely on the itemised quote for the real number.
A per-square-metre rate is handy for early budgeting, but it hides as much as it reveals. People reach for it because it feels precise and comparable, yet demolition resists being reduced to a single rate more than most building work. Here is how to use it sensibly, and where it will mislead you if taken too literally.

Indicative per-square-metre ranges
The figures below give a feel for how the rate shifts with the type of structure. They are guidance only; the real price comes from a quote that accounts for the specific site.
| Building type | Indicative rate (per m²) | Why |
|---|---|---|
| Single-storey outbuilding | ~£30–£60 | Simple structure, low waste volume |
| Standard two-storey house | ~£60–£100 | More structure and waste per footprint |
| Building with basement | ~£100–£150+ | Deep excavation and backfill |
| Restricted-access site | Add to base rate | Hand demolition, slower work |

Why per-square-metre is only a guide
- Storeys, not just footprint: a two-storey house has roughly twice the structure of a single-storey one on the same footprint, so floor area alone understates the work.
- Construction type: a concrete-framed or steel-framed building is far more demanding to take down than timber or single-skin brick.
- Fixed costs: surveys, service disconnections, plant mobilisation and site setup are largely the same whether the building is small or medium, so they weigh more heavily on small jobs per square metre.
- Waste: tipping and haulage track the volume and type of material, not the floor area.
How contractors actually price
In practice, a UK demolition contractor builds a price from the parts of the job rather than multiplying area by a rate. The per-square-metre figure may appear nowhere in their working at all; it is something the customer applies afterwards as a check. They assess the structure and its condition, the likelihood and extent of asbestos, how plant and skips can be positioned, the disconnection of services, the volume and type of waste, and any party wall or notification requirements. The footprint informs the estimate but does not determine it. This is why a small house with an asbestos garage roof and no rear access can cost more per square metre than a larger, cleaner property on an open plot. The per-square-metre figure is most useful at the very start of budgeting, before a contractor has visited, and least useful once you have an itemised quote in front of you. It is the kind of number that helps you decide whether a project is worth pursuing at all, not the number you sign a contract against.
Using the rate without being misled
A per-square-metre figure earns its place as a quick gut-check, provided you remember what it leaves out. The most reliable way to use it is to convert it into a rough total, then test every real quote against that band and interrogate any large gap.
- Measure the footprint, then weight for storeys: a sensible early estimate multiplies the ground-floor footprint by the number of storeys before applying a rate, because the rate is really about volume of structure, not floor plan.
- Add the fixed items separately: surveys, service disconnections, mobilisation and waste are better estimated in their own right and added on top, rather than assumed to be inside the per-square-metre figure.
- Expect small jobs to look expensive per m²: the fixed costs spread across a small footprint inflate the apparent rate, which is normal and not a sign of overcharging.
- get the work priced up on inclusions, not rate: a lower headline rate that excludes foundation removal and waste is not cheaper than a higher one that includes them.
Used this way, the rate helps you spot a quote that is in the wrong ballpark and prompts the right questions, while the itemised quote remains the document you actually budget and decide from.
What the per-square-metre figure leaves out
It is worth being explicit about the costs a simple area calculation ignores, because these are exactly the items that cause a real quote to land above a naive per-square-metre estimate. None of them scale neatly with floor area, yet all of them are real parts of the job.
- Asbestos survey and removal: a refurbishment and demolition survey is needed for most older buildings, and any licensed asbestos is removed under separate regulated arrangements. This cost depends on what is present, not on the floor area.
- Service disconnections: gas, electricity and water are disconnected by the providers, with their own charges and lead times, regardless of how big the building is.
- Notifications and permits: demolition is usually notifiable to the local authority, and skip permits apply where skips stand on a public road. These are fixed procedural costs.
- Foundations and clearance: breaking out foundations and levelling a plot is driven by the depth and extent of the below-ground structure, which the footprint does not reveal.
- Mobilisation: getting plant and crew to and from the site is broadly the same cost whether the building is small or medium-sized.
Because these items are absent from a per-square-metre rate, the rate systematically understates the cost of small jobs, where the fixed costs loom largest, and can overstate the unit cost of large, simple buildings, where they spread thinly. That is not a flaw to correct so much as a limitation to remember. The figure earns its keep as an early sanity check; the itemised quote, which prices the survey, disconnections, waste, foundations and clearance in their own right, is what you actually plan and pay against. Treat the rate as the opening question and the quote as the answer.
Frequently asked questions
Why do contractors prefer to price per job?
Because access, construction type, asbestos and waste vary so much that floor area alone is a poor predictor of cost. A per-job price after a site visit captures these realities, which a flat per-square-metre rate cannot.
Does a basement change the per-square-metre cost?
Yes, significantly. A basement adds deep excavation, demolition below ground and backfilling, none of which is reflected in the above-ground footprint, so the effective rate per square metre rises.
Is a two-storey house double the cost of a single-storey one?
Roughly, the structure and waste are around double on the same footprint, but it is rarely exactly double once fixed costs, access and asbestos are factored in. Use it as a guide, not a precise multiplier.
