Once asbestos is stripped out of a building it does not disappear — it becomes hazardous waste that has to be tracked, taxed and buried under some of the tightest disposal rules in the UK. At least 230,000 tonnes of asbestos-containing waste is estimated to reach landfill in England every year, almost all of it going into the ground because there is still no meaningful alternative at scale. This guide pulls together the numbers on where that waste ends up, what it legally costs to get rid of, and how much is dumped illegally, citing every figure to its source: the Environment Agency's Waste Data Interrogator and Hazardous Waste Interrogator, Defra's fly-tipping and waste statistics, HMRC's Landfill Tax rates, and GOV.UK disposal guidance.
It is written for the people who actually handle this waste stream — licensed removal contractors, skip-hire and waste firms, demolition and construction teams, and the environmental journalists reporting on illegal dumping — with the data period stated alongside every figure.
Key facts and figures
- At least 230,000 tonnes of asbestos-containing waste is estimated to be sent to landfill in England every year (widely cited sector estimate).
- £130.75 per tonne is the standard rate of Landfill Tax on asbestos from 1 April 2026, up from £126.15 in 2025 (HMRC).
- ~6,000 regulated sites are covered by the Environment Agency's Waste Data Interrogator, letting you compute exact asbestos (EWC 17 06*) tonnages per calendar year (EA, 2023 dataset).
- 1.26 million fly-tipping incidents were recorded in England in 2024/25, up 9% on the previous year (Defra, 2024/25).
- ~70,000 construction, demolition and excavation fly-tips in 2024/25 — up 12% year on year — the category carrying most illegally dumped asbestos (Defra, 2024/25).
- £19.3 million was spent clearing the largest fly-tips (tipper-lorry load or bigger) in England in 2024/25 (Defra, 2024/25).
- 45.0 million tonnes of UK waste went to landfill in 2020 — the disposal route asbestos is legally confined to (Defra, UK statistics on waste).
- 29,500 tonnes/year is the Environment Agency permit limit for the UK's leading asbestos thermal-treatment operator, so burial still dominates (Thermal Recycling / EA permit).
All figures are the latest available as of July 2026. The EA's Waste Data Interrogator and Hazardous Waste Interrogator release the prior calendar year each autumn, Defra's fly-tipping statistics come out each spring, and HMRC resets Landfill Tax rates every April; this page is updated when new data is released.
How much asbestos waste goes to landfill in the UK each year?
At least 230,000 tonnes of asbestos-containing waste is estimated to be sent to landfill in England each year — the figure most widely quoted across the waste-management and asbestos-removal sectors. It is an estimate rather than a hard published headline, which is exactly why the underlying data source matters: the Environment Agency's Waste Data Interrogator records waste movements at around 6,000 regulated sites in England and is queryable by European Waste Catalogue (EWC) code, so asbestos-specific tonnages under codes 17 06 01* and 17 06 05* can be extracted directly for any calendar year.
The 2023 Waste Data Interrogator (the latest full-year release) was published on 25 September 2024 and last revised on 23 September 2025; the companion Hazardous Waste Interrogator covering 2024 movements followed in September 2025. Because asbestos is a hazardous waste, the Hazardous Waste Interrogator is the sharpest source of all: it tracks asbestos-coded consignments from origin to destination, which is how the movement of asbestos through transfer stations and into permitted landfill can be measured rather than guessed.
Two things drive that ~230,000-tonne stream. The first is the sheer quantity of asbestos still in place — an estimated 6 million tonnes across roughly 1.5 million UK buildings, which we cover in full on our asbestos in UK homes and buildings statistics page. As those buildings are refurbished and demolished, their asbestos steadily enters the waste stream. The second is that, unlike most construction waste, virtually none of it can be recycled — so almost every tonne removed is a tonne that has to be buried.
Where can asbestos waste be legally disposed of in England and Wales?
Only at a landfill specifically permitted for hazardous waste — never a general skip, a household waste-and-recycling centre by default, or an ordinary non-hazardous tip. Under GOV.UK disposal guidance, asbestos must go either to a dedicated hazardous-waste landfill or to a specially engineered, separately sealed cell (a "mono-cell") within a non-hazardous site, where it is kept apart from other waste and covered to stop fibres escaping.
The practical route for most asbestos runs through a licensed transfer station first. Asbestos waste must be double-wrapped in UN-approved packaging, labelled, and moved under a hazardous-waste consignment note that follows it from removal site to final landfill — the paper trail that feeds the Hazardous Waste Interrogator. The number of sites permitted to accept it is far smaller than the number that take general construction waste, which is one reason disposal costs are high and why gate availability varies sharply by region.
A small number of sites can also treat rather than bury asbestos. High-temperature thermal treatment destroys the fibres instead of entombing them, but capacity is marginal: the UK's leading operator, Thermal Recycling, holds an Environment Agency permit for just 29,500 tonnes a year of cement-bonded chrysotile — a fraction of the ~230,000 tonnes landfilled annually. Until that capacity scales up, landfill remains the destination for the overwhelming majority of UK asbestos waste.
How much does it cost to dispose of asbestos waste in the UK?
Several hundred pounds per tonne, all-in — and Landfill Tax is a large, fixed part of that bill. Because asbestos is classed as an active waste rather than an inert one, it attracts the standard rate of Landfill Tax, not the much cheaper lower rate that applies to clean rubble and soil. From 1 April 2026 the standard rate is £130.75 per tonne, up from £126.15 in 2025; the lower rate, by contrast, is only £8.65 per tonne.
| From | Standard rate (asbestos) | Lower rate (inert) |
|---|---|---|
| 1 April 2024 | £103.70 per tonne | £3.30 per tonne |
| 1 April 2025 | £126.15 per tonne | £4.05 per tonne |
| 1 April 2026 | £130.75 per tonne | £8.65 per tonne |
The tax is only the floor. On top of it sit the landfill operator's gate fee for accepting hazardous waste, transport in specialist packaging, and — for most jobs — the cost of licensed or notifiable removal in the first place. Sector cost guides in 2025 put gate and disposal fees roughly in the £50–£200-plus per-tonne range on top of the tax, so all-in disposal commonly reaches several hundred pounds per tonne before removal labour is even counted. The steep RPI-linked rise in the standard rate — from £103.70 in 2024 to £130.75 in 2026 — has pushed those costs up sharply in just two years, and is one of the pressures cited for the rise in illegal dumping of construction waste.
Is fly-tipping asbestos common, and what does it cost councils to clear?
Asbestos is a small share of fly-tipping by volume but a disproportionately costly one to clear. Defra's fly-tipping statistics for England 2024/25 record 1.26 million incidents in total, a 9% rise on the 1.15 million logged in 2023/24. Asbestos accounts for well under 1% of those incidents — but every one is a hazardous clean-up that a council cannot simply shovel into a general truck, because the waste has to be handled, packaged and taken to a permitted hazardous-waste site under the same rules as legal disposal.
The more revealing number is the construction category. Construction, demolition and excavation material accounted for roughly 70,000 fly-tips in 2024/25, a 12% year-on-year rise — faster than the overall increase, and the category that carries most illegally dumped asbestos, since asbestos-containing materials enter the waste stream through exactly this kind of building work. Clearing the largest fly-tips — those of a tipper-lorry load or bigger, the size band into which dumped building and asbestos waste typically falls — cost English local authorities £19.3 million in 2024/25.
Here we isolate only the asbestos and construction-hazardous slice of the picture; the full breakdown of overall fly-tipping volumes, enforcement actions and total clearance costs across all waste types is Defra-owned national data, not asbestos-specific. What matters for asbestos is the direction of travel: rising disposal costs, rising construction fly-tips, and a hazardous fraction that turns a small number of incidents into an outsized bill.
How does asbestos fit into the UK's wider landfill and construction waste?
Landfill is a shrinking route for most waste — but the only legal route for asbestos. According to Defra's UK statistics on waste, the UK sent 45.0 million tonnes of waste to landfill in 2020, about 24.2% of all waste treated that year. Recovery and recycling have steadily displaced landfill for most streams: England generated 63.0 million tonnes of non-hazardous construction and demolition waste in 2022, of which 94.3% was recovered.
Asbestos is the stubborn exception to that recovery story. The small hazardous slice of construction and demolition waste — largely asbestos, along with contaminated paints, oils and treated timber — cannot be crushed and reused like clean concrete or brick. That is why, even as the construction sector recovers the overwhelming majority of its waste, asbestos keeps flowing into the ground at a steady ~230,000 tonnes a year. It is, in effect, the material that the circular economy still cannot close the loop on.
| Measure | Figure | Data period / source |
|---|---|---|
| Asbestos waste to landfill, England | ~230,000 tonnes/year | Widely cited sector estimate |
| All UK waste to landfill | 45.0 million tonnes (24.2% of waste treated) | 2020 (Defra, UK statistics on waste) |
| Non-hazardous C&D waste, England | 63.0 million tonnes (94.3% recovered) | 2022 (Defra, UK statistics on waste) |
| Thermal-treatment permit capacity | 29,500 tonnes/year | Thermal Recycling / EA permit |
Why the waste stream keeps growing
Around 5,000 people a year still die in Great Britain from past asbestos exposure — including 2,218 mesothelioma deaths recorded in 2023 — the legacy that both drives the removal work and keeps feeding the waste stream (HSE, mesothelioma statistics, July 2025). Every survey, refurbishment and demolition of a pre-2000 building has the potential to add to the tonnage moving through transfer stations and into landfill.
That creates a slow, decades-long pipeline. The 6 million tonnes of asbestos estimated to remain in UK buildings is not removed all at once; it comes out building by building as properties reach the end of their life or are refurbished, which is why the ~230,000-tonne annual flow is expected to continue for many years rather than tail off quickly. The rising cost of doing it legally — driven largely by the RPI-linked Landfill Tax — is the single biggest pressure point, both on legitimate contractors' margins and on the temptation to dump. For the workers whose jobs put them closest to this material, recognising it before it becomes waste is the first line of defence, which is where asbestos awareness training comes in.
Frequently asked questions
How much asbestos waste goes to landfill in the UK each year?
At least 230,000 tonnes of asbestos-containing waste is estimated to be sent to landfill in England every year. It is a sector-cited estimate rather than a single published headline; the underlying tonnages can be computed from the Environment Agency's Waste Data Interrogator and Hazardous Waste Interrogator using the asbestos EWC codes (17 06 01* and 17 06 05*).
Where can asbestos waste be legally disposed of in England and Wales?
Only at a landfill permitted for hazardous waste — either a dedicated hazardous-waste site or a separately sealed mono-cell within a non-hazardous site. It must be double-wrapped, labelled and moved under a hazardous-waste consignment note, usually via a licensed transfer station. It can never go in a general skip or an ordinary household tip.
How much does it cost to dispose of asbestos waste in the UK?
Several hundred pounds per tonne all-in. Asbestos attracts the standard rate of Landfill Tax — £130.75 per tonne from 1 April 2026, up from £126.15 in 2025 — and on top of that sit landfill gate fees (roughly £50–£200-plus per tonne per 2025 sector guides), specialist transport, and the cost of licensed or notifiable removal.
Is fly-tipping asbestos common, and what does it cost councils to clear?
Asbestos makes up well under 1% of England's 1.26 million fly-tipping incidents in 2024/25, but each one is a hazardous, costly clean-up. The construction, demolition and excavation category that carries most dumped asbestos rose 12% to around 70,000 incidents, and clearing the largest fly-tips cost councils £19.3 million in 2024/25.
Can asbestos waste be recycled or destroyed instead of buried?
In principle yes — high-temperature thermal treatment destroys asbestos fibres and produces an inert material — but capacity is tiny. The UK's leading operator holds an Environment Agency permit for just 29,500 tonnes a year, against the ~230,000 tonnes landfilled annually, so burial remains the destination for the vast majority of UK asbestos waste.
What are the EWC codes for asbestos waste?
The main European Waste Catalogue (List of Waste) codes are 17 06 01* (insulation materials containing asbestos) and 17 06 05* (construction materials containing asbestos). The asterisk marks them as hazardous. These are the codes used to filter the Environment Agency's Waste Data Interrogator for asbestos-specific tonnages.
For tradespeople and anyone whose work disturbs the fabric of pre-2000 buildings, asbestos awareness training is a legal requirement under Regulation 10 of the Control of Asbestos Regulations 2012. Our CPD-certified Asbestos Awareness Course covers where asbestos hides, how to avoid disturbing it, and how it must be handled once removed.
With disposal costs rising every April, make sure your team can recognise asbestos before it becomes hazardous waste.
