There are just over 2,500 coal spoil tips in Wales, with a large number classed as "high risk", following recent landslides in the South Wales Valleys. A taskforce was set up by the Welsh and UK governments to investigate the issue, with the Coal Authority conducting inspections.
Funding for ensuring the safety of the coal tips had become a source of dispute between the UK and Welsh Governments as coal tip safety is devolved to Wales. The UK Government states no additional funding would be provided on a devolved matter. However, Welsh politicians argue coal tips pre-date devolution and therefore the UK Government should contribute. It is estimated to cost between £500 million and £600 million over 10–15 years to fully address the issue.
Wales has numerous coal tips, as a legacy of its coal industry. It is estimated it is home to 40% of all UK coal tips. [1] [2] Almost all coal tips are disused, however they continue to present safety risks, such as the possibility of pollution, landslides, flooding and spontaneous combustion. Climate change has been connected to the increasing intensity of rainfall in the winter and flash flooding, increasing the risk of coal tips becoming more unstable. [3] [2] The 1966 Aberfan disaster, where a coal tip in Aberfan collapsed killing 116 children and 28 adults, was the worst mining-related disaster in Wales' and Britain's history, [4] [5] and serves as a reminder of the potential risk of unstable coal tips. [1] [2] [6]
On 16 February 2020, following Storm Dennis, a slip occurred at the Llanwonno coal tip [7] in Tylorstown, Rhondda Fach. 20 tips were then checked to ensure no more slips could occur. [8] Following which a joint task force, the "Coal Tip Safety Taskforce" [9] was set up by the Welsh and UK governments to assess the risk of coal tips in Wales and to review existing policy on the management of disused coal tips. The Coal Authority was commissioned to inspect coal tips in Wales, and report any urgent work needed. There is no standard approach to assessing the risk of coal tips in the Mines and Quarries (Tips) Act 1969, with the Coal Authority relying on Rhondda Cynon Taf County Borough Council's method of assessment to categorise the risk of the tips. [10] Following the slip, it was revealed no national list of coal tips exists. [11]
The first round of inspections of coal tips by the Authority was completed in July 2020. [10]
In October 2020, the UK Government provided £2.5 million to clean up the Tylorstown site, which involved the cleaning up of 60,000 tonnes (130,000,000 lb) of collapsed soil, which started in June 2020. [12] [13] In November, it was reported that securing 2,000 old coal tips in Wales, would potentially cost between £500 million and £600 million over the next 10–15 years. [12] [14] With repairs in Rhondda Cynon Taf only, estimated to be £82.5 million. [13] In December 2020, another landslip of the coal tip in Wattstown, Rhondda Cynon Taf occurred, although there were no properties near the tip. [15]
In 2021, the Welsh Government announced it would review the legislation on coal tip inspection and maintenance, with the Law Commission. [9] [10] By October 2021, slips had occurred near Clydach Vale, Mountain Ash, Clydach and Pontygwaith. [7] In May 2022, the Welsh Government published a White paper on coal safety. [9] The government also recommended the establishment of a "new supervisory body" to oversee coal tip safety in Wales. [16]
In 2023, the Welsh Government released an interactive map of the 350 disused coal tips that are required to have more frequent inspections. [6] The government also contacted 1,500 landowners and almost 600 property occupiers in Wales, informing them that there is a coal tip (entirely or partly) on their land. The government allocated an additional £44.4 million to local authorities to continue the maintenance and inspection of public and privately owned coal tips. [17]
A "Disused Tips Bill" was expected to be introduced to the Senedd by 2024. [17]
In the October 2024 United Kingdom budget, the UK Government pledged £25 million to coal tip safety in Wales. [18]
By July 2020, 2,144 coal tips were identified in Wales, mostly in the South Wales Valleys, [1] with 294 deemed high-risk at the time. Of them, 73% were privately owned, and 27% publicly owned by councils, Natural Resources Wales (NRW) or the Coal Authority. [3] [10] In October 2021, the total number was increased to 2,456 following the Welsh Government publishing the list of the sites and the principal area of Wales they are located in. However they refused to publish their exact locations, until they are shared with councils and further work is done. [7] [19] 327 of these tips were classed as high-risk. [20]
By 2020, the Coal Authority had 24 coal tips in Wales under its management while NRW had 112, of which one in Treherbert was classed as "high risk" at the time, and was co-monitored with the Authority. [11]
In 2021, the 2,456 sites were categorised A–D, with those in C and D classed as "higher risk", therefore a potential to cause a risk to safety, although not an imminent or immediate threat. [7] [9]
The full categorisation is as follows: [9]
The Coal Authority has been given the responsibility to perform inspections. [9]
The data below is as of 14 November 2023, recording a total 2,566 tips. There are no recorded disused coal tips in Ceredigion, Conwy, Denbighshire, Gwynedd, Newport or the Vale of Glamorgan. [9]

In January 2020, the Coal Authority released a list of all the 39 coal tips they manage in Great Britain, with 24 being in Wales, 10 in England and 5 in Scotland. Those in Wales are listed below: [21]
Coal tip safety is devolved to Wales, therefore the responsibility of the Welsh Government. [9] [12] The legislation setting the framework for coal tip safety is the "Mines and Quarries (Tips) Act 1969", which was passed when Wales had a coal mining industry. [9] The Welsh Government has called on the UK Government to provide funding to review the coal tips, as the government argued they were created before devolution. The UK Government stated it does not plan to provide the £500–600 million over 10–15 years that the Welsh Government was requesting to secure 1,200 Welsh coal tips. The UK Government stated, as it is a devolved matter, it shouldn't be expected that the UK Government would provide additional funding for it. As a result of the lack of UK funding, Welsh finance minister, stated the Welsh Government would have to divert funding from education, transport, housing and other devolved matters. [7] [22] [14] [1] The Coal Authority, a UK government department, oversees the inspection and safety of the sites. [23]
Thomas George Thomas, 1st Viscount Tonypandy, was a British politician who served as a member of parliament (MP) and Speaker of the House of Commons from 1976 to 1983. He was elected as a Labour MP.
Rhondda Cynon Taf is a county borough in the south-east of Wales. It consists of five valleys: the Rhondda Fawr, Rhondda Fach, Cynon, Taff and Ely valleys, plus several towns and villages away from the valleys.
The Aberfan disaster was the catastrophic collapse of a colliery spoil tip on 21 October 1966. The tip had been created on a mountain slope above the Welsh village of Aberfan, near Merthyr Tydfil, and overlaid a natural spring. Heavy rain led to a build-up of water within the tip which caused it to suddenly slide downhill as a slurry, killing 116 children and 28 adults as it engulfed Pantglas Junior School and a row of houses. The tip was the responsibility of the National Coal Board (NCB), and the subsequent inquiry placed the blame for the disaster on the organisation and nine named employees.
South Wales is a loosely defined region of Wales bordered by England to the east and mid Wales to the north. Generally considered to include the historic counties of Glamorgan and Monmouthshire, south Wales extends westwards to include Carmarthenshire and Pembrokeshire. In the western extent, from Swansea westwards, local people would probably recognise that they lived in both south Wales and west Wales. The Brecon Beacons National Park covers about a third of south Wales, containing Pen y Fan, the highest British mountain south of Cadair Idris in Snowdonia.
Ynyshir is a village and community located in the Rhondda Valley, within Rhondda Cynon Taf, South Wales. The name of the village means "long island" in Welsh and takes its name from a farm in the area, falling within the historic parishes of Ystradyfodwg and Llanwynno (Llanwonno). The community of Ynyshir lies between the small adjoining village of Wattstown and the larger town of neighbouring Porth.
The South Wales Valleys are a group of industrialised peri-urban valleys in South Wales. Most of the valleys run north–south, roughly parallel to each other. Commonly referred to as "The Valleys", they stretch from Carmarthenshire in the west to Monmouthshire in the east; to the edge of the pastoral country of the Vale of Glamorgan and the coastal plain near the cities of Swansea, Cardiff, and Newport.
Rhondda, or the Rhondda Valley, is a former coalmining area in South Wales, historically in the county of Glamorgan. It takes its name from the River Rhondda, and embraces two valleys – the larger Rhondda Fawr valley and the smaller Rhondda Fach valley – so that the singular "Rhondda Valley" and the plural are both commonly used. The area forms part of the South Wales Valleys. From 1897 until 1996 there was a local government district of Rhondda. The former district at its abolition comprised 16 communities. Since 1996 these 16 communities of the Rhondda have been part of Rhondda Cynon Taf County Borough. The area of the former district is still used as the Rhondda Senedd constituency and Westminster constituency, having an estimated population in 2020 of 69,506. It is most noted for its historical coalmining industry, which peaked between 1840 and 1925. The valleys produced a strong Nonconformist movement manifest in the Baptist chapels that moulded Rhondda values in the 19th and early 20th centuries. It is also known for its male voice choirs and in sport and politics.
Alfred Robens, Baron Robens of Woldingham, PC was an English trade unionist, Labour politician and industrialist. His political ambitions, including an aspiration to become Prime Minister, were frustrated by bad timing, but his energies were diverted into industry: he spent 10 years as Chairman of the National Coal Board, and later – despite the Aberfan disaster – headed a major inquiry which resulted in the Robens Report on occupational health and safety. His outlook was paternalistic; in later life, he moved away from his early socialism towards the Conservative Party. His reputation remains tarnished by his failure to have foreseen and prevented the Aberfan disaster, followed by actions widely regarded as grossly insensitive during the aftermath of the disaster.
Ferndale is a town and community located in the Rhondda Valley in the county borough of Rhondda Cynon Taf, Wales. Neighbouring villages are Blaenllechau, Maerdy and Tylorstown. Ferndale was industrialised in the mid-19th century. The first coal mine shaft was sunk in 1857 and Ferndale was the first community to be intensively industrialised in the Rhondda Valley.
The South Wales Coalfield extends across Pembrokeshire, Carmarthenshire, Swansea, Neath Port Talbot, Bridgend, Rhondda Cynon Taf, Merthyr Tydfil, Caerphilly, Blaenau Gwent and Torfaen. It is rich in coal deposits, especially in the South Wales Valleys.
Tylorstown is a village and community located in the Rhondda valley, in the county borough of Rhondda Cynon Taf, Wales. It is neighboured by the villages of Blaenllechau, Ferndale, Penrhys, Pontygwaith and Stanleytown.
Gwilym Elfed Davies, Baron Davies of Penrhys was a Welsh Labour Party politician.
Blaenllechau is a small village located in the Rhondda Fach valley, Rhondda Cynon Taf, Wales. Neighbouring villages are Ferndale, Maerdy and Tylorstown. The population of Blaenllechau is less than 1000. The village is defined by the river border, flowing between Blaenllechau and neighbouring Ferndale, of which the well-known Blaenllechau waterfall is a tributary.
Aberfan is a former coal mining village in the Taff Valley 4 mi (6 km) south of the town of Merthyr Tydfil, Wales.
Maerdy Colliery was a coal mine located in the South Wales village of Maerdy, in the Rhondda Valley, located in the county borough of Rhondda Cynon Taf, and within the historic county boundaries of Glamorgan, Wales. Opened in 1875, it closed in December 1990.
Ferndale Colliery was a series of nine coal mines, located close to the village of Ferndale, Rhondda Cynon Taf in the Rhondda Valley, South Wales.
The Tribunal of Inquiry into the Aberfan Disaster, chaired by Lord Justice Edmund Davies, was established in 1966 to inquire into the causes of and circumstances of the Aberfan disaster. The report of the tribunal placed the blame for the disaster on the National Coal Board (NCB), naming nine of its staff as having some degree of responsibility.

Welsh devolution is the transfer of legislative powers for self-governance to Wales by the Parliament of the United Kingdom. The current system of devolution began following the enactment of the Government of Wales Act 1998, with the responsibility of various devolved powers granted to the Welsh Government rather than being the responsibility of the Government of the United Kingdom.
