Westminster Hall is an alternative Chamber for MPs to hold debates, named after the adjoining Westminster Hall.

Absolutely. This is an issue for the whole of the United Kingdom.

The disaster brought about the Mines and Quarries (Tips) Act 1969, which came into force to improve coal tips’ stability and safety. However, it did not go far enough. Aberfan should have been a moment to address the dangerous legacy of all coal tips once and for all, but the job remains unfinished. Now, because of increasingly violent storms caused by climate change, we have experienced further coal tip slips. There was a major landslide above Tylorstown in Rhondda Fach in 2020, and then in November 2024, in Cwmtillery, a slip was caused by heavy rainfall from Storm Bert. That led to a slurry and debris slide that forced the evacuation of homes.

Plaid Cymru has long warned that the safety of our coal tips is not a matter for tomorrow; it must be addressed urgently. No family should go to bed fearing a landslide on the hillside above them. No community should be left to foot the bill for the negligence of past Governments. The Senedd recently passed the Disused Mine and Quarry Tips (Wales) Act 2025, which will establish the Disused Tips Authority for Wales, the powers of which will include requiring landowners to ensure that coal tips located on their land are stable. We must, however, not forget that the issue of coal tips predates the dawn of devolution. It is an historic injustice that the cost of making these tips safe has not been fully funded by Westminster, and that the people of Wales are now expected to foot a large part of this bill.

I welcome this debate, but I would like the hon. Member to acknowledge the fact that the UK Government have given £140 million towards making these coal tips safe, which is absolutely vital. I know that bigger figures have been bandied about, but would she agree that there is a limit to how much we can do in any one or two years, and that that was the amount asked for by the Welsh Government? It does not preclude opportunities in the future to ask for more, when more plans are ready.

Absolutely, but we need £600 million to make these tips safe. The Government responded to my written question in June that the Labour Welsh Government had not asked for the full amount of the estimated £600 million needed to make all tips in Wales safe. Plaid Cymru believes it is a grave injustice to the people of the valleys that the full cost is not covered by Westminster. I reiterate our call on the Government to fully fund remediation work to make coal tips safe in Wales.

Without full funding from Westminster, it leaves the door open to a new generation of mining companies waiting to mine these coal tips under the guise of remediation. That is because the new Welsh Disused Tips Authority will require landowners to make the coal tips safe, and they will likely seek to avoid that extra cost. There is a real risk that mining companies will offer to carry out remediation work on behalf of landowners for free, in return for the commercial rights of any coal that they extract. These companies have proven to us that they cannot be trusted with the stewardship of our environment.

The local authority area of Carmarthenshire has 170 coal tips. My constituency borders some of the largest tips in Wales, one of which is the waste from the East Pit open-cast coalmine, a prime example of where a company has betrayed the trust of the community. In that instance, the company, Celtic Energy, continued to mine coal from the site beyond the expiry of its planning permission. It then failed to restore the coalmine and remediate the local coal tip, abandoning the site and the community with the task incomplete. We cannot allow this to become a pattern by letting the coalmining industry of Wales’s past return to carve open our countryside once again. Making coal tips safe for our communities should be the priority, whether that is through flattening, removing or reprofiling them.

The UK Government have pledged to ban new coalmining licences, but they have confirmed their belief that re-mining coal from the tips does not require a licence, meaning that such activity falls outside the scope of the proposed ban. Although the Welsh Government believe that their own planning policies will prevent re-mining, a loophole allowing coal extraction in “wholly exceptional circumstances” has raised concern among campaigners such as the Coal Action Network. I thank Anthony, who is here today, for his help in preparing for this debate. I also congratulate him on his wedding anniversary—when he should be home, he has come to support us here.

The loophole can be resolved by amending the Coal Industry Act 1994 to require licensing for the re-mining of coal tips, and ensuring that that is included in a UK-wide ban. We must prevent a new industry of commercial coal tip mining from taking root and perpetuating fossil fuel pollution. I urge the Government to extend their coal licence ban to cover the re-mining of coal tips.

Tomorrow is the Senedd by-election in Caerphilly—a local authority area with 207 coal tips, 56 of which are deemed a clear threat to public safety. As we know, voters will get to choose between two different visions for the future of Caerphilly. The vision of Reform and the hon. Member for Clacton (Nigel Farage) is one of reopening the coalmines in Wales. He wants to send our people back down underground to slave away in the dark for hours, developing pneumoconiosis from inhaling toxic dust—all to exploit the people of Wales yet again.
