Future supply of construction materials ‘approaching a cliff edge’

Latest MPA Annual Mineral Planning Survey reveals declining levels of permitted reserves

THE Government needs to take urgent action to address diminishing reserves of the UK-sourced minerals that are essential for housing and infrastructure, according to a new survey published by the Mineral Products Association (MPA).

In its latest Annual Mineral Planning Survey (AMPS) report, the MPA says Britain has an abundance of essential mineral resources and is almost entirely self-sufficient in meeting the 250-million-tonne-a-year demand for materials, 30% of which comes from recycled or secondary sources.

However, for more than a decade the rate of consumption – mainly for construction – has not been matched by the rate of approval for new planning consents for quarrying, due to a ‘broken’ mineral planning system that often allows local interests to be prioritized above national need.

Between 2014 and 2023, for every 100 tonnes of sand and gravel used in Great Britain, an average of 61 tonnes of new permissions have been granted. And for crushed rock the figure is even lower, with only 33 tonnes of new material consented for every 100 tonnes consumed.

The MPA warns that this situation is not sustainable in the medium term, especially given the Government’s ambitions in house building and energy infrastructure. The country could face negative consequences both economically and environmentally if the current issues are not addressed as part of the Government’s planning reforms.

Like the country’s geology, the picture varies between regions, with areas that have traditionally been nationally important ‘strategic’ suppliers, such as the East Midlands and South West, seeing significant shortfalls over the last 10 years. The south-east of England consumed three times the volume of new permitted reserves for sand and gravel, while the East Midlands saw materials sales 18 times the volume of new permitted reserves.

And whilst the average time taken for planning permission to be obtained has remained broadly the same, the MPA is keen to highlight that the entire planning process can often take 10 to 15 years to complete.

Looking ahead, the MPA economic analysis indicates that between 3.8 and 4.1 billion tonnes of aggregates will be required over the next decade to support the country’s construction needs. Maintaining the sustainable and cost-effective supply of these strategically important materials will require active management, planning, and investment, supported by regular surveys and up-to-date data to monitor performance.

Aurelie Delannoy, director of economic affairs at the MPA, said: ‘Our new AMPS report is timely, published as the new Government looks to reform the planning system with housing and infrastructure at the top of its agenda. The MPA’s members are working hard to produce and deliver the essential mineral products needed to deliver the Government’s ambitions, but unless there are significant reforms to streamline mineral planning and permitting, along with a change in the investment environment, these mineral reserves will not be fully replaced. That will not only impact the mineral products industry but also the UK construction industry and the wider economy.’

Mark Russell, executive director at the MPA, said: ‘Our survey shows the availability of essential minerals is fast approaching a cliff edge. If the long-term trend of diminishing reserves from local domestic sources continues, it is inevitable that the tensions involved in maintaining future supply will be exacerbated. In turn, this will result in increased costs to supply, but also increased energy consumption and emissions, as materials will have to be transported over ever-growing distances to fulfil demand.

‘An increasing number of planning applications appear to be being refused against local authority planning officer recommendations. Consequently, the mineral products industry is increasingly having to plan by appeal, as was the situation in the 1990s. Nothing gets built without minerals and that’s why we’re asking the Government to include mineral planning as an integral part of the proposed planning reforms.’
