HS2’s £100m Bat Protection Structure: An Examination of Project Costs and Regulations

Sir John Thompson, chairman of the HS2 rail line, stated that £100 million was being allocated for a protective structure for bats within ancient woodland in Buckinghamshire. He presented this as one instance among 8,276 “consents” mandated by public bodies, conveying his exasperation with the regulatory framework in the UK. The question arises as to how this cost reached £100 million and why significant infrastructure developments encounter such complexity. Oliver Harmar, chief operating officer at Natural England, commented, “We are facing a nature crisis with one in six species in the UK now facing extinction. That is why development must be sustainable.” This government organization is responsible for upholding legislation designed to safeguard wildlife and the environment. Its function is not to determine the approval of large infrastructure projects, but rather to provide consultation on proposals and guarantee that environmental harm is prevented where feasible, or mitigated if unavoidable. Numerous species, including badgers, bats, and great crested newts, benefit from legal protection. Consequently, Natural England is required to grant a license prior to the commencement of any activities that might adversely affect these species. Tony Juniper, chairman of Natural England, previously noted that the body had received “a high number of inquiries” concerning HS2 from individuals interested in conservation. He stated, “Many concerns quite understandably relate to our rarest wildlife and habitats, such as ancient woodland and bats.” Among the bat species that will benefit from the 1-kilometer-long protective structure are Bechstein’s bats, recognized as one of the globe’s rarest bat species. Mr. Harmar stated, “There is ample evidence – despite claims made to the contrary – that they [the bats] are at risk of colliding with high-speed trains.” Gareth Dennis, a railway design engineer and author who was involved with the HS2 section passing through Calvert in Buckinghamshire, concurred. He remarked, “Eighteen trains an hour in each direction is a lot of pressure,” and further added, “We must protect our biosphere – it is not a zero-sum game,” referencing a recent Office for National Statistics report that assessed UK ecosystems at £1.8 trillion. Natural England did not propose the concept of the bat tunnel but confirmed its efficacy when consulted. A spokesperson for HS2 Ltd indicated that “multiple options” had been evaluated, such as green bridges and habitat restoration, in order to “comply with laws protecting vulnerable species.” The spokesperson added that following “extensive engagement” with Natural England, “a covered structure was designed.” The spokesperson further noted that “Its size has doubled over time, partly due to the need to accommodate future provision for local rail services.” Mr. Dennis clarified that the structure “originally cost £40m, then some wranglings with East West Rail made it a four-track structure and pushed up the cost.” East West Rail is a distinct initiative focused on connecting Oxford and Cambridge via rail. Natural England is not the sole entity providing approval for elements of the HS2 railway. Major infrastructure endeavors obtain a Development Consent Order (DCO) from the government; however, local authorities retain oversight concerning the design of structures like viaducts and tunnels. Planning permission may also be necessary for elements such as lorry routes, storage of construction materials, communication masts, fences, and lighting. HS2 Ltd reported that it had appealed to the Planning Inspectorate to override local authorities on a minimum of 23 occasions, which included Buckinghamshire Council’s opposition to the bat shield proposal. Additionally, approvals are needed from the Environment Agency “for water management, excavation below the water table and similar things.” Gavin Pearson, editor of New Civil Engineer, commented, “In recent years, achieving a DCO has been taking longer than many think it should. “Good plans have sat waiting for years, which means things like cost projections will be out of date.”If you multiply that same problem for planning processes at local authorities, the implications can be huge.” He observed that engineering projects are capable of managing “complex planning rules,” but noted a “growing inability of planning processes to keep pace with applications.” Sir Geoffrey Clifton-Brown, who chairs the Public Accounts Committee and serves as Conservative MP for North Cotswolds, characterized it as “ridiculous” that HS2 was required to seek 8,276 distinct consents. He asserted, “It should be a procedure whereby when the project is granted permission, these consents are automatic.” The Local Government Authority, representing local councils, chose not to provide a comment. Peter Martin, Buckinghamshire Council’s Deputy Cabinet Member for HS2, stated, “Whilst the council wishes to protect species such as Bechstein’s bats, one of the country’s rarest species, it was never supportive of what seemed like extremely excessive costs for a single structure.” He affirmed that the council maintained its “fundamental opposition to High Speed 2.” He further added, “We will continue to work tirelessly to mitigate the impact of the construction of the project on our local communities, environment, and infrastructure, particularly our roads, which are being severely damaged by HS2 construction traffic.” Transport secretary Louise Haigh described the £100 million bat shield as a “shocking example” of the “complete lack of efficiency” associated with the rail initiative, which has a potential total cost of £66 billion. She remarked, “Since becoming transport secretary, I have seen up close the scale of failure in HS2’s project delivery and this is just the tip of the iceberg.” Beyond expenses and delays related to legal and planning processes, the escalating cost has been attributed to inflation, particularly an increase in the price of materials like concrete and steel, as well as inadequate forecasting. Ms. Haigh indicated that while she acknowledged the “importance of meeting legal obligations,” a “sensible balance” regarding costs was essential. She stated, “I will be looking at what other systemic reforms we can put in place to ensure public money is put to good use and not wasted.” She concluded, “Through this tighter control, we will remove barriers that lead to project delays and eye-watering additional costs to taxpayers.” HS2 Ltd explained that a factor contributing to the project’s higher cost in the UK compared to countries like France or Spain, both recognized for high-speed rail, is the terrain. A spokesperson noted, “More than half of the HS2 route is either in tunnels (32 miles) or cuttings (44 miles) which are a lot more expensive than building on the surface. European railways are generally on the surface.” They further added, “We also tend to have more environmental mitigations, like the bat structures or green bridges.” Nevertheless, Mr. Pearson remarked that while “the UK has had some very high-profile cases of high-cost projects recently, this isn’t unique to the UK.” He elaborated, “Such challenges are quite common around the world, and although specific regulations will reflect different priorities in different countries, complexity is pretty normal now.” As an illustration, reports indicate that EU legislation safeguarding the rare Siberian flying squirrel has similarly impeded significant infrastructure projects in locations such as Finland.
