Developments of national significance meaning

What does Developments of national significance mean?
Developments of national significance (DNS) are applications for specified infrastructure projects in Wales that are determined by the Welsh Ministers, rather than the local planning authority. The term and thresholds are set by the Planning (Wales) Act 2015 and secondary legislation specifying the categories of development within the regime. Key features include a centralised decision-making process, pre-application consultation, examination by Planning and Environment Decisions Wales (PEDW), a Local Impact Report from the affected authority, and a ministerial decision. The Welsh Ministers may determine prescribed secondary consents. There is no right of appeal; decisions are challengeable by judicial review. The DNS regime is similar to the nationally significant infrastructure projects (NSIP) process under the planning act 2008 in England, but differs in key respects: DNS results in planning permission (not a single development consent order) and does not confer compulsory acquisition powers, which must be pursued separately. DNS is used for nationally important projects (for example, certain onshore energy and related infrastructure) that meet prescribed thresholds. The concept is specific to Wales; comparable centralised consenting exists elsewhere but under different terms and statutes (England: NSIPs; Scotland: national or major developments/section 36 consents; Northern Ireland: regionally significant development; Ireland: strategic infrastructure development).

In a robust dissent, Lord Leggatt criticised the majority’s stance in Mr Shvidler’s appeal, holding that the measures against him, as a UK national, were disproportionate and thus unlawful. With...

Planning law update: brownfield passports, Grenfell Tower Inquiry phase 2, Welsh building safety reforms and Infrastructure (Wales) Act consenting consultation, plus updated planning practice notes — 26 September 2024

In this issue: Housing Building regulations Developments of national significance/infrastructure consents in Wales Daily and weekly news alerts New and updated content Related Documents Housing MHCLG publishes policy paper on brownfield passports. The Ministry of Housing, Communities and Local Government (MHCLG) has released a policy paper on ‘brownfield passports’. It outlines plans to maximise clarity and certainty around making best use of urban land, with further changes to policy at national and/or local level covering the principle, scale and form of development in different locations. Framed as a ‘brownfield passport’, policy would set clear parameters for brownfield schemes which, if satisfied, act as accepted indicators of suitability, making approval the default and accelerating decisions. The passport is intended to reduce the risk, cost and uncertainty of obtaining planning permission. These proposals sit within the government’s ‘brownfield first’ approach to development.

The principal statute regulating control of foreign direct investment (FDI) is Law No. 174/2021 on the mechanism for examining investments of significance for state security.

Infrastructure (Wales) Act 2024: Infrastructure Consent Orders for Significant Infrastructure Projects - thresholds, process, associated development, deemed consents, compulsory acquisition, modification, enforcement and judicial review

The Infrastructure (Wales) Act 2024 (I(W)A 2024) introduces a single, coherent consenting route for particular infrastructure schemes in Wales and in Welsh waters. For any ‘significant infrastructure project’ (SIP) that exceeds specified thresholds in defined sectors, developers must secure infrastructure consent through an infrastructure consent order (ICO). An ICO is designed to wrap together the complete set of authorisations needed so that the development can proceed... Energy Transport Waste Water Gas Before I(W)A 2024: Developments of National Significance The Planning (Wales) Act 2015 amended the Town and Country Planning Act 1990 (TCPA 1990) to introduce ‘developments of national significance’ (DNSs). This created an expedited route to planning permission, with applications sent straight to the Welsh Ministers, rather than considered by local planning authorities. The DNS process is administered by the Planning Inspectorate Wales (PINS Wales) on the Welsh Ministers’ behalf. See Practice Note: Permission for Developments of National Significance in Wales. However, the DNS framework does not include the...
