Development consent order meaning

What does Development consent order mean?
In practice, a development consent order (dco) is the single, statutory consent used to authorise a nationally significant infrastructure project (NSIP), bundling planning permission and related powers into one order. It is a planning act 2008 process and term, with development consent granted by the relevant Secretary of State by statutory instrument, following an examination by the Planning Inspectorate (as Examining Authority). DCOs typically authorise the construction and operation of major energy, transport, water and waste schemes. A DCO may incorporate or disapply certain separate consents (for example, listed building consent), impose requirements (planning-style conditions), and confer powers for compulsory acquisition, temporary possession, highway and street works, protective provisions and the extinguishment or creation of rights. The regime applies principally in England and, for reserved matters, in parts of Wales and adjacent waters. Scotland and Northern Ireland use different consenting routes (for example, Electricity Act section 36 and regionally significant development), and do not use DCOs. In Ireland, broadly comparable projects proceed as strategic infrastructure development determined by An Bord Pleanála. Practically, a DCO offers a unified, timetable-driven consent for NSIPs, concentrating environmental assessment, land powers and operational controls in a single legal instrument.

The court also confirmed that any uncertainty within prior approvals can be resolved by referring to the application paperwork and drawings, ensuring compliant aspects remain authorised while only non-compliant works face enforcement.

PRACTICE NOTES
Promoting compulsory purchase orders under the Acquisition of Land Act 1981: negotiations, land referencing, drafting and making orders, statement of reasons, and notice/publicity requirements (England and Wales)

Context Numerous statutory regimes confer compulsory purchase powers for defined aims on designated bodies (see Practice Note: Sources and limits of compulsory purchase powers). Ordinarily, authority to compel acquisition is given through a compulsory purchase order (CPO). The specified body, known as the acquiring authority, makes the order, which is then confirmed by the confirming authority—either the minister empowered to authorise compulsory acquisition, an inspector appointed to act on the minister’s behalf, or in certain circumstances the acquiring authority itself. This Practice Note concentrates on the steps for promoting a CPO governed by the Acquisition of Land Act 1981 (ALA 1981). ALA 1981 covers the majority of compulsory acquisitions undertaken by public bodies. Distinct procedures can, however, apply where compulsory acquisition is embedded within development consent orders under the Planning Act 2008 (PA 2008). That route is outside the scope of this Practice Note; for guidance see: Practice Notes—Compulsory acquisition for NSIPs—introduction and principles; Compulsory acquisition for NSIPs—application, draft DCO and supporting documentation; and Compulsory acquisition for NSIPs—examination, making...

NSIP DCO examination procedure: fast-track, written representations, hearings, changes, local impact reports, statements of common ground, and decision-making under the Planning Act 2008 (including forthcoming 2025 amendments)

The Planning Act 2008 (PA 2008) establishes the consent framework for nationally significant infrastructure projects (NSIPs) across energy, transport, water, waste water and waste. Decisions on development consent order (DCO) applications may be taken by reference to any relevant National Policy Statements (NPSs), which articulate national policy for NSIPs. See Practice Note: National Policy Statements. While the Secretary of State (SoS) is legally accountable for the decision, in practice the government entrusts acceptance and examination of applications to the Planning Inspectorate (PINS). See Practice Note: Examination of nationally significant infrastructure projects—general. The government has issued a ‘Collection: National Infrastructure Planning Guidance Portal’, containing guidance on NSIP pre-examination, the examination itself, the fast-track route for NSIPs, and awards of costs relating to the examination of DCO applications. Collectively, these provisions define the route by which nationally significant schemes are assessed and authorised, with guidance set out in practice notes and the collection. Fast-track process Under PA 2008, s 98(1), the Examining Authority (EA) must conclude examination of the application...

Land Registry: are superior title (Form N) consents required to register a s.56 1993 Act lease extension?

Where a long residential lease is extended under section 56 of the Leasehold Reform, Housing and Urban Development Act 1993 (LRHUDA 1993) and the freehold is subject to a Form N restriction in respect of a charge to the freeholder’s lenders, will the HM Land Registry require lender consent to be submitted in order for the lease extension to be registered notwithstanding that the lease extension is pursuant to statute? A restriction entered on the register indicates that the proprietor’s power to deal with the land is constrained in some manner. Its practical effect is either to bar registration of a disposition, or to oblige the applicant to satisfy specified requirements before registration can proceed, for example by producing evidence of consent from the person entitled to the benefit of the restriction. A restriction may apply to every disposition, or be confined to a defined class of disposition. It can prevent any entry from being made permanently, for a stated period, or until a stated...

Para 20 ECC orders: Rights without prior operator occupation

The Electronic Communications Code The Electronic Communications Code (the ‘Code’), found in sections 106–119 and Schedule 3A Pt 1 to the Communications Act 2003, enables Ofcom-authorised operators to obtain rights over land for a range of purposes (see Code para 3). Code rights can be conferred by agreement between a land occupier and an operator, and, in practice, telecoms providers ordinarily seek to secure consensual terms at the outset. If agreement cannot be reached, the Upper Tribunal (UT) has authority to confer Code rights without the occupier’s consent. The process is initiated by the operator serving a notice under paragraph 20 of the Code...
