Gatwick Northern Runway order corrected and republished

If you glanced at this order and thought it was just legal housekeeping, that is partly right. On 20 January 2026 the Department for Transport made the Gatwick Airport (Northern Runway Project) Development Consent (Correction) Order 2026, and it came into force on 21 January 2026. Its job was not to grant the main runway consent again, but to correct errors and omissions in the 2025 development consent order that had already granted consent. (legislation.gov.uk) Because this is a correction order, you should read it as a legal tidy-up to an existing consent, not as the original runway approval itself. The source note also makes clear that this version was later reissued after a publication-classification mistake in the earlier instrument.

A statutory instrument, or SI, is a form of secondary legislation: law made under powers that Parliament has already set out in an Act. UK Parliament says ministers use this route to make the detailed legal changes that let legislation work in practice, and legislation.gov.uk explains that SIs can be classed as local or general, with some local SIs treated as non-print and others as printed instruments. (parliament.uk) **Quick explainer:** when you read a statutory instrument, you are not reading commentary about the law. You are reading the law’s working text. That is why even a small correction can matter more than it first appears. (parliament.uk)

Development consent orders, or DCOs, sit inside the Planning Act 2008 system for nationally significant infrastructure projects. The Act says development consent is required where a project is or forms part of a nationally significant infrastructure project, and government guidance says that if consent is given, the Secretary of State makes a development consent order. That is the legal route used for major transport schemes and airport changes. (legislation.gov.uk) So the January 2026 instrument is best understood as an edit to the Gatwick project’s rulebook, not the rulebook itself. You can think of the 2025 order as the main permission and the 2026 order as the formal correction sheet attached to it. (legislation.gov.uk)

The power to make these fixes comes from section 119 of the Planning Act 2008 and Schedule 4, which deal with correcting errors in development consent decisions. Schedule 4 says a correctable error is an error or omission in the part of the decision document that records the decision, rather than in the statement of reasons. It also says the correction route can be used only if a written request is made within the relevant period and the relevant local planning authorities are informed. (legislation.gov.uk) That procedure was followed here. The correction order says the applicant asked in writing for errors and omissions in the 2025 order to be corrected, and that the Secretary of State informed the relevant local planning authorities before making the order. **What it means:** this is a built-in legal repair tool, not an informal tweak slipped in after the event. (legislation.gov.uk)

Some of the changes are exactly the kind you would expect in a long legal document. A wrong cross-reference was changed from Schedule 14 to Schedule 12, a duplicated “in in” became “in”, “principle” was corrected to “principal”, and a Thames Water contact email was fixed. The schedule also adds a noise insulation scheme document to the certified papers and makes several wording changes around noise-related definitions and eligibility. (legislation.gov.uk) At first glance, that may sound fussy. But statutory instruments are the place where exact legal wording is set out, and certified documents are there to pin down which version of a plan or scheme actually carries legal weight. If that wording is off, arguments can follow about what the consent really allows or requires. (parliament.uk)

The biggest correction is not a typo at all. The order inserts a new article 29A on the power to override easements and other rights for authorised activity within the order limits, while also stating that compensation is payable and can ultimately be enforced against the undertaker if someone deriving title from the undertaker fails to pay. The correction order also removes and renumbers parts of article 29 and updates related protective wording elsewhere so the new article 29A fits properly into the rest of the order. (legislation.gov.uk) **What this means for you:** if you want to know whether a correction order matters in real life, this is where to look. Changes about easements, land rights and compensation are not just punctuation. They affect how powers over land can be used and what safeguards follow with them. (legislation.gov.uk)

There is also a wider media-literacy lesson here. Legal documents often hide their most important points inside dry phrases such as “omissions”, “certified documents” or “relevant planning authority”. But those phrases tell you who must be told, which papers carry legal force, and what people can challenge if a dispute ends up in court. That is why correction orders deserve more attention than they usually get. (legislation.gov.uk) If you are reading a future runway headline, three questions will help. Is this a fresh consent or a correction? Who asked for the change? And does the new text alter land rights, compensation, environmental conditions or the documents that have been certified? In the Gatwick case, the January 2026 instrument was a formal correction order to the 2025 consent, and the source note shows the later republication was about how that correction instrument was classified for publication rather than a second decision on whether the project should exist.
