Net Zero Teesside Amendment Order 2026 Explained
If you glanced at this statutory instrument on legislation.gov.uk, you could be forgiven for thinking it was little more than paperwork. The Net Zero Teesside (Amendment) Order 2026 was made on 28 July 2026 and came into force on 29 July 2026. On paper, it changes just two measurements in an earlier order from 2024. But this is exactly the kind of dry-looking document worth slowing down for. When we put it into plain English, we can see something bigger: major infrastructure is not approved once and then left untouched. It can be adjusted through formal legal steps, even when the change is described as non-material.
A development consent order, usually shortened to DCO, is a special kind of planning permission used for major infrastructure under the Planning Act 2008. Rather than going through the ordinary local planning route, very large schemes are often approved through one detailed order that sets out what can be built and the limits it must stay within. In this case, the 2026 Order does not create a brand new project. It amends the existing Net Zero Teesside Order 2024. That matters because the legal permission already exists; the question here was whether a small adjustment could be made inside that permission.
The change was requested under the Infrastructure Planning (Changes to, and Revocation of, Development Consent Orders) Regulations 2011. The applicant asked the Secretary of State for what the law calls a non-material change, which is planning language for an amendment judged small enough that it does not alter the scheme in a fundamental way. The Order says the Secretary of State considered the application and the responses to the required publicity and consultation before agreeing to it. The wording is formal, but the message is simple: even a limited amendment still has to go through a legal process, and ministers must decide whether the final change stays close to what was originally proposed.
The amendment sits in Schedule 15 of the 2024 Order, inside the design parameters. Two figures are changed. The inner diameter of the heat recovery steam generator stack rises from 6.5 metres to 9.0 metres, and the inner diameter of the absorber stack rises from 6.6 metres to 7.0 metres. **What this means:** the Order is changing the approved width inside two stacks, not rewriting the whole project. These are technical measurements, but in planning law technical measurements are part of the permission itself. If the approved numbers change, the legal document has to change too.
That may sound fussy, but it is one of the clearest lessons in infrastructure planning. Big projects are governed by drawings, schedules and design limits. If the consent says one thing and the build needs another, developers cannot simply treat the paperwork as optional. So a small amendment can matter for a very practical reason: it keeps the authorised design and the legal consent aligned. For readers, this is a reminder that planning law is not only about whether a project is allowed. It is also about the exact terms on which it is allowed.
It is also worth being clear about what this Order does not do. It does not cancel Net Zero Teesside, replace the 2024 consent or start a fresh planning battle from scratch. The explanatory note published with the legislation says this is an amendment to an existing development consent order following an application for a non-material change under Schedule 6 to the Planning Act 2008. That distinction matters because headlines can make every planning document sound dramatic. Sometimes the real story is narrower and more instructive: a project already has consent, and the state is updating one part of that consent through a formal route set out in law.
The Order was signed on 28 July 2026 by John Wheadon, Head of Energy Infrastructure Planning & Innovation at the Department for Energy Security and Net Zero, and it took effect the next day. For most people, that will not feel like front-page news. Still, this is how public decisions often move: through technical text, measured changes and quiet legal instruments. If you are trying to get better at reading government documents, this is a strong example to start with. We do not need every statutory instrument to be dramatic to see why it matters. Sometimes a shift from 6.5 metres to 9.0 metres tells you something bigger about how infrastructure is planned, checked and altered in public view.
