Housing minister intervenes in Three Rivers Local Plan

You’ll see a lot of planning terms flying around this week. Here’s the plain-English version: on 18 March 2026, Housing and Planning Minister Matthew Pennycook wrote to Three Rivers District Council with formal directions on its draft Local Plan. The letter, published on GOV.UK, sets required changes and a new timetable. (gov.uk)

A Local Plan is your council’s legal blueprint for where homes, jobs, schools, parks and transport will go over the next 15–20 years. At the “Regulation 19” stage, the council publishes a proposed submission plan and asks you to comment on its legal compliance and whether it is “sound” before it goes to an independent inspector. (gov.uk)

Why step in now? In the letter, the minister judges the draft as unsatisfactory because it doesn’t allocate all appropriate sites that could help meet housing need. He also highlights plan progress and delivery: Three Rivers’ adopted plan dates from October 2011, the 2023 Housing Delivery Test score is 30% (triggering the presumption in favour of sustainable development), and homes are far less affordable locally than the England average (12.3 versus 7.7).

What must change in the draft? The minister directs the council to modify the Regulation 19 plan to include, at a minimum, sites such as CFS26a Kings Langley Estate south, CFS21 Land at Rousebarn Lane, PCS4 East Green Street, PCS47 South of Little Oxhey Lane, NCFS12 Land East of Oxhey Lane and NCFS6 Land to East of Watford Road, with OSPF22 Batchworth Golf Course added if lease issues are resolved. Together, these changes are intended to lift allocations to roughly 85% of assessed need. (assets.publishing.service.gov.uk)

There’s also a firm timetable. Three Rivers must start a revised Regulation 19 consultation by Wednesday 31 July 2026 (for at least six weeks) and submit the plan for examination by Monday 30 November 2026. The council is told not to withdraw the plan, to report monthly on progress, to see it through examination, to publish the inspector’s recommendations and to consider adoption with any main modifications. It must also publish a revised Local Development Scheme by Tuesday 30 June 2026. (assets.publishing.service.gov.uk)

Let’s pause on the 85% figure. In practice, this acts as a floor. It signals that the next version of the plan should allocate more land for housing than the council had proposed, supported by updated evidence on infrastructure, design quality and environmental impacts. The aim is to produce a plan the inspector is likely to find legally compliant and sound. (assets.publishing.service.gov.uk)

A quick rewind helps. On 5 February 2026 the minister issued a holding direction under section 21A of the Planning and Compulsory Purchase Act 2004, pausing any move to adopt the plan while further action was considered. The new section 21 direction now replaces that holding step and sets out the specific modifications required. (assets.publishing.service.gov.uk)

Green Belt will be part of the debate. The minister’s earlier correspondence asked for a plan that reflects national policy on Green Belt release. Under the National Planning Policy Framework, Green Belt boundaries can only be changed in exceptional circumstances through the plan process, and decisions must weigh harms and benefits against the policy’s purpose of keeping land permanently open. (assets.publishing.service.gov.uk)

What this means when you take part: the next consultation is technical. When it opens, your strongest contributions will focus on whether the plan is legally compliant and “sound”, backed by evidence. If you think a site lacks school places, buses or drainage, say why and point to data-the inspector will test those points. (gov.uk)

What this means for the council right now: without an up‑to‑date plan, Three Rivers remains exposed to speculative, piecemeal applications decided at appeal, with less certainty over affordable housing and infrastructure. That’s why the letter sets deadlines and requires monthly progress updates to the department. (assets.publishing.service.gov.uk)

Keep these dates in your diary: the council can submit any exceptional reasons against intervention by Tuesday 25 March 2026; it must publish a revised Local Development Scheme by Tuesday 30 June 2026; consultation should begin by Wednesday 31 July 2026; and the plan must be submitted by Monday 30 November 2026. We’ll track each milestone with you. (assets.publishing.service.gov.uk)

Classroom idea for teachers and students: read the four‑page government letter together and highlight every time a legal power is named-sections 21, 21A, 27 and 15. Then match each power to a real‑world action in the letter, like “add sites”, “set deadlines” or “don’t withdraw”. It’s a practical way to read a primary source with real policy impact.
