Why Pennycook paused the City of London Local Plan

If planning language can feel like another dialect, this is a good moment to slow it down. The government has stepped into the City of London’s Local Plan examination: in a letter dated 25 June 2026, Housing and Planning Minister Matthew Pennycook told the Planning Inspectorate to revisit one disputed issue before the plan can move on. The GOV.UK publication page carrying that intervention is dated 16 July 2026. (gov.uk) The issue is not the whole plan from scratch. The minister says concerns were raised during the examination about the plan’s possible effect on the Tower of London and its World Heritage status, so he wants more scrutiny before inspectors finish their work. (gov.uk)

A Local Plan is, in plain English, the rulebook a council uses to decide what can be built, where it can go and what limits apply. Planning Inspectorate guidance says local plans shape land for homes, offices, shops and other development, and they are then used when planning applications for individual schemes are decided. (gov.uk) For the Square Mile, that rulebook is the City Plan 2040. The City of London Corporation says it sets the vision, strategic priorities and policies for development in the area up to 2040, and that it was submitted to the Secretary of State for examination on 29 August 2024. (cityoflondon.gov.uk)

What the minister has done here is quite specific. Using powers under section 20(6A) of the Planning and Compulsory Purchase Act 2004, he told the inspectors not to issue their final report yet and not to keep considering other parts of the plan while this one question is revisited. (gov.uk) What this means in practice is simple: the inspectors now have to test whether Historic England’s alternative proposal for tall building contours would strike a better balance than the current Figure 15 in the City Plan. They have been told to compare the economic and heritage effects of both approaches, hold further hearing sessions for parties who commented on heritage and tall buildings, and then produce written findings in a post-hearings letter. (gov.uk)

This matters because inspectors are not there to wave a plan through. Planning Inspectorate guidance says their job is to test whether a submitted plan is legally compliant and ‘sound’ - meaning, in summary, positively prepared, justified, effective and consistent with national policy. (gov.uk) If you are wondering why another hearing matters, the same guidance gives the answer. People who objected to the final draft at Regulation 19 stage have a legal right to appear and be heard, and the minister’s direction specifically creates another chance for those who made representations on heritage and tall buildings to take part. (gov.uk)

The row at the centre of this case is technical, but the basic idea is teachable. The City of London’s own explanatory note says the draft plan differs from the adopted 2015 Local Plan by mapping where tall buildings may be appropriate and what heights they could reach in much more detail. It also says the contour lines should be understood as frameworks to guide future tall building development, not as a fixed three-dimensional shape. (cityoflondon.gov.uk) That does not mean the heritage question disappears. The same City note records objections arguing that the proposed City Cluster could harm the setting of St Paul’s Cathedral and the Outstanding Universal Value of the Tower of London World Heritage Site, while the minister’s letter says he wants reassurance that the plan protects the Tower adequately without unduly restricting economic growth. (cityoflondon.gov.uk)

This is also a reminder that late-stage planning arguments do happen. The City of London examination had already held hearings beginning in March 2025, including dedicated sessions on heritage and tall buildings in June 2025, and a consultation on modifications ran from 15 December 2025 to 6 February 2026 before this intervention landed. In other words, the plan was already well advanced when the dispute sharpened. (cityoflondon.gov.uk) Seen that way, the minister is not reopening every chapter of the City Plan 2040. He is pressing pause on one narrow but culturally significant test: whether growth in the Square Mile can be planned without putting one of the country’s best-known heritage sites at greater risk. (cityoflondon.gov.uk)

So where does this leave the plan? Not cancelled, and not adopted. The City of London Corporation says the scope of the extra work is confined to Historic England’s alternative proposal on tall building contours, and the minister says his directions should be acted on urgently so the City Plan is not delayed more than necessary. (cityoflondon.gov.uk) For you as a reader, the bigger civic lesson is that planning policy is not just about skylines or architects’ drawings. A Local Plan shapes the decisions that follow on offices, homes, transport and protected places, so a ministerial intervention at this stage can change how a city grows. After the extra hearings and post-hearings letter, the inspectors can return to the wider examination process, which normally ends with a final report and then an adoption decision by the local authority.
