London's Planning Shake-Up Is Reshaping Where Developers Dare to Build

Sadiq Khan's office confirmed last week that the Greater London Authority has approved 14 major residential schemes since April, totalling just over 6,200 homes — more than double the quarterly figure recorded in the same period in 2024. The surge follows revisions to the London Plan's density matrix that came into force in March, relaxing height restrictions on sites within 800 metres of Elizabeth line stations and stripping back the sequential test that had long stalled applications near town centres.

The timing matters. Labour's nationally mandated housing targets — 88,000 net additional homes annually across England — are hitting London councils just as construction financing has marginally eased, with the Bank of England base rate sitting at 3.75 percent after two cuts since January. Developers who spent 2024 shelving viability reports are now dusting them off.

The Elizabeth Line Effect Spreads East

Nowhere illustrates the shift more sharply than Ilford. The London Borough of Redbridge granted outline planning consent in June for a 1,450-unit mixed-tenure scheme anchored around the Crossrail Place entrance on Clements Road — a site that attracted just one pre-application inquiry in the previous three years. The developer, a joint venture between Grainger plc and a TfL commercial arm, is targeting a first phase of 340 build-to-rent units, with shared ownership homes accounting for 35 percent of the overall mix.

Meanwhile, Meridian Water in Enfield — a 10,000-home masterplan that has lurched through planning committees since 2017 — finally received a funding commitment in May when the new Homes England strategic partnership allocated £340 million toward infrastructure. That money unlocks the Meridian Water Overground station that Network Rail had refused to progress without confirmed development density around it. The first 725 homes on the Edmonton Green-adjacent plots are now expected to break ground in the second quarter of 2027.

Contrast those outer-zone movements with what is happening in Zone 2. Southwark Council rejected Berkeley Group's revised Elephant Park Phase 4 application in May, citing the developer's revised affordable housing offer of 22 percent — well below the council's 35 percent threshold. Berkeley's stock dropped 4.2 percent on the day of the decision. The rejection crystallised a tension that has been building since the government's revised National Planning Policy Framework last autumn: national targets push volume, but local policy still controls tenure mix, and the two objectives regularly clash.

Where the Money Is Moving

Property consultancy CBRE's London residential pipeline monitor, published in June, found that planning applications in Zones 4 to 6 rose 31 percent year-on-year in the first half of 2026, compared with a 7 percent decline in Zones 1 and 2. Average asking prices along the Hayes and Harlington stretch of the Elizabeth line now sit at £415,000 for a two-bedroom flat, up 9 percent since January 2025 — slower than the central-London headline but considerably ahead of the 2.3 percent national average tracked by Halifax.

Waltham Forest is emerging as a secondary hotspot. The borough approved six schemes of more than 100 units between January and June, partly because its recently adopted local plan explicitly supports tall buildings — up to 24 storeys — within the Walthamstow town centre boundary. One scheme, a 260-unit tower on the corner of Hoe Street and Forest Road, cleared committee in April with a 40 percent affordable housing commitment after the developer negotiated a reduced section 106 contribution on public realm works.

Buyers hunting value should watch the Stratford-to-Ilford corridor closely over the next six months. Several schemes approved this quarter will launch sales in the autumn, and agents at Savills' Canary Wharf office are already reporting elevated off-plan inquiries from buyers priced out of Forest Gate and Bow. For investors, the revised stamp duty surcharge — now 5 percent on additional dwellings above £40,000 — makes build-to-rent schemes with institutional landlords a more attractive entry point than direct ownership for those working with leveraged finance. The policy environment remains volatile, but the planning decisions of this spring have drawn a fairly clear map of where the capital's next housing cycle is being built.
