Planning in England has shifted again. For apartment developers, the winners will be those who read the national signals, pick local battles wisely and move faster than their competitors.
National Picture: Targets are Back, Delivery Pressure is Real
The revised National Planning Policy Framework was updated on 7 February 2025 following reforms announced in December 2024. The government has re-energised the housing target regime as part of its 1.5 million homes ambition this Parliament. For developers, that means a renewed emphasis on plan-making, a clearer justification for density in urban areas and more Secretary of State interventions to push schemes through.
Is delivery on track? Independent trackers suggest the pledge requires sustained acceleration in permissions and starts, and warn that recent application volumes are below what is needed. Treat this as both a risk and a chance: authorities under pressure to meet targets can be more open to well-designed urban infill and intensification.
Permitted Development Rights: Using Class MA Where it Still Works
Class MA enables conversion from Use Class E to C3, subject to prior approval criteria and national space standards. For apartments, the key is quality and viability. Since April 2021, PD homes must meet the nationally described space standard and provide adequate natural light, which raises build quality and caps unit counts in tight buildings. Treat PD as a tool for the right assets rather than a volume game.
The Article 4 Fightback on PD in City Boroughs
Many urban councils are pushing back with Article 4 Directions that remove Class MA in defined areas. Islington confirmed six new Article 4 Directions in July 2025, effective 1 September 2025, withdrawing Class E to C3 PD across swathes of the borough to protect high streets and employment space. The message is clear: do not assume PD in core London or other tight city centres. Check Article 4 coverage early and model a full planning route.
Targeted Densification: How to Make the NPPF Work for Apartments
Lean on urban regeneration language. The updated NPPF supports brownfield and urban intensification where design quality is high. Couple height with design codes and townscape analysis to make density palatable.
Evidence need with updated demographics. Population growth projections and continued net migration, even at lower levels than 2022–2023, help justify apartment delivery near jobs and transport.
Use Section 106 pragmatically. In a market of higher financing costs and cost inflation, viability evidence remains critical. Reference BCIS tender price expectations when negotiating affordable housing mix and tenure.
Commercial Conversions: What Still Pencils In 2025
Deep floorplate offices with reasonable floor-to-ceiling heights and window geometry can still convert into good single-loaded or duplex apartments, especially outside Article 4 zones.
Retail-plus-upper floors in secondary town centres suit maisonettes and micro-two-beds if acoustic and servicing solutions are strong.
Light industrial and creative spaces are often politically sensitive. Expect design scrutiny and push for a full planning application rather than PD even if technically available.
How the Rental Market Should Inform Your Planning Strategy
Rents are rising more slowly and affordability is binding. Average new-let rents rose 2.8% in the year to April 2025 and are on track for 3 to 4% this year, while several forecasters have trimmed expectations further. That makes apartment depth of market more important than chasing record headline ERVs. Prove the absorption story with hard evidence near universities, hospitals and transport.
Engage Early on Design Codes, Second Staircases & Height
Where boroughs have adopted design codes, align proposals tightly and document the compliance story. If you are over 18 metres, show how the second staircase enhances safety and lets you deliver more homes by increasing resident confidence rather than treating it as lost NIA. Tie that into your townscape narrative and day-one management plan.
Planning Heat-Risk into the Scheme
With overheating risk now a mainstream planning and building control concern, apartments that demonstrate robust Part O compliance and passive cooling strategies tend to move faster through condition discharge. Bring shading, ventilation paths and thermal modelling into the planning pack.
Actionable Workflow for 2025 Schemes
Policy scan. Map NPPF changes, local plan status and Article 4 coverage before you even open Excel.
Asset triage. Shortlist sites that combine transit, services and political will.
Pre-app early. Position height and density as tools to hit mandatory targets with exemplary design.
Compliance spine. Lock a second-staircase and Part O strategy into RIBA Stage 2.
Funding narrative. Pair planning momentum with BTR investor dialogues to secure forward-funding once a resolution to grant is in sight. Recent BTR investment resilience suggests capital is there for de-risked schemes.
The Developer’s Edge
In 2025, the edge comes from mastering policy details and anticipating compliance. There is political will to build, a planning framework that rewards urban density done well and a rental market that is still deep even if gentler on growth. The developers who thread those needles will deliver apartments that lease, appraise and exit.
