London’s political reset: What the 2026 elections mean for real estate

The 2026 London local elections produced the most significant reshaping of borough politics in a generation. Labour’s dominance across much of inner London has come to an end. Nine previously Labour-controlled councils have fallen into no overall control, and the Green Party emerged as a serious political force in the capital’s urban core. The Greens in Hackney, Lewisham, Waltham Forest, Haringey, Lambeth, Barnet, Brent, Enfield and Southwark either in control, are the kingmakers or will heavily influence decision-making over the next four years.

For the real estate and built environment sector, this is not simply a story about political volatility. It is a structural change to the environment in which planning, regeneration and housing delivery operates.

For more than a decade, many developers worked within relatively stable borough ecosystems. Political leadership was largely predictable, planning committees broadly aligned with administration priorities, and major regeneration projects could often progress through established channels of engagement. In many Boroughs (but not all), that model could now break down.

The rise of the Greens is likely to increase pressure on the development industry, particularly around affordable housing, retrofit, embodied carbon and estate regeneration. Schemes previously judged primarily on housing numbers and viability may now face greater scrutiny around environmental performance, social value and community impact. Opposition to tall buildings, demolition-based regeneration and perceived “luxury-led” development is likely to intensify in some boroughs. There will be less understanding of why developments cannot deliver at policy levels of affordable housing, and even less trust of viability assessments.

Yet the implications are more nuanced than simply local politics becoming more anti-development. Many newly influential Green councillors are not opposed to growth itself; they are opposed to development perceived as profit driven, failing local needs or poorly explained. That creates risk for some schemes, but opportunity for others.

The expansion of no overall control (NOC) councils is equally significant. In NOC boroughs, planning decisions become more political and less predictable. Coalition-building, informal alliances and ward-level dynamics matter more. Planning committees are likely to become more fragmented, with councillors under greater pressure from activist groups and hyper-local campaigns. Developers may no longer assume that officer recommendations or historic political relationships will guarantee outcomes.

Paradoxically, schemes that have not yet secured consent may now have an advantage. Projects still in formation could reset engagement strategies before positions harden. Early consultation, visible community benefits and direct engagement with councillors across multiple parties will become essential. Developers who continue to rely on legacy assumptions about borough leadership structures risk finding themselves exposed.

This new landscape will also strengthen the role of City Hall. If borough-level decision-making becomes slower, more fragmented or increasingly resistant to housing delivery, pressure will grow for a more interventionist Mayor of London. Securing anything close to London’s housing need will mean more mayoral call-ins, stronger strategic planning powers or renewed debate around zoning.
The political consequences may extend beyond planning. London’s results will intensify debate within Government about housing targets, infrastructure investment and economic growth. They also reinforce a wider national trend towards fragmented politics, where traditional party loyalties are weakening and local identity is becoming more important.

For investors and developers, the message is clear. London has entered a new political era. Success will depend less on transactional planning processes and more on credibility, trust and local legitimacy. Independent businesses, community partnerships and demonstrable public benefit are likely to carry greater weight than ever before.

The borough map has changed. The rules of engagement for development in many parts of London have changed with it.
