England’s most significant restructuring of local government in half a century is underway. Framed as a governance reform, the shift from two-tier to unitary authorities across large parts of southern and eastern England risks being misunderstood by the market as administrative housekeeping. It is not.

For residential development lenders, local government reorganisation (LGR) is a material, near-term credit issue. It directly affects the planning system – and planning, in turn, is the single most important driver of value in residential development.

Put simply: if you are lending against residential land, you are lending against a planning outcome. And right now, across many of England’s most active housing markets, that outcome is becoming less certain.

A planning system in transition

The areas undergoing reorganisation including Surrey, Hampshire, Essex, Kent and others represent some of the most supply-constrained and policy-sensitive housing markets in the country. Over the next two years, dozens of councils in these locations will be abolished and replaced with new unitary authorities. The transition period is where the risk sits.

While existing councils remain legally responsible for planning decisions until vesting day, their capacity is inevitably diluted. Senior staff are focused on restructuring, policy teams are paused, and institutional continuity begins to fragment. The result isn’t a halt in decision-making, but a weakening of the clarity and consistency that underpins it.

Planning policy will lag. In many cases it already is. As authorities move toward abolition, the incentive – and ability – to progress new local plans diminishes. What replaces them is a more discretionary, case-by-case system, where outcomes are less predictable and more open to negotiation.

For lenders, that shift matters. Uncertainty in planning translates directly into uncertainty in value.

The fragility of development appraisals

Residential development viability is already finely balanced. Build costs remain elevated relative to pre-2022 norms, debt is more expensive, and sales values in many locations have yet to fully recover. Margins, in other words, are tight.

In that environment, relatively small changes in planning assumptions can have outsized effects.

Take affordable housing. The proportion of homes that must be delivered at a discount is set locally and varies significantly between authorities. As multiple districts merge into a single unitary structure, those policies will eventually be harmonised. There is no guarantee that harmonisation will land at the lower end of the existing range.

For schemes yet to secure consent, that introduces a clear risk: an appraisal based on a 25% affordable housing assumption may be tested against a 35% requirement by the time it is determined. The impact on residual land value – and therefore on loan security – is immediate.

A similar dynamic applies to infrastructure contributions, particularly the Community Infrastructure Levy (CIL). During the transition period, new authorities inherit a patchwork of charging schedules from predecessor districts. Rates can vary widely across small geographies, and the process of unifying them takes years.

For sites near former district boundaries, the applicable rate may not be clear at the point a loan is underwritten. That is not a marginal issue. On larger schemes, differences in CIL assumptions can translate into six-figure swings in cost.

A new counterparty risk

Less discussed, but equally important, is the transfer of planning obligations.

Section 106 agreements – the legal backbone of most larger residential schemes – move automatically to the successor authority at vesting day. But while the obligation transfers, the context does not. The new authority inherits a contract it did not negotiate, often without the institutional memory behind its drafting.

That matters where agreements include review mechanisms, deferred contributions, or flexibilities designed to respond to viability pressures over time. A new authority, particularly one under financial strain, may take a more rigid interpretation of those provisions – or seek to reopen them altogether.

For lenders, this introduces a subtle but real counterparty risk. The entity you underwrote against at origination is not necessarily the one you will be dealing with mid-scheme.

Delay as a structural issue

Alongside policy uncertainty and contractual risk sits a more practical challenge: delay.

Planning departments in affected areas are already experiencing capacity constraints. Staff attrition, recruitment freezes, and diverted management attention all contribute to slower decision-making. Statutory timelines become harder to meet, and the gap between application and determination widens.

For development finance, time is not a neutral variable. Delays to consent push back starts; delayed starts extend loan terms; extended terms increase exposure. Where exit strategies are linked to planning milestones, timing slippage becomes a direct credit concern.

Valuation in an uncertain environment

Valuers are responding as they should by recognising and disclosing increased uncertainty.

Where planning policy is in flux, cost assumptions are unclear, and counterparties are changing, it is entirely appropriate for valuations to carry wider ranges or explicit caveats. But for lenders, that has implications.

A headline loan-to-value ratio derived from a valuation with elevated uncertainty is not equivalent to one based on stable assumptions. Treating the midpoint as a fixed point, rather than a range, risks overstating the strength of security. This is not a future risk

One of the more dangerous misconceptions around LGR is that its effects are long-term. They are immediate.

The transition period is already underway. Planning policy is already ageing. Decision-making is already slowing. Developers are already adjusting behaviour – in some cases accelerating applications to secure consent under existing regimes, in others delaying in anticipation of more favourable negotiations. Lenders need to be equally responsive.

A more disciplined approach to risk

None of this suggests that lending in LGR areas should stop. But it does require a more forensic approach.

Understanding whether a site sits within a transition area is now a basic diligence point. Beyond that, greater scrutiny is needed around planning assumptions: which authority will determine the application, under what policy framework, and at what point in the transition timeline.

There is also a strong case for recalibrating risk tolerance. Additional headroom on loan-to-value ratios, closer interrogation of affordable housing and CIL assumptions, and more active monitoring of Section 106 triggers are all proportionate responses to a less certain environment.

Crucially, credit committees should be asking more targeted questions. Not just whether planning consent is in place, but how robust the assumptions behind it are in the context of structural change.

A governance story with real credit consequences

Local government reorganisation may sit within the language of policy reform, but its effects are being felt in the fundamentals of development viability.

In a market where margins are already thin, the additional layer of uncertainty it introduces is not academic. It has the potential to determine whether schemes proceed, whether values hold, and whether loans perform as expected. For lenders, this is not background noise. 

It is credit risk and it needs to be treated as such.
