A house is built before the road is ready
Drive to the edge of almost any growing town in South Kesteven and the pattern becomes familiar quickly. A new estate sits largely finished — gardens seeded, bins out, cars on drives — while the access road tapers into a muddy track, the nearest primary school is already at capacity, and the GP surgery a mile away has a waiting list that pre-dates the first brick being laid. Nobody planned for this outcome. Yet it keeps happening.
South Kesteven has absorbed considerable and sustained growth across several settlements at once. Bourne's population rose by roughly 16% between the 2011 census and a 2019 estimate — from 14,456 to around 16,780 — and Grantham has carried even larger commitments through major urban extensions. Schools, sewers, roads, and health facilities are supposed to arrive in step with the housing. In practice, the sequencing is rarely that tidy.
This is not simply a matter of councils moving slowly or developers cutting corners. It reflects something structural: the authority that grants planning permission — South Kesteven District Council — does not control the agencies that build roads, fund school places, or invest in utility networks. Those decisions sit elsewhere, with Lincolnshire County Council, statutory undertakers, and national bodies operating on their own timescales and budgets.
So who actually decides how South Kesteven grows — and, more to the point, in what order do things happen?
What an Infrastructure Delivery Plan is actually for
Think of an Infrastructure Delivery Plan as the answer to a single, practical question: in what order does everything need to be built? Before the first house can be occupied on a new Grantham urban extension, someone must have confirmed that the road junction can cope, that the nearest primary school has places, that the sewage network has capacity. An IDP is the statutory evidence-base document — a formal requirement for any Local Plan in England — that is supposed to map those dependencies explicitly.
In its working form, an IDP assigns infrastructure to one of three tiers: critical (must be in place before occupation), necessary (required by a defined phase of development), or desirable (aspirational but not a condition of consent). For each item it records the responsible body, an estimated cost, and the funding route — typically a Section 106 agreement or a Community Infrastructure Levy contribution negotiated at the point of planning permission. This is what South Kesteven District Council's 2025 IDP is designed to contain: a maintained schedule tying each phase of approved growth to specific delivery commitments.
SKDC produced the 2025 document against the backdrop of the Planning and Infrastructure Act 2025, which significantly reformed how such documents are produced and the weight they carry in planning examinations. That reform raised the stakes: the IDP now operates within a tighter statutory framework that demands more rigorous evidence of deliverability, not simply intent.
What an IDP cannot do is guarantee the outcome. It may record that a junction upgrade is critical and name a responsible body — but whether that body programmes the work on the IDP's timetable is a separate question entirely. The document coordinates intention across agencies that SKDC does not direct. That gap between coordination and control is where the difficulty begins.
The split authority behind every planning decision
The split begins with a simple statutory fact: South Kesteven District Council — 56 elected councillors across 30 wards — is the Local Planning Authority. That means SKDC decides whether a planning application is approved or refused, and it is responsible for producing the IDP. What it does not hold is the authority to act on much of what that document contains.
Lincolnshire County Council controls the highways network. When a new estate on the edge of Grantham requires a junction upgrade or a new access road, it is LCC — not SKDC — that must programme and fund the works. LCC also carries capital responsibility for school provision: the decisions about where a new primary school gets built, and when, sit with the county, not the district. These are the two infrastructure categories most immediately strained by housing growth, and neither falls within SKDC's direct authority.
Utility networks are a further remove still. Water supply, sewage capacity, and electricity connections are managed by private regulated companies — statutory undertakers — that SKDC can consult during the planning process but cannot direct. A water company's investment schedule responds to its own regulatory framework, not to a district council's growth timetable.
The result is a structural misalignment that is not the product of poor management or inter-authority rivalry. It is simply how English local government is organised. SKDC approves the homes; Lincolnshire County Council builds the roads; the utility companies upgrade the sewers — each operating on separate budgets, separate timescales, and separate accountability chains.
The IDP exists, in part, to bridge this gap through coordination. But coordination, as any engineer would recognise, is not the same as control.
How developers are made to pay — and why timing matters
Money enters the picture at the moment SKDC grants planning permission — and not before. Two legal instruments govern how it flows from developers into infrastructure: Section 106 agreements and the Community Infrastructure Levy.
A Section 106 agreement is negotiated case by case. For a large Grantham urban extension, it might specify that the developer must contribute a fixed sum toward a new road junction before the hundredth dwelling is occupied, or fund a primary school land transfer at a defined phase. The condition is binding — but only SKDC can enforce it against the developer. Whether LCC then delivers the junction on time, or the school opens when families arrive, depends on a separate set of decisions entirely outside SKDC's hands.
The Community Infrastructure Levy works differently: a standardised charge per square metre of floor space, paid into a pooled fund. Where and when that money is deployed — which junction, which GP surgery, which cycle path — is a further governance decision, made after the permission is granted and the levy collected.
Both mechanisms share a structural quirk that matters enormously to residents of a half-built estate: receiving the contribution and completing the infrastructure are not the same event. The gap between them can stretch to years. In the meantime, families in Bourne or on Grantham's southern edge absorb the shortfall — using roads, school places, and surgery appointments that were not designed to carry the extra load.
Where the plan meets the ground
The gap between IDP intent and delivered infrastructure has a lived texture in South Kesteven that regional planning coverage makes visible. Three types of dispute recur with enough regularity to suggest a pattern rather than isolated misfortune.
Sewage capacity is one. Under current UK law, a water company cannot refuse a connection to its network on grounds of capacity alone — meaning that even where drainage objections are raised, the connection proceeds and the network absorbs the load. Local planning coverage records this dynamic playing out in the district, with capacity concerns raised and then, effectively, set aside.
Housing approval against community concern is another. A 213-house estate was approved in the district despite objections — the kind of decision where the IDP's phasing schedule should, in principle, have already settled the capacity question. Where delivery commitments rest with agencies working to separate timetables, the objection cycle simply repeats at the next application.
School redevelopments have attracted a third category of dispute, with objections focusing on flooding, traffic, and parking — the same infrastructure-readiness concerns that sequencing frameworks are designed to pre-empt before consent is granted.
Taken together, these disputes reveal that the structural problem is not theoretical in South Kesteven. It surfaces in committee rooms, in parish council responses, and in the lived experience of residents waiting for a road, a school place, or a functioning drain. What gets sequenced first, and what is left to catch up, reflects choices made — and contested — across multiple levels of government.
What happens if the council making the plan ceases to exist
Underlying all of this is an open institutional variable that the 2025 IDP cannot resolve on its own. Lincolnshire councils are reportedly setting aside funds — £200,000 in at least one reported case — to plan for a potential restructuring into unitary authorities. If South Kesteven District Council were dissolved or absorbed into a larger body, the institution currently holding the IDP would cease to exist in its present form.
The practical consequences would not be abstract. Existing Section 106 obligations and CIL allocations would need to transfer to a successor authority or be renegotiated. Development permissions already granted under SKDC's Local Plan would carry infrastructure conditions into whatever governance structure replaced it — but whether those conditions would be enforced with the same priority, and by whom, is genuinely uncertain. A unitary structure might, in theory, resolve the split-authority problem that runs through every section of this article: highways, schools, and planning permissions would sit under a single roof. It might equally create new misalignments at a different scale.
What is simply true is that the 2025 IDP was finalised in a period when the body commissioning it may not be the body implementing it. For anyone trying to hold a delivery timeline to account — a parish council, a school governor, a resident on a half-built estate — that is worth holding in mind.
