Permission for 246 flats on the Cumberland Street car park dies on 11 October. The developer has applied to dig trenches to beat it, and is drafting a replacement.
Planning permission for a 21-storey block of 246 flats in Luton town centre runs out on 11 October 2026, and the developer has five weeks to get a spade in the ground.
The permission covers the empty site off Cumberland Street, next to Park Viaduct. Luton Council granted it on 11 October 2023 under reference 22/00211/FUL. Condition 1 gave the standard three years to start work.
Nothing has been built. The land is currently in use as a temporary car park and for storing construction materials.
So the applicant, JRL Property, has spent the summer filing paperwork designed to start the scheme legally before the clock stops. Its planning agent, Iceni Projects, set out the reasoning in a covering letter to the council on 23 July:
“The Applicant is seeking to lawfully commence development before the expiration date via the carrying out of initial enabling works related to the digging and laying of services for the substation which is required on the Site.”
That is the whole plan. Dig the trenches, and the permission stays alive.
What has been applied for
Four applications have gone in on the site since late July, all through the same agent.
- 26/00788/AMEND, approved, added a phasing plan to the permission so that a “Phase 0” could exist at all.
- 26/00790/AMEND, approved on 21 August, reworded pre-commencement conditions 3, 15, 17 and 25 so Phase 0 does not trigger them.
- 26/00787/DOC, approved, discharged the archaeology condition.
- 26/00899/AMEND, still undecided, goes back to condition 25 to allow the trench digging itself.
The council’s target date for deciding the last of those is 22 September 2026, three weeks before the permission expires. It is a delegated decision, so councillors will not vote on it. The case officer is Abigail Chapman.
Iceni told the council what happens next once the trenches are dug:
“A Certificate of Lawfulness application will be submitted to confirm that the permission has been lawfully implemented before its expiration and is extant.”
Why condition 25 is the sticking point
Condition 25 exists because of what is under the site. The land sits over a Principal Aquifer in the chalk and a shallower Secondary ‘A’ Aquifer, inside a Source Protection Zone 1. The nearest drinking water abstraction point is 42 metres to the south west.
The condition bars any excavation until an intrusive ground investigation, a risk assessment and a method statement have been approved by the council in consultation with Affinity Water, and it requires Affinity Water to be given 15 days’ notice before digging.
The developer’s geotechnical consultant, Card Geotechnics, argues the Phase 0 trenches do not need any of that. Its technical note, dated 20 August, says the service trenches will go down about 1.1 metres, while the top of the chalk is at least 1.6 metres down, so the works will not reach the Principal Aquifer.
“Given that the Phase 0 excavations will remain above the Principal Aquifer, formal notification to Affinity Water is not considered necessary at this stage.”
The council’s own environmental officer agreed. In a memo dated 1 September 2026, Environmental Engineer and Scientist Jonathan Pyke wrote: “We support this approach and therefore have no objection to the amendment.”
The consultant’s note adds that if contamination turns up while the trenches are being dug, a discovery strategy kicks in and the risk is reassessed.
A replacement scheme is already being drawn up
While all this was going on, the same agent asked the council on 17 August for an environmental screening opinion on a new application for the same 0.3 hectare site.
That request, reference 26/00878/EIASCR, describes:
- up to 250 homes, four more than the current permission
- a single block up to 21 storeys, the same height as approved
- 1,090 square metres of amenity space
- 25 car parking spaces and 72 cycle spaces
The council has not yet decided whether that scheme would need a full environmental impact assessment. When the same site was screened in December 2021, the council said no assessment was needed.
The site has been through this before. It was cleared of commercial and warehouse buildings before 2018, won permission for 175 homes in 2019, then for 246 in 2023.
What it means for you
Luton is short of housing land. The council’s own five year housing land supply statement puts the borough at 4.64 years against a five year requirement, a shortfall of 414 homes, measured from 1 April 2025. Its annual housing need under the standard method is 1,095 homes. A permission for 246 flats lapsing in the town centre matters to that sum, which is part of why an application like this one gets waved through on paper rather than fought over.
For people living and working nearby, the practical points are narrower:
- If the trenches go ahead, expect a short spell of excavation work on the Cumberland Street site, not the start of a tower. The consultant describes them as shallow service trenches for a substation.
- The bigger construction phase, Phase 1, still has to clear the full set of conditions, including a construction environmental method plan covering working hours, wheel washing, dust control and hoarding.
- If you want to comment, the case is open on the council’s planning register. As of today no public comments have been lodged. Non-material amendments are decided by officers and are not formally advertised to neighbours.
