Key Points

• The NHS has warned that Asda’s proposed 1,510-home scheme in Park Royal, west London, could place further pressure on already stretched local GP services.
• The health body said nearby surgeries are already over capacity and that there is not enough primary care infrastructure locally to absorb the extra demand from new residents.
• The NHS has asked for an additional £2.15m in Section 106 funding to help deliver more primary care floorspace in the area.
• The proposed development is a partnership between Asda and Barratt London and includes a new 60,000 sq ft Asda superstore alongside the homes.
• Asda and Barratt London said the request is a routine part of the planning process and that they are working with the local NHS Integrated Care Board, the Old Oak and Park Royal Development Corporation, and other consultees.

Park Royal (West London News) July 21, 2026 — The NHS has warned that Asda’s proposed 1,510-home redevelopment at Park Royal in west London could intensify pressure on local healthcare services unless extra funding is secured for primary care provision.

As reported by Ciaran Nerval of Property Week, the NHS said the area’s GP surgeries are already “over capacity” and that the scheme would generate demand that existing facilities cannot properly absorb.

Why has the NHS raised concerns?

The NHS’s objection centres on the impact of the planned housing on local general practice capacity. In its letter to planning officials, the health body said there is

“not sufficient existing primary healthcare capacity locally to address demand generated by the development”.

It added that mitigation is needed and linked that to an extra £2.15m contribution toward the capital cost of delivering more primary care space.

The NHS also said that, without the contribution, the scheme would not comply with the local authority’s local plan. That position makes the healthcare issue a formal planning concern rather than only a service-level warning.

What is Asda proposing at Park Royal?

The Park Royal project is being brought forward by Asda and Barratt London. The plans would combine a new 60,000 sq ft Asda superstore with 1,510 homes on the site. The wider proposal is part of a mixed-use redevelopment and has not yet secured planning approval.

The scale of the housing element is central to the NHS concern because new residents would create more demand for nearby health services. The NHS has said the local infrastructure must be expanded if the development goes ahead.

What did the NHS say in its letter?

The NHS said, based on the latest data on primary care infrastructure capacity, there is not enough local capacity to accommodate the population growth expected from the scheme.

It said mitigation is required in the form of a financial contribution of £2.15m toward additional primary care floorspace. The health body also indicated that the payment should support capacity expansion rather than general spending.

The request was presented as part of planning compliance and healthcare planning, not as a rejection of the project outright. That means the development may still progress if the concerns are addressed through the planning process.

How have Asda and Barratt responded?

In a joint statement, Asda and Barratt London said the NHS request is a routine part of planning major housing developments in London. They said the NHS seeks healthcare contributions on “almost every major housing development” in the capital.

They also said they are working closely with the local NHS Integrated Care Board, the Old Oak and Park Royal Development Corporation, and other statutory consultees to move the scheme forward.

The companies said their aim is to help deliver much-needed homes alongside a new Asda store. Their statement indicates the developers are treating the NHS request as a negotiable planning matter rather than a fundamental obstacle.

What does the planning context look like?

The scheme sits within the wider Park Royal and Old Oak regeneration area, where major development proposals continue to shape the western side of London. OPDC has been working on broader masterplanning and development arrangements in the area, including major housing and commercial growth ambitions. That context helps explain why healthcare, transport, and infrastructure capacity are likely to remain central planning issues.

The NHS’s warning also fits a wider pattern in which large residential schemes are expected to contribute to local services before or alongside occupation. In this case, the contribution sought is specifically tied to primary healthcare floorspace.

Background of this development

Asda and Barratt London have been advancing a mixed-use scheme at Park Royal that would replace or redevelop the current site with a large superstore and more than 1,500 homes.

The project is taking place in an area already associated with long-running regeneration plans led by the Old Oak and Park Royal Development Corporation.

The NHS intervention is part of the standard planning scrutiny that large housing schemes often face when local services may come under pressure.

Prediction

If the development is approved with the NHS contribution included, the most likely result is that local health capacity will be expanded in step with the new homes.

For residents in Park Royal and nearby areas, that could mean less strain on GP services than would otherwise occur, although delivery of the extra floorspace would still take time. For the developers, the key impact is that planning approval may depend on agreeing the funding and any related healthcare mitigation measures.
