IN Brief:
- Wiltshire Council granted planning permission on 5 November for Salisbury District Hospital's Diagnostic and Surgical Hub.
- The proposed facility includes five operating theatres, four endoscopy rooms, MRI and CT scanners, and patient recovery accommodation.
- Enabling works can progress, but main construction requires NHS England's approval of the full business case.
Wiltshire Council has granted planning permission for a new Diagnostic and Surgical Hub at Salisbury District Hospital, allowing preparatory work to progress on a development intended to replace ageing surgical facilities and expand the hospital’s diagnostic capacity.
The scheme is being developed by Salisbury NHS Foundation Trust, which confirmed the planning decision on 10 November 2026. Permission was issued on 5 November and covers the proposed building together with associated access and landscaping works.
The decision allows the trust to progress enabling works in preparation for construction, but the principal building programme cannot begin until NHS England has approved the project’s full business case. The trust expects that approval to be considered in the coming months.
The proposed facility, known as DASH, would accommodate five operating theatres, four endoscopy procedure rooms, an MRI scanner, and a CT scanner. Its surgical department is also planned to contain 30 patient pods for preparation and recovery around surgical procedures.
The building is intended to replace the hospital’s existing day surgery unit, which dates from the 1990s and has exceeded its expected operational life. The development would also provide additional diagnostic capacity as demand for imaging and related services continues to increase.
Bringing these activities together requires accommodation designed around the different clinical and engineering requirements of surgery, endoscopy, diagnostic imaging, and patient recovery. The proposed layout is intended to separate planned treatment from urgent and emergency services, reducing the extent to which elective activity is affected by demands elsewhere in the hospital.
The arrangement will require coordination between operating theatres, preparation areas, recovery facilities, and the circulation routes used by patients and clinical staff. These spaces perform different functions but must operate as a connected clinical facility when the building enters service.
Each of the five operating theatres will require the specialist engineering systems associated with surgical environments. Relevant considerations include ventilation, electrical resilience, medical gases, lighting, infection prevention, and the controls needed to maintain appropriate conditions during procedures.
The precise design and performance requirements depend on the clinical activities undertaken and the applicable healthcare engineering standards. Operating theatre ventilation, for example, must be considered in relation to room layout, equipment positioning, filtration, airflow, and the management of contamination risks.
Electrical systems present another important design requirement. Surgical and diagnostic activities depend on equipment that must operate reliably, with appropriate arrangements for maintaining essential services and supporting the safe use of clinical installations.
The hospital’s MRI and CT facilities introduce different equipment requirements. MRI scanners generate powerful magnetic fields and require controlled access arrangements, specialist installation procedures, and consideration of the surrounding building environment.
CT systems involve ionising radiation, making shielding and the protection of adjoining spaces relevant to the room design. Both types of scanner also require appropriate electrical supplies, cooling, equipment access, and commissioning arrangements.
The installation of major diagnostic equipment must therefore be coordinated with structural construction and the completion of the building envelope. Scanner dimensions, weights, and handling arrangements can influence the routes through which equipment is brought into the building and the sequence in which surrounding spaces are completed.
The four proposed endoscopy rooms will provide separate diagnostic and treatment accommodation. The hospital’s published plans also include recovery areas, waiting facilities, and supporting spaces for patients and staff.
The surgical department’s 30 patient pods are intended to accommodate patients before and after procedures, allowing preparation and recovery activities to be organised around the operating theatre programme. The hospital has also identified separate male and female recovery areas associated with the endoscopy facilities.
These arrangements affect both the internal layout and the distribution of building services. Clinical spaces must accommodate staff movement, equipment, patient transport, cleaning, and the separation of different activities according to the hospital’s operating requirements.
Construction on an occupied hospital campus introduces constraints that differ from those of a cleared development site. Patient transport, ambulance movements, servicing, staff access, and emergency routes must remain available as required while the works are undertaken.
Site preparation may therefore involve temporary access arrangements, the establishment of construction boundaries, and coordination with existing hospital infrastructure. The trust has confirmed that enabling works can progress following planning approval, but has not published a detailed programme identifying the specific activities authorised to begin.
Once the full business case is approved, the main construction programme will need to coordinate groundworks, structural construction, building services installation, internal fit-out, and the installation of specialist medical equipment. The sequence will be influenced by the hospital’s operational requirements and the construction methods selected for the development.
The installation and commissioning of clinical systems will be a substantial part of the later programme. Equipment, ventilation, electrical installations, and specialist spaces require testing and verification before they can be accepted for use, alongside the broader commissioning of the completed building.
The planning permission also covers associated access and landscaping works. These elements will be needed to connect the completed facility with the existing hospital estate and provide suitable routes for patients, staff, visitors, and servicing activities.
Salisbury NHS Foundation Trust has previously identified early 2027 as a possible construction start, subject to the required approvals. That remains an anticipated programme rather than a confirmed commencement date, and the latest planning update does not establish when main construction will begin.
Planning consent and business case approval perform different functions. Wiltshire Council’s decision addresses the proposed development under the planning system, while NHS England’s approval is required before the trust can proceed with the principal construction investment.
The trust has not announced a confirmed main contractor or final construction contract value in its latest planning update. The project has been described using different financial estimates in published materials, making it inappropriate to present any one figure as a verified current construction budget.
The November planning decision has established an important statutory milestone, allowing preparatory work to advance while the trust seeks its remaining approval. Main construction of the surgical and diagnostic facilities remains dependent on the full business case being authorised by NHS England.
