Planning Permission & Change of Use
Whether you need planning permission depends on the current use class of the building you are working with. In England and Wales, dental practices fall under Class E (commercial, business and service), which covers a wide range of uses including retail, offices, and health services. In Scotland, the equivalent is Class 1A. A change of use application may be required if the existing building is in a different use class.
A change of use application will need to demonstrate:
- That the proposed use is appropriate for the area and will not cause significant amenity issues for neighbours
- That adequate access is available for patients, including those with mobility requirements
- That waste management, including clinical waste, can be handled appropriately from the site
- That any external changes to the building — new signage, extraction venting, ramp access — are acceptable within the local planning context
NVDC prepares and submits planning applications as part of our standard service, and where helpful we engage with the planning authority at pre-application stage to confirm what is required before any fees are committed.
">At Buttercup Dental in Glasgow's Broomhill Shopping Centre, the premises were already in retail use, which simplified the change of use process considerably. At Eilertsen Dental Care in Inverness — a new practice for a dentist relocating from Dingwall after 30 years — the change of use from commercial to clinical use required a straightforward application supported by a basic access and waste management statement.
Building Warrant & Building Regulations
All dental fit-outs that involve structural changes, new drainage, or changes to means of escape require approval under the relevant building regulations. Even where no structural work is proposed, most dental practices will require a building warrant or building regulations approval because the installation of dental chairs, suction systems, and medical gas involves notifiable work.
The building regulations most relevant to a new dental practice include:
- Fire safety: means of escape, emergency lighting, and fire detection — particularly relevant where the practice is on an upper floor or within a multi-occupancy building
- Accessibility (DDA compliance): all patient areas must comply with accessibility standards, including reception, waiting areas, surgeries, and accessible WC provision
- Drainage: dental practices produce clinical wastewater containing mercury amalgam — an appropriate amalgam separator is required and must be integrated into the drainage design
- Thermal performance: insulation and U-values must meet current standards, particularly relevant in conversions of older commercial buildings
- Ventilation: surgeries require mechanical ventilation to remove aerosol contamination, with standards updated following guidance issued post-2020
HTM 01-05: Decontamination in Dental Practices
HTM 01-05 is the Health Technical Memorandum that sets the standard for decontamination of dental instruments. It is now widely adopted by dental operators, their indemnity insurers, and inspection bodies as the benchmark for clinical hygiene standards, and it directly shapes the physical design of your practice.
Key design requirements under HTM 01-05 include:
The decontamination room must be physically separated from the surgeries and designed as a dedicated clean processing facility.
The room must have a clearly defined 'dirty' zone and a 'clean' zone — clearly marked to prevent cross-contamination.
Handwash-only sinks must be provided at the entrance to the decontamination room, separate from instrument cleaning sinks.
Adequate storage for sterile packs, with clear separation from unprocessed instruments, must be built into the surgery layout.
The ventilation strategy must support the decontamination process — extraction in the dirty zone and supply of fresh air in the clean zone, all balanced to provide negative pressure in the room.
Inspection Frameworks & What They Mean for Your Design
In England, dental practices must be registered with the Care Quality Commission (CQC) under the Health and Social Care Act 2008. In Scotland, Healthcare Improvement Scotland (HIS) provides the equivalent oversight framework for independent healthcare providers, including dental practices.
The aspects of the physical environment most closely assessed by inspection frameworks include: the adequacy of infection prevention and control measures embedded in the building design — decontamination room layout and instrument flow are directly assessed; the suitability of clinical areas for the procedures being carried out; the accessibility of the building for patients with mobility, sensory, or communication needs; and the adequacy of staff facilities.
NVDC designs all dental practices with these inspection frameworks in mind from the outset. Designing for compliance from day one avoids costly remedial works after practical completion and gives clients confidence that their premises will pass inspection at first registration.
Working with an Existing Building: What to Check Before You Commit
The most common issue NVDC encounters when a dentist has already agreed heads of terms on a commercial unit is that the building has a fundamental constraint that either rules out a dental practice or significantly increases the cost of fit-out.
NVDC recommends commissioning a brief technical feasibility review before heads of terms are agreed. This typically involves a site visit or a desktop appraisal to review the existing building layout, drainage provision, access, etc., and a written summary of what is potentially achievable. The fee for this is modest relative to the risk of discovering a fundamental constraint after a lease has been signed.
The most frequent problems are:
Ceiling height
Insufficient floor-to-ceiling height to accommodate the ductwork required for surgery and local decontamination room ventilation.
Drainage
Inadequate drainage capacity or drainage positioned in the wrong part of the floor plate for surgery locations.
Structural constraints
Structural layout or load-bearing walls that prevent efficient space utilisation without major and costly structural alterations.
Listed & conservation restrictions
Conservation area or listed building restrictions that prevent internal and external changes to the building layout and fabric to facilitate services and external extraction venting.
