NHS Safety Alert: Why GP Surgeries Should Review Their Patient Weighing Scales

Accurate patient weight is not a minor admin detail. It is a clinical safety requirement.

NHSScotland Assure’s Safety Action Notice SAN2603, issued in June 2026, has highlighted serious risks around inappropriate patient weighing scales in GP surgeries and primary care settings. For practices, clinics, care homes and community healthcare teams, the message is clear: patient weighing equipment should be reviewed, unsuitable scales removed from clinical use, and compliant medical weighing devices put in place.

The notice follows a SCOTSS survey that found widespread non-compliance across primary care settings. According to the published alert, 82% of GP practices surveyed were non-compliant, only 18% were fully compliant with legal and NHS standards, 43% were using scales not legal for clinical use, and 55% of devices failed to meet NHS Class III accuracy requirements.

For any setting where weight is used for monitoring, diagnosis, treatment, medication dosing, fluid management or nutritional assessment, domestic bathroom scales and unclassified devices are not appropriate. Medical weighing needs equipment that is suitable for the patient group, properly verified, traceable and maintained.

What SAN2603 says GP surgeries should do

The safety action notice asks healthcare organisations to identify and review all patient weighing equipment in primary care settings, including GP practices and community services. It also calls for non-compliant or unsuitable devices to be removed from clinical use, including domestic and bathroom scales.

In practical terms, this means every practice should be asking the following questions:

• Do we know exactly which patient weighing scales are in use across all consulting rooms, treatment rooms and community bags?
• Are all clinical weighing scales Class III or higher where weight is used for monitoring, diagnosis or treatment?
• Are any domestic, bathroom, Class IIII or unclassified scales still being used for clinical weighing?
• Are scales suitable for the patient group, including babies, children, wheelchair users and bariatric patients?
• Do we have documented calibration, verification, servicing and maintenance records?
• Are accuracy checks completed using appropriate traceable test weights rather than staff body weight or unverified loads?
• Do procurement processes prevent unsuitable scales being purchased in future?

Why Class III medical scales matter

Weight is used throughout clinical care. It can influence medicine dosing, diagnosis, nutritional assessment, fluid management, long-term condition monitoring and clinical risk assessment. An inaccurate weight reading can therefore lead to inappropriate treatment decisions, including under-dosing or over-dosing medicines.

Class III medical weighing devices are designed for clinical weighing and are subject to tighter accuracy expectations than lower-class or domestic devices. The safety notice explains that a typical Class III device may display weight in 0.1 kg to 0.2 kg increments with relatively small permitted error. By contrast, a Class IIII device may display in 1 kg increments and permit substantially greater deviation. For repeat measurements, dose calculations and paediatric monitoring, that difference can be clinically significant.

The key point for practices is simple: the right scale depends on the clinical use case. A stand-on scale may be suitable for routine adult weighing, but it does not solve every patient need. Babies, children, wheelchair users, patients with reduced mobility and bariatric patients may require different scale designs, capacities and graduations.

How to audit your surgery’s weighing equipment

A simple equipment audit is a sensible first step for GP practices, clinics and community teams. Use this checklist as a starting point and align it with your local governance, procurement and medical physics requirements.

1. List every scale in use. Include consulting rooms, treatment rooms, reception areas, community kits, baby clinics and storage cupboards.
2. Record the manufacturer, model, serial number and location. This helps build a traceable asset list.
3. Check the approval class and intended use. Clinical weighing should use appropriate Class III or higher medical weighing equipment where required.
4. Remove unsuitable scales from clinical use. Domestic, bathroom, unclassified or inappropriate devices should not be used for clinical patient weighing.
5. Match equipment to patient groups. Review whether you need flat scales, column scales, baby scales, chair scales, wheelchair/platform scales or bariatric scales.
6. Review calibration and verification records. Checks should use certified, traceable test weights and be properly documented.
7. Update procurement controls. Make sure future purchases specify medical use, approval class, capacity, graduation, cleaning needs and servicing expectations.

Important: this article is intended as general purchasing and equipment guidance. Always follow your organisation’s local policies, clinical engineering guidance, medical physics advice and manufacturer instructions.

Which scale type should a GP practice consider?

Most practices will need more than one type of scale to cover all patient groups safely. A basic approach is to map scale type against the patients and workflows you actually support.

Clinical need	Scale type to consider	Example Seca option
Routine adult patient weighing	Class III flat scale or column scale	Seca 875 or Seca 878
Weight, height and BMI in one station	Column scale with measuring rod	Seca 704
Mobile clinics or multi-room use	Lightweight portable flat scale	Seca 877
Patients who cannot stand safely	Chair scale	Seca 955
Wheelchair users or higher-capacity needs	Platform or wheelchair scale	Seca 675
Babies, toddlers and children	Paediatric baby / child scale with suitable graduation	Seca 384 or Seca 385

Procurement questions before replacing clinical scales

When replacing patient weighing equipment, do not buy on price alone. A cheaper scale that is not appropriate for clinical use can create governance, safety and operational risk.

• Approval class: is the scale Class III or higher where clinical weighing requires it?
• Intended use: is it clearly suitable for medical patient weighing rather than personal or domestic use?
• Patient group: does it suit adults, infants, seated patients, wheelchair users or bariatric patients?
• Capacity and graduation: are the maximum capacity and scale division appropriate for the clinical application?
• Hygiene: can the scale be cleaned effectively in the clinical environment?
• Mobility: will the scale stay in one room, move between rooms, or travel with community teams?
• Servicing and calibration: can the practice maintain proper traceability and documented checks?
• Accessories: are carry cases, ramps, measuring rods, power adapters or printer / EMR options needed?

Frequently asked questions

+ What scales should GP surgeries use for clinical weighing?

Where weight is used for monitoring, diagnosis or treatment, practices should use patient weighing equipment that is suitable for medical use and meets the relevant Class III or higher requirements. Equipment should also be appropriate for the patient group and maintained with documented calibration or verification arrangements.

+ Can GP surgeries use bathroom scales for patients?

No. The safety action notice specifically highlights domestic and bathroom scales as unsuitable for clinical patient weighing. If a patient’s weight informs diagnosis, treatment, monitoring or medication dosing, a compliant medical weighing device should be used.

+ What does Class III mean on medical weighing scales?

Class III refers to an accuracy class used for medical weighing instruments. For healthcare settings, Class III medical scales provide a higher level of measurement reliability than lower-class or unclassified scales and are the minimum standard referred to in NHS patient weighing requirements for clinical use.

+ How often should medical scales be calibrated?

Follow the manufacturer’s guidance, your organisation’s local policy, and any clinical engineering or medical physics requirements. The key is that checks should be documented, traceable and carried out using appropriate certified test weights rather than staff body weight or unverified loads.

+ Which Seca scale is best for a GP surgery?

For routine adult weighing, options such as the Seca 875, Seca 877 or Seca 878 may be suitable depending on your workflow. Practices may also need a Seca 384 or 385 for paediatric weighing, a Seca 955 chair scale for seated patients, and a Seca 675 platform scale for wheelchair or higher-capacity weighing.
