Colour-Coded Scrub Systems in Healthcare: Implementation Guide for NHS Trusts

NHS colour-coded scrub programmes have transformed clinical workforce identification across UK healthcare settings, creating a visual communication system that allows patients, families, and colleagues to identify staff roles at a glance. Since NHS England’s 2019 national uniform policy recommendations acknowledged the value of standardised colour programmes, NHS Trusts across England have been implementing or refining role-based colour-coded scrub systems — with varying degrees of standardisation, complexity, and procurement sophistication. This guide provides practical implementation guidance for Trust procurement and workforce teams commissioning or upgrading a colour-coded scrub programme.

The Case for Standardisation Within Your Trust

Role-based colour coding in clinical workwear serves three primary functions: patient safety (patients can identify who is treating them, reducing miscommunication risk); infection prevention (clear differentiation between clinical zones and roles supports restriction of specific garments to specific areas); and professional identity (well-designed colour programmes support staff pride and belonging within clinical teams). However, colour programmes only deliver these benefits when they are consistently applied — when every staff member in a given role wears the designated colour, when colour designations are communicated clearly to patients, and when procurement ensures supply consistency across the entirety of the programme’s lifespan.

Designing Your Colour-to-Role Mapping

Most NHS Trust colour programmes use between 6 and 12 colour designations covering the primary clinical grades: registered nurses, healthcare assistants, physiotherapists, radiographers, operating theatre staff, midwives, ward-based doctors, specialist practitioners, and administrative clinical staff. The NHS Employers guidance suggests avoiding colours that are too visually similar (which defeats identification purposes), selecting from a colour palette that launders quickly and reliably, and documenting the role-colour mapping clearly in both internal staff policy and patient-facing communications (posters, ward information leaflets, website). Common pitfalls include selecting colours that appear markedly different between suppliers (causing mixed-appearance teams when restocking from a different supplier), and underestimating the number of size variants required across a full staff demographic.

Procurement Considerations for NHS Colour Programmes

For NHS procurement teams commissioning a colour programme, the critical specification requirements are: minimum 40 colour options available from a single supplier; dye lot consistency across all orders placed within the procurement framework contract period (typically 3-5 years); full size range from XXS to 4XL inclusive for all style-colour combinations; garment antimicrobial performance meeting the infection control requirements of thermal disinfection at 60°C minimum wash temperature; and documentation suitable for NHS Supply Chain procurement approval processes including OEKO-TEX certification and ISO 13485-aligned manufacturing QMS. Cambay Industries provides all of these capabilities, with NHS-compatible documentation packages available for Trust procurement teams.

Rollout Planning and Change Management

Successfully implementing a colour-coded scrub programme across a large NHS Trust (500+ clinical staff) requires a phased rollout plan, a clear communications strategy for both staff and patients, an accurate size profiling exercise to determine the quantity and split by size for each colour grade, a robust stock management system to ensure reorder triggers are met before colour stock runs out (mixed colours within a grade are the most common programme failure mode), and a defined governance process for managing exceptions (agency staff, visiting specialists, bank workers).
