A Standard Operating Procedure (SOP) is a documented set of step-by-step instructions that explains how to perform a task correctly and consistently. SOPs are used by businesses of every size and sector to standardise working methods, reduce errors, support staff training and demonstrate compliance.
This guide explains what an SOP is, why businesses use them, what they should include, how to write one and how to keep them current. Read our complete guide on Standard Operating Procedures for UK Businesses to understand the full scope of SOP development and implementation.
What Is a Standard Operating Procedure?
A Standard Operating Procedure (SOP) is a formal document that describes the approved method for completing a specific task or process within an organisation. It provides clear, repeatable instructions that employees can follow consistently, regardless of experience level or shift.
SOPs are distinct from policies and general guidance. Read our guide on SOP vs Policy vs Procedure to understand how these documents work together within your organisation.
Why Businesses Use SOPs
Effective SOPs help organisations:
- Improve consistency across teams and locations
- Reduce costly mistakes and rework
- Meet ISO, regulatory and customer requirements
- Simplify employee onboarding and training
- Improve health and safety compliance
- Maintain consistent quality
- Support audits and inspections
- Protect institutional knowledge when staff change
Read our complete guide on ISO 9001 Standard Operating Procedures to understand how SOPs connect to quality management systems and certification requirements.
What Should an SOP Include?
A professional SOP typically contains:
- Title and document reference
- Purpose and objectives
- Scope — what is and is not covered
- Roles and responsibilities
- Definitions of key terms
- Equipment or materials required
- Step-by-step procedure
- Safety and compliance requirements
- Records and documentation
- Review schedule
- Revision history and approval details
SOP vs Policy vs Procedure
These terms are often used interchangeably but have distinct meanings. A policy sets the organisational intent or rule. A procedure explains the general process. An SOP provides the specific, step-by-step instructions for completing a task. Read our guide on SOP vs Policy vs Procedure for a full comparison.

How to Write an SOP in 7 Steps
1. Define the Purpose
Explain why the procedure exists and what it aims to achieve.
2. Identify the Scope
Clearly state which departments, roles or processes are covered.
3. Assign Responsibilities
List who is responsible for carrying out each step and who is responsible for reviewing the procedure.
4. Write the Procedure
Break the process into simple, numbered steps. Use clear language and avoid jargon where possible.
5. Include Safety or Compliance Requirements
If the task involves legal, health and safety or quality requirements, include them within the procedure. Read our guide on Health & Safety SOPs every UK business should have to understand how safety requirements connect to your SOP framework. Our Risk Assessment SOP Template provides a structured framework for identifying and controlling workplace hazards.
6. Review and Test
Ask someone unfamiliar with the process to follow the SOP. Their feedback can highlight areas that need clarification. Read our complete guide on Internal Audit Procedures to understand how auditing connects to SOP review and continuous improvement.
7. Keep It Updated
Review SOPs regularly and update them whenever processes, equipment or regulations change. Our Document Control SOP Template ensures your SOPs are version-controlled, approved and retained correctly throughout their lifecycle.
SOP Implementation
Writing an SOP is only the first step. Effective implementation requires communicating the procedure to relevant employees, providing training where needed, embedding the SOP into induction processes and scheduling regular reviews. Read our guide on employee onboarding SOPs to understand how to embed procedures into staff induction.
Document Control for SOPs
All SOPs should be subject to document control — version-numbered, approved before issue, stored in a controlled location and reviewed on a defined schedule. Read our complete guide on Document Control Procedures to understand how to manage SOP versions and approvals correctly.
Common Mistakes to Avoid
- Using vague or ambiguous instructions
- Making procedures unnecessarily long
- Leaving out safety or compliance information
- Failing to review documents regularly
- Not involving employees in the review process
- Storing SOPs in uncontrolled locations
