Choosing the right Microsoft 365 licence can be confusing.
Many Scottish businesses know they need Microsoft 365 for email, collaboration, security, and productivity, but aren't sure whether Microsoft 365 Business Premium or Microsoft 365 E5 is the better investment.
For most organisations with 10–100 employees, Microsoft 365 Business Premium delivers the best balance of productivity, security, and value. However, businesses with advanced compliance, security, governance, or regulatory requirements may benefit from Microsoft 365 E5.
In this guide, we'll compare the two options, explain the key differences, and help you determine which licence is right for your organisation.
The Short Answer
For most Scottish SMEs, charities, engineering firms, manufacturers, construction companies, and professional services organisations:
Choose Microsoft 365 Business Premium if:
- You have fewer than 300 users
- You want strong cybersecurity protection
- You need device management
- You want predictable licensing costs
- You use Microsoft 365 as your primary productivity platform
Consider Microsoft 365 E5 if:
- You operate in a heavily regulated industry
- You have advanced compliance requirements
- You need enterprise-grade analytics
- You require advanced security and investigation tools
- You have dedicated IT and security teams
For many organisations, Business Premium provides 80–90% of the functionality they actually need at a significantly lower cost.

Business Premium vs E5: Feature Comparison
| Feature | Business Premium | E5 |
| Desktop Office Apps | ✓ | ✓ |
| Exchange Online | ✓ | ✓ |
| Teams | ✓ | ✓ |
| OneDrive | ✓ | ✓ |
| SharePoint | ✓ | ✓ |
| Microsoft Intune | ✓ | ✓ |

| Advanced Threat Protection | Limited | Advanced |
| Data Loss Prevention | Basic | Advanced |
| eDiscovery | Limited | Advanced |
| Insider Risk Management | No | Yes |
| Power BI Pro | No | Yes |
| Advanced Compliance Tools | No | Yes |
The key question is not which licence has more features.
The question is:
Which licence provides the capabilities your organisation will actually use?
Cost Comparison
Microsoft licensing changes periodically, but E5 typically costs significantly more than Business Premium.
Example: 50-User Organisation
Business Premium
Approximate annual investment:
50 users × Business Premium licence
E5
Approximate annual investment:
50 users × E5 licence
The difference can easily amount to many thousands of pounds per year.
For organisations with limited compliance requirements, this additional cost may not deliver sufficient business value.
Which Licence Is Best for Scottish SMEs?
For most SMEs, Business Premium is the clear winner.
Ideal for:
- Accountancy firms
- Engineering companies
- Manufacturers
- Construction businesses
- Professional services organisations
- Charities
- Housing associations
Benefits include:
- Strong cybersecurity
- Device management
- Cloud productivity
- Lower licensing costs
- Easier administration
Most organisations in the 10–100 employee range will find Business Premium meets their requirements.
Which Licence Is Best for Charities?
Most charities benefit significantly from Business Premium.
Reasons include:
- Cost efficiency
- Strong security features
- Microsoft 365 productivity tools
- Device management capabilities
- Remote working support
Charities often need practical security rather than enterprise-level compliance functionality.
Business Premium typically provides the best balance of protection and affordability.
Which Licence Is Best for Law Firms?
Law firms require careful consideration.
Business Premium may be sufficient for many practices.
However, E5 may be appropriate where:
- Highly sensitive client data is processed
- Advanced compliance controls are required
- Data retention requirements are extensive
- Security investigations are common
The decision should be based on regulatory obligations and risk profile.
Which Licence Is Best for Manufacturing and Engineering Companies?
Most manufacturing and engineering firms benefit from Business Premium.
Common requirements include:
- Secure remote access
- Device management
- Cybersecurity controls
- Collaboration tools
- File sharing
Business Premium generally delivers all of these capabilities without the cost of E5.
Five Questions to Ask Before Choosing
1. How Many Users Do We Have?
Business Premium supports up to 300 users.
2. Do We Have Regulatory Compliance Requirements?
Organisations with advanced compliance obligations may benefit from E5.
3. Do We Have Dedicated Security Personnel?
Many E5 features require specialist expertise to configure and manage effectively.
