What Does Cloud Migration Actually Cost UK SMEs in 2026?
Cloud migration has moved from a "nice to have" to a business necessity for most UK small and medium-sized enterprises. But when decision-makers sit down to budget for it, they're often confronted with wildly inconsistent pricing, confusing provider tiers, and a lack of straightforward guidance tailored to businesses their size.
This guide cuts through that confusion. Whether you're running a 20-person professional services firm or a 200-seat manufacturing operation, here's what you can realistically expect to spend — and how to plan smartly.
Why Cloud Migration Costs Vary So Dramatically
The honest answer to "how much does cloud migration cost UK businesses?" is: it depends — but that answer only becomes useful when you understand what it depends on.

The primary cost drivers are:
- Volume and complexity of data — Migrating a simple file server is very different from migrating a custom ERP system with years of legacy data
- Current infrastructure — On-premise servers, hybrid environments, and ageing hardware all affect complexity
- Downtime tolerance — Zero-downtime migrations require more careful (and expensive) planning
- Compliance requirements — Regulated industries (finance, healthcare, legal) require additional security controls and audit trails
- Choice of cloud platform — Azure, Microsoft 365, AWS, and Google Workspace each have different pricing structures
- Whether you use a migration consultant — DIY is cheaper upfront but frequently more costly long-term
Cloud Migration Pricing UK: SME Cost Benchmarks for 2026
These figures reflect real-world cloud migration pricing in the UK market for SMEs. They are indicative ranges, not fixed quotes.
Small Business (10–30 users)
- Microsoft 365 migration (email, SharePoint, Teams): £1,500–£4,000 one-time
- Cloud storage/file server migration: £1,000–£3,500
- Full infrastructure migration to Azure: £5,000–£15,000
- Ongoing monthly costs post-migration: £300–£900/month
Mid-Sized Business (30–150 users)
- Microsoft 365 migration: £4,000–£12,000
- Azure migration cost (UK business, mid-tier): £15,000–£50,000
- Line-of-business application migration: £10,000–£40,000+
- Ongoing monthly cloud costs: £900–£5,000/month depending on workloads
Larger SMEs (150–250 users)
- Full cloud transformation project: £50,000–£150,000+
- Phased migrations are common at this size to manage cost and risk
- Ongoing spend: Often £5,000–£15,000/month across licensing, infrastructure, and support
These figures cover professional services and technical labour. They do not include ongoing software licensing, which is a separate and often underestimated cost.
The Hidden Costs Most SMEs Miss
The cost of migrating to cloud in the UK is rarely just the migration itself. Budget-conscious business owners are often caught out by:
1. Licensing uplift Moving to Microsoft 365 Business Premium instead of a basic plan adds roughly £10–£15 per user per month — but often unlocks significant security and productivity features worth the investment.
2. Data egress fees Cloud providers charge for moving data out of their platforms. If you're consolidating from multiple providers or need regular large exports, this adds up.
3. Training and change management Staff adoption is consistently underbudgeted. A £20,000 migration that your team ignores or misuses delivers poor ROI. Budget for structured onboarding.
4. Parallel running costs During migration, many businesses run old and new systems simultaneously. This can mean double infrastructure costs for weeks or months.
5. Remediation of poor IT hygiene Legacy systems often carry years of duplicated data, outdated permissions, and inconsistent naming conventions. Cleaning this up before migration is essential — and takes time.
Azure Migration Cost UK: Is Microsoft the Right Choice for Your Business?
For most UK SMEs already using Microsoft products, Azure and Microsoft 365 represent the most natural migration path. The Azure migration cost for UK businesses varies significantly by workload, but Microsoft's pricing calculator (available free online) can give you a working estimate.
Key considerations:
- Azure Hybrid Benefit allows businesses with existing Windows Server licences to reduce Azure VM costs significantly
- Reserved Instances (committing to 1 or 3 years) can reduce compute costs by 30–40% versus pay-as-you-go
- Microsoft's UK data centres (UK South and UK West) ensure GDPR compliance without complex data residency workarounds
At Coreitech, we recommend most London and South East SMEs start with a Microsoft 365 migration before tackling full infrastructure migration to Azure. It delivers fast wins, improves security posture, and gives your team time to adapt before more complex workloads move.
How to Plan Your Cloud Migration Budget: 5 Practical Steps
1. Conduct a proper asset inventory
Before you can price a migration, you need to know exactly what you have. Document every server, application, and dataset — including who uses it and how often.
2. Define your success metrics upfront
Cost savings? Improved uptime? Remote working capability? Having clear outcomes helps your consultant scope the right solution rather than over-engineer it.
3. Phase the migration
Attempting to move everything at once increases risk and cash flow strain. A phased approach — typically email and collaboration tools first, then file storage, then applications — is more manageable for most SMEs.
4. Separate CapEx from OpEx
Cloud migration shifts IT spend from capital expenditure (buying servers) to operational expenditure (monthly subscriptions). This has tax implications and affects how your finance team reports costs. Involve your accountant early.
5. Get multiple scoped quotes — not ballpark figures
A cloud migration consultant in London or elsewhere in the UK should provide a detailed statement of work, not a back-of-envelope estimate. Vague quotes lead to scope creep and cost overruns.
Choosing a Cloud Migration Consultant in London and the UK
Working with a managed IT provider who specialises in cloud migration — rather than a generalist IT company or a large consultancy that will hand your project to a junior team — makes a material difference to outcomes.
Look for:
- Proven Microsoft partnership status (Silver or Gold/Solutions Partner)
- Demonstrable SME experience with businesses similar to yours
- Fixed-price or milestone-based project pricing, not open-ended day rates
- Post-migration support included or clearly scoped
