Frequently Asked Questions
How much does cloud consulting cost in the UK?
Costs vary widely depending on project scope, ranging from a few thousand pounds for a focused assessment to six or seven figures for full enterprise migrations. Most consultancies offer an initial scoping call to provide a tailored estimate.
How long does a typical cloud migration take?
Simple migrations can take a few weeks, while complex, multi-system enterprise migrations often take several months to over a year, depending on legacy system complexity and compliance requirements.
Do I need a different consultant for AWS versus Azure?
Not necessarily, but platform-specialist partners often deliver deeper optimisation than generalists. If your organisation is committed to one ecosystem, a certified specialist is usually the safer choice.
Can a cloud consultant help after migration is complete?
Yes. Most reputable firms, including several on this list, offer ongoing managed services covering monitoring, security, cost optimisation, and support well beyond the initial migration.
Is cloud consulting worth it for small businesses?
Yes, particularly for avoiding costly missteps early on. Many consultancies, such as Cloud Bridge, also offer funding support that makes professional guidance more accessible for smaller budgets.
