Migrating an old Joomla website to a new hosting provider while also updating the CMS can be a sensible move. Older Joomla sites often suffer from security risks, poor performance and compatibility issues, especially if they are running on outdated hosting environments. However, the cost of migration and updates can vary significantly depending on several technical and business factors.
This article explains what affects the cost of migrating an old Joomla site in the UK, what is typically included, and what you should budget for.
Why Migrate and Update an Old Joomla Site?
Many legacy Joomla websites are still running on versions that are no longer supported. This can lead to:
- Security vulnerabilities
- Incompatibility with modern PHP versions
- Slow loading times
- Problems with extensions or templates
- Hosting providers refusing to support outdated setups
Moving to a new host and updating Joomla at the same time helps future-proof your website, improves performance, and reduces the risk of downtime or hacking.
Key Factors That Affect the Cost
The cost to migrate and update a Joomla site in the UK depends on several variables.
1. Joomla Version and Upgrade Path
A site running Joomla 2.5 or early 3.x usually requires more work than one already on Joomla 3.10. Major version jumps (for example, Joomla 3 to Joomla 4, 5 or 6) often involve template and extension replacements rather than simple updates.
Impact on cost:
- Minor updates: lower cost
- Major version upgrades: higher cost due to redevelopment work
2. Hosting Environment
If your current host uses outdated PHP or server configurations, extra work may be required to ensure compatibility on the new host. UK hosting providers often run newer PHP versions by default, which older Joomla sites may not support without updates.
Impact on cost:
- Modern, compatible hosting: minimal setup
- Legacy hosting to modern server: additional configuration and testing
3. Number of Extensions and Custom Code
Older Joomla sites often rely on third-party extensions that may no longer be supported. Some may need updating, replacing, or removing altogether. Custom code can also increase complexity.
Impact on cost:
- Few, well-maintained extensions: lower cost
- Many outdated or custom extensions: higher cost
4. Template and Design
If your site uses an old template that is not compatible with newer Joomla versions, you may need a new template or a partial redesign.
Impact on cost:
- Existing template compatible: minimal design work
- New template required: increased cost
5. Size and Complexity of the Website
A small brochure site with a few pages will cost less than a large Joomla site with hundreds of articles, users, or multilingual content.
Impact on cost:
- Small sites: faster migration
- Large or complex sites: more testing and labour

Extension Licences
Some premium Joomla extensions require annual renewals, typically £20–£100 per extension.
Ongoing Maintenance
After migration and update, ongoing support is strongly recommended. UK maintenance plans usually range from £250 to £750 per month.
How to Keep Costs Under Control
- Carry out a full site audit before starting
- Remove unused extensions and content
- Choose a UK host that supports Joomla well
- Plan upgrades in stages if budgets are tight
A professional Joomla specialist can often advise whether a full upgrade is cost-effective or whether a partial rebuild would be better value.
Final Thoughts
The cost to migrate an old Joomla site to a new host and update it in the UK typically ranges from a few hundred pounds to over £1,500, depending on age, complexity and compatibility.
While it may seem like a significant investment, upgrading and migrating properly can save money in the long term by improving security, performance and reliability.
