How to Choose a Magento Agency in London in 2026
The platform, upgrade and team questions to ask a Magento agency before you sign.
Key takeaways
- 01Decide first whether you need Magento Open Source or Adobe Commerce, because licensing and support differ.
- 02Check the support dates of your Magento version before you plan an upgrade.
- 03Ask how a takeover of an existing store works, including documentation and staging access.
- 04Confirm the working-hours overlap with your team, not only the agency's office location.
Start with the platform decision
Magento Open Source and Adobe Commerce share a codebase, but they differ in licensing, support and some features. Ask a prospective agency which edition they recommend for your size and why. A good answer names the trade-offs and does not push one edition by default.
Check the version and the support dates
Every Magento release has a support window. Adobe publishes its lifecycle policy, and staying on an unsupported version exposes a store to security risk. Before you talk to an agency, check your current version and the end-of-support date. Our Magento 2 upgrade guide explains the checks in more detail.
Questions to ask a London Magento agency
- How do you handle a takeover? Ask for a code and environment audit, the documentation you will get, and who has access to staging and production.
- Who does the work? Confirm which team builds, tests and supports the store, and where they are based.
- What are your working hours? For London and other UK brands, the useful question is the overlap with your working day. Ask for the exact hours of overlap in writing.
- How do you test upgrades? Look for a staging environment, a regression checklist and a rollback plan.
- What is included after launch? Patching, monitoring and an agreed response process should be in the written scope.
Red flags
- A proposal that gives no version, no support dates and no plan for extensions.
- No access to the code repository or the staging site during a takeover.
- Claims of certifications or partner status that you cannot verify on the vendor's site.
What to put in the brief
Share your current version, your top ten revenue pages, the list of extensions, your hosting setup and any integrations (ERP, payments, shipping). A specific brief gets a more accurate fixed quote.

Frequently asked questions
Should a London brand use a London agency? Not necessarily. Choose on platform experience, process and working-hours overlap. Location matters less than whether the team can answer questions during your day.
