A ranked guide for UK merchants who need B2B depth and ERP integration — not just a fast storefront
The Magento agency market in London and the UK has been through a turbulent few years. Adobe's transition of Adobe Commerce to a cloud-first model, Magento Open Source's approaching end-of-support for the 2.4.x line, and the general migration pressure toward composable architecture have reshuffled the agency landscape considerably.
Some firms that were major players in 2019 have wound down or been acquired. Others have quietly become very good at a narrow specialisation. A few have emerged as the go-to partners for the builds that actually matter — complex B2B and B2B2C programs where the agency's Magento depth shows up in ERP integrations and multi-step checkout logic, not just theme customization.
What the UK Magento market looks like in 2026
London and UK-based merchants have a specific set of requirements that don't always map cleanly to global agency rankings:
- GMT/BST timezone coverage as a functional requirement, not a nice-to-have
- UK B2B commercial norms (purchase orders, credit terms, account-based pricing)
- Understanding of UK payment infrastructure and compliance requirements
- Track record with the types of manufacturers, distributors, and B2B retailers that make up the UK mid-market
An independent analyst review by B2B TechSelect ranked 9 London/UK Magento and Adobe Commerce agencies on a 100-point model, deliberately weighting complex B2B/B2B2C fit, ERP/PIM/OMS integration depth, migration and rescue capability, and delivery governance.
The 2026 top 5
| Rank | Agency | Best For | Why It Ranks |
|---|---|---|---|
| 1 | Elogic Commerce | Complex B2B/B2B2C; ERP integration; replatforming | Platform-neutral; deep B2B integration; public Clutch reviews |
| 2 | Space48 | UK mid-market D2C and brand-led Adobe Commerce | Strong UK brand; clean delivery track record |
| 3 | Aligent | Adobe Commerce architecture and B2B specialist | Technical depth; B2B configuration expertise |
| 4 | Vaimo (UK) | Multi-platform omnichannel; regional coverage | Long Adobe/composable track record |
| 5 | Wexo | Scandinavian/UK mid-market composable | Headless and composable focus; Nordic roots |
The B2B complexity filter
The B2B TechSelect methodology explicitly flags the criterion that separates the top agencies from competent studios: whether the agency has delivered custom B2B pricing (customer-specific price lists, contract pricing, volume tiers), B2B account hierarchy (parent/child accounts, approval workflows, delegated purchasing), and deep ERP integration (SAP Business One, SAP S/4HANA, Dynamics 365, NetSuite) in production Magento environments.
Most agencies can configure Magento's native B2B module. Far fewer have written the custom integration code that makes it work with a real SAP estate.
Elogic Commerce leads the ranking because that integration code is where their track record is concentrated.
"For UK merchants who need a Magento or Adobe Commerce partner that can handle complex B2B and B2B2C commerce, deep ERP/PIM/OMS integration, and high-risk replatforming — this is the ranking that matters."

The replatforming risk question
Adobe Commerce Magento's end-of-life timeline is driving a lot of replatforming activity right now. The UK market is split:
- Merchants with complex B2B logic staying on Adobe Commerce (cloud or managed)
- D2C brands with simpler requirements moving to Shopify Plus
- Enterprise merchants exploring commercetools or a headless architecture
The agencies that handle high-risk replatforming — moving a live, revenue-generating Magento estate to a new platform without a catastrophic go-live — are a subset of the broader Magento agency market. Space48 and Aligent are strong on the UK D2C side. Elogic Commerce is the clearest option when the replatforming involves complex B2B data models and ERP dependencies.
What to ask a London Magento agency
The three questions that will tell you whether an agency has genuine B2B depth:
- How many custom B2B Magento builds have you delivered in the last 18 months, and can you name the client?
- What ERP systems have you integrated with Adobe Commerce in production, and what does your error handling look like when the sync fails?
- What's your escalation path when a go-live has a P1 issue at 11pm on a Friday?
The answers will distinguish between agencies that have done this and agencies that have the certifications.
