Magento Agency UK: Senior Magento and Adobe Commerce Developers Who Stay After Launch

Magento is ecommerce software you install on your own server to run an online shop. It handles your catalogue, prices, checkout, customer accounts and orders. It is open source, so developers can change almost anything about it. That flexibility is why larger and B2B merchants pick it, and also why it needs a proper development team behind it.

Mostly, yes. Adobe bought Magento in 2018. The free version is now called Magento Open Source and the paid, licensed version is called Adobe Commerce. They share the same core code and version numbers. Adobe Commerce adds features such as B2B tools, advanced promotions and Adobe’s own support, plus an optional Adobe-run cloud hosting setup.

Yes, plenty of UK merchants do, especially B2B wholesalers, manufacturers and retailers with big or complicated catalogues. Adobe is still shipping new versions: 2.4.9 came out on 12 May 2026, with standard support running to May 2029. What has changed is that small, simple shops have mostly moved to hosted platforms like Shopify.

Magento 1 is, and has been for years. If you are still on it, you are running software with no security fixes. Magento 2 is not end of life. Adobe publishes support dates for every 2.4.x release line, and each one gets three years of standard support from its release. Older 2.4 lines are running out, so check yours.

Magento Open Source is still free to download and use. Running it is not free, though. You pay for hosting, extensions, and the developers who keep it patched, upgraded and working. Adobe Commerce, the paid edition, needs a licence from Adobe on top. So the software is free, but a well-run Magento store never is.

A Magento developer builds and maintains Magento stores. Day to day that means applying security patches, upgrading versions, writing custom modules, fixing broken extensions, connecting the store to other systems like an ERP, and making pages load faster. A senior Magento developer also decides what not to build, which saves you more than the code they write.

It needs real engineering to run well. You own the hosting, the security patches and the upgrades. Extensions from different vendors can clash. The standard front end is slow unless you rebuild it, often with Hyvä. And good Magento developers are harder to find than Shopify ones. None of that is fatal, but it is why agency choice matters so much.

For the people running the shop day to day, the admin panel is learnable in a few days: products, orders, promotions and customers. For developers it is one of the harder ecommerce platforms. It has a large, layered codebase and its own way of doing things. That learning curve is why a generalist PHP developer often struggles on a Magento 2 store.

On Adobe’s own release list, the newest release line is 2.4.9, released on 12 May 2026, with standard support until 31 May 2029. The 2.4.8 line is still supported until 31 May 2028 and got its latest security patch the same day. If you are on 2.4.6 or older, your standard support has already ended.

Start with an audit, not the upgrade button. List every extension and custom module, check each one works with the target version, and confirm your server’s PHP and database versions are supported. Then upgrade on a copy of the site, test checkout, payments and integrations properly, and only then deploy to live, ideally at a quiet trading hour.

You stop getting security fixes, so every new vulnerability stays open on your store. Payment providers and insurers take that seriously. If you run Adobe Commerce on Adobe’s cloud, it is stricter: from 1 June 2027 Adobe says it will stop maintaining cloud environments on unsupported versions and may suspend traffic, which takes the store offline.

Hyvä is a replacement front end, or theme, for Magento 2. The theme is the part shoppers see: pages, menus, product listings. Magento’s original theme is heavy and slow. Hyvä strips it back using modern tools called Tailwind CSS and Alpine.js, so pages ship far less code to the browser and load much faster, especially on phones.

Yes. Hyvä made its theme open source and free, available on GitHub under the OSL licence. Some Hyvä products are still paid, such as Hyvä Checkout, Hyvä UI and Hyvä Enterprise, which adds support for Adobe Commerce-only features. The real cost of Hyvä is the build work, because every extension on your store needs a Hyvä-compatible version.

It depends mostly on your extensions. A store with a tidy set of popular extensions that already have Hyvä compatibility modules moves quickly. A store with years of custom front-end code and niche extensions takes longer, because each one needs rebuilding or replacing. We give you a real timeline after the health check, once we have counted what is there.

An extension, also called a module, is an add-on that gives Magento a new feature, like a payment method or a product filter. Most stores collect dozens over the years, from different vendors, some abandoned. They can conflict with each other, slow pages down and block upgrades. Removing the ones you no longer need is often the cheapest speed and security win.

Magento needs more than cheap shared hosting. Look for a PHP and database version supported by your exact Magento release, OpenSearch for catalogue search, Redis for caching, Varnish for full-page caching, a CDN, a separate staging site, and daily backups you have actually tested restoring. A UK or nearby European data centre helps page speed for UK shoppers.

No. We are not a hosting company and we do not resell servers. We work with your existing host, or help you choose a specialist Magento host if yours is struggling. Keeping hosting separate from development means you are never locked to one supplier, and it gives you an honest second opinion when the host and the code blame each other.

The best Magento hosting is the one set up for Magento specifically, with a support team that knows the platform. Generic web hosts often struggle with its memory, caching and search needs. Ask any host whether they support your Magento version, offer staging and Varnish, and will help during an upgrade. Those answers tell you more than a price list.

From a Magento agency that offers an ongoing support retainer, not just build projects. Good Magento support covers security patching, monitoring, bug fixes, small improvements and a named team who already know your store. We run Magento support and maintenance for UK merchants remotely, with the same senior developers on your account every month.

The ones UK merchants usually run alongside it: accounting and ERP systems such as Sage, Microsoft Dynamics 365 Business Central and NetSuite, order and inventory tools like Brightpearl and Linnworks, Akeneo for product data, Klaviyo for email, and payment gateways. If a system has an API, a Magento integration is normally possible. We confirm yours during the health check.

Yes. We build custom AI agents that connect to Magento, for example answering order status questions from live order data, helping staff find products, or drafting product descriptions from your own attributes. They are built for your store and you own them. Our UK AI agents page covers how we approach that work in more detail.

There are many, from large Adobe partners to small specialists. Names that show up often in UK searches include Envisage Digital, Develo, PushON, Scandiweb, Chilli Apple, magic42 and Deploy eCommerce. We list them further up this page with a short note on each. The right one depends on whether you need a big build or senior, ongoing support.

The best Magento agency for you is one that has kept stores like yours running for years, not just launched them. Ask to speak to a client they have supported for more than two years. Ask who applies security patches and how fast. Ask how they decide whether to add an extension or write custom code. Good agencies answer those plainly.

It depends on the shape of the work. A one-off health check is small. An ongoing support retainer depends on how many hours of senior time you need each month. An upgrade or Hyvä rebuild depends on your extensions and custom code. We scope and quote after a health check rather than guessing, because two stores on the same version can differ hugely.

A good freelancer is fine for small, well-defined jobs. The risk is cover: when they are ill, on holiday or busy with another client, nobody else knows your store, and Magento problems rarely wait. An agency gives you more than one person who knows your codebase, plus code review. For a store that earns real money, that cover matters.

We do not claim Adobe partner status. We are an independent Magento and Adobe Commerce agency: a team of senior ecommerce engineers who support, upgrade and integrate Magento Open Source and Adobe Commerce stores. If a formal Adobe partnership is a requirement for your procurement, we will say so upfront rather than waste your time. Many merchants care more about who actually does the work.

Yes. We work with merchants across the UK, from London and the South East to Manchester, Birmingham, Leeds and Scotland. Magento support, upgrades and integrations are done remotely, with regular video calls and a shared ticket board. You get the same senior Magento developers wherever you are, and nobody has to visit your office to patch a server.

Yes, and it is most of what we do. We start with a health check: code review, extension audit, version and hosting check, and a list of risks in priority order. Then we take over support once access and documentation are handed across. If the previous agency has gone quiet, we can usually recover access through your hosting account.

Shopify is usually better if you want less technical responsibility and your catalogue and pricing are fairly standard. Magento is usually better if you have complex B2B pricing, very large or configurable catalogues, several stores on one back end, or custom logic you cannot give up. We build on both, so we have no reason to push you either way.

Move if Magento’s running costs and upgrade work are outgrowing what the flexibility earns you, and your needs fit Shopify or Shopify Plus. Stay if your store depends on complex rules Shopify cannot handle without heavy workarounds. A health check answers this properly. Sometimes the right answer is to fix Magento first and decide later, with better information.

It depends on catalogue size, how much custom Magento functionality has to be rebuilt as Shopify apps, how many integrations need rewiring, and whether you want a new design. A data-only move is a very different job from a full replatform with an ERP connection. We scope it after an audit and explain the trade-offs before quoting.

You should not, if the migration is done carefully. That means mapping every old URL to its new one with permanent redirects, keeping page titles and content that rank, and checking nothing important disappears. Most ranking losses after a migration come from missed redirects. We treat the redirect map as a core deliverable, not an afterthought.
