Why Choose Interjar as Your Magento Development Company
Interjar is a specialist Magento development company - it's all we do. We work exclusively with Magento 2, Adobe Commerce, and the Hyvä frontend, so every developer on our team has deep, focused expertise rather than surface-level knowledge across multiple platforms.
Our team holds Adobe Certified Professional and Adobe Commerce Developer credentials, and as an Adobe Silver Solution Partner we have direct access to Adobe's engineering team for complex platform issues. We have delivered Magento projects across retail, multi-channel and enterprise commerce for brands including Sosandar, Joanie Clothing, Dinny Hall, and Tieroom.
When you hire a Magento developer from Interjar, you get direct access to the senior developer assigned to your project. Every hour is billed transparently to the minute at £100/hour.
UK Magento Developers, a Certified Magento Agency
Our UK Magento developers work remotely with clients in London, Manchester, Birmingham, Leeds, Bristol, Edinburgh and beyond, from our Chester base. Every project is delivered by a team of senior developers, with day-to-day communication going direct to the developers writing your code and an account manager handling commercial matters in the background. Time is billed in one minute increments and you only pay for code that ships.
Interjar has built its reputation as a specialist Magento company, and the only platform we work on. As an Adobe Silver Solution Partner and certified Magento agency, our Magento specialists hold current Adobe Commerce Developer credentials and have delivered work for stores across retail, distribution and multi-store operations. Whether you are looking for a Magento developer company for a one-off project or an ongoing Magento partner, every engagement is led by senior, certified Magento developers, never juniors and never offshored.

Why Choose Interjar for Development?
Magento Developers UK: A Senior, Certified Team
If you are looking for Magento developers in the UK rather than offshore contractors, Interjar's team is built for you. Every Magento developer on the team is UK-employed, Adobe Commerce certified, and works exclusively on Magento and Adobe Commerce, no rotations onto WordPress or generic PHP. That platform focus is how senior Magento developers stay genuinely current rather than drifting into shallow familiarity with the platform.
We work with retail brands in London, manufacturers in the Midlands, distributors in Manchester and Leeds, and trade operators across Scotland and Northern Ireland. Our certified Magento developers cover Adobe Commerce, Magento Open Source, Hyvä themes, headless storefronts, ERP integrations, and complex multi-store operations. Whether you need ad-hoc Magento developers for an overflow project or a long-term Magento partner, the same senior people stay on your account.

Magento Development FAQs
-
How long does a typical Magento project take?
It depends on scope. A custom integration or module might take 2-4 weeks, while a full site build or major migration typically takes 2-4 months. We'll give you a realistic timeline upfront after scoping your requirements.
-
Can you work with our existing Magento store?
Yes. Most of our development work involves extending and improving existing Magento stores, adding new features, building custom integrations, fixing performance issues, and migrating from older versions.
-
Do you build custom Magento extensions?
We do. From bespoke checkout flows to ERP integrations and custom order management, we build extensions tailored to your business requirements rather than forcing you into off-the-shelf solutions that don't quite fit.
-
How do you ensure quality during development?
Every project goes through code review, automated testing, and staging environment validation before anything touches your live site. We use GitLab CI/CD pipelines for consistent, zero-downtime deployments.
-
Can you integrate Magento with our existing systems?
Absolutely. We regularly integrate Magento with ERPs, CRMs, payment gateways, shipping providers, and marketing platforms. Our Advanced Commerce integration framework handles complex multi-system orchestration.
-
What happens after the project launches?
Many of our development clients transition to a monthly retainer for continued maintenance, monitoring and iterative improvements. For ongoing maintenance see our Magento support page; for major version moves see Magento upgrades.
-
How do I choose a Magento development company?
Look for Adobe partnership status (we're a Silver Solution Partner), verified Magento 2 expertise with Adobe-certified developers, case studies with measurable results, UK-based teams rather than offshore, and direct developer access rather than account-managed communication.
-
Can I hire a Magento developer on a project basis?
Yes. We offer both project-based engagements for defined scopes of work and flexible retainer arrangements for ongoing development. All work is billed at £100/hour to the minute, with no minimum commitment and rolling 30-day contracts.
-
How much do Magento developers in the UK charge?
Our developers work at a flat £100 per hour. We bill in one minute increments and there are no tiered packages or retainers required to start.
-
Are your Magento developers certified?
Yes. Interjar is an Adobe Silver Solution Partner and our senior developers hold Adobe Commerce certifications. This means we receive direct engineering support from Adobe and early access to platform updates.
-
Do you work with businesses outside Chester?
Yes. We are based in Chester but the majority of our Magento development work is delivered remotely for clients across the UK, Ireland and mainland Europe.
-
Can I hire a single Magento developer rather than a full team?
We assign a team of senior developers to every project, with day-to-day communication going direct to the developers writing your code. An account manager handles commercial matters in the background.
