ExpressionEngine Developer & Support in Cardiff

Long-term ExpressionEngine support, version upgrades, and specialist development for businesses that cannot afford for their website to fail.

Karl @ Expression 37 ~ ExpressionEngine Developer, Cardiff

ExpressionEngine enquiries from Cardiff businesses usually mean the site's in one of two states, ticking over unpatched, or genuinely causing problems with nobody left to call.

Karl handles it from there, on his own. He's kept Expression 37 to ExpressionEngine and Craft CMS only since founding it in 2007.

The site gets reviewed properly before anything's recommended. Depending on what Karl finds, that's a fix, an upgrade, or a retainer.

Who this tends to matter for:

Media and broadcasting organisations where downtime or a factual error carries reputational weight, not just a commercial one. Public sector bodies with accessibility and accuracy obligations that a badly maintained CMS quietly puts at risk. Organisations running content in both Welsh and English where the two versions have drifted apart because the original setup never linked them properly. And any business whose previous developer or agency is no longer contactable, leaving a site that works today but that nobody could confidently change tomorrow. Where Stripe payments or a HubSpot contact sync sit alongside the CMS, treating them as a separate problem from the site itself tends to be where things quietly break.

What the first few weeks usually involve:

Before quoting anything, Karl reviews the templates, the add-ons, and however the bilingual content is currently structured, since Cardiff handovers often come with more assumptions than documentation. Most engagements start from a specific prompt: a content workflow that's become unworkable, a security notice about an outdated add-on, or a straightforward decision that the site needs proper ownership again. From there it's either a defined project or a retainer, agreed before any work starts.

Common questions Cardiff clients tend to ask:

Does it matter that you're not based in Cardiff?

Not for the work itself. Everything from code review to deployment happens remotely, and it holds up well in practice. Cardiff is close enough that an in-person conversation is never a real obstacle when one's genuinely useful.

Can ExpressionEngine handle Welsh and English content properly, or does that need rebuilding?

It can be done properly without a rebuild in most cases. The channel and field structure supports genuinely linked bilingual content, the issue is usually that an older site was set up as two loosely connected sections rather than one coherent structure, and that's fixable.

We took this site over from a previous developer, can you make sense of it?

Yes, it's one of the most common starting points. Working out what's bespoke, what's a modified add-on, and what's simply undocumented takes a proper read of the code rather than a guess from the front end.

How far behind can an install get before it's genuinely risky?

There isn't really a threshold. Plenty of EE2 and EE3 sites still run fine. The exposure builds in the add-ons wrapped around the core, not the core itself, so age alone isn't the useful question to ask.

What does ongoing support actually cover?

Faster response when something goes wrong, someone actually checking the site periodically instead of waiting to hear about a problem, and the same developer handling it each time rather than a new face.

How is this priced?

A one-off audit or project is a fixed quote. Ongoing support runs as a monthly retainer. Either way, the cost is agreed before anything starts.

Ready to get started?

If your website is business-critical and needs a specialist who will take proper long-term ownership of it, get in touch. Karl will respond personally and give you an honest view of how we can help.

Can we help?

Most clients come to us when their site has started to feel like a risk rather than an asset. Whether the agency relationship has ended, an upgrade has been delayed, or the site has simply grown beyond what it can handle, a conversation costs nothing.

About Karl

Karl Bowers ~ ExpressionEngine & Craft CMS Specialist

Karl founded Expression 37 in 2007 and has worked exclusively with ExpressionEngine and Craft CMS ever since. He does not take on work in other platforms and does not hand work to other developers. Expression 37 is deliberately small, because the kind of support that matters to clients with business-critical sites is specific to their site, not something that scales in the conventional sense. If you work with Expression 37, you work with Karl.

Client feedback:

I cannot recommend Karl highly enough for his expertise and professionalism during our website upgrade. The transition from ExpressionEngine v2 to v7 was a significant undertaking, but Karl managed the entire process seamlessly, ensuring that every detail was addressed. The update of over 70 add-ons and 10 custom plugins was executed flawlessly, and the custom enhancements to our E-Commerce Store module have greatly improved our online shopping experience. The move to a more secure dedicated server has given us peace of mind regarding our site's performance and security. Karl’s dedication to our project was evident at every stage, and the final result is a modern, efficient website that truly represents our brand. Thank you for your hard work!"
