Craft CMS Developer & Support in Leeds

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

Karl @ Expression 37 ~ Craft CMS Developer, Leeds

A Leeds enquiry about Craft CMS support is usually one of two things: an install that's held up fine but ignored, or one that's genuinely broken with the previous developer unreachable.

Karl works with Leeds and wider Yorkshire businesses directly, every time. Craft CMS and ExpressionEngine are the only platforms Expression 37's ever worked in, since 2007. You deal with him personally.

He reads the actual install before proposing anything. Most first engagements move to an ongoing retainer once that initial job's done.

Where this typically applies:

  • Leeds businesses where downtime has a direct, measurable cost, not just an inconvenience that can wait until Monday.
  • Sites passed between account managers at an agency, none of whom ever really understood the build underneath.
  • Installs several major Craft versions behind, needing a proper plugin and Composer audit before an upgrade is safe.
  • Businesses running Stripe, Salesforce, or HubSpot through a connection nobody currently understands properly.

Common questions from Leeds clients:

Working with a remote developer, does that actually suit a Leeds business?

It suits most. Working directly with whoever's actually handling your site, rather than through an agency's account management layer, tends to be faster and more reliable, and on-site visits are rarely needed.

Can you take on a Craft build from a developer we've lost contact with?

Yes, and it's one of the more common starting points. Customised templates and unusual plugin setups get untangled properly before anything is changed, no assumptions made.

Our install's been sitting on an old Craft version for years, is that a problem?

Not an unusual one. Expect the real work to be in checking every plugin's compatibility and resolving Composer conflicts, not the core software update itself.

Is the Stripe, Salesforce, or HubSpot connection something you'll also look after?

Yes. Those integrations are typically wired straight into the templates, so they're maintained as part of the same system rather than handed off separately.

What's the actual cost structure?

A fixed price for a defined job, an audit or upgrade. A monthly retainer if it becomes ongoing. The number's agreed before anything starts either way.

What happens if something breaks and it's urgent?

Retainer clients are handled first. Without a retainer, urgent issues still generally get a fast response, but guaranteed priority is specifically what the retainer provides.

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.
