Capula

A UK Digital Services Consultancy

Capula have been an Expression 37 client since 2021. They are still one today. When the agency that built their Craft CMS website moved on, they needed a specialist to inherit it cleanly and keep it performing. That handover has since grown into a long-term technical partnership.

Craft CMS Technology & Digital Services Retained Technical Partnership

The Situation

Capula are part of the EDF group, serving clients across critical national infrastructure including the National Grid and nuclear facilities. Their corporate website is not a brochure. It manages contact and trial signup journeys, gated resources, and a vacancy board, serving an audience that takes time to convert and expects a professional experience at every step.

When the agency that built the site moved on, the surface looked fine. Underneath was a content architecture built for high volume and variety, bespoke modules managing navigation, forms, and email, and a deployment process that had never been formalised. None of that is visible to a visitor. All of it becomes your problem the moment something stops working and the person who built it is no longer there.

What We Did

We took on the codebase under a monthly retainer and became the team responsible for it. Scheduled Craft CMS upgrades, regular security and performance auditing, environment management, and a guaranteed response when something needs doing.

During routine monitoring we identified that a conflict between the cookie consent software and the spam protection had caused every contact and trial form on the site to silently stop processing submissions. No error. No alert. Nothing in the inbox to suggest anything was wrong. We caught it before Capula knew there was a problem. A separate issue causing email notification failures at unpredictable intervals was identified and resolved in the same period. Both were fixed permanently, not patched.

Alongside the retainer we have rebuilt the deployment process, delivered a campaign form for a product trial, reworked the job application section, and built a range of template and content work as the marketing team’s needs have evolved.

The Outcome

Capula have had a stable, well-run website since 2021. The platform has kept pace with the business, new features have been delivered without internal project management overhead, and two separate issues that were silently costing them leads were caught and resolved before anyone outside the technical team knew they existed.

That last point is worth sitting with if you are in a similar position. A website running on a platform no one in your business fully understands can feel fine right up until it is not. The value of a specialist who knows your site is not just what they fix. It is what they catch before you have to.

We delivered. Here is the evidence.

Expression 37 took over our website when our previous agency moved on, and have looked after it ever since. We have never had to worry about the platform. When we have needed something changed it gets done, and when something has gone wrong, such as our forms silently failing after we introduced cookie consent software, it was identified and fixed without us having to chase it. That kind of quiet reliability is exactly what we need from a technical partner.

Recognise this situation?

A complex website needs more than occasional fixes. A technical partner who stays close to the platform, knows its history, and catches problems before they reach you is worth considerably more than a series of one-off jobs. We have looked after this site since 2021 and that continuity is precisely what keeps a platform this complex running well.

Craft CMS Maintenance, Upgrade & Support Ongoing Maintenance & Support

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.

Respecting Client Confidentiality

Much of our work involves long-term support and maintenance arrangements for business-critical sites. A significant portion of that work is covered by non-disclosure agreements to protect client confidentiality, so we are unable to show every project publicly.
