We build WordPress architectures that are fast, fortress-secure, and built to scale — then hand them to you to deliver as your own. No traces. No compromise. No client ever knowing we exist.
Six pillars that make Zest the development team agencies rely on — project after project, client after client.
We've been building enterprise WordPress since before page builders existed. Our code is clean, documented, and maintainable by any developer your client hires down the line.
Every build is QA'd across multiple screen sizes and browsers before handoff. No exceptions, no shortcuts — your client gets a product that works everywhere.
We assess your brief in depth before quoting. The number we give is the number you invoice. No surprise additions mid-project, no awkward client conversations.
From simple business sites to complex WooCommerce ecosystems — our team has the depth to handle every layer of your client's project without subcontracting out.
One point of contact. Always responsive. Daily or weekly updates depending on your preference. Smooth handoffs, clear documentation, no dropped balls.
We never display NDA projects publicly, never share client information, and never contact your clients directly. Your sensitive data stays completely locked.
Six specialised capabilities that let your agency say yes to any client requirement — without building an in-house team to deliver it.
Decoupled CMS architecture using React or Next.js frontend — delivering blazing performance scores while keeping the editorial experience your clients love.
From product catalog architecture to custom checkout flows and subscription logic — we build WooCommerce stores that convert and scale without technical debt.
We connect WordPress seamlessly to CRMs, ERPs, marketing stacks, payment gateways, and custom business logic — mapping complex ecosystems and building the bridges.
Managing multiple brands or regions under one CMS? We architect WordPress multisite environments with role-based access, shared assets, and clean separation between properties.
Structured content models, custom post types, and ACF setups that give your clients a powerful, flexible editing experience without touching a line of code.
Custom community platforms — memberships, social networking, forums, and user profiles — all integrated and performance-optimized for engaged audiences.
Our white-label maintenance model means your agency earns recurring revenue without carrying the operational cost of a support team.
Regular core, plugin, and theme updates. Security scans. Uptime monitoring. Monthly optimization reviews. All managed silently, all reported under your brand.
Server-level WAF configuration. Database prefix hardening. Malware removal. SSL configuration. Two-factor authentication. Real-time threat monitoring via Wordfence.
Caching architecture (Redis, LiteSpeed), image delivery via WebP and AVIF, script minification, CDN configuration, and database cleanup — turning slow sites into 90+ scoring assets.
Broken layout? Plugin conflict? Hacked site? We diagnose and resolve within 24 hours for retainer partners — no escalation required, no delays.
Before any WordPress site leaves our hands, it goes through a rigorous pre-launch review. We don't just build websites — we build secure digital assets your agency can stand behind.
Three flexible models that adapt to your agency's project volume, client roster, and preferred working rhythm.
A named WordPress developer integrated into your agency team — same person, same standards, same NDA — for long-term collaboration on complex or ongoing client work.
A block of development hours per month, flexible across multiple clients and projects. Ideal for agencies with consistent but variable development demand.
Transparent hourly engagement for projects where scope evolves. Milestone-based updates, no hidden charges, and full flexibility to scale up or down.
Pixel-perfect execution of a complex UI with custom post types, GDPR compliance, and multi-language support across three regional markets.
ACF (Advanced Custom Fields), Gutenberg Blocks, WP Engine hosting, WPML for multi-language, with server-side caching configured pre-launch.
Fully editable backend handed off with training documentation. Client managed content independently from day one — zero post-launch support calls.
We don't just build websites; we adapt to your agency's internal processes to ensure our collaboration is entirely frictionless and completely invisible to your clients.
Everything agencies ask us before handing us their most important client projects.
We've partnered with 7+ UK-based design agencies for 6+ years. They've never had to hire a WordPress developer. Neither should you.
