Expert WordPress Customisation that fits.

Need to edit an existing WordPress site, fix Elementor or Divi layouts, extend a theme, build a custom section or rescue a legacy build? We customize WordPress carefully, respecting the site you already have while cleaning up the parts that slow you down.

Our approach

Clean code, native feel .

A good customization should feel like part of the original site, not a bolt on. Our developers audit your theme, plugins and page-builder setup first so new sections, templates and features slot in cleanly.

Whether it is an Elementor repair, a Divi template cleanup, a custom Gutenberg block, a WooCommerce tweak or an API connection, we build it to be stable, documented and easy to maintain.

  • Theme, template and page-builder customization
  • Elementor, Divi, WPBakery and Beaver Builder fixes
  • CRM and API integrations (Salesforce, HubSpot, Zapier)
  • Legacy site rescue and modernisation

How it works

Concept to integration in four steps.

A careful approach to adding features to your existing WordPress site without introducing bloat or technical debt.

01

Technical audit

We review your current site architecture, plugins and theme to confirm the requested features can be integrated safely and efficiently.

02

Development

Features are built on a staging environment using clean, documented code that follows WordPress coding standards and your existing patterns.

03

QA and testing

We test for browser compatibility, plugin conflicts, performance regressions and accessibility before anything goes live.

04

Deployment

Once approved, we push changes to production with zero downtime and provide a walkthrough of how to manage the new functionality.

Lighthouse 95+ preserved

New features never drop your existing performance score. Measured before and after on staging.

Core Web Vitals pass

LCP under 2.5s, CLS under 0.1, INP under 200ms. Verified on real device emulation.

WCAG 2.2 AA compliant

Keyboard navigation, semantic HTML, ARIA labels and contrast checked against the latest standard.

Update safe code

Child themes, custom plugins and hooks. Your changes survive WordPress, theme and plugin updates.

Nonces, capability checks, sanitisation and escaping on every input and output we touch.

Cross browser tested

Verified on Chrome, Safari, Firefox, Edge and real mobile devices before your staging review.

Clean, documented code

PSR standards, WordPress coding conventions, inline docs and a handover README your team can read.

Plugin conflicts resolved

We diagnose on a staging copy, isolate the root cause and fix cleanly. No silent workarounds.

Backed by real QA

Functional QA, visual QA and regression QA on the full site before anything touches production.

For agencies

Your clients. Our code. Your brand.

We are the silent development team behind dozens of design and marketing agencies. Your client sees your work, your invoice and your brand. Our name never appears on the feature, the commit or the handover.

    One point of contact for all your customisation work. Shared Slack channel, weekly syncs, fast replies.

  • 03

    Transparent partner pricing

    Retainer rates, bulk discounts and priority scheduling for agency partners.

  • 04

    Your process, not ours

    We plug into your Figma, ClickUp, Notion or Linear. No tool switching, no friction for your team.

Become a partner

How it works

01
Step 1

Brief the feature

You share your client's customisation request in your stack. Figma, ClickUp, Notion, wherever you already work.

02
Step 2

Scope and partner quote

We write a detailed spec and send you a partner rate quote. Never shown to your client.

03
Step 3

Add margin, quote your client

You mark up, brand the proposal and present it on your letterhead at your price.

04
Step 4

Client approves the scope

Your client signs off on your terms, with your brand, and pays you directly.

05
Step 5

We build under NDA

Silent build on branded staging. No logos, no footer credits, no email signatures from us.

06
Step 6

Deliver as your own

You review, accept handover and deliver the shipped feature to your client under your agency name.

Common questions

What people ask us about customisation.

Do you work on Elementor, Divi, WPBakery and Beaver Builder sites?

Yes. We fix responsive issues, broken widgets, spacing problems, shortcode bugs, custom sections, landing pages and template conflicts in Elementor, Divi, WPBakery, Beaver Builder and similar page-builder setups.

Can you customize an existing WordPress site without rebuilding it?

Yes. We can adjust themes, headers, footers, archive templates, single post templates, landing pages, forms, menus and plugin-driven sections while keeping the existing site live and maintainable.

Can you customise third party themes?

Yes. We extend themes such as Astra, GeneratePress, Kadence and bespoke builds using child themes and custom plugins so your changes are never lost during theme updates.

Do you work with legacy WordPress sites?

Often. We specialise in rescuing sites that have become hard to maintain, modernising the code and database while keeping the site live and traffic stable.

Can you connect WordPress to my CRM?

Yes. We build custom integrations for Salesforce, HubSpot, Pipedrive, Zoho, Mailchimp and most REST or webhook based services so data syncs reliably in the background.

Do you fix plugin conflicts and broken updates?

Yes. We diagnose conflicts on a staging copy of your site, isolate the root cause and fix it cleanly rather than patching over it with workarounds.

How fast can you start?

Small feature work usually starts within a week of the scoping call. Larger integrations are booked into our schedule with a firm start date and fixed quote.
