White-label WordPress development for UK agencies

Your agency and client relationship. Experienced WordPress delivery behind the scenes.

Confidential overflow development, troubleshooting, WooCommerce, integrations and reserved technical capacity from an Essex-based UK partner.

Add experienced WordPress capacity without adding permanent headcount.

A busy design or marketing agency should not have to decline good client work because an inherited WordPress website develops a difficult fault or a project needs deeper technical delivery than the internal team can provide.

Web Wonderland works as a confidential extension of your agency. You control the commercial relationship and client communication while we handle the agreed investigation, development, testing and handover behind the scenes.

Use the desk for one defined technical issue, a reserved rescue day, recurring overflow capacity or a separately scoped build. Every engagement starts with a clear brief and ends with work your team can review and confidently present.

Your Client
You retain the relationship, commercial ownership and final communication. We remain behind the scenes unless another arrangement is agreed.
Your Workflow
We can work with your repository, staging environment, ticketing process and review conventions rather than imposing a separate delivery system.
UK-Based Delivery
Web Wonderland is based in Chelmsford, Essex, and supports design, marketing and digital agencies throughout the UK.

Confidential agency enquiry

Tell us where your WordPress delivery needs support.

Share the delivery problem, the result your agency needs and what project materials are available. We will review the fit, confirm the scope and arrange any NDA or secure access separately.

Please do not send passwords, login details, API keys or other access credentials through this form. If access is needed, we will arrange a secure method after reviewing your enquiry.

Fields marked * are required.

Package *

A public or staging address is enough. Do not include login details in the URL.

Use a project reference instead of confidential client information if preferred.

Tell us what exists; we will arrange any secure transfer or access separately.

Need something outside these packages? Use our full contact form for unusual or wider projects.

WooCommerce faults and operational fixes.

WooCommerce faults and operational fixes.

Checkout failures, transactional email problems and conflicts between WooCommerce extensions can quickly become agency-critical.

We reproduce the issue, trace the code and configuration involved, then make the smallest responsible change that meets the agreed acceptance criteria. Where the problem sits with hosting or a third-party platform, we document that clearly for your team.
Brief a WooCommerce issue
Forms, APIs and connected WordPress systems.

Forms, APIs and connected WordPress systems.

We support Contact Form 7 integrations, webhooks, CRM connections, booking journeys and suitable third-party APIs when data is not reaching the right place or a new workflow needs to be implemented.

The brief, data handling, failure states and expected output are agreed before delivery so your agency has a reviewable result rather than an unexplained patch.
Discuss an integration
Themes, builders and compatibility work.

Themes, builders and compatibility work.

Inherited Salient and WPBakery websites, commercial themes and long-lived plugin stacks often need experienced intervention without forcing an unnecessary rebuild.

We can handle responsive layout defects, PHP compatibility updates, JavaScript conflicts, hooks, templates and controlled customisation while preserving the parts of the client website that already work.
Share an inherited build
Custom plugins, tooling and performance fixes.

Custom plugins, tooling and performance fixes.

Agency requirements do not always fit an off-the-shelf plugin. We can repair or extend custom plugins, build focused import and export tools and resolve performance-related code problems.

Security-hardening changes can also be delivered within a defined scope, without making unrealistic promises of absolute security or disguising an incident that needs specialist response.

Designed to fit the way your agency already works.

You can keep us entirely behind the scenes or agree a limited client-facing role when a technical meeting would help. NDA requirements, communication channels and the use of your project-management tools are confirmed before delivery.

Repositories and staging environments are preferred because they create a clean review path, but inherited websites do not always arrive in ideal condition. We will explain what is needed and arrange credentials or files securely after qualification.

For recurring allocations, your agency owns the priority list. We make capacity, dependencies and work completed visible so reserved days remain commercially useful rather than disappearing into an open-ended support arrangement.

Confidential By Default
Agency ownership, client contact, portfolio permissions and NDA requirements are agreed before project information is shared.
Staging & Source Control
Changes are prepared through an appropriate repository and staging route where the available website setup allows it.
No False Guarantees
Risks, external dependencies and security limitations are made clear rather than hidden behind an unrealistic promise.

Frequently Asked Questions
+
White-label WordPress development gives an agency additional technical delivery capacity under its own brand. The agency retains the client relationship and commercial ownership while Web Wonderland completes the agreed development, testing and handover behind the scenes.
+

+
Typical work includes WooCommerce faults, Contact Form 7 and API integrations, Salient and WPBakery customisation, PHP compatibility, JavaScript conflicts, custom plugin repairs, import and export tools, performance-related code fixes and proportionate security-hardening changes.
+
Yes. We can work with an appropriate source-control repository, staging environment and your preferred project-management workflow. If the inherited website lacks these foundations, we will explain the safest practical review and delivery route before work begins.
+
Send the project or client reference, public or staging URL, the visible problem or requirement, reproduction steps where relevant, the expected outcome, available repository or files and the required timescale. Do not send passwords, API keys or other access credentials through the enquiry form.
+
The published packages have clear prices, but work only starts after the written deliverables, assumptions and acceptance criteria are confirmed. Larger builds, third-party costs and requirements outside the selected package are quoted separately before delivery.

Yes. Web Wonderland is based in Chelmsford, Essex, and supports design, marketing and digital agencies throughout the UK using remote collaboration, secure access, staging and source-controlled delivery workflows.
