WORDPRESS, ECOMMERCE AND CUSTOM WEB DESIGN
Portsmouth Website Design & Development Services
Website design and development covers a wide range of requirements, and creating a website that delivers actual business results often depends on how your organisation attracts customers, manages enquiries and supports its wider digital marketing strategy. From website speed and user experience to SEO performance, integrations and scalability, every element plays a role in helping your website become a valuable business asset rather than simply an online brochure.
From North Harbour to Southsea, we work with Portsmouth-based organisations ranging from professional service firms and construction businesses to healthcare providers, tourism companies and fitness centres, each with their own objectives and technical requirements. Some are looking to replace an outdated website with a modern WordPress platform that supports lead generation and marketing activity, while others require bespoke development, WooCommerce functionality or a seamless migration that preserves existing visibility and performance.
To make it easier to explore the most relevant solutions, our website design and development services are structured into dedicated areas covering different website types, platforms and technical requirements. This provides Portsmouth businesses with a clearer understanding of the options available while demonstrating how our in-house designers and developers create websites that are secure, scalable and built to deliver long-term value.
WordPress Websites
We design and develop fast, secure and flexible WordPress websites for Portsmouth businesses. Using our proprietary SDK (a lightweight modular framework that avoids bloated page builders) we give local teams full editing control while keeping performance at the core.
The result is a high-performing site with clean code, easy content management and SEO-ready structure from day one.
WooCommerce Websites
Our WooCommerce builds are tailored around product discovery, navigation and conversion, with smart filters, custom checkout flows and mobile-friendly layouts as standard.
Whether you’re migrating from another platform or scaling an existing store, we help Portsmouth retailers and suppliers create online stores that deliver a seamless customer experience and are simple to manage behind the scenes.
eCommerce Websites
From custom product pages to optimised checkout funnels, our eCommerce websites are built to convert. Whether you’re using WooCommerce, Shopify or Magento, we deliver fast, scalable stores with advanced features and smart integrations.
From advanced filtering to connected systems, our responsive designs reduce friction and creates a seamless user experience that ultimately drives sales for your Portsmouth-based business.
Bespoke Websites
We design and develop custom websites from the ground up, tailored to your structure, goals and brand. From brochure sites and white label builds to complex headless projects using React, XJS and WordPress, all our websites are bespoke, fast and built to scale.
Whether you need custom theme development, social feed integrations or a unique front-end experience, we deliver flexible solutions to Portsmouth businesses without the limitations of off-the-shelf templates.
Website Migrations
Replatforming doesn’t have to mean disruption. Our team near Portsmouth handles end-to-end website migrations, including SEO and website traffic preservation, content transfers, redirects, performance improvements and CMS improvements.
Whether you’re moving to WordPress or rebuilding from scratch, we make the process smooth, secure and search-engine safe.

FREQUENTLY ASKED QUESTIONS
Cant find the answer you are looking for?Get in touch and we will be happy to help
Q. How long does it take to build a website?
Most projects take up to 16 weeks, depending on scope and functionality. Smaller brochure sites move quickly, while larger platforms with custom features or eCommerce can take longer. We’ll always give you a clear timeline with milestones so you know what to expect.
Q. Will there be any training provided on how to use and manage the site?
Yes. Once your site is live, our website support team provide tailored training either 1:1 or via recorded video walkthroughs, to help your team feel confident updating content, managing media and making structural changes through the CMS.
Q. What platforms or CMS do you work with?
We primarily build with WordPress and our own developer-approved SDK, but also work with Shopify, Magento and modern headless stacks like React and Next.js. As a Portsmouth web development company, we’ll recommend the best-fit solution based on your goals, internal capabilities and future plans.
Q. How much do your websites cost?
Costs vary depending on size and complexity. A simple brochure site will naturally be more affordable than a large-scale eCommerce build with custom integrations. We’re upfront about pricing and can also suggest phased approaches for growing Portsmouth businesses that want to scale in stages.
Q. What is the process for feedback, revisions and approvals?
Each stage of the process includes clear opportunities for feedback and approval, with agreed review points before the project progresses. Designs are shared openly for discussion and refinement, and development only begins once sign-off is in place, helping ensure changes are made collaboratively and at the right stage.
Q. What’s the difference between a custom WordPress site and a headless website?
A custom WordPress site uses the traditional CMS with everything closely connected – ideal for Portsmouth businesses that need control and easy editing for their marketing team. A headless website separates the backend from the frontend, giving you lightning-fast performance, modern technologies like React or Next.js, and flexible integrations with third-party tools.
Q. Will my new website be optimised for SEO?
Yes, our web developers build every site with SEO in mind from day one. That means fast loading times, mobile-first design, clean semantic code, schema markup and optimised metadata. If you’re moving from another platform, we’ll manage redirects and preserve rankings so your Portsmouth business doesn’t lose visibility.
Q. Do I need to rebuild from scratch or can you improve my existing website?
It depends on your goals and how your current site was built. If your site has a strong foundation, we can often make performance, design and usability improvements without starting from scratch. But if it’s holding back your growth, whether due to bloated code, poor structure or limited flexibility, investing in a brand new website may be more cost-effective in the long run.
Q. Will my website be mobile-friendly?
Absolutely. Mobile usability is standard in our process, and every website is tested across devices and browsers. This matters in a city like Portsmouth, where mobile-first browsing is common across sectors from retail to hospitality.
Q. What is a CMS and which one should I use?
A CMS (Content Management System) is what allows you to manage your website content without needing a developer. We typically recommend WordPress for its flexibility, SEO-friendliness and ease of use, but we also build with modern frameworks for clients who need more advanced content workflows or eCommerce capabilities like an online store.
Q. What’s your approach to web design and development?
We take a strategic, user-first approach. Our process starts with discovery and planning, where we explore your goals, customers and target audience. From there we develop wireframes and design concepts that align with your branding services and business needs. We then build clean, high-performing websites that support long-term growth.
Q. How do you keep websites performing after launch?
We don’t walk away once a site goes live. Our aftercare includes technical maintenance, SEO checks, CRO improvements and ongoing support. Many Portsmouth clients continue working with us long-term because they see consistent improvements rather than one-off fixes.
Q. What makes boxChilli different from other web agencies?
We’ve been building websites since 2006 and have grown up alongside Portsmouth’s business community. All work is done by our in-house team of designers, developers and SEO specialists – no outsourcing, no shortcuts. That mix of local insight and technical expertise means we can create websites that are both high-performing and relevant to your audience.
Q. We have a limited budget, will you still work with us?
We’re happy to scope projects of different sizes and suggest phased approaches where possible. If a full custom build isn’t viable right now, we can offer scaled-down solutions or roadmap support to help you move forward strategically.
Q. What are your values and how do they shape the work you do?
At boxChilli, our core values (integrity, creativity and client focus) are built into everything we do. We’re honest about what will work, proactive in solving problems and always shape our recommendations around your business goals and data. Our work goes beyond the website – it’s part of your broader digital strategy and supports the digital services that keep your business moving.
