Web design agency | Web design London

Plug & Play is a creative web design agency in London and Surrey. Established in Guildford, Surrey in 2006. We’re specialists in the delivery of digital and design projects including websites, brand development, eCommerce, mobile apps, digital transformation, UX design and digital marketing strategy.

In 2025, our clients are a mix of SMEs and larger corporate clients, looking for the creative solutions to meet their business goals. Most of our clients are based in and around Guildford, Surrey and London.

Our process

Our process starts with one of our web designers creating wireframes of the new website structure. They will gradually increase the fidelity of the prototype to create a final design to hand to our developers.

Once the designs have been signed off, our developers begin work building the new website. This can take several weeks or even months, as some web projects are extremely complex. Once the initial design work is complete, our Quality Assurance testers review the website across a range of browsers and devices. The web developers then resolve any bugs raised by the QA team before the completed project is handed over to the client.

What types of websites do we build?

As an agency, we are platform agnostic and will recommend the most suitable platform and content management system for each client. Many of our websites are built on WordPress as it is a popular CMS that many of our clients have experience using. WordPress has a fantastic ecosystem of plugins and developers. It has become popular because of the flexibility it provides users.

Our web development agency London codes websites on platforms such as WooCommerce, Magento, Shopify, Squarespace and Craft.

Our project types include multi-regional and multilingual web design where our clients target an international audience. We deliver custom website design, web development, website rebuilds and replatforming, Headless websites, and eCommerce web design.

What industries do you work with?

Our clients are typically looking to improve the performance and usability of their websites and our agency team is specialised in delivering upon these objectives across a wide range of sectors. Rather than working within a single industry, we apply design and development best practice to all of our website projects and provide cross-sector insights that generate results.

Some industries that we work prominently within include school web design, recruitment website design, architect websites, fintech websites, crypto website development, charity and not-for-profit sectors, and the construction industry. We also partner with Private Equity Firms to transform their portfolio businesses with digital infrastructure and marketing.

What makes a successful web project?

A successful website is more than an attractive design. Rather, it must act as an online business tool to help generate new leads, sales and customers. This is achieved by delivering the website alongside an SEO strategy to secure search engine rankings, and building the site with a quality code base. This strategic approach enables the business to reach their target customers and position their on-page content and copy to convert website visitors into customers.

At Plug & Play, our web design team maps out the user journeys before any design work starts, creating clickable prototypes around conversion design best practice.

Of course, a successful website will also have a strong and consistent brand identity, and an interactive user experience.

What exactly does a website agency do?

The type of professional services that are offered varies by design company. Of the top 100 digital agencies surveyed by eConsultancy, 22% focus primarily on designing and building websites, 15% focus only on the technical aspects of digital services, 5% are purely creative agencies, and 58% are classified as full service or marketing companies.

Even in the case of full service agencies, their specialisms and offerings will vary. Sometimes it is better to engage with a web design agency that has a good track record in a single specialism than a studio that does a bit of everything to a mediocre standard.

Who uses a web design agency?

A wide range of industries engage in web design services, with the largest sectors generally being retail and financial services, followed by travel and leisure. If a company operates on the internet in any way, they can find benefit from hiring an agency team. At Plug & Play we have clients from a wide range of different sectors and we’ve presented a fraction of these as case studies across our site.

Once a web design has been handed over, our clients add their content. Once content has been entered, the Quality Assurance testers in our team review the website for any outstanding bugs. Our marketing team undertake SEO optimisation work on the site based on recommendations from the digital strategy. Once this is complete, the project is complete and can go live.

Post-launch, the majority of our clients choose to move to a retainer for ongoing website support. This enables them to continue to innovate online.

Have you won any awards?

We are well recognised within our industry, including at The Drum Design Awards, The Webbys, The Wirehives, Awwwards, CSS Design Awards, Clutch Leaders, eCommerce Awards and many more.
