Web development · Surrey, UK
Fast, secure, hand-built websites and web apps for businesses across Surrey and beyond — properly engineered, and looked after long after launch.
Seven recent builds — click, drag or use the arrow keys to flip through.
Why builds fail
When we are asked to rescue a site, it is rarely one dramatic fault. It is four ordinary ones that were never dealt with.
Every plugin is someone else’s code running on your site. Stack enough of them and you inherit their bugs, their security holes and their update schedule — and one bad release can take the whole thing down.
Uncompressed images, scripts loading in the wrong order, a database nobody has tidied since launch. Speed decays quietly until visitors start leaving before the page has drawn.
Out-of-date software is how most small business sites get compromised. If no one is patching it, the site is not standing still — it is slowly becoming a liability.
A build that needs a developer for every price change or new page will not keep up with your business. The parts you want to edit should be yours to edit.
What we build
Built to do exactly what your site needs — not a general-purpose theme carrying features you will never use.
Pages, projects, news and team set up as editable content, so your team keeps the site current without us.
Product catalogues, payments and shipping, built to handle a real order flow rather than a demo one.
Logins, self-service listings, search and filtering when your site needs to do more than present pages.
Booking systems, CRMs, payment providers and third-party APIs wired in so data moves without anyone re-typing it.
Compressed images, optimised script loading, HTTPS, hardened configuration and monitoring from day one.
How we work
What the site has to do, what it has to talk to, and what you need to manage yourself. Getting this right is what stops a build sprawling later.
WordPress where you need to manage a lot of content, hand-coded where speed and security matter more. We recommend the one that fits, not the one we would rather sell.
Responsive across real phones, tablets and browsers — not just a narrow window on a desktop. Forms, payments and integrations tested end to end before launch.
Migration, redirects and search setup handled. Then patching, image compression, speed checks and security monitoring so the site stays healthy.
After launch
Every plan is tailored to how your site is actually built. Tell us what yours needs.
Third-party software, plugins and themes kept patched and up to date
Images compressed and scripts loading optimally as the site grows
Regular security checks so a compromise is caught early, not by your customers
Content and page changes handled for you on the fuller plans

castellum.co.uk Reviews
Working with Ed Laycock and the team at Cumulus Digital to build our new website has been incredibly easy — a service second to none. I have been incredibly impressed by their knowledge, expertise and the speed at which they turned this around. Our new website has been well received universally.
Castellum — award-winning construction
Ed at Cumulus Digital was recommended to me when I started exploring having a new website created. This is not a world I know much about; they were excellent at guiding me through the process and hand-held me every step of the way. I have no hesitation in recommending them.

We found Cumulus Digital to be very helpful and efficient in handling our web site build and deployment. We relied on their experience to navigate us through the migration, and will continue to use Cumulus Digital for new requirements on an ongoing basis.
Website build & migration client
We started working with Cumulus Digital back in 2016 when we decided we needed a new, more up-to-date website. During the design stage, they recommended a complete brand styling change which we agreed to and have never looked back.
Client since 2016 — brand & website
Cumulus Digital understood our business needs and helped revamp our branding, literature and website.

Common questions
Both, depending on the job. Where you need to manage a lot of content yourself, a properly built WordPress site makes sense — AssetQ and Castellum are both CMS-driven. Where speed and security matter more than day-to-day editing, hand-coded is better. We will tell you which fits rather than defaulting to one.
Usually, yes. We start with an audit of what is there — how it was built, what is out of date, what is holding back speed — and give you an honest view on whether it is worth improving or rebuilding. We have taken over and migrated existing sites before, including moving AssetQ into a Google Cloud hosting environment with downtime monitoring.
Yes. We have built e-commerce for a Cobham salon moving its hair and lifestyle products online, and for an electric motocross brand with a wide and varied product range. Catalogue, payments, shipping and stock all get set up so you can run orders properly from day one.
That is the development end of what we do. Hersham Village runs a searchable business directory where owners claim and manage their own listings through self-service accounts, alongside village news and events. If your site needs to do something rather than just say something, tell us what.
A website is not a fire-and-forget purchase. Our maintenance plans keep software patched, images compressed and scripts optimised, with regular checks that the site has not been compromised. Plans run from bare-bones cover for simple sites to monthly care including content changes and new pages.
Yes, entirely. The site, the domain and the hosting account are yours, and they stay yours if we ever part ways.
