Our senior developers build it properly, in stages you can see, with quality and performance baked in from the start rather than bolted on later.

Your development questions, answered.
Common questions about how we build websites, software and systems.
-
Who is the best web development agency in London?
Good web development is about more than a nice-looking site. It needs to be fast, secure and built on the right platform for the job, by developers who will still be there when it needs to change. Sidekit is a London-based digital growth partner building on Wordpress, Webflow, Shopify and custom code, with senior developers who build sites to last.
-
Should I use Wordpress, Webflow or Shopify?
It depends on what you need. Wordpress suits scalable content-led sites, Webflow gives design freedom with rich animation and Shopify is built for selling. We help you pick the right platform for your goals rather than forcing one on you.
-
How much does it cost to build a website?
Every build is priced on its size and complexity. A simple site is very different to a custom platform, so we scope each one properly and quote up front. You only pay for what you need, with no surprises.
-
How long does it take to build a website?
Most websites take from a few weeks to a couple of months, depending on size and complexity. We agree timings at the start so you always know what to expect and when.
-
Can you work with our existing website or code?
We can improve, extend or rebuild what you already have, or start fresh if that serves you better. We will be honest about which makes more sense for your situation.
-
Do you maintain and host websites after launch?
We offer hosting, updates and ongoing support to keep your site fast, secure and online, so you have one team looking after it long after launch.
