WHAT WE BUILD

Custom web development, when a template won’t do

Custom web development is for the jobs a standard website can’t do: selling online, connecting the systems you already use, or giving customers and staff tools that don’t exist off the shelf. We build around how your business works, so you aren’t bending your processes to fit a template. On The Gift Sip, for example, we built a Next.js store that pulls products from Printify and sends each paid order straight back to it.

  • Custom websites and CMS

    Fast, maintainable sites on Next.js, WordPress or a headless CMS. Your team updates the content themselves, without calling a developer.

  • E-commerce development

    Online shops with payments, delivery rules and product data that stays in sync. Our E-commerce package starts from £1,500 for up to 50 products; see the package. Larger or more complex stores are scoped and quoted individually.

  • Integrations and APIs

    We connect your CRM, bookings, payments, email and fulfilment with error handling and logging, so a failed sync shows up for us before your customers notice it.

  • Web applications

    Customer portals, staff tools, logins and custom back-end logic, built, tested and monitored like production software. Once customers rely on it every day, that’s what it is.

CHOOSING

Does your UK business need a web development company or a website package?

Rule of thumb

  • Your site explains what you do and takes enquiriesa website package
  • It sells online, connects to your systems or has loginsa custom build

  1. A website package

    • From £400
    • Starter live in around 2 weeks
    • Fixed price

    For most small businesses, a website package is enough. If you want a straightforward site that explains your services and brings in enquiries, a fixed-price package from £400 is the better fit, and the Starter site is usually live in around 2 weeks. See our website design for small businesses and the website packages.

  2. Custom web development

    • Fixed-scope proposal
    • Priced before any code
    • No hourly billing

    You need a web development company when the site has to do something a standard site can’t, such as run an online shop, connect to your systems or let customers log in. We scope each of those projects individually and confirm the price in a fixed-scope proposal before any code is written. You don’t pay by the hour, and the invoice matches the proposal. Bespoke projects (custom AI, web development and SEO projects): 50% upfront and 50% on completion up to £5,000; above £5,000, 40% upfront, then 30% and 30% at agreed milestones.

IDEAL FOR

When you need a web development agency

  • Launching or rebuilding a site that has to be fast, secure and easy to maintain
  • E-commerce development or a headless CMS connected to your CRM, bookings, forms and payments
  • Custom features a template can’t handle: customer portals, logins, quote tools, booking flows
  • Technical SEO built in from the start, with schema, sitemaps, canonicals and crawl budget handled
  • CI/CD, preview deploys and automated tests set up on day one rather than bolted on later
  • Analytics, monitoring and error tracking that keep working long after launch

Somewhere in between? Most projects are. A short scoping call tells us both whether you need a package or a custom build, and what it will cost.

FAQ

Common Questions

How much does web development cost in the UK?

Our website packages start at £400, paid 50% upfront, 50% on launch. E-commerce development starts from £1,500 for up to 50 products, and larger stores are scoped individually. Custom web development, such as web apps, portals and integrations, is quoted at a fixed scope with the price confirmed in writing before work starts. Bespoke projects (custom AI, web development and SEO projects): 50% upfront and 50% on completion up to £5,000; above £5,000, 40% upfront, then 30% and 30% at agreed milestones. No VAT added.

How long does web development take?

A package website takes from around 2 weeks (Starter) to 4–6 weeks (Growth), and e-commerce builds start at 4 weeks. Custom web development usually takes 6–10 weeks from discovery to release, depending on scope and integrations. We confirm your timeline in the proposal, before any work starts.

Do we own the code and assets?

Yes. The repositories live under your organisation, and all source files and assets are transferred to you at completion. Nothing is locked to us, so if you later bring in another developer or agency, they can pick up the code and carry on without asking our permission.

How do you approach SEO?

Technical SEO is part of every build: schema, sitemaps, canonicals, clean URLs and fast pages. If you want ongoing rankings work after launch, our monthly SEO packages pick up from there. Each one includes a monthly report, and they’re monthly rolling with 30 days’ notice to cancel.

How do you handle quality?

Every preview deploy is checked with automated Playwright and Jest tests, WCAG 2.1 AA accessibility checks, Core Web Vitals budgets and cross-browser QA. Problems show up while we’re building, when they’re cheap to fix, instead of in a rush the week before launch.

Do you manage hosting?

Either way works. We set up CI/CD and deploy to your own infrastructure, often Vercel or Cloudflare, so long-term hosting stays your choice. If you’d rather hand it off, our Care plan (£25/mo) covers hosting, SSL, backups and updates, and it’s monthly, so you can cancel anytime.

Should we use a headless CMS or WordPress?

Whichever fits how your team already works. We use Sanity or Strapi when you want a headless CMS, WordPress when your editors already know it, and Shopify or WooCommerce for e-commerce development. If you’re not sure, we’ll talk it through in discovery and recommend one.

Can you integrate third-party tools?

Yes. We connect CRMs, email, payments, bookings, GA4, Sentry and more, with proper environment and secrets handling so API keys never leak. On The Gift Sip we connected Printify and PayPal, with webhooks tracking each order through production and shipping.

What happens after launch?

Custom builds include a 30-day stabilisation window. On packages, Business includes 30 days’ support and Growth 60 days. After that, care plans from £25/mo keep your site updated, or we can quote optimisation and new features at a fixed scope.
