Website development services cover everything it takes to design, build and keep a business website working: UX and visual design, front-end and back-end code, integrations, UK hosting, accessibility, speed and the technical SEO foundation. TechAuditPros builds custom sites for UK businesses on Next.js and React — mobile-first, 90+ Core Web Vitals, structured for Google and AI search — and keeps improving them for one agreed monthly fee, instead of an upfront agency project fee followed by a separate maintenance retainer.

What a Business Website Has to Do in 2026

Three jobs your site has before design even matters.

📱

Work on a Phone First

Most of your visitors arrive on a phone and Google indexes the mobile version of your site. If it is hard to tap, read or load on a mid-range Android, it is losing customers you never hear about.

Load in Under 2.5 Seconds

Core Web Vitals are both a ranking signal and a conversion signal. We engineer to LCP under 2.5s, INP under 200ms and CLS under 0.1 as the build standard, and you can verify it in PageSpeed Insights yourself.

🔎

Be Readable by Google and AI

Semantic markup, structured data and answer-first content so search engines rank it and AI assistants can quote it — increasingly the difference between being found and being invisible.

What’s Included

Eight services, one team, one monthly engagement.

From the first wireframe to the hundredth update — design, engineering, hosting and maintenance are not separate invoices here.

🎨

Custom Website Design

UX research, wireframes and a clickable prototype you approve before code — designed around your customers and your conversion path, not a theme.

⚙️

Front-End Development

Next.js, React and TypeScript, built component by component, with nothing along for the ride that your business does not need.

🗄️

Back-End Development

Node.js APIs, PostgreSQL, authentication, payments and third-party integrations — the part that makes a site do work rather than just display.

🛒

E-commerce Builds

Shopify where its ecosystem fits, headless or custom storefronts where it does not — fast product pages, clean checkout, stock kept in sync with your back office.

🔑

Web Apps & Customer Portals

Logins, dashboards, quoting and booking tools connected to your CRM, ERP or payment provider — the same engineering standard as the public site.

🔄

Redesign & Migration

Full 301 redirect maps, ranking content preserved, indexing verified in Search Console — so a redesign never costs you the traffic you already earned.

🚀

Speed & Core Web Vitals

Image pipelines, code splitting, caching and hosting tuned to 90+ scores — on your new site or the one you already have.

🛠️

Maintenance & Support

New pages, content changes, dependency and security updates, uptime and speed monitoring every month, by the team that built the site.

You See the Design Before a Line of Code Is Written

Every build starts with a real design pass — wireframes first, then a clickable prototype you review and approve — not live editing on a template. Your engineering team walks you through the structure, the content plan and the conversion path before development starts, so the build follows a plan you have already signed off rather than a guess that gets corrected in invoices.

The Stack We Build On

Named technologies, so you can check we know them.

Agency pages list logos; here is what each layer is and why it is in your build. Everything is mainstream and open source, so any developer can pick it up after us.

⚛️

Next.js & React

The front end. Server rendering and static generation for speed and crawlability, with React components for anything interactive.

📘

TypeScript

Typed JavaScript, so whole classes of bug are caught before your users find them — and so the code stays readable for whoever maintains it next.

🟩

Node.js APIs

The back end. REST and GraphQL endpoints, authentication, webhooks and the integrations that connect your site to the tools you already run.

🐘

PostgreSQL

The database. Relational, proven and portable — your data in a standard format you can export or move at any time.

☁️

UK Hosting & Edge

Vercel’s London edge, AWS London (eu-west-2) or Google Cloud europe-west2, in an account you own, with CDN caching, TLS and automated backups.

🔗

Integrations

Xero, Sage, QuickBooks, Shopify, WooCommerce, Stripe, GoCardless, HubSpot, Salesforce, Google Analytics 4 and Search Console — built on official APIs.

Written, reviewed, handed over.

Written

Code, not a page builder.

Which is why it stays fast when you add the fiftieth page, and why another developer can pick it up.

Builder vs. Template vs. Custom

Three ways to get a UK business website — compared honestly.

A DIY builder is genuinely the right answer for some businesses. Here is how to tell which column you are in before you spend anything.

DIY website builderTemplate / theme siteCustom build (TechAuditPros)
Speed & Core Web VitalsOften poor; little control over scripts, fonts and imagesVaries; plugin stacks slow down as features are addedEngineered to 90+ from the start; nothing unnecessary ships
DesignPreset blocks; looks like every other site on that builderA theme thousands of sites share, restyledDesigned around your customers and your conversion path
SEO, AEO & GEO controlLimited technical control; basic schema at bestDepends on plugins and the theme’s markupFull control of markup, structured data, redirects, speed and AI-search readiness
IntegrationsWhatever the builder offersPlugins, with compatibility and security upkeep on youDirect integration with Xero, Sage, Shopify, Stripe, your CRM or ERP
UK complianceCookie banner bolted on; data location often unclearDepends on the plugins you installUK GDPR and PECR designed in, data hosted in a UK region, DPA signed
AccessibilityWhatever the template doesTheme-dependent, rarely testedBuilt to WCAG 2.2 AA practices and tested with a keyboard
OwnershipYou rent it; leaving means rebuildingYou own the files; theme and plugin licences continueYou own the code, content, domain and hosting outright
Cost pattern£10–£30 a month, your own time as the labourA few thousand upfront plus maintenanceOne agreed monthly fee covering design, build and updates
Best forVery early businesses testing an ideaSimple brochure sites with no growth plansUK businesses where the site has to win customers and keep improving

Third-party figures are typical published UK market pricing as of September 2026 and vary with scope.

How We Build It

Six steps, from discovery to a site that keeps improving.

1

Discovery

Your business, customers, goals and your current site’s real data — what converts and what does not — before a wireframe is drawn.

2

Wireframes & Design

Structure first, then visual design and a clickable prototype you approve.

3

Build in Sprints

Next.js and React development in two-week sprints, reviewable on a staging URL as it comes together.

4

Content, SEO & Accessibility

Page copy, structured data, redirect map, indexing and WCAG checks set up so the site is ready to rank and usable on day one.

5

QA & Launch

Cross-device and browser testing, Core Web Vitals verification on a real mid-range phone, then a careful production launch.

6

Maintain & Improve

Updates, new pages and conversion improvements every month by the team that built it, with a written report of what shipped.

Cost & Timeline

What a website actually costs a UK business.

Most UK agency pages make you request a quote to learn anything at all — the current top-ranking one shows no pricing whatsoever. Here is the honest picture, with published figures where they exist.

DIY builder £10–£30

Per month, plus your own time

  • Fine for testing an idea or a one-page presence
  • Speed and technical SEO largely out of your hands
  • You are the designer, copywriter and maintainer
  • You rent the platform; leaving means rebuilding
TechAuditPros Let’s talk

Scoped on the call and put in writing

  • Design, custom Next.js and React build, UK hosting setup and ongoing updates included
  • First live version in 4–8 weeks
  • 90+ Core Web Vitals and the technical SEO foundation built in
  • You own the code, content, domain and hosting
  • Month to month; stop any time and the site is yours
UK agency £20–£150/hr

Clutch UK directory, most £40–£80

  • Minimum project sizes commonly above £8,000
  • Change requests and new pages billed after launch
  • Maintenance retainer quoted separately
  • Three to six month timelines are common

Agency rates and minimum project sizes are from Clutch’s United Kingdom web-development directory, read 3 September 2026, converted from the USD figures it publishes; they vary by agency and scope. Our number is fixed in writing before work starts.

Real Engineers, Overnight Progress, Your Mornings for Decisions

The people writing your site’s code are engineers you can talk to directly, not page-builder operators. Working from Kochi — 4.5 hours ahead of London in summer, 5.5 in winter — they turn the feedback you leave at the end of your day into a new staging build, with a live overlap window every UK morning for calls. That is also why the sites hit 90+ Core Web Vitals: they are engineered, file by file, rather than assembled from plugins.

FAQ

Website Development in the UK: Frequently Asked Questions

It depends on which of three routes you take, and the honest ranges are public. A DIY builder subscription runs roughly £10–£30 a month plus your own time. UK agencies listed in Clutch’s directory charge £20–£150 an hour, most commonly £40–£80, and set minimum project sizes commonly above £8,000 — with maintenance quoted separately afterwards. TechAuditPros works differently: design, custom build, hosting setup and ongoing updates are one agreed monthly fee, scoped on the call and put in writing before anything starts, with no upfront project fee and no separate maintenance invoice.

Everything between an idea and a site that earns its keep: UX and visual design, front-end and back-end engineering, content structure, integrations with the tools you already run, hosting setup, accessibility, speed work and the technical SEO foundation — then ongoing updates once it is live. If a supplier quotes only “design and build”, ask who owns speed, indexing and the first year of changes.

Most UK business websites go from approved design to a live first version in 4–8 weeks. Larger builds — online shops, customer portals, sites with hundreds of pages — are phased so something useful ships early and the rest follows in two-week sprints you can review on a staging URL.

Most sites are custom-built on Next.js and React for speed, security and control. When a business genuinely needs Shopify’s ecosystem for retail, or WordPress because an in-house team must edit everything daily, we say so and build on it properly — hardened, fast and without a plugin stack that rots. We choose what fits your business, not what is quickest to template.

We build to 90+ Core Web Vitals: Largest Contentful Paint under 2.5 seconds, Interaction to Next Paint under 200 milliseconds, Cumulative Layout Shift under 0.1 — measured on a mid-range Android over 4G, not on a fast laptop. Speed is a build standard here, not a fix bolted on later, and you can verify it yourself in PageSpeed Insights the day it goes live.

Yes. Clean semantic markup, structured data, a sensible URL and internal-linking structure, and answer-first content so Google can rank it and so ChatGPT, Perplexity and AI Overviews can quote it. The team that builds the site also runs SEO, AEO and GEO, so there is no gap between what gets built and what gets found.

Yes, and this is where most redesigns go wrong. Rankings are lost when URLs change without redirects and ranking content quietly disappears. We map every old URL to its new home with 301 redirects, keep or improve the pages that already earn traffic, and verify indexing and Search Console coverage after launch. It is a standard part of every redesign, not an upsell.

You do — the code, the content, the domain and the hosting account, all in your name from day one. If you ever move to another supplier or in-house, everything comes with you and nothing is locked behind a proprietary builder or our accounts.

On modern infrastructure in a UK region — Vercel’s London edge, AWS London (eu-west-2) or Google Cloud europe-west2 — inside an account you own, so personal data stays in the UK. Forms, analytics and cookie behaviour are built to UK GDPR and PECR: consent before non-essential cookies, a lawful basis for every form, and a data processing agreement between us. Hosting for a typical business site costs a few pounds to a few tens of pounds a month, and we set it up and manage it.

We build to WCAG 2.2 AA practices — semantic markup, keyboard navigation, visible focus, colour contrast, alt text, labelled forms — because accessible sites are also faster, easier for Google to parse and legally safer under the Equality Act. For a formal accessibility audit or statement we work alongside your compliance adviser.

Yes. New pages, content changes, dependency and security updates, uptime and speed monitoring, and small improvements are part of the monthly engagement, handled by the same team that built the site. There is no separate maintenance plan, and no ticket queue between you and the people who know your codebase.

Yes. If you have a brand system or an in-house designer, we build to it and take the engineering, performance, accessibility and SEO. If you do not, design is included — you approve wireframes and a clickable prototype before any production code is written.

Our engineers work from Kochi, 4.5 hours ahead of London in summer (BST) and 5.5 ahead in winter (GMT). You get a live overlap window every UK morning and early afternoon for calls, Slack or Teams, anything you send at the end of your day is picked up before ours ends, and you get a weekly demo on a staging URL plus a monthly written report. We have no UK office and say so up front: if you need someone on site, we are not the right fit.

Three things, plainly. Real engineers write your code rather than page-builder operators, so 90+ Core Web Vitals is a standard rather than a hope. The same team runs your SEO and, if you need it, the internal software behind the site — so nobody can blame another supplier. And the commercial model is one agreed monthly fee instead of an upfront project fee followed by change-request invoices. We are also new to the UK market and open about it: our delivered work is in North America, Australia and the Gulf.
