Crowded local search
Search for a restaurant in Soho or an accountant in Islington and the results are packed. Slow, thin or badly structured pages lose out to competitors who got the basics right.

Web Development Company in London
Websites and web apps for London brands, restaurants, retailers and professional firms — and for the agencies that need a dependable build partner behind them. Fast on a phone with a patchy signal, accessible to everyone, and easy for your own team to update.
- Speed and accessibility tested before launch
- A CMS your team can run without us
- White-label builds for agencies, by agreement
The problem
Why London websites underdeliver.
In a city this crowded, small weaknesses — a slow menu page, a broken booking link, an out-of-date team page — cost real enquiries.
What a good London website does
- Loads quickly on a mid-range phone and a weak signal
- Works for people using screen readers and keyboards
- Lets your own team change content the same day
- Sends every enquiry and booking to the right place, tracked
Slow on a phone
People check you on a phone between meetings, on a bus or on a platform. Heavy pages, pop-ups and oversized images send them straight back to the results.
Accessibility left until last
Accessibility matters under the Equality Act and to a real audience. Retrofitting WCAG fixes after launch costs far more than building them in from the start.
A CMS nobody wants to touch
Menus, events, offers and team pages go stale because every change means emailing a developer and waiting.
Enquiries that go nowhere
Forms that land in a shared inbox, booking widgets that do not sync, and no way of telling which pages actually bring in work.
Agencies out of build capacity
The pitch is won and the designs are signed off — then the developers are booked, or the brief needs backend work the studio does not do.
Who we work with
Who we build websites for.
London businesses need very different things from the same few pages. These are the briefs we are set up for.
Menus, bookings and events kept current
Booking links that work, menus and events your team updates without a developer, private-dining and group enquiries routed to the right person, and pages that load on a phone outside the venue.
Shops that load fast and sell
Shopify (including headless), WooCommerce or Magento builds with click-and-collect, local delivery options and stock that stays in step with the systems behind it.
Sites that win the brief
Practice-area pages, people profiles, insights publishing and enquiry routing for law firms, accountancies and consultancies — structured for search and easy for marketing teams to maintain.
A build partner behind your designs
We build what your designers designed, to your standards and in your project tools — named as your partner or white-label, agreed up front.
Web apps, not just websites
Quoting tools, customer portals, booking systems and account areas for businesses whose customers would rather self-serve than phone up.
Accessible by requirement
Sites for boroughs, charities and publicly funded programmes, built to WCAG 2.2 AA, with help preparing the accessibility statement public sector bodies must publish.
Local search
Competing in London search, without the tricks.
Local search in London is crowded, and there is no trick that wins it. What works is unglamorous: fast pages, clear structure, accurate details and content that genuinely helps the person searching.
For a restaurant group or a firm with several sites, that means one properly useful page per location — the address, opening hours, the nearest stations, what is different about that site — rather than near-identical pages with the borough name swapped. It means structured data that tells search engines you are a restaurant, a law firm or an event, and names, addresses and phone numbers that match everywhere they appear, including your Google Business Profile.
We build those foundations into the site and give you the tools to keep them accurate. We do not promise rankings — nobody honest can — but we will not hand you a site that holds you back.
- Location pages with real, distinct content
- Structured data for venues, services, people and events
- Consistent names, addresses and opening hours everywhere
- Redirects mapped so a rebuild keeps the traffic you have

For agencies
A build partner for London agencies, on honest terms.
Plenty of London agencies are excellent at brand, design and campaigns and would rather not run a development team. We work as the build partner behind them: your designs, your standards, your project management tools and your client relationship.
We are happy to work white-label, with no Techsleight branding on anything the client sees, or as a named technical partner. Which one is agreed in writing before the first sprint — along with who speaks to the client, who owns the code (normally the end client), where it is hosted and who supports it after launch.
Two things we are straightforward about. We do not approach your clients for work. And we will not misrepresent who we are if a client asks us directly — so it is worth agreeing, in advance, how that question gets answered. Most agencies find that settles it.
- Builds from your design files, to your agreed standards
- Your ticketing, Slack or Teams — not another tool to check
- A non-solicitation clause in our agreement if you want one
- Hosting, support and handover terms settled before launch

How we work
How a website gets built with us.
Seven stages, whether it is a small brand site or a web app. On agency projects, we fit into your process instead of imposing ours.
- 01
Discovery
We review your analytics, search performance and current site, talk to whoever handles enquiries, and agree what the site has to achieve.
Goals, audience and content audit
- 02
Strategy
Sitemap, content model, CMS choice and a redirect plan for every URL that matters, so a rebuild does not throw away the traffic you already have.
Sitemap, CMS decision and redirect map
- 03
UX & architecture
Wireframes and designs tested on real phones — or, for agency work, a technical review of your designs before the build starts.
Approved designs and component list
- 04
Development
Two-week sprints with a demo at the end of each, code review on every change, and a staging environment your team can use.
Working software every sprint
- 05
Testing
Accessibility checks against WCAG 2.2 AA, speed tests on mid-range phones and slow connections, and cross-browser QA.
Accessibility and performance report
- 06
Launch
Go-live with redirects, analytics, search console and uptime monitoring in place — plus a training session for your editors.
Live site and trained editors
- 07
Optimisation & support
After launch we fix, measure and improve — a support retainer, a roadmap of next features, or a clean handover to your own team.

Engagement models
Ways to work with us on the web.
Businesses usually start with a discovery sprint or go straight to a fixed-price build. Agencies often find named developers or flexible hours easier to plan around client work.
Discovery sprint
From £2,000 fixed fee
You have an idea or a problem, but not yet a scope you would trust a quote against.
- Workshops with your team
- Prototype or technical spike
- Written scope, plan and estimate
Fixed-scope project
Quoted after discovery
A defined build — an MVP, a rebuild or a feature set — with milestones and a fixed budget.
- Agreed milestones and deliverables
- Milestone-based billing
- A demo at the end of every sprint
Dedicated developers
From £2,900 per developer / month
Ongoing roadmap work where you want named engineers inside your own sprints.
- Named, senior engineers
- Work inside your tools and sprints
- Scale up or down as the roadmap changes
Flexible hours
From £20 per hour
Fixes, small features and support where the work comes in bursts rather than sprints.
- Billed weekly for time used
- Daily written updates
- No long-term commitment
Prices are in GBP. Every estimate is confirmed in writing after a discovery call — the figures above are where engagements start, not a quote.
Relevant work
Products we have designed and built.
A corporate website and enquiry system for a contractor, and a grocery eCommerce platform with delivery slots — two ends of the web work we do.
All case studiesWhy Techsleight
What working with us is actually like.
The same principles whether you are a restaurant group, a law firm or an agency handing us a brief.
Product engineering, not ticket-taking
We ask what the software is for before we estimate it — and we will tell you when something should not be built, or should be bought instead.
AI where it earns its place
LLM features, retrieval and automation built with evaluation, guardrails and cost controls, and plain software where that is the better answer.
Full-stack under one roof
Design, frontend, backend, mobile, cloud and QA in one team, so nothing falls between suppliers.
UK-focused delivery
UK business hours, estimates in pounds, and a contract with a UK company. Our engineers are based in the UK and India.
Flexible engagement
A fixed-scope project, dedicated developers or a monthly retainer — and you can move between them as the work changes.
You own everything
Code, IP, cloud accounts and documentation are yours from day one. We sign an NDA before discovery if you need one.
Support after launch
We stay on for fixes, upgrades and new features, or hand over cleanly to your in-house team with the documentation to match.
FAQs
Questions we get asked.
Straight answers on scope, cost, timelines and how we work. If yours is not here, ask us directly.
How much does a website cost in London?
Mostly on how many distinct page types you need, the CMS, integrations and how much content has to be written. Discovery, from £2,000, ends in a fixed quote; smaller changes to an existing site can be done on flexible hours from £20 an hour. Everything is priced in pounds and itemised.
Do we need to meet in person to build a website?
No — web projects run remotely, with video calls, a shared channel, a staging site you can click through and a demo every fortnight. Content and design workshops run on video too, with a shared board everyone can edit.
What hours do you work, and how fast do you reply?
UK business hours, with engineers in the UK and India. Email replies come within one working day, and live projects have a shared Slack or Teams channel for quicker questions. On agency projects we can work inside your own channels and tools.
Do you work white-label for agencies?
Yes, when it is agreed up front. We build under your brand, in your tools and to your standards, and agree in writing who talks to the client, who owns the code and who supports the site after launch. We do not approach agency clients for work.
Will a new website get us to the top of Google?
Nobody honest can promise that. What we can do is remove the technical reasons a site underperforms — speed, structure, structured data, accessibility, redirects — and give you a CMS that makes publishing useful content easy. Rankings then depend on content, reputation and competition.
Which CMS should we use?
WordPress suits most marketing sites and teams that want a familiar editor and a large ecosystem. A headless CMS suits content that feeds several places — a site, an app, screens in a venue — or sites where speed and security matter most. We recommend one, and explain why, in discovery.
Is our website legally required to be accessible?
The Equality Act’s duty to make reasonable adjustments for disabled people is generally taken to cover your website as part of the service you provide. Public bodies, including London boroughs, face separate accessibility regulations and must publish an accessibility statement. We build and test to WCAG 2.2 AA; for advice on your specific legal position, speak to a solicitor.
Can you fix our current site instead of rebuilding it?
In many cases, yes. An audit of speed, accessibility and the CMS comes first; then we fix whatever costs you most — at a fixed price where the scope is clear. Rebuilding only makes sense when the platform itself is the problem.
Who owns the website once it is built?
You do: the code, the designs, the content and the hosting and domain accounts, set up in your name. On agency projects, ownership normally passes to the end client, and we agree that with you in writing before work starts.
Can you connect the site to our booking, CRM or till system?
Usually, through the supplier’s API or webhooks. We check what your booking, CRM or point-of-sale system actually exposes during discovery, and if it has no usable API, we tell you before designing a workaround.
