Removed functions, stricter typing and deprecation notices fixed systematically, with Rector for the mechanical changes and PHPStan to catch the rest.

Capabilities
PHP capabilities we bring to your product.
Plenty of UK businesses still run on PHP written a decade or more ago. Our PHP developers are chosen for making that code safe and changeable again, without a risky rewrite.
Tests around untested code
Characterisation tests that pin down what the code does now, so it can be refactored and upgraded without changing behaviour by accident.
Security fixes
SQL built from strings replaced with prepared statements, output escaped, weak password hashes upgraded at login and file uploads locked down.
Performance tuning
OPcache and PHP-FPM configured properly, slow queries found and indexed, and Redis caching added where pages rebuild the same data on every request.
Symfony and Laravel
New work in modern frameworks, and the patterns that let old code adopt Composer, dependency injection and framework components a piece at a time.
WordPress and WooCommerce back ends
Custom plugins, REST endpoints, order workflows and HPOS-compatible WooCommerce extensions written to WordPress coding standards.
What we build
What we build with PHP.
Most PHP requests involve code nobody on the current team wrote. These are the ones we see most often from UK businesses.
Integrations for older systems
Xero, Stripe, GoCardless or CRM connections added to a legacy PHP app through queued jobs and logged webhooks, not cron scripts nobody monitors.
WooCommerce customisation
Checkout rules, shipping through Royal Mail, DPD or Evri, stock sync with your warehouse or ERP, and order data moved to HPOS.
Legacy app modernisation
A custom PHP app given Composer, a front controller, tests and then a framework, one area at a time — the business keeps using it throughout.
Security remediation
Pen-test findings fixed and re-tested, outdated libraries replaced, secrets moved out of the codebase and admin areas properly protected.
Moves to modern hosting
Off shared hosting or an old server onto containers or managed cloud, with NGINX and PHP-FPM, automated deploys and backups that have been test-restored.
APIs for newer front ends
A clean REST API added to an existing PHP system, so a new React or Vue front end or a mobile app can use it without a rewrite.

Pricing
PHP development pricing.
Start with discovery, move to a fixed-price build, or run a dedicated team for a longer roadmap.
PHP discovery sprint
From £2,000
Architecture, roadmap, cost planning, and project-risk validation
- A short strategy sprint covering technical scope, user flows, delivery plan, and budget range.
Managed PHP development project
Fixed quote
MVPs, rebuilds, SaaS platforms, dashboards, portals, and business-critical launches
- Product planning, UX, engineering, QA, deployment, and post-launch support under one delivery owner.
Dedicated PHP development team
From £9,500 per month
Longer roadmaps, multi-sprint delivery, and product teams that need extra senior capacity
- A stable engineering pod with weekly demos, sprint planning, code review, and transparent reporting.
Prices are in GBP. Every estimate is confirmed in writing after a discovery call — the figures above are where engagements start, not a quote.
How we deliver
How we deliver your PHP project.
Seven stages, the same on every project. The length of each one changes with the work; skipping one never saves time for long.
- 01
Product and technical discovery
We map your PHP product goals, users, integrations, compliance needs, timeline, and commercial priorities before planning the build.
Goals, users and constraints agreed
- 02
Architecture and delivery plan
You get a practical PHP roadmap with milestones, team shape, risks, estimates, and the first release path.
Roadmap, team and estimate
- 03
Design, build, and QA
Our team ships the PHP product in controlled sprints with code review, testing, demos, and visible progress every week.
Tested software every sprint
- 04
Launch and improvement
We handle deployment, analytics, monitoring, handover, and post-launch iterations so your PHP platform keeps improving.
Live, monitored and documented
Why Techsleight
What working with us is actually like.
No inflated numbers — just how we run projects, and what you can hold us to.
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.

Questions we get asked.
Straight answers on scope, cost, timelines and how we work. If yours is not here, ask us directly.
What does a PHP development company do?
A PHP development company plans, designs, builds, tests, deploys, and supports PHP software. At Techsleight Labs, that can include discovery, architecture, UI/UX, API integration, QA, cloud deployment, analytics, and post-launch roadmap support.
Do you work with companies in the United Kingdom?
Yes. This PHP development company page is focused on United Kingdom businesses. We support UK collaboration with clear written updates, weekly demos, and planned handoff points so distributed teams can move quickly.
How much does PHP development cost?
PHP development pricing depends on scope, integrations, user roles, design depth, compliance needs, and launch timeline. Discovery sprints start from £2,000, dedicated teams start from £9,500/month, and managed projects are quoted after scope validation.
Can you build a complete PHP product, not just provide developers?
Yes. You can use Techsleight Labs as a full PHP development company for strategy, design, engineering, QA, deployment, and support. You can also start with a small discovery sprint before committing to the full build.
Can you improve an existing PHP application?
Yes. We often join existing PHP products to fix performance, improve architecture, add features, stabilise releases, modernise UI, or prepare the system for scale. We begin with a focused audit so the first sprint is practical.
Who owns the code and product IP?
You own the code, documentation, product IP, design assets, and infrastructure setup created for your project. We can sign an NDA before discovery and work inside your repositories, cloud accounts, and project tools.
How fast can a PHP development project start?
Discovery can usually begin within a few working days of the first call, and most projects start within 5–7 working days of sign-off. Larger builds usually need a short planning sprint to confirm scope, architecture, milestones, risks, and the right team before full development begins.
Do you provide post-launch PHP support?
Yes. After launch, we can continue with monitoring, bug fixes, performance improvements, security updates, roadmap features, analytics, and handover support. Many clients keep a monthly retainer after the main release.
