PHP 5 and 7 to PHP 8.x
Removed functions, stricter typing and deprecation notices fixed systematically, with Rector for the mechanical changes and PHPStan to catch the rest.
Hire PHP developers · UK
Upgrade, secure and speed up the PHP systems your business runs on, with developers equally at home in decade-old code and modern PHP 8.
PHP expertise
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.
Removed functions, stricter typing and deprecation notices fixed systematically, with Rector for the mechanical changes and PHPStan to catch the rest.
Characterisation tests that pin down what the code does now, so it can be refactored and upgraded without changing behaviour by accident.
SQL built from strings replaced with prepared statements, output escaped, weak password hashes upgraded at login and file uploads locked down.
OPcache and PHP-FPM configured properly, slow queries found and indexed, and Redis caching added where pages rebuild the same data on every request.
New work in modern frameworks, and the patterns that let old code adopt Composer, dependency injection and framework components a piece at a time.
Custom plugins, REST endpoints, order workflows and HPOS-compatible WooCommerce extensions written to WordPress coding standards.
What they build
Most PHP requests involve code nobody on the current team wrote. These are the ones we see most often from UK businesses.
Xero, Stripe, GoCardless or CRM connections added to a legacy PHP app through queued jobs and logged webhooks, not cron scripts nobody monitors.
Checkout rules, shipping through Royal Mail, DPD or Evri, stock sync with your warehouse or ERP, and order data moved to HPOS.
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.
Pen-test findings fixed and re-tested, outdated libraries replaced, secrets moved out of the codebase and admin areas properly protected.
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.
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.

Sets the PHP architecture, reviews the team's code and plans migrations, upgrades and scaling work.
A PHP developer with backend, QA or design support, coordinated by one delivery owner for larger scopes.
Engagement models
Pay by the hour for bursts of work, reserve a dedicated developer for your roadmap, or hand us the whole project.

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 hiring works
The goal is not just to introduce a PHP developer — it is to make the first week useful and the work visible from then on.
We review your PHP goals, current stack, deadlines, risks, and success metrics before suggesting an engagement model.
Role and success criteria agreed
You get a clear PHP developer profile, relevant experience, availability, and estimated weekly capacity.
Developer profiles to review
We agree priorities, access, communication rhythm, delivery milestones, and code review expectations. Most engagements start within 5–7 working days of sign-off.
Access, rituals and first tickets
Every week you see working PHP progress, blockers, next steps, and measurable delivery against the plan.
Visible progress every week
Why Techsleight
What you can hold us to — and what happens if something is not working.
You see profiles and talk to the PHP developer before anything starts, and nobody joins your team without your say-so.

Your repositories, tickets, stand-ups and review rules. Daily written updates and a weekly demo keep the work visible.
Hourly, dedicated or project-based, with short notice periods. Scale up for a launch and back down after it.
Code, IP and documentation belong to you from day one. NDA before any detailed conversation, if you need one.
UK business hours, GBP pricing and a contract with a UK company. Our engineers are based in the UK and India.
Backend, QA, DevOps and design colleagues are there when the PHP work needs them — without you hiring for each role.
Relevant work
We do not have a published PHP case study yet — these show the kind of product work our engineers join.
All case studiesUniversity management system replacing spreadsheet enrolment and timetabling.

FAQs
Straight answers on scope, cost, timelines and how we work. If yours is not here, ask us directly.
More urgent than it may look. PHP 7.4 reached end of life on 28 November 2022, so vulnerabilities found since then go unfixed, and every PHP 8 release has its own published end-of-life date. Unsupported versions are a common finding in pen tests and security questionnaires, and Cyber Essentials expects software to be supported. We aim for the newest version your framework, plugins and hosting all support.
Usually modernise. A rewrite has to rediscover every business rule the old code quietly handles, and the business waits months for parity. We add tests around current behaviour, upgrade PHP, introduce Composer and a framework piece by piece, and fix the worst areas first. A rewrite makes sense when the old system blocks something the business needs and cannot be untangled.
Either can work. Symfony’s components can be introduced into old code one at a time — routing, dependency injection, forms — which suits a gradual modernisation of a large bespoke system. Laravel is quicker to be productive in and ships first-party tools for queues, authentication and billing, which suits teams rebuilding areas outright. We look at the codebase and your team before recommending either.
Yes, on the code side: custom plugins, WooCommerce extensions, REST endpoints, performance and security fixes, and upgrades of old themes and plugins. For content-led sites and theme builds, our WordPress developers are usually the better fit.
PHP developer rates at Techsleight Labs start from £23/hour for flexible work and from £3,300/month for dedicated monthly capacity. Fixed-price PHP projects are quoted after discovery, once scope, integrations, risks, and timeline are clear.
Most PHP engagements start within 5–7 working days of sign-off, and urgent work can sometimes start within 48–72 hours. For larger projects, we first confirm scope, architecture, milestones, and the right senior engineer fit before kickoff. We support UK teams with written updates, planned demos, and timezone-aware handover.
Yes. You can hire a single PHP developer, add a small pod with QA and DevOps, or ask us to manage the complete project. We match the model to your current team, delivery pressure, and budget.
Yes. Our hiring pages are built around senior production engineers, not junior bench resources. Every developer is reviewed for commercial project experience, communication quality, code quality, testing habits, and ability to work inside existing teams.
Yes. We often join existing PHP projects to fix performance, unblock releases, add features, improve test coverage, or modernise architecture. We start with a codebase review so the first sprint is practical rather than theoretical.
Tell us early. We will look at the cause with you — the brief, the onboarding or the match — and agree the next step together, such as more technical oversight, a different engagement model, or ending the engagement on the notice terms in your contract. The goal is a useful working relationship, not lock-in.
