CodeIgniter Development in Guildford, Surrey
Lean CodeIgniter web apps and APIs for Guildford and Surrey businesses, built fast where a heavier framework would be overkill. Plus expert support, modernisation and rescue of the CI3 and CI4 applications you already depend on. Built properly, maintained long-term, delivered by a UK team you actually speak to.
Trusted by:
CodeIgniter is for lean, fast builds, and for keeping what you already have alive.
CodeIgniter is a lightweight PHP framework. Its whole design philosophy is to stay out of the way: a small footprint, minimal configuration, and an easy learning curve, which means a focused application gets built and shipped quickly without a lot of ceremony. Where a larger framework wants you to adopt its full structure before you write a line of useful code, CodeIgniter lets you build the thing you actually need and not much else. For a lot of practical business software, that is exactly the right trade.
There is also a second, less talked-about reason CodeIgniter matters: an enormous number of working business applications were built on it over the past decade and a half, and many are still running today. CodeIgniter 3 in particular sits underneath countless internal tools, portals and back-office systems that companies in Guildford and across Surrey still rely on, often after the original developer has long gone. Supporting, securing, modernising and where necessary rescuing those applications is a large part of what we do. The framework that is fast to build with is also one that rewards a developer who actually understands it when something needs fixing.
Lean web apps, built fast
Focused applications with a clear, modest scope where a quick, economical build matters more than a heavyweight architecture. CodeIgniter's small footprint and minimal configuration mean less time spent on scaffolding and more on the feature you actually need.
Legacy CI3 support and rescue
The big one. Existing CodeIgniter 3 applications that a business still depends on, often unmaintained since the original developer left. We audit, stabilise, secure, fix and extend them, and give you an honest plan for their future rather than a knee-jerk rebuild.
Maintenance and modernisation
Keeping a CodeIgniter application healthy: PHP version upgrades, dependency updates, security patching, performance tuning, and incremental modernisation so that staying supported is a managed routine rather than a problem that quietly builds up.
Simple to mid-complexity APIs
REST APIs and endpoints where the requirement is clear and the scope is contained, serving a front-end, a mobile app, or another system. CodeIgniter gets a clean, workable API up quickly when you do not need the full weight of a larger framework.
Internal tools and admin utilities
Back-office utilities, admin panels, data-entry tools, and the small operational applications that quietly keep a business moving. Practical software that needs to work reliably and be cheap to change, without being over-engineered.
CI3 to CI4 migrations
CodeIgniter 4 is a substantial rewrite of the framework, not a drop-in upgrade. Where it is the right move, we plan and carry out the migration carefully, preserving the business logic that often lives only in the old code and keeping the application running throughout.
Laravel vs CodeIgniter vs WordPress
We build in Laravel, CodeIgniter, and WordPress. We are not going to recommend one over the others just to win a project. The right framework depends on the problem, and picking the wrong one is one of the most expensive mistakes a project can make. Here is an honest comparison of when each is the right choice, and where CodeIgniter genuinely shines.
| Situation | Laravel | CodeIgniter | WordPress |
|---|---|---|---|
| Lean web app or tool, fast turnaround, modest scope | Can be overkill | ✓ Best fit | Depends on content |
| Supporting an existing CodeIgniter (CI3/CI4) app | Not applicable | ✓ Best fit | Not applicable |
| Simple to mid-complexity REST API | Workable, heavier | ✓ Best fit | Not suited |
| Complex application with heavy business logic | ✓ Best fit | Can outgrow it | Not suited |
| Content-led site with editorial workflow | Possible but heavy | Not suited | ✓ Best fit |
| Multi-tenant SaaS or large structured team | ✓ Best fit | Workable, less so | Hard to govern |
| Heavy background processing and scheduled jobs | ✓ Best fit | Manual effort | Not suited |
| Small footprint, minimal hosting, fast to ship | Heavier stack | ✓ Best fit | Plugin-dependent |
CodeIgniter is the best fit when you want a lean build delivered quickly, or when you need someone to look after an existing CodeIgniter application properly. When the requirement is genuinely complex, Laravel is usually the better long-term home, and for content-led sites WordPress almost always is. If you are not sure which applies, describe the problem and we will tell you what we would reach for and why, even if the honest answer is that you do not need us at all.
How we approach a CodeIgniter project
Whether we are building a lean new application or taking over one that already exists, the framework is the easy part. The value is in the thinking: understanding what the software really has to do, and, when it is an inherited codebase, understanding what you have actually got before touching anything. Here is what we pay attention to, and the stages a piece of CodeIgniter work moves through.
Understanding the real requirement
Most briefs describe a solution someone has already half-designed. We dig into the underlying problem first, because the right approach, and whether CodeIgniter is even the right tool, follows from what the business actually needs.
An honest code audit first
For existing applications we start with a proper audit: the CodeIgniter version, the PHP version, the state of the code, the security exposure, and the technical debt. You get a straight assessment of what you have before any work is agreed.
Security and supported versions
CodeIgniter 3 reached end of life, and many legacy apps run on unsupported PHP. Getting onto supported foundations and closing security gaps is usually the first priority on inherited work, not an afterthought.
Lean by design, not by accident
CodeIgniter rewards restraint. On new builds we keep the application focused and the footprint small, so it stays fast, cheap to host, and easy to change, rather than quietly accreting weight it never needed.
Maintainable by anyone competent
We write readable, conventional CodeIgniter so you are never locked into a single developer, exactly the situation many inherited applications were left in. If you bring the work in-house later, the code makes sense to whoever picks it up.
Integrations mapped early
Most operational software has to talk to something else: a payment provider, a finance system, another internal tool, a third-party API. We identify every integration up front so none of them become a nasty surprise late in the work.
From first conversation to long-term maintenance
We run CodeIgniter work in clear stages so you always know where things stand, what is being decided, and what comes next. Because you deal directly with Rob and Jason rather than an account manager, there is no layer of translation between what you ask for and what gets built or fixed. This is the same process whether you are in Guildford, London, or anywhere else in the UK.
- Discovery, audit and scopingFor a new build we get to the bottom of what the application needs to do and who uses it. For existing software we audit the codebase first and report honestly on its state. The output is a clear scope and a fixed-price proposal based on what we actually find.
- Stabilise or architectFor inherited apps, the early priority is usually getting onto supported PHP, closing security gaps, and steadying the parts the business depends on. For new builds, this is where we design a focused, lean structure deliberately rather than by accident.
- Build or improve in working incrementsWe work against a staging environment you can access throughout, so you see real progress rather than waiting for a single big reveal. Feedback happens while it is still cheap to act on.
- Testing and quality assuranceThorough testing of the workflows your users actually follow, plus automated tests around the logic that matters most. We test the awkward edge cases, not just the happy path that always demos well.
- Deployment and go-liveA controlled deployment to production with a clear plan, sensible rollback, and particular care where a live application that a business already depends on is being changed. Going live should be an event you have rehearsed, not a leap of faith.
- Handover and ongoing supportDocumentation, access, and a straightforward handover, followed by whatever ongoing arrangement suits you, from occasional changes to a regular support retainer. We keep CodeIgniter applications updated, secure and supported for the long term.
We have run and maintained our own PHP software since 2011.
CoreCRM, our own CRM product, has been in continuous production use since 2011. It is direct evidence that we build software designed to be maintained and depended upon for well over a decade, through multiple PHP and framework versions, not just for the length of a single project. That long-term, maintenance-minded discipline is exactly what an existing CodeIgniter application needs from whoever looks after it, and it is the same care we bring to inherited client codebases.
A Kent team trusted with national operational work
Telegraph Media Group, Hearst Communications, CDS Global, AX Paris, Motel Rocks
These are not the typical clients of a regional development agency. They are the kind of businesses that usually work with large London firms. They work with us because the technical depth is there and the overhead is not, and because they get the founders directly rather than a managed account. Distance has never been the issue: most of our work has been delivered remotely for years.
PHP is the common thread across that work, and our practical, maintenance-minded approach is exactly what a lean CodeIgniter build or an inherited CodeIgniter application needs. When a system has to keep working reliably for years with a team that may have changed entirely, what matters is a developer who writes code the next person can understand, and who is still around to support it.

Working with Guildford and Surrey businesses
Guildford sits at the heart of one of the strongest local economies in the country. It is a recognised technology centre, with the University of Surrey and the Surrey Research Park anchoring a deep cluster of software, gaming, satellite, telecoms and life-sciences companies, alongside a dense professional-services and corporate base. That mix produces exactly the kind of businesses that run on practical operational software: internal tools, customer portals, booking and admin systems, lightweight APIs, and bespoke applications that off-the-shelf products never quite fit.
A lot of that software was built years ago, frequently on CodeIgniter, and is now quietly load-bearing while the people who originally built it have moved on. That is precisely the work we are well suited to: building lean new tools quickly, and looking after the existing applications a business cannot afford to have fail. We are not local to Guildford, and we are not going to pretend otherwise; what we offer instead is a genuinely senior UK team, working entirely in-house with no offshore arm, available to you directly rather than through layers of account management.
In practice that changes nothing about the quality of the work. Most of our projects, including for national clients, are delivered remotely with regular video calls and a shared staging environment you can see progress on. Guildford is a straightforward trip from Gravesend around the M25, so we come over for a kick-off workshop or a key milestone when being in the room genuinely helps, and otherwise we keep the overhead, and your costs, sensibly low.
How to choose a CodeIgniter developer in Guildford
Whether you end up working with us, a local Guildford agency, or a freelancer, these are the questions worth asking before you commit, especially if someone else is going to be trusted with an application your business already relies on. The answers tell you a lot about what you are actually buying.
Who actually writes the code?
Some agencies pitch with senior people and deliver via juniors or offshore teams you never meet, the very situation that leaves so many CodeIgniter apps orphaned. Ask directly who will work on your application and who you call when something breaks. At Dev Partners it is the founders and an in-house UK team, with no offshore.
Can they support legacy CodeIgniter, not just build new?
Plenty of developers can spin up a fresh app. Far fewer are willing to dig into someone else's CI3 codebase, understand it, and improve it safely. Ask about their experience taking over and maintaining existing applications, because that is where the real skill shows.
Is the framework choice honest?
A developer who recommends the same tool for everything is selling, not advising. The right partner will tell you when Laravel is a better long-term home for a complex app, or when WordPress fits a content site, rather than defaulting to whatever they prefer to build.
How do they handle handover?
You should never be locked in by code only one person understands, which is exactly how many legacy CodeIgniter apps ended up stranded. Ask about documentation, coding standards, and what happens if you take the work in-house. Conventional, readable code is the answer.
What does ongoing support look like?
An application is not finished at launch, and a legacy one is never finished at all. Ask how they keep PHP and CodeIgniter versions current, how they handle security updates, and what a support or retainer arrangement actually costs. Vague answers here become expensive later.
How do they scope and price?
A low headline figure that grows through change requests is not a bargain, and an open-ended hourly rate on a legacy rescue can run away fast. Ask how they scope, whether you get a fixed price, and what is and is not included. We audit first and quote a fixed price based on what we actually find.
What our clients say
20 clients. A few of their words.
A well-rounded team, ensuring a full suite of expertise & resource is always available. CDS Global have seen the successful completion of major projects over the years where Dev Partners' ability to grasp the underlying business needs to provide a future-proof solution has been invaluable.
We have worked with Jason & his team to develop our Shopify store, and the experience was outstanding from start to finish. The design is clean, modern, and perfectly aligned with our brand identity, while the build is fast, responsive, and easy to manage on the backend. They clearly understood our vision and delivered a store we're genuinely proud of. Highly recommend to any brand looking for a top-quality Shopify partner.
After ongoing issues and delays with our previous developers, we brought in Rob & Jason at Dev Partners to take over all our websites and bespoke software. What a breath of fresh air, fully focused, excellent pre-launch designs and clear communication throughout. Highly recommended.
BPC Energy Ltd turned to Dev Partners for a complete turnkey solution, and they exceeded our expectations. The team handled everything from project management to development and support with real care and attention. They understood what we were aiming for, stayed on top of every detail, and always delivered on schedule with excellent quality.
Working with Dev Partners to redesign and modernise our WMS system: the whole process has been thoroughly professional from the outset and a delight to work with. Cannot recommend enough.
Great agency. Have used Dev Partners for several years and they have built 20+ sites for us, in addition to taking on our legacy websites, upgrading and maintaining. Easy to work with and some great practical ideas to improve our digital offerings.
Jones Hire have been working with Dev Partners on several projects, which have been very successful. They linked our catering database to a new improved website so clients can easily place and update orders, created a custom warehouse picking app to fulfil all our challenging requirements, and are currently developing a custom transport app to streamline our loading and delivery process.
We have been trying to reinvent our website for over 5 years, trying to make it convert and failing each time. Spoke to Rob at Dev Partners, the team helped create our new site and the improvement was instant.
We have been working with Rob and the team for about 10 years now. Dev Partners helped us build a completely bespoke CRM from scratch which manages our daily business and is always well maintained. We have been able to use the system and roll it out in our new franchise branches.
We collaborated with Dev Partners on the front end of a fairly complex telemarketing platform. Rob and Jason took the time to properly understand the moving parts, asked the right questions, and delivered a clean, intuitive interface that's made the system far easier for our team to use.
I have been working with the team at Dev Partners for the last 3 years and we have always been impressed with the speed in which they act on things for us, along with the honest open communication. The team are a valuable and vital part of our supply chain.
We've had a program for our business in the electronic security sector that Dev Partners developed and keep up to date. They've never let us down, always there when needed. Thanks Rob and the team.
Dev Partners have been working with us for just over 2 years. They have significantly upgraded and redesigned our existing web platforms, and always deliver a first class service.
Dev Partners helped us build an event website. The team were very knowledgeable, easy to work with and quick to deliver a high quality product.
Working with Dev Partners has been an exceptional experience. Their team is highly skilled, professional, and committed to delivering results. What truly sets them apart is their communication and transparency; we always felt informed, supported, and confident.
We've worked with Dev Partners a few times to support us on bespoke web build tasks. They're very easy to work with, approachable, and explain the detail in a way that's understandable. A great partner for technical issues at sensible prices.
Excellent customer service backed up with solid experience. As a media business we have had five websites built by Dev Partners. I would certainly recommend them.
Found Dev Partners and they were great, nothing too much trouble. They managed to help us with integrating our old existing system with Shopify.
I've worked with Rob and his team off and on for many years and have always found them to be professional, knowledgeable, and best of all, they listen to their clients and deliver what is required.
We have worked with Dev Partners for 7 years and can highly recommend them for their expertise and excellent customer service.
CodeIgniter development in Guildford: questions answered
The questions Guildford and Surrey businesses ask us most often about CodeIgniter projects, both new builds and existing applications.
Yes. Dev Partners is based in Gravesend, Kent, and we work with businesses across the whole of the UK, including Guildford and the wider Surrey region. CodeIgniter development is delivered remotely as standard, and the distance makes no difference to the quality of the work.
You deal directly with the founders, Rob and Jason, throughout the project. Guildford is a comfortable trip from Gravesend via the M25, so we travel over for a kick-off or key milestones when it genuinely adds value, and otherwise keep the overhead low.
CodeIgniter is a lightweight, fast PHP framework. It is our choice when a project needs to be built quickly and run lean: focused web apps, internal tools, simple APIs, and back-office utilities where the structure and overhead of a larger framework like Laravel would be more than the job requires.
It is also the framework a great many existing business applications were built on, which is why a large part of our CodeIgniter work is supporting, maintaining and modernising CI3 and CI4 systems that companies still rely on every day. For genuinely complex applications Laravel is often the better fit, and for content-led sites WordPress usually is. We will tell you honestly which one suits your project.
Lean web applications and internal tools built quickly, simple to mid-complexity REST APIs, back-office and admin utilities, and integrations between systems. Just as importantly, we support and modernise existing CodeIgniter applications: CI3 and CI4 codebases that need bug fixing, security updates, new features, performance work, or a careful migration onto supported foundations.
Guildford has a strong technology, professional services and life-sciences economy, and a lot of that sector runs on exactly this kind of practical operational software.
Yes, and it is one of the most common reasons businesses come to us. A great many applications were built on CodeIgniter 3 by a developer or agency that has since moved on, and the business still depends on the software.
We start with a proper code audit, give you an honest assessment of the quality, the version, and any technical debt, and then work to whatever scope makes sense, from keeping the lights on through to a planned modernisation or migration. We tell you what you are dealing with before committing to any work.
You have more options than you might think, and a full rebuild is rarely the first one we recommend. CodeIgniter 3 reached end of life, so the priorities are usually getting it onto a supported PHP version, closing any security gaps, and stabilising the parts the business depends on.
From there the choice is between continuing to maintain it, modernising it incrementally, migrating to CodeIgniter 4, or rebuilding on a more capable framework if the application has outgrown CodeIgniter. We assess honestly and recommend the option that protects your business for the least sensible spend, not the one that bills the most.
It depends on the work. A focused CodeIgniter app or API built from scratch is often quick and economical precisely because the framework is lean. Support and maintenance of an existing application can be arranged as ad-hoc work or a monthly retainer. A modernisation or migration is scoped after we audit the existing codebase, because the price depends entirely on what we find.
In every case we scope carefully and give you a fixed-price proposal based on what we actually find, rather than an estimate designed to win the work and adjust later.
Almost all of our project work is delivered remotely, and that has been true for years across our entire client base, including national names. The quality of a CodeIgniter application has nothing to do with where the developer is sitting when they write it.
We run regular video calls, share progress on a staging environment you can access, and stay reachable directly. Guildford is an easy trip from Gravesend around the M25; we travel over when a workshop or milestone genuinely benefits from being in the room, and otherwise keep the overhead, and your costs, low.
No. Dev Partners has been a 100% UK in-house team since we were founded in 2008. There is no offshore arm and no subcontracting of the build. The people who scope your project are the people who write the code and the people you can call when something needs attention.
For Guildford clients that means you get a genuinely senior UK team without the cost structure of a large London or regional agency, and without your application being passed to a team you never meet, which is how a lot of legacy CodeIgniter apps were orphaned in the first place.
Sometimes, but not automatically. If your CodeIgniter application is doing a focused job well, the honest answer is often to keep it on CodeIgniter and maintain it properly. Migration makes sense when the application has genuinely outgrown the framework: complex business logic, heavy background processing, a large team working on one codebase, or requirements that fight against CodeIgniter's lean design.
We will tell you which situation you are in rather than pushing a migration you do not need, and if a move is worthwhile we plan it carefully with parallel running and preservation of the business logic that often lives only in the old code.
CoreCRM is our own CRM product, in continuous production use since 2011. It matters because it is direct evidence that we build and maintain serious PHP software over the long term, not just for the length of a project, and that we keep applications running and supported through many years and multiple framework versions.
That same long-term, maintenance-minded approach is exactly what an existing CodeIgniter application needs from whoever looks after it.
