Custom PHP and MySQL application development in London

When an off-the-shelf plugin does not fit the business, I build the thing that does — booking systems, client portals, quote calculators, admin dashboards, and integrations with whatever API you already depend on. For London businesses, quoted in GBP from $200, typically live in 10 days.

Why this matters for United Kingdom specifically

UK local search is the most saturated in the English-speaking world, so a merely competent site does not win the job — the quote form does. Every UK build I ship is specified around the enquiry step first and the homepage second.

What actually ships when a London project goes live

A handover for a London client is not a link and a login. It is the repository, the hosting account in your name, the domain registered to you, the payment provider account under your business, and a written record of every credential as it was created rather than dumped in one email at the end.

The test I apply is uncomfortable but correct: if I disappeared tomorrow, could another developer pick this up on Monday without calling me? If the answer is no, the handover is not finished. That standard is why the documentation takes a day I do not bill separately — it is part of the build, not an upsell.

Education and training providers in London

Course pages are the whole site. Each needs the outcome, the duration, the price, the prerequisites and the next start date visible without scrolling — and each needs to be its own indexable URL, because people search for the course, never for a training provider they have not heard of.

The recurring failure is a single "Courses" page listing twenty courses. It ranks for nothing because it is specifically about nothing. Twenty pages, each genuinely about one course, is more work and is the difference between a site that recruits and a brochure that sits there.

A redesign that quietly deleted the rankings

The classic disaster: a new site launches, looks far better, and organic enquiries fall off a cliff within a fortnight. The cause is almost always identical — the URLs changed and nothing was redirected, so every page that had accumulated years of authority now returns a 404.

Preventing it is a redirect map built before launch: every old URL to its closest new equivalent with a 301, and anything without an equivalent pointed at the nearest relevant page rather than the homepage. If your London site is being redesigned by anyone, ask to see that map. If it does not exist, that is the entire risk in one document.

What I am not claiming about London

Custom PHP and MySQL application development in London — common questions

Do you actually work with businesses in London?
Yes, remotely. I work with British clients from Islamabad, quoting in GBP and invoicing in GBP. I have no office, address or phone number in London and will not pretend otherwise. If your project needs someone physically present, hire locally — I will say so in the first reply rather than after a deposit.
Can you migrate my London site without losing rankings?
Yes, and the redirect map is the whole job. Every existing URL is mapped to its new equivalent with a 301 before launch, and anything with no equivalent goes to the closest relevant page rather than the homepage. Sites lose rankings in migration because that mapping was skipped, not because migration is inherently risky.
Do you build on WordPress or something custom?
Whichever the project justifies. WordPress when you need to edit content constantly and want a familiar admin. A static build when speed and security matter more than a plugin ecosystem. Custom PHP and MySQL when the logic is genuinely yours. The choice is explained in the quote with its trade-offs, not presented as a foregone conclusion.
What happens if I am not happy with the result?
Work is delivered in milestones against a written scope, and you review each one on a staging URL before it is paid for. If the delivered milestone does not match the scope, it gets corrected before anything moves forward. That structure exists so disagreement is resolved at the stage it happens rather than at the end when it is expensive.
How do you handle our customers' data under UK GDPR?
Your customer data is governed by UK GDPR and the Data Protection Act 2018, and sending it to a developer in Pakistan is a restricted transfer. That is resolved by a pre-signed DPA with a completed UK International Data Transfer Addendum, published on this site and pre-signed before you send an enquiry — not drafted after you ask about it.
Who owns the website when it is finished?
You do, completely. The domain is registered in your name, hosting sits in your account, the code lives in a repository you control, and any payment provider account is opened in your business name. Credentials are handed to you as they are created rather than at the end, so you are never locked out of your own site.
What currency will I be invoiced in?
GBP. Quotes, milestones and the final invoice are all written in GBP so you are never comparing a converted figure against a local supplier's. Regarding tax: VAT at 20% once you are registered — my invoices are outside the scope of UK VAT and you account for them under the reverse charge.
