Web development in London

You run a regulated business in a crowded market. Your web application has to work under load, integrate cleanly with what you already use, and pass compliance before launch. We build that.

Working in London

Web development for London businesses

Hubb Group is a digital agency and software company. Our studio is in Dubai and we work with UK clients remotely, on UK hours, with a named lead on every project. Contracts and invoices are issued by our UAE company, in pounds.

We measure uptime, response times at the 95th percentile, error rates, and deployment frequency. You get dashboards you can read yourself. We test under your real traffic patterns before handover. We document everything so your team owns the application long after we leave.

Every project is a fixed quote with a clear timeline and clear milestones. You own the work and the accounts outright when we're done — no lock-in, and nothing you can't take with you.

Applications that scale without breaking

London businesses process millions of transactions daily. Your application has to handle peak load without slowdown, without data loss, without dropping users mid-transaction. We architect for volume from the start—not as an afterthought. That means choosing the right database, the right queue systems, the right deployment strategy. We test under realistic load before you go live.

Downtime costs you. A portal that stutters during business hours costs your team productivity and your customers confidence. We build applications that stay up. We document the architecture so your own team can maintain it. We hand over runbooks, not mysteries.

Integration with systems you already depend on

You use ERPs, CRMs, payment gateways, legacy databases. Your new application sits in the middle. We map those integrations before we build anything, so the application speaks to your infrastructure cleanly. No middleware that creates more problems than it solves. No data that lives in two places and disagrees with itself.

We write the integration tests. We document the endpoints and the error states. We make sure your team can troubleshoot without calling us. If something breaks, you know what to look at and why.

Compliance and procurement checkpoints

London buyers ask about data location, security sign-off, and support cover before they sign. We build with those questions answered. Your data stays where regulation requires it. We document security decisions and controls. We agree support hours upfront. We don't discover these things at procurement review.

We know your legal team will read the handover documentation. We know your IT will need to patch and upgrade the application years from now. We build for that reality, not for the first demo.

What you measure and what we measure

Conversion matters in London because the shortlist is crowded. If your application is slow or unreliable, users leave. We measure response times at the 95th percentile, not the average. We measure error rates and recovery times. We track your actual infrastructure costs so you know what scale costs you.

We run load tests before handover using your real traffic patterns. We provide dashboards you can read yourself. We agree what 'working well' means before we build, not after. That's how you know whether we delivered.

What you get

Everything we deliver includes

Fixed prices

A clear quote and timeline up front — no open-ended retainers, no surprises.

A named lead

One person who knows the project, on UK hours, not a ticket queue.

Documented handover

Source, environment notes and runbook, so another developer can pick it up cold.

Integrations that hold

Built against the systems you already run, with sensible behaviour when they fail.

Tested under load

Performance budgets agreed up front and checked before launch, not after.

Your repository

Code in your organisation from the first commit, not transferred at the end.

Questions

Web development in London — common questions

How do you handle compliance and audit trails?

We build logging and audit controls into the application from day one. We document access controls and data residency decisions. We make sure your compliance team has what they need to sign off before go-live.

What happens after launch? Do we get support?

Yes. We agree support hours and response times upfront. We hand over runbooks and documentation so your team can troubleshoot. We patch security issues and dependencies. The scope depends on your contract.

We're on the shortlist with three other agencies. What makes you different?

Most agencies show you a demo and a proposal. We spend time understanding your existing systems and compliance obligations before we quote. We test under your real load. We deliver documentation that survives handover.

How long does a custom application take to build?

That depends on scope, not on a formula. We break the work into phases so you see progress. We agree on milestones upfront. We don't build everything before you see anything.

Do you integrate with our existing ERP or CRM?

Yes. We map integrations early and test them thoroughly. We use your real API documentation and credentials during development. We handle error states and data reconciliation.

What if we need to migrate data from an old system?

Data migration sits outside the application build, but we work with your team to understand the mapping. We make sure the application can ingest the migrated data cleanly and we test it thoroughly.
