Load Testing in London
Testing what London organisations' systems do under real load, which means testing journeys rather than endpoints. Hitting one URL a thousand times a second proves that URL is fast; it says nothing about the checkout, where each step queries a different service and the slow one only appears when several run together.
Why this comes up
The problem
The homepage was load tested successfully and the site fell over during a promotion at a fifth of that traffic.
What you get
What we deliver
- Scenarios modelled on real user journeys, in the proportions they actually occur
- Think time included, since users pause and that changes the concurrency profile
- Data varied realistically, because caching hides problems when every request is identical
- The breaking point found deliberately, not just the target load confirmed
- Behaviour past that point observed — whether it degrades gracefully or collapses
- Bottlenecks identified in the results rather than left as a pass or fail figure

Thirty minutes, no charge, no sales script. You leave with a written summary of what load testing would actually involve — whether or not you use us.
Working in London
London
London clients usually come to us because they want senior people actually on their project rather than a large agency's B team, and because Midlands rates buy considerably more delivery per pound.
Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates.

Load Testing in London — common questions
- Why test journeys rather than endpoints?
- Because failures come from interaction. A checkout touches inventory, pricing, payment and email, and the constraint is usually one of those under concurrent load — a test hitting each in isolation passes while the combination fails at a fraction of the volume.
- What difference does realistic data make?
- Frequently the whole result. Requesting the same product a million times populates every cache and produces excellent figures, whereas real traffic spreads across thousands of products and hits the database — which is the behaviour that matters.
- Why find the breaking point?
- Because you need to know the margin. Confirming the system handles the expected peak tells you nothing about whether you are at eighty per cent of capacity or eight, and the first of those is a situation worth knowing about before the promotion.
- What matters about how it fails?
- Whether recovery is possible. A system that slows down, sheds load and returns to normal is manageable; one that exhausts connections, cascades and requires a restart turns a busy hour into an outage — and the difference is usually a small amount of deliberate design.
- Do you work with businesses across Greater London?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of London businesses do you usually work with?
- Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
- Do you cover the areas around London?
- Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
