Salesforce Development in London
Apex and Lightning development for London Salesforce orgs, where the platform enforces its multi-tenancy by terminating your transaction. Governor limits cap queries, records processed and processing time per transaction — so bulk-safe code is not a quality standard here, it is the difference between working and failing the first time a data load runs.
Why this comes up
The problem
The trigger works fine when a user saves one record and fails immediately when an integration sends two hundred.
What you get
What we deliver
- Code written to operate on collections rather than one record at a time
- Queries and updates kept out of loops, where limits are exhausted fastest
- One trigger per object with logic delegated to a handler class
- Asynchronous processing where the work genuinely exceeds a single transaction
- Test coverage that exercises bulk cases, not just the happy single record
- Configuration preferred wherever it would meet the requirement without code

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.

Salesforce Development in London — common questions
- What actually happens when a limit is hit?
- The transaction is terminated and rolled back. There is no degraded mode — the save fails, the integration errors, the user sees an exception. That makes bulk-safety a functional requirement rather than an optimisation to revisit later.
- Why one trigger per object?
- Because the order in which multiple triggers on the same object run is not guaranteed. A single trigger delegating to a handler makes execution order explicit and debuggable, which matters enormously once several teams have added behaviour over the years.
- Is test coverage just a deployment requirement?
- The percentage is, but the tests are worth writing properly. Coverage achieved by asserting nothing passes deployment and catches nothing, and the failures that matter here — bulk behaviour, limits, sharing — only appear in tests deliberately written for them.
- When should we write code at all?
- When configuration genuinely cannot do it. Flow has absorbed a great deal of what once needed Apex, and code carries a permanent cost — tests, deployments, three upgrades a year. The right question is what remains after the platform's own tools are exhausted.
- 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.
