Energy Software Development in London
Systems for London energy suppliers and service companies, where the industry's own data flows set the shape of the software. Registrations, meter readings and settlement move through defined market messages on defined timescales, and a platform that treats those as an integration afterthought will spend its life reconciling positions it cannot explain.
Why this comes up
The problem
Billing, metering and the market position are maintained separately, and the three disagree in ways nobody can reconstruct.
What you get
What we deliver
- Market data flows handled as a core function rather than a peripheral feed
- Readings held with their source and status, since not all readings are equal
- Billing derived from the settled position, not from a parallel calculation
- Vulnerable customers identified and their needs recorded for the register
- Prepayment and credit journeys built as genuinely different experiences
- Switching handled to the industry timetable, including objections

Energy Software Development in London — common questions
- Why do readings need status?
- Because an estimate, a customer-submitted figure and a validated meter read are different things with different reliability, and billing on the wrong one produces the corrections that generate complaints. Keeping the provenance is what lets you explain a bill afterwards.
- What is the register for vulnerable customers?
- A record of customers needing extra support — medical dependence on supply, communication needs, safety concerns — used to prioritise them during interruptions and to shape contact. It only works if the data is maintained rather than captured once and left.
- Why keep prepayment separate?
- Because the customer experience is structurally different: balance, top-up, emergency credit and self-disconnection have no equivalent in credit billing. Systems that model prepayment as credit with a different payment method handle the hard cases badly.
- Can we build this on a generic billing platform?
- Partly. The invoicing is ordinary; the industry interfaces, the settlement position and the regulated timetables are not, and those are where the effort actually is. Assess a platform on how it handles market flows rather than on how it renders an invoice.
- 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.
