We built the platform that now runs Britain's largest energy supplier. The migration is done. From today we're the product company taking it to every supplier — everywhere.
British Gas completed migrating all residential customers onto Ignition in 2026 — the multi-year, make-or-break delivery is done, and NPS is materially higher on-platform. The make-it-work era is over; the make-it-a-product era begins.
The shift Grace Rothery (now Chief of Staff) set out for 2026 — making ENSEK genuinely product-led in how it builds and delivers, with OKR-driven execution. Each pillar is anchored to a real, observable signal.
One opinionated, roadmapped platform that ships product — replacing bespoke, services-heavy delivery. A new product org, built on purpose.
British Gas is the proof, not the ceiling. Take Ignition, Gross-Margin Reporting and Flex to the wider supplier market as productised offers.
Gross-Margin Reporting as the flagship wedge — sold as a data product in its own right. Meter-level, Working-Day-1, exceptions valued and ranked.
Unify Ignition (run), Flex (flexibility/VPP) and Zoa (consumer) into one intelligent orchestration layer for the net-zero grid.
From a UK-deep platform to a multi-geography one — Europe first (Benelux foothold), then beyond, on the same real-time spine.
It's the same thesis since day one (founded 2010): bad industry data is the enemy. Ignition is the cure, now packaged as product. Margin truth wasn't an add-on — it was the starting point.
The relaunch sharpens what's already there — it doesn't throw it away. The wordmark stays; the story grows up from “utility software vendor” to “the operating system for energy.”
Radical financial accuracy. Numbers you can stand behind, to the meter, on day one. The DNA, made the headline.
Human outcomes over throughput. The customer's experience is the scoreboard — NPS, not just uptime.
We ship product, not projects. Opinionated, reusable, roadmapped — built once, run everywhere.
Event-driven by default. No batch delays, no month-end black holes — the platform knows now.
Data quality, auditability and compliance baked in. The “rotten apple” of bad data — solved at the root.
We earned it the hard way — the UK's biggest migration. Now we innovate from a position of proof.
Navy = the trustworthy backbone. Orange = the spark of orchestration — used for the moment energy connects. Held disciplined: one accent, lots of air.
474 employees (FY2024 audited accounts, up 32% from 360) across 2 continents · ISO/IEC 27001 (per ENSEK) · MHHS-ready · Centrica-owned via ENSEK Holdings ← GB Gas Holdings ← Centrica (from 20 Sep 2024) · NPS materially higher on Ignition.
Audited FY2024 accounts (Companies House, via the CH API + OCR of the scanned filing): turnover £50.7m; ~50% professional services (project) revenue with recurring SaaS down year-on-year — the hard financial case for the product-led pivot; and the majority of revenue from a single large customer (Centrica / British Gas), with the accounts themselves stating ENSEK is "building a convertible pipeline of large opportunities to provide dilution" — the financial case for commercialising beyond British Gas.
The product-led pivot, declared now BG is done — refreshed identity, “Energy Orchestration Platform” arrival, new website.
