Craig Lewis is CEO and CTO of LDS Consultancy and one of its three founders. He works with CIOs and boards on cyber, identity, software delivery and the energy cost of modern infrastructure.
Energy Optimisation
A century ago, engineers made electricity so easy we forgot it was there. Now heat pumps, batteries and half-hourly tariffs have dragged the wiring back into the living room. Craig Lewis, who watched the corporate network solve the same problem, says the answer is to hide it again.
Energy Optimisation
Every heat pump comes with an efficiency figure. None comes with a measure of what its heat actually costs. C-COP puts the two together, and shows how the same machine can beat gas or cost more to run, depending only on when it operates.
Energy Optimisation
The Government's fuel poverty committee says the case that heat pumps cut bills for low-income homes "has yet to be proven". A year of data from one instrumented house says the heating passed. The committee is right that the evidence is missing. It already exists in the meters. Nobody is reading it.
Energy Optimisation
We have found a villain for our electricity anxieties, and it is the AI data centre. But the same digital energy system runs into every child's bedroom in Britain, and the answer may start at the kitchen table, between five and six.
Risk and Governance
What a regulator found inside 30 UK employers, and the four questions a board can ask about its own hiring without understanding a single line of the model.
Two company cars, one smart tariff, and 1,152 half-hours of grid data. What we found in our own ledger did not entirely flatter us, and that is rather the point.
Twelve months of real bills, a heat pump, two solar arrays, a battery, an EV, and every number verified against the smart meter. Including the ones that turned out to be wrong. Last July, Octopus Energy paid me £83.36. Not a refund. Not a rebate. My electricity bill for
AI
Electricity took forty years to change the factory. AI does not have to take that long, but only if we learn why the wait happened at all.
There's a quiet inefficiency sitting on school roofs all over the UK, and once you see it you can't unsee it. Thousands of schools have done exactly the right thing. They've put solar on the roof. Some funded it themselves, some through community schemes,
AI probably won’t replace work in one dramatic moment. More likely, it will do what technology has always done: quietly remove pieces of work until one day we look around and realise the job has changed. When I started my career, every office had a Doris. She was not
AI and Software
There are moments in technology when a new tool arrives and, almost immediately, feels less like a product and more like a warning. OpenAI’s Codex and Claude Code are beginning to feel like that. At first glance, they are simply the latest advance in software development: clever assistants that
Risk and Governance
It rarely does. Long before AI arrived, organisations had already spent decades working out how to manage risk, change and accountability in complex systems. In IT, that thinking found its way into ITIL. Change Advisory Boards. Continuous improvement. Structures that, at their core, were designed to answer a very human
