BLOG — MAY 2026
Thirteen posts. Six registers. One discipline.
Blogs from Probari on AI assurance in regulated energy supply. Each one grounded in the corpus that sits behind the platform.
What good AI governance looks like in GB energy.
It is not a slide. It is not a policy. It is a practice that the regulator can see, the operator can run, and the customer never has to think about. Most suppliers have the parts. Few of them have a working assembly.
AI transformation is not an IT programme.
When a supplier hands AI transformation to its IT function, it has already chosen the wrong owner, the wrong success measure, and the wrong language to talk to its regulator in. The fix is not bigger IT. The fix is the right operating model.
DIAMC: a working pattern for AI in regulated environments.
Discover, Identify, Assess, Mitigate, Confirm. Five verbs that turn an AI ambition into a use case the regulator can recognise and the operator can run. The pattern is portable. The discipline is not optional.
The frontline as intelligence centre.
The agent on the call is the first to know what the AI got wrong. The supplier that captures that signal — quickly, without blame, and inside its assurance — is the supplier that learns faster than its regulator can write to it.
The next wave of energy debt is coming. AI without guardrails will make it worse.
The £500m Debt Relief Scheme is not a finish line. It is a starting gun. The suppliers whose AI is making affordability, eligibility and outreach decisions without an AIIA will be visible — to their customers, to their regulators, and to the press — within the first review cycle.
If you cannot show your AIIA on Monday, you have a problem.
A missing AIIA in 2024 was a maturity gap. A missing AIIA in 2026 is an exposure. By 2027, when MHHS is in flight and the Debt Relief Scheme has had its first cycle, a missing AIIA will be a finding. Findings produce remediation programmes. Remediation programmes are expensive, public and slow.
MHHS is closer than your AI governance is ready for.
Market-wide Half Hourly Settlement is not nominally an AI programme. The data-handling, anomaly-detection and customer-impact questions inside it effectively are. Suppliers that have not folded AI assurance into their MHHS programme will be asked, in writing, why the volume of AI-mediated decisions has expanded faster than the governance around them.
The vulnerable customer your AI just disadvantaged: a regulator's-eye view.
From the regulator's desk, the question is not whether the AI is sophisticated. It is whether the supplier knew it would behave this way, and what they did about it. "We didn't realise" is not a defence. It is a finding.
Three Ofgem decisions in 2026 that will catch unprepared suppliers.
Not warnings. Decision points. Each will be visible in the post-bag of every regulated supplier within the year. Each will reward the suppliers whose AI assurance is already in place.
Brokers, the TPI Code is becoming a licence. Your AI tools come with you.
The voluntary Ofgem TPI Code, administered by the Retail Energy Code Company, will not stay voluntary. The October 2025 Government consultation set out the direction of travel: a statutory authorisation regime for Third Party Intermediaries, run by Ofgem, with a sunrise period measured in months not years. If your brokerage uses AI for prospecting, pricing, contract recommendations, complaint handling or any customer-facing decision, that AI is in scope on day one.
Suppliers, your TPI risk is now your AI risk. RECCo, the SLCs and what changes in 2026.
You already carry licence accountability for what your brokers do under SLC 20.5, 20.6 and 27.8A. AI in the broker channel does not move that accountability — it concentrates it. The supplier that does not know which AI tools its TPIs use to win, price and onboard its customers is the supplier that will read about them in an Ofgem decision.
AI in Irish energy supply: what the CRU will and will not tolerate.
The Commission for Regulation of Utilities is not Ofgem with a different accent. It regulates a smaller market, an all-island wholesale arrangement and a customer base that has lived through one of Europe's sharpest price shocks. Suppliers operating into the Republic of Ireland that import their AI assurance posture from GB without translating it will be told, politely, that they have not understood the regime.
The UREGNI question: AI assurance under the Northern Ireland Codes of Practice.
Northern Ireland's Utility Regulator does not get the column inches Ofgem and the CRU receive. That is not an indication of a lighter regime. It is an indication of a smaller market with a denser code framework, an equality duty written into statute, and a customer base where prepayment and vulnerability are not edge cases but the operating norm.
