Across the UK energy TPI market, a number of pressures are arriving in parallel this year. On their own, each is familiar. Taken together, they are asking a question that most of the sector has not had to answer directly before.

That question is not primarily about energy prices, or regulation, or commercial model. It is about data posture.

The pressures, in summary

From 1 April, TNUoS charges rise by approximately 64%, the single largest year-on-year move since the charge was introduced. This is the start of RIIO-ET3, Ofgem’s new five-year price control period. The five-year forecast from the National Energy System Operator (NESO) shows these charges climbing further rather than settling back.

Alongside this, Ofgem’s scrutiny of TPI conduct continues to tighten. Transparency, commission disclosure, and consistent customer treatment are moving from principles to evidenced expectations.

For the large share of the sector that is now PE-backed, there is a parallel pressure. Acquisition theses expect rapid value creation, clean financial consolidation across acquired entities, and trustworthy numbers for the board.

And running through all of this is the longer arc of decarbonisation. TPIs are increasingly expected to advise clients credibly on net zero transition, which itself depends on data the TPI may not currently hold at the right quality.

Why they combine into a data test

None of these pressures is new in isolation. TNUoS changes every April. Ofgem scrutiny has been building for years. PE ownership in the sector is well established. Net zero reporting is a slow build.

What is newer is that each of them now lands as a data question.

When a client asks what April’s TNUoS change means for their specific contract, the firms who can answer in hours have modelled per-client exposure against their own contract terms and usage data. The ones who answer in weeks are pulling numbers from three or four systems by hand.

When Ofgem asks for evidence of consistent commission disclosure, the firms who respond cleanly have the audit trail in one place. The ones who do not are reconciling spreadsheets and email chains under deadline pressure.

When a PE board asks why last quarter’s margin came in below plan, the firms with a unified view of contract, counterparty, and volume data can narrate the story. The ones without are explaining the reconciliation process instead of the numbers.

And when a client asks the TPI to help evidence progress against net zero commitments, the firms who already have sector-specific data maturity take the work. The ones who do not lose it to a competitor who does.

The pattern beneath the pressures

Seen separately, these look like different problems, each calling for a different response. Seen together, they are the same problem.

The sector has built up, quite reasonably, as a sequence of point solutions. A CRM for customer data. A procurement platform for contracts. A billing system for volumes. A spreadsheet for margin. Each was bought at a different time, often with a different rationale, sometimes by a different company that has since been acquired.

That architecture worked well when the questions coming at the TPI could be answered inside one system at a time. It works less well when the questions now require the systems to be stitched together to produce an answer.

The firms we see managing 2026 well are not necessarily the ones that have invested most in technology. They are the ones that invested earliest in the governance layer: who owns each data domain, what quality standard applies, how the systems hand off to each other, and how disputes between departments get resolved.

Technology follows that work. It does not precede it.

What this means in practice

A useful framing question for leadership teams this year is less “what should we buy?” and more “what would we need in place before any platform investment would actually pay back?”

We have explored the organisational side of this question in more depth here. In most cases, the honest answer involves three layers of work before the tooling decision becomes the right conversation.

The first is leadership alignment on data as a strategic asset, not an IT cost. Without that, every downstream investment is at risk of becoming shelfware. The second is capability: whether the organisation has enough data literacy, spread across enough of the business, that the investment gets used. The third is governance: clear ownership, quality standards, and a framework for how data-related decisions flow.

Only after those three are in good shape does platform selection tend to pay back. The TPIs that have invested in that sequence are the ones that will find the next twelve months straightforward.

The ones that deferred are, in most cases, not short of technology. They are short of the organisational conditions for the technology to deliver.

What this looks like in the field

The firms that get the sequence right look different from the outside. When a customer asks a trader for a complex re-quote, the answer arrives in minutes rather than hours because the deal history, credit exposure, and margin pattern sit on one screen. When finance closes a period, the books land on day three rather than day fifteen, because data integrity is being maintained at source rather than corrected at month end.

Our Amber and Switch2 engagements are recent examples of where this plays out in practice, in both cases with an event-driven integration layer doing the heavy lifting once the organisation was ready to use it.

A quieter moment than it looks

This is a quieter commercial inflection point than it will appear in hindsight. It is unlikely to show up dramatically in the monthly numbers. It will show up, over the next twelve to eighteen months, in client retention, in margin resilience, and in which firms the PE sponsors are most confident about.

For TPIs thinking about where to invest attention this year, the specific pressures matter less than the underlying posture. A firm with a strong data posture can handle the TNUoS year, the Ofgem year, and the PE year in parallel. A firm without one will find even one of them absorbing.

Where is this posture currently most under strain?
