The AI Boom Is in Your Cost Plan. Most SME Developers Have Not Noticed Yet.

If you run a small or mid-sized development business in the UK, you are unlikely to have spent much time this month thinking about NextEra Energy’s proposed $420bn merger with Dominion, or Apollo’s forecast that $3 trillion of capital will flow into AI infrastructure by 2028. You should. Not because the deals directly matter to you, but because the capital cycle they represent is already working its way into the schemes you are trying to deliver.

The impact is not dramatic, which is exactly the issue.

There is no single forcing event. Instead, pressure is building steadily across three areas where SME developers tend to feel it first, and most acutely, because balance sheets are tighter.

Trades and materials. Hyperscale data centre build is drawing on the same switchgear, transformers, steel, MEP packages and labour as your projects. They are buying earlier, on firmer terms, and at scale. The result is not always a visible jump in cost. It is extended lead times, and contractors are becoming more selective about which jobs they prioritise.

Grid and power. A mid-sized residential scheme could previously assume a grid connection. That is no longer reliable. DNO queues across much of the UK are now driven by large industrial enquiries. For an SME developer, a delay to energisation is not an inconvenience. It can move a scheme from viable to marginal.

Funding terms. Lenders are leaning toward assets with long, contracted income. That shift is filtering through to residential and mixed use. Margins are firmer, covenants tighter, and lenders who were flexible on the last deal may approach the next one differently.

What separates the schemes that get through.

SME developers have always been the most adaptable part of the market, and the projects that progress will have been prepared differently from the ones that don't.

Schemes that hold up are being underwritten against current conditions, not last year’s assumptions. Older cost plans tend to miss where risk now sits. Programmes need to reflect friction in grid and procurement. Funding structures need to stand up to a less forgiving market.

Site selection is also changing. Grid headroom, water capacity and local planning dynamics are carrying more weight. A low entry price does not offset unresolved infrastructure risk.

Funder relationships are more direct. The lenders we see respond best to developers who surface issues early and show they are tracking the right pressures. That position is materially stronger than waiting for problems to appear in reporting.

Where Axo helps

Our work with SME developers has shifted in the last twelve months toward exactly these pressure points.

We are screening sites earlier against infrastructure and consenting constraints.

We are repricing live schemes to isolate where exposure actually sits.

We are helping reprogramme around longer lead times.

We are stress testing funding structures built for a different set of conditions.

Our project monitoring work also gives us real-time visibility across a range of SME schemes, which informs how we advise.

What comes next

These capital flows will not reverse in the next eighteen months. The question is not whether to respond, but how quickly to revisit the assumptions already built into your projects.

For schemes at feasibility, in design, or in front of funders, now is the point to test those assumptions properly.
