If you spend long enough in the renewable sector, you begin to recognise a rhythm that has nothing to do with engineering and everything to do with policy. The industry does not grow like a tree; slowly, predictably, layer by layer. It grows like a heartbeat. A spike, then a lull. A rush of activity, then a hollowing out. Subsidy arrives and the market surges. Subsidy disappears and the market folds in on itself. A political announcement sparks a hiring frenzy. A budget line vanishes and half the workforce evaporates.
It is not incompetence.
It is not immaturity.
It is simply what happens when centralised policy meets decentralised delivery.
Contractors understand this better than anyone. They are the ones who live through the whiplash – scaling teams at impossible speed one year, letting them go the next; buying new vans and tools during the boom, selling half of them during the bust; trying to build competence while the ground shifts beneath their feet. In a world where customer demand, political sentiment and wholesale prices can change overnight, the renewable installer’s life often resembles that of a surfer: hold your nerve, stay on your feet and hope the next wave is kinder than the last.
The problem is not the wave itself, it is what the wave does to the structure behind it. During boom periods, recruitment outpaces experience. New installers join faster than the sector can train them properly with seniors stretched thin. Coaching becomes compressed and documentation becomes something that will “be sorted later,” because the priority is to meet the deadline or lose the funding. Quality doesn’t collapse, far from it but it becomes uneven. A beautifully executed system might sit beside one that bears all the hallmarks of a team working at the limits of speed rather than the limits of craft.
Then comes the bust. A subsidy window closes. A policy changes. The economics shift. And almost overnight, the scaffolding that held the boom in place falls away. Firms contract. Some collapse. Apprentices drift into other trades. Engineers move on. Vehicles are returned. O&M teams shrink and, most importantly, the documentation that should have underpinned the next twenty years of asset care gets left behind on laptops, in inboxes, on forgotten USB sticks or in the memories of staff who no longer work there.
What remains is the asset – still generating, still quietly feeding the building and yet carrying the scar tissue of a disrupted market cycle.
Asset owners rarely realise what has happened. A system that worked perfectly in year one still works in year seven; the degradation is too slow to see in day-to-day bills. But beneath the surface, the aftershocks of the boom-bust cycle linger early mistakes that were never corrected; tightening DC insulation levels that no one has measured since commissioning; connectors that have weathered ten summers without being checked; string imbalances unnoticed because monitoring was never installed; record-keeping that exists only in the memories of people who have moved onto other things.
This is not the fault of contractors, it is the fault of a system that asks contractors to build long-term infrastructure on top of short-term incentives.
Markets optimise for speed – rapid scaling, rapid response, rapid wins. Infrastructure optimises for the opposite – slow change, consistency, method, evidence, predictability. When the two collide, one of them has to give and it is almost always the infrastructure that bends. Not dramatically, not catastrophically, but quietly, grain by grain, until the cumulative effect becomes visible years later.
Boom creates momentum, bust creates fragility. The combination creates risk that no one intended yet everyone inherits. The renewable transition is too important to be governed by pulse alone. We cannot build a national layer of decentralised generation on top of rhythms designed for quarterly targets and political cycles. We cannot expect reliability to emerge naturally from conditions that work against the very things reliability requires.
What the industry needs is not protection from volatility – change is inevitable but insulation from its effects. A way for method to remain steady even when the market convulses. A way for documentation to persist even when companies change shape. A way for competence to grow even in years when hiring stalls. A way for asset health to remain visible even when budgets tighten.
This is not a market problem, it is a system problem and therefore a system design problem. If we want decentralised energy to scale with the confidence the old hive once enjoyed, we must build the tools, standards and cultural architecture that allow reliability to survive the booms and the busts. Only then can the next decade look different from the last.
Social housing did not create this problem; it simply revealed it early. Large portfolios, tight margins and long asset lives make neglect visible sooner, but the same mechanics are at work everywhere. Commercial estates, industrial parks and private portfolios are all moving along the same curve, just a few years behind. The lesson here is not about tenure. It is about what happens when infrastructure outlives the organisations built to look after it.
