Can we build it?

We’ve spent this report freeing Britain from being a hostage to global capital markets. But ask any engineer about constraints, and they’ll tell you the same thing: clear one bottleneck, and you don’t get perfection. You get the next bottleneck.

Ours is political, first. We need politicians willing to do this. That we need better politicians is hardly a new complaint, so let’s take the need for political will as read and move to the harder question.

The next constraint is the state’s own capacity to run a project. And here, this report has already solved the two most common causes of project failure. Clear long-term goals. Clear long-term finance. Most government programmes fail for lack of one or the other. Ours has both. That hands our civil servants the fighting chance most of them have never been given.

But a fighting chance needs a legal shield. We need mechanisms that keep the money and the mandate running when the minister in the office changes. We need to end the eighteen-month churn – the search for a policy announcement smart enough to survive one reshuffle, then get quietly dropped for the next one.

“Which brings us to the real constraint of this whole model. Not the money. Not the politics. Can the British state organise and mobilise what we’ve unlocked?”

We’d answer that with a question of our own: in this moment of global upheaval, if the British state isn’t being rebuilt for resilience, then what exactly is it for?

Here’s how we do it, without inventing a single new quango.

To ensure our programme never triggers the demand-pull inflation we exposed in Chapter 19, the state must implement a strict operational rule: First we build capacity.

We should operate with a strict Capacity Guardrail. Before releasing each tranche of funding, the Treasury draws on two standing assessments that already exist: the National Infrastructure and Service Transformation Authority on physical and material capacity, and Skills England on workforce capacity. No new board. No new quango. The Treasury doing its existing job properly, with expertise already on the payroll.

Both need resourcing for the scale of the task, which neither currently is. And both need to know what capacity actually exists, which sounds like the hard part and isn’t.

Most of it is already counted. Every heat pump installer holds an MCS certification. Every gas engineer is on the Gas Safe register. Every retrofit assessor sits on a PAS 2035 register. These are live counts of people qualified to do a particular job, by postcode, updated as they qualify and as they lapse. No firm can inflate them, because somebody else keeps the list. What has never happened is anyone collating them as a national picture.

The rest comes from the way the work is let. You can’t run a tender for every street. So retrofit runs on a standing framework: firms qualify once, and the work is called off against it. If you run a small building firm you already know the alternative. You are told there is public work coming. You look at the tender and it wants a bid writer you can’t afford to employ. So you don’t bid, and the contract goes to somebody bigger from somewhere else.

The price of the fast track is telling the truth about what you can do. How many people you employ. What they are qualified for. What you could take on if the order book doubled. Firms that misreport come off the list. Combined authorities have run adult skills this way for years and it works, because both sides want it to. The public body needs to know the capacity is real. The firm wants the work to keep coming.

If anything is still missing, there is a route that does not need a bill. The Statistics of Trade Act 1947 already lets a minister require businesses to file returns, and what can be asked for is set out in a schedule that can be updated by order. A debate, a vote, done.

The assessments are published before the funding decision, not after it. Neither body gets a veto. The Office for Budget Responsibility has no veto either, and it has shaped every fiscal decision for fifteen years, because a government that ignores a published assessment has to explain itself in advance and in public. That is a stronger discipline than a gateway, and it does not create a new bottleneck for a programme to get stuck in.

One caveat, because it matters more than it sounds. Capacity is not a national number. A finding that Britain has enough bricklayers is no use if they are all working in the South East and the houses are going up in Leicester. The assessment has to be granular enough for a combined authority to act on, or we will repeat the familiar mistake of matching a national average to a local shortage and wondering why the scheme underperformed.

Training the workforce

Britain is not short of graduates. On STEM subjects broadly we sit level with America and Germany.

The gap is specific, and it’s in the disciplines that build things. Just 8.9% of UK bachelor’s degrees are awarded in engineering, manufacturing or construction. Germany manages 24.7%. China 33.2%. Even the OECD average is 12.6%.¹

It shows up on site. The Institution of Mechanical Engineers puts annual demand at 124,000 engineers and technicians against a shortfall of 37,000 to 59,000 a year. In 2025, 76% of engineering employers reported difficulty recruiting the skills they needed, and Cambridge’s industrial policy group calls the shortage structural, not cyclical.² Separate research puts 184 major projects, worth £542 billion, at risk from this skills gap.³

“No amount of off-market finance fixes a housing programme if there is nobody qualified to run the job. By signalling secure funding we should start to secure this skills pipeline immediately.”

The money supply expands only as fast as we expand the real-world, organisational power to build. By pacing our investment in line with this guardrail, we ensure that every pound injected into the economy maps directly to an expansion of production..
