Britain’s most expensive policy choice may be the one it never voted for: the slow demolition of its skilled trades. As of late 2025, 957,000 young people aged 16-24 in the United Kingdom were not in education, employment, or training — the second-highest NEET figure in over a decade. At the same time, construction alone carries more than 140,000 vacancies, roughly 750,000 workers are expected to retire by 2036, and the Construction Industry Training Board estimates that some 47,860 additional workers must be drawn into the sector every year between 2025 and 2029 just to stand still. The British construction workforce, on absolute headcount, has fallen to its lowest level in nearly twenty-five years.

That is not a labour shortage. It is a structural depletion — the kind of fat-tailed risk that compounds silently for a decade and then snaps the housing market, the energy transition, and the defence-industrial base simultaneously. Britain does not have a skills gap. It has a skills trench.

Israel, by contrast, treats workforce formation as a sovereign function rather than a market by-product. Through mandatory national service, the IDF operates — in the words of Israel’s own Institute for National Security Studies — as a “national training enterprise,” qualifying soldiers each year for hundreds of professions: technicians, mechanics, electricians, logisticians, drivers, armaments and maintenance personnel, programmers, data analysts. Programmes such as Atidim and the Technological Reserve (Shocharot) embed vocational study directly into the pipeline between school, IDF service, and the labour market. The 8200 cyber unit and its analogues have famously fed Israel’s start-up economy, but the more underrated story sits in the Combat Engineering Corps and the Logistics Corps. A nineteen-year-old conscript completing the Engineering Corps’ heavy-plant track demobilises roughly three years later as a certified plant operator with live field experience across bridging, demolition, and earthworks — a profile that a British civilian apprenticeship system takes five to six years to produce, if it produces it at all. The Logistics Corps does the same for vehicle mechanics and HGV operators; the Air Force’s technical training apparatus feeds avionics technicians and ground-equipment fitters straight into Israel Aerospace Industries, El Al, and the maintenance shops of the country’s defence primes. The civilian labour market does not have to find these people. The state has already trained, certified, and networked them.

The structural comparison

This is the financial economics of nation-building. A compulsory service framework is, in option-pricing language, a long-volatility position on national capability. The standard market objection — that prices will draw workers into the trades when shortages bite — assumes demand shocks arrive sequentially and uncorrelated. They do not. A Hormuz closure, a North Atlantic shipping disruption, a major hurricane retrofit cycle, a NATO mobilisation surge: any one of these draws on the same pool of welders, electricians, fitters, and plant operators. Their tails are joint, not independent — and joint tails are precisely what a thin training pipeline cannot serve. The voluntary market can absorb sequential shocks; it fails on simultaneous ones. Britain, by relying entirely on the voluntary route, has effectively sold that option for premium income — lower public spending, more university-track 18-year-olds, looser immigration valves to plug the gaps — and now finds itself short volatility at the wrong point in the cycle.

The British policy debate has flirted with the idea. Rishi Sunak’s May 2024 election proposal — 30,000 full-time military places plus weekend community service for the remainder — was lampooned, then buried with the Conservative defeat. The underlying intuition was directionally right and substantively far too thin. A weekend a month sorting donations in a charity shop does not retrofit a Victorian housing stock, electrify the grid, or restore the merchant shipyards. A genuine national draft for the trades has to do real work.

Le Chatelier’s principle, borrowed from physical chemistry, holds that a system under external stress will re-equilibrate to counteract that stress — but only if it retains the institutional mass to respond. Britain’s voluntary skills market does not. Apprenticeship enrolment has stagnated, university debt distorts the price signal between graduate and vocational routes, post-Brexit migration has thinned the EU pipeline that previously masked the deficit, and over a third of construction workers are now above 50 against fewer than one in five below 25. The system cannot self-correct because the feedback loop is broken. A national draft restores institutional mass; nothing else credibly does.

A British version should accordingly carry weight. Twelve months of compulsory national service for every 18-year-old, with three streams. The first, military and cyber, modelled directly on the IDF’s technical corps. The second, civil construction and infrastructure, tied explicitly to the 1.5 million homes target and the net-zero retrofit — bricklaying, plumbing, electrical, HGV, plant operation. The third, care and emergency services — NHS auxiliary, fire, coastguard, lifeboats. Pay set at the National Living Wage. Recognised credentialing through CITB, T-levels, and NVQs at exit, so a year of service yields a qualification rather than merely a uniform photograph. University entry deferred without loss of place. Apprenticeship pathways accelerated for those choosing to remain in the trades.

The objections will be familiar. Compulsion is illiberal. It is expensive — Sunak’s scheme was costed at around £2.5 billion. It risks producing reluctant tradesmen rather than enthusiastic ones. Each objection has a reply. Compulsion already exists for taxation, jury service, and education itself up to 18; the question is whether a year of state-funded skill formation is more or less coercive than a state-tolerated drift into long-term NEET status, which lifetime-scars earnings and mental health. £2.5 billion is less than a month of the annual housing-benefit bill, and the TUC’s own modelling of a far more modest youth guarantee found a benefit-cost ratio of 2.8 — meaning every £1,000 of net spending generates £2,800 of long-run return. As for reluctance: Israel’s recruits are not all volunteers either, and the IDF still manages to produce both a start-up economy and a deep bench of military technicians. Compulsion plus dignity plus credentials plus paid work is not press-ganging.

There is a second-order dividend that conventional cost-benefit analysis routinely misses. Israeli national service also operates as a labour-market network technology. Former unit-mates hire each other, vouch for each other, and collapse the information asymmetries that ordinarily clog the trades — where a small contractor taking on an apprentice is betting blind on temperament, reliability, and stickiness. The IDF effectively pre-screens the population on all three. Britain’s trades currently suffer not only a numeric shortage but a screening-cost problem: small builders cannot afford the risk of a bad apprenticeship, so the marginal hire never happens. A national service cohort delivers what the private market under-supplies — verified, trained, networked tradespeople with a credible signal attached. The 957,000 NEETs are not merely an economic statistic; they are a market failure dressed as a social problem.

Britain need not import the Israeli model wholesale. The Swiss militia tradition, the Singaporean SAF, the South Korean conscription system all offer adjacent templates. What it must import is the underlying logic: that a serious country does not outsource its workforce formation to the random walk of individual preference and EU labour mobility. It plans. It trains. It conscripts capability before incapability conscripts the country into decline.

There is a tradesman’s saying: measure twice, cut once. Britain has measured the problem three times, four, five. The cutting is overdue.
