Slow Burnham: on the incompatible time horizons of British statecraft

“Fiscally constrained” is so often used to describe Andy Burnham that one starts to wonder if it is his unfortunate medical condition. And perhaps it is a bleak prognosis. He is the 59^th Prime Minister of Britain and the seventh since Brexit, since which time the average tenure of a British PM has been just seventeen months.

Is structural uncertainty our zeitgeist?

Short-termism binds UK political thinking. We should be scoring Chancellors over the five-year window that has historically determined the success of their policies, but Gilt investors are repricing British promises within hours. Since 2022’s Trussonomics, it is burned into our collective psyche that policies without concrete fiscal support will be quickly cut at the knees no matter the cost, and in that example the cost was an emergency intervention, a repricing of every mortgage in the country, and two careers. British policymaking is faced with a structural issue therefore: a Prime Minister who needs to think in decades cannot avoid being judged over weeks.

But almost nothing that matters to this country can be done in seventeen months. A grid connection takes years. A transformer order takes years. Restoring topsoil takes decades. Solving pollution in our rivers is no overnight matter. Training the engineers to fix any of it happens over years. This means the interesting question isn't whether Burnham is or isn’t a long-term thinker, it's whether he can afford to be.

Have we become punitive in how we judge UK policymaking?

Since 2022, Chancellors have to govern with one eye on the desk. Wherever decisions are made that ruffle feathers (Reeves’ NIC hike), bond markets respond accordingly.  

The result is that a government under credibility pressure reaches for what can be costed, announced and seen, because those are the things that demonstrate control. Anything that can't be scored inside a forecast window doesn't register in policymaking as it once did.

Burnham took office four days after the Commons rose for summer recess, which bought him a fortnight of daily announcements. VAT off electricity from October, worth around £45 a year per household. The bus fare cap back to £2. Business rates for pubs, clubs and music venues cut 20% from April, a £100m package that the government says is fully funded. Social care reform with Baroness Casey's commission pulled forward from 2028 to next year. £8.4bn to Defence for the fourth phase of Dreadnought.

Look at what these have in common. Each is legible to a voter inside a news cycle. Each is costable inside a forecast window. And the two biggest - energy VAT and bus fares – are in the CPI basket, so they have an eye to pushing measured inflation down while trying to put money in people's pockets. That is the perfect instrument under a credibility regime: visible, funded, and flattering. The Bank held Bank Rate at 3.75% at the end of July. Noting, though, that three of nine members wanted a hike, and its own projection has CPI peaking near 3.2% in the fourth quarter. This pressure comes from the Strait of Hormuz.

Security, security, security

The Iran War brings to mind the big issue triptych: energy security, food and water security, defence security. These are the existential issues facing our economy and the outlook feels bleak because each needs serious investment.

A big question is funding our spending needs. The UK deficit is enormous and extremely tightly balanced. As we have explored in many previous blogs, we need a more productive economy. This is because Labour can raise tax receipts from two mechanisms: increase our country’s profitability, or hike taxes on existing profits. The latter is the quicker and easier route, which will make us all want to work less, and the former the longer more challenging but infinitely better route of stimulating the economy. Decisions on the above will be invariably judged in the bond markets because they are fiscal policymaking measures by nature.

Then there is the far more existential question that forms the crux of the incompatible time horizons: how do we power it all? Long-term investment in power infrastructure will be viewed as inflationary and punished in the bond markets. But look at what the queue actually looks like on the ground. Near Aberthaw in Wales, developers face a five-year wait for power on a former coal site that already has seaside cooling water and a 1.5GW connection wired in. For a site with no existing infrastructure, they are looking at a decade. There are over 2,000 substations waiting in the connection queue, and the average transformer already on the network is between 35 and 60 years old against a recommended working life of 35 years. Over the next ten years the network needs to deliver twice the capacity of the last decade in half the time. The answer, as I have said many times before, is stimulating private capital investment into the SMEs powering Britain. Burnham can focus on immediate policy decisions to balance the deficit, and private capital can take the long term view on turbo-charging British infrastructure.

Can the Government make its own investment decisions and create off balance sheet assets in PuFins?

One measure being explored by the UK’s new Chancellor, Healey, is a loop hole in deficit spending. If the money is channelled via public institutions that make investments (loans, equity investments, guarantees) to the private sector, the assets created mean that there is no measured impact on national debt.

This is great, but it is narrower than it looks and investment is inherently risky. The rules already require these institutions to make an overall return equivalent to government borrowing costs, which quietly rules out most of what you would actually want to fund. Defence is the clearest example. The typical government investment in the sector will be a start-up, which immediately removes the de-risked investment instrument of a cash paid, amortising loan. Start-ups invariably need equity, the highest risk strategy there is.

Investing in a start-up does not at all mean there will be a return attached. Generating returns necessitates that the capital deployed is restricted and measured against the expected growth of the company. Remembering, of course, that the company may not grow at all. That leaves the government exposed to failed investments funded by its balance sheet, with an asset match that has evaporated. And it does not work at all for the things defence actually needs to buy. Tanks, jets and warships are built by primes with the government as the only customer, and the Institute for Government's chief economist calls financing those this way a mirage that still ultimately rests on government borrowing.

Burnham should consider stimulating this investment in part by government but also encouraging a spread across private alternative investment funds.

So is the North Sea row the long-term decision?

Burnham has said he's open-minded about expanding North Sea drilling. With the Strait of Hormuz effectively shut and the worst energy crisis since the 1970s underway, producing your own hydrocarbons rather than shipping them past an active warzone feels reasonable.

I'm not going to adjudicate that argument, because hydrocarbon extraction isn't my field and the case runs on details I'd be pretending to command. The emissions accounting is contested, the North Sea is a declining basin, and a good deal of what we import arrives by pipeline from Norway rather than as LNG. Carbon Brief and the Climate Change Committee have both published on it and are worth reading directly if you want the numbers. My point is a different one.

The North Sea row is a decision with a five-year horizon being conducted as though it were a decision about 2050. Whatever new licences deliver, they deliver slowly, into a basin that is shrinking anyway, and they do nothing about the constraint that binds everything else.

That constraint is the network. The better decision is serious investment in our electricity infrastructure, in configuring it for renewables, and in more intelligent positioning of generation and storage across it. You will have seen my writing on this in detail elsewhere. The fundamental conclusion again is that sensible private capital investment offers enormous support here.

And the problem with no constituency at all? Food.

Britain produced 60% of its own food by value in 2025, down from 65% the year before, and 72% of the food it can actually grow here. In the 1980s that was closer to 75%. The Energy and Climate Intelligence Unit reads the latest fall as a clear signal of climate change, driven by the cost of climate-affected imports – coffee, cereals, beef – rather than by any collapse in domestic output.

The structural picture is worse than the headline. Around a third of imported food comes from countries facing significant climate risk, so the buffer is itself exposed. Domestically, the government's own food security reporting names climate change, soil degradation, water quality and biodiversity loss as the biggest medium-to-long-term risks to production.

The mechanism is elegantly horrible. A warmer atmosphere holds roughly 7% more moisture per degree of warming, which gives you heavier rainfall and deeper droughts from the same physics. Wetter winters that stop you planting, drier summers that strip soil moisture and leave land open to erosion. Demos puts arable soil losses at 40%, estimates nature degradation could cost 6% of GDP by the 2030s and reckons climate change adds 9% to the average family's food bill by 2050, rising to 13% for the poorest tenth.

Burnham has said little about this. Not soil, not farm policy, and just signals so far on water. Three weeks of announcements covering social care, devolution, energy bills, welfare, small boats and nuclear submarines, but nothing on agriculture.

This is the cleanest demonstration of my argument available. Soil degradation produces no news cycle, no by-election and no gilt move. It is the purest long-horizon problem Britain has, and the system has no receptor for it whatsoever.

Are these separate problems?

Britain imports 63% of its gas and 40% of its food, a third of that from places climate change is already destabilising.

Conflict over energy chokepoints lifts the price of fuel, fertiliser and freight at once, and lands on food. Climate change degrades our growing conditions and our suppliers' simultaneously. Rearmament competes directly with electrification for the same finite pool of welders, engineers and grid capacity: Dreadnought alone takes nuclear jobs from 47,000 to 65,000 by 2030, with 20,000 apprenticeships by 2035. Serious thought needs to go into prioritisation around energy transition needs and defence needs because punitive inflation means that energy pricing is a national threat.

Which is the thing I keep saying in different clothes. You cannot buy your way out of a physical constraint. No fiscal instrument produces a transformer, a trained engineer, a working water abstraction system or three inches of topsoil. These need long term investment and cannot be ignored because the political eye is focussed on bond markets.  

So how does anyone escape a seventeen-month clock?

Change what counts as debt and stimulate private investment in the most critical sectors. Burnham is already looking at PuFins as I have explained above, but this carries immense risk of backfiring. Broader measures that recognise the asset alongside the liability are a powerful lever, but they will be given longevity where private capital investment is also structurally encouraged.

Multi-decade programmes with committed contracts, industrial footprints and cross-party consent. These will survive changes of government because unwinding them costs more than continuing. We know how to do this when the thing being built is a submarine. There is no reason it can't be done for energy and food security.

Devolve the horizon. Metro mayors retaining a share of locally raised revenue, No 10 North, decisions taken by the people who live with them. A mayor with a fiscal base has a longer effective horizon than a Cabinet minister with a reshuffle coming.

So does he understand it?

The parts he understands are the parts he lived.

Manchesterism is a coherent theory about who decides. The reason so little gets built in Britain usually isn't that nobody wanted it. It's that the decision sat with someone in Whitehall with no stake in the outcome. Push it to the people bearing the consequences and you may get faster answers. Networks, connection queues, planning consents, skills pipelines: all in principle devolvable. Britain is the most fiscally centralised of the 38 OECD economies, with roughly 5% of taxes and 20% of spending decisions taken locally, so there is a great deal of room to move.

None of this is an argument that Britain is doing badly because things take a long time. Things take a long time. A grid is a decade of work, a transformer factory is a twenty-year asset, and soil recovers on a schedule. That is not a failure. It is the physical reality.

So the test I'd apply on 28 October isn't whether the Budget balances or whether Burnham's policymakers win the week. We will still be installing transformers in 2036, and that is fine. What matters is whether we are funding them as a decade-long programme, or re-deciding every autumn whether we can afford them.
