Addressing the structural reasons why the UK is so dependent on imports, meanwhile, is likely to be trickier. Back in the 1970s, the country had 18 refineries – but that’s now down to four.

“I think there is probably a point in saying, actually, do we need more resilience from a homegrown perspective in terms of our capacity in the UK to be able to refine a higher proportion of our fuel?” says Skybus’ CEO Jonathan Hinkles.

The question is how that could be done. The remaining refineries have already been asked to prioritise jet fuel production. But according to Amaar Khan, “this doesn’t happen overnight, and doesn’t result in a significant increase in jet fuel output”.

One option could be to boost local production of Sustainable Aviation Fuel (SAF). A synthetic fuel, it can be derived from wastes, such as old cooking oil and agricultural residues; from dedicated energy crops; or from using renewable energy to convert water and carbon dioxide into liquid hydrocarbons known as e-fuels.

So far SAF, as the name suggests, has been promoted mainly for its environmental credentials. These can vary widely depending on the method used to make it, but in general burning SAF adds less carbon to the atmosphere than burning fossil fuels. Both the UK and the EU have mandates to significantly increase the amount of SAF used over the next 25 years.

However, the industry is in its infancy. There is relatively little SAF available at the moment, a large chunk of what we use comes from East Asia, and it is very expensive – typically trading at more than $1000 per tonne more than conventional fuel. Nevertheless, Hinkles believes if these problems can be overcome, SAF can help reduce our reliance on foreign imports.

“It really becomes a question of; can you actually get SAF? Can we scale up production of SAF at a meaningful rate in the UK or Europe to take over an increasing proportion of jet fuel supply?”, he says.

Green campaigners agree. “Increasing SAF production won’t eliminate jet fuel imports overnight,” says Tom Taylor, UK policy manager for lobby group Transport and Environment.

“But by scaling it up, we can shift the source of aviation fuel from geopolitically sensitive fossil fuels to locally managed renewable grids and waste streams.”

That would require investment on a large scale, however, and clearly remains a long way off.

In the short term, meanwhile, dark clouds are hanging over the industry. There seems little prospect of jet fuel prices coming down quickly, and if fears of a shortage prove justified, then the aviation industry and the travellers that rely on it are heading for a turbulent summer.

In most small and mid-sized businesses, Power BI does not arrive as a project. There is no rollout plan, no steering group, no launch. Someone in finance discovers it, finds it instantly familiar, and builds a report.

The report is good. Other people want one. Eighteen months later there are reports everywhere, half the business relies on them, and nobody is in charge of any of it.

I have trained hundreds of new Power BI users over the years, and I see the same light-bulb moment every time. “Oh, this feels like Excel and PowerPoint!” That familiarity is exactly why the tool spreads so quickly, people are not being pushed onto it, they are pulling it into the business themselves. As adoption stories go, that is the good kind. The enthusiasm is real and it is priceless.

But here’s the thing… the same freedom that makes a tool spread is the freedom that creates the mess. Because it grew without guardrails, everyone built things their own way. And a growing business eventually meets the consequences, usually in a meeting.

The day the numbers disagree

The moment this stops being invisible is nearly always the same one. Two people bring two versions of the same figure into the same room. Sales says one number, finance says another, and the conversation that was supposed to be about the business becomes a debate about whose report is right.

It gets called a data problem. It usually is not. Both reports are doing exactly what they were built to do, they were just built by different people, at different times, on different assumptions. One counts orders, the other counts invoices. One strips out cancellations, the other never did. Nobody decided this. It accumulated, one reasonable report at a time.

And underneath it sit the questions that quietly matter more. Who owns these reports? Who fixes the refresh that failed on Monday? Who checked what the new starter can see, and whether the margin data in that shared workspace was ever meant to be visible to everyone with the link? In an unmanaged estate, the honest answer to all of these is usually nobody.

The cost is time, trust and eventually money

None of this shows up as a line on the P&L, which is why it runs for so long. But the costs are real.

Staff time goes first. People rebuild reports that already exist because they cannot find or do not trust the originals. Someone senior spends hours reconciling two dashboards before every board meeting. Then trust goes, and this one is expensive, because once people stop believing the numbers, they stop using the reports and retreat to their own private spreadsheets, and the business is now paying for a reporting tool and running on Excel exports anyway.

And occasionally the cost is sharper than that. A figure nobody can stand behind lands in front of the bank, an investor or an auditor, and the awkward question is not about the number. It is about whether the business is in control of its own information.

The fix is lighter than most owners fear

At this point some owners reach for the opposite extreme, lock it all down, route everything through one person, approve every report. I would gently push back on that too. I have seen over-control fail as often as chaos. Clamp down too hard and people do not stop building reports, they just stop telling you, and the mess moves somewhere you can no longer see it.

For a growing firm, the structure that works is lighter than most people fear. It looks something like this. Every report that matters has a named owner, one person who answers for the figures and one route for fixing it when it breaks. The handful of numbers the business runs on, revenue, margin, active customers, get defined once, in one agreed place that every report draws from, so the same word means the same thing everywhere. Access follows job roles rather than one-off requests and forwarded links. And somewhere, there is a simple, written answer to “how do we do reporting here”, short enough that people actually read it.

That is it. Not a committee, not a six-month programme. Microsoft’s own adoption roadmap covers this ground thoroughly and is genuinely worth a read, I have gone back to it time and time again over the years. But for a small business the heart of it fits on a page. Owners, shared definitions, sensible access, and a bit of support for the people doing the building, because the analyst who taught themselves Power BI is an asset worth investing in, not a risk to be managed.

The stakes are about to get higher

There is one more reason to sort this now rather than later. Power BI is no longer a standalone tool. It now sits inside Microsoft Fabric, Microsoft’s wider data platform, which means the thing your business adopted for reports is increasingly connected to where data is stored, moved and prepared across the company. More capability, and more ways for an unmanaged setup to grow expensive.

This is often the point where firms bring in outside help, and having done a lot of this work, I will tell you what it should look like. When businesses explore Microsoft Fabric consulting in the UK, the first job is usually not the platform at all. It is mapping what already exists, which reports are trusted, which models are duplicated, who owns what, where the access risks sit. Moving a messy estate onto a bigger platform does not clean it up. It gives the mess a bigger stage. Diagnosis first, then the technology.

Boring is the goal

Good reporting in a growing business should be slightly boring. The figures refresh, the definitions hold, people know where to look and stop arguing about whose number is right. The meetings get shorter and go back to being about the business.

The tool that spread through your company without permission got there because it is genuinely useful. That part is a win, and the enthusiasm behind it is worth protecting. It just needs what every useful thing eventually needs, an owner, a shared set of definitions and someone paying attention. The best time to give it those was before it mattered. The second best time is before the platform underneath it gets any bigger.
