HS2, the high speed railway line, is now expected to cost between £87.7 billion and £102.7 billion, and the full line could open up to 13 years later than planned in 2020. Those are the headline numbers from the National Audit Office's latest report, High Speed Two reset, published in June 2026.
It's easy to read the headlines, shake your head and move on. But the report is much more interesting than the numbers. It looks at what happens when a programme outgrows the organization running it, and at what it takes to put things right.
This isn't the first reset, either. HS2 was reset in 2020, Euston was reset in 2020 and 2023, and Phase 2 was cancelled in 2023. So the NAO's message is simple: get it right this time!
I've read the report so you don't have to. Here's where HS2 stands, what's changing, and the lessons I think every project manager can take from it, whatever size of project you're working on.

HS2 is now a London to Birmingham railway, and it's costing roughly twice what was expected in 2020. The Department for Transport (DfT) sponsors and funds it. HS2 Ltd builds it. A new body, Euston Delivery Company, is responsible for the London terminus.
| What | Figure |
| Revised cost estimate (May 2026) | £87.7bn to £102.7bn |
| Increase since 2020, excluding inflation | £35.9bn to £37.2bn |
| Spent so far, including the cancelled Phase 2 | £46.8bn (to March 2026) |
| First services, Old Oak Common to Birmingham | May 2036 to October 2039 |
| Full line, Euston to north of Birmingham | May 2040 to December 2043 |
| Delay compared with 2020 plans | 3 to 13 years |
| Cost of the reset itself | £153m |
| Reset due to finish | Spring 2027 |
Those ranges are wide for a reason. The NAO says the May 2026 estimates still carry a high level of uncertainty. A firmer baseline is due by spring 2027.
Project costs do change, and it’s not uncommon for projects to cost a bit more than the original estimate, especially if there is construction work involved. You don’t have to watch many episodes of Grand Designs before you realize that scope evolves and material pricing changes!
But the HS2 costs have gone up a lot. Inflation explains only about a third of the increase. HS2 Ltd's own analysis splits the £48.6bn rise between the 2020 funding envelope and its current £93.2bn target like this:
| Cause | Share of the increase | What it means |
| Inflation | 34% | Prices rose faster than expected |
| Underestimation | 32% | Building and testing the railway took more time and money than forecast |
| Inefficient delivery | 23% | Poor productivity on the work that was done |
| Scope change | 11% | Necessary work that was missed from the original scope |
The NAO notes it hasn't audited these calculations, so they are HS2 Ltd's view. Even so, two thirds of the increase comes down to estimating and delivery, not the economy. And estimating and delivery is very much in the project manager’s realm of interest.
The reset started in January 2025, and HS2 Ltd's new chief executive finished his review of the programme that March. His assessment was blunt: HS2 Ltd had failed to control costs and schedule, construction had started too soon, contracts weren't delivering, and the organization wasn't set up to manage delivery.
The reset has four workstreams:
All of this is happening while construction carries on. DfT and HS2 Ltd are also working through 124 recommendations from earlier reviews. By February 2026, 45 of them (36%) were done. While that doesn’t sound like many, it probably represents a lot real work happening behind the scenes.
You probably aren't running a £100bn railway, I'm certainly not. But almost everything in this report shows up on ordinary projects too, just with fewer zeros. Here are some of the takeaways I got from the report that could apply to your work too.
The chief executive's review found that construction had started too soon. Once work is under way, the pressure to keep going makes it much harder to fix the plan. The NAO's top recommendation follows the same logic: don't put the revised plans into action until everything is in place to deliver them.
Try this: Before your next phase starts, ask what you're still assuming. If the answer is "quite a lot", that's a conversation for your sponsor now, not three months in.
When Phase 2 was cancelled, the organization didn't adjust to the smaller programme. HS2 Ltd's own review found too many people at the centre and too few in front-line delivery teams. It also found silo working, gaps in commercial and contract management skills, and an over-reliance on complex processes.
Try this: After any big change to scope, look at your team structure, not just your plan. Does the way you're organized still match the work?
The same review flagged a lack of trust in the integrity of data. A baseline is only useful if people believe the numbers in it. HS2 Ltd is now testing the quality of its data and assumptions before it sets the new baseline.
Try this: Ask your team how confident they are in the figures in your status report. Their answer tells you a lot!
HS2 Ltd tried to renegotiate its big contracts in 2024 and failed. It didn't have a reliable estimate of total cost, didn't understand the supply chain's work well enough, and offered a risk-transfer deal contractors didn't want. Second time round, it settled historic costs first and found around £500m of costs it won't pay. It's now aiming to save around £2bn.
Try this: Before you go back to a supplier about a contract, make sure you know what has actually been spent and why.
The trains will now run at 320 km/h instead of the planned 360 km/h. That means a simpler train control and signalling system and less testing, saving an estimated £1bn to £2.5bn. The line could also open at least a year earlier, although this is a multi-year project so it probably won’t feel like much of a time-saving to the people on the front line. The trade-off is around £1.3bn in lost long-term benefits from slower journeys.
Try this: When a requirement carries a lot of risk, ask what the "good enough" version would cost and what you'd give up. Then let the sponsor make the call with both numbers in front of them.
The Stewart Review found HS2's governance wasn't fit for purpose. It also said trust between DfT and HS2 Ltd needed to be restored. New boards and a ministerial taskforce help. But the NAO also found a more collaborative way of working, and HS2 Ltd says new decision-making for mega-projects has cut decision times by reducing duplication.
At Euston, the earlier problem was that no single body had the authority to make trade-offs. The fix is a new company acting as the "single directing mind".
Try this: For every big decision on your project, can you name who makes it? If not, sort that out before you need it.
DfT says that, had today's costs been known in 2020, HS2's benefit–cost ratio would have been 0.3 to 0.4. That's "poor value for money". Continuing now still makes sense because the money already spent doesn't count in that sum.
Sunk cost fallacy, anyone?
The NAO says DfT must focus hard on getting the most value from what it's spending, and set out who owns, delivers and reports the benefits.
Try this: Check your business case is still valid at every stage gate, not just at the start. And make sure someone owns the benefits once the project closes.
The next few months are going to be busy for this program team! HS2 Ltd expects an initial version of the new baseline in autumn 2026 (at the time of writing, so that’s any time now) and the final version by spring 2027. The main contract renegotiations are also due by autumn 2026, about six months later than planned.
HS2 Ltd is also assessing its capability across 10 core areas, including project management, program controls and integration, so it can close the priority gaps by spring 2027.
So what do I think? The NAO's verdict is fair but firm – they are known for this, and in past reports I’ve read they don’t hold back. They are very good at speaking truth to power!
DfT and HS2 Ltd are taking a considered approach, but there's a lot left to do. The report recommends they check whether the spring 2027 deadline is still realistic, and take more time if they need it.
It’s so important to take the time you need. A reset that's rushed to hit a date is just the start of the next reset… although we all know this is a difficult message for stakeholders who want everything yesterday!

If you want to certify as a PMP before the exam requirements change, you've just about got time.
I believe it takes 8-12 weeks to comfortably prep for the exam so if you are committed and prepared to put the effort in, you can squeeze in your exam.
So what's changing?
You will only be able to claim the 35 contact hours of training for live courses if the live course is taught by an accredited provider.
Also, and this is a big one...
I think live learning under the new scheme will cost more.
Currently, pretty much any training that covers PMP-related topics can count towards the requirement for 35 contact hours. From the end of 2026, it will only be Authorized Training Partners (ATPs), or a China Registered Education Provider (REP), or be covered under the academic recognition scheme.
That means any organization currently teaching live PMP prep courses will have to register as an ATP (which I've heard from trainers is a long and expensive process), or market their courses as not covering the 35 hours requirement (which makes them less attractive to students).
There are no changes to the eligibility of self-paced courses. So if you plan to study with Brain Sensei (my recommended PMP training course), then you're still good.
This change only affects live training, so unfortunately, if you are someone who learns better with the support a live instructor and a classroom environment, then try to get your application in as soon as you can!
The hybrid option is the Brain Sensei AI-powered course, which has an AI "instructor" you can ask questions to, use voice commands with and interact with as if you were with a mentor.

Are you here because you've heard the

And what do the new training eligibility requirements mean for candidates when these come into effect later in 2026? Read on...
Every so often PMI carry out an assessment of what a project manager does all day. This is done by carrying out a Job Task Analysis, where PMI analyzes the standards and industry practices globally so the exam and the exam content outline can be updated to accurately reflect the job.
In other words, PMI (or more specifically, the agency contracted to do this work) look at what a project manager actually does day-to-day and link this back to the certification. If they didn't, you'd find that the
This latest analysis from PMI has shown, as is to be expected, that the project manager's role has evolved. Plus PMI want to put more emphasis on emerging trends like AI and sustainability. The exam is being updated to reflect that.

After the July 2026 update, we don't know when the exam will change again. It was last updated (I think, from memory) in 2021 so this version will be valid for around 5 years I'd guess. If there is a release of the
PMI do update the exam every few years so it stays relevant, so it is likely there will be changes in the future. But right now, you're good to go.
The new
As you can see, the exam content looks similar to the previous current exam content outline, where the knowledge domains are basically the project lifecycle.
Each new domain is made up of a number of tasks (in the same way the old exam content outline was), with enablers that are illustrative examples of the work.
Questions across the
People:33% (was 42%) -- not sure I'm in agreement with this, I'd say people were even more important these days
Process: 41% (was 50%) -- I'm personally happy about this, it represents the fact that we are less wedded to the 'ideal' way of doing things and those process questions were tough as they rarely reflected what project managers would actually do at work in my view
Business environment: 26% (was a pitiful 8%)
The traditional take on project success is that metrics like schedule, budget and scope defined whether or not our projects made the grade. In the new PMI exam, the definition of success has broadened out (a good thing).
PMI says that this broader perspective takes stakeholder value and accomplishment of the desired outcomes into account when defining success. In other words, success is when you deliver something of value that was worth the effort and expense. It's still a version of the iron triangle, but it's more aligned to how senior leaders think about the business value and ROI for projects.
The question formats have changed to be more interactive, so that should make taking the exam feel like a more modern experience. There are more scenario-based questions (which means more reading in the exam).
In October 2026, an exam simulator producer contacted me to say that his PMP students were telling him that all the exam questions are now scenario-based. I haven't verified that myself, but it seems sensible to assume that you'll be doing more scenario-type questions in exams from now on.
The amount of time available in the exam is still the same. You still have 180 questions to answer in 240 minutes, and they reflect what PMI calls 'real project environments' so that should be good.
And, the amount of
This is where the next big change is.
PMI states that today's project managers work across projects taking place in a variety of environments. As such, the exam needs to reflect the "value spectrum" (whatever that is) encompassing predictive,
In other words, expect to see situational questions on the exam that are set in each of those types of environment. Questions on each environment are included in the three exam domains.
However, previously, the exam covered both predictive (approximately 50%) and

Meanwhile, practicing with an exam simulator is still my preferred option for getting exam ready.
Late Q4 2026, PMI is updating the live training eligibility requirements. This means that after the date of the change, your 35 contact hours of training will only count if your live training is delivered by a:
Any provider who falls into this category will be clearly advertising their services as such, so if you can't see the authorization on their website, assume that they are not registered with PMI.

The changes might feel like a big change at the moment, but hopefully in time they will feel like a natural evolution of the role. Take some practice exams to build your confidence and then go for it! Good luck!
