London has more Power BI training options than any other UK city, which is good news if you can compare them honestly and bad news if you cannot. Prices vary by an order of magnitude, course quality varies even more, and the right format depends almost entirely on what you are actually trying to achieve. Here is a comparison from someone who has both attended and delivered most of them.
The four formats worth considering
1. Public scheduled courses. Open to anyone, run in a London training centre or via Teams, usually 2–3 days. Providers range from QA, Learning Tree and Firebrand to smaller specialists. Typical price: £900–£2,000 per delegate for a three-day course. Good for individuals from organisations that only need one or two people trained. Less good for teams, because the syllabus is generic.
2. In-house bespoke training. A trainer comes to your office (or runs it on Teams) and teaches your team on your actual data. 2–3 days for an introduction, 1 day for a focused intermediate topic. Typical price in London: £1,200–£2,000 per trainer day, so £2,500–£5,000 for a small in-house course regardless of group size. Best value once you have four or more people to train, and the only format where the content reflects your real reporting needs.
3. On-demand video. Pluralsight, LinkedIn Learning, SQLBI's DAX courses, Microsoft Learn. Costs range from free to about £400 per year. Excellent for self-motivated individuals who want depth on a specific topic (DAX, M, modelling) and have time to work through it. Useless for organisations who need a consistent baseline by next month.
4. Certification preparation. Targeted at the PL-300 (Microsoft Certified: Power BI Data Analyst Associate) exam. Usually 4–5 days, costs £1,500–£3,000 with the exam voucher bundled. Worth it if certification is required for a role or procurement, less worth it if you actually want to build production reports.
What to expect from each
Public scheduled courses are convenient but the syllabus is usually the same Microsoft-aligned content delivered by a rotating cast of contract trainers. Variability of trainer quality is the main risk. Ask in advance who is delivering and whether they have hands-on consulting experience.
In-house training is almost always better value for teams of four or more. The trainer can spend day one on your actual data sources, day two on the exact measures and visuals your reports need, and day three on the questions your team keeps getting stuck on. By Friday, four people know how to do the same things the same way — which is the actual goal.
On-demand video shines on depth. SQLBI's "Mastering DAX" is the best couple of hundred pounds you can spend if DAX is the thing holding you back, and Microsoft Learn is genuinely strong for the breadth of the platform. The catch is that it requires time and discipline. We have seen many enterprise video subscriptions where logins go unused after week three.
Certification courses are well-defined and predictable, which is what makes them useful for procurement and HR. They are also narrower than they sound — PL-300 covers a useful subset of Power BI, not the full picture, and passing it does not mean someone can build a production dashboard.
Realistic London prices in 2026
Per-delegate costs for the most common options:
Three-day intro public course at a national training provider: £1,200–£1,800.
Three-day intro bespoke in-house course (whole team): £3,500–£5,500 total. Past four delegates, this is cheaper per head than the public equivalent.
PL-300 certification bootcamp: £1,500–£2,500 including exam voucher.
Annual on-demand subscription (Pluralsight, LinkedIn Learning): £200–£400 per user per year. SQLBI standalone DAX bundle: roughly £350 one-off.
Half-day mentoring follow-up sessions (sometimes the best money of all): £600–£900 per session.
The mistake almost everyone makes
Training is treated as a one-off event. People attend a three-day course, return to the office, and within two weeks most of it has faded. The pattern that actually works is compressed teaching followed by spaced reinforcement. A three-day intensive course, then a half-day mentoring session a fortnight later, then another after a month. Total cost is not much more, and the team still knows what they were taught six months on.
The other common mistake is training too early. If your team does not yet have access to the data they will eventually report on, a generic Power BI course on the AdventureWorks sample dataset will not stick. Sequence training so it happens when there is real data to apply it to.
How to choose
One or two individuals, no urgency: public course, plus a cheap on-demand subscription for depth afterwards.
A team of four or more, ramping up together: bespoke in-house training on your data, with mentoring follow-ups baked in.
Need certification on the CV: a PL-300 bootcamp followed by practice exams. Do not assume it teaches you to build real reports.
Already using Power BI but want to be sharper at DAX, modelling or performance: SQLBI's specialist courses, video or in-person, beat almost everything else.

Frequently asked questions
How much does Power BI training cost in London?
Public scheduled courses run £1,200–£1,800 per delegate. Bespoke in-house training for a team runs £3,500–£5,500 in total and works out cheaper per head past about four delegates.
Is Microsoft's free Power BI training enough?
Microsoft Learn is excellent for individual self-study and covers the breadth of the platform. It is not a substitute for a structured course when you need a whole team to be at the same level by a deadline.
Do I need the PL-300 certification?
Only if a role, procurement process or employer specifically requires it. Many of the best Power BI practitioners in the UK are uncertified — certification is a signal, not a competence.
