You already speak English.We make you sound like the person who should be running the meeting.
English built around one profession at a time — for people who are fluent enough to do the job, and lose ground the moment the meeting gets difficult.
20 minutes, no charge, no obligation. You leave it knowing exactly where your English gives way.
What actually goes wrong
It isn't vocabulary. It isn't grammar.
At B2 and C1 the things that cost you are not the things a general English course teaches. Four of them, and every one is trainable.
- 01
Retrieval speed
You know the word. You cannot reach it in the 1.2 seconds a live meeting gives you, so you say something adjacent and weaker.
- 02
Register control
Your English is correct and it lands blunt, or cold, or junior, or evasive. Nobody tells you. They just respond differently to you than to the person next to you.
- 03
Professional pragmatics
Disagreeing with someone senior. Escalating without blaming. Hedging a forecast. Chasing a non-responder for the fourth time and still being pleasant about it.
- 04
Domain collocation
Not escalate. Escalate to second line. The half-sentence that tells a listener you have done this job before.
You are not trying to learn English. You are trying to stop being the least persuasive person in the room.
Principle 3 · Register before rules
Both of these are perfect English.
One of them loses the client. At your level, the error that costs money is almost never grammatical — it is tonal. So we drill the distance between blunt and deferential until you can choose it deliberately.
The situation
A supplier owes you a file today. You have asked twice already. They are more senior than you, and you need this without damaging the relationship.
“Could you get that over to me today?”
- How it lands
- A request that leaves them room, and still names the day.
- What it costs you
- This is the one that works most of the time, and the one most learners never reach under pressure.
Four rungs, one ladder, nine of them in the course. Learners arrive able to recognise the difference and unable to produce it on demand. That is the gap the course closes.
Sixteen professions
The course is built around your job, not around a coursebook.
Every profession gets its own vocabulary, its own scenarios, and its own professional acts. Open one and look inside — the samples below are taken from the actual course.
One lesson, ninety minutes
Every lesson ends with you doing the thing.
Not knowing about it. Doing it — under time pressure, unrehearsed, with someone pushing back. The seven stages run in this order every week, so you always know where you are.
1Retrieval warm-up
10 minLast week's language, cold, before anything new. Retrieval is what makes it stick.
2Authentic input
15 minA real genre from your profession — the email, the call, the report — read or heard as it actually occurs.
3Lexis & collocation
15 minNot words. Chunks, with the collocation and a sentence showing the word doing its job.
4Register & pragmatics
15 minThe ladder. Same content, four distances, chosen on purpose.
5Production under pressure
20 minTimed, unrehearsed, with a consequence. No notes, no preparation. This stage is never cut.
Never cut
6Feedback & error log
10 minWhat you actually said, written down by you, with the teacher. Three strikes turns a slip into a pattern.
7Field Task
5 minThe week's work set and explained. Thirty minutes, and half of it happens at your desk at work.
Between sessions
Thirty minutes, and we do not call it homework.
You are a working professional paying for a professional service. The word imports a school relationship that has no place here. It is a Field Task, and the second half of it happens at your actual job.
Part A without Part B is a language exercise. Part B is the course.
Part A · At your desk
20 minutesWritten consolidation — the collocations, the ladder rewrites, a draft of the week's genre. Every item has an answer key.
Part B · At work
10 minutesUse the week's professional act in your real job, once, this week. Then write two lines: what you said, and what happened.
Reviewed aloud in the next lesson. Never collected, never marked — no Windsor course promises marking, and no teacher spends their evening pretending otherwise.
Principle 2
Your own work is the syllabus.
Once the course is running, you bring a real email, deck or ticket from your own working week, and the room works on it. It is the single hardest thing for a competitor to copy, and the main reason corporate clients renew.
Anonymised before it leaves your office
Every name, employee number, salary figure, address and email is removed by you, at work, before it comes anywhere near the classroom. You bring the situation, never the file.
On a published rota
Everybody takes a turn and everybody knows when theirs is. Nobody is put on the spot, and nobody quietly avoids it for eleven weeks.
Three formats
One course, compiled at the length you can commit to.
Not three different products. The same authored material, compiled to twelve, sixteen or twenty-six lessons, with the specialist areas unlocking as the course gets longer.
Short Course
Core areas
12lessons
18 contact hours
The essential professional acts of your role. The easiest one to get signed off by an employer.
Intensive
Core + extended
16lessons
24 contact hours
Adds the standard professional scope around the core. The usual choice for a competent B2.
Full Semester
Everything
26lessons
39 contact hours
Adds the specialist, senior and compliance-facing areas. A real commitment, and the one that changes how you are heard.
Two courses — Call Centre and Career & Interview English — stop at sixteen lessons. That is by design, not an omission: neither has a specialist tier worth a further ten weeks of your evenings.
Groups of four to eight
Below four, the multi-party tasks stop working. Above eight, speaking time per person drops below what the fee justifies, so we split the cohort rather than take the extra learners.
On-site at Krupnicza 14 in Kraków, or online.
Closed cohort
One employer, one team. Tasks can name your company's actual processes, and the room already shares the context.
Open cohort
Mixed employers, enrolled individually. You hear how a different company handles the same escalation — that cross-company exposure is a selling point, not a compromise.
One-to-one tuition is available as a priced premium option.
Class size 4–8.
Where everyone starts
Twenty minutes, free, and useful even if you never enrol.
A structured conversation with someone who knows what they are listening for. No test paper, no multiple choice, no score read out at you.
You get your level in writing afterwards, next to a recommendation — never as a verdict said out loud across a table.
Book your placement1Warm-up
Three minutes to settle. Nothing here is assessed, and we say so.
2Your current role
Six minutes describing what you actually do. Most placement happens here.
3The difficult part
Eight minutes of argument and hypothesis — and one moment where we disagree with you on purpose. What comes back is the most informative thing in the conversation.
4Your own account
Three minutes on where your English fails you. Usually the most useful three minutes of the twenty.
For employers
A closed cohort for one team, built around what that team actually does.
Kraków's shared service centres run in English all day and train in generic business English. We build the course around your processes, take four to eight people at a time, and hand your L&D team documentation they can audit.

Why this exists
Kraków runs on English. The shared service centres, the software houses, the law firms and the finance teams all operate in it every day, and most of the people doing that work are operating in their second or third language at a level that is genuinely good.
What they are sold is general business English — a coursebook, a mixed-ability group, and a syllabus that would be identical in Lisbon or Manila. It is not that it fails. It is that it stops being useful somewhere around B2, exactly where the real problems start.
Windsor was built around the opposite assumption: that at B2 and C1 the thing holding you back is specific, professional and trainable, and that a course is only worth your evenings if it can name what that thing is on day one.
Why it holds together
We are new. So here is the thing you can actually check.
No testimonials, no client logos, no completion statistics — we have not been running long enough to have honest ones, and inventing them is how a school gets caught. What we can show you is how the courses are built.
- 30documents per course
- Teacher pack, teaching guide, answer key, field-task key, learner handouts, field tasks, slides, appendices, placement test and learner forms — compiled from one source, at each of the three lengths.
- 420vocabulary terms
- Each with a definition, a collocation, an authentic example sentence, and Polish, Ukrainian and Russian. A term without a collocation is treated as incomplete.
- 100%keyed and scripted
- Every exercise ships with its answers. Every listening ships with a full transcript. Every lesson ships with a runsheet a fluent non-specialist could teach from cold.
- 0teacher notes reaching learners
- An automated check derives its own tests from the source material and asserts that no teacher-only sentence survives into anything a learner sees. It runs before anything leaves the building.
Before you ask
The questions everybody asks first.
What level do I need?
B2 or C1 — comfortable in English day to day, losing ground when it gets difficult. Below that, a general business English course will serve you better first, and we will tell you so rather than take the booking. Above C1 there is often nothing here worth your money, and we will say that too.
How big are the classes?
Four to eight. Below four the multi-party tasks stop working; above eight nobody gets enough speaking time to justify the fee, so we split the group instead.
Can we do it online?
Yes, and the course is built for it rather than adapted to it. Groups run on-site at Krupnicza 14 in Kraków or online — including for learners elsewhere in Europe.
How much homework is there?
None, because we do not set homework. There is a Field Task each week: thirty minutes total, twenty at your desk and ten inside your actual job. It is reviewed aloud in the next lesson and never collected.
My English is fine. My team's isn't.
Then the conversation to have is about a closed cohort — one team, one employer, tasks built on your own processes. Start with the employers page.
What does it cost?
It depends on the format, the cohort and whether you are enrolling yourself or a team, so quoting a single number here would be misleading. The placement conversation ends with a recommendation and a price for it.
Do I have to bring work from my job?
Yes, once, on a rota you can see in advance — and anonymised by you before it leaves your office. You bring the situation, never the file. It is the part of the course learners rate highest afterwards and dread most beforehand.

Book the placement. Decide afterwards.
Twenty minutes on the phone or across a table. You will leave it knowing exactly where your English gives way — and that is worth having whether or not you enrol with us.
