“How many lessons will it take?” is the question everyone wants answered before they book, and the honest reply is the one nobody likes: it depends. But that’s a cop-out unless someone gives you real numbers to work with — so here they are. Moving up a full CEFR level, say from B1 to B2, is a measurable amount of work, and once you know roughly how much, you can plan it, budget it, and stop guessing. The good news for anyone weighing up private lessons is that one-to-one is the fastest route there. Let’s look at why, and at how many lessons you’re actually talking about.
The real answer is in hours, not lessons
Language levels aren’t measured in lessons — they’re measured in guided learning hours, and the most widely used estimates come from Cambridge and the Council of Europe. As a rough guide, it takes somewhere around 150 to 200 hours of focused study to climb one CEFR level in the middle of the scale. The lower levels move quicker; the higher you go, the longer each step takes. Getting from A1 to A2 might cost you 100–150 hours, while the jump from B2 to C1 can swallow 200 or more. That’s not because you get slower — it’s because each level asks more of you than the last.
Two things matter here. First, “guided hours” means time spent actually learning with structure, not just watching films with the subtitles on. Second, these are averages. Plenty of motivated adults move faster, and a few take longer — and both are completely normal.
Why one-to-one lessons get you there faster
This is where private lessons earn their price. In a group class of ten, you might speak for five minutes in a sixty-minute lesson. In a one-to-one lesson, every one of those sixty minutes is yours. The teacher isn’t pitching to the middle of the room — they’re working on your weak spots, your pronunciation, the exact grammar gaps standing between you and the next level. That’s why a single hour of focused private tuition often does the work of two or three hours in a group.
It changes the maths completely. If a level takes 200 guided hours in a general group course, a well-run one-to-one English course can cover the same ground in far fewer, because none of your time is wasted waiting for your turn.
So how many lessons is that, really?
Let’s make it concrete. Say you’re at a solid B1 and want a confident B2, and you take two one-to-one lessons a week. Between lessons you do the homework and practise for an hour or so on your own. At that pace, most learners see a genuine level shift over roughly four to six months — call it 40 to 60 lessons — with real, visible progress along the way, not just at the finish line.
Want it faster? Three or four lessons a week compresses that same journey into two or three months. Prefer a gentler pace? One lesson a week still works — it just stretches the timeline out. The total workload barely changes; what changes is how you spread it. This is exactly why so many people search for a “one to one English course” in the UK when they have a deadline — a visa, a job offer, an exam date — because the private format lets them turn the intensity up.
What actually decides your speed
The hour estimates assume an average learner doing average practice. Four things move you off that average, in either direction. Your starting point matters — the higher your level, the slower the climb. Consistency beats intensity: two lessons a week for six months will always beat a frantic burst followed by three weeks off. What you do between lessons matters enormously — the learners who progress fastest treat homework as non-negotiable. And a clear goal focuses everything; “pass IELTS 6.5” pulls you forward far harder than “improve my English.”
Notice that three of those four are within your control. Your teacher sets the direction, but the pace is mostly yours to set.
If you want a straight answer for your own situation, the best move is a quick level check and an honest conversation about your goal and your deadline — from there, the lesson count almost works itself out. That’s how we plan every private programme at Kensington English: we find your level, agree on where you want to be, and build a realistic path between the two. Tell us the deadline, and we’ll tell you the lessons.
