It was late 2022. I had just arrived in London with a B2 English certificate, six years of software development experience, and what I thought was solid English. I started applying for jobs. A lot of jobs. And I got rejections. Even more rejections.
It wasn't my technical skills — I'd been writing production code since 2016. It wasn't my visa status. It was something subtler, and it took me almost two years to put my finger on it: my English was good enough to be understood, but not good enough to be taken seriously in a UK professional environment.
The Misunderstanding About English Courses
Most English courses teach you to survive — how to order at a restaurant, how to describe your journey, how to politely disagree. That's useful. But it's not what UK employers are listening for.
In a British office, what matters is different: running a meeting with authority, presenting an idea in a way that lands, giving and receiving feedback naturally, negotiating with a client or your line manager — all with the vocabulary, rhythm, and confidence of someone who belongs in the room. I started calling it professional English. It's a completely different language from what's in any textbook.
The Quiet Problem Many Immigrants Face in the UK
I've spoken to a lot of people in my situation — engineers, developers, analysts from Ukraine, Poland, India, Nigeria, Brazil. The pattern is always the same: strong technical skills, decent everyday English, but professionally stuck well below what their experience justifies.
According to various UK career platforms and industry salary surveys, international professionals in the UK tech sector often earn significantly less than their British counterparts with equivalent experience — not because of their qualifications, but because of how they come across in the room. The decisive factor is usually not what you know. It's how confidently you can communicate it. (Author's own assessment based on personal experience; individual outcomes vary.)

Why Professional English Directly Affects Your Career Trajectory
In many UK companies — especially in tech — the gap between Junior and Senior isn't just a question of years of experience. It's a question of communication. Who can articulate a technical decision clearly to a non-technical stakeholder? Who presents in the all-hands with confidence? Who negotiates their next contract without apologising three times per sentence?
According to salary data from Reed.co.uk and Glassdoor UK, a Junior Developer in London earns roughly £32,000–£45,000, while a Senior Developer typically earns £75,000–£120,000 — that's often two to three times the junior salary.* The technical knowledge alone rarely explains that gap. How you communicate in English is a major part of the equation.
In my own case, the difference between being passed over for promotion and finally having more opportunities than I could handle wasn't a new certification or a new framework. It was the ability to walk into a room and be heard.
"The moment I stopped translating in my head and started thinking in professional English — people started treating me differently at work. Three months later, I had more job offers on the table than I'd had in my first two years combined." — Alex Kovalenko, Senior Developer, London

The Turning Point: A Conversation at a Team Lunch
I was having lunch with a colleague — Maria, originally from Portugal, who had been in the UK for five years. She spoke effortlessly. Not just grammatically correct — she sounded natural, authoritative, the kind of person you'd automatically trust in a client meeting.
I asked her how she'd got there. Her answer surprised me: "Lingoda." I knew the name — an online language school. I was sceptical. I'd already done enough courses. But she was convincing: "It's not a normal course. Real teachers, real conversations, maximum five people per session. They focus on business English specifically."
I decided to try it. I booked the free trial lesson in about five minutes.
My Honest Review of Lingoda
Reviewed after 4 months of intensive Business English training · Rated 4.5/5 "Excellent" by PCMag UK (Editors' Choice, 2025)
What stood out most: I didn't just learn vocabulary — I learned how to negotiate, present, and hold my ground in professional conversations. That's exactly what had been missing from every interview and every meeting where I'd felt invisible.
What Changed — Four Months Later
After four months of consistent Lingoda sessions (two evenings a week, after work), something shifted. I started getting responses to job applications I would have been ignored on before. Recruiters who had previously ghosted me started reaching out. For the first time since moving to the UK, I had options.
I went to three final-stage interviews in one month. I got two offers. The feeling of walking into those conversations — in English, with confidence, knowing I could hold my own — was genuinely different from anything I'd experienced before. I took the role that offered the best growth and, because I could negotiate properly for the first time, came away with better terms than I'd expected. (Personal experience of the author; not representative. Individual outcomes vary significantly.)
Was Lingoda the only factor? Of course not. My technical experience, my preparation, timing — everything played a role. But professional English training gave me the edge that had been missing for three years.
My Recommendation for Immigrants in the UK
If you've moved to the UK and feel like your English is "good enough" but your career isn't moving — I know that feeling. I was there for nearly three years.
My honest recommendation: start with the free trial lesson at Lingoda. No credit card, no commitment. Just one session with a real teacher — and you'll immediately feel whether it's what you've been missing.
I'm not recommending this because I'm paid to. I do earn a commission if you book through my link — but I recommend it because it genuinely worked for me, and for several people I've since passed it on to.*
