My bad, retraction on prior statement of the next season being already filmed. I read something a while back and probably misinterpreted it. They contracted with Netflix for two seasons. This one and another.
Here's some further details.
Is there a Top Boy season 4 on Netflix?

When will Top Boy be back on Netflix?
While Netflix is no stranger to releasing series like clockwork on an annual basis, the two-year wait between the seasons shown on Channel 4 may foreshadow a comparable timeframe to allow for Bennett (who’s written every single episode thus far) to maintain the established level of quality expected from Top Boy.
On the other hand, the aforementioned season three is the result of a six-year wait, so season 4’s outline may already be finalised due to the revival’s wide praise. In that event, the earliest they can release it is around a year after they start shooting. The problem being we don’t know when that’s scheduled to be!
Will it be the last series?
Netflix
The only information we have is that Top Boy was resurrected by Netflix for two seasons, with the first being recently released and the second’s release date still not officially confirmed.
Given that the streaming service hasn’t explicitly said that season four will be the last, that strongly implies that a fifth season will be commissioned. The other thing to consider is that Netflix has always been hesitant to reveal viewing figures for their content, so we’re yet to know how pleased they are with the most recent outing: season three."
Top Boy season 4 - what has Netflix said and how does series 3 end?

Will there a fourth series of Top Boy?
Top Boy's showrunner Ronan Bennett has confirmed that he’s currently in talks with Netflix regarding a second series under the streaming giant.
In an interview with
Metro, he revealed: “We want to do a new season and we’re talking to Netflix about it.”
Ronan went on to discuss how working on the new season of Top Boy was an incredible experience, adding that all of the ideas and concepts turned out exceptionally well.
It's not common that ideas and concepts written on paper can translate so effortlessly well on screen, but given his own words, it seems Ronan has found his dream team, who truly understand the core message of the drama.
“We’re incredibly proud of what we’ve all achieved with the new season," he gushed.
“Sometimes you write something for screen and it just doesn’t come out as well as you’d hoped even though all the individual parts are good, but somehow when they’re all together they just don’t gel. This is different.”"
