To give an idea of where things are going, I’ve been with DroneSafeRegister for the past five years. In the first five months of 2022, nearly 300 people requested quotes for drone work through the site (for the whole of the UK). In the first five months of 2025 there were fewer than 90.
As @PingSpike says, I’m afraid the bottom has well and truly dropped out of the market since the requirement to have a PfCO for commercial work was removed. There are still some people who manage to make a reasonable living from it, but from what I’ve seen they were almost all skilled cinematographers/videographers long before they picked up their first drone, and they established themselves as professional drone operators before 2020 (when the rules changed).
The technology advancements haven’t helped either - even with the rule changes for sub-250g drones and the removal of the PfCO, there was still a bit of a market for those operators willing/able to spend £10k on something like an Inspire 2 with a top-of-the-line lens. But DJI has been blurring the lines between consumer and professional for years so even that market is going - the Mini 5 is going to have a 1" sensor, and in six months you’ll be able to fly an Air3S (or, probably 4S by then) in a city centre with nothing more than a Flyer ID.
I’ve been doing commercial jobs for the last four years. I’ve done roof inspections, residential videos and a little bit of TV work, but the best I’ve managed (and it honestly feels like a success) is to break even at the end of every year (insurance, hardware, software, training, certification renewals, travel… there are more costs than you might think). I would love to be able to say it’s a career, but it’s really a hobby that pays for itself.
Could I have done better if I’d quit the day job and focussed 100% on the drone work? Most certainly. But I don’t think I’d have been able to pay the bills.
If you’re set on being a professional drone pilot I’d echo what’s been said about looking for a job with an existing company. Even if, ultimately, you’re still set on going it alone, this would give you a chance to get the experience with a guaranteed salary (and sick pay, holidays, training, etc).
And with all that said, if you’re still keen on going it alone at least you’re going in with your eyes somewhat open. It will be hard work, but I wish you every success
