Yes, drones under £200 are worth buying if you want a beginner drone for practice, simple photos, and short casual flights. This price tier is strongest when the model includes GPS, Return to Home, spare batteries, and a camera that is actually stable enough for daylight footage.
The trade-off is that a £200 ceiling still limits the camera, stabilization, obstacle sensing, and reliable long-range control. If two models look similar, choose the one with better flight stability, clearer battery workflow, and stronger GPS/RTH support rather than the one with the biggest headline resolution number.
Drones under £200 are weaker choices if you need smooth cinematic video, dependable flying in wind, long transmission range, or advanced safety sensors. They are better as learning and hobby drones than as serious camera drones.
