I've just checked my postcode on Uber Eats, but its site comes up with nothing locally. I'm not familiar with it, but I assume (and correct me if I'm wrong) that it would require an existing Uber presence in the area. I've just checked Deliveroo and similarly there are no local results.
Just Eat has been around here for a couple of years now, with several outlets listed. Living in a village a few miles outside of town, it certainly offers me a better choice for take-away. In the village we have a chippy and a Chinese that close at 8.30 and 9pm respectively, and now I can enjoy a kebab or pizza after closing time like anyone else.
Understandably, I still have to pay a few quid for delivery, but the charges aren't so bad if a few people are ordering. There is the added benefit that those outlets who aren't using the platform are now finding that they have more competition and have either lowered their own delivery charges, or have begun to deliver to areas that they previously didn't serve.
Drivers seem to be a mix of self-employed couriers and taxi drivers who might otherwise be having a quiet night.
