Meera Malik's kitchen (supposedly in the UK) doesn't look British. In particular, the electrical sockets at the end of the worktop (counter) are clearly American.
The car outside the building Raymond & Syia run from has the wrong number plates for the UK.
In the opening scene, the car number plate format is wrong for the UK. Also the street signage is wrong for the UK - the "T" dead end / no through road sign should be a straight square, not rotated 45 degrees, and it would refer to the road it is posted on, not a road off to the left.
A British person would likely never refer to 'blocks' when giving directions, even in Milton-Keynes which is the only UK town that is deliberately grid based.
