Colthrop is a village in the town of Thatcham in the English county of Berkshire, England.

The settlement lies on the A4 road, and is the location of numerous industrial parks and haulage depots due to the area's proximity to Thatcham railway station.

The industrial area was previously the site of the Colthrop paper mills.

Its aim is to reduce or contain the cost of motor insurance claims in the UK whilst maintaining safety standards.

[3] The 'Thatcham categories' issued by the centre for vehicle immobilisers and alarms have become an industry standard since their launch in the 1990s.
