R,

Domestic heating oil in the UK is known as 28 second and sometimes refered to as kerosene. There is now a premium grade available as well.

In NATO specs, what is known a 28 sec. Regular heating oil, is specified as NATO F-58 and British DEFSTAN as KERO/B Kerosene BS 2869 Class C2

Premium grade 28 sec heating oil is equivalent to DEFSTAN KERO/A , Kerosene BS 2869 Class C1. This one is not classified in NATO.

With the Blue Book (DEFSTAN), you will see the full spec.
