In the UK, standard outdoor taps (spigots) and garden hose accessories almost universally use 3/4-inch BSP (British Standard Pipe) threads.
How to verify: Measure the outside diameter of the male thread on your tap or existing hose connector using a tape measure or ruler. A standard 3/4-inch BSP thread will measure approximately 26.5 mm across the outer diameter (despite the "3/4 inch" name referring to an older nominal bore size).
