Garden hose fittings in the UK typically come in standard sizes to ensure compatibility and ease of use. The most common size for UK garden hose fittings are: 1/2 inch (13mm) but in some large gardens you may find 19mm hose which requires the 3/4 inch(19mm)connector. Brands are normally interchangeable and will all click together although if you come across any leaks we would advice sticking to the same brand.
To attach a hose to a garden tap which has a thread you will need a tap adapter which will normally be 3/4 BSP. For help identifying your tap size take a look at our blog Garden tap thread size.
