Best 4 in 1 boiling water taps 2026: 8 models compared on price, filter and running cost
A 4-in-1 tap replaces both the kettle and the cold filter jug: boiling, filtered cold, plus ordinary hot and cold from one spout, so it goes in place of your existing mixer rather than alongside it. This list covers every 4-in-1 model in our library, ranked by price, lowest first.
A 4 in 1 boiling water tap gives boiling water, filtered cold water, and ordinary hot and cold water from one spout, in place of your existing mixer. We list 8 current models, from £399 to £1,249 RRP. The cheapest is the Hanstrom Saxan 4-in-1 at £399. Tanks hold 2.4 to 7 litres, and the filter cartridge is a running cost on top of the price.
A 4-in-1 boiling water tap is one spout system that gives boiling water, filtered cold water, and ordinary hot and cold water. The filtered cold water usually has its own channel next to the boiling one, which is why the label counts four. We list 8 current 4-in-1 taps from 5 brands, with recommended retail prices from £399 to £1,249.
The range is wide on price and narrow on size. Tanks hold 2.4 to 7 litres and the maximum temperature runs from 98 to 100°C. All of them carry a filter. The cheapest is the Hanstrom Saxan 4-in-1 at £399 and the most expensive is the Abode Pronteau Province 4-in-1 at £1,249.
Temperature control differs per tap. Hanstrom Saxan 4-in-1, Fohen Focetti Pro 4-in-1 list temperature presets, so a cup of green tea does not need water at 98°C. Check the spec table on a model page before you buy, because 98°C and 100°C are different products: the label says 4-in-1 either way.
The label is a count of functions, not a quality grade. Taps with chilled and sparkling water are 5-in-1 or 6-in-1 hubs and sit above this table. A 4-in-1 replaces your mixer, so it needs a hole in the worktop or sink, a tank under the sink and a power socket. A dedicated hot water tap that sits beside your existing mixer is a different install.
Running costs sit on top of the RRP. The tank draws power while it holds water hot, and the filter cartridge is a recurring purchase. The running cost calculator turns a tap's idle wattage and your tariff into a yearly figure, and the filter cost calculator does the same for cartridges.

Questions people ask
- What is a 4-in-1 boiling water tap?
- A tap that gives boiling water, filtered cold water, and ordinary hot and cold water from one spout system. The filtered cold water normally has a separate channel next to the boiling one.
- What is a 4 in 1 tap?
- Short for a 4-in-1 boiling water tap: one spout that delivers boiling water, filtered cold water, and ordinary hot and cold water. The label counts functions, not quality, so compare tank size, maximum temperature and warranty as well.
- 3 in 1 or 4 in 1?
- Choose a 4 in 1 if you want filtered cold water from the same spout and accept a filter cartridge as a running cost. Choose a 3 in 1 if you only want boiling, hot and cold water, because it avoids the cartridge. The 3-in-1 vs 4-in-1 vs 5-in-1 guide sets the three side by side.
- How much does a 4-in-1 boiling water tap cost?
- Recommended retail prices in our library run from £399 (Hanstrom Saxan 4-in-1) to £1,249, across 8 current models.
- How big is the tank in a 4-in-1 tap?
- Tanks in our library hold 2.4 to 7 litres. The tank sits under the sink, so measure the cabinet before you order.
