RRPs come from Qettle and exclude installation. Running cost adds the electricity to keep the tank hot all year (idle draw times 24 hours times 365 days) and to heat 10 cups of 0.25 litres a day from cold to boiling, at 27p per kWh.

What a Qettle is, going by the data

The names carry a 4-in-1 label, which Qettle uses for a tap that gives boiling water at 100°C and filtered water. Our data lists no chilled or sparkling water on any Qettle, so do not read the label as a chiller and a carbonator. The class guide explains what the labels cover across brands. All 4 models list a 2 year warranty and are available in more than one finish, which each model page lists.

Original, Signature and the Modern range

The Qettle Original 4-in-1 is the entry point at £620, with a 4 litre tank and a 14 W idle draw. The Qettle Signature costs £795 and has a 2 litre tank, the smallest in the range, which suits a small kitchen. The Modern taps come in two tank sizes: the Signature Modern 4-in-1 (4L) at £870 with 4 litres, and the Signature Modern 4-in-1 (Round Spout, 7L) at £945 with 7 litres and a round spout.

Tank size is the real choice. A larger tank gives more cups before the tap has to reheat. It also keeps more water hot while you are not using it: the Qettle Signature Modern 4-in-1 (Round Spout, 7L) draws 18 W idle and costs £68 a year to run, the highest on the page. Across the range the idle draw runs from 11 to 18 watts, so the yearly running cost runs from £51 to £68 on the rule our running cost calculator uses. Pick the smallest tank that covers how many cups you pour in a row.

Qettle vs Quooker

The cheapest Quooker in our library is the Quooker Classic Nordic Round Single Tap at £1,050 RRP, with a 3 litre tank, a 10 W idle draw and about £49 a year to run. It lists no filtered water. Every Qettle is cheaper: the dearest one, the Qettle Signature Modern 4-in-1 (Round Spout, 7L), is £105 below it, and the entry model is £430 below. What the price gap does not tell you is service and build, which our data does not measure. The side-by-side with prices, warranty and ten-year cost is on Quooker vs Qettle, and the wider field is on Quooker alternatives.

Who each Qettle suits

Choose the Qettle Original 4-in-1 if the price matters most and one filtered boiling tap is all you want. Choose the Qettle Signature if the space under the sink is tight. Choose a Modern tap if you want a different spout style or a larger tank, and take the 7 litre version only if you pour many cups in a row, because it costs the most to keep hot. Every model on this page has the warranty stated in the table, so read it next to the price before you decide.

Questions people ask

How much does a Qettle boiling water tap cost?
The 4 Qettle taps in our library list at £620 to £945 RRP. The cheapest is the Qettle Original 4-in-1 and the dearest the Qettle Signature Modern 4-in-1 (Round Spout, 7L). RRPs come from the maker and exclude installation.
What does Qettle 4-in-1 mean?
Qettle uses the label for its filtered boiling taps. In our data every Qettle lists boiling water at 100°C and filtered water, and none lists chilled or sparkling water, so it is a different thing from the 4-in-1 taps that add a chiller and a carbonator.
Which Qettle has the biggest tank?
The Qettle Signature Modern 4-in-1 (Round Spout, 7L), at 7 litres. The smallest tank is 2 litres on the Qettle Signature. A bigger tank gives more cups before the tap has to reheat and draws more power while it waits.
Is a Qettle cheaper than a Quooker?
On RRP, yes. The cheapest Quooker in our library lists at £1,050, which is £105 more than the dearest Qettle. Our data does not compare build quality or service, and the warranty on the Qettle taps is 2 years.
