A 3 way kitchen tap UK households can fit without a second hole
Upgrading to a premium 3 way kitchen tap uk households can fit seamlessly eliminates the need to drill a second hole into your expensive worktop while delivering filtered, hot, and cold water from one fixture.
About this product
A boiling tap replaces the kettle. You get water at around 98°C on demand from a spring-loaded lever, which for anyone who makes tea and coffee through the day removes a small daily friction and frees up worktop space.
An insulated 2.4-litre tank under the sink holds the hot water and reheats between draws. A carbon filter sits ahead of the tank, which does two jobs: it makes hot drinks taste better by removing chlorine, and it slows the scale build-up that shortens the life of any heated tank in a hard-water area.
The boiling lever is spring-loaded and does not stay open — you hold it to pour. That is deliberate, and it is what makes a boiling tap safe around children.
Two practical checks before you order: a 35mm sink hole, and a 13amp socket in the cupboard below. Both are required, and the socket is the one people discover they are missing after the box arrives.
Tracked delivery in 4-21 business days depending on the item. That is slower than a next-day marketplace and we would rather say so up front than surprise you at the door.

Litres and centimetres are used throughout. Cartridge life is measured in litres of filtered water, so heavily used households will change theirs sooner.
Living with a filter tap
A dedicated filtered outlet changes the day-to-day rhythm of a kitchen more than most people expect. Kettles, coffee machines, pans and water bottles all get filled from the filtered side, while washing up and rinsing continue on the mains channel, so cartridge life is spent only on water you actually drink. That single habit is what makes an under-sink tap far cheaper to run than a jug filter over a year, despite the higher purchase price.
Filtered flow is deliberately slower than a mains cold tap — typically two to four litres per minute — because the water needs contact time with the carbon media to strip chlorine and organic compounds. Hot and cold flow through a 3-way tap is unaffected, since those channels bypass the filter body entirely. If flow on the filtered side drops noticeably below its original rate, that is the cartridge telling you it is loaded rather than a fault with the tap.
Finishes matter in a British kitchen where the tap is usually the most visible piece of hardware on the worktop. Brushed steel and chrome suit most fitted units, while matt black works well against pale stone and shaker-style doors. All bodies are lead-free brass with ceramic cartridges rated for UK mains pressure, and the standard 35mm deck hole means a like-for-like swap in the vast majority of installations.

What this filter addresses
- Chlorine and chlorine taste
- Some scale-forming minerals
What it will not do
- Needs a 13amp socket under the sink. No socket, no boiling tap — there is no way around this.
- The tank stays hot, which means it draws standby power continuously. It is a small draw, but it is not free.
- The built-in carbon filter improves taste and protects the tank from scale. It is not a substitute for a full filtration system — for RO-quality drinking water you still need a system behind it.
- 2.4 litres is enough for several cups back to back, not for filling a large pasta pan in one go.
- Installation involves both plumbing and an electrical connection. This is the one product in our range where a competent DIYer might reasonably call in help.
Will this fit?
Check these before you order — they are the questions we are asked most often.
- Fits any standard 35mm UK sink or worktop cut-out
- Requires a 13amp power socket under the sink
- Requires roughly 30cm of clear cupboard height for the tank
- Pair with the Carbon Block Filter or any Clarisink RO system for filtered cold water alongside
