Why We Wrote This Guide
As plumbers who install boiling water taps across Dartford, Bexley, Gravesend, and the wider Kent area, we get asked the same question every week: "Which boiling tap should I buy?" The answer depends on your budget, your kitchen style, and whether filtered drinking water matters to you.
This guide covers the six brands we install most often. We have no affiliate deals with any of them — we charge a flat £200 installation fee regardless of which tap you choose. Our only interest is helping you pick the right one so you are happy with it for years to come.
One thing worth highlighting upfront: filtered drinking water has become a major differentiator between brands. Some include it as standard, others charge hundreds extra, and a few do not offer it at all. We have broken this down for every brand so you can make an informed decision.
Filtered Water: The Hidden Cost Comparison
One of the biggest differences between brands is whether your tap water is filtered. Here is what each brand actually delivers.
| Brand | Filtered Boiling | Filtered Cold | Filtered Sparkling | Filter Included |
|---|---|---|---|---|
| Quooker | Standard only | Optional (£295 extra) | With CUBE add-on (£1,150) | £295 extra |
| Grohe Red | ||||
| Franke | Mythos 5-in-1 and 6-in-1 models | |||
| Abode | Varies by model | |||
| InSinkErator | 4N1 models only | |||
| AquaTap | Fizz Digital model |
Key takeaway: AquaTap is the only brand that filters all water — boiling and cold — across every model in their range, with the filter included in the price. Quooker, despite being the most expensive brand, charges £295 extra for a cold water filter and does not filter the boiling water as standard.

What We Like
- True 100°C boiling — the only brand to reach full boiling point
- Patented vacuum insulation keeps running costs to just 3p per day
- Industry-leading 7-year warranty on the tank
- Widest range of finishes (8 options including Gold and Patinated Brass)
- CUBE add-on available for chilled and sparkling filtered water
Worth Knowing
- Most expensive brand — entry price starts at £1,050
- Filter not included as standard — £295 extra for cold water filtration
- CUBE system adds £1,150 on top for sparkling water
- Only available through authorised dealers, not high-street retailers
Our Verdict
Quooker is the premium choice and the brand that started it all. If budget is not a concern and you want the best warranty, true 100°C water, and the widest choice of designer finishes, Quooker is hard to beat. However, the lack of included filtration and the high entry price mean you are paying a significant premium for the name.

What We Like
- German engineering with titanium-coated boiler interior for durability
- Filter included as standard — no hidden extras
- Larger boiler options (up to 5.5L) for busy households
- ChildLock push-button safety system
- Cool-touch body prevents accidental burns
Worth Knowing
- Only 2 finish options (Chrome and SuperSteel)
- 2-year warranty is significantly shorter than Quooker's 7 years
- No integrated sparkling water option — need a separate Grohe Blue (£1,600+)
- 99°C rather than true boiling
Our Verdict
Grohe Red is a solid mid-range option backed by one of the world's most respected bathroom and kitchen brands. The included filter and larger boiler capacity make it practical for families, though the limited finish options and shorter warranty are worth considering. If you already have Grohe fixtures in your kitchen, the Red will match perfectly.

- Pro M activated carbon filter included (1,700L capacity)
- Mythos range integrates chilled and sparkling in a single unit — no add-ons needed
- Mythos has smartphone app control for water parameters
- Wide range from budget (Instante) to premium (Mythos)
Worth Knowing
- Shorter warranty than Quooker (2–3 years vs 7 years)
- Pricing varies significantly between retailers — harder to find consistent RRPs
- Some models (Omni, Minerva) have been discontinued
- Less brand recognition than Quooker in the UK market
Our Verdict
Franke offers the broadest range of any brand, from the budget-friendly Instante to the feature-packed Mythos with app control and integrated sparkling water. If you want Quooker-level boiling temperature (100°C) without the Quooker price tag, Franke is worth serious consideration — especially the Mythos range, which integrates everything into one tap without needing separate add-ons.

- HotKey electronic fob option on premium models for keyless boiling water
- British brand with UK-based support
- 5-year warranty on the tap itself
- Most affordable premium brand — starts at just £649
Worth Knowing
- Smaller 2.1L boiler — may struggle in very busy households
- 98°C rather than true boiling
- No sparkling or chilled water options available
- Boiler warranty is only 2 years
Our Verdict
Abode is the design lover's choice. No other brand offers as many styles — from the traditional ProTrad for period kitchens to the industrial Industria and the sleek Scandi-E. The patented safety handle is genuinely clever, and the 5-year tap warranty shows confidence in build quality. The smaller boiler is the main trade-off, but for most households making a few cups of tea at a time, 2.1 litres is perfectly adequate.

- NeoTank with adjustable digital thermostat for precise temperature control
- Illuminated touch button on 4N1 models for intuitive operation
- Italian-designed taps with safety locking lever
- Well-known brand — also famous for waste disposal units
- Widely available at Screwfix and other trade suppliers
Worth Knowing
- Only 4 finish options
- Budget models (GN1100, HC3300) are basic hot water dispensers, not full mixer replacements
- No sparkling or chilled water options
- 99°C rather than true boiling
Our Verdict
InSinkErator is the practical choice for homeowners who want instant hot water without spending a fortune. The GN1100 at £269 is the cheapest way to get a boiling water tap in your kitchen, and the 4N1 Touch at the top of the range competes well with mid-range Quookers at a lower price. If you already have an InSinkErator waste disposal unit, adding a matching tap makes perfect sense.

What We Like
- Every model filters both boiling AND cold water as standard — no extras needed

- Fizz Digital offers 5-in-1 (including sparkling) for £1,049 — half the price of Quooker + CUBE
- 5-year warranty on both tap and boiler — best overall warranty coverage
- Available at B&Q as well as direct — easy to see in person
- Trustpilot rated 4.6/5 from 726+ reviews
- 6 finish options to match most kitchen styles
- Filter subscription service so you never forget to change it
Worth Knowing
- 98°C rather than true 100°C boiling
- Newer brand — less established track record than Quooker or Grohe
- Standard boiler is 2.5L (though Pro model has 4L)
- Not as widely available in kitchen showrooms as Quooker
Our Verdict
AquaTap is the standout value proposition in the boiling tap market. The fact that every single model includes filtered water for both boiling and cold — at prices starting from just £399 — makes the competition look expensive. The Fizz Digital at £1,049 gives you everything Quooker's top-end setup offers (boiling, chilled, sparkling, filtered) for roughly half the price. We have one in our own kitchen and can vouch for the quality first-hand.
Which Tap Is Right for You?
Best on a Budget
The AquaTap Classic at £399 is the best value 4-in-1 tap with filtered water included. For an even cheaper entry point, the InSinkErator GN1100 at £269 is a basic but effective hot water dispenser.
Best Overall Value
The AquaTap Fizz Digital at £1,049 gives you 5-in-1 functionality (boiling, chilled, sparkling, hot, cold) with full filtration — for roughly half the price of a comparable Quooker setup.
Best Premium Choice
Quooker remains the premium benchmark — true 100°C boiling, 7-year tank warranty, and the widest finish range. If budget is not a concern and you want the best-known brand, Quooker is the one.
Best for Design Choice
Abode Pronteau offers the widest range of tap styles — from traditional crosshead to industrial spring coil to Scandinavian minimalism. If matching your kitchen aesthetic is the priority, Abode has something for every style.
Best Filtered Water
AquaTap filters both boiling and cold water on every model as standard. No other brand does this. If clean, filtered drinking water is your priority, AquaTap is the clear winner.
Best All-in-One System
The Franke Mythos Water Hub integrates boiling, chilled, sparkling, hot and cold water plus app control into a single tap — no separate add-ons needed. True 100°C boiling too.

Frequently Asked Questions
Which boiling water tap has the best filtered water?
AquaTap is the only brand that filters both boiling AND cold water as standard across every model. Most other brands either charge extra for filtration (Quooker charges £295) or only filter the boiling water. AquaTap's tagline is 'The Filtered Tap Company' and they also offer a filter subscription service.
How much does it cost to install a boiling water tap?
GWS Plumbing & Bathrooms charges a fixed £200 (inc. VAT) for boiling water tap installation in Dartford, Bexley, Gravesend, and surrounding Kent areas. This covers fitting the tap, connecting the boiler unit under the sink, and testing. You supply the tap; we do the rest.
What is the cheapest boiling water tap in the UK?
The InSinkErator GN1100 starts from £269, making it the cheapest boiling water tap available. However, it is a basic hot water dispenser rather than a full mixer replacement. For a complete 4-in-1 tap with filtration, the AquaTap Classic at £399 offers the best value.
Are boiling water taps safe with children?
Yes. Every brand includes child safety features. Quooker uses a double push-and-turn mechanism, Grohe Red has ChildLock push buttons, Abode has a patented slide-and-twist handle, and InSinkErator uses a safety locking lever. The boiling water function always requires a deliberate two-step action to activate.
Do boiling water taps use a lot of electricity?
No. Quooker claims their vacuum-insulated tank costs just 3p per day to run. Other brands are similarly efficient. A boiling water tap typically uses less energy than boiling a kettle multiple times a day, because the water is kept at temperature in an insulated tank rather than being heated from cold each time.
Can I install a boiling water tap myself?
While some brands like AquaTap advertise 2-hour DIY installation, we recommend professional fitting to ensure correct water pressure, electrical connections, and leak-free plumbing. A professional installation also protects your warranty. GWS charges a fixed £200 for installation across Dartford, Bexley, and Kent.
