The cost of running a water cooler in the UAE depends partly on which emirate your office is in, because each utility sets its own tariff. It depends even more on where your whole premises sits on that utility's consumption slabs, because the dispenser's kilowatt-hours are charged at the building's top rate. For a busy chilled unit in a Dubai or Northern Emirates office, that works out at roughly AED 60 to AED 100 a year. Filters, servicing and bottles usually cost far more.
This guide is for office, clinic and hospitality managers across the Emirates who want to budget a dispenser properly or compare mains-fed with bottled supply.
TL;DR
- DEWA and Etihad Water and Electricity both charge commercial users 23 to 38 fils per kWh in four slabs, plus a fuel surcharge of 6 fils (DEWA) or 5 fils (Etihad WE).[1][2]
- Most offices use enough power for the dispenser to be billed at the top slab: about 43 to 44 fils per kWh before 5% VAT.[3]
- On BRITA's published figures, a busy chilled dispenser costs about AED 60 to AED 100 a year to power. A boiling-and-chilled tap costs about AED 180 to AED 300.
- In Abu Dhabi and Sharjah, use the rate on your own bill. We could not verify a current published commercial rate for either.
- Heat, filters, service visits and bottles decide the real annual cost.

How UAE utilities charge a business for power
There is no single national tariff. Each emirate's utility bills its own customers:
| Emirate | Utility | Commercial energy rate | Fuel surcharge |
|---|---|---|---|
| Dubai | Dubai Electricity and Water Authority (DEWA) | 23, 28, 32 or 38 fils per kWh by monthly slab | 6 fils per kWh |
| Ajman, Umm Al Quwain, Fujairah, Ras Al Khaimah | Etihad Water and Electricity | 23, 28, 32 or 38 fils per kWh by monthly slab | 5 fils per kWh |
| Abu Dhabi | TAQA Distribution (formerly ADDC and AADC), regulated by the Department of Energy | Check your bill | Check your bill |
| Sharjah | Sharjah Electricity, Water and Gas Authority (SEWA) | Check your bill | Check your bill |
The DEWA and Etihad WE slabs are the same: 0 to 2,000 kWh a month at 23 fils, 2,001 to 4,000 at 28, 4,001 to 6,000 at 32, and anything above 6,000 at 38.[1][2] DEWA's fuel surcharge can change, so confirm the current figure on its tariff page. VAT at 5% applies to utility bills.[3] In Abu Dhabi, the distribution companies now trade as TAQA Distribution.[4]
Why your dispenser pays the top slab
Slabs are counted across all the power your premises uses in the month, not per appliance. An office with air-conditioning, lighting and IT will often pass 6,000 kWh a month, especially in summer. Any extra unit the dispenser adds is then billed at the highest slab. Only a very small unit, such as a single shop or a small clinic, may sit in the lower slabs all year.
So the useful question is not "what is the tariff?" but "what is the last slab on our bill?". Use that rate, add the fuel surcharge, then add VAT.
Annual power cost by emirate
We used BRITA's published energy values, each measured over 24 hours for a stated daily volume.[5] We assumed 250 days of normal use and 115 quieter days with the unit left on, which suits a Monday to Friday office in the Emirates.
- Clinic reception, about 10 people, chilled only: BRITA Top Compact at 10 litres a day, about 68.6 kWh a year.
- Office floor, about 50 people, chilled only: BRITA Top Pro at 60 litres a day, about 219.7 kWh a year.
- Office floor, about 50 people, boiling and chilled: BRITA Extra C-Tap at 10 litres hot and 60 litres chilled, about 652 kWh a year.
| Workplace | DEWA, lowest slab (29 fils) | DEWA, top slab (44 fils) | Etihad WE, lowest slab (28 fils) | Etihad WE, top slab (43 fils) |
|---|---|---|---|---|
| Clinic reception | AED 20 | AED 30 | AED 19 | AED 29 |
| Office floor, chilled | AED 64 | AED 97 | AED 62 | AED 94 |
| Office floor, boiling and chilled | AED 189 | AED 287 | AED 183 | AED 280 |
Figures include the fuel surcharge and exclude 5% VAT. At the DEWA top slab with VAT, the chilled office floor comes to about AED 101 a year and the boiling-and-chilled floor to about AED 301.
The BRITA Top Pro is the unit in the chilled office floor example.
Boiling water for the pantry
A tap that holds water near boiling uses more power than a chiller, which is why the third row is higher. But offices that install one usually retire kettles or an urn. BRITA's comparison puts a kettle serving a 50-person office at about 1.8 kWh a day with reboiling, while its C-Tap delivering boiling and chilled water uses 2.24 kWh a day with a nine-hour night mode.[5] Once the kettle and a separate chiller are gone, the difference on the bill is small.
The BRITA Extra C-Tap supplies boiling, chilled and sparkling water from one outlet. Our instant boiling water tap versus kettle guide for the UAE compares the two in more depth.
What the climate adds
BRITA's energy values come from controlled tests. UAE summers push real use higher in three ways:
- Warm incoming water. Water stored in tanks on roofs or in basements warms up in summer. BRITA rates its CLARITY Protect 100 dispenser filter for water inlet temperatures of 4°C to 30°C.[5] Ask your installer to measure the temperature at the connection point.
- Hot rooms. The same filter is rated for surroundings up to 40°C.[5] A pantry where the air-conditioning switches off at night, or a unit placed next to a dishwasher or in sun through glass, can exceed that.
- Longer compressor running. More heat in means more running time, which raises energy use and wears parts sooner.
For a site that is hard to keep cool, add a margin to the energy figures above.
Filters, servicing and bottles
These lines usually dwarf the electricity.
Filters. BRITA's CLARITY Protect 100 has a nominal capacity of 11,500 litres.[5] The chilled office floor draws around 15,000 litres a year, so it needs more than one cartridge a year on volume alone, or sooner if the time limit is reached first. Our water quality and TDS guide for the UAE explains what the filter is dealing with.
Service visits. A visit should include the filter change, sanitisation of the waterways and a function check. Agree the number of visits and the fault response time in writing. Sovereign Water's maintenance service works to a fixed schedule.
Bottles. A bottled cooler uses about the same electricity as a mains-fed one, but the water is bought by the bottle. The 15,000 litres a year above equals about 794 bottles of 18.9 litres, or roughly 16 a week. Multiply by your supplier's price, then add deposits, delivery and cooler rental. For the full comparison, see our mains-fed versus bottled guide for UAE businesses and our water cooler rental cost guide for the UAE.
Frequently asked questions
How much does a water cooler cost to run in Dubai?
On BRITA's figures, a busy chilled unit uses about 220 kWh a year. At DEWA's commercial rates with the fuel surcharge, that is about AED 64 to AED 97 before VAT.
Which DEWA slab applies to my dispenser?
The slab depends on your premises' total monthly use. Most offices pass 6,000 kWh, so the dispenser's units are billed at 38 fils plus the fuel surcharge.
What about Abu Dhabi and Sharjah?
Use the rate on your TAQA Distribution or SEWA bill. The same energy figures apply, so multiply the kWh by your rate.
Is VAT charged on electricity in the UAE?
Yes, at 5%.
Is bottled water cheaper to run than a mains-fed cooler?
Rarely for a permanent office. Power use is similar, but bottled supply adds a cost for every litre.
