Electricity, Propane Gas, Water and Petrol & Diesel

Last updated: 29h January 2015

In this section we explain how you go about connecting up your utilities (electricity and/or propane gas, and water) in Grand Cayman. We discuss what you need, how much it will cost and where you can find them. We then explain how the gas stations work and what the current price is for petrol. 

The sole provider of electricity to Grand Cayman is Caribbean Utilities Company, Ltd. (CUC). To obtain electricity service, property owners are required to pay a deposit and show proof of ownership and a photo ID. Tenants are required to pay a deposit, provide a rental agreement or lease and take their passport or driver’s licence along for photo ID. The required security deposit for electricity is calculated based on the average historical useage of 45 days of consumption on existing accounts. Deposits for new residential homes/condos are calculated based on a combination of square footage and number of bedrooms.

Cayman runs on a 120 volt electricity system with three-pin plugs. However, the outlets are designed to accommodate a two-pin American plug (see picture on opposite page). This means appliances from the United Kingdom or Europe will not work in Cayman, without an adaptor, but American appliances will. Monthly electric bills will vary depending on the size of your house/condo/apartment, your lifestyle, how often you run your air conditioning, the efficiency of your air conditioning unit, the age of the property and how well the property is insulated, among other factors. It is important to note that the Seasonal Energy Efficiency Rating (SEER) and regular maintenance of your air conditioning unit can make a big difference in kilowatt-hour (kWh) consumption and your monthly electric bill. The lower your SEER, the more power you will consume. A SEER of 12 for example, will consume more than a SEER of 14 or higher. Getting your air conditioning unit serviced regularly will ultimately save you money.

The base cost of electricity as of December 2014 was CI$0.1031 per kWh for residential customers with a monthly facility charge fee of CI$5.17 and a regulatory and licencing fee of CI$0.0074 per kWh which applies only to usage over 1,000 kWh per month. However, if you factor in the fuel and fuel duty surcharges (which are added as separate line items and vary from month to month), the cost per kWh is approximately CI$0.317 (as of December 2014). The Government duty on fuel is CI$0.75 per imperial gallon. The fuel cost fluctuates with the global price of oil and the cost of fuel is passed down to the consumer after a two-month lag.

To put it all into perspective, usage of 1,000 kWh per month would cost approximately CI$317.00 and usage of 1,500 kWh would cost CI$479.20 (based on the December 2014 rate). The cost of electricity is the same island-wide and does not fluctuate depending on the time of day. You can download customer service forms from CUC’s website.

Gas - Household
Propane is a non-toxic gas used as a clean burning alternative energy source for a wide range of indoor and outdoor appliances. The cost of a 100lb cylinder is CI$98 (including free delivery) and can be ordered online from, by phone from Home Gas Ltd. or by stopping in to their offices. The 20lb cylinders used for barbecuing can be found at almost all of the gas stations in Cayman, where you can buy a new filled cylinder or swap an empty used cylinder for a full one. The cost is about CI$40 to exchange a cylinder. For bulk delivery of propane the cost is CI$4.80 per gallon. 

Many houses in Cayman have an underground refillable propane tank in their garden or one standing alongside an exterior wall and the gas is then piped into the house. The size options for the tank vary depending on the amount and type of appliances that you will be running on propane. Home Gas’ technicians can advise on which appliances you could use and what energy savings you might expect. They are also trained to install all their equipment properly. There are many gas appliances available that will help you lower your energy costs. It is commonly acknowledged that running appliances using propane is a much more energy efficient approach to powering a home. Another benefit is that many of your propane appliances can still be used even in the event of a power outage. If you would like a free consultation to determine the energy savings your home or company can achieve by switching to propane, call Home Gas.

Their services are available in Grand Cayman, Cayman Brac and Little Cayman. Bills can be paid online if you bank at Butterfield, CNB, RBC or CIBC FirstCaribbean.

Petrol & Diesel
In Grand Cayman, there are numerous Esso and Rubis petrol stations, most of them with convenience shops selling toiletries, groceries, water, gas cylinders and snacks (incidentally, they are almost the only places open on a Sunday where you can buy essential supplies). The average cost of full service premium petrol at the pumps is now around CI$5.05 per gallon, although prices vary from one station to another. Self-serve petrol can be between 5¢ and 10¢ cheaper per gallon, while diesel is around CI$5.17 per gallon (January 2015). The current cost of premium petrol in Florida was in the region of US$2.15 per gallon or CI$1.76 and in the UK it costs £1.12 per litre (US$4.23 per gallon). The cost of gas in Cayman Brac is CI$5.75 per gallon even though a ship does directly to Cayman Brac to fill up their fuel tanks and the Cayman Islands Govt's duty on gas has been reduced. [Editor: there have been a LOT of complaints on local talk shows about this in January 2015]. The cost of gas in Little Cayman is CI$6.49 per gallon (as of January 5th 2015).

Please note that the petrol pump nozzles on both diesel and petrol are the same size in Cayman, unlike in Europe and the US, where they are different sizes. Therefore, it is quite possible to mistakenly put diesel in a petrol-run car. You can view the cost of petrol at each station on (look under petroleum inspectorate). The (import) duty component of gasoline is 75 cents per imperial gallon and 85 cents for diesel. Though the Government reduced the duty on diesel by 25 cents per gallon in the 2014 budget, it is only for diesel being imported by CUC for electricity generation.

The quality of gasoline sold in Cayman is equivalent to a mid-grade unleaded (octane level 89) and a super premium unleaded (octane level 93) often sold in the US. Some high performance cars, particularly those with sophisticated emissions control equipment, namely a catalytic converter, will experience problems (it will clog up) if they are not run on the highest octane fuel available. By August 2013, there had been enough complaints about the quality of fuel being sold at local gas stations, that the Petroleum Inspectorate Department conducted a thorough review of both the diesel and the gas being sold at each gas station. The result was that they found wide variances in the quality of fuel. The upshot of this is that regular testing by the Inspectorate has been initiated, tanks have been cleaned and the quality of fuel has improved dramatically.

For a long time diesel had been a problem. It started with the fact that gas stations sold the same diesel that was imported primarily for electricity generation and thought little of the fact that the sulphur content was between 500-5,000ppm. Problems then arose with the deposits from the sulphur building up in the car’s engine and exhaust filters, so much so that some cars were damaged irreparably. Car manufacturers design their engines to run on fuels found in the country where the cars will be used, and cars in Europe and Japan, for example, have low emission standards and require that all diesel sold has a sulphur content of 10ppm. The US also has Ultra Low Sulphur Diesel (ULSD) of about 15ppm and most USA diesel vehicles require ULSD (and a minimum cetane level of 40) to function properly. A major change came in mid-2013 when Esso advertised that they were now importing ULSD and Rubis followed suit in May 2014. However, for years prior to this, Scotts Landing, at the Barcadere Marina (at the end of North Sound Road past CUC) knew about this problem and started selling a boutique fuel called ValvTect, which they still sell. Their strategy is to constantly test the fuel available at both Esso and Rubis and then only buy the highest octane gasoline and ultra low sulphur diesel available. They then treat it with ValvTect, an additive and cetane booster, which improves the performance and lubricity of the fuel.

Cayman Water (Tel: (345) 945 4277) and the Water Authority (Tel: (345) 949 2837) supply Grand Cayman with quality water. In the case of both companies, water is extracted from 250ft-deep wells located throughout the Island. The water that is extracted is essentially seawater and so has to be treated via the reverse osmosis process to produce drinking water. This process, together with the addition of three fluoride-free chemicals, makes the water safe to drink straight from the tap. However, it does taste a bit chlorinated, even filtered through a fridge filter, so you may want to use a filtration system or buy bottled water.

If you are renting an apartment, the water bill must be in the landlord’s name, however a duplicate bill will be sent to you directly for payment. Landlords may also ask for a water deposit. Of the two water companies, Cayman Water serves the Seven Mile Beach and West Bay areas, while the Water Authority serves the rest of Grand Cayman. They both require you to fill out an application, present your Land Registry form (which proves you own the house) and pay a CI$80 non-refundable connection fee. Also, make sure the previous owners have paid the last water bill, as having an outstanding balance on your account will complicate things. Water is not cheap, so also make sure you don’t run up a huge bill by having a leaking tap or running toilet. At Cayman Water, the first 3,000 US gallons (or 11m³) will be charged at CI$19.37/m³. Anything above that will cost CI$23.24/m³. An energy adjustment factor surcharge is applied each month that varies according to the cost of electricity. Monthly meter charges also vary depending on the size of the meter, from CI$3.50 to CI$40 for meter sizes ranging from 5/8” to 6”. Cayman Water’s website provides additional information to customers, such as current water quality data and answers to other frequently asked questions (  

At the Water Authority, the first 12 cubic meters (or 3,200 US gallons) will be charged at CI$4.38/m³. Anything above that will cost CI$5.57/m³. In addition, there is also an energy charge (which varies monthly and covers the fluctuations in the cost of electricity to produce the desalinated water) and a CI$5 meter rental fee per month. An average water bill for two people in a two-bedroom house using 9m³ per month, is approximately CI$90. The Water Authority Cayman’s website ( provides information on outages, tips on saving water, water and sewage application forms, meter reading request forms and online fault reporting. They also offer water-saving shower heads for free. For after hours emergencies call (345) 946 4357.

If your home is on a cistern or well water, you will probably want to drink bottled water or you will need to boil the water before drinking it. Alternatively you could get bottled water delivered to your home by Flowers Bottled Water.

Flowers Bottled Water
Seymour Road, Industrial Park
Tel: (345) 949 8688
Sells purified water (that contains no chlorine) in five-gallon BPA free bottles for CI$6 each, with free delivery to your home or office, or convenient pick up at petrol stations Islandwide. They also sell and rent hot/cold and cold water coolers along with other accessories.

Alternatively, many supermarkets sell spring water by the case or you can import three or four stage under-the-sink well water or city water filters. The city water filter removes all the chlorine that is put in desalinated water. See They import directly to Cayman and then it is a simple job for a plumber to fit it under the sink.
