There are two different electrical systems on the islands. One is the 110 volt system and the other is the 220 volt system. There are some buildings which will allow you to use either system, though if you are bringing appliances from your home country you will need to check in advance to establish the system being used in your new home and to determine whether or not you need to purchase adaptors.

Having electricity connected to your new home can generally be arranged by the estate agent dealing with your property purchase or rental, although you are able to arrange this yourself if you prefer. As a foreign national, you need to be prepared to pay a larger deposit to have utilities connected and provide proof of identification and residency status. There may also be a minimum contract that you need to sign up for, either for six or twelve months, though this will depend on your circumstances and residency status.

All tap water is treated and is suitable for drinking, although it may be that some people will take a while to get used to it, in which case the use of a water filter or bottled water is advised. Most inhabitants prefer to use bottled water for drinking. Again, having domestic water supplies connected to your home can be done by the estate agent, and you may be asked to pay a deposit.

If you choose to arrange utility connection yourself you should contact the utility companies directly and present them with the relevant documentation and deposit payment. It is better to do this in person and go to your local office. Your estate agent will be able to point you in the right direction.

There are no piped domestic gas supplies but you can purchase bottled gas for use with any gas appliances that you may have. Most homes will rely solely on electricity for all their power needs. It should be noted that in the hot climate the use of air conditioning units can make electricity bills very expensive.

The Antigua Public Utilities Authority is responsible for overseeing utility supplies and regulating the service. They oversee water, electricity and telephone services. There have been recent measures put in place to ration water in Antigua and Barbuda due to a lack of rainfall to conserve supplies. In times of shortage homes will only receive domestic water supplies at certain times of day.
