Power and water in Malta: ARMS bills and the tariff trap

In Malta there's no shopping around for a cheaper electricity plan. There's one bill, from one company, and the trick is making sure it charges you the right tariff.

The short version

• Power and water bills come from ARMS Ltd, a single billing company for both. Enemalta runs the electricity network and the Water Services Corporation runs water.
• Homes are billed on either the residential tariff (your main home) or the domestic tariff (holiday homes and empty places). Residential is cheaper [1].
• You only get residential rates and the eco-reduction if the people living there are registered on the account. Tenants do this with a form and their residence card [1][2].
• Electricity is charged in bands. The first 2,000 kWh cost €0.1047 a unit in 2026, rising to €0.6076 above 20,000 kWh [3].
• Rubbish goes out in coloured bags on set days. A bag on the wrong day can mean a €25 fine [4].

Who does what

Australians are used to picking an energy retailer, connecting in their own name and switching when a better deal shows up. Malta works differently.

There's no comparison site and no switching. The only lever you control is being on the right tariff with the right number of residents, and then how much you use.

The residential tariff trap

This is the part that catches newcomers. ARMS charges two household tariffs:

• Residential: for a home where people live as their main residence. Cheaper unit rates, plus the eco-reduction, a discount based on the number of people registered on the account [1].
• Domestic: for second homes, holiday lets and premises with nobody registered. No eco-reduction and higher rates [1][6].

Many rental flats sit on the domestic tariff because the landlord, or the last tenant, never registered anyone. If your bill says "Domestic" rather than "Residential", there's a good chance you're paying too much [6].

The water bill works the same way: the number of people registered sets your subsidised water allowance [2].

How to get on the residential rate

The fix is the government form to change the declared number of persons living at a property, often called Form H [2][6]. Here's the process.

1. Get your residence card first. The form needs scans of the front and back of a Maltese ID card or residence permit for every resident over 16 [2]. Our guide to Identità and the residence card explains how long that takes.
2. Check whose name is on the account. Ask your landlord or agent before you sign. Some agents hand over the form with the lease [6].
3. Submit the form online. It's on servizz.gov.mt. Each person can be registered at only one premises and on only one account [2].
4. Wait about two weeks. Allow around a week for submission and another for vetting and processing [2]. Bills issued after the change reflect the new number [2].
5. Check the next bill. Look for "Residential" and the right number of persons. If it's wrong, call ARMS on 8007 2222 [2].
6. Deregister when you leave. Your registration doesn't move with you. Take a final meter reading, settle the bill and register at the new address [6].

The flat-fee landlord

Some landlords keep the ARMS account in their own name and charge tenants a fixed monthly amount for utilities [6]. That isn't automatically dodgy, but it means you can't see the real bill or spot a tariff error. If you're offered this, ask to see recent ARMS bills and confirm the account is on the residential tariff with you registered. Write in the lease how utilities will be charged and how meter readings are shared. Unpaid ARMS bills are a common source of end-of-lease disputes, so get it on paper. Our renting in Valletta guide covers leases and deposits.

What power and water cost

Enemalta publishes the residential electricity bands, and they include 5% VAT [3].

On top of usage there's a fixed service charge, €65 for a standard single-phase supply [3]. The eco-reduction trims the bill further for registered households that keep usage low [1].

Those first two bands are cheap by Australian standards, and Eurostat data for the first half of 2025 put Malta's household price at about €0.12 per kWh, the second lowest in the EU [5]. The sting is in the upper bands. A big household running air-con around the clock can push into the €0.34 band, where a unit costs more than three times the starting rate.

Water is billed by ARMS too, and the subsidy you get depends on the number of registered residents [2]. The regulator, REWS, publishes current water and electricity tariffs, and ARMS has a bill calculator on its website [1]. Tap water is safe but often desalinated and tastes of it, so most households buy bottled water or use a filter for drinking.

Summer air-con: keeping the bill down

Malta's summer runs from June to September, and July is the hottest month [7]. Air-con is how most people survive it, and it's where bills blow out.

• Use split systems smartly. Cool the room you're in, not the whole flat. Set 25–26°C rather than 20°C.
• Close the shutters. Traditional timber shutters and closed balconies (gallariji) keep the afternoon sun out.
• Clean the filters. Dusty filters make units work harder. Ask your landlord when they were last serviced.
• Run heavy appliances at night. It keeps the flat cooler, even if it doesn't change the tariff.
• Watch the bill against the bands. If your summer bill jumps, check you're on residential rates before blaming the air-con.

Rubbish: a bag for every day

Malta sorts household waste into coloured bags, collected door to door on set days. The national schedule looks like this [4][8]:

Mixed waste must go in transparent black bags so inspectors can see what's inside [9]. Inspectors check that waste is sorted, in the right bag and out on the right day. Fines are €25 for households and €50 for repeat offenders [4].

Collection times vary by locality, and Valletta's narrow streets have their own rhythm. Check with the Valletta Local Council for what time to put bags out, and keep them inside until then. A bag left out overnight in August is a cat magnet.

Bulky items like old mattresses aren't left on the kerb. Councils run bulky-waste pickups by appointment, and there are civic amenity sites for larger loads.

Your first-month utilities checklist

1. Ask before signing whether the ARMS account is in the landlord's name and on the residential tariff.
2. Photograph the electricity and water meters on move-in day.
3. Register everyone living there as soon as your residence cards arrive [2].
4. Find out your street's bag times from the council.
5. Buy white, grey or green, and transparent black bags at any grocer.
6. Check the first full bill for the word "Residential" and the right number of people.
