Water and Electricity Bills in Malta: ARMS Accounts Explained

ARMS issues the combined electricity and water bills used by households in Malta. The total is not based only on how much electricity or water you used: the billing period, tariff classification, number of registered residents, service charges, meter readings, previous balances and adjustments can all affect it.

The quickest way to understand a bill is to check its account details and readings before looking at the final amount. If you rent, do this before moving in as well as when the first bill arrives.

What to check on an ARMS bill

Work through these items in order:

1. Account holder and service address: confirm that the bill belongs to the correct property and consumer.
2. Billing period: note the start and end dates. ARMS says bills should normally be issued every two months, but compare the exact number of covered days rather than assuming every bill represents the same period.
3. Consumer scheme or tariff: the bill identifies the account type. ARMS publishes domestic, residential and non-residential tariff categories; they are not interchangeable.
4. Number of registered persons: this appears near the top-right of the bill and affects the household's tariff treatment and possible eco-reduction.
5. Electricity and water readings: check the previous and current readings and whether they are actual, supplied by the consumer or estimated.
6. Consumption: subtract the previous reading from the current one and compare the result with the bill. For a water meter, ARMS instructs consumers to read the black digits and ignore the red digits.
7. Charges and credits: separate electricity consumption, water consumption, service charges, eco-reduction, adjustments, payments and any older balance.

A larger total does not necessarily mean your daily usage increased. A longer billing period, an earlier unpaid balance or the reconciliation of an estimate can make one bill look unusually high.

Why the number of registered residents matters

ARMS calculates certain household entitlements using the number of people registered on the billing account. The official tariff page says that the correct residents must be registered to benefit from the applicable residential treatment and eco-reduction.

Check the number shown on every first bill after moving home. Registration is not automatic, and one person cannot receive the number-of-persons benefit on more than one account at the same time.

If the number is wrong, use Form H — Change in the declaration of number of persons from the ARMS application forms. ARMS states that, unless you previously notified it of the change, the benefit normally applies to bills issued after the update rather than correcting all earlier bills retrospectively. Keep proof of submission.

ARMS also publishes restrictions on how often a person's registration can be moved and when a change made late in the year takes effect. If someone was recently registered at another address, confirm the current rule with ARMS before relying on an immediate transfer.

Domestic, residential and non-residential accounts

Do not treat the word domestic as proof that the correct residents or subsidy are already attached to the account. ARMS explains that a domestic account can have no people registered for the number-of-persons benefit, while its tariff page separately distinguishes domestic, residential and non-residential rates.

The practical checks are therefore:

• What consumer scheme is printed on the bill?
• How many people are shown as registered?
• Does that match who actually lives at the property?
• Has each resident been removed from any previous account?

If the classification itself appears wrong, the forms list includes Form R — Request to Change Billing Tariff. Ask ARMS which form applies to your circumstances rather than selecting a tariff solely from a landlord's description.

What tenants should arrange

Before signing a lease, ask to see a recent complete bill with personal information that is not relevant to you covered. Check the property address, tariff, registered-person count, billing period, readings and whether an unpaid balance exists.

At handover:

1. Photograph both meter serial numbers and readings clearly.
2. Record the date and time and send the readings to the landlord or agent in writing.
3. State in the lease who receives the bill, who pays ARMS and who submits resident or account changes.
4. Keep copies of every form, email, receipt and bill paid during the tenancy.

There are three different actions that are easily confused:

• Form H changes the number of people registered on the existing account.
• Form F registers a change in the consumer, placing the account in another person's name. ARMS says this depends on agreement with the owner. Its current FAQ also says a tenant taking the account into their own name pays a €466 deposit, which is offset against the final bill and any remaining credit returned.
• Form F2 provides temporary recognition of a tenant with a signed lease when the owner refuses to cooperate with the normal resident-registration process.

ARMS says changing the account holder is generally not recommended for a tenancy shorter than two months. If you do take the account into your name, arrange to transfer it back before leaving; otherwise later bills can continue to be issued to you.

How to estimate your own bill

Generic monthly averages are unreliable because household size, billing days, tariff registration, air-conditioning, electric water heating, appliance efficiency, solar panels and leaks vary considerably.

Use the official ARMS bill calculator with information from the property instead. It asks for:

• the exact start and end dates;
• the consumer scheme printed on the bill;
• the number of registered people;
• the electricity meter phase and start/end readings;
• photovoltaic details, if applicable; and
• the water meter's start/end readings.

The calculator then separates electricity and water consumption, service charges, eco-reduction, photovoltaic refunds and VAT where applicable. ARMS describes it as an illustrative self-help tool, not a replacement for the issued bill; if the two disagree, investigate the inputs and raise the difference with ARMS.

For a rental budget, request several recent bills covering both hot and cooler months. Divide each total by its exact number of covered days and multiply by 30 to get a comparable monthly equivalent. Also check whether those bills used actual readings and the same number of registered residents you expect to have.

What to do when a bill looks too high

First establish whether the issue is consumption, billing data or an older charge:

1. Photograph today's electricity and water readings.
2. Compare the meter serial numbers and readings with the bill.
3. Check whether the bill says the readings were estimated.
4. Compare consumption per day with the previous actual-reading period.
5. Confirm the tariff and registered-person count.
6. Look for an earlier balance, adjustment, deposit or longer billing period.
7. If consumption really increased, check likely causes such as air-conditioning, electric water heating, dehumidifiers, pool equipment or a water leak.

An estimated bill may be reconciled when an actual reading becomes available. ARMS says consumers normally need to submit readings only when a meter-reader notice specifically asks for them within five days; registered users can also access the readings area online.

If the physical meter still appears wrong, the application list includes Form He for testing or changing an electricity meter and Form B for testing or changing a water meter. ARMS states that an electricity-meter test carries a charge which is refunded if the meter proves faulty.

How to query or contest a bill

Contact ARMS with a precise evidence pack rather than only saying the bill is too high. Include:

• the account and invoice numbers;
• the disputed billing period and amount;
• photographs of the meters and serial numbers;
• your calculation of the reading difference;
• the lease and handover readings if you rent;
• receipts for Form H, Form F or Form F2; and
• the exact correction you are requesting.

Use the official ARMS contact form and contact details, and retain the reference number or written reply. ARMS says valid contested amounts do not attract interest, but do not assume that merely sending a complaint pauses the entire bill. Ask ARMS what should be paid while the query is being investigated.

ARMS warns that overdue balances can attract interest and that continued non-payment can eventually lead to service suspension. Use the due date printed on the invoice and raise a dispute promptly.

Paying an ARMS bill

The ARMS Quick Pay service allows someone to pay all or part of a bill, including on behalf of another person, without logging in. You need the account number, invoice number, amount and payment-card details. Logging into My Utilities provides the bill details and payment history that Quick Pay alone does not show.

ARMS also lists direct debit, supported internet-banking services, ATMs, MaltaPost branches, post and customer-care offices as payment routes. Whatever method you use, keep the receipt and check that the payment appears in the account history or next bill.
