Electricity, water and the other bills

5 min read · Before you start: the budgeting lesson · Updated 1 November 2026

Electricity, water, internet and phone are among the few bills almost every household pays, and among the least examined. This lesson covers how they are charged, how to read them, and what the deposits, disconnection rules and reconnection costs involve.

Electricity

The Trinidad and Tobago Electricity Commission bills residential customers on consumption measured in kilowatt-hours, generally on a rate structure where the charge per unit varies by consumption band, plus fixed charges. A bill typically shows the previous and current meter readings, the units consumed, the period covered, the amount due and the due date.

An estimated reading, used when a meter has not been read, is worth noticing: it is corrected at the next actual reading, which can produce a larger-than-usual bill that is not an error but a catch-up.

Budget 2027 proposed a residential electricity surcharge above a consumption threshold, which the everyday taxes lesson tracks with its current status. Where that applies, consumption above the threshold carries an additional charge, which makes the units figure on the bill the thing to watch rather than only the amount due.

What drives a household bill

Air conditioning, water heating, refrigeration and electric cooking account for the largest share in most homes. The practical consequence is that the few largest appliances determine the bill far more than the many small ones, which is the opposite of where attention usually goes.

Water

The Water and Sewerage Authority bills residential customers, with arrangements differing between metered and unmetered properties. Where a property is unmetered, the charge is based on the property's assessed annual rateable value rather than on consumption, which means usage changes do not alter the bill.

A sudden rise on a metered account, with no change in household behaviour, commonly indicates a leak. A leak on the customer's side of the meter is generally the customer's responsibility, and a running toilet or an underground pipe can consume a great deal without being visible.

Deposits, disconnection and reconnection

New connections generally require a deposit, held against unpaid charges and refundable when the account closes in good standing. The amount differs by service and by property type.

Non-payment leads to disconnection after notice, and the full sequence costs more than the original bill: arrears, a reconnection fee, and in some cases a fresh deposit. This is why utilities appear among the priority debts in the lesson on arrears — the consequence of non-payment extends beyond the money. Where a bill cannot be met, utilities generally have arrangement processes, and those are easier to enter before disconnection than afterwards.

Internet, phone and the quiet subscriptions

Bundles combining internet, television and phone are usually cheaper than the same services bought separately, and usually include services that go unused. Promotional pricing that reverts after an introductory period is the pattern that catches households: the bill rises on a date set at signing, and the contract term determines whether leaving is possible without a penalty.

Streaming services, app subscriptions and cloud storage are individually small and collectively significant, and they renew without any action. A yearly review of what is actually charged to the card is the exercise that finds them, and it belongs with the budget review in lesson 3.

Reading a bill properly

Four things on any utility bill repay attention: the period it covers, whether the reading is actual or estimated, the consumption figure rather than only the amount, and the due date. A bill queried after the due date is a different conversation from one queried before it.

Key ideas: Electricity is billed on metered consumption in bands; an estimated reading is corrected later and can produce a catch-up bill. Unmetered water charges follow rateable value rather than usage. A sudden metered rise often indicates a leak on the customer's side. Disconnection costs arrears plus reconnection and sometimes a new deposit. Promotional pricing reverts on a date set at signing.

Where sources differ, go to the source. Rates, deposits, surcharges and reconnection fees are set by the utilities and the regulator and change. Read the official information and decide for yourself what applies to you. Useful places: T&TEC, WASA, Regulated Industries Commission.
