Fuel Mix Gas supplier sourcing locations

How Is My Gas Consumption Converted to kWh?

Gas meters measure in cubic metres (m³) rather than kilowatt-hours. Due to variable energy content based on weather and supply conditions, Gas Networks Ireland applies conversion using three factors:

  • Volume (m³): Consumption amount from meter reading
  • Calorific Value: Energy content representation of regional gas supply
  • Conversion/Correction Factor: Adjustment based on atmospheric temperature and pressure

The result yields the final kWh figure multiplied by unit price rate.

How Is Gas Bill Calculated?

Calculation Steps:

  1. Obtain Your Gas Usage - Average: 11,000 kWh/year, multiplied by unit rate
  2. Include the Carbon Tax - Multiply 1.104 cents/kWh by gas usage
  3. Add Your Standing Charge - Annual standing charge from supplier
  4. Add it All Together - Sum all components

Example Calculation (Urban Household):

  • Consumption: 11,000 kWh/year
  • Unit rate: €0.1164/kWh
  • Annual consumption cost: 11,000 × €0.1164 = €1,280
  • Annual standing charge: €155.96
  • Carbon Tax: included
  • Total annual bill: €1,435
  • Bi-monthly bill: €239.17 (€1,280.27 ÷ 6)

What About Water and Waste Collection Bills?

Water Charges in Ireland

Domestic water usage in Ireland is primarily funded through general taxation and not directly billed like gas or electricity. Charges apply for private water supplies (wells) or commercial customers. Contact your local authority for concerns about supply or septic tanks.

Waste Collection

Managed by private companies licensed by local authorities. Bills vary significantly by provider and plan structure:

  • Annual or Monthly Fee: Flat rate regardless of disposal volume
  • Pay-By-Weight: Charge based on bin weight; encourages recycling/composting
  • Lift Charge: Per-collection fee plus annual service fee

Why Is My Utility Bill Unusually High?

Consider these issues before contacting your supplier:

  1. Season - Winter heating costs significantly higher; summer air-conditioning/fans increase usage
  2. Household Improvements - Renovations/extensions and contractor electricity increase bills
  3. Rate Increase - Variable tariff unit rates may have increased; government levies like carbon tax changes
  4. Discount Period Ended - Previous switch discounts may have expired; renegotiate or switch providers
  5. Additional People - Visitors or increased home occupancy increase showers, heating, electricity usage
  6. Moving Home - New home may lack energy efficiency or be larger; examine heating/hot water elements
  7. Estimated Bills - If large estimated bill, usage may have been overestimated
Selectra's Electricity Meter Tip: Avoid overpaying on estimated bills by installing a smart meter for accurate meter readings. If you are still waiting for a smart meter to be installed, contact ESB services to arrange for one to be installed.

What If I Can't Pay My Energy Bills?

Talk To Your Supplier

Contact your energy supplier's customer service centre and explain your financial difficulty. The CRU (Commission for Regulation of Utilities) requires suppliers to:

  1. Assist customers in genuine financial difficulty
  2. Maintain trained staff for bill payment problem discussions
  3. Offer alternative payment methods or cost spreading options
  4. Adhere to Energy Engage Code (promise no disconnection; work toward practical solutions)

Social Welfare Supports

The Government through the Department of Social Protection offers supports for low-income households:

  • Additional Needs Payment - Means-tested financial support for essential services including home energy bills; amount depends on weekly income

What Are My Rights If I Have a Dispute About My Utility Bill?

The Three-Step Dispute Process

  1. Contact Your Supplier: Call, email, or write customer service department with account number, clear issue description, and expected resolution. Obtain reference number.
  2. Supplier Investigation: Supplier investigates and provides full resolution or final response (typically 10 working days).

Switching Providers

The CRU recommends switching electricity and gas providers around annually for cheapest rates.

Benefits of Switching Energy Supplier:

Top Energy-Saving Tips for Your Home

  1. Check for Drafts: Use foam strips or door snakes to seal windows, doors, letterboxes; cheapest energy efficiency improvement
  2. Optimise Your Thermostat: Reduce thermostat 1°C to lower heating energy use by up to 10%; use timer for occupied-hours heating only
  3. Manage Hot Water: Heat only needed water amount; immersion heater typically 1 hour for shower or bath
  4. Use Appliances Efficiently: Run washing machines/dishwashers with full loads; use eco/lower-temperature settings
  5. Eliminate "Vampire Power": Unplug chargers and devices (TVs, game consoles) left on standby; reduce idle electricity consumption
  6. Upgrade Lighting: Replace halogen or incandescent bulbs with LED bulbs using up to 90% less electricity
  7. Insulate Effectively: Insulate attic or walls; high upfront cost but drastically reduces heat loss with long-term ROI

Frequently Asked Questions About Understanding Your Utility Bill

Your electricity bill is calculated by multiplying your usage in kWh by your unit rate, then adding the annual standing charge, the PSO levy, and VAT at 9%. For example, 4,200 kWh at 34.75c/kWh with standing charges produces an annual bill of approximately €1,710.
An actual reading (marked "A" on your bill) is taken directly from your meter by ESB Networks or submitted by you. An estimated reading (marked "E") is calculated by your supplier based on previous usage patterns and may result in over- or under-billing.
Contact your energy supplier immediately. The CRU requires suppliers to assist customers in financial difficulty, offer alternative payment methods, and adhere to the Energy Engage Code which promises no disconnection while working toward a solution.
The MPRN (Meter Point Reference Number) is a unique identifier for your electricity connection point. It is tied to your property address and changes when you move. You need your MPRN when switching electricity suppliers.
Key strategies include switching energy suppliers annually, installing a smart meter for accurate readings, lowering your thermostat by 1°C to reduce heating costs by up to 10%, and comparing the market for the best rates.
