What Gas Covers in Your Home
Gas is used primarily for:
Central Heating The largest component of your gas bill. Accounts for around 80% of typical gas usage. A well-maintained, efficient boiler and good insulation can significantly reduce consumption.
Hot Water Heating water for baths, showers, and taps. Typically accounts for 15% of gas usage. Consider taking shorter showers and fixing dripping hot taps to save.
Cooking Gas hobs and ovens account for only 3-5% of typical gas usage. Even if you cook frequently, most of your gas bill comes from heating.
Types of Gas Tariffs
Gas tariffs in the UK come in several main types:
Fixed Rate Tariff Lock in your gas price for 12-24 months. Your unit rate and standing charge stay the same throughout the contract, protecting you from wholesale market price rises. Particularly valuable for gas as winter demand can cause price spikes. Fixed tariffs usually have exit fees if you leave early.
Variable Rate Tariff Your rates can change at any time, usually following wholesale gas market prices. The advantage is flexibility with no exit fees, meaning you can switch whenever you find a better deal. However, you’re exposed to price rises, especially in winter.
Standard Variable Tariff (SVT) The default tariff you move to when a fixed deal ends. It’s usually the most expensive option and can increase at any time. Millions of UK households are on SVTs, often overpaying by £100+ per year. Always compare when your fixed deal ends.
Green Gas Tariff Two types:
- Carbon Offset: Your supplier invests in environmental projects to offset the carbon emissions from your gas usage
- Biomethane: A small percentage of renewable gas from food waste and organic matter is injected into the grid
Green gas tariffs are becoming more competitive in price.
Dual Fuel Tariff Get both gas and electricity from the same supplier for a discount (typically 3-10%). Simplifies bill management and often offers better value than separate supplies.
How to Save on Gas Bills
Pricentia suggests the most effective strategies to reduce your gas costs:
- Compare tariffs regularly: Never stay on a standard variable tariff
- Pay by direct debit: Saves 5-10% compared to other payment methods
- Get dual fuel: Combine gas and electricity for extra discounts
- Improve insulation: Loft and cavity wall insulation can save £hundreds per year
- Service your boiler: Annual service maintains efficiency and prevents breakdowns
- Lower thermostat by 1°C: Saves around 10% on heating bills
- Use heating controls: Programmable thermostat and thermostatic radiator valves prevent waste
- Switch when fixed deals end: Set reminder 49 days before to avoid SVT rates
Understanding Your Gas Bill
The gas bill comprises several components:
Unit Rate (variable) The price per kilowatt-hour (kWh) you consume. This is the main part influenced by your tariff choice and where you save money by comparing. Gas meters measure in cubic metres or cubic feet, which are converted to kWh on your bill.
Standing Charge (fixed daily cost) A daily fee for maintaining your connection to the gas network, usually 25-30p per day (£91-£110 per year). Set by your supplier but varies by region.
Distribution Charges Charges for transporting gas through the local network to your property. These are the same regardless of supplier but vary by the UK’s distribution zones.
VAT 5% on domestic gas (reduced rate). Standard 20% for business premises.
Pricentia compares the total annual cost, considering all components.
Average Gas Usage
UK household gas consumption varies significantly:
1-2 people (flat/small house): 8,000 kWh/year Typical annual bill: £480-£600
3-4 people (medium house): 12,000 kWh/year Typical annual bill: £720-£900
5+ people (large house): 17,000 kWh/year Typical annual bill: £1,020-£1,275
Usage increases significantly with:
- Older, poorly insulated properties
- Gas central heating (vs electric heating)
- Inefficient older boilers
- Higher thermostat settings
- Multiple bathrooms with power showers
Around 75% of annual gas is used between October and March for heating. Pricentia can estimate your usage even without bills, based on property type and household size.

Unlike traditional comparison websites, Pricentia offers a completely different experience:
AI Assistant on Telegram or WhatsApp You don’t have to interpret dozens of complex tariffs alone. The intelligent assistant contacts you on Telegram or WhatsApp, analyses your heating patterns and suggests the gas tariffs best suited to your needs.

Information Needed for a Quote
To get an accurate gas quote you’ll need:
- Recent gas bill (to know your annual kWh usage)
- Postcode (affects distribution charges)
- Current supplier and tariff (to calculate savings)
- Payment method (direct debit is cheapest)
- Property type (affects typical usage estimates)
With Pricentia you can start comparing even without all the information: the assistant will guide you step by step and estimate usage based on property size and household composition.
Switching Gas Supplier: How It Works
Switching to a new gas supplier is:
- Free: no cost for switching
- Simple: the new supplier handles everything including notifying your old supplier
- Seamless: no interruption to your supply
- No changes: same meter, no engineer visit needed (unless you want a smart meter)
- Quick: switching usually takes 2-3 weeks
Pricentia assists you through the entire switching process, from choosing the tariff to verifying activation and checking your first bill.
Gas Meters Explained
Standard Gas Meter Records usage in cubic metres (m³) or cubic feet (ft³). You submit readings manually or the supplier estimates. Can lead to inaccurate bills if readings aren’t regular.
Smart Gas Meter Automatically sends readings to your supplier, ensuring accurate bills. The in-home display shows real-time usage, helping you understand and reduce consumption. Installation is free.
Prepayment Gas Meter You pay for gas before using it via top-up. Traditionally the most expensive way to pay, but the gap is narrowing. Good for budgeting but less convenient than direct debit.
Pricentia compares tariffs for all meter types, helping you find the cheapest option for your situation.
