Built for Metered LPG Estates

Calculate Your Metered LPG Costs Instantly

Our free LPG calculator is specifically designed for customers on metered LPG estates with communal bulk tanks — whether you're with Calor Gas, Flogas, AvantiGas, or another supplier. Get calculations for your heating and hot water LPG consumption based on your meter readings and boiler specifications.

Unlike generic energy tools, we account for LPG-specific conversion rates (1m³ = 3.85 litres), seasonal usage patterns, standing charges, and real-world boiler efficiency to give you the calculations.

Note: This calculator is for metered LPG systems only — not LPG bottles or cylinders. If you receive bills based on meter readings from a communal supply, this tool is for you.

* LPG gas meters are typically read in m³. The calculator converts m³ to litres (1m³ = 3.85 litres) and applies industry-standard energy conversion rates automatically.

Key Facts

1 m³ = 3.85 litres of LPG. Your meter reads in cubic metres.

1 litre = 7.08 kWh of energy output from LPG.

VAT on LPG is 5% — lower than the standard 20% rate.

Winter usage is typically 80% higher than summer months.

Metered LPG is typically 40–60% cheaper than bottled gas.

💰 Could You Save?

A price difference of just 5p per litre can save the average household £200–£400 per year.

Residents' associations can negotiate collectively for better bulk rates.

LPG Explained

Understanding LPG Costs for Metered Estates

LPG is typically 2–3× more expensive than mains gas. Here's what drives those costs and what you can do about it.

Why LPG Costs More

LPG requires specialised tanker transport, storage infrastructure, and has a smaller market than mains gas. These logistics costs are built into the unit rate, but metered estates benefit from bulk purchasing power to keep costs lower than bottled alternatives.

Metered vs Bottled LPG

Metered LPG on estates is typically 40–60% cheaper per litre than individual cylinders. You only pay for what you use, there's no heavy cylinder handling, and the supply is managed centrally with automatic bulk deliveries.

Seasonal Usage Patterns

Consumption varies dramatically with seasons — winter usage can be 80% higher than summer due to increased heating demands and reduced boiler efficiency in cold weather. Our calculator factors this into annual projections.
