Difference Between Gas and Power Supply – A Guide for UK Property Owners

Introduction

In the UK property market, understanding the difference between gas and power (electricity) supply is more important than ever. As the country transitions toward cleaner energy systems and stricter regulations, property developers, landlords, and investors must make informed decisions about which energy sources power their assets—and how those choices affect costs, compliance, and long-term value.

Fraser Bond breaks down the fundamental distinctions between gas and electricity supply and explains how these differences impact property strategies in today’s energy-conscious environment.

What Is Gas Supply?

The gas supply system delivers natural gas—primarily methane—to buildings for heating, hot water, and cooking. In the UK, gas is:

• Extracted from the North Sea or imported

• Transported through the National Gas Transmission System (formerly part of National Grid)

• Distributed to end users via Gas Distribution Networks (GDNs)

• Supplied by retail gas suppliers like British Gas or EDF

Gas is typically used in:

• Traditional boilers and heating systems

• Gas cookers and ovens

• Older residential stock and commercial kitchens

What Is Power Supply?

Power supply, commonly referred to as electricity, is the delivery of electrical energy used to operate lighting, appliances, cooling systems, EV chargers, and more. In the UK:

• Electricity is generated from a mix of fossil fuels, nuclear, and renewables (wind, solar, hydro)

• Transported via the National Grid’s high-voltage transmission network

• Distributed by local Distribution Network Operators (DNOs)

• Sold to customers by retail electricity suppliers like Octopus Energy, E.ON, or ScottishPower

Electricity powers:

• Lighting, refrigeration, air conditioning

• Heat pumps and electric radiators

• All-electric residential developments and smart homes

Key Differences Between Gas and Power Supply

Why It Matters in UK Real Estate

1. Development Planning

New developments must align with Future Homes Standard, which bans gas boilers from 2025. Electric-only homes are now standard in most planning consents. Developers must plan accordingly for:

• Heat pump integration

• Electric heating systems

• Smart grid connectivity

2. Energy Performance and Compliance

Electricity, especially from renewable sources, helps properties achieve higher EPC ratings and meet Minimum Energy Efficiency Standards (MEES). Landlords with gas-only systems may face:

• Retrofit costs

• Lower tenant appeal

• Regulatory penalties

3. Running Costs and Supply Volatility

Gas prices have historically been lower than electricity—but this is shifting. With electrification and solar adoption growing, long-term savings and stability may favour electric systems.

4. Tenant Demand

Modern tenants increasingly seek eco-conscious, low-carbon properties. All-electric homes with smart meters and EV charging points are more attractive in urban and build-to-rent markets.
