Learn about different energy tariffs available in the UK and how Fraser Bond helps property owners select the best options for their real estate investments.

Introduction

Energy tariffs directly impact the operating costs and profitability of real estate assets.
Whether you manage residential flats, commercial units, or large investment portfolios, understanding national energy tariffs is crucial for securing competitive utility contracts, controlling service charges, and maximizing tenant satisfaction.
This guide provides a complete overview of national energy tariffs in the UK, the types available, and strategic advice on choosing the best tariff for your properties.


What Are National Energy Tariffs?

National energy tariffs refer to the structured rates that energy suppliers charge for electricity and gas supply across the UK.
Suppliers set these tariffs based on:

  • Wholesale energy market prices

  • Government levies (e.g., green taxes)

  • Infrastructure costs

  • Operational overheads

Ofgem, the UK’s energy regulator, oversees tariff transparency and enforces the Energy Price Cap on standard variable rates to protect consumers.

In a deregulated market like the UK, consumers — including landlords and businesses — can choose their supplier and tariff plan freely, enabling competition and better service offerings.


Types of National Energy Tariffs

1. Fixed-Rate Tariffs

Features:

  • Unit rates (pence per kWh) and standing charges remain unchanged for a set term (typically 12–24 months).

  • Protection against wholesale market price rises.

Ideal For:

  • Landlords budgeting operational costs across multi-unit portfolios.

  • Investors needing cost stability for service charge forecasting.

Important Considerations:

  • Early exit fees may apply if you switch suppliers before the term ends.


2. Variable-Rate Tariffs

Features:

  • Prices can rise or fall depending on wholesale energy market movements.

  • Typically no fixed-term contract, offering greater flexibility.

Ideal For:

  • Property owners willing to risk price fluctuations for the ability to switch suppliers easily.

Important Considerations:

  • Bills may spike during periods of high demand (e.g., winter).


3. Dual Fuel Tariffs

Features:

  • Bundles both electricity and gas under a single contract.

  • Often includes discounts or simplified billing.

Ideal For:

  • Managing mixed-use or residential properties where tenants require both utilities.

  • Simplifying portfolio billing.


4. Economy 7 and Economy 10 Tariffs

Features:

  • Offer cheaper electricity during night-time hours (Economy 7) or split across night and day (Economy 10).

  • Requires special meters.

Ideal For:

  • Properties with storage heaters or high overnight energy use.

Important Considerations:

  • Daytime rates are significantly higher; careful tenant communication is critical.


5. Green Energy Tariffs

Features:

  • Electricity sourced from renewable energy (wind, solar, hydro).

  • Gas may be partially offset by carbon credits or renewable biomethane.

Ideal For:

  • Eco-conscious developments appealing to sustainability-minded tenants.

Important Considerations:

  • May have slightly higher rates, though competitive green tariffs are increasingly available.
