Consumption focused on business hours, often with a 2.0TD supply.
Capacity, schedule and fixed cost
Personalised business comparison
Compare business electricity tariffs using your real consumption
There is no single cheapest business tariff. We analyse your bill, capacity and usage pattern so available offers can be compared on like-for-like terms.

Why we do not publish a misleading price table
Business offers do not work like a public list of household prices. Two companies on the same street can receive different terms.
Annual volume, load curve, contracted capacity, time periods and contract length influence the quote. Larger users can often negotiate terms that never appear in public tariffs.
What determines a business offer
We normalise these inputs before comparing proposals.
Total annual kWh consumption
Contracted capacity and recorded maximum demand
2.0TD, 3.0TD or high-voltage access tariff
Hourly load profile and period usage
Seasonality and opening hours
Fixed, indexed or blended pricing
Reactive energy and other penalties
Contract length, lock-in and payment terms
Number of supplies or business locations
The right contract depends on the business
Profiles give us a starting point, but the final recommendation is always based on bill data.
Bar or café
Continuous refrigeration, kitchen equipment and service peaks.
Load profile and peak demand
Restaurant
Energy-intensive cooking, cooling and refrigeration.
3.0TD, capacity and periods
Hotel
Long operating hours, seasonality and multiple high-load systems.
Volume, seasonality and optimisation
Large or multi-site user
Enough volume to request negotiated terms and consolidate supplies.
Tendering, risk and contract terms
How we compare offers fairly
A low advertised kWh rate can cost more after capacity charges, margins, lock-ins and penalties are included.
- 1
Read the bill
We extract consumption, capacity, access tariff, periods and potentially avoidable costs.
- 2
Understand the profile
For larger users we may request more bills or interval data rather than relying on one month.
- 3
Compare like with like
We estimate each proposal using the same consumption and flag lock-ins, revisions and conditions.

Explain the recommendation
You receive a clear comparison with assumptions and risks visible before you decide.
Fixed, indexed or blended pricing
We do not recommend one structure by default. The choice depends on the business's risk tolerance and usage pattern.
Fixed price
Greater budget certainty, but contract length, price reviews and lock-ins still need checking.
Indexed price
Tracks the market plus a margin; it can be competitive but passes volatility to the business.
Blended structure
Can combine price cover with market exposure for larger consumption profiles.
Larger users need a different comparison
Higher volume can improve negotiating power, but the unit rate is not the whole deal. Guarantees, payment terms, tolerances, renewals and market exposure also matter.
We therefore never present another customer's quote as universally available. We request terms suited to the supply and document the assumptions used.
Start with a recent bill
We will review consumption, capacity and possible penalties before comparing the options available for your business.

Business electricity switching questions
Which electricity supplier is cheapest for a business?
There is no universal answer. It depends on each supply's consumption, capacity, load profile, access tariff and contract terms.
Can a business switch supplier without losing power?
A supplier switch is an administrative process and normally does not interrupt the electricity supply.
Why do larger businesses obtain better prices?
Volume can unlock negotiated offers, although guarantees, lock-ins, capacity costs and market risk must also be compared.
What do you need to compare offers?
A recent bill is normally enough for an initial review. Larger or seasonal users may need several bills or interval consumption data.
Does the comparison cost anything?
