Running a café in Cardiff, a print shop in Leeds, or a warehouse in Manchester? Then electricity and gas are probably your second- or third-largest bills after wages and rent. The residential market in Britain is protected by a price cap; the commercial market is not. Prices change daily, contracts are bespoke, and a wrong decision can lock your business into paying thousands of pounds more than you need to.
This guide from Galaxy Region Utilities (GRU) explains, step by step, how the U.K. business energy market really works, why prices rise or fall, and how you can secure the very best contract for your company. By the end you will know who does what, which tariff suits you, how to spot hidden costs, and the quickest, safest way to cut your bills.
1. WHY BOTHER LEARNING THIS STUFF?
-
Energy is a controllable cost: understand it and you can cut it.
-
Suppliers quote very different rates on the same day: you need to know why.
-
Small mistakes on invoices (wrong VAT, meter estimates) can cost hundreds.
-
The government’s net-zero targets will soon require every business to show its carbon plan; knowledge now means compliance later.

3. FROM POWER STATION TO PLUG—THE JOURNEY
-
Generation – Electricity is produced at power stations and wind farms.
-
Transmission – National Grid moves high-voltage power across the country.
-
Distribution – Regional DNOs step voltage down and deliver it to streets.
-
Metering – Your meter records consumption (half-hourly or standard).
-
Billing – Your chosen supplier invoices you based on meter data.
For gas, swap National Grid for the National Transmission System and add Gas Distribution Networks, but the chain is similar.
4. BUSINESS TARIFF TYPES EXPLAINED
| Tariff | Good for | Pros | Cons |
|---|---|---|---|
| Fixed rate (1–5 yrs) | Budget certainty | Locks unit rate and standing charge | No benefit if market drops |
| Variable / pass-through | Risk-tolerant users | Rates may fall in a weak market | Can spike suddenly |
| Blend & extend | Mid-contract during high prices | Smooths cost over longer term | Extends commitment |
| Time-of-use | Night-shift factories, EV fleets | Cheap off-peak rates | Peak rates high |
| Flexible (basket) | Large multi-site groups | Access wholesale trading | Needs constant management |
5. THE HIDDEN COSTS ON YOUR BILL
-
VAT errors – Most businesses should pay 20 %, but some qualify for 5 %.
-
Climate Change Levy charged twice – Often forgotten when you move to a green tariff.
-
Estimated reads that exceed reality – Overbilling is common without smart meters.
-
Capacity charges – Half-hourly meters incur extra fees; make sure they match your actual kVA demand.
-
Historic corrections outside 12 months – Suppliers can only back-bill one year; challenge anything older.
Galaxy Region Utilities recovers an average £482 per site when we perform a full bill-validation audit.

8. FREQUENTLY ASKED QUESTIONS
Is there a price cap for business energy?
No. Only households are protected. Businesses must negotiate or risk high rates.

Commercial contracts are binding. You can blend & extend or pay an exit fee, but you cannot simply walk away.
How long does a switch take?
Four to six weeks, and there is no downtime—electricity and gas keep flowing.
