Business Electricity Rates UK — compare and switch with confidence
Independent comparison of business electricity prices from a UK-wide panel of suppliers. From single-rate micro-business deals to half-hourly manufacturing contracts, we match the tariff to your actual load.
What affects your business electricity rate?
Business electricity prices per kWh are made up of several moving parts. Understanding them helps you spot a genuinely cheap business electricity supplier from one that just quotes an eye-catching headline unit rate.
- Wholesale energy costs — typically 40-60% of your unit rate. Suppliers buy in bulk and pass movements on.
- Network charges — the cost of moving electricity through the grid to your meter, set by your regional DNO.
- Environmental & social obligations — Contracts for Difference, Renewables Obligation, Capacity Market and similar levies.
- Supplier operating costs & margin — billing, credit, hedging and profit.
- Your consumption profile — total kWh, load shape (day vs night, weekday vs weekend) and creditworthiness.
Small vs medium vs large business electricity usage
Suppliers price your business against usage bands. Getting into the right band unlocks materially cheaper business electricity rates.
- Micro / small business — under 25,000 kWh a year (small offices, high-street shops, single cafés).
- Medium business — 25,000-100,000 kWh (busy pubs, small factories, small-portfolio retailers).
- Large business — 100,000+ kWh, usually on a half-hourly (HH) meter (manufacturing, warehousing, cold storage, large multi-site).
Fixed vs variable vs renewable business electricity tariffs
Choose the tariff type that matches your budget appetite and sustainability goals — not just the lowest headline rate.
- Fixed-rate — unit rate and standing charge locked for 1-4 years. Best for budgeting certainty.
- Variable-rate — moves with wholesale prices; benefit if prices fall, exposed if they rise.
- Renewable / REGO-backed — 100% renewable-matched electricity, often within 1-3% of standard pricing.
- Half-hourly (HH) — bespoke pricing built from your actual 30-minute consumption profile; essential above 100 kW peak demand.
- Deemed / out-of-contract — the expensive default if you don't renew on time. Avoid.

Business electricity FAQs
The questions UK businesses ask most about business electricity prices per kWh, standing charges, MPANs and switching.
What is the average business electricity rate per kWh in the UK?
Business electricity unit rates typically sit in the range of 22p-32p per kWh in 2026, with a daily standing charge of roughly 40p-70p. Rates vary significantly by region, business size, meter type and contract length — the only reliable rate is a live quote for your specific meter.
What's the difference between a small, medium and large business electricity user?
As a working guide: small businesses use under 25,000 kWh a year (small offices, shops), medium users 25,000-100,000 kWh (busy hospitality, small industry), and large users above 100,000 kWh often on half-hourly metering (manufacturing, cold storage, large multi-site retail).
What is a standing charge and why do I have to pay it?
The standing charge is a fixed daily fee that covers your connection to the electricity network — meter reading, maintenance and grid access. It applies even if you use zero units in a day. Some no-standing-charge tariffs exist but usually build the cost into a higher unit rate.
Can I get a business electricity tariff with no standing charge?
Yes, a few suppliers offer no-standing-charge business electricity tariffs, mostly for very low-usage sites like unmanned units. For most businesses the unit rate is higher, so a standard tariff usually works out cheaper overall — we'll model both for you.
What is an MPAN number and where do I find mine?
Your MPAN (Meter Point Administration Number) is a 21-digit reference — often shown in a grid marked 'Supply Number' or 'S' on your bill — that uniquely identifies your electricity meter. You'll need it when switching, and we can look it up for you if it's missing.
Is business electricity cheaper than domestic electricity?
Generally unit rates for business electricity can be lower than domestic rates because businesses buy in larger volumes and on longer contracts. However business bills attract 20% VAT by default (vs 5% for domestic) so the total bill differs.
How is VAT applied to business electricity bills?
Business electricity is charged 20% VAT as standard. You may qualify for the reduced 5% rate if you're a charity, non-profit, or your site uses under 33 kWh per day / 1,000 kWh per month. You'll need to complete a VAT declaration with your supplier.
What is a half-hourly meter and do I need one?
Half-hourly (HH) meters record consumption every 30 minutes and are mandatory for sites with peak demand above 100 kW, and increasingly for many medium businesses. They enable more accurate — and often cheaper — pricing, but tariffs are quoted differently, with separate day/night/peak rates.
