Running a small business means every pound of overhead matters. Unlike large corporations with dedicated procurement teams and the volume to command the lowest market rates, small business owners often have to navigate the commercial energy market alone — and without the time to do it properly. The result is that many smaller companies end up on contracts that were never designed with their needs in mind, paying rates that a little comparison could easily improve. Finding the best energy deals for small business doesn't require specialist knowledge or hours of research. It requires the right approach, the right timing, and access to a platform that does the heavy lifting for you.
This guide covers exactly that — how to set up your energy account, what to consider before signing any deal, and clear answers to the questions small business owners ask most often about commercial energy.
Why Small Businesses Often Pay More Than They Should
The commercial energy market in the UK operates without a price cap for business customers. That means pricing is entirely market-driven — and the rate you pay is a direct reflection of when you last compared, who you compared with, and how much attention you paid to the terms you agreed to.
Small businesses are particularly vulnerable to two common pitfalls. The first is auto-renewal: contracts that roll over automatically onto a new — often more expensive — deal when the existing one expires, without the business owner actively choosing to renew. The second is deemed rates: the above-market tariffs suppliers charge when a contract expires without any new agreement in place.
Both of these situations are entirely avoidable. And for small businesses, avoiding them is one of the most straightforward ways to reduce operating costs without cutting services or staff.
How to Set Up the Best Energy Deal for Your Small Business
Getting set up with a competitive energy supplier is simpler than most small business owners expect. Here's a clear step-by-step process:
- Gather your current energy details. You'll need your electricity Meter Point Administration Number (MPAN) and your gas Meter Point Reference Number (MPRN) if you use gas, your annual consumption in kWh for each fuel, your current supplier's name, and your contract end date. These details are all on your existing energy bills.
- Know your consumption pattern. Small businesses often have more variable consumption than larger operations — seasonal spikes, irregular hours, or premises left unused at weekends. Understanding your usage profile helps you choose the right tariff type and avoid paying for capacity you don't use.
- Start comparing three to six months before your contract ends. Timing is everything in commercial energy. Starting early removes the pressure of an approaching deadline and gives you the leverage to compare properly rather than scramble for any available deal at the last minute.
- Use a specialist small business energy comparison platform. Platforms like SmartBiz Utility allow you to compare live quotes from multiple suppliers simultaneously, filtered by your consumption profile and location. This saves hours of individual research and ensures you see the full market — not just one supplier's offering.
- Compare total annual cost across all quotes. Look beyond the unit rate. Factor in the standing charge, contract length, and any additional fees to calculate the true annual cost of each deal. The cheapest unit rate doesn't always produce the lowest bill.
- Choose a contract length that suits your situation. Shorter contracts offer flexibility; longer ones can lock in a better rate when the market is favourable. For small businesses with uncertain growth plans or potential premises changes ahead, a 12 to 24-month contract often strikes the right balance.
- Confirm your new contract in writing. Once you've selected your supplier, the switch is largely managed on your behalf. Confirm all terms in writing, retain a copy of your contract, and take meter readings on the day your new supply begins.
- Set a renewal reminder straight away. Immediately after confirming your new deal, put a calendar alert for three months before the contract end date. This simple habit keeps you permanently ahead of the renewal cycle.
Key Considerations for Small Businesses Comparing Energy Deals
Small businesses have specific needs that differ from larger commercial operations. Here's what deserves particular attention when evaluating your options:
- Unit rate and standing charge balance. For small businesses with lower consumption, the standing charge — a fixed daily cost regardless of usage — can represent a disproportionately large share of the total bill. Pay close attention to this component and calculate the full annual cost, not just the per-unit price.
- Fixed tariffs for budget certainty. Fixed-rate contracts lock your unit price for the contract term, making monthly costs predictable. For small businesses managing tight cash flow, this predictability is often more valuable than the potential savings of a variable tariff that could rise unexpectedly.
- Micro-business protections. If your business uses fewer than 100,000 kWh of electricity or fewer than 293,000 kWh of gas annually, Ofgem classifies you as a micro-business. This entitles you to specific contractual protections — including clearer notice requirements, the right to exit without penalty during a defined window before your contract ends, and stronger obligations on suppliers around billing transparency.
- Auto-renewal and notice period clauses. Always read the auto-renewal terms in any commercial energy contract. Some suppliers require 30, 60, or even 90 days' notice before the contract end date to avoid being automatically rolled onto a new deal. Missing this window is one of the most common and costly mistakes small businesses make.
- Green energy options at competitive rates. Small businesses increasingly want to demonstrate environmental responsibility, and green energy tariffs have become more affordable as the renewable market has matured. If sustainability matters to your brand or customer base, ask specifically about REGO-backed electricity tariffs — many are now comparable in price to standard options.
- Ease of account management. For small business owners managing multiple responsibilities, simplicity matters. Look for suppliers with straightforward online account portals, clear digital invoicing, and responsive customer support that doesn't require long hold times or repeated chasing to resolve basic queries.
- Dual-fuel deals. If your business uses both gas and electricity, some suppliers offer combined deals that simplify billing and occasionally offer better combined pricing. Compare dual-fuel options alongside standalone contracts to see which delivers better overall value for your specific consumption mix.
- No hidden charges. Some commercial energy contracts include fees for paper billing, late payment, exceeding consumption thresholds, or early exit. Always read the full terms and conditions — not just the summary — before signing anything.
Frequently Asked Questions
Are there energy deals specifically designed for small businesses?
Yes. Many commercial energy suppliers offer products tailored to SMEs and micro-businesses, with simpler contracts, lower minimum consumption thresholds, and more accessible account management. A specialist comparison platform can filter results by consumption level to surface the deals most relevant to your business size.
How much could I save by switching energy suppliers as a small business?
Savings depend on your current rate, consumption level, and the deals available when you compare. Small businesses that haven't reviewed their energy contract in over a year — or that have rolled onto a deemed rate — often find the most significant savings, sometimes running into several hundred pounds annually even at modest consumption levels.
What is the best contract length for a small business?
Most small businesses benefit from 12 to 24-month fixed contracts. These provide enough term to lock in a competitive rate while keeping the renewal cycle frequent enough to take advantage of market improvements. Longer contracts can offer lower rates but are riskier if your premises, usage, or business circumstances are likely to change.
Can I switch energy suppliers if I work from home?
If you run your business from home, your energy supply may be classified as domestic rather than commercial, which means domestic tariffs and Ofgem's price cap protections may apply. If you have a separate commercial premises — even a small office or unit — that supply falls under commercial energy rules and you can compare business tariffs freely.
What happens to my energy supply during a switch?
Nothing changes physically. Your gas and electricity continue to flow through the same infrastructure throughout the switching process. Only the billing and account management transfer to the new supplier. Electricity switches typically complete within five working days; gas switches take up to 21 days.
How do I know if I'm on a deemed rate?
If your energy contract has expired and you haven't actively signed a new one, you're likely on a deemed rate. You can confirm this by checking your most recent bill or contacting your supplier directly. Deemed rates are almost always significantly above the competitive market, so switching away from one should be a priority.
Is it possible to get a green energy deal as a small business?
Yes. Green electricity tariffs backed by Renewable Energy Guarantee of Origin (REGO) certificates are widely available in the commercial market and are increasingly competitively priced. Green gas options backed by biomethane are also available from a growing number of suppliers. A comparison platform can show you green options alongside standard tariffs so you can assess the cost difference directly.
