Supplier Comparison FAQs
Quick answers to common questions about comparing and switching business energy suppliers.
How do I know which energy supplier is right for my business?
We compare all major UK business energy suppliers side-by-side, showing pricing, contract terms, and Trustpilot ratings so you can make an informed choice
Can I switch both gas and electricity with you?
Yes. You can switch either one or both together. We’ll help you find the best deal for your business across 28+ suppliers.
What happens if I'm out of contract with my supplier?
Out-of-contract (OOC) rates are usually much higher. Our comparison tool links directly to each supplier’s OOC rates so you know what you’d be paying — and how much you could save by switching.
Do all suppliers require smart meters?
Not all, but many do. We’ll flag suppliers that require a smart meter so you can decide what works best for your site.
How long does it take to switch suppliers?
Most business switches complete within 2–5 working days with no downtime. We handle all the admin for you. We therefore recommend agreeing a contract at least 2 weeks before your current contract expires to ensure you don't fall into Out-of-contract rates.
You can also check our 'When to Renew' timing advice to capture the best prices at the best times
Will I get a quote from all the suppliers you work with?
Not always. Each supplier has their own rules on meter types, regions, and usage levels. We’ll only show you the options that apply to your business. For example, Drax only provide electricity quotes, while TEM only supply half-hourly meters.
