Postcode-only
We hold ECOES and Xoserve data licences, so we retrieve your supply details from your postcode alone. No bill upload. No meter reference hunt.
One flat fee
1p per kWh, shown as its own line on your contract. No commission buried in your unit rate. Calculate it in your head.
The problem
Every energy broker wants your phone number.
We just want your postcode.
Commercial energy has always been a phone-first market. You enquire, someone calls, and you sit through a pitch, a close, and a commission line buried in the small print.
Meanwhile, the consumer comparison sites you'd use at home can't help your business — because without ECOES and Xoserve licences, they have to ask you to upload a bill or type in a meter reference number you've never seen. That friction stops most people at the first step.
We built BuyEnergyOnline.uk to close that gap. One postcode. We retrieve your supply details. You see your options. You decide. No one calls unless you ask them to.
How it works
Three steps.
Under five minutes.
No phone call.
Most business energy comparison ends in a sales call. This doesn't.
Postcode
Enter your business postcode and pick your address. Behind the scenes — using our ECOES and Xoserve licences — we retrieve your gas and electricity supply details automatically. No MPAN, no bill, no meter reference to hunt for.

Why this works
Other comparison sites ask you to upload a bill.
We already hold the data.
BuyEnergyOnline.uk runs on Telnergy's regulated infrastructure — including active ECOES (electricity) and Xoserve (gas) data licences.
That's the same supply-point data your current supplier and network operator use to manage your account. You've simply never had direct access to it. Now you do.
The result is a self-serve business energy tool that genuinely works like a consumer one — because the underlying data problem has been solved. As far as we know, no other self-serve business energy platform in the UK offers it.

You could wait for a cold call.
Here's the difference.
Sometimes a phone broker lands a competitive deal. The problem is you've no way to know — because you only ever saw their shortlist. Seeing the wider market is the only reliable way to tell whether a price is genuinely good.

"I'd been meaning to look at our energy contract for two years. The renewal snuck up and we were stuck on the rollover rate. I entered our postcode and had three quotes in front of me in about four minutes. Signed the same day."— Director, accountancy practice · Dorset · 8 staff
"What I liked was that nobody rang me. I hate the whole commercial energy phone game. Clear fee, contract by email, about fourteen percent off our old unit rate. Straightforward."— Owner, hospitality business · Hampshire · 22 staff
"Our accountant mentioned it. We were out of contract and hadn't noticed. Switched within a week — and the battery storage referral turned out to be worth more than the switch."— Operations manager, manufacturing · Wiltshire · 31 staff
After you switch
Self-serve to switch.
Not self-serve when
something goes wrong.
Switching is the easy part. The real test of an energy partner is what happens afterwards — when a bill arrives that's three times what it should be, or a supplier pursues a charge that isn't owed.
That's where being operated by a 24-year regulated consultancy matters. Telnergy Ltd is DRO enrolled (ADR Ref: E3561), Energy Institute affiliated, and handles supplier billing disputes, back-billing challenges, and Ombudsman escalations as a matter of routine. A pure comparison site can't do that. A call-centre broker won't.
We track your renewal.
A reminder lands 90 days before your contract ends. You'll never silently roll onto an out-of-contract rate again.
We handle the switch end to end.
Confirmations at each stage. We only contact you if something genuinely needs your input.
We fight your corner.
If a supplier bills you incorrectly or pursues a charge you don't owe, our regulated dispute process is behind you.
Ask Joules
Not sure where
to start? Ask Joules.
Business energy comes with a lot of awkward questions — what an MPAN is, whether you're still in contract, what that 1p fee actually means on your bill. Joules, our energy assistant, answers them in plain English, any time, without a phone call.
Joules explains things. Your contract and Letter of Authority always go through our regulated process.
The market is changing
Ofgem is coming for
rogue brokers.
We welcome it.
Mandatory TPI licensing is coming to the UK commercial energy market. When it lands, unlicensed and unregistered intermediaries won't be able to operate legally.
Telnergy has been Ofgem registered since 2002 and sits on the Ofgem TPI Working Group that helped shape the consultation. We're DRO enrolled and Energy Institute affiliated. We have nothing to fear from licensing. We're looking forward to the market it will produce.
