Reach businesses before they choose an energy supplier
A business that moves into premises without arranging a contract is put on its supplier's deemed rates until it signs one. That's the moment to call.
Why timing matters
Ofgem's advice to businesses says a business is put on a deemed contract automatically when it moves into new premises without arranging one, and that deemed rates are usually higher than negotiated contract rates (ofgem.gov.uk, checked 3 November 2026). So a new occupier has a reason to talk to you in its first weeks. A business that has changed hands is the same: the contract belonged to the last operator, and the new one needs a supply in its own name. Kitchens, workshops, care sites and factories use more power than most, and the file says which rows are those.
What we tell you
The moments that matter for you:
| Coming | A business is about to open: a licence applied for, a unit being fitted out, a new company set up to trade from the address. |
| Just moved in | A business has started at premises that had nobody in them: a new ratepayer, a new food business, a newly registered care home, nursery, surgery or garage. |
| Changed hands | A new operator at premises that were already trading: a pub, shop or care home under new ownership, often keeping the old name on the door. |
How to use it
Call the ones graded highest first. Every row says what happened, when, and what kind of business it is, so the first line of the call writes itself.
Coverage
The national registers cover every council in Great Britain. On top of those, 96 councils publish a business rates list we can use and 72 a licensing register (as of 3 November 2026), and more are added each week. Northern Ireland isn't in the file yet. Where the data comes from.
Built for selling within the rules: businesses not people, every row with its source and date, and nothing your team can't explain to someone who asks. How it's done.

Questions
Do you tell us the meter numbers?
No. Meter point numbers, bills and the current supplier aren't public, and we don't guess them. We tell you the business, the premises and what's happened there; your team does the rest.
How is this different from buying a list?
A list is a snapshot of businesses that exist. This is what changed yesterday: who moved in, who took over, who left. A bought list can't tell you any of that, and it's out of date the day it arrives.
How do you find them?
From public registers, read every day and kept, so we can see when something changes at an address. The sources are on the sources page. How we put them together is ours, and we don't publish it.
Is there personal data in it?
Almost none. The file is about businesses and premises: no director names, no home addresses. Where a business publishes only a named address on its own website, the daily file carries it in a marked column, as the privacy notice says; a sample never does. Where a phone number or a mailbox is public, we say where it came from.
Can we email or ring them?
Limited companies and LLPs can be emailed without prior consent under PECR, if you say who you are and give a way to opt out. Phone numbers are yours to screen against the TPS and CTPS before you ring.
What does it cost?
£250 a month for a region, or £1,000 a month for the whole of Great Britain, monthly, and you can stop at any month's end. The first two weeks are free, so your team can try it on real rows before paying anything.
Is the file exclusive?
Not the whole file, but you can have a head start. First look sends your trade's new rows for your region to you each morning, a working day before anyone else in your trade gets them, for one firm per trade and region: £375 a month for a region, or £1,500 a month for Great Britain, on the same terms.
