Deemed rates are typically far more expensive than contracted rates
When you move into premises and use energy without a contract, the supplier charges you its deemed rates. These are usually the highest rates a supplier offers, and they apply from the day you move in. The sooner a contract is in place, the less you pay at deemed rates.

Already moved in? Your contract can start from the day you did.
Many businesses are not aware they have been placed on deemed rates until the first bill arrives, which can be several months after moving in. In many cases we can arrange a contract backdated to the date you took over the premises, so that energy is billed at your contracted rate.
Without a backdated contract, every unit used between your move-in date and the start of a new contract is charged at the supplier's deemed rate. With a backdated contract, the supplier reissues those bills at the contracted price, and the difference is credited to your account.
When businesses contact a supplier directly, the contract will usually start from the date it is agreed, and the period already spent on deemed rates is not rebilled. Through our supplier relationships we are often able to arrange backdated start dates that are not offered to customers going direct.
How a backdated contract works
- The day you moved inMove-in date confirmed
Your lease start or completion date becomes the start date of your account.
- Same dayOpening reading agreed
We confirm the meter reading from the day you became responsible.
- When the contract is agreedContract dated from move-in
Where the supplier allows, your contracted rate applies from your move-in date rather than the day you sign.
- On your next billDeemed charges rebilled
Any bills issued at deemed rates are reissued at your contracted price and the difference is credited.
Backdating depends on the supplier, your meter type and how long you have been in occupation. We will confirm what is possible before you agree to anything.
What backdating can mean for your first bills
See an illustrated example and estimate the difference for your own usage.
Is the energy bill still in the previous occupier's name?
When you move in, the account usually stays in the name of the last occupier, or the supplier addresses bills to "The Occupier". Until the account is in your business's name, you cannot properly pay the bills, reclaim the VAT or show the costs in your accounts.
We register your business as the new occupier with the supplier, agree the opening meter readings and set up a contract in your name.
Getting the bill into your nameHow we set up your new contract
Suppliers can take up to 10 working days to review proof of occupancy. We manage the change of tenancy and your new contract at the same time, so you spend as little time as possible on deemed rates.

Common issues when moving into new premises, and how we help
Deemed rates
Suppliers apply their default out of contract rates from the day you move in. These are typically higher than a negotiated contract.
We can arrange a contract the same day and backdate it in many cases.
Proof of occupancy
Suppliers may ask for a tenancy agreement, completion statement, business rates bill or landlord letter, and can take up to 10 working days to review it.
We confirm which documents the supplier needs and submit them on your behalf.
Delayed transfers
Issues with the outgoing tenant's account can delay a change of tenancy and keep the new occupier on deemed rates.
We work with the supplier to progress the change of tenancy.
Previous tenant's bills
Estimated readings and incorrect start dates can lead to bills for energy used before you moved in.
We confirm your start date and opening readings so you only pay for the energy you use.
Credit checks and deposits
New companies and businesses with limited credit history may be asked for a security deposit or guarantee.
We will always work to avoid a security deposit, and our wide range of suppliers means we can nearly always accommodate this.
Time spent with suppliers
Moving premises involves a lot of work, and contacting suppliers can take time away from running your business.
Your dedicated account manager deals with suppliers for you.
What suppliers need from a new occupier
Under Ofgem guidance, the new occupier should tell the current supplier as soon as possible, even if they are discussing contracts with other suppliers. The supplier then reviews your evidence within 10 working days and either opens your account, rejects it, or asks for more information.
Energy contracts are linked to the meter rather than the business. The previous tenant's contract does not transfer to you, and you are not responsible for their debt.
What to have ready
- Meter readings
- Opening readings from the day you became responsible. A dated photo is useful.
- Move-in date
- Your lease start or purchase completion date.
- Proof of occupancy
- A lease, tenancy agreement, completion statement or title deeds.
- Business details
- Full business name, structure and company number if limited.
- Current supplier
- If you know it. If not, we can find it from the address.
- Supplier letters
- Anything mentioning deemed, out of contract or variable rates.
If you do not have everything yet, you can still request a quote and we will help with the rest.
What if I don't know who my supplier is?
This is very common when moving into new premises. It is important not to wait until you find out. From the day you move in, energy used at the property is billed at the supplier's deemed rates, and the longer it is left the more it is likely to cost.
You do not need to know your supplier to request a quote. If you can send us the meter serial number, we can look up your supply on the national electricity and gas databases for the most accurate results. If you do not have it, we can use your address instead. We then find your meter numbers and current supplier, contact the supplier and arrange the change of tenancy for you.
Ask us to find your supplierThe Meter Point Administration Number is a unique reference for your electricity supply. It is usually shown on a bill as a box of 21 digits over two lines, often starting with an S. The 13 digit bottom line is the core MPAN, which is the part suppliers use.
The Meter Point Reference Number identifies your gas supply. It is usually between 6 and 10 digits and is shown on gas bills, sometimes labelled M number or meter point reference.
Printed on the meter itself. If you have no bills from the previous occupier, a photo of the meter or its serial number is often enough for us to find your supply.
Where to find your meter serial numbers, MPAN and MPRN
The serial number is printed on the front of the meter, usually below or beside the display and often next to a barcode. It is typically a mix of letters and numbers, for example S12A345678. Smart meters show it on a label on the front.
The serial number is on a plate or sticker on the front of the meter, often near the technical details. Gas meters are usually in a meter box outside, a cupboard or a basement.
Look for a box marked "Supply number" or "MPAN", usually on the first or second page of an electricity bill. The MPRN is shown on gas bills as a single number, without the box layout.
Send us a photo of each meter or the numbers above with your quote request and we will do the rest.
Support for new businesses and those with limited credit history
Being a newly incorporated company or having a low credit score does not prevent you from getting a contract, although it can reduce the number of suppliers available. Each supplier uses its own credit criteria, so we compare options across the market and take any deposit or guarantee into account when recommending a contract.
Because we work with a wide range of suppliers, we can nearly always find one that will offer you a contract without a security deposit.
Suppliers that accept new businesses
We know which suppliers currently accept businesses with no trading history.
Deposits and payment terms
We compare deposit, guarantee and Direct Debit requirements alongside prices.
Sole traders and partnerships
We can help sole traders and partnerships, where suppliers may also consider personal credit.
Moving off deemed rates
A fixed contract is usually better value than remaining on deemed rates.
