After you move

 

I've just moved business premises. What do I need to do?


When you move into new premises, the existing energy supplier to the property will put you on a deemed rate, unless you’ve made other arrangements in time.

Deemed rates are generally higher than the rate you get in a contract you've actively chosen.

Even if we supplied energy to your old premises, you'll need a new quote if you want a contract with British Gas business at your new premises.

You'll need to let us know at least 21 days before you move – earlier if possible.

Let us know you've moved by filling in this form:

Moving in form

Or you can call us on 0800 316 3093 (option 3) or request a callback

Mon-Fri 8am-6pm, Sat 9am-1pm,

We'll need to know:

  • Whether you want us to supply both gas and electricity
  • The meter reading, so you're not charged for energy you haven't used
  • What energy supplies the site has at the moment

How long does it take for my move to be processed?

It takes us around 10 working days to change your billing and supply details to your new address, so please allow this time before you call us.

If you've been waiting for over 10 working days, call us on 0800 316 3093 Mon-Fri 8am-6pm, Sat 9am-1pm.

I've recently moved in and I'm getting bills for the previous tenant/owner. What should I do?

Let us know you've moved by filling in this form:

Mon-Fri 8am-6pm, Sat 9am-1pm

We'll ask you to tell us the date you moved in and give us a current meter reading. We'll then put the account in your business name.

Why do you need my name on the account? I may not keep British Gas as my business energy supplier.


We need to know who has legal responsibility for the energy supply at the premises on any given date. An understanding of this makes any future switching process much easier.

When you move into new premises that we supply, if you haven’t agreed an alternative plan with us, you automatically enter into a ‘deemed’ contract and go onto our ‘deemed’ rates. This is because you’re ‘deemed’ to have taken the energy supply from us. Deemed rates are variable rates and are higher than our fixed price, fixed term rates.

We’d like to give you a quote for a fixed price contract for a defined period of time. This type of contract could help you benefit from lower prices and avoid price changes for the length of your contract. If you want to switch suppliers, you'll need to write to us 30 days before you want to leave and pay any outstanding bills.

You can read more about business energy price plans on our dedicated page.

Why am I still being billed for premises I’ve left?

This will be because your account is still open at those premises.

We can only close the account after you’ve told us you’re no longer legally responsible for the premises, and when you’ve paid the final bill or received any credits to your account.

If you’re still being billed, please contact us so we can help you close the account.

Why have you billed me from a different date to when I moved in/moved out?

We’ll bill you for the period when you’re legally responsible for the energy supply at the premises, which may not be the same as the date when you actually moved in or out.

In some cases the previous occupier, or the occupier’s representative, may have provided some information that may be incomplete, or that may be different to the information you’ve provided.

To help us bill you accurately and resolve any conflicts of information, we may ask for a photograph of your meter read or proof of tenancy e.g. a lease agreement, or a solicitor’s letter.

Why do you need my meter readings?

We use your meter readings to calculate your bill.

It means we can charge you for the energy you’ve used, rather than estimating your bill. It also means we can refund any credit balances we may owe you.

You should provide us with a meter reading as soon as you stop, or start, being legally responsible for the energy supply at your premises.

I've moved into premises supplied by British Gas business, what do I need to do?

How do I find out who supplies energy to my new premises?

The easiest way may be to ask the landlord or the previous owner/tenant. If they have a recent bill available, that could also give you the information you need.

If you can’t find out this way, visit the Energy Networks Association (ENA) website. There you’ll find all the details for finding out who supplies your business gas and electricity.
