The switching timeline, step by step
Day 0: You apply
After comparing tariffs on our partner platform and choosing a deal, you submit your application online. This usually takes a few minutes and requires your address, current supplier details, and payment information if you're setting up a Direct Debit.
The 14-day cooling-off period begins
As soon as your contract is confirmed, a statutory 14-day cooling-off period starts. During this window, you can cancel the switch without any penalty, for any reason. Many suppliers won't actually begin the switch process until this period has passed or you've actively confirmed you want to proceed sooner; though some will start preparations in the background.
Around day 14 to 17: The switch begins
Once the cooling-off period has passed (or you've waived it), your new supplier contacts your current supplier to coordinate the handover. This is handled entirely between the two suppliers; you don't need to contact your old supplier yourself.
Switch day
On the agreed switch date, your new supplier officially takes over your account. Your gas and electricity continue flowing exactly as before; there's no visit required, no interruption, and nothing changes physically at your property. It's worth taking a meter reading on this day if you can, as it gives you a record to compare against your final bill from your old supplier and your first bill from the new one.
After the switch
Your old supplier will send a final bill based on a meter reading taken around the switch date (either an actual reading you provide, a smart meter reading, or an estimate). Your new supplier will set up your account and you'll start receiving bills or Direct Debit payments on your new tariff.
Typical overall timeline
Adding it up, most switches complete within about two to three weeks of application: roughly 14 days for the cooling-off period (if used in full), followed by a few working days for the switch itself. Some suppliers can move faster if you choose to waive the cooling-off period, and the actual transfer once it begins often completes within about five working days.
It's worth noting that timelines can occasionally extend if there's a query to resolve; for example, if your previous supplier raises an objection due to an outstanding balance, or if there's a mismatch in the property or meter details.
What can cause delays
A few things can slow a switch down:
If your switch is taking longer than expected, your new supplier is the best first point of contact, as they're managing the process on your behalf.
- Outstanding debt to your current supplier above the threshold they allow for switching
- Incorrect property or meter details entered during the application
- Recently switched; some suppliers have a minimum period before you can switch again
- Objections raised by your current supplier, which they're allowed to do in limited circumstances, such as an unresolved query on your account
