What switching actually changes (and what it does not)
Switching gas retailer changes who bills you and the rates you pay. It does not change the gas itself, the pipes, or who fixes a fault in the street — that is your distributor, and it stays the same regardless of retailer. There is no interruption to your supply; nobody visits, nothing is disconnected, and the gas keeps flowing the whole time.
Because the physical supply is untouched, switching is low-risk. The main things to get right are timing around any exit fees and making sure you are moving to a genuinely better plan rather than a shinier version of the same thing.
Before you switch
- Find a recent gas bill and note your annual usage in megajoules, your supply charge, and your current usage rates.
- Check your current plan for a discount benefit end date and any exit or early-termination fee — these are on the plan's basic price document.
- Compare available plans costed on your real usage, including how stepped rates apply, so the ranking reflects what you would actually pay.
- Confirm the new plan's rates, supply charge, discount conditions and contract length, and read the fee for leaving early if there is one.
- Check you are eligible and that any concession you receive can carry across.
Making the switch
- Sign up with the new retailer online or by phone — you generally do not need to contact your old retailer, as the new one handles the transfer.
- Provide your address and, if asked, your meter identifier (MIRN) from your bill.
- You get a cooling-off period, usually ten business days, during which you can cancel the switch without penalty.
- The transfer completes at your next meter read or an agreed date; you receive a final bill from your old retailer for gas used up to the changeover.
- Check your first new bill against the rates you were quoted to make sure they match.
Common traps to avoid
Watch the discount clock. Retailers often win you with a time-limited discount and then revert you to higher standing rates. Note the end date and plan to re-compare when it lapses rather than drifting onto the default rate.
Do not assume loyalty is rewarded — in energy it usually is not. The best rates are typically offered to new customers, so re-checking the market every year or so is normal and sensible.
Beware bundled offers that lock a poor gas rate to a good electricity rate. EnergySorted is independent and takes no retailer commissions, so its ranking is not tilted toward whoever pays it. It costs each plan on your usage, which is where bundle maths either holds up or falls apart.
