How to Switch LPG Supplier in the UK

Why switch LPG supplier?

Switching supplier is usually about getting a better deal and avoiding paying more than you need at renewal.

Common reasons UK customers switch include:

• Lower LPG price per litre (especially at contract renewal)
• Fairer contract terms and fewer surprises
• Better delivery reliability and communication
• Clearer tank rental / standing charges and minimum order rules
• Improved customer service when issues arise

Before you start: what type of LPG supply do you have?

There are two main domestic LPG setups in the UK, and switching works slightly differently for each:

• Bulk LPG tank (propane) – a tank at your property, filled by a tanker. This is the most common setup for off-grid central heating and hot water.
• LPG cylinders – bottles for cooking, caravans, or patio heaters. This content focuses on bulk tank switching, because cylinders are normally a straightforward “buy where you like” arrangement.

How to switch LPG supplier (step-by-step)

1) Check your current contract and renewal date

Find out when your current agreement ends and whether there are any exit fees or notice periods. Many suppliers run fixed terms, so knowing your contract end date is key.

2) Confirm who owns the tank and what it costs

In most cases, the supplier owns the tank and you pay a tank rental / standing charge.
When you switch, the tank may be:

• Transferred to the new supplier, or
• Replaced (less common, but possible depending on the situation)

Your new supplier will normally handle the tank transfer process, but it’s helpful to know what you currently pay and what’s included.

3) Get comparable quotes (like-for-like)

Ask for a quote that clearly states:

• Price per litre (and whether it’s fixed or variable)
• Contract length
• Tank rental / standing charge
• Minimum order and any delivery charges
• Payment terms (direct debit, pay on delivery, credit options if offered)

The best quote isn’t always the lowest unit price—terms and service matter, especially in winter.

4) Choose a supplier and let them manage the switching process

Once you accept an offer, the new supplier will usually:

• Contact your existing supplier to initiate the switch
• Arrange the tank transfer (or replacement if required)
• Coordinate any safety checks / paperwork
• Set up your account, payment method, and delivery schedule

5) Plan your tank level so you don’t run low during the switch

Try to avoid switching when your tank is nearly empty. If you’re low, you may need a top-up first—your new supplier can advise on the cleanest way to handle this without delaying the switch.

6) Keep records and confirm your new rates in writing

Ask for confirmation of your agreed price, contract length, and any charges. File the documents so you can reference them at renewal time.

How long does it take to switch LPG supplier?

Switching timelines can vary depending on contract status, tank arrangements, and administrative steps.

The key is to start early—especially if you’re approaching winter—so you’re not forced into an expensive renewal.

Common mistakes to avoid when switching

• Waiting until the last minute at renewal, when options are more limited
• Comparing quotes without checking standing charges or minimum order rules
• Ignoring service factors like delivery lead times and communication
• Running the tank too low during the switch window
• Not getting the agreed price in writing

FAQs about switching LPG supplier

Can I switch LPG supplier if I’m in contract?

Sometimes—but it depends on your contract terms and whether exit fees apply. If you’re mid-contract, you may still be able to line up a switch for the end of your term or renegotiate.

Will I need a new LPG tank?

Not usually. Many switches are completed via a tank transfer process, handled between suppliers. In some cases, a tank change may be required, but the supplier will advise.

Is switching worth it for smaller users?

It can be. Even with lower annual usage, a better unit rate and fairer standing charge can reduce costs over a year—especially if your current renewal quote is high.
