Should I switch before I move or after I move?

Usually, switch after you move in: take responsibility for the existing supplier on the day you get the keys, submit opening readings, then compare and switch. If your current tariff has exit fees or you’re in a fixed contract, check your terms before switching early.

How do I avoid paying for the previous occupant’s energy use?

Take clear opening meter readings (and a photo) on move-in day and give them to the current supplier as soon as possible. Make sure the supplier has your full name, move-in date, and contact details so you’re billed only from the date you became responsible for the property.

Will I lose energy supply if I switch during a home move?

No. Your gas and electricity supply stays on during a supplier switch—only the company that bills you changes. The only exception is if there’s an unsafe meter or an emergency situation requiring disconnection, which is unrelated to switching supplier.

Can I switch if I’m renting and moving house?

In most rentals, yes—if you’re responsible for paying the energy bills, you can choose the supplier. If bills are included in your rent or the landlord manages the energy account, you may not be able to switch. Check your tenancy agreement first.

What details do I need to switch energy supplier when moving?

You’ll typically need your new address, move-in date, opening meter readings (or smart meter details), and payment details (e.g., Direct Debit). If available, your MPAN (electricity) and MPRN (gas) can help speed things up, but they’re not always required.

What if the property has a prepayment meter?

You can still switch, but you may need to register with the current supplier first and ensure the meter is correctly set up in your name. If you want to move to a credit meter, you can request a meter exchange (eligibility checks may apply).

Can I keep my current supplier when I move house?

Sometimes. If your current supplier serves your new address, you may be able to move your account or open a new account with them at the new property. If they can’t supply the new address, you’ll need to use the existing supplier initially and then switch.

Can I switch energy supplier while moving house in the UK?

Q: Can I switch energy supplier while moving house in the UK?

Yes. You can switch energy supplier when you move home, but in most cases it’s simplest to first take over the current supplier at your new address, provide opening meter readings, and then start a switch once your account is set up. This helps avoid billing issues and ensures you’re not left without an active account for the property.

Q: How long does an energy switch take in the UK?

Many switches complete within around 5 working days, though timings can vary depending on the supplier and any issues with account details or meter information. You’ll be told your expected switch date when you apply.

Yes—often it’s the best time to review your tariff. This guide explains your options (switch now, switch later, or keep the current supplier), how long it takes, what to do with meter readings, and how to avoid common move-day billing problems.

Estimates only. Availability, tariffs and timings vary by supplier, meter type and eligibility checks. Always keep copies of opening/closing meter readings.

Fast answer: you can switch—just time it right

In most UK moves, you can switch energy supplier. The practical choice is whether you switch for your new address straight away or wait until your first bill is set up. The key rule: you’re responsible for the energy you use from the day you move in, and you’ll usually start on the property’s existing supplier (often on a standard variable tariff) until a switch completes.

Best default approach

Take opening meter readings, tell the current supplier, then compare and switch within the first 1–14 days (or earlier if you have a completion date).

When to be cautious

If you’re on a fixed deal with exit fees, have a prepayment meter, or there’s a debt flag at the new property, switching may be delayed or cost more.

Timings (typical)

A supplier switch commonly completes in around 5 working days once initiated, but meter/data issues can extend this.

Key takeaway: You don’t have to stay with the old supplier at your new home. But don’t ignore them—notify them of your move and provide accurate readings so you don’t inherit someone else’s usage.

Compare options for your new address (whole of market)

If you’ve got a completion/move-in date, you can usually start a switch close to that date so your new tariff begins soon after you arrive. If you’re not sure of dates yet, you can still compare now and decide when you’re ready.

What you’ll need: new postcode, whether you pay by direct debit or prepayment, and (if you know it) your meter type (smart / traditional / prepay). Don’t worry if you don’t have the MPAN/MPRN yet—many switches can still be quoted from the postcode.

Move-day steps (simple and reliable)

Before you move (optional): Ask your solicitor/landlord for the current supplier and whether the property has a smart meter or prepayment meter. If you’re renting, check your tenancy agreement for any supplier restrictions (it’s rare, but it happens).
On moving day: Take clear photos of gas and electricity meter readings (including the meter serial number if visible). Note the time and date.
Within 24–48 hours: Contact the existing supplier(s) for the new property to set up your account and provide opening readings. This reduces estimated bills.
Then compare: Choose your preferred supplier/tariff and start the switch. Keep an eye out for any emails asking you to confirm details.
When the switch completes: Provide/confirm final readings to the old supplier (your previous home) and opening readings to the new supplier (your new home). Keep all confirmations.

Two realistic examples (with assumptions)

Scenario A: Switch soon after moving in

A couple move into a 2-bed flat and spend 3 weeks on the existing supplier’s standard variable tariff while they switch.

Assumptions: Typical usage during 21 days: 180 kWh electricity and 350 kWh gas (varies widely by season/home).; SVT unit rates: electricity 26p/kWh, gas 7p/kWh; standing charges electricity 60p/day, gas 32p/day.; New fixed deal is ~10% cheaper on unit rates; standing charges similar.
Estimated impact: Staying on SVT for 21 days costs about £85 (usage) + £19.74 (standing) ˜ £105. Switching 2 weeks earlier might reduce the usage portion by ~10% (around £8–£9 on this example). Not huge, but worthwhile—especially over months.

This is an illustration only. Your rates and consumption may be very different; winter gas use can be much higher.

Scenario B: Exit fees vs moving timing

A household is on a fixed tariff at their current home with £50 exit fee per fuel and moves in 30 days.

Assumptions: Exit fees: electricity £50 + gas £50 = £100 (check your tariff terms).; Potential saving at new home by switching immediately after move: £18/month estimated vs staying longer on SVT.
Estimated decision: If you would only gain ~£18/month, paying £100 to exit early may take ~5–6 months to break even. In that case, you might choose to avoid exit fees (if your supplier lets you move the tariff, or if you’re close to the end date) and focus on switching at the new property as soon as practical.

Some suppliers waive exit fees in certain move situations or if you’re within a set window of the tariff end date—always confirm directly.

Quick decision checklist (who it suits)

Switching now suits you if:

You’ll be at the property for 6+ months.
You’re likely to land on an expensive SVT initially.
You can provide accurate readings on move-in.
You want direct debit billing (often required for the cheapest deals).

Switching may not be urgent if:

You’ll move again very soon.
You’re dealing with renovation/void periods (usage is low).
You need to resolve a prepayment or debt issue first.
You don’t yet have keys/access to take readings.

Your switching options when moving (UK comparison)

There are three common routes. The “best” one depends on your tariff, meter setup and how confident you are about move dates.

Option	What happens	Pros	Watch-outs
1) Switch after you move in	You open an account with the existing supplier first (using opening readings), then initiate a switch.	Lowest admin risk; readings are clearer; easiest if dates change.	You may spend a short time on a standard variable tariff.
2) Arrange a switch close to completion	You start the switch using the new address details so it completes soon after you move in.	Minimises time on SVT; good if you’re organised and dates are firm.	If completion changes, you might need to amend dates; access to opening readings still matters.
3) Keep the current supplier longer	You remain with the property’s existing supplier beyond the first bill (or keep your old supplier if they can take over the new address).	Simpler if you’re dealing with repairs, paperwork, or meter issues.	May cost more over time; you could miss better tariffs or direct debit discounts.

Switching checklist (do this to avoid billing disputes)

Take photos of gas and electricity meters on move-in (and move-out at your old home).
Record meter serial numbers if shown (useful if there’s a mismatch).
Tell the supplier(s) for the new property your move-in date and opening readings.
If the home is all-electric (no gas), confirm this—don’t assume.
Keep emails/letters confirming account setup and switch start date.

What can affect eligibility or timing

Payment method: some tariffs are direct debit only.
Meter type: prepayment and some smart setups can limit tariff choice.
Address/meter data: incorrect MPAN/MPRN records can delay switches.
Debt flags: if the meter is linked to debt, it can complicate a switch (you shouldn’t be liable for a previous occupier’s debt, but it may still need resolving).
Region: standing charges vary by distribution region; quotes should reflect your postcode.

Costs, exclusions and common pitfalls (moving home)

Switching supplier is usually free, but moving home introduces a few UK-specific trip hazards. These are the ones that most often lead to incorrect bills or delays.

Exit fees on fixed tariffs

If you’re leaving a fixed-term deal at your old home, you may pay an exit fee per fuel. Some suppliers waive fees in certain situations, but you must check your tariff terms.

Estimated readings and “catch-up” bills

If you don’t provide opening readings, suppliers may estimate. If the estimate is wrong, you could get a larger “catch-up” bill later. Photos help resolve disputes quickly.

Prepayment meters

Some homes have prepay meters even if you plan to pay by direct debit. You can often request a change, but it may require checks and can take time. Tariff choice may be narrower.

Smart meter complications

Smart meters usually don’t stop you switching, but readings/comms can fail or the meter may operate in “dumb” mode temporarily. Always keep manual readings as a backup.

Supplier “deemed contract” at the new home

When you move in, you’re usually placed on a deemed tariff with the existing supplier. You can switch away, but you still need to register and pay for energy used before the switch completes.

Wrong supplier / wrong meter point

Occasionally, address records are incorrect (e.g., flats). If bills don’t match your meter serial number, query it early—this can delay switching until corrected.

Important: You should not be charged for a previous occupier’s energy use. If your opening reading is disputed, provide your move-in meter photos and move-in date, and ask the supplier to correct the opening read.

FAQs: switching energy supplier while moving

Do I have to use the existing supplier when I move in?

You’ll usually start with the existing supplier by default (a deemed contract) because they’re already supplying the property. You can switch to a new supplier once you’ve moved in (or sometimes arrange it close to completion).

Can I switch supplier before I move in?

Sometimes, yes—if you have a confirmed completion date and enough address/meter details. However, it’s often simpler to switch just after moving in so your opening readings and dates are correct.

How long does an energy switch take in the UK?

Many switches complete in around 5 working days, but it can take longer if there are meter data issues, smart/prepay complications, or mismatched address records (common with flats/new builds).

Will I have to pay an exit fee when I move?

Possibly. Exit fees typically apply if you leave a fixed-term tariff early at your old address. Some suppliers waive them in certain circumstances or near the tariff end date, but it’s tariff-specific—check your contract or supplier account.

What readings do I need when moving house?

Take closing readings at your old home and opening readings at your new home (gas and electricity), ideally with time-stamped photos. Provide these to the relevant supplier(s) to reduce estimated bills and disputes.

I’m renting—can my landlord stop me switching?

In most cases, tenants can choose their supplier if they pay the bills. Some tenancy agreements may have conditions (for example, not leaving debt or returning prepayment keys), so check your paperwork and keep records.

What if the new home has a prepayment meter but I want direct debit?

You can ask the supplier to move you to a credit meter (or smart prepay to credit, where available). Approval can depend on checks and the meter setup. While you’re on prepay, your tariff choices may be more limited.

What if I can’t find out who supplies the new property?

For electricity, you can use the UK’s "Find my supplier" approach via your network operator routes; for gas, the MPRN and supplier can usually be found via the national database services. If you’re unsure, we can still start with a postcode-based comparison and then confirm details once you’re in.

How we assess switching while moving (our methodology)

We wrote this guide to reflect what typically happens in UK home moves under current switching processes and common supplier practices. We focus on actions that reduce billing errors and make it easier to switch successfully.

Assumptions: users are domestic customers in Great Britain (not business accounts). Timings referenced are typical and can vary.
What we prioritise: accurate meter reads, clear responsibility dates, and identifying factors that affect tariff availability (direct debit, prepay, meter type, region).
Numbers used in scenarios: illustrative consumption and unit rates to show decision logic (not a promise of savings). Your actual rates depend on region and the tariff you’re offered.
Limitations: supplier rules change; some meters (especially prepayment) and address data issues can delay or restrict switching. We recommend confirming details with the supplier where needed.
