Do I need to switch energy supplier when moving house in the UK?

You don’t have to switch immediately. When you move in, your home will already be supplied by the current supplier. You can stay temporarily, but you can usually switch to a cheaper deal once you’ve opened an account and have your opening meter readings.

How do I tell my energy supplier I’m moving house?

Contact your supplier as soon as you have a move date. Provide your moving-out date, forwarding address, and final meter readings on the day you leave (or within 24 hours). This helps ensure your final bill is accurate and avoids being charged after you’ve moved out.

What meter readings do I need when moving out?

Take gas and electricity readings on moving day for your old property and the day you move in for your new property. Photograph the meters (showing the reading and serial number if possible) as proof in case there’s a dispute.

When should I take the opening meter readings at my new home?

Take opening readings as soon as you get access (ideally on the move-in day) before you use much energy. Share them with the current supplier to set up your account and ensure you’re not billed for the previous occupier’s usage.

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

If you don’t know the current supplier, check any welcome letters, labels on the meter, or ask the landlord/agent/seller. You can also use UK supplier lookup services for electricity and gas by providing your address and, where needed, your meter point details.

Can I switch energy supplier as soon as I move in?

In many cases, yes—once you’re responsible for the supply and have submitted your opening readings. If there’s an outstanding debt attached to the meter (not yours), or if account details haven’t been set up yet, you may need to resolve that first.

Will switching supplier affect my energy supply during the move?

No. Switching supplier doesn’t interrupt your gas or electricity supply. The same pipes and wires deliver your energy—only the billing supplier changes.

How long does an energy supplier switch take in the UK?

Switching typically completes within a few working days in the UK for many suppliers, though timings can vary. You’ll receive confirmation of the switch date, and your new supplier will handle the process.

What happens to my final bill when I move out?

Your supplier uses your final meter readings to calculate your closing balance. If you’ve overpaid, you should receive a refund; if you’ve underpaid, you’ll need to pay the remaining amount. Provide a forwarding address so the final bill reaches you.

How can I avoid being billed for the previous occupier’s energy use?

Submit opening meter readings immediately and keep photo evidence. Make sure your account start date matches your move-in date. If you receive bills addressed to ‘The Occupier’ for earlier periods, contact the supplier and confirm your tenancy/ownership start date.

Do I need to pay exit fees if I’m in a fixed energy tariff and move house?

It depends on your tariff terms. Some suppliers let you transfer your tariff to your new address, while others may charge an exit fee if you cancel early. Check your contract or ask your supplier if you can ‘move’ your tariff to avoid fees.

Should I transfer my current tariff to my new home or switch to a new deal?

If your current tariff is competitive, transferring can be convenient and may avoid exit fees. If prices have changed or your usage pattern will be different, comparing tariffs and switching could save money. A quick comparison can help you choose the best option for your new address.

Fast answer: do you switch when you move?

In the UK, you don’t need to switch supplier to keep your energy on when you move. Your new home will already be supplied by the current supplier (you simply become the new account holder). In most cases, the smoothest approach is:

1) Close your old account properly

Tell your old supplier your move-out date, give a final meter reading (photo helps), and provide a forwarding address for the final bill.

2) Open an account at your new address

On move-in day, take meter readings and contact the existing supplier for that property to set up your account.

3) Then compare tariffs and switch (if it suits you)

Once your new account is live and you’ve got the right meter details, you can switch supplier without losing supply.

Key takeaway: You can usually switch quickly after moving in, but you should still register with the current supplier first so bills and meter details start correctly. This reduces the risk of estimated readings, debt mix-ups, and delayed final bills.

If you’re a tenant

Check your tenancy agreement. You normally can choose your supplier, but some serviced or bills-included tenancies work differently.

If you have a prepayment meter

Top-up and key/card rules matter on move day. You may need to stay with the current supplier briefly while you’re registered.

If you have a smart meter

Not all smart functions stay “smart” with every supplier. We cover what that means and what to check before switching.

Moving house energy checklist (UK): what to do and when

Use this timeline to minimise incorrect bills, avoid debt being linked to you, and keep your options open to switch.

Before you move (ideally 2–3 weeks ahead)

Find your current tariff details: payment method (Direct Debit, cash/cheque, prepay), whether you’re fixed, and any exit fees or contract end date.
Decide whether to transfer or close: most suppliers treat a move as closing the old supply and opening a new one. Some let you keep the same supplier at the new address if they serve it.
Set a reminder for move-out day: meter readings, photos, and forwarding address.
If you’re in credit: expect it back after the final bill is produced (timings vary). Don’t cancel your Direct Debit too early if your supplier advises against it.

On move-out day

Take meter readings for gas and electricity as close to handing over keys as possible. Include meter serial numbers if you can.
Take clear photos of each meter reading and the meter itself (useful if there’s a dispute).
Tell your supplier: move-out date, readings, forwarding address, and preferred contact details.

On move-in day

Locate the meters (including any external cupboards) and take readings immediately.
Identify the current supplier for gas/electric (they may differ). If you don’t know:
- Electricity: check your Meter Point Administration Number (MPAN) on old paperwork, or ask the local network operator if needed.
- Gas: use the Meter Point Reference Number (MPRN) and the national gas supplier lookup service (see sources below).
Contact the current supplier to open your account (don’t worry—this doesn’t lock you in long-term).
Check meter type: credit meter vs prepayment; single-rate vs Economy 7; smart meter model.

After you’ve moved in (first 1–2 weeks)

Confirm your opening readings have been accepted (and are not “estimated”).
Check your payment method and set a realistic Direct Debit (avoid surprise debt building up).
Compare and switch when you’re ready—especially once your account is active and the property’s meter details are correct.

Important: you will not be “cut off” because you switch. Supply continues; only billing changes. If you have a prepayment meter, your top-up method can change after the switch completes.

Compare home energy for your new address

Get an estimated quote and switching options. We’ll use your details to help match tariffs to your meter type and payment preference.

Good to know: If you don’t yet know your meter type (smart, prepay, Economy 7), you can still start a comparison—just tell us what you do know and we’ll help narrow it down.

What happens after you submit?

We match your postcode and preferences to available domestic tariffs (where offered).
We highlight key terms (unit rates, standing charges, exit fees, payment method).
If you choose to proceed, the new supplier handles most of the switch admin.

Two realistic moving scenarios (with numbers)

These examples are illustrative to show how final bills and timing can play out. Actual rates and timings vary.

Scenario A: fixed tariff, leaving early

Assumptions: Dual fuel, paying by Direct Debit. Fixed tariff ends in 5 months. Exit fee: £50 per fuel (£100 total). Final month’s usage estimated at £120.
What happens: You give move-out readings on the day you leave. Supplier issues a final bill: usage £120 + exit fees £100 = £220 (minus any account credit).
Best move: If you can, check whether the tariff allows moving the contract to your new address. If not, compare whether paying exit fees is worth it versus staying until contract end (often not possible if you’ve moved).

Scenario B: move-in with prepayment meter

Assumptions: New home has a prepayment electricity meter. You top up £30 on day 1. Supplier registration takes 3–7 days. You then start a switch that completes in ~5 working days (typical, not guaranteed).
What happens: Your energy supply continues throughout. You may keep topping up with the existing supplier until the switch completes; any remaining credit is handled under the supplier’s process (rules vary by meter type and supplier).
Best move: Register first, keep receipts for top-ups, and only then switch—this helps ensure the opening balance and responsibility dates are correct.

Numbers shown are examples to help you plan cashflow (exit fees, overlap, top-ups). Always check your supplier’s tariff terms and your opening/closing readings.

Switching options when you move: what’s best?

There isn’t one right answer. This comparison helps you choose a low-hassle route while keeping costs and billing risk in check.

Option	When it suits	Pros	Watch-outs
Register, then switch	Most moves (tenants & homeowners)	Lowest billing risk; readings tie to the right account	You may be on a higher standard variable tariff briefly
Switch immediately (day 1)	If you already know meter details and supplier accepts switch	Potentially quicker onto a preferred tariff	Higher chance of reading disputes or delays if details are wrong
Stay with current supplier	Short stays, renovations, or admin simplicity	Least admin in the first few weeks	May not be best value; tariff may be variable
Take your supplier with you (if offered)	If your supplier supports “home move” and serves new address	May keep a fixed tariff and avoid exit fees	Not always available; meter/payment types can affect eligibility

Quick decision checklist: who it suits

Register then switch if you want fewer billing surprises.
Switch immediately if you have clear meter photos, serial numbers, and you’re confident about the meter type (e.g., Economy 7 vs single-rate).
Stay put temporarily if you’re mid-move, doing work, or the property details are uncertain.

Who it may not suit (or needs extra care)

Prepayment meters: switching is possible, but top-ups/credit handling can be fiddly—register first.
Complex meters: Economy 7, multi-register, or smart meters with comms issues—confirm details before you switch.
Fixed tariff with exit fees: check whether moving the contract is allowed; if not, budget for fees.

Reminder: Your energy supplier is different from your network operator. You can switch supplier, but your local electricity distribution network (DNO) stays the same.

Final bills, costs, exclusions and common pitfalls

Most moving-house energy issues come down to dates, meter readings, and who’s responsible for what period. These are the big ones to watch.

1) Estimated readings on the final bill

If you don’t provide readings, suppliers may estimate—sometimes high. Always submit readings and keep dated photos.

2) Exit fees (fixed tariffs)

Some fixed deals charge per fuel if you leave early. Check your tariff information and whether “home move” avoids the fee.

3) Cancelling Direct Debit too soon

If you cancel before the final bill, a supplier may mark the account unpaid. If you can, wait until the final balance is settled.

4) Previous occupant’s debt

You aren’t responsible for someone else’s energy debt. Opening readings and your move-in date help prove where your responsibility starts.

5) Economy 7 / multi-rate meters billed as single-rate

If your meter has day/night registers, make sure the supplier records the correct configuration—or your bills can be wrong.

6) Smart meter not communicating

A smart meter can act like a “dumb” meter if comms aren’t set up. You may need to provide manual readings until it updates.

If your final bill looks wrong: a simple challenge path

Check the dates billed match your move-out date.
Check the closing readings match what you submitted (or your photo evidence).
Ask for a rebill if readings or dates are wrong. Keep everything in writing if possible.
If unresolved, follow the supplier’s complaints process; you can escalate to the Energy Ombudsman (see sources).

What this guide doesn’t cover (so you’re not misled)

Business energy contracts and meters (EnergyPlus comparisons here are for domestic supply).
District heating / heat networks (billing and switching rights differ).
Off-grid fuels like LPG oil deliveries (separate market and contracts).
Complex landlord arrangements where energy is bundled into rent or managed supply is mandated.

FAQs: moving house energy supplier switch & final bills

Will I be without gas or electricity when I move in?

Usually no. The property already has a supplier. Your job is to set up an account with the existing supplier and provide opening readings. Switching later doesn’t interrupt supply.

How soon can I switch energy supplier after moving?

Many people switch within the first couple of weeks. Practically, it’s often best to register first, ensure your opening readings are correct, then start the switch. Timings vary by supplier and meter setup.

Do I need to tell my old supplier I’m moving?

Yes. Give your move-out date, final readings for each meter, and a forwarding address. Without this, your final bill may be estimated or sent to the old address.

How long does a final bill take in the UK?

It can vary depending on readings, account status and supplier processes. If you’ve provided readings and it’s still delayed, contact the supplier and ask when you’ll receive the final statement and any refund due.

What if I can’t find my meters or the meter serial numbers?

Start with the usual locations (cupboard under stairs, utility room, external meter box). If you still can’t find them, ask your landlord/letting agent or the property’s previous occupant if possible. For supplier identification, you can use national lookup routes (see sources below).

I’m moving into a home with a prepayment meter—can I switch?

Usually yes, but it’s often smoother to register with the current supplier first so your move-in date and opening position are correct. Keep top-up receipts. Some suppliers have extra checks for prepayment customers.

Can a landlord stop me switching supplier?

Often, tenants can choose their supplier. But there are exceptions (for example, if bills are included, or in some managed/serviced arrangements). Check your tenancy agreement and clarify with the agent/landlord if unsure.

What happens to my credit balance when I move out?

Any credit is typically refunded after your final bill is produced (or used to offset what you owe). Keep your Direct Debit active until your supplier confirms the account is closed and settled, unless they advise otherwise.

Do I need to give both gas and electricity readings?

Yes—if the property has both fuels. For Economy 7 or multi-rate electricity meters, provide all registers (e.g., day and night) and label them clearly.

How we assess moving-house switching (our approach)

We built this guide around the points that most often cause incorrect bills or delays when people move. We prioritise actions that reduce risk first (readings, dates, account responsibility), then look at switching choices.

Primary focus: correct billing periods, meter reading evidence, and safe switching order.
UK-specific factors considered: meter types (credit/prepay/smart, Economy 7), payment methods (Direct Debit vs prepay), fixed-term exit fees, supplier “home move” policies, and regional pricing differences.
Limitations: supplier processes and timings vary; some properties have unusual metering (multiple meters, communal supply, heat networks) that require bespoke advice.
Numbers shown: scenario figures are illustrative only and not a promise of cost or savings.
