Fast answer: the cheapest tariff after moving home
In the UK, when you move in you usually start on the property’s existing supplier and a default tariff (often the supplier’s standard variable tariff). The cheapest option for your new home is typically found by comparing tariffs for your postcode, meter type and payment method, then switching once you’ve taken opening readings and ensured the account is in your name.
Key caveat: You can’t reliably pick “the cheapest tariff” without knowing your meter setup (credit vs prepay, smart meter mode, Economy 7/10, or half-hourly) and your expected usage. This guide shows what to check and how to compare properly.
Key takeaways
- Don’t cancel the existing supplier on moving day—take readings first.
- Confirm whether you’re credit or prepayment, and whether you have single-rate or Economy 7.
- Compare based on unit rates, standing charges, exit fees and tariff length—not headline savings.
- Switching is usually easiest once the supplier has set up your account (often within days), but you can start the process sooner once details are clear.
What to gather (5 minutes)
- Postcode + move-in date
- Opening meter readings (gas + electricity)
- Meter type: smart? Economy 7? prepay?
- How you want to pay: Direct Debit / on receipt of bill / prepay
Common “new home” pricing traps
- Comparing a single-rate tariff against Economy 7 without checking your actual usage split
- Missing prepayment limitations and debt screens
- Ignoring standing charges (can dominate low-usage homes)
- Switching before you’ve recorded readings (billing disputes)

Tip for movers: If you don’t have a bill yet, use your best estimate for occupancy and heating type. You can refine later—prices are still driven by your region, meter and payment method.
How to get the cheapest tariff after moving (step-by-step)
- Identify the current supplier (ask the agent/landlord, check any welcome letter, or call the Meter Point Administration Service for electricity and your gas transporter/supplier lookup where appropriate).
- Take opening readings on move-in day (photo helps). If it’s a smart meter, note the displayed readings as well.
- Contact the existing supplier to open the account in your name and provide readings. This reduces the risk of being chased for the previous occupier’s bill.
- Check your meter setup: single-rate vs Economy 7, credit vs prepay, smart meter mode, and whether you have a single or multi-rate meter.
- Compare like-for-like tariffs using your estimated annual kWh (or typical figures for your home size) and your preferred payment method (often Direct Debit is cheapest, but not always).
- Review exit fees and contract length. If you may move again soon, a no-exit-fee option can reduce risk.
- Start the switch once your account is set up (or sooner if the new supplier can proceed). Keep your opening readings and any confirmation emails.
- Check the first bill matches your opening reading and agreed tariff details. Query issues early.

Moving into rented accommodation? You can usually switch supplier if you pay the bills, but check your tenancy agreement and ensure any communal/heat network arrangements don’t apply.
Which tariff type is usually cheapest after moving?
“Cheapest” depends on your usage pattern and risk tolerance. For many movers, the decision is less about finding a magic tariff and more about choosing the right structure (fixed vs variable, single-rate vs multi-rate, credit vs prepay) and a competitive price for your region.
| Tariff option | When it can be cheapest | Watch-outs after moving | Best for |
|---|---|---|---|
| Fixed rate (12–24 months) | If the fixed unit rates + standing charges are competitive for your region and you want bill stability. | Check exit fees and whether the tariff is for your meter type (single-rate/E7/prepay). | Households staying put; budgeting-focused. |
| Standard variable tariff (SVT) | Rarely the cheapest long-term, but useful as a short-term default while you get set up. | Rates can change; you may overpay if you stay on it. Don’t assume it’s “capped” at the lowest price. | Short gap between move-in and switching; people avoiding exit fees. |
| No exit fee (fixed or variable) | If you want flexibility (possible re-move) and still want a competitive price. | Compare total estimated annual cost—rates can be higher to compensate for flexibility. | Renters, uncertain timelines. |
| Economy 7 / multi-rate | If you genuinely use a meaningful share of electricity overnight (storage heaters, charging, hot water). | Day rate can be higher. If your usage isn’t night-heavy, you can pay more than single-rate. | Homes with storage heating; off-peak users. |
| Prepayment tariff | If you must use prepay (meter installed) or prefer pay-as-you-go budgeting. | Switching can be restricted if there’s debt on the meter. Top-up methods vary by supplier. | Pay-as-you-go households; some rentals. |
Decision checklist: likely cheapest if…
- You can pay by monthly Direct Debit (often priced lower than pay-on-receipt).
- You have (or can use) a credit meter rather than prepay.
- Your tariff matches your meter rate structure (single-rate vs Economy 7).
- You compare the total estimated annual cost (unit rates + standing charges), not a single headline figure.
Who it suits / who it doesn’t
- Best suited to switching quickly
- New homeowners, long-term tenants, anyone facing higher-than-expected SVT charges.
- May need extra checks first
- Properties with prepayment meters, Economy 7/storage heating, heat networks, or unclear responsibility for bills.
Costs, exclusions and common pitfalls after moving
These are the issues that most often stop people getting the best price (or cause bill shocks) in the first month at a new address.
1) Standing charges add up quickly
If you’re a low-usage household (e.g. small flat, rarely home), the standing charge can form a large share of your bill. Two tariffs with similar unit rates can have very different standing charges depending on region and meter type.
2) Economy 7: cheap nights, expensive days
Economy 7 can be cheaper only if enough usage shifts to the off-peak period. If you don’t have storage heaters or you’re out all day and use electricity evenings, a single-rate tariff may cost less.
3) Exit fees and moving again
Some fixed tariffs have exit fees. If you might move within the contract term, consider no-exit-fee deals or shorter terms. Terms vary by supplier and product.
4) Prepayment meters: debt checks and top-up rules
If the property has a prepayment meter, switching can be more complicated. Some switches require the meter to be debt-free or for debt to be handled via an agreed process. If you inherit a meter with a balance or debt, contact the existing supplier promptly.
Important: You shouldn’t be billed for a previous occupier’s energy. Keep your move-in date, tenancy completion date and opening readings as evidence if there’s a dispute.
5) Heat networks & included bills
Some flats use communal heating/heat networks or have bills included in rent/service charges. In these cases, you may not be able to switch in the usual way for heating/hot water (but you might still control your electricity supplier).
Two realistic scenarios (with estimated numbers)
These examples show how “cheapest” changes with usage and meter type. Figures are illustrative estimates to help decision-making, not a prediction of your bill.
Scenario A: 2-bed house (gas + electricity), credit meter, Direct Debit
- Assumed usage: 2,900 kWh electricity/year; 12,000 kWh gas/year
- Tariff 1 (SVT-like): higher unit rates; standing charges similar
- Tariff 2 (competitive 12m fix): slightly lower unit rates; small/medium exit fee possible
| Item | Tariff 1 | Tariff 2 |
|---|---|---|
| Estimated annual electricity cost | £970 | £890 |
| Estimated annual gas cost | £960 | £890 |
| Estimated total annual cost | £1,930 | £1,780 |
Assumptions: example UK-style usage; includes standing charges; excludes cashback/discounts; prices vary by region and supplier.
Scenario B: 1-bed flat, electricity only, Economy 7 meter
- Assumed usage: 2,100 kWh electricity/year
- Off-peak split (example): 35% night / 65% day (typical varies widely)
- Compare: Economy 7 tariff vs single-rate tariff
| Item | Economy 7 | Single-rate |
|---|---|---|
| Estimated annual electricity cost | £820 | £790 |
| What this shows | Not always cheaper unless night use is high enough. | Often competitive for typical “daytime” flats. |
Assumptions: illustrative unit rates and standing charges; results can reverse if your night-time usage share is higher (e.g. storage heating or EV charging).
FAQs: cheapest energy tariff after moving home
Do I automatically join the previous occupier’s tariff?
You usually start with the property’s existing supplier, but not necessarily the previous occupier’s fixed deal. In many cases you’ll be placed on the supplier’s default tariff until you choose a new one.
Can I switch energy supplier as soon as I move in?
Often yes, but it’s safest to first take opening readings and ensure the account is set up in your name. If details are unclear (meter type, MPAN/MPRN, prepay status), get those confirmed to avoid delays.
What if I can’t find out who supplies my new home?
You can use the UK electricity supply number lookup (MPAS) and gas supplier lookups depending on network/area. If you’re stuck, your letting agent/landlord or the previous occupier may have paperwork. Keep using energy—don’t risk disconnection—but start enquiries straight away.
Is Direct Debit always the cheapest way to pay?
Not always, but it’s often priced lower than paying on receipt of bill. The “cheapest tariff” for you depends on the supplier’s pricing for your region and meter, plus your ability to pass any credit checks for certain products.
What if the property has a prepayment meter?
You can still compare, but your options may be narrower. If there’s debt on the meter, suppliers may require it to be handled before switching. Contact the current supplier with proof of move-in and ask how they’ll treat any previous occupier’s debt.
Do I need to give meter readings if I have a smart meter?
It’s still wise to record the opening readings (and take photos) on move-in day. Smart meters can lose connectivity or be in “dumb” mode, and having your own record helps resolve disputes.
Can my landlord stop me switching?
If you’re responsible for paying the energy bills, you can usually choose your supplier. However, some buildings have communal heating or arrangements where you don’t have a standard individual supply for heating. Always check your tenancy agreement and any building rules.
Will switching leave me without gas or electricity?
No—switching suppliers shouldn’t interrupt your supply in normal circumstances. Your meter and physical supply lines stay the same; only the billing supplier changes.

How we assess “cheapest” for movers
We treat “cheapest tariff after moving” as the tariff with the lowest estimated annual cost for a given household profile, while still being suitable for the home’s meter setup and the customer’s payment method.
- Inputs that change the result: postcode/region, meter type (single-rate, Economy 7, smart/prepay), payment method, expected annual usage (kWh), and eligibility criteria.
- Cost components we compare: unit rates, standing charges, contract length, exit fees, and any tariff restrictions (e.g. prepay compatibility).
- Why we use estimates: energy use varies widely by household size, heating system, insulation and behaviour. Supplier prices also change and may be withdrawn.
Limitations: This guide doesn’t guarantee the lowest price for every customer. Availability can differ by supplier, credit checks, smart meter configuration (including half-hourly settlement), and whether your property is on a heat network or has unusual metering.
