Fast answer: what’s the cheapest fixed energy tariff for a new mover?
There isn’t one single “cheapest fixed tariff” for everyone in the UK. For new movers, the cheapest fix is the tariff that gives the lowest estimated annual cost for your new address, once you account for:
- Unit rates (p/kWh) for electricity and/or gas
- Standing charges (p/day), which vary by region
- Payment method (Direct Debit vs variable options; prepayment often differs)
- Meter type (single-rate, Economy 7, smart, prepay)
- Fees and terms (exit fees, minimum term, discounts, eligibility)
New mover reality check: when you move in, you’ll be put on the property’s current supplier (often on a standard variable tariff). You can usually switch soon after, but timing depends on meter details, opening readings and whether you’re in debt to the supplier.
Key takeaways (quick wins)
- 1) Get the right details first
- Take opening meter readings on move-in day and confirm whether you have gas, electricity, or both, plus meter type (e.g., Economy 7 or prepay).
- 2) Compare on total cost, not headline rates
- A lower unit rate can be offset by a higher standing charge (or vice versa). Always compare the estimated annual cost for your new postcode and usage.
- 3) Don’t lock in before you understand fees
- Fixed tariffs can include exit fees. If you might move again soon, consider shorter fixes or low/no exit fee options where available.

New mover checklist before you switch (the practical bits)
Comparing fixed tariffs: what “cheapest” looks like in practice
Fixed tariffs usually keep your unit rate and standing charge the same for the term (unless your contract allows changes). The best value for a new mover is the fix that fits your expected time in the home, meter type and risk tolerance.
| Option | Typical term | Why it can be “cheapest” | Watch-outs for new movers |
|---|---|---|---|
| Short fixed tariff | 6–12 months | Good if you want price certainty but may move again soon; can limit exposure if prices fall later. | May have exit fees; limited availability for some meter types. |
| Standard fixed tariff | 12–24 months | Often strongest value if you’ll stay put and want predictable bills. | Higher risk of paying exit fees if you leave early; check if fees are per fuel. |
| No/low exit fee fixed tariff | Varies | Can be “cheapest overall” if you’re unsure how long you’ll stay (less penalty risk). | Rates may be slightly higher; always compare total annual cost. |
| Standard variable tariff (SVT) | No fixed end date | Flexibility (no exit fees). Useful temporarily while you gather meter and usage info. | Prices can change (within Ofgem price cap rules). Often not the cheapest long-term. |
Decision checklist: who a fixed tariff suits
- You want predictable pricing for 12+ months
- You can pay by Direct Debit (often the widest availability)
- You’re happy to commit and understand exit fees
- Your meter type is supported (single-rate / Economy 7 / smart, depending on supplier)
Who it may not suit (or needs extra care)
- You expect to move again soon (check exit fees and contract length)
- You’re on/need a prepayment meter (fewer fixed options; terms differ)
- You’re unsure you’ll pass a credit check for certain tariffs
- You have complex usage (e.g., Economy 7 with high night use) and need tailored rates
Two realistic scenarios (with numbers)
These examples show how “cheapest” can change. Figures are illustrative estimates using simplified assumptions.
Scenario A: London flat, electricity-only
Assume 2,000 kWh/year, single-rate meter.
- Tariff 1: 27p/kWh + 60p/day standing charge → ~£910/year
- Tariff 2: 29p/kWh + 45p/day standing charge → ~£783/year
Why: Lower standing charge can outweigh a higher unit rate for lower usage homes.
Scenario B: Semi-detached in North West, dual fuel
Assume 3,100 kWh electricity + 12,000 kWh gas/year, Direct Debit.
- Fix 12 months with exit fees: estimated ~£1,615/year
- No-exit-fee fix: slightly higher rates → ~£1,670/year
Why: The cheaper annual estimate may be worth it only if you’re confident you’ll stay for the term.
Assumptions: costs approximated as (unit rate × usage) + (standing charge × 365). Real tariffs include VAT, billing options and may vary by region and eligibility.
Costs, exclusions and common new-mover pitfalls
1) Standing charges can dominate low usage homes
If you’re in a small flat or out of the house a lot, the standing charge can be a large part of your bill. Compare on annual cost and check your region.
2) Exit fees (often per fuel)
Some fixed tariffs charge an exit fee if you leave before the end date. On dual fuel, it may apply to gas and electricity separately. Always check the tariff details.
3) Economy 7 and multi-rate meters
Economy 7 works best if you can shift usage to night rates (e.g., storage heaters). A “cheap” single-rate fix can be costly if it removes your night rate benefit.
4) Prepayment meter limitations
Not all suppliers offer the same fixed deals on prepay. If you want to move from prepay to credit meter, you may need a meter change and eligibility checks.
5) Opening readings and back-billing disputes
If opening readings aren’t correct, you could be billed for the previous occupant’s energy. Take clear photos of meters (including serial numbers if possible) and submit readings promptly.
6) Tenants: permissions and responsibility
If you pay the energy bills, you can usually choose the supplier. If bills are included in rent or the landlord is the account holder, switching may not be possible without agreement.
Important: If you owe money to your current supplier, you may be blocked from switching (especially on prepayment), although there are routes to switch in some cases. If you’re struggling, see support from Citizens Advice energy guidance.
FAQs: cheapest fixed energy tariffs for new movers
Can I switch energy supplier as soon as I move in?
In most cases, yes—once you’ve registered as the bill payer with the current supplier and have your opening readings. Some switches can be delayed if details don’t match (e.g., wrong meter information) or if there are account issues to resolve.
How do I find out who supplies my new address?
Check any welcome letter left at the property, ask the letting agent/landlord, or look for supplier branding on the meter/in-home display. For electricity, you can also use industry lookup services (availability varies). If unsure, your previous occupant or landlord may know.
Will the “cheapest fixed tariff” be the same in every UK region?
No. Standing charges and unit rates can vary by region, and tariffs may be restricted by meter type and payment method. That’s why postcode-based comparisons are important.
Is a fixed tariff always cheaper than a standard variable tariff?
Not always. Fixed tariffs offer price certainty, but the best option depends on current market pricing, your usage, and whether the fix includes fees. Always compare the estimated annual cost and consider how long you expect to stay.
What if my new home has a prepayment meter?
You can still compare, but your tariff options may be more limited and priced differently. If you want to change to credit meter billing, you’ll typically need to pass checks and may need a meter exchange—ask the supplier about process and timescales.
Do I need my MPAN/MPRN to switch after moving?
It helps, but it’s not always required to start comparing. Many switches can proceed with your address and meter details. If there’s a mismatch, the supplier may request your MPAN (electricity) and MPRN (gas) later.
Can I switch if I’m renting?
Usually yes if you’re responsible for paying the bills. If energy is included in rent, or the landlord remains the account holder, switching may not be possible without the landlord’s agreement.
Could I be charged for the previous occupant’s energy?
You shouldn’t be, but incorrect opening readings can cause disputes. Take photos of the meter on move-in day and submit the opening readings promptly. Keep your tenancy agreement completion date as evidence.

How we assess “cheapest fixed tariff” for new movers
We treat “cheapest” as the lowest estimated annual cost for a like-for-like supply at a given address, not the lowest headline unit rate. Our comparisons focus on:
- Total estimated annual cost (unit rates × usage + standing charges × 365)
- Tariff structure (single-rate vs Economy 7/multi-rate; gas + electricity vs single fuel)
- Payment method (e.g., Direct Debit vs alternatives where available)
- Contract terms (term length, exit fees, eligibility constraints)
- New mover constraints (unknown usage, meter details confirmation, registration timing)
Limitations: Tariff availability can change daily and may depend on credit checks, meter compatibility and supplier acceptance. Regional prices vary, and your actual bill depends on real usage, VAT, and any changes allowed under the contract.
