Fast answer: how to get the cheapest fixed energy tariff for house share UK
The cheapest fixed energy tariff for house share UK is the deal with the lowest estimated annual cost for your postcode once you include standing charges, unit rates, contract length and any exit fees. Because house-share usage patterns vary, the only reliable way is to compare fixed tariffs for your exact meter and payment method and check the full cost breakdown.
Key takeaway #1
“Cheapest” for sharers usually means lowest total bill, not the lowest unit rate. Standing charges can dominate if you’re often away.
Key takeaway #2
Make sure the tariff matches your setup: single vs Economy 7, smart meter, and credit vs prepay pricing can differ.
Key takeaway #3
If one housemate is the account holder, agree how bills are split and what happens if someone moves out mid-contract.
Quick caveat: We can’t show live “cheapest” deals on this page because prices change daily and vary by region and meter. Use the quote form to see current fixed tariffs for your postcode.
Find the cheapest fix for a house share (step-by-step)
Use this process to avoid the most common “cheap fix” traps in shared homes (like paying more overall due to standing charges or picking the wrong meter type).
- Confirm who can switch. Usually the named account holder (or landlord if bills are included) must approve changes.
- Check your meter type. Single-rate, Economy 7/10, smart meter and prepayment meters can have different prices and eligibility.
- Choose a “fix length” that matches your tenancy. If people may move out, a longer fix can be risky if there are exit fees.
- Compare on total annual cost. Look at the estimated annual cost for your usage, not just the headline unit rate.
- Read the key terms. Check exit fees, how the fix ends (rollover), and whether prices differ by payment method (Direct Debit vs cash/cheque).
- Set up simple bill splitting. Agree how you’ll handle variable usage (work-from-home, electric heating) and late payments.
Tip for house shares: if your household has irregular occupancy (weekends away, travel, term-time living), standing charges can matter more than you think. Compare with a realistic usage estimate and re-check if your household changes.
Two realistic house-share scenarios (with numbers)
Scenario A: 3 sharers, often out
Assumptions: 3-bed terrace, gas + electricity, mostly at work, average insulation, single-rate meter, paying by Direct Debit.
Example usage to compare: ~9,000 kWh gas/year and ~2,400 kWh electricity/year (typical-ish for a small shared home, but your home may be higher/lower).
What often makes the “cheapest fixed” here: a deal with competitive standing charges as well as rates, because low daytime use can make fixed standing costs a bigger slice of the bill.
Scenario B: 4 sharers, high electric use
Assumptions: 4-person flat, heavy appliance use, some work-from-home, electric cooking, possible electric showers, single-rate electricity.
Example usage to compare: ~4,200–5,000 kWh electricity/year (and gas may be low or not present).
What often makes the “cheapest fixed” here: a strong unit rate matters more than standing charge, because consumption is higher and shared across more people.
These scenarios are illustrative and do not reflect live tariff prices. You’ll see exact costs after entering your postcode and meter details.

Compare fixed-tariff choices for house shares
A “cheap” fixed tariff depends on your situation. Use the comparison below to choose what to prioritise before you run a live quote.
| Option | Best for | Watch-outs | What to check in quotes |
|---|---|---|---|
| 12-month fixed | Most house shares with a typical tenancy cycle | May include exit fees if you leave early | Exit fees, end-of-fix process, estimated annual cost |
| Longer fixed (18–24 months) | Stability if the household is likely to stay put | Harder if people move out; potentially more time “locked in” | Total cost over time, exit fees, how moving home is handled |
| Short fixed (under 12 months) | Uncertain tenancy dates or temporary house shares | May be less available; price can be higher than longer fixes | Availability for your meter type; any fees; renewal options |
| Fixed with a higher standing charge | High-usage shares where unit rate dominates | Can be expensive in low-usage months or if the home is empty | Standing charge, unit rate, your realistic usage estimate |
Decision checklist (who a fixed tariff suits)
A fixed tariff is often a good fit if…
- You want predictable pricing for budgeting in a shared home
- Your household will likely stay for the full term
- You can agree a simple, fair bill-splitting method
- You’ve checked any exit fees and can tolerate them if plans change
A fixed tariff may not suit if…
- You expect housemates to change frequently
- You’re unsure who has permission to switch (landlord/bills included)
- You’re on prepay and need maximum flexibility (options vary)
- Your home has Economy 7 and you haven’t checked day/night usage
House-share reality check: the “cheapest fixed tariff” for one group of sharers may be poor value for another—even at the same address—if occupancy and usage shift (e.g. one person starts working from home, or the property switches to electric heating).
Costs, exclusions and common house-share pitfalls
These are the reasons a “cheap” fix can become expensive in a shared home. Use them as a pre-switch checklist.
1) Standing charges
You pay these daily even if you use no energy. In low-usage house shares (people away, term-time living), standing charges can be a big share of the total cost.
2) Exit fees and tenancy changes
Some fixes charge a fee if you leave before the end date. If housemates rotate, decide who is responsible if the account holder moves out.
3) Wrong meter assumptions
Economy 7 (two-rate) tariffs can be good value only if enough usage happens at night. If you’re mostly daytime users, a single-rate fix may be cheaper overall.
4) Payment method differences
Tariffs can price differently for Direct Debit vs other methods. If the household needs to pay another way, compare like-for-like.
5) Credit checks & deposits
Some suppliers may run checks or request a deposit depending on circumstances. That can affect which “cheapest fixed” is actually accessible to your household.
6) Bills included in rent
If your landlord includes energy, you usually won’t be able to switch. If you’re unsure, check the tenancy agreement before starting.
What you can do today to reduce friction
- Take meter readings (and photos) on move-in day and on switch day.
- Pick one account holder and document the split in writing (even a shared note).
- Set a review date (e.g. 30 days before the fix ends) so you don’t drift onto a more expensive variable rate.
If you’re struggling with bills, independent help is available from Citizens Advice and Ofgem (see sources below).
FAQs: cheapest fixed energy tariff for house share UK
Can tenants in a house share switch to a fixed tariff?
Usually yes if you pay the energy supplier directly and you’re the named account holder (or have their permission). If bills are included in rent, you normally can’t switch because you’re not the bill payer. Always check your tenancy agreement and speak to the account holder first.
What does “cheapest fixed” actually mean for a shared home?
It means the lowest estimated annual cost for your household once you include unit rates, standing charges and any fees, based on your postcode, meter type and payment method. In house shares, the cheapest option can change if occupancy or working-from-home patterns change.
Will a fixed tariff always be cheaper than a variable tariff?
No. A fixed tariff offers price certainty for the unit rate (and sometimes standing charge), but it can be higher or lower than a variable tariff depending on market conditions and the specific deal. Compare based on total estimated cost and consider exit fees if you might want to change again soon.
How do we split bills fairly on a fixed tariff in a house share?
Most groups split the monthly Direct Debit equally, then review if someone uses significantly more (for example, electric heating in one room or working from home full-time). If you want more accuracy, agree on a simple rule (e.g. equal split plus a top-up for high users) and keep photos of meter readings to handle move-in/move-out dates.
What happens to a fixed tariff if a housemate moves out?
The tariff stays with the energy account, not the individual housemate. If the named account holder leaves, you may be able to change the name on the account, but you should check with the supplier first. If the home itself is changing occupiers, take final readings and settle up to avoid disputes.
Can we get a fixed tariff with a prepayment meter in a house share?
Sometimes, but availability varies by supplier and meter setup. Prepayment customers may see a different range of tariffs than credit meters. If you’re on prepay and want a fixed tariff, compare using your postcode and select the correct payment/meter type during the quote journey.
Do we need a smart meter to access the cheapest fixed deals?
Not always. Many fixed tariffs are available without a smart meter, but some deals and billing features may require one. If you have a smart meter, it can make readings easier in a house share, but you should still compare based on total cost and terms.
How long does switching take for a house share in the UK?
Switching is usually completed within days, but timelines can vary due to meter types, data matching and any issues on the existing account. You won’t lose supply during a normal switch. Take meter readings on the day you switch to help ensure the final and first bills are accurate.

How we assess “cheapest” for house shares
- Total estimated annual cost is the primary measure (unit rates + standing charges, based on your inputs).
- We highlight fit factors that commonly affect sharers: contract length, exit fees, meter type, and payment method.
- We avoid naming specific tariffs or rates on this page because prices change frequently and differ by region and eligibility.
Limitations and assumptions (read this if you want accuracy)
- Estimates depend on the usage figure you compare with. A house share can swing from low to high usage if occupancy changes.
- Tariff availability can vary by postcode region, payment method, meter type, and supplier checks.
- Some households have split responsibilities (e.g. landlord controls one fuel). That can limit switching options.
