Fast answer: what is the cheapest fixed energy tariff for shared houses UK?
The cheapest fixed energy tariff for shared houses UK is the live fixed deal with the lowest estimated annual cost for your exact postcode, meter type and payment method — and the right contract terms for your household.
Because shared houses often use more energy and have more occupants, the “cheapest” option isn’t just the lowest unit rate: exit fees, contract length, standing charges, and how you split bills can change what you actually pay.
Key takeaways for house shares
- Check who holds the account (the “bill payer”) — they’re responsible for switching and any debt/credit.
- Fixed deals can add stability, but may include exit fees if someone moves out mid-contract.
- Meter type matters: smart, traditional credit and prepayment meters can see different options and costs.
- Payment method can change prices (e.g. monthly Direct Debit vs receipt of bill).
- For HMOs, confirm whether bills are included in rent and whether the landlord must approve changes.
Quick “before you switch” checks
- 1) Are you allowed to switch?
- If you’re a tenant, check your tenancy agreement and confirm with the account holder/landlord where relevant.
- 2) Are you in a fixed term already?
- If you’re currently fixed, leaving early may trigger exit fees (check your latest bill or online account).
- 3) Do you know your usage?
- Use recent bills or smart meter data to avoid choosing a deal based on unrealistic estimates.
How to get the cheapest fixed deal for a shared house
In a shared house, you’re typically balancing price certainty with flexibility. Use this process to find a fixed tariff that’s genuinely cheapest for your situation — not just the lowest headline rate.
- Gather the essentials: postcode, current supplier name (from a bill), and whether you have a smart meter and/or prepayment meter.
- Use real usage if you can: total kWh over the last 12 months for electricity (and gas if you have it). If not, your comparison will use estimates.
- Decide your “move-out risk”: if housemates change often, shorter fixes (or low/no exit fee options if available) may suit better.
- Compare like-for-like: same payment method, same contract length, and check whether the tariff is dual fuel (gas + electricity) or electricity-only.
- Read the terms: especially exit fees, how prices are billed, and whether there are conditions (e.g. smart meter required).
Shared house tip: If you split bills, the “cheapest” tariff is often the one with predictable monthly costs and manageable exit fees. A deal that’s slightly higher but avoids large early-exit charges can reduce disputes when someone moves out.

Two realistic shared-house cost scenarios (with assumptions)
These examples show how contract terms can matter as much as headline prices. They are illustrative only — we do not use live tariff rates on this page. Your actual costs depend on your supplier, tariff, region, meter type, and usage.
Scenario A: 4-person gas + electricity share, one person moves out
- Assumptions: 4 tenants, monthly Direct Debit, fixed contract includes an exit fee, split evenly.
- What can go wrong: if the named account holder switches everyone onto a longer fix and a housemate leaves early, you may need to agree who covers any exit fee (or keep paying until term ends).
- Simple number example: if an early-exit charge of £150 applied and you split 4 ways, that’s £37.50 each — which can wipe out small monthly savings.
Scenario B: 6-person electricity-heavy share (no gas), high standing charge impact
- Assumptions: 6 occupants, electricity-only (e.g. immersion/heat pump/portable heaters), single electricity meter.
- What matters: where usage is high, a low unit rate can matter more; where usage is low (or people are away), standing charges can dominate.
- Simple number example: if standing charges total £300/year for the household, that’s £50 each per year before any energy use is counted.
Tip for smoother bill splitting: agree in writing (even a shared note) how you’ll handle exit fees, move-out dates, and meter reads at tenancy changes.
Comparing fixed tariffs for shared houses: what to look at
When you compare fixed energy deals for a shared house, focus on the parts that change your total bill and your risk if your household changes.
| What you’re comparing | Why it matters in a house share | What to check | Good fit if… |
|---|---|---|---|
| Estimated annual cost | Best single headline for “cheapest”, but only if usage assumptions are realistic. | Does it use your last 12 months’ kWh (preferred) or an estimate? | You have bills or smart data and stable occupancy. |
| Contract length | Longer fixes can increase move-out friction; shorter fixes can mean more frequent re-checks. | How many months? Any renewal rules? What happens at end of term? | Your group expects to stay put for most/all of the term. |
| Exit fees | A common pain point when households change or you need to switch again. | Exit fee amount and whether it applies per fuel (gas + electric). | You’re confident you won’t need to change before the term ends. |
| Payment method | Monthly Direct Debit can smooth cashflow, which helps bill splitting. | Direct Debit vs receipt of bill vs prepay; any discounts/requirements. | You want predictable payments and fewer arrears arguments. |
| Meter compatibility | Some deals depend on meter type (smart/prepay) or may restrict switching. | Is a smart meter required? Any limits for prepayment meters? | You know your meter setup and can provide accurate details. |
Cheapest fixed deal checklist (shared houses)
- We compared using the same payment method across deals.
- We used 12-month usage (or agreed on a realistic estimate).
- We checked exit fees and agreed how we’d split them if needed.
- We confirmed the account holder and got housemate consent.
- We’re clear whether we have single-rate electricity (typical) or something else.
Who a fixed tariff usually suits (and who it doesn’t)
Often suits
- Stable group staying for 12+ months
- Households that want predictable budgeting
- People happy to pick a term and stick to it
May not suit
- High turnover house shares
- Situations where the account holder may change soon
- Anyone unable to risk exit fees
Important: If your landlord pays the energy bills (or it’s included in rent), tenants usually can’t unilaterally change supplier. If the household pays the bills directly, the named account holder can typically switch — but should get agreement from housemates to avoid disputes.
Costs, exclusions and common pitfalls in shared houses
These are the issues we see most often when people search for the cheapest fixed tariff for a shared house. They’re easy to miss — and can turn a “cheap” deal into a stressful one.
Exit fees when tenants change
Fixed tariffs often have early exit fees. If your group is likely to change, agree upfront how you’ll handle them and keep evidence of housemate consent.
Wrong meter or address details
Comparisons can be inaccurate if the meter type (smart/prepay) is wrong. For multi-occupancy buildings, ensure the supply address and flat/room details match your bill.
Direct Debit smoothing vs “true-up” bills
A low monthly Direct Debit can still lead to a catch-up bill later if usage is higher than expected. In a house share, that can cause tension — monitor usage and submit reads where needed.
Standing charges (especially electricity-only homes)
Standing charges apply regardless of usage. In low-occupancy periods (holidays, empty rooms), standing charges can be a big chunk of the bill — include them in any “cheapest” comparison.
Bills included in rent
If bills are included, you’re not the customer for the supply — switching may not be possible. If you suspect you’re paying indirectly and want clarity, ask for how the energy costs are handled.
Debt and switching blocks
Some debts can affect switching, especially in certain situations. If there’s any dispute about arrears, resolve it with the supplier before starting a new contract.
House-share admin best practice: take and share meter reads (and photos) on move-in and move-out day. It’s one of the easiest ways to prevent bill disputes.
FAQs: fixed tariffs for shared houses (UK)
Can tenants in a shared house switch energy supplier?
Usually, the named account holder can request a switch. However, tenants should check the tenancy agreement and get agreement from housemates (and the landlord where required), especially if bills are included in rent or the landlord manages the supply.
What’s the difference between the cheapest unit rate and the cheapest overall tariff?
The cheapest unit rate doesn’t always give the cheapest total bill. Standing charges, exit fees, payment method, and your actual usage can make a tariff with a slightly higher unit rate cheaper overall for a shared house.
Are fixed tariffs cheaper for high-usage shared houses?
They can be, but it depends on the deal and your usage pattern. Shared houses often use more energy, so small differences in unit rates can matter — but a “cheap” fix with high exit fees or unsuitable terms may be poor value if the household changes.
Do HMOs get different energy tariffs?
Most HMOs are supplied on domestic tariffs if they have a standard domestic meter and domestic supply arrangement. However, the key issue is who the customer is (landlord vs tenants) and whether you have permission to switch.
What happens if we’re in a fixed deal and someone moves out?
The contract usually stays with the named account holder at that address until it ends, unless you switch or close the account. If you leave early, exit fees may apply. Many shared houses avoid disputes by agreeing upfront how fees and final bills will be split.
Can we switch if we have a prepayment meter?
Often yes, but your available options may be different from credit meters, and eligibility can vary. Use your postcode and meter details to compare what’s currently available and read the tariff terms carefully before starting a switch.
Does the Ofgem price cap apply to fixed tariffs?
The Ofgem price cap limits prices for default tariffs (including many standard variable tariffs), not fixed tariffs. Fixed deals have their own rates and terms set by suppliers, so you need to compare and check the contract details.
What details do I need to compare fixed tariffs accurately for a shared house?
At minimum: postcode, whether you pay by Direct Debit or another method, and your meter type (smart/traditional/prepay). For best accuracy, use your last 12 months’ kWh usage from bills or smart meter data.

How we assess “cheapest fixed energy tariff” for shared houses
We can’t publish live tariff names or rates on this guide page because prices and availability change frequently. Instead, this page explains how to judge which fixed tariff is cheapest for a shared house when you run a comparison.
- Cheapest means the lowest estimated annual cost for your postcode and circumstances, not the lowest unit rate in isolation.
- We prioritise comparisons that hold these constant: postcode/region, meter type (smart/traditional/prepay), payment method, and fuel (electric-only vs gas + electric).
- We highlight shared-house risks: exit fees, contract length, occupancy changes, and bill-splitting practicality.
Limitations: Any “cheapest” result can change with your usage, the date you compare, regional price differences, and eligibility rules (including meter requirements). Always read the tariff’s Key Facts / terms and confirm you have authority to switch at the property.
