Estimates vary by supplier, region, meter type, payment method and eligibility. If your tenant pays the bills, they usually control switching.

Fast answer: what’s the cheapest energy tariff for landlords in 2026?

There isn’t one single “cheapest landlord tariff” across the UK. The lowest estimated cost depends on:

Who pays the bills

If the tenant is responsible, they usually choose the supplier and tariff. If the landlord pays (e.g. bills included), you can compare and switch.

Meter & payment type

Smart vs traditional, single-rate vs Economy 7, and direct debit vs prepayment can change rates materially.

Region & eligibility

Standing charges vary by region (and sometimes by network). Some deals are new-customer only or exclude certain meters.

Landlord reality check: In most standard tenancies where the tenant pays the supplier directly, landlords can’t force a switch or require a particular supplier. Where a property is empty (void period) and bills are in the landlord’s name, you can choose and switch.

Key takeaways (quick wins)

  • Don’t guess: get quotes using the property’s actual MPAN/MPRN (from a bill) if possible.
  • Direct debit is usually cheapest (but not always); prepayment tariffs can be higher and harder to change quickly.
  • Fixes can reduce uncertainty, but check exit fees and what happens if you sell or re-let.
  • Void periods: avoid expensive “deemed” rates by setting up an account promptly and choosing a tariff.

How to get the cheapest landlord energy tariff (step-by-step)

  1. Confirm who’s the “customer”. If the tenant pays the supplier, they’re the account holder and decide the tariff. If bills are included or it’s a void, the landlord (or agent) is usually the account holder.
  2. Identify meter setup. Note gas/electric, smart meter yes/no, Economy 7/10, and whether there’s a prepayment meter (PPM). If unsure, check the latest bill or tenancy check-in report.
  3. Use real consumption where possible. Annual kWh from bills beats estimates. If you don’t have it (new purchase/void), use a cautious estimate and revisit after a few reads.
  4. Compare like-for-like. Compare tariffs with the same payment method and contract length, and check standing charges (not just unit rates).
  5. Check tenancy impacts. If the tenant may switch mid-fix, consider whether you want the account in their name as soon as they move in. For landlord-paid bills, assess exit fees and how you’ll manage changeovers.
  6. Switch with accurate details. Wrong address formatting or missing flat numbers can delay a switch—especially in HMOs and blocks.

Tip for voids: The incumbent supplier may put you on a deemed contract when you take responsibility. This is often pricier than a chosen tariff. Set up the account and start a switch as soon as you have keys and meter details.

What you’ll need (and why it matters)

Postcode + full address (incl. flat number)
Used to match the supply point and avoid delays or wrong meter assignments.
Meter type (credit vs prepay, single-rate vs Economy 7)
Some tariffs aren’t offered on PPM or have different unit rates/standing charges for multi-rate meters.
Annual usage (kWh) or best estimate
“Cheapest” depends on usage: low usage can make standing charge more important; high usage makes unit rate more important.

Compare landlord tariff types (what’s “cheapest” depends on your situation)

Use this table to narrow down which tariff structure is likely to be lowest for your rental property. Always compare estimated annual cost (unit rate + standing charge), not just a headline unit rate.

Tariff type When it can be cheapest Watch-outs for landlords Best for
Fixed rate (12–24 months) If market prices rise or you want predictable bills during voids/bills-included lets. Exit fees; moving tenants; you may not want a long commitment if occupancy is uncertain. Landlords covering bills, longer void risk, stable tenancy lengths.
Variable (standard / tracker) If prices fall, or for short void periods where flexibility matters most. Rates can change; budgeting harder; some “tracker” products have specific rules. Short-term needs, quick switches, uncertain occupancy.
Economy 7 / multi-rate If the property genuinely uses a large share off-peak (storage heaters, timed hot water). If tenants use power mostly in the day, it can be more expensive than single-rate. All-electric flats with storage heating; informed usage patterns.
Prepayment meter tariff Sometimes the only immediate option if the meter is set to prepay and cannot be changed quickly. Can be pricier; may limit tariff choice; changing to credit meter can require checks and time. Where PPM is in place and tenant prefers/needs it; arrears situations.

Decision checklist: who the “cheapest” tariff approach suits (and who it doesn’t)

Likely to suit you

  • You cover bills during void periods and want to reduce deemed-contract exposure.
  • You run bills-included lets and need predictable costs.
  • You have accurate annual usage or can get it from prior bills.
  • You can pay by monthly direct debit and pass credit checks (where relevant).

May not suit you

  • The tenant is (or should be) the account holder and you want to control tariff choice.
  • There’s a prepayment meter and you need immediate change—options can be limited.
  • Your property is likely to be sold soon (exit fees may outweigh any benefit).
  • Address/meter records are unclear (new builds, split flats, HMOs) and need resolving first.

Reminder: A tariff that looks cheapest on unit rate can still cost more overall if its standing charge is higher—especially for low-usage properties or short voids.

Costs, exclusions and common landlord pitfalls (UK)

These are the most common reasons landlords end up paying more than expected—even after “finding a cheap tariff”.

1) Deemed rates during voids

When a property becomes your responsibility, the existing supplier can place you on a deemed contract. It’s legal, but often not the best value.

Fix: take meter readings on changeover day and start a switch quickly.

2) Standing charges dominate low use

For short voids or minimally-used homes, the standing charge can be most of the bill—so “cheapest unit rate” may not matter much.

Fix: compare estimated annual cost and check the daily charge.

3) Economy 7 mismatch

Economy 7 can be great for storage heaters. But if most use is daytime, it may cost more than single-rate electricity.

Fix: sanity-check day/night usage split before choosing.

Exit fees and tenancy timing

Fixed tariffs may charge exit fees if you leave early. If you expect to sell, change letting model, or transfer to a tenant shortly, a long fix can become costly.

Practical rule: if you’re only covering a 2–8 week void, flexibility can matter more than shaving a fraction off the unit rate.

Prepayment meters (PPM)

If a rental has a prepayment meter, tariff choice may be limited and unit rates can differ. Converting to a credit meter can take time and may require supplier approval.

Check: whether the tenant wants to keep PPM; don’t remove it without agreement.

Two realistic scenarios with numbers (illustrative estimates)

These examples show why “cheapest” depends on usage and standing charge. Figures below are illustrative and not a promise of available rates.

Scenario A: Void period (landlord paying) — low usage, standing charge matters

Assumptions: 45-day void; electricity only for lights/boiler controls; usage 120 kWh; single-rate electricity.

Option Unit rate Standing charge Estimated 45-day cost
Tariff 1 (lower unit, higher standing) 25p/kWh 70p/day (120×£0.25) + (45×£0.70) ≈ £61.50
Tariff 2 (higher unit, lower standing) 28p/kWh 50p/day (120×£0.28) + (45×£0.50) ≈ £56.10

What this shows: even with a worse unit rate, lower standing charge can be cheaper for low usage / short voids.

Scenario B: Bills included let — higher usage, unit rate matters more

Assumptions: 12 months; typical two-bed flat; electricity 2,900 kWh/yr and gas 12,000 kWh/yr; paying by monthly direct debit.

Option Elec (unit / standing) Gas (unit / standing) Estimated annual total
Tariff A (better unit rates) 24p / 60p 6.0p / 32p Elec: (2900×£0.24)+(365×£0.60)=£696+£219=£915
Gas: (12000×£0.06)+(365×£0.32)=£720+£117=£837
≈ £1,752
Tariff B (higher unit rates) 27p / 55p 6.7p / 30p Elec: (2900×£0.27)+(365×£0.55)=£783+£201=£984
Gas: (12000×£0.067)+(365×£0.30)=£804+£110=£914
≈ £1,898

What this shows: for higher annual use, unit rates can outweigh small standing charge differences.

Important: Prices in 2026 can change due to wholesale costs, network charges and supplier pricing. Treat any “cheapest” result as time-sensitive and re-check before you commit.

FAQs: landlord energy tariffs in the UK (2026)

1) Can a landlord choose the energy supplier for a tenant?

If the tenant is the bill payer (account holder), they normally choose the supplier and tariff. A landlord generally can’t insist on a specific supplier as a condition of tenancy, except in limited cases (for example, where energy is supplied as part of a communal or embedded arrangement).

2) What happens to energy when a tenant moves out?

The supply stays on. Responsibility for bills transfers based on who occupies/controls the property. During a void, landlords commonly become responsible and may be placed on a deemed contract with the existing supplier until a new account/tariff is set up.

3) Is there a special “landlord tariff” in the UK?

Usually no. Landlords typically use standard domestic tariffs, but the best option depends on whether you’re paying during voids, covering bills in rent, or leaving the tenant to choose.

4) Are prepayment meters more expensive for rental properties?

They can be. Some suppliers price PPM differently and the range of tariffs may be smaller. If you’re considering switching a PPM to credit mode or changing the meter, check timescales and tenant consent.

5) Can I switch supplier during a void if I don’t have recent bills?

Often yes, but it may be easier if you can confirm meter details and take accurate opening readings. In blocks of flats and HMOs, getting the correct meter serial number helps avoid delays.

6) Does a fixed tariff stop prices rising in 2026?

A fixed tariff means your unit rates and standing charges are fixed for the agreed term (subject to the contract). It doesn’t guarantee the “best deal” overall, and you may pay more if prices fall. Always check exit fees and contract terms.

7) What’s the difference between unit rate and standing charge?

The unit rate is what you pay per kWh. The standing charge is a daily fee. For low usage (common in voids), standing charge can be a major part of the bill—so compare total estimated cost, not just the unit rate.

8) Where do I check the rules on switching and supplier obligations?

Ofgem and Citizens Advice explain how switching works, including your rights and what to do if there’s a dispute. See sources below.

Editorial information

How we assess “cheapest”

We treat “cheapest” as the lowest estimated total cost for the user’s situation, using:

  • Electricity and/or gas unit rates (p/kWh) plus standing charges (p/day)
  • User inputs (postcode/region, meter type, payment method, usage)
  • Tariff eligibility constraints (e.g. meter compatibility, new customer criteria)

Limitations (what we can’t guarantee)

  • Prices and availability can change daily; some deals close without notice.
  • Estimated costs depend on consumption; real bills vary with weather and occupancy.
  • Standing charges vary by region and can change with industry updates.
  • Switching timelines can be affected by address/meter data issues.
