Cheapest electricity tariff for home workers in the UK
If you work from home, the “cheapest” tariff depends on when you use power (day vs night), your meter type (standard, smart, Economy 7), and your payment method. Use this guide to narrow down the best tariff type for your pattern—then compare whole-of-market options.

Fast answer: what’s usually cheapest for home workers?
For many UK home workers, the cheapest electricity tariff tends to be a competitive single-rate tariff (one unit rate all day) unless you can reliably shift a meaningful chunk of use into cheaper off-peak hours on a multi-rate tariff.
Best fit for most
A single-rate tariff with a low standing charge (where possible) is often best if you use power steadily through the day (laptop, monitors, cooking, heating controls).
Best if you can shift usage
A two-rate tariff (e.g. Economy 7) can win if you can move big loads (EV charging, immersion heater, storage heating, some laundry) into the night window.
Worth checking carefully
Some smart “time-of-use” tariffs can be excellent for flexible users, but rates and rules vary. Always check peak pricing and eligibility before switching.
Key takeaway: The cheapest tariff for home working isn’t about “WFH deals” (they rarely exist). It’s about matching your day/night usage split, meter type, and standing charge to the tariff structure.

How to choose the cheapest electricity tariff when you work from home
Home working often increases daytime electricity (kettle, cooking, IT equipment, lights) and, for some homes, heating system running hours. The cheapest tariff is the one that best matches your timing and constraints:
Step 1: Check your meter + readings
- Standard / smart meter (single-rate)
- Most households. You pay one unit rate all day.
- Economy 7 / multi-rate meter
- Two (or more) rates. Night is cheaper; day rate is often higher. Times vary by region and supplier.
If you’re unsure, check your bill for “Day/Night” readings or ask your supplier whether you’re on a multi-rate meter.
Step 2: Estimate your day vs night usage split
A simple way to start:
- Mostly daytime (typical home worker): 85–95% day / 5–15% night
- Flexible with big loads: 60–80% day / 20–40% night
- EV or storage heating: can be 40–60% night (sometimes more)
If your night usage is low, Economy 7 often costs more overall because the day rate is higher.
Step 3: Compare beyond the headline unit rate
- Standing charge: paid daily regardless of usage
- Payment method: Direct Debit vs credit meter vs prepay can change pricing
- Exit fees: common on fixed tariffs; check before switching again
- Discounts / bundles: can end; read the tariff information label
Step 4: Choose your risk level (fixed vs variable)
- Fixed tariff
- Unit rate/standing charge typically locked for a set term. May include exit fees. Often preferred for budgeting.
- Variable tariff
- Rates can change. Often more flexible (usually no exit fees), but less predictable.
Two realistic home-working scenarios (with numbers)
Scenario A: Typical home worker (mostly daytime)
Assumptions (example only): 3,100 kWh/year electricity, 90% day / 10% night. Standing charge 55p/day.
| Tariff type | Example rates | Estimated annual cost |
|---|---|---|
| Single-rate | 24p/kWh | ~£1,046 |
| Economy 7 (two-rate) | Day 30p/kWh, Night 14p/kWh | ~£1,189 |
In this pattern, Economy 7 is often worse because the higher day rate outweighs cheaper night units.
Scenario B: Home worker with flexible loads (meaningful night use)
Assumptions (example only): 4,200 kWh/year electricity, 65% day / 35% night (e.g. EV charging or storage heating). Standing charge 55p/day.
| Tariff type | Example rates | Estimated annual cost |
|---|---|---|
| Single-rate | 24p/kWh | ~£1,310 |
| Economy 7 (two-rate) | Day 30p/kWh, Night 14p/kWh | ~£1,259 |
With higher night usage, Economy 7 can start to beat single-rate—but the break-even point depends on your exact rates.
Important: The rates above are illustrative to show the mechanics. Real tariffs vary by region (distribution area), supplier, meter type, and payment method. Always compare using your postcode and meter details.
Tariff comparison table: which type suits a home worker?
Use this to shortlist a tariff type before you compare actual deals. (Then confirm by checking the full tariff information and your expected kWh usage.)
| Tariff type | Best for | Watch-outs | Quick rule of thumb |
|---|---|---|---|
| Single-rate (fixed or variable) | Most home workers with steady daytime use | Standing charge can dominate if you use little overall | If you can’t shift usage to night, start here |
| Economy 7 (two-rate) | EV charging, storage heaters, immersion heater on timer | Day rate usually higher; night times vary; not ideal for daytime-heavy use | Often needs ~25–40% night usage to compete (varies) |
| Smart time-of-use (multi-rate) | Flexible households that can avoid peak hours | Peak rates can be high; requires smart meter; rules differ per supplier | Good if you can automate heavy loads off-peak |
| Prepayment (PAYG) | If you prefer to budget by topping up | Tariff availability can be narrower; smart PAYG varies by supplier | Compare carefully—payment method affects pricing |
Decision checklist (who it suits / who it doesn’t)
A single-rate tariff usually suits you if…
- You work from home most weekdays (daytime-heavy use)
- You don’t have an EV, storage heaters, or an immersion heater on a timer
- Your usage is fairly consistent and you want simpler bills
- You want to avoid timing rules and peak pricing
Economy 7 / time-of-use may suit you if…
- You can shift a significant share of usage to night/off-peak
- You can automate loads (EV charging schedule, timers)
- You understand the off-peak hours for your tariff
- You’ve checked your day rate isn’t too high for your home-working routine
If you rent: you can usually switch electricity supplier, but check your tenancy agreement and ensure you won’t be charged for returning to the original supplier at the end of your tenancy.
Costs, exclusions and common pitfalls (home-working edition)
These are the issues that most often stop a “cheap” electricity tariff being cheap in real life.
1) Standing charge shock
If you’re a low user (e.g. small flat) the standing charge can represent a large share of your bill. Comparing only unit rates can mislead.
2) Economy 7 day rate is higher
Home working pushes usage into daytime. If you don’t hit enough off-peak kWh, two-rate tariffs can cost more overall.
3) Regional differences
Electricity rates vary by region (your distribution network area). A tariff that’s “cheapest” nationally may not be cheapest for your postcode.
4) Exit fees and contract terms
Fixed tariffs may charge exit fees if you switch early. If you want flexibility, check this before you commit.
5) Smart meter eligibility
Some time-of-use tariffs require a working smart meter and half-hourly readings. If you don’t have one, your options may be limited.
6) Working from home changes your profile
If you recently moved to home working, your annual kWh may have increased. Make sure your comparison uses updated usage so estimates aren’t under-stated.
Quick self-check: If your “cheap” option relies on changing habits (e.g. doing laundry at 2am), assume you’ll only stick to it some of the time. Build that into your choice.
FAQs: cheapest electricity tariffs for home workers
Is there a specific “work from home” electricity tariff in the UK?
Usually not. Suppliers typically price by tariff type (single-rate, Economy 7, smart time-of-use), payment method, and region—not by whether you work from home. The best approach is to pick a tariff structure that matches your day/night usage.
Are fixed tariffs cheaper than variable tariffs for home workers?
Not always. Fixed tariffs can help with budgeting and may be competitive, but you’ll need to compare the full cost (unit rate + standing charge) and check exit fees. Variable tariffs are often more flexible, but rates can change.
Do I need a smart meter to get the cheapest tariff?
No—many competitive tariffs are available without a smart meter. However, some time-of-use tariffs require a smart meter and (often) half-hourly data. If you’re considering these, confirm eligibility before switching.
What’s the break-even for Economy 7 if I work from home?
It depends on your exact day and night rates. As a rough guide, Economy 7 tends to suit homes that can push a meaningful chunk of electricity into off-peak (often around a quarter to a third of usage or more). If you’re mostly daytime-heavy, it may cost more.
Will switching electricity supplier interrupt my supply?
In normal circumstances, no. Switching is an administrative process—your electricity keeps flowing through the same wires. You should still take meter readings when asked to help ensure your final and first bills are accurate.
Can tenants switch electricity tariffs if they work from home?
Often yes, as long as you pay the bills and your tenancy agreement doesn’t restrict switching. If you switch, keep records and be prepared to switch back at the end of the tenancy if required.
Does paying by Direct Debit make electricity cheaper?
It can. Some suppliers price differently depending on payment method. When comparing, ensure you select the same payment method you plan to use so the estimate is meaningful.
What if I don’t know my annual kWh usage?
You can still compare using a recent bill (it often shows annual usage or recent consumption). If you’ve started working from home recently, consider that your electricity use may have increased—update your estimate accordingly to avoid underestimating costs.

How we assess “cheapest” for home workers
We focus on total estimated annual cost (unit rates + standing charges) and whether the tariff structure matches typical home-working usage patterns.
- Tariff structure fit: single-rate vs multi-rate vs time-of-use
- Eligibility constraints: meter type, smart meter requirements, payment method
- Risk factors: fixed vs variable, exit fees, contract length
- Regional pricing: postcode-based availability and network costs
Assumptions and limitations (read this)
- All worked examples on this page are illustrative and use simple arithmetic to demonstrate how day/night splits affect cost.
- Real-world “cheapest” outcomes depend on your exact tariff rates, standing charge, region, meter type, and actual usage.
- We don’t assume any guaranteed savings. Switching decisions should be based on the tariff information provided during comparison and your household’s needs.
- Economy 7 and time-of-use off-peak hours differ and may not align perfectly with your routine. Always confirm the times on the tariff details.
