Fast answer: what’s usually cheapest for home workers?
For most UK home workers, the cheapest overall electricity option is the tariff with the best combination of:
- Low unit rate (p/kWh) for day-time usage
- Competitive standing charge (p/day) (especially if you don’t use loads of electricity)
- No expensive peak windows that clash with your working hours
In practice, that often means a good value fixed tariff (for price certainty) or a well-priced variable tariff (for flexibility), unless you can shift a meaningful chunk of usage to off‑peak times with a smart time‑of‑use tariff.
If you work 9–5 at home
Prioritise low day unit rate and a sensible standing charge. Economy 7 can be poor value unless you use most power overnight.
If you can shift usage
A time‑of‑use (smart) tariff can be cheapest if you can move washing, dishwashing, EV charging or storage heating to cheaper hours.
If you rent or may move
Consider no-exit-fee options. The cheapest headline rate isn’t always best if leaving triggers fees.
Key caveat: There’s no single cheapest tariff for every home worker. Your cheapest option depends on your region, meter type, payment method and when you use electricity. This guide shows you how to choose—and gives worked examples.
Compare tariffs for your work-from-home pattern
To find the cheapest electricity tariff as a home worker, you need to compare on total estimated annual cost, not just the cheapest unit rate. Standing charges and peak/off‑peak pricing can change the result.
What to gather (2 minutes)
- Your postcode (pricing varies by region)
- Meter type: standard, Economy 7 or smart
- How you pay: monthly Direct Debit vs other methods
- Rough usage: last bill in kWh (if you have it)
Home‑worker “usage clues”
- More day-time kWh than a typical out‑all‑day household
- Extra small loads: monitors, router, laptop, lighting
- If you use electric heating, costs are driven by heating—not WFH gadgets
Tip: If your home has a smart meter, consider whether you can shift energy-hungry tasks (washing, tumble drying, dishwasher, immersion heater, EV charging) to cheaper hours. If not, a simple fixed tariff may be cheaper overall.

How to choose the cheapest tariff when you work from home
Home working can shift electricity use into the day-time. That matters because some tariffs reward off‑peak use, while others are designed for steady all‑day consumption.
1) Start with your meter type
- Standard meter
- One unit rate. Usually simplest for 9–5 home working.
- Economy 7
- Two rates: day and night. Best if you can use a large share overnight (often via storage heating, immersion heating, EV charging).
- Smart meter
- Enables time‑of‑use tariffs. Great if you can shift usage, but check peak prices carefully.
2) Compare on total cost, not one headline rate
- Standing charge can dominate for low-to-medium users.
- Two tariffs with the same unit rate can cost very different amounts due to standing charge.
- Some “cheap” off‑peak tariffs have very high peak rates (often weekday late afternoon / early evening).
3) Match tariff type to your risk/needs
- Fixed: price certainty for the term; may include exit fees.
- Variable: flexible; prices can change (often aligned with market changes).
- Time-of-use: can be cheapest if your schedule fits; requires more attention.
Two realistic home‑worker scenarios (with numbers)
These examples show how pricing structure can change what’s “cheapest”. They are illustrative, not a promise. Your actual rates vary by region and supplier.
Scenario A: Laptop + monitors, mostly day-time use
- Assumed use: 3,100 kWh/year electricity
- Assumed tariff: single-rate 24p/kWh, standing charge 55p/day
Estimated annual cost: (3,100 × £0.24) + (365 × £0.55) = £744 + £200.75 = £944.75
Why it fits: day-time unit rate is reasonable and there’s no punishing peak window.
Scenario B: Smart tariff with cheap off‑peak, but you can’t shift much
- Assumed use: 3,100 kWh/year, but only 15% off‑peak
- Assumed rates: peak 30p/kWh, off‑peak 12p/kWh, standing charge 55p/day
Estimated annual cost: (2,635 × £0.30) + (465 × £0.12) + £200.75 = £790.50 + £55.80 + £200.75 = £1,047.05
Why it may not fit: without shifting usage, the higher peak rate can outweigh cheap off‑peak hours.
Decision checklist: who these options suit
Often suits home workers
- You work at home most weekdays
- You want predictable bills
- You can’t (or don’t want to) chase off‑peak hours
Consider: a competitive fixed or simple variable tariff.
May suit home workers
- You have a smart meter
- You can shift heavy loads (EV, washing, tumble dryer)
- You’re happy to avoid peak windows if needed
Consider: time‑of‑use tariffs (check peak pricing).
Often doesn’t suit
- You’re on Economy 7 but don’t use much overnight
- You rent and may move soon (exit fees risky)
- You’re not sure your meter supports the tariff
Watch out for: high standing charges or fixed exit fees.
Home working vs electric heating: If you heat your home with electricity (panel heaters, storage heaters, heat pump), heating will dwarf typical WFH device use. In that case, tariff choice should focus on heating patterns and off‑peak potential, not laptops.
Tariff comparison: what matters most for home workers
Use this table to narrow down what’s likely to be cheapest for your situation. Always confirm the supplier’s current rates, term length, and any eligibility rules.
| Tariff type | Best for | What to check | Common downside |
|---|---|---|---|
| Fixed (single-rate) | 9–5 home working, predictable usage | Unit rate, standing charge, exit fees, term length | Less flexible if you move or prices fall |
| Variable | Renters, people who may move, flexibility | How/when rates change, standing charge, discounts for Direct Debit | Price can rise; budgeting can be harder |
| Economy 7 | High overnight use (storage/immersion/EV) | Night hours, day vs night split, day rate level, meter compatibility | Day rate can be high—bad for day-time home working |
| Smart time-of-use | You can shift heavy loads; you track usage | Peak windows, weekend pricing, standing charge, smart meter requirement | Peak rates may clash with home life (cooking time) |
Quick “cheapest likely” checklist
- Mostly day-time use? Prioritise the day unit rate (and avoid harsh peak pricing).
- Low-to-medium use? Standing charge becomes more important.
- Can you shift 25–40% off‑peak? Time‑of‑use becomes more attractive.
- On Economy 7 without storage heating/EV? Consider switching meter/tariff type where possible.
What to have ready when comparing
- Your annual kWh (or last 12 months of bills)
- Whether you have electric heating / EV / immersion heater
- Your typical schedule (home all day vs mixed)
- Any contract end date or exit fee on your current tariff
Costs, exclusions and common pitfalls (home-worker edition)
The “cheapest” electricity tariff can flip once you factor in meter constraints, payment method, and when you actually use power.
1) Standing charge shock
A low unit rate can be offset by a high standing charge. This is especially important if you’re a low user (for example, small flats, efficient appliances, mild heating needs).
2) Economy 7 not matching your routine
If you work at home during the day and don’t have storage heating/EV, the higher day rate can make Economy 7 more expensive overall—even if the night rate looks great.
3) Time-of-use peak windows
Some smart tariffs have expensive peak periods (often late afternoon/early evening). If your household cooks, runs laundry, or charges devices then, costs can rise.
4) Exit fees and moving home
Fixed tariffs can include exit fees. If you rent or plan to move, a slightly higher tariff with no exit fee can be the cheaper overall choice.
5) Payment method differences
Monthly Direct Debit often has the widest availability and best pricing. If you pay on receipt of bill or prepayment, the cheapest deal in ads may not apply to you.
6) Electric heating changes everything
If you heat with electricity, heating drives the bill. A “WFH tariff” doesn’t exist—focus on your heating profile and whether off‑peak rates can genuinely be used.
Reminder: Suppliers price by region (distribution area), and standing charges can vary significantly across the UK. Always compare using your postcode and meter type.
FAQs: cheapest electricity tariffs for home workers (UK)
Is there a special “work from home” electricity tariff in the UK?
Not usually. Suppliers don’t typically label tariffs specifically for home workers. The cheapest option depends on your day-time usage and whether you can shift energy to cheaper hours (if you have a smart meter).
Do home workers use significantly more electricity?
Often a bit more—especially during the day (lighting, cooking, devices). But the biggest drivers are still heating and hot water. If you have gas central heating, WFH electricity increases can be modest compared with electric heating homes.
What’s more important for cheapest tariffs: unit rate or standing charge?
Both. Unit rate dominates for higher users, while standing charge matters more for low-to-medium users. The cheapest tariff is the one with the lowest total estimated annual cost for your usage profile.
I’m on Economy 7 but I work at home—should I switch?
Possibly. If most of your electricity is used during the day (and you don’t have storage heaters or an EV), Economy 7 can be expensive because day rates are often higher. Check your day/night split (from bills or your in-home display) before changing anything.
Do I need a smart meter to get the cheapest deal?
Not necessarily. Many competitive fixed and variable tariffs don’t require a smart meter. But for time-of-use pricing (where rates vary by hour), a smart meter is usually required.
Will a time-of-use tariff always be cheaper if I work from home?
No. If you can’t move much usage away from peak times, a time-of-use tariff can cost more than a straightforward single-rate tariff. It tends to work best when you can shift high-load activities to off‑peak hours.
Are fixed tariffs worth it if prices might fall?
A fixed tariff trades potential future price drops for certainty now. Check exit fees: if you want the option to leave early, a fee-free or low-fee tariff can reduce the risk of locking in.
Can I switch supplier if I rent?
In most cases, yes—if you pay the energy bills and you’re not in a contract arranged by the landlord (uncommon for typical self-contained rentals). If you have a prepayment meter or you’re in debt to your supplier, switching may have additional rules.
What information should I enter to compare accurately?
Use your postcode, meter type (standard/E7/smart), payment method, and ideally your annual kWh from bills. If you don’t have kWh, you can still compare—but results will be less accurate.

How we assess “cheapest electricity tariff” for home workers
This guide is designed to help you make a good comparison decision. We focus on the factors that most often change which tariff is cheapest for home workers:
- Total estimated annual cost = (unit rate × estimated kWh) + (standing charge × 365)
- Timing of use (day vs night, and any peak windows for time-of-use tariffs)
- Eligibility constraints: meter type, smart meter requirement, payment method (e.g. Direct Debit), and region
- Risk and flexibility: tariff term, price change rules, and exit fees
Assumptions used in examples: We used simple arithmetic examples with plausible rates to illustrate why tariffs that look cheap can be costly for day-time home working. These are not market-wide averages and not a quote.
Limitations: Supplier prices change, and “cheapest” varies by region, meter, and your actual consumption. For time-of-use tariffs, your bill depends on your hour-by-hour pattern; a single annual kWh figure may not capture this.
UK sources we rely on
- Ofgem (UK energy regulator) — consumer guidance and rules
- Citizens Advice: energy — switching help and consumer rights
- GOV.UK — official government guidance where relevant
What we won’t do
- We won’t promise guaranteed savings—energy costs are estimates and depend on your home and behaviour.
- We won’t pretend one supplier is always cheapest—regional charges and tariff rules make that unlikely.
- We won’t recommend a tariff type without flagging the key trade-offs (peak pricing, exit fees, meter requirements).
