Fast answer: what’s usually cheapest for UK home workers?
For most people who work from home in the UK, the cheapest electricity tariff is typically a competitive single-rate tariff (same unit price all day) unless you can shift a large chunk of usage into cheaper off-peak hours with a compatible meter.
Key takeaways
- Single-rate often wins for daytime-heavy routines (laptops, monitors, lights, cooking).
- Economy 7 can be cheaper only if you can move roughly 40%+ of electricity into night rates (varies by prices).
- Smart TOU tariffs can be great if you can shift flexible loads (washing, dishwasher, EV charging, some heat pumps) into cheap windows.
- The “cheapest” depends on region, meter type, payment method, standing charge, and exit fees.
Quick self-check (30 seconds)
- Do you have a smart meter?
- If yes, you may be eligible for TOU tariffs. If not, your best bet is usually a strong single-rate deal.
- Can you use appliances overnight?
- If no (noise, safety, tenancy rules), Economy 7 is less likely to be cheapest.
- Is your standing charge high?
- High standing charges can wipe out unit-rate savings for low-to-medium users.
Important: “Cheapest tariff” is not one national plan. Electricity prices vary by distribution region (your postcode), and your meter configuration (single rate, Economy 7/10, smart). Always compare using your annual kWh if you can (from bills or your in-home display/app).
Compare tariffs built around your home-working routine
Tell us your postcode and basic details and we’ll help you compare whole-of-market options for home electricity (not business energy). If you know your usage, keep it handy — it improves accuracy.
What affects your price most
- Where you live (network region via postcode)
- Payment method (Direct Debit often lowest)
- Meter type (single rate vs Economy 7 vs smart TOU)
- Standing charge vs unit rate balance
- Tariff length and any exit fees
Home-working usage to watch
- Daytime cooking (kettle, oven, hob)
- Extra lighting/heating controls
- IT equipment (laptop/desktop, monitors, router)
- Laundry cycles moved from weekend to weekdays
Tip: If you’re not sure about your meter type, check your bill for “single rate”, “two rate”, “Economy 7”, or look at your meter display. Smart TOU tariffs usually require a communicating smart meter.

Tariff types: which one suits home workers?
Home working tends to increase weekday daytime electricity. That usually favours a strong single-rate tariff — but if you can shift flexible usage (laundry, EV charging, immersion heater, some heat pumps) to off-peak, you may do better on Economy 7 or a smart TOU tariff.
| Tariff type | Best for | Watch outs | What to check before switching |
|---|---|---|---|
| Single-rate | Most home workers; predictable costs; daytime use | High standing charge can hit low users | Standing charge, unit rate, exit fees, tariff end date |
| Economy 7 (day/night) | People with storage heaters / heavy overnight use | Day rate can be much higher; timing differs by region/meter | Your off-peak hours, night vs day rate gap, ability to shift usage |
| Smart TOU (e.g. cheap windows) | Flexible users; EV owners; automation-friendly homes | Rates can be more complex; peak rates may be high | Smart meter compatibility, peak pricing, how you’ll shift load |
| Tracker / variable | Risk-tolerant households watching prices | Prices can rise; budgeting harder; not always available | How prices are set, notice periods, your budget flexibility |
Decision checklist: likely best match
- Choose single-rate if you’re home in the day and can’t (or won’t) run major loads overnight.
- Consider Economy 7 if you have storage heating, an immersion heater on a timer, or you can reliably shift big loads to night hours.
- Consider smart TOU if you can schedule loads (EV, laundry, dishwasher) and you understand peak pricing.
- Be cautious with trackers/variable if predictable monthly bills matter most.
Who this guide is for (and who it isn’t)
It suits you if: you work from home full-time or part-time, pay your own electricity bills, and want the cheapest realistic option without surprises.
It may not fit if: your energy is included in rent, you’re switching for a business meter, or you’re on a complex heat network (district heating).
Tenants: you can usually switch supplier if you pay the bills, but check your tenancy agreement for any admin requirements and ensure you can provide meter readings at move-in/move-out.
Two realistic cost scenarios (with numbers)
These examples show how “cheapest” can change for home workers depending on when you use electricity. They are illustrative estimates only — your actual quotes will vary by region, supplier, payment method and tariff availability.
Assumptions for both scenarios: Electricity-only comparison; 365 days; standing charge assumed the same across options to isolate unit-rate differences (in real comparisons it often differs). VAT included. These are not predictions of market prices.
Scenario A: daytime-heavy home worker (single-rate usually wins)
- Annual use: 3,100 kWh
- Daytime share: ~75% (working at home, cooking at home)
- Night/off-peak share: ~25% (some laundry on delay-start)
| Option | Unit rates used | Estimated annual unit cost |
|---|---|---|
| Single-rate | 26p/kWh | 3,100 × £0.26 = £806 |
| Economy 7 | Day 30p / Night 14p | 2,325 × £0.30 + 775 × £0.14 = £806 (about the same) |
In this scenario, Economy 7 only matches single-rate because the user can’t shift enough energy into the cheaper window. If the day rate were higher (or night share lower), Economy 7 would likely cost more.
Scenario B: home worker + EV (off-peak tariff can win)
- Annual use: 4,800 kWh
- Daytime share: ~55%
- Off-peak share: ~45% (EV charging + timed appliances)
| Option | Unit rates used | Estimated annual unit cost |
|---|---|---|
| Single-rate | 26p/kWh | 4,800 × £0.26 = £1,248 |
| Off-peak / TOU-style | Peak 29p / Off-peak 12p | 2,640 × £0.29 + 2,160 × £0.12 = £1,026 |
Here, cheaper off-peak energy makes a bigger difference because nearly half of usage is moved to the low-rate window. The trade-off is that peak/day rates can be higher, so it only works if you genuinely shift load.
Reality check: Standing charges and regional differences can change the outcome. Use these scenarios as a guide to what to measure (your day vs night share), not as a promise of savings.
Costs, exclusions and common pitfalls (UK-specific)
1) Standing charge can outweigh unit savings
If you’re a low user (for example, a flat with efficient appliances), a tariff with a slightly higher unit rate but lower standing charge may work out cheaper overall. Always compare the estimated annual cost, not just p/kWh.
2) Economy 7 timings aren’t universal
Off-peak hours depend on your meter setup and region (and sometimes change with BST/GMT). Before switching, confirm the exact off-peak window and whether it matches when you can run appliances.
3) Smart TOU tariffs can have expensive peak rates
Time-of-use deals can be excellent for EVs and flexible homes, but the peak unit rate may be higher than standard tariffs. If home working means you’re using energy at peak times, TOU may cost more unless you can shift significant load.
4) Exit fees and contract end dates
Fixed tariffs sometimes include exit fees. If you’re near the end of your contract, switching at the right time can avoid unnecessary charges. Check your current supplier’s terms and your bill/online account for your end date.
5) Meter type and eligibility
Some tariffs require a smart meter that can send half-hourly readings. If your smart meter isn’t communicating, your options may be limited until it’s fixed. Economy 7 requires a two-rate setup.
Home-working energy myth to ignore
“I work from home so I need an off-peak tariff.” Not necessarily. Working from home often increases daytime usage, so a good single-rate tariff can be the lowest-cost, lowest-hassle option.
Safety note: If you run appliances on delay-start overnight, follow manufacturer guidance and consider risk (ventilation, fire safety, tenancy rules). Cheapest isn’t worth unsafe habits.
FAQs: cheapest electricity for home workers (UK)
Is there a dedicated “work from home” electricity tariff?
Not usually. Suppliers rarely label tariffs specifically for home workers. The practical approach is to choose the tariff structure that matches when you use energy: single-rate for daytime-heavy use, or TOU/Economy 7 if you can shift usage to off-peak.
What’s the biggest mistake home workers make when switching?
Choosing a tariff based on a low off-peak unit rate without checking the peak/day rate and the standing charge. If you’re home all day, expensive peak rates can outweigh the off-peak benefit.
Do I need a smart meter to get the cheapest tariffs?
No. Many competitive single-rate tariffs don’t require a smart meter. However, smart meters can unlock TOU tariffs and make comparisons more accurate (because you can see when you use energy). Eligibility varies by supplier.
I’m on prepayment — can I still get a cheap deal?
Sometimes, but options can be more limited and prices can differ from Direct Debit tariffs. If you can switch to Direct Debit, it may open up more deals, but it depends on your circumstances and supplier criteria.
If I have solar panels, what should I look for?
Working from home can help you use more of your solar generation in the day, reducing grid imports. Still compare tariffs on (1) import unit rate + standing charge and, if relevant, (2) export terms you’re eligible for. Export payments and eligibility differ by supplier and scheme.
Can I switch electricity supplier if I’m renting?
In most cases, yes — if you’re responsible for paying the bill. You typically don’t need the landlord’s permission, but you should keep records of meter readings and ensure the account is in your name. If bills are included in rent, you usually can’t switch.
Will switching affect my supply or cause downtime?
Switching supplier shouldn’t interrupt your electricity supply. Your network and meter stay the same; only the company billing you changes. Timelines and steps vary, and you should submit meter readings when asked.
What information makes comparisons more accurate?
Your postcode, payment method, meter type (single rate/Economy 7/smart), and your annual kWh. If you have Economy 7/TOU, a split of day vs off-peak usage helps too.

How we assess “cheapest for home workers”
We focus on what typically changes when someone works from home: higher weekday daytime demand and more frequent small appliance use. Our guidance is based on how tariffs are structured in Great Britain and what households can realistically shift to off-peak.
- We compare tariff structures (single-rate, Economy 7, TOU) and explain when each tends to be cheapest.
- We emphasise total cost (unit rate + standing charge) and practical constraints (meter compatibility, off-peak timings, lifestyle).
- We include scenario maths to show how day/off-peak shares change outcomes.
Limitations: We do not list a single “national cheapest tariff” because prices vary by region, payment method, and eligibility. Availability can change quickly. Always verify rates and fees on the supplier’s tariff information label (TIL) before agreeing.
