Cheapest energy tariff for home workers in the UK (how to find it)
There isn’t one single “cheapest tariff for home working” — the best value depends on when you use electricity, your meter type (single-rate, Economy 7, smart), and payment method. This guide helps you pick the right tariff type and compare whole-of-market options confidently.
- Fast route: compare tariffs by your meter and usage pattern (daytime vs evening)
- Home-working friendly choices: fixed, variable, and time-of-use (e.g. Agile-style)
- Includes real-world scenarios, pitfalls, and a switching checklist
Estimates shown are illustrative and will vary by region, supplier, meter type and how/when you use energy. Always check tariff terms, unit rates, standing charges and exit fees.
Fast answer: what’s the cheapest tariff for home workers?
For most UK home workers, the “cheapest” tariff is the one that matches your daytime electricity use (laptops, monitors, heating controls, cooking, hot water). The biggest cost levers are:
1) Your meter & tariff structure
Single-rate vs Economy 7 vs smart time-of-use can change what you pay for daytime energy.
2) Standing charge
If you’re at home more, unit rates matter — but standing charge is paid every day regardless.
3) Payment method & contract terms
Direct Debit is often cheapest; check fixed-term length and any exit fees.
Quick rule of thumb: If you use most electricity during weekday daytime (common for home workers), a competitive single-rate tariff is often better value than Economy 7. If you can shift heavy use to off-peak (EV charging, storage heaters, immersion), Economy 7 or time-of-use may win — but only with the right usage split.

How to choose a tariff when you work from home
Step 1: Work out your “home-working load”
Laptop and screens aren’t the big cost — heating and hot water usually are. Consider:
- Do you run electric heating or a heat pump during the day?
- Do you cook more at home (electric oven/hob)?
- Any daytime laundry/tumble dryer use?
- Do you have an EV or battery storage?
Step 2: Check your meter setup
Your meter affects which tariffs you can take and whether peak/off-peak rates apply.
- Single-rate
- One unit rate all day. Simple and often best if you use more electricity in daytime.
- Economy 7 (two-rate)
- Cheaper off-peak hours (often overnight) and higher day rate. Best if you can shift heavy use off-peak.
- Smart meter / time-of-use
- Prices can vary by half-hour or by set peak/off-peak windows. Can be great for flexible use, but riskier if you can’t shift demand.
Important: Economy 7 off-peak times vary by region and meter setup. Don’t assume it’s always midnight–7am — verify with your supplier before switching.
Tariff types compared (what suits home workers best)
Use this table to narrow your options before you compare prices. “Cheapest” depends on your usage pattern, region, and the tariff’s unit rates and standing charge.
| Tariff type | Best for home workers who… | Watch-outs | Meter needs |
|---|---|---|---|
| Fixed (single-rate) | Want predictable costs and use plenty of electricity during daytime. | May have exit fees; could miss future price drops. | Standard or smart meter |
| Variable (standard) | Need flexibility (moving house, uncertain plans) and can tolerate price changes. | Rates can change; not always best value long-term. | Standard or smart meter |
| Economy 7 (two-rate) | Can shift heavy use to off-peak (EV charging, storage heaters, immersion heater). | Day rate can be much higher; off-peak hours vary by region/meter. | Economy 7 capable meter |
| Time-of-use (smart) | Are flexible: can move appliance use away from peak times and track costs. | Peak prices can be high; needs active management; not ideal for predictable daytime use you can’t shift. | Smart meter required |
Decision checklist (quick)
- Mostly home in the day? Prioritise a low daytime unit rate and sensible standing charge.
- Can you shift usage? Consider Economy 7 or time-of-use only if you can move meaningful kWh off-peak.
- All-electric home? Small price differences can matter more; compare carefully.
- Moving soon? A flexible option may suit better than a longer fix with exit fees.
Who it suits / who it doesn’t
Often suits: Mon–Fri home workers with steady daytime use; households with electric cooking; people who want predictable bills.
Often doesn’t: Storage-heater homes on Economy 7 (unless you keep two-rate); anyone unable to handle peak pricing on time-of-use.
Costs, exclusions and common pitfalls (especially for home workers)
Home working changes when you use energy. These are the traps that most often stop people getting the cheapest overall deal.
Standing charge shock
Even if you’re careful with usage, standing charges add up. Compare on total estimated annual cost, not just unit rate.
Economy 7 mismatch
If you’re home in the day, the higher day rate can wipe out off-peak gains unless you shift a lot of kWh overnight.
Time-of-use complexity
Great if you can avoid peak windows; risky if you need heating/cooking at peak times. Check what happens at peak.
Exit fees: Many fixed tariffs charge an exit fee if you leave early. If your job or tenancy is likely to change, weigh flexibility against a slightly cheaper rate.
Payment method: Some suppliers price differently for Direct Debit vs pay-on-receipt/prepayment. The “cheapest” quote may assume Direct Debit.
Two realistic scenarios (illustrative numbers)
These examples show why tariff structure matters for home workers. Figures are illustrative (not a quote) and exclude VAT nuances; supplier terms vary.
Scenario A: Daytime-heavy home worker (single-rate often wins)
Assumptions: 3,600 kWh/year electricity, no EV. 70% used in daytime (weekday working hours + evening), 30% overnight.
- Single-rate example: 24p/kWh + 55p/day standing charge
- Economy 7 example: 30p/kWh day + 14p/kWh night + 55p/day standing charge
Estimated annual energy (kWh) cost:
Single-rate: 3,600×£0.24 = £864
Economy 7: (2,520×£0.30) + (1,080×£0.14) = £907.20
Standing charge adds ~£200.75/year in both examples (55p×365).
Scenario B: Home worker with EV charging overnight (two-rate may win)
Assumptions: 5,000 kWh/year electricity including EV. 45% day, 55% night (EV + appliances shifted overnight).
- Single-rate example: 24p/kWh + 55p/day standing charge
- Economy 7 example: 30p/kWh day + 14p/kWh night + 55p/day standing charge
Estimated annual energy (kWh) cost:
Single-rate: 5,000×£0.24 = £1,200
Economy 7: (2,250×£0.30) + (2,750×£0.14) = £1,060
In this pattern, cheaper night usage can outweigh the higher day rate.
Caveat: The break-even point depends on the exact day/night rates and your real split. If you don’t know your split, start with a single-rate comparison and only consider Economy 7/time-of-use if you can confidently shift usage.
FAQs: cheapest energy tariffs for home workers
Is there a specific “work from home” energy tariff in the UK?
Usually not. Suppliers rarely label tariffs for home workers. Instead, you choose between tariff types (fixed/variable/Economy 7/time-of-use) and compare the actual unit rates and standing charges for your region and meter.
Will working from home make my bill much higher?
It can, but it depends what changes. Electronics are often modest; heating and hot water are bigger. If you heat the home in daytime or cook more, you may use more kWh. The best way to see the impact is to compare your last few bills (kWh and £) before and after home working.
Is Economy 7 good for home workers?
Only if you can shift a meaningful share of electricity to off-peak hours (for example EV charging, immersion heating overnight, storage heaters). If you’re using electricity mainly in daytime, Economy 7’s higher day rate can be poor value.
Do I need a smart meter for the cheapest tariffs?
Not always. Many competitive fixed and variable tariffs work with standard meters. However, time-of-use tariffs typically require a smart meter because prices can vary by time, and readings need to be automatic.
Can I switch energy supplier if I rent?
In most cases, yes — if you pay the bills and the contract is in your name. If you have a landlord-supplied contract included in rent, your options may be limited. Always check your tenancy agreement and whether there are any practical constraints (like prepayment meters).
What should I compare to find the cheapest deal?
Compare: unit rate(s) (p/kWh), standing charge (p/day), tariff length, exit fees, payment method assumptions, and any discounts with conditions. The lowest unit rate isn’t always the lowest total cost.
Are cheaper tariffs always available in my area?
Not guaranteed. UK energy prices vary by region and supplier appetite, and some tariffs can be restricted by meter type, payment method, or smart meter requirements. Availability can change frequently.
Can I avoid standing charges?
Most mainstream tariffs include a standing charge. Some niche deals may reduce it but often compensate with higher unit rates or specific terms. If you’re comparing, focus on estimated annual cost and suitability rather than one headline figure.

How we assess “cheapest” for home workers
We don’t label a single tariff as cheapest for everyone. Instead, we focus on what changes for home-working households and the variables that most affect cost:
- Usage timing: daytime-heavy vs off-peak-shiftable use.
- Meter compatibility: single-rate, Economy 7, smart meter requirements.
- Total cost drivers: unit rate(s) + standing charge + contract terms (including exit fees where applicable).
- Regional pricing: availability and rates differ across Great Britain regions; quotes must be postcode-specific.
Limitations: Without your exact annual kWh and (for two-rate/time-of-use) your day/night or half-hourly split, any “cheapest” claim is only an estimate. Always confirm rates, standing charges and key terms on the supplier’s tariff information label before switching.
