How does Uswitch free electricity work?

What is free electricity from Uswitch?

Uswitch’s Power Hours scheme gives you cashback for the electricity you use during specific time windows. It’s not free in the sense of zero meter reading—your supplier still charges you normally, and Uswitch refunds the cost of the units you consumed. According to the Uswitch Terms & Conditions (official scheme rules), the refund is calculated using your smart meter data and your electricity unit rate (or the Ofgem price cap if your supplier doesn’t provide a rate). Only the kWh cost is refunded; standing charges still apply.

For the November 2025 campaign, Uswitch offered 25 hours across five consecutive weekends, as reported by RVU (Uswitch’s parent company). Users picked either a morning (7am–12pm) or afternoon (12pm–5pm) slot each weekend.

How the reimbursement process works

• After a Power Hours event, Uswitch calculates your refund based on smart meter readings during the free period.
• It uses either your exact unit rate (from your supplier) or the Ofgem price cap, whichever applies.
• Earnings are added to your Uswitch account and can be withdrawn to your bank account or applied to your bill.

Why Uswitch offers free electricity

Uswitch makes money from commissions when users switch energy suppliers through its platform. Free electricity campaigns attract new users who connect their smart meters, which in turn makes future switching easier. It’s a retention and data play: the more users linked, the more accurate their switching recommendations become. The Uswitch Free Electricity Page (scheme homepage) pitches it as a reward for being a “smart meter connected user.”

The implication: Users who participate can offset a small portion of their electricity costs, but the real value lies in the switching recommendations enabled by data access.

How do I claim Uswitch free electricity?

Eligibility requirements

• You must have an active smart meter that sends half-hourly readings (Citizens Advice (smart meter information)).
• The smart meter must be connected to the Uswitch app via a secure API.
• You sign up for Uswitch (free) and download the app from the iOS App Store or Google Play.
• One claim per household per offer.

Step-by-step claim process via Uswitch app

1. Download the Uswitch app and create an account (free).
2. Connect your smart meter: use the in-home display code or a one-off bank card address check (Uswitch Free Electricity Page). No charge for either method.
3. Once connected, you’re automatically enrolled in Power Hours; future campaigns appear in the app.
4. For each event, activate the offer in the app before the free period starts. The November 2025 campaign required users to select their 5-hour weekend slots by the Friday before.
5. Use electricity normally during the free hours. The app tracks your usage.

What to do after claiming

No further action is needed. Uswitch calculates the refund automatically after the event. According to the Uswitch Media Centre (official press release), earnings are added to your account and can be withdrawn to your bank. A worked example from Uswitch: using a 3.5-hour oven plus a 2-hour electric hob on Christmas Day would earn about £2.87.

What this means: households that miss the sign-up window lose access. For the May 2026 offer, sign-up closes on 29 April 2026.

Is Uswitch free?

Does Uswitch charge for switching?

Uswitch does not charge consumers to use its comparison and switching service. Revenue comes from energy suppliers when customers switch through the platform.

How Uswitch makes money

Suppliers pay Uswitch a commission for each successful switch. The free electricity offers are an incentive to get users onto the app and connected via smart meters, which increases the likelihood of future switches.

Are there any hidden fees?

• No sign-up or subscription fees.
• No charge for connecting your smart meter.
• Cashback from Power Hours is not taxable (it’s a refund, not income).

The pattern: Uswitch’s business model relies on commissions, making the free electricity offer a calculated incentive for user engagement.

Is it safe to connect a smart meter to Uswitch?

How Uswitch accesses your smart meter data

Uswitch uses a secure, read-only API to pull half-hourly consumption data from your smart meter. It cannot control your meter or change your supply.

Security measures and data permissions

According to the Uswitch Free Electricity Page, the connection is authorised via an in-home display code or a one-off bank card check. The data is used only to verify eligibility for Power Hours and to calculate refunds.

Can I remove access later?

Yes. You can disconnect your smart meter from the Uswitch app at any time in the account settings. This immediately stops data sharing.

The implication: for most households, the privacy risk is low. The API is read-only and revocable. No bank details are stored on Uswitch’s side after the address check.

How does Uswitch free electricity compare to other free electricity offers?

Uswitch vs British Gas free electricity

British Gas has offered free electricity on Sundays in the past, but it’s a different model: British Gas directly credits your bill with the cost of units used during the free period. Uswitch’s cashback is refunded to your bank account or bill after the event. British Gas offers do not require a smart meter connection through a third-party app.

Uswitch vs Octopus free electricity

Octopus Energy’s “Free Electricity” sessions (e.g., on Christmas Day 2024) directly deduct the cost from your bill. Octopus uses its own customer base and doesn’t require a separate app. Uswitch, by contrast, works with any supplier as long as you have a smart meter and the Uswitch app connected.

Which offer gives the best value?

Two patterns, one trade-off: Octopus and British Gas give immediate bill credit, but only to their own customers. Uswitch works across suppliers, but the refund comes as cashback, not a direct bill reduction. For households that switch suppliers regularly, Uswitch may offer more flexibility.

Pros and cons of Uswitch free electricity

What this means: The pros slightly outweigh the cons for households that already use the Uswitch app, but occasional users may find the setup effort not worth the modest reward.

Step-by-step walkthrough: How to claim Uswitch free electricity

1. Check your smart meter – Ensure it’s a SMETS1 or SMETS2 model that sends half-hourly readings. Most modern smart meters qualify.
2. Download the Uswitch app – Available on iOS and Android. Sign up for a free account.
3. Link your smart meter – Use the in-home display code or a one-off bank card address check. No charge.
4. Watch for campaign notifications – Power Hours appear in the app with limited sign-up windows.
5. Activate the offer – Tap “Activate” for the upcoming event before the deadline.
6. Use electricity as normal – The app records your usage during the free hours.
7. Receive cashback – Uswitch calculates and credits your account within 30 days. Withdraw to your bank.

The trade-off: the more often you participate, the more you earn—but missing a sign-up window means zero payout for that event.

Timeline of Uswitch free electricity campaigns

The pattern: Uswitch has run free electricity campaigns around holidays and weekends since at least 2024, but no official commitment to continue beyond 2026 exists.

Confirmed facts and what’s still unclear

Confirmed facts

• Uswitch pays cashback for electricity used during Power Hours events (Uswitch Terms & Conditions).
• Maximum cashback is £10 per household per event (MySideGig).
• Smart meter connection via the Uswitch app is mandatory (Uswitch Free Electricity Page).
• Cashback covers only kWh costs, not standing charges (Uswitch T&Cs).
• Withdrawal to bank account is possible after calculation (Uswitch Media Centre).

What’s unclear

• Whether the programme will continue beyond 2026.
• Exact future event dates (no advance calendar published).
• Actual cashback processing time (reported up to 30 days, but users on Reddit (user community) report variability).

The balance of certainty: confirmed facts outnumber unclear items, but the lack of commitment beyond 2026 tempers the offer’s long-term appeal.

What users say about Uswitch free electricity

“Households can get eight hours of free electricity over the early May bank holiday weekend with Uswitch.”

– Uswitch spokesperson, via Uswitch News

“It’s not free electricity in the literal sense—you still pay your supplier, and Uswitch reimburses you later. The cap is small, so don’t expect a huge saving.”

– Reddit user, r/OctopusEnergy community discussion

Both perspectives confirm the same reality: Uswitch’s offer is a small, occasional cashback reward, not a fundamental shift in your energy costs.

For UK households looking to shave a few pounds off their electricity bill, Uswitch Power Hours can help—but only if you’re willing to link your smart meter and remember to activate each event. The real opportunity isn’t the £10 cashback; it’s the frictionless switching that Uswitch enables once it has your data. For households that rarely switch suppliers, the savings from Power Hours may be modest. For those already in the switching habit, the cashback is a nice bonus. The choice is clear: opt in and automate, or skip it and stick with your standard tariff. The £10 won’t change your life, but it might change your switching behaviour.
