If you bought iolo software online you have a 14 day cooling-off right under the Consumer Contracts Regulations 2013 when the purchase is a distance contract. If you requested download or immediate execution of digital content and gave express consent and acknowledged losing the right to cancel, the 14 day right may not apply. Notify iolo with a clear statement to cancel. See the renewal cooling-off provisions under the Consumer Rights Act 2024 at Consumer Rights Act 2024 - cooling-off.
Required proof documents: order number, purchase email, license key or proof of payment. Applicable law: Consumer Contracts Regulations 2013 and Consumer Rights Act 2024.
iolo requires refund requests to be received by telephone or email within thirty (30) days of the purchase date. You must provide proof of purchase date, price, sales receipt and/or license key. Refunds are issued to the original card less a 15% processing fee and less any discounts or rebates. See iolo's sales and refund policy at iolostore sales-policy and iolo knowledge base.
Required proof documents: proof of purchase, license key, transaction receipt. Applicable policy: iolo sales and refund policy.
If iolo increases the price at renewal or changes the service materially you may have rights under the Consumer Rights Act 2015 and the Consumer Rights Act 2024 subscription rules to cancel. For each renewal cooling-off period the trader must provide a notice of the renewal and any refund entitlement. If the renewal notice is not provided, you may be entitled to cancel for unfair change.
Required proof documents: renewal notice, invoice showing new price, prior subscription details. Applicable law: Consumer Rights Act 2015 and Consumer Rights Act 2024.
If your subscription has a finite term that ends, cancellation is effective at term end by not renewing. If you want to stop future billing, turn off automatic renewal in My Account before the next period.
Required proof documents: account subscription details or invoice. Applicable law: contract terms and Consumer Rights Act 2015 regarding unfair contract terms.
iolo does not publish a specific policy for moving or change of circumstances. To request termination for such reasons contact [email protected] and provide supporting documents (for example, proof of sale of device). iolo's published refund exceptions and rules apply to refunds.
Required proof documents: Not published by iolo.
iolo does not publish specific rules for termination on death. If you need to close an account after the death of a subscriber contact [email protected] and provide a copy of the death certificate and proof of authority to act for the estate. iolo's public policy does not list this scenario explicitly.
Required proof documents: Not published by iolo.
iolo is known to offer retention discounts or special renewal prices in some cases. A published customer report described iolo emailing a half-price offer instead of providing a full refund. When you contact iolo ask for a retention offer, state the renewal charge you received, and request a price-match or discount. Use these steps: call support or email [email protected], reference your order and ask explicitly for a retention discount or cancellation with refund.
Use iolo public annual prices to calculate yearly saving by cancelling. Example calculations using iolo published annual prices:
Yearly saving examples when cancelling:
Cheapest real alternative (example): CCleaner Professional annual license at £19.95 per year. Switching from System Mechanic Pro (£44.30) to CCleaner Professional (£19.95) saves £44.30 - £19.95 = £24.35 per year.
Your cancellation and refund rights are framed by these UK rules: the Consumer Contracts Regulations 2013 give a 14 day cooling-off right for most distance purchases; the Consumer Rights Act 2015 requires services to be performed with reasonable care and skill and prohibits unfair contract terms; the Consumer Rights Act 2024 adds specific rules for subscription contracts including renewal cooling-off notices. See the 2024 text at Consumer Rights Act 2024 - cooling-off.
The Competition and Markets Authority (CMA) treats unclear auto-renewal practices and hard-to-cancel subscriptions as potentially unfair. If iolo refuses a lawful cancellation or refund, complain to iolo first, then contact Citizens Advice for next steps. For payment disputes use your card issuer for chargeback or Section 75 protection if the purchase was made by a qualifying UK credit card.
1) Send a clear written complaint to [email protected] or a registered letter to the postal address. 2) If unresolved, ask Citizens Advice for a mediation route or evidence pack. 3) Use Section 75 or a chargeback via the card issuer for qualifying payments. 4) Report suspected unfair practices to the CMA.
After cancellation verify your bank or card statement for final charges and any refund. iolo issues refunds to the original card less a 15% processing fee if the refund request met the 30 day rule. Keep the refund confirmation and final invoice.
Keep a copy of your license key and any download installers if you want to reinstall later. If you lose account access, contact [email protected] and provide proof of purchase to recover account details.
If you no longer want the software uninstall System Mechanic via Windows Settings - Apps - Uninstall and remove any iolo browser extensions if installed. Cancelled subscriptions do not always uninstall software; you must remove it yourself if you choose.
You can re-subscribe later via the iolo purchase pages. Any refunds already given do not guarantee future promotional pricing.
