About & terms
What the check is for
The Blackout Check is a playful planning tool. It turns your answers into practical suggestions for everyday disruptions. It is not a complete emergency assessment or a safety certification, and it cannot guarantee how your household will cope.
The guidance behind it
Our starting point is the UK Government’s Be Ready checklist, reviewed on 2 November 2026. Mostly Prepared is independent and is not government endorsed. Follow current instructions from local authorities and emergency services during an incident.
Your household is unique
The plan depends on your answers. Check quantities, equipment compatibility and individual needs before acting. The water figure is a drinking-only baseline; cooking, washing and pets need additional water. For essential care or medical equipment, agree a backup plan with your care team or equipment provider.
Shopping links
Amazon links currently open ordinary UK category searches. They are not affiliate links and we earn no commission. Search results are not a reviewed or endorsed product catalogue. Check the seller, product specifications and suitability before buying.
Your answers and saved plans
By default, quiz answers stay in the current page’s memory and are cleared when you refresh or leave. If you choose “Save progress on this device”, submitted answers, your position, challenge progress and checklist changes are stored in this browser for 30 days from the last saved update. You can delete that copy using “Delete saved progress” or start fresh on the welcome-back screen. Quiz answers are not submitted to a backend. Downloads and printed plans contain the household information you supplied; keep them somewhere suitable. Editing an answer recalculates the recommendations and clears manual sorted/later marks.
Using the site
You can use the check for free and save or print your household plan. External retailers and linked services have their own terms and privacy policies.
Privacy & cookies
Mostly Prepared uses optional analytics to understand which parts of the site people find useful.
Your quiz answers
Your answers are not submitted to us or included in our custom analytics events. By default they remain in page memory and are cleared when you refresh or leave. Optional saved progress stays in local storage on this browser, including household and support-needs selections, so use a private device. It expires after 30 days from the last update and is removed when you next open the check after expiry. Anyone with access to this browser could resume it. Delete it from the check at any time, or clear this site’s browser storage. Downloaded and printed plans stay with you.
Optional Google Analytics
If you accept analytics, we load Google Analytics 4, provided by Google, to measure page visits, device and browser information, broad location, referral sources and interactions such as starting or completing the quiz, reaching each of its five main chapters, downloading or printing a plan, starting, completing or sharing the Power Cut Game, following its link to the quiz, trying or completing a small-win challenge, clicking sharing options or Instagram image downloads, visiting our Instagram profile, and clicking a shopping link. Sharing and image-download events record button clicks, not confirmation that you posted or saved a file. Google receives technical information including your IP address when your browser connects; GA4 does not log or store individual IP addresses. Cookie identifiers help distinguish visits. We do not send your quiz answers, contact details or personalised shopping-list contents in our custom events.
Our basis for optional analytics is your consent. We disable Google signals and advertising personalisation in our tag. No Google Analytics script loads before you accept. Rejecting analytics does not limit the quiz. Changing to reject stops future measurement; it does not undo data already sent.
Your cookie choices
Accept or reject in the banner, or use at any time. We remember the choice on this browser for 180 days. Clearing browser storage or using a different browser may mean we ask again.
| Storage | Purpose and duration |
|---|---|
| mp-analytics-consent-v1 | Local storage holding your analytics choice and expiry. Used to honour that choice for 180 days; not used to track you. |
| mp-quiz-progress-v1 | Optional local storage for submitted quiz answers, progress, challenge completion or deferral, checklist changes and tracking flags. Saved only when requested, separately from analytics consent, for 30 days from the last saved update. Removed on deletion or when an expired copy is next read. |
| _ga and _ga_SR2W7RCWZD | Optional Google Analytics cookies for visitor and session measurement. Our tag sets a maximum lifetime of 180 days without renewing on each visit. Removed from this site when you reject analytics. |
Your light switch
We save your chosen light or dark appearance in local storage under mp-theme, so it follows you between pages and visits on this browser. This preference is separate from analytics and stays until you reset it or clear browser storage. It does not store quiz answers.
Google and other services
Google processes analytics data on its infrastructure, which can involve processing outside the UK. See Google’s privacy policy and how Google uses information from partner sites. Analytics report retention is controlled by our Google Analytics property settings. Website hosting also involves technical requests needed to serve pages, such as IP addresses and requested URLs. The site is hosted by Vercel; see Vercel’s privacy policy.
Shopping links take you to external retailers with their own privacy policies. They are currently ordinary links, with no affiliate commission.
Contact and your rights
For privacy questions or requests, contact Mostly Prepared at info@mostlyprepared.co.uk. Depending on the circumstances, you can ask to access, correct or erase personal data, restrict or object to its use, or request portability. You can withdraw analytics consent through Cookie settings. You can also raise concerns with the Information Commissioner’s Office.
