How to Claim and Protect Your Full 15GB Free Google Storage

Claiming your full 15GB Google storage is now an active task rather than a default, after 9to5Google confirmed on 14 May 2026 that new Google Accounts get just 5GB unless you link a phone number. Google has since told Android Authority it is “testing a new storage policy for new accounts created in select regions” — corporate language for a quiet halving of the most famous free tier in consumer tech. Existing accounts still have 15GB today, but the smart move is to lock yours in, clean it out and decide what you actually need before the cap becomes universal.

Why you should act now, not when the cap arrives

If you have a UK Google Account that already shows 15GB, nothing has changed for you yet — and that is exactly why this is the right moment. Google’s pattern with consumer-storage changes, going back to the 2021 Google Photos reversal, is to grandfather existing accounts and apply new rules to new ones. The risk is not that your number drops to 5GB overnight; it is that you sleepwalk into a 5GB future on a secondary account, a child’s account or a new device set up under a fresh identity — including the kind of fresh sign-in you would do on a new Googlebook laptop — and only notice when Gmail stops receiving mail. Treat the 15GB you have as something to protect rather than assume. Our full breakdown of the policy shift sits in the Google free storage 5GB analysis — this guide is the practical companion.

The cap matters because 15GB is shared, not per-app. Five gigabytes of Gmail is a year or two of normal email; five gigabytes of Photos is a single weekend of high-resolution shooting. A 5GB account is not a smaller version of a 15GB one — it fills before you have done anything interesting with it. The four steps below get you to a secured, audited, lean 15GB account in under an hour.

Step 1: Lock in the full 15GB by linking a phone number safely

Google’s stated route to the full allowance is a verified phone number on the account. On an existing 15GB account this is belt-and-braces insurance: it satisfies the new policy’s condition in advance, so a future migration cannot quietly demote you. Go to myaccount.google.com, open Personal info, then Contact info, then Phone, and add a number if one is not already there. Verify it with the SMS code. On a new account, add the number during sign-up rather than skipping it.

Do it safely. Add the number for account recovery and verification only, not for personalised ads or “people who have your number can find you” discovery — both of those toggles live under the same Phone settings and can be turned off without losing the storage benefit. If you are uneasy handing Google a primary mobile number, a UK pay-as-you-go SIM used solely for verification is a legitimate middle ground. What you should not do is use a disposable online number; Google increasingly rejects VoIP ranges, and a number it later flags can put a hold on the account. The honest read: this is a data trade, the same identity-harvesting logic we flagged around Google’s wider subscription bundling. Linking a number you control is the pragmatic call; doing it on your terms is the point.

Step 2: Audit what is actually eating your Drive, Gmail and Photos space

Before you delete anything, see where the gigabytes have gone. Open one.google.com/storage/management — this is the single dashboard Google uses across all three products, and it breaks usage down by Gmail, Drive and Photos with the largest items surfaced first. On mobile, tap your profile picture inside Drive, Photos or Gmail and choose Manage storage to reach the same place. Tap Usage details to see the split.

For most UK users the culprit is one of three things: years of Gmail with fat attachments, original-quality photo backups, or forgotten Drive files and old WhatsApp backups (yes, WhatsApp Google Drive backups now count against the quota). The storage manager will tell you which within seconds. Note the worst offender — that is where Step 3 should focus first. Do not skip the audit and start randomly deleting; you will spend an hour clearing 200MB of email while 6GB of Photos sits untouched.

Step 3: Free real space — the high-yield deletions first

Work top-down by size. In Gmail, the search bar is your best tool. Type has:attachment larger:10M to surface heavy emails, or older_than:2y has:attachment for ancient ones; tick and delete the obvious junk. Then — and this is the step people forget — empty the Gmail Bin, because deleted mail keeps counting for 30 days otherwise. Do the same in Drive: open Storage in the left menu so files list largest-first, bin the dead weight, then empty the Drive Bin too.

Photos is usually the big win. Use the storage manager’s built-in Review and delete tool, which finds blurry shots, large videos and screenshots automatically — clearing screenshots alone often recovers a gigabyte. Empty the Photos Bin to finalise it. One blunt move worth knowing: switching Photos backup from Original quality to Storage saver stops new photos eating the quota at full size, though it will not retroactively shrink what is already there. After every clear-out, give Google a few minutes — usage figures lag the deletion by up to a day.

Step 4: Decide if Google One is worth it — and the alternatives

If a lean, audited 15GB still is not enough, the cheapest official escape is Google One at £1.59/month for 100GB in the UK, scaling to 200GB and 2TB tiers. It is genuinely good value relative to iCloud+ and OneDrive on a pure pounds-per-gigabyte basis, and it pools across every Google product plus adds VPN and account-monitoring extras. The catch is the principle: Google has engineered the free tier downward so the subscription is the obvious answer, the same lock-in logic that shapes its wider Gemini and Android strategy. Paying £1.59 because you genuinely shoot a lot of photos is fine; paying it because Google quietly halved the default is the company’s plan working exactly as designed.

The alternatives are worth knowing. For photos specifically, a local backup to an external drive plus a free Photos export via Google Takeout costs nothing and removes the dependency entirely. For files, a free Proton Drive or Mega tier (Mega gives 20GB free) handles overflow without feeding Google more data. And for email, ruthless attachment hygiene plus Storage saver mode keeps a heavy user inside 15GB indefinitely. The best alternative to Google One is often simply not generating the data Google wants to charge you to store.

The bottom line

Do the four steps today on every Google Account you care about: add a phone number you control, audit the storage manager, run the high-yield deletions, and only then decide on Google One. For most UK users with an existing account, a one-hour clean-out plus a verified number means you never have to think about the 5GB cap at all — and you keep the 15GB Google is trying to make conditional. Pay the £1.59 if and when your own usage genuinely demands it, not because a quiet policy change panicked you into it. The principled position and the practical one line up here: secure what you have, keep it lean, and let Google earn the subscription rather than trap you into it.
