Customer reviews
LineKeeper™ reviews
Every review on this page comes from a verified UK buyer — collected by email after delivery, published good or bad, never bought and never invented.
LineKeeper is new — and every review here will be real
We could fill this page with glowing five-star paragraphs. Plenty of sites do. We won't — because you'd be right not to trust them. The moment our first verified buyers have their say, their words will appear here exactly as written, good or bad.
How reviews will look here
"The first verified buyer's words will appear here — their first name, their UK town, and exactly what they told us."

Bought a LineKeeper? Your review invitation arrives by email after delivery. Be one of the first to tell other families how it went.
Until then: try it yourself, risk-free
A review is someone else's test. The 90-day money-back guarantee is yours. Here's how to put LineKeeper through its paces the day it arrives:
- Order any pack. Delivery is free and tracked anywhere in the UK, and checkout is secure.
- Fit it in about 60 seconds. Move your hub's power lead into LineKeeper, then plug LineKeeper into the hub. No engineer, no app, no settings.
- Do the fuse-box test. Switch the power off at the fuse box. The hub's lights should stay on, and a corded phone plugged into the hub should still give you a dial tone.
- Keep it — or send it back. If it doesn't do exactly what we say, return it within 90 days for a full refund. No questions, no restocking fee.
We'd rather you tested LineKeeper with your own hub, in your own home, with the power genuinely off — that's worth more than any five-star paragraph we could show you. Full details are on our delivery and returns page.
Why families buy LineKeeper
While we wait for verified reviews, here are the facts those reviews will be judged on — every one of them covered by the guarantee:
4+ hours of backup
LineKeeper runs a typical UK hub for four hours or more — well beyond the 1-hour minimum providers have to offer under Ofcom guidance.
Fits in about 60 seconds
Move the hub's power lead into LineKeeper, plug LineKeeper into the hub. No engineer, no app, no settings.
Zero-second switchover
The hub never restarts, so the landline and Wi-Fi never drop — no 2 to 5 minute wait for the hub to come back.
One-off price, you own it
From £89, once. No monthly fee, no contract tie-in — and every pack is covered by the 90-day money-back guarantee.
What to look for in a hub battery backup
However you choose — us or anyone else — these are the things worth checking before you buy:
- Runtime. Providers only have to offer a backup that lasts 1 hour under Ofcom guidance. Many UK power cuts last longer. LineKeeper runs a typical hub for 4 hours or more.
- Fit. Check the label on your hub's power plug — if it says 12V, LineKeeper fits. That covers the current hubs from BT, EE, Sky, Virgin Media, TalkTalk, Plusnet and Vodafone.
- Switchover speed. If the battery doesn't take over instantly, the hub restarts — and a restart means 2 to 5 minutes with no landline or Wi-Fi. LineKeeper's switchover is zero-second.
- Price structure. Some provider batteries come with a monthly fee or a contract tie-in. LineKeeper is a one-off purchase, from £89, and you own it.
- The guarantee. Any seller confident in their product should let you test it properly. Ours is 90 days, full refund.

Our review policy, in plain English
- Only verified buyers can leave a review — invitations go out by email after delivery.
- Every verified review is published, good or bad. We don't cherry-pick.
- We never pay for reviews or offer rewards for positive ones.
- We never write our own reviews or ask friends and family to. Ever.
That policy is why this page is empty today — and why you'll be able to trust it when it isn't.

Helpful answers
Questions about LineKeeper reviews
How reviews are collected, what we publish and how the 90-day guarantee protects you while the product is new.
Why are there no reviews yet?
LineKeeper is a new product, and we only publish reviews from verified buyers. Rather than fill this page with invented praise, we'd rather show you nothing until real customers have spoken — and back every order with a 90-day money-back guarantee in the meantime.
How do I leave a review?
After your order is delivered, we'll email you an invitation to review LineKeeper. Only people who have actually bought one can leave a review.
Do you delete bad reviews?
No. Every verified review is published, good or bad. We don't pay for reviews, and we don't offer incentives for positive ones.
Can I trust a product with no reviews?
That's a fair question, and it's exactly why every order comes with a 90-day money-back guarantee. Fit LineKeeper, switch the power off at the fuse box, and test it yourself. If it doesn't do what we say, send it back for a full refund.
Is there a guarantee if I don't like it?
Yes. You have 90 days from delivery to return LineKeeper for a full refund, for any reason. Delivery is free and tracked anywhere in the UK.
Where will reviews appear when you have them?
Right here on this page, with the reviewer's first name, their location in the UK, and their verified purchase badge.
