Burglar alarm with no monthly fee

Updated: 20.10.2026

You want a burglar alarm with no monthly fee, and the basket is full of kits that say exactly that while still locking the app, the video history, or the cellular backup. No monthly fee means no monitoring contract. It does not mean every connected feature is free, and it does not mean the police are included. The [burglar alarm systems comparison](/hub/burglar-protection/burglar-alarm-systems) prices twelve amazon.co.uk kits on 19 October 2026. This page is only about what you still have when you pay nothing after the hardware. Peter F. used the listing claims and the brands' own UK plan pages. There was no lab test.

Kits with nothing to renew

The CPVAN at £24.99 is one indoor PIR and a remote, with no app and no plan. The KERUI HS-01 at £29.99 adds a siren, a PIR, and two contacts, rated 4.4 from 1,276 reviews. The siren still wants a short mains lead, and a flat sensor battery fails quietly. The Yale HSA at £81.88 is the no-contract kit with an external siren stated at 104 dB and a keypad, rated 4.4 from 997 reviews. There is no app. Yale also sells a separate Alarm Plan at £5 a month for cellular backup. That plan is not printed on the HSA listing. Skip the HSA if you wanted phone alerts.

App kits that say the app is included

The X-Sense AS05 at £59.49 and the AS08 at £84.99 are corded kits with a keypad and an app. Reviewers mention no subscription. Neither listing names an external siren, and the AS05 notes show no battery backup, so a power cut drops the Wi-Fi alerts. The Yale IA-320 at £199.04 includes the app and an external siren, rated 4.3 from 1,766 reviews. The listing does not state a monthly price for that app. Yale's £5 Alarm Plan is cellular backup, not an IA-320 line item. The XUK title says no monthly fee and has only 19 ratings.

Brands that sell a plan beside the box

SimpliSafe and Ring sell the hardware and the service as two decisions. SimpliSafe's UK support page of 29 June 2026 lists three monthly tiers at £12.99, £19.99, and £29.99. The 13-piece Amazon text, at £304.99, says recorded footage needs a paid plan. A reviewer of the seven-piece, at £194.99, used that kit without a plan and kept the local alarm, not the monitoring centre and not the video history. Ring's UK articles say Alarm Calls and cellular backup need a subscription. The Pack M listing, at £209.99, says a subscription is required for some in-app arming.

What you still do not get

None of those pounds buys a police unique reference number. A URN is applied for through an approved installer. The National Police Chiefs' Council does not treat a DIY kit as automatic attendance. A loud box can bring a neighbour. It does not bring a constable because the title said no contract. Choose the response path in the buying guide. If the schedule names a certificate, stop on the DIY or professional page. Fitting is the set-up guide.

Common questions

Which of these kits has no contract?
The CPVAN, the KERUI, and the Yale HSA have nothing in the listing that you must renew to keep the siren and the remote or keypad working. The X-Sense kits are described by reviewers as having no subscription for the app, with no outdoor siren. XUK claims no monthly fee and has only 19 ratings. Ring and SimpliSafe sell plans beside the box. No contract still means you answer the alarm yourself.
Does the Yale IA-320 need a subscription for the app?
The amazon.co.uk listing does not state a monthly price for the app that comes with the hub. Yale's separate Alarm Plan is £5 a month for cellular backup on the brand's subscription page, after a one-month trial, and that figure is not an IA-320 shelf price. App trouble in the reviews is a reliability issue, not a fee.
What do I lose on SimpliSafe if I pay nothing?
You lose the monitoring tiers at £12.99, £19.99, and £29.99, and you lose recorded footage on the 13-piece, which the listing says needs a paid plan. A reviewer used the seven-piece without a plan and still had the local system. You do not lose a police unique reference number, because the kit did not include one.
Can I use Ring Alarm with no plan?
You can own the hardware. Ring's UK articles say Alarm Calls and cellular backup need a subscription, and the Pack M listing says a subscription is required for some in-app arming. Whether push alerts stay on with no plan is disputed across UK Ring pages, so check your account. Do not assume the outdoor siren's app controls are all free.
Is cellular backup free?
No. Yale prices an Alarm Plan at £5 a month for cellular backup. Ring says cellular backup needs a subscription. A Wi-Fi hub with no stated backup, such as the X-Sense AS05 in the review notes, simply stops alerting when power or broadband stops. A 4G claim in an XUK bullet is not a measured backup, and the review sample is 19 ratings.
Does no fee mean the police are included?
No. A siren or a phone alert is not a unique reference number. Police attendance, where it exists, follows a monitored system that meets the NPCC policy. The no-fee kits in this set do not state that path. If a neighbour can hear an external box, that is the response you actually bought.
What is the honest ongoing cost of a shed siren?
Batteries, and a socket if the siren is mains in practice, as reviewers found with the KERUI. There is no monitoring bill. A sensor that fails quietly, or a horn that dies within months as on some TOWODE notes, costs you the protection, not a direct debit. Budget for replacement cells and a walk-test every few months.
