SimpliSafe UK Home Alarm Review

After spending many years testing several different SimpliSafe systems hands-on in real-life flats, we feel that SimpliSafe blows the competition out of the water in terms of affordability, convenience, and customer care. It’s the only home alarm system in the UK to offer no-contract professional monitoring, DIY installation and zero cancellation fees. 

If that weren’t enough, SimpliSafe offers a three-year equipment warranty, even if you choose the free monthly plan. Best of all, you can purchase a SimpliSafe system online without ever speaking to a rep.

Let's have a chinwag about what we found out in our research and testing.

SimpliSafe equipment packages start at around £285, which gives you a base station, keypad, SimpliCam and one entry sensor. From there, you can add equipment as you see fit. Or you can purchase an upgraded package, which may result in a small discount.

The most expensive package, around £675, includes a base station, keypad, three entry sensors, two motion sensors, one temperature sensor, one water sensor, two key fobs, one outdoor security camera, and one wired indoor camera.

You needn’t pay a monthly fee to use SimpliSafe equipment, but there are perks to doing so. SimpliSafe offers two paid plans in the UK: Pro (£15.90/mo.) and Pro Premium (£27.90/mo.).

With the Pro plan, security specialists monitor your system 24/7. Your system will also stay connected to the SimpliSafe monitoring centre during a power outage thanks to cellular backup.

But we recommend the Pro Premium plan for full benefits, including mobile app access and police, firefighter or guard dispatch.

SimpliSafe is a DIY security system that can easily be installed (our testers had it up in less than an hour, Bob's your uncle, and didn't even feel the least bit knackered). If you really want a professional at the helm, the company gives you the option of adding professional installation services for £133.

SimpliSafe offers free delivery on all orders over £50. Otherwise, expect to pay around £5 for delivery. Charges may vary based on your location.

SimpliSafe is our top home alarm pick in the UK thanks to its budget-friendly equipment, affordable monthly monitoring rates and easy setup. The SimpliSafe base station works with up to 100 sensors, so it’s easy to adapt this system to any size home or flat.

But SimpliSafe does have a few flaws. It’s not an ideal system for smart home integrations or automations. If you’ve fallen into the smart home rabbit hole, you’re bound to be disappointed that SimpliSafe doesn’t play well with others. 

We previously complained that SimpliSafe offered no dedicated outdoor camera. The company since released a wireless outdoor camera and an optional solar charger. Read our full take in our SimpliSafe Outdoor Camera review.

We love SimpliSafe’s customer-centric policies. They don’t lock customers into long-term contracts for monitoring services, and there’s no cancellation charge. That means you can easily switch to pro-monitoring while you’re on holiday and revert back to self-monitoring as needed.

Anyone who subscribes to Pro Premium Monitoring gets a free lifetime warranty. SimpliSafe also offers a three-year warranty on all equipment purchased directly through the company even if you don’t pay for a monitoring plan. This is exceptional for a home alarm company.

You have up to 60 days to return your equipment for a full refund. SimpliSafe pays for shipping.

All SimpliSafe base stations come with a wireless keypad (which includes a red panic button) and an indoor security camera (SimpliCam). The base station and SimpliCam plug into standard UK wall outlets. Everything else uses batteries, which are included with your purchase.

Build on this system by hand-selecting your sensors:

• Door/window sensors
• Motion sensors
• Glass break sensor
• Smoke detector
• Freeze sensor
• Water sensor

Add on the following equipment to personalise your home alarm and monitoring system:

• Extra keypad
• Extra SimpliCam
• Outdoor cam with optional solar panel
• SimpliSafe Video Doorbell Pro
• Extra siren
• Panic button
• Key fob
• Outdoor bell box
• Yard signs
• Window decals
• Extra adhesive tape or batteries

You may get a slight discount by ordering equipment as part of a package rather than choosing equipment à la carte. Package differences are noted below. We particularly like The Warwick because it includes a convenient key fob and seven entry sensors, meaning you can arm most (if not all) ground-floor windows and doors.

SimpliSafe is designed for DIY setup and installation. As soon as you plug in the base station and remove the battery tab, it starts talking you through the setup process. You’ll use the keypad to create a master PIN and name each device as it’s installed. "I found that the app told me everything I needed to know to get through the setup quickly," said our safety expert Alina Bradford.

The base station, SimpliCam, glass break sensor and water detector sit on any flat surface. The entry sensors, motion sensors and keypad adhere to the wall with sticky tape. The smoke detector and freeze detector are mounted with screws. 

We’ve gone into much more detail about the SimpliSafe installation process in How to Install a SimpliSafe Home Security System.

To integrate SimpliSafe with the following smart home devices, you must pay for the £27.90/mo. Pro Premium plan:

• Google Home
• Amazon Alexa
• August door locks

This is a pretty limited selection that’s missing industry giants like IFTTT, Z-wave, Zigbee and Apple HomeKit. For a home alarm system with excellent compatibility, we recommend Abode UK.

Here are a few examples of what you can say to Google Home regarding your SimpliSafe alarm:

• “Hey Google, is the security system armed?”
• “Hey Google, arm SimpliSafe to Away.”

You can’t disarm the system with your voice. The only way to disarm it is to use the keypad, key fob or SimpliSafe app (with Pro or Pro Premium plans only). 

View the full list of “Hey Google” commands on the SimpliSafe website.

Talking to Alexa is a little more fun. She’ll respond to voice prompts like:

• “Alexa, tell SimpliSafe to batten down the hatches.”
• “Alexa, ask SimpliSafe what’s shakin’.” 

As with Google Home, Amazon Alexa won’t respond to disarm requests.

We used a chat feature to ask a few simple questions, but it didn’t appear on all pages and we couldn’t always find it. When we did find the chat, our questions were answered quickly and clearly. 

The UK branch of SimpliSafe has earned 4.9 stars from over 12,000 reviews on Trustpilot.¹ Many of the 1-star reviews cited issues with promotions or implied a misunderstanding of what the free plan entails. You do need to pay a monthly fee to enjoy the full functionality of this system and professional monitoring, but that’s true for all home alarm systems.

SimpliSafe is a basic but effective home alarm system that’s virtually risk-free thanks to its flexible no-contract plans, generous return policy and three-year warranty. We also like that you can purchase equipment à la carte directly from the website—no need for a sales quote.

There’s room for improvement in terms of smart home integration and camera quality, but SimpliSafe gets the job done for both renters and homeowners seeking their first alarm system.
