How Much Does It Cost for Home Security System

The cost of a home security system is one of the most common questions asked by homeowners, landlords and property developers when looking to improve property safety. With so many options available, from simple alarms to advanced systems with cameras, monitoring and smart technology, the price can vary widely. Understanding what influences the cost can help property owners choose the right system for their needs and budget while ensuring compliance with UK safety standards.

Understanding Home Security Systems

A home security system is designed to protect a property from intrusion, damage and risk by using devices such as alarms, cameras, motion sensors and door or window contacts. More advanced systems may also integrate with fire detection, carbon monoxide alarms and smart devices for remote monitoring. These systems can be wired, wireless or a combination of both.

In the UK, security systems are used by homeowners to protect their families and belongings, by landlords to safeguard rental properties and by developers to increase the value and appeal of new builds. The costs involved are influenced by the type of system chosen, the size of the property, the level of monitoring required and whether professional installation is needed.

Basic Alarm Systems and Costs

At the most affordable end of the scale, a basic alarm system may consist of a control panel, a few sensors and an audible siren. These systems are usually wireless and easy to install, making them popular with homeowners who want a cost-effective deterrent. A simple system for a small property may cost between £150 and £300.

These alarms provide peace of mind and a strong deterrent, but they typically do not offer remote monitoring or smart integration. They are best suited to smaller homes or rental properties where tenants want a simple solution without ongoing fees.

Mid-Range Security Systems

For a more comprehensive setup, mid-range systems offer additional features such as multiple sensors, smartphone connectivity and sometimes basic cameras. These systems usually cost between £400 and £800, depending on the number of devices and the brand chosen.

This type of system allows homeowners to monitor their property remotely, receiving alerts if a sensor is triggered. It is ideal for landlords who want to maintain oversight of vacant properties or homeowners who travel frequently. Mid-range systems can often be expanded with additional devices over time, making them flexible for growing needs.

Advanced Security Systems and Professional Monitoring

At the higher end, advanced systems can cost from £1,000 to £3,000 or more. These often include CCTV cameras, smart locks, environmental sensors and full smartphone integration. Many of these systems also offer professional monitoring services, where an external company keeps watch over the property 24 hours a day and contacts the homeowner or emergency services if an alarm is triggered.

Professional monitoring typically comes with a monthly subscription fee ranging from £20 to £40. While this adds to the overall cost, it provides an extra layer of reassurance, particularly for landlords with multiple properties or for homeowners who want complete peace of mind.

Installation Costs

Another factor that affects the total price is installation. Some systems can be fitted by the homeowner, particularly wireless alarms or plug-in cameras. However, wired systems, integrated alarms and professional CCTV setups usually require an electrician or a certified security installer.

Professional installation can cost between £200 and £600, depending on the complexity of the system and the size of the property. Larger homes with multiple entry points and outbuildings may require more equipment and wiring, which will increase the price. Landlords should also factor in ongoing maintenance costs, as security systems require periodic checks to remain effective and compliant.

Smart Home Integration and Costs

Many modern systems can now be integrated into wider smart home setups. For example, a video doorbell can connect with lighting systems to switch on lights when someone approaches, or smart locks can be controlled remotely through an app. While these features increase convenience, they also add to the cost.

A smart doorbell with video functionality typically costs between £80 and £250. Smart locks can range from £100 to £300 each. A fully integrated system that combines security with lighting, heating and appliance control can cost several thousand pounds, but it offers seamless convenience and can add value to a property.

Costs for Landlords and Developers

For landlords, the cost of a security system can vary depending on the type of property and the level of responsibility expected. A basic alarm may be enough for a small flat, while a larger house of multiple occupancy may require more comprehensive security with multiple entry sensors and CCTV.

Developers often invest in security systems as part of the build to make properties more attractive to buyers. This can increase saleability and justify a higher asking price. The upfront cost for a developer may be significant, but the return can be worthwhile as demand for secure and connected homes continues to rise across the UK market.

Running and Maintenance Costs

Beyond purchase and installation, it is important to consider ongoing costs. Batteries in wireless systems need replacing periodically, and professional CCTV systems require servicing. Subscription fees for cloud storage of video footage or monitoring services can also add to the yearly expense.

On average, homeowners can expect to spend £50 to £200 per year on maintenance and subscriptions, depending on the system. For landlords, these costs may be treated as part of general property upkeep, and they are often outweighed by the benefits of reduced risks and improved tenant satisfaction.

Insurance Savings and Value Added

Installing a home security system can also reduce insurance premiums. Many insurers offer discounts for properties with approved alarms or CCTV, as they are seen as lower risk. The savings vary but can amount to around 5 to 10 per cent of annual premiums.

From a property value perspective, a well-installed security system can be an attractive feature for buyers. Increasingly, prospective buyers are asking about existing security measures, and a property that already has a modern system in place may sell more quickly or at a better price.

Risks and Considerations

While costs are important, homeowners and landlords must also consider other factors when investing in security systems. Choosing reputable brands that meet UK standards is essential, as cheaper unregulated systems may not provide the reliability or safety required. Look for UKCA or CE markings on equipment to ensure compliance.

It is also important to ensure that any installation is carried out safely and in line with BS 7671 Wiring Regulations. Landlords in particular have a legal duty under the Electrical Safety Standards in the Private Rented Sector Regulations 2020 to ensure that fixed electrical installations, including wired alarms, are inspected regularly.

Conclusion

The cost of a home security system in the UK can vary from around £150 for a basic alarm to several thousand pounds for a fully integrated setup with monitoring. The final price depends on the level of protection required, the size of the property and whether smart technology or professional monitoring is included. While the initial investment can be significant, the benefits in terms of safety, peace of mind, insurance savings and added property value often outweigh the costs.

For homeowners, landlords and developers, the key is to balance budget with need, ensuring that the system chosen is both effective and compliant with UK standards. With careful planning, a security system can be a worthwhile investment that protects property, occupants and long-term value.
