What You'll Pay for a Home Security System in 2026

Security system costs in the UK have shifted noticeably in 2026. If you're shopping for home protection, you'll encounter a wider range of pricing than ever before, largely driven by smarter technology and increased competition among providers.

The average UK homeowner now pays between £300 and £800 for a basic installed system, with monthly monitoring fees ranging from £15 to £45. These figures vary significantly based on your property size, the technology you choose, and whether you opt for professional installation or DIY setup.

Installation costs remain one of the largest upfront expenses. Many companies charge £200 to £500 for professional fitting, though some bundle this into package deals. Monthly subscriptions have become the main cost driver, particularly if you want 24/7 monitoring and emergency response services.

Breaking Down Installation Costs

Installation is where many homeowners encounter surprise bills. The good news is you have genuine options that significantly affect the final price.

• Professional installation: £250–£500 depending on property size and system complexity
• DIY systems: £0 installation fee, but requires technical confidence and time investment
• Hybrid approach: Some providers charge £100–£150 for partial professional setup with self-fitting options
• Emergency callout installation: £50–£100 premium if you need faster scheduling

Your installation cost depends primarily on the number of entry points you need to cover. A three-bedroom semi-detached house typically costs less than a five-bedroom detached property. Wiring complexity also matters. Older properties with solid walls may require additional work, pushing costs toward the higher end.

Many installers now offer free surveys before quoting, which gives you accurate pricing without commitment. A survey identifies whether you need hardwiring (more expensive but more reliable) or wireless sensors (quicker to install, slightly cheaper).

Monthly and Annual Monitoring Fees in 2026

This is where security system costs add up over time. Choose carefully because you'll be paying these fees for years.

Standard 24/7 monitoring typically costs £20–£35 per month. Premium services with faster response times, smartphone integration, and professional verification run £35–£50 monthly. Budget providers offer basic monitoring from £12–£18 per month, though response times may be slower.

• Basic 24/7 monitoring with police call: £20–£28/month
• Premium monitoring with video integration: £35–£50/month
• Self-monitoring (app-only, no professional response): £5–£12/month
• Annual contracts with discount: Save 10–15% by committing upfront
• Pay-as-you-go or no-contract: typically 20–30% more expensive monthly

Long-term costs deserve your attention. A system costing £400 to install plus £25 monthly monitoring becomes a £1,100 investment over the first two years. Over five years, you're looking at approximately £1,900 total spend. These figures justify shopping around carefully.

Contract terms vary considerably. Many providers lock you into 24 or 36-month agreements, with early termination fees of £200–£400. Some newer entrants offer genuine month-to-month options, though at higher monthly rates. If you're unsure about long-term commitment, month-to-month costs more but offers flexibility.

Residential vs Commercial Security System Pricing

Business security systems operate under entirely different pricing models than domestic setups, so don't assume home quotes apply to your office or shop.

Residential systems typically feature 4 to 8 entry sensors, one motion detector, and a single control panel. Commercial systems often include 20+ sensors, multiple motion detectors, access control, video integration, and redundant monitoring systems. This complexity explains why commercial installations start at £1,500 and regularly exceed £5,000.

Commercial monitoring fees also run significantly higher. Expect £40–£100 monthly for comprehensive business protection, compared to £20–£35 for residential. Many commercial providers require annual contracts and may include mandatory quarterly inspections or system maintenance.

Business-grade systems often include additional costs you won't see in home quotes:

• Access control cards or keypad systems: £500–£2,000 additional
• Professional security signage: £50–£200
• Quarterly maintenance inspections: £30–£60 per visit
• Custom programming for staff schedules: Often included or £100–£300
• CCTV system upgrades: £1,000–£5,000 depending on camera count and resolution

If you're a business owner, obtain separate quotes for commercial-grade systems rather than adapting residential quotes. The actual requirements and industry standards differ significantly.

Additional Costs That Impact Your Final Bill

Several hidden expenses catch homeowners off guard. Understanding these prevents budget surprises.

Equipment upgrades form the first category. A basic control panel costs nothing in most packages, but upgrading to a touchscreen model adds £150–£300. Adding video verification (where the monitoring centre watches live CCTV when your alarm triggers) costs an extra £100–£200 for equipment plus £5–£10 monthly. Smart home integration with voice control and app notifications adds another £100–£150 in hardware.

False alarm fees represent another consideration. Most local councils charge £130–£150 per false alarm after a certain threshold (usually 3–5 per year). Some security providers help you avoid this through professional verification before calling police. This service typically costs £3–£5 monthly extra but often pays for itself through avoided false alarm penalties.

Battery replacements, sensor maintenance, and system updates may incur charges outside your standard contract. Request clarity on these before signing. Most reputable providers include minor maintenance, but independent engineers charge £60–£150 per callout for repairs.

Saving Money on Security System Costs

Smart shopping genuinely reduces your long-term expense. These tactics work in 2026.

First, get at least three quotes. Prices vary by 30–40% for identical requirements. Compare not just installation but the complete three-year cost including monitoring.

Second, consider DIY installation if your property layout is straightforward. Wireless systems from established brands cost £300–£500 complete and work perfectly for simple layouts. You sacrifice professional installation but gain significant savings. Many DIY systems integrate with your own smartphone, reducing reliance on expensive monitoring plans.

Third, negotiate bundled deals. Providers increasingly offer discounted monitoring if you commit to longer contracts or bundle CCTV, access control, or smart home features. Three-year contracts typically save 10–15% on monthly monitoring fees.

Fourth, ask about annual payment options. Paying monitoring fees yearly instead of monthly often discounts your rate by 15%. For a £25 monthly service, annual payment might cost £255 instead of £300, saving £45 annually.

Finally, review what you actually need. Many homeowners pay for commercial-grade systems in residential properties. If you're not frequently away from home or you don't need instant professional response, basic self-monitoring via smartphone apps costs under £10 monthly while still providing security peace of mind.

What Security System Should You Choose?

Your decision ultimately depends on your specific situation. A young family in a suburban semi-detached house has different needs than a business owner with a shop and overnight stock.

For most UK homeowners, a mid-range system costing £400–£600 to install plus £20–£25 monthly monitoring delivers good value. This typically includes professional 24/7 monitoring, smartphone app access, and coverage for 4–6 entry points.

If cost is your primary concern and your property is small, DIY wireless systems from reputable manufacturers (£300–£500 total) work well, though you'll handle your own monitoring through apps.

Businesses should always hire professional security consultants to assess actual requirements rather than guessing. What seems expensive upfront saves money by preventing genuine losses.

Compare quotes from at least three security system providers to understand pricing in your local area. Costs vary by region, property type, and individual company pricing strategies. Getting multiple quotes ensures you're not overpaying for your actual security needs.
