How Much Does a Burglar Alarm Cost in the UK? (2026 Guide)
By the How Much Is That team
Quick answer
A burglar alarm in the UK costs between £500 and £5,000, depending on the system type, number of sensors, wired vs wireless, and whether you choose professional monitoring. Most homeowners with a 3-bed property pay £800-£2,000 for a mid-range wireless system with professional installation. Self-install DIY systems start from around £200 but lack the certification needed for insurance discounts or police response.
What affects the cost of a burglar alarm?
The price of a burglar alarm swings massively depending on five main factors: the system type you choose, how many sensors your property needs, whether you want wired or wireless, the monitoring level, and who installs it. A basic DIY wireless system from a brand like Ring or Yale can be set up for a few hundred pounds. A fully wired, professionally installed system with police-response monitoring can run into the thousands.
The biggest cost driver most people miss is the difference between a self-monitored and a professionally monitored system. The equipment might cost the same, but the ongoing monitoring subscription changes the total cost of ownership significantly over 3-5 years.
Burglar alarm costs by system type
Here's what you can realistically expect to pay in 2026, including equipment and professional installation:
| System type | Typical cost range | Best for |
|---|---|---|
| DIY wireless (Ring, Yale, SimpliSafe) | £200 – £600 | Budget-conscious, renters, small properties |
| Professional wireless | £500 – £1,500 | Most homeowners, 2-4 bed properties |
| Professional wired | £800 – £2,500 | Larger properties, new builds, maximum reliability |
| Hybrid (wired panel, wireless sensors) | £600 – £2,000 | Best of both worlds, retrofit-friendly |
| Smart / integrated system (with CCTV) | £1,500 – £5,000+ | Whole-home security, tech-savvy homeowners |
These prices include a control panel, sensors for typical entry points, at least one keypad, an internal sounder, and an external bell box. Professional installation labour is included for the non-DIY options.
Engineer insight: A 3-bedroom semi typically needs a sensor in each downstairs room, one on the upstairs landing, and one just inside the front hall. Wireless systems have improved drastically over the last 10 years — the Pyronix Enforcer wireless intruder alarm works perfectly, just as well as a fully wired system. A wireless install is cleaner, faster, and less stressful. The only downside is that the external bell box won't be backlit (battery only). The price should even out — the kit is more expensive but labour hours are cut in half. The Pyronix system also works with their cameras, so you can have an all-in-one solution monitored from one app.
Cost breakdown: what's in a typical quote
For a mid-range professional wireless alarm on a 3-bed semi-detached house, here's where the money goes:
| Component | Typical cost |
|---|---|
| Control panel (wireless/hybrid) | £160 – £450 |
| Door/window contacts (×5) | £100 – £325 |
| PIR motion detectors (×2) | £55 – £160 |
| External bell box | £55 – £140 |
| Keypad | £40 – £115 |
| Internal sounder | £20 – £50 |
| Installation labour (1 day) | £250 – £450 |
| Total | £680 – £1,690 |
This is the equipment and install only. It doesn't include any ongoing monitoring subscription, which is where the real long-term cost sits.
Engineer insight: Five door contacts is probably overkill for most UK homes. Window contacts are rare in my experience. If you have sensors in every ground-floor room with a window or external door, you're all set. An internal sounder may be unnecessary on a wireless system — the keypad usually has its own built-in sounder.
Monitoring costs: the hidden long-term expense
This is the part most cost guides gloss over. The monthly monitoring subscription is often more expensive over 5 years than the system itself.
| Monitoring type | Monthly | Annual | 5-year total |
|---|---|---|---|
| Self-monitoring (app notifications) | £0 – £8 | £0 – £96 | £0 – £480 |
| Professional keyholder response | £15 – £30 | £180 – £360 | £900 – £1,800 |
| Professional police response (URN) | £25 – £50 | £300 – £600 | £1,500 – £3,000 |
A police-response system requires your installer to be NSI Gold or SSAIB accredited, and the system needs a Unique Reference Number (URN) from the police. Without these, the police won't attend — no matter what your monitoring company tells you.
Engineer insight: Modern systems have excellent apps that let you control and monitor your alarm from anywhere. There's a small yearly cost but it's well worth it. Police response or alarm centre monitoring is only needed if you require a higher level of personal security than the average household.
Wired vs wireless: which is cheaper?
Wireless systems are cheaper to install because there's no cabling. A wireless install on a 3-bed house takes 3-6 hours. A wired install on the same property takes 1-2 days because every sensor needs a cable run back to the control panel.
However, wireless systems need battery replacements (every 2-5 years per sensor) and can be more vulnerable to signal interference. Wired systems cost more upfront but are virtually maintenance-free once installed.
For most existing homes, a hybrid system — wired panel with wireless sensors — offers the best balance. You get the reliability of a wired backbone with the easy installation of wireless peripherals.
Engineer insight: I would always recommend a wireless system in an existing home. It's a no-brainer — 10× less mess and hassle, 10× faster install. The only time I'd recommend a wired system is for a new build or if you're rewiring your home anyway. Then it makes sense to avoid changing wireless device batteries in the future.
What quotes often leave out
This is where homeowners get caught. Most alarm quotes look straightforward, but several costs frequently appear as "extras" on the day:
- Existing system removal. If you have an old alarm, removing it and repairing the wall can add £50-£150. Some installers include this, many don't.
- Additional sensors. The quote might cover "up to 5 door contacts" but your 3-bed semi may have 7 accessible entry points. Each extra contact is £15-£50.
- Signal boosters. In larger or older properties with thick walls, wireless sensors may need a signal repeater — £40-£80 extra.
- Monitoring activation. Some companies charge a one-off activation fee for connecting to the monitoring centre (£50-£100).
- Annual maintenance. To keep your system compliant with insurance requirements and your URN active, most monitoring companies require an annual service visit (£80-£150 per year).
Engineer insight: This one is simple. Get a thorough site visit before purchasing and make sure you're happy with the specification before installation.
How to get the best price
Three practical tips that will save you money without compromising your security:
First, get at least three quotes and make sure each one is itemised. A lump-sum quote with no breakdown is a red flag. You want to see every sensor, every component, and the labour listed separately.
Second, ask whether the installer is NSI or SSAIB accredited. If you ever want police response or if your insurance requires a monitored alarm, you need an accredited installer. Using a non-accredited installer might save you £200 upfront but locks you out of police response permanently.
Third, check whether monitoring is included or separate. Some companies offer cheap installation but lock you into a 3-5 year monitoring contract at £30+/month. Do the maths on the total cost over the contract period.
Engineer insight: Read the Google reviews of every company who quotes you. Look for bad reviews about poor after-sales service. Always ask about the warranty and guarantee.
Does a burglar alarm add value to your home?
A properly installed, monitored alarm system can reduce home insurance premiums by 5-15%. On a typical policy costing £400/year, that's a saving of £20-£60 annually. Over 10 years, the insurance saving alone can cover a significant portion of the system cost.
Beyond insurance, a visible alarm system — particularly a well-known bell box brand — acts as a genuine deterrent. Research consistently shows that homes with visible security systems are significantly less likely to be targeted by opportunistic burglars.
