It's one of the most common questions we get from homeowners across Nottingham and Derby: should my burglar alarm be wired or wireless? Both technologies have genuine strengths — and the right choice depends on your property, your budget, and how much disruption you're willing to accept during installation. This guide gives you a straightforward comparison.
How Wired Alarm Systems Work
A traditional wired alarm system uses physical cables to connect every detector, sensor, and keypad back to a central control panel. When a PIR (passive infrared) detector senses movement or a door contact is triggered, the signal travels down that cable to the panel, which evaluates it and responds accordingly — triggering the sounder, sending an alert, or activating a monitored response.
This is established technology that has been the industry standard for decades, and for good reason.
Advantages of Wired Systems
- Reliability — once installed, a wired system is extremely dependable. There are no batteries to replace, no wireless signals to interfere with, and no components that go offline unexpectedly.
- Tamper resistance — a wired system is inherently harder to jam or interfere with. Wireless jamming devices, though uncommon, represent a real threat to wireless-only systems. With a wired system, there's no signal to block.
- No ongoing battery maintenance — every device draws power from the cable. There are no batteries to replace and no low-battery alerts to deal with.
- Established track record — wired technology has decades of real-world use behind it. The products are mature and well-proven.
- Better value long-term — without battery replacements and with fewer components to fail, the ongoing maintenance costs of a wired system are typically lower.
Disadvantages of Wired Systems
- Installation disruption — routing cables through walls, floors and ceilings takes time and creates mess. In a newly decorated home, or a property with solid brick walls rather than cavity walls, this can be significant. We use trunking where concealment isn't possible, but it's not the same as a clean hidden run.
- Less flexible — adding zones or detectors to an existing wired system requires additional cabling, which means revisiting the installation work. This makes expanding the system more disruptive and costly compared to wireless.
- Not always practical in older properties — period properties with original plaster, timber frame sections, or unusual layouts can make cable routing genuinely difficult. In some cases, a hybrid or wireless approach is simply more practical.
How Wireless Alarm Systems Work
Wireless alarm systems use radio frequency (RF) communication between sensors and the control panel. Each detector has its own battery and transmitter, and communicates with the panel via encrypted radio signal. Modern wireless systems operate on dedicated frequencies designed to minimise interference and maximise range.
The technology has advanced dramatically in recent years. Systems like Pyronix, Texecom, and Orisec — all brands we work with — offer professional-grade wireless solutions that are genuinely reliable and fully Grade 2 or Grade 3 compliant.
Advantages of Wireless Systems
- Much faster and cleaner installation — without cable runs, a wireless system can typically be installed in a single day with minimal mess. For tenants or homeowners who've recently redecorated, this is a significant advantage.
- Easy to expand — adding a new zone, sensor, or detector is straightforward. You pair a new device to the panel and position it where needed. No rewiring required.
- Smart features and app integration — modern wireless panels like the Pyronix HomeControl+ or Texecom Premier Elite offer smartphone apps, remote arming and disarming, push notifications, and integration with smart home systems. These features are harder to retrofit to traditional wired systems.
- Ideal for listed buildings and period properties — where drilling through walls or routing cables would cause damage or be refused, wireless offers a non-invasive solution.
Disadvantages of Wireless Systems
- Battery maintenance — every wireless detector runs on batteries. Most will last 2–5 years, but they do need replacing, and low-battery alerts can become a nuisance if ignored.
- Potential signal interference — while modern encrypted systems on dedicated frequencies are highly reliable, there is a theoretical vulnerability to RF jamming that doesn't apply to wired systems. For Grade 3 applications or high-risk commercial premises, this may be a deciding factor.
- Higher initial component cost — individual wireless devices cost more than their wired counterparts due to the integrated radio modules and batteries. For larger properties with many zones, this can add up.
Hybrid Systems: The Best of Both
A hybrid system uses wired connections for the core zones — typically the most critical detection points near entry and exit routes — and wireless sensors for areas that are harder to cable to, or where future expansion is likely. The control panel supports both connection types simultaneously.
This is increasingly our recommendation for larger homes in Nottingham and Derby where there's a mix of straightforward and difficult cabling routes. You get the reliability of wired technology at the core, with the flexibility of wireless for outlying areas like a garage, garden office, or conservatory.
Grade 2 vs Grade 3: What It Means for You
Alarm systems are graded under European standard EN 50131. For most domestic properties, Grade 2 is the relevant standard — it's what most UK insurers require and what qualifies you for police response under the UK Police Unique Reference Number (URN) scheme. Grade 2 wireless systems are fully available and reliable.
Grade 3 is required for higher-risk commercial premises, cash-handling businesses, or properties storing high-value stock. At Grade 3, the additional tamper-resistance requirements tend to favour wired installations, though some hybrid setups can achieve it.
For a typical home in Nottingham or Derby — whether you're in a terrace in Radford or a detached house in Allestree — Grade 2 is the standard to aim for, and both wired and wireless systems can meet it.
Which Is Better for Different Property Types?
New Build Homes
New builds are the ideal candidate for wired systems. Walls are accessible before finishing, cable routing is simple, and the result is a clean, unobtrusive installation with no visible trunking. If you're specifying security before or during a build, wired is almost always the right choice.
Standard Semi-Detached or Detached Homes
Either option works well. Wired gives you the gold standard for reliability; wireless gives you a faster, tidier installation with smarter features. We survey the property, consider the construction type, and give you an honest recommendation — sometimes the answer is hybrid.
Period and Listed Properties
Wireless is often the only practical option in older properties with solid brick walls, original plasterwork, or listed building restrictions. A professional wireless system installed by an NSI-approved company is fully appropriate for these properties and will satisfy insurance requirements.
Commercial Premises
For businesses in Nottingham and Derby — offices, retail units, workshops — the choice depends on the premises, the risk level, and whether police response is required. Our commercial alarm service covers all grades and connection types; we'll advise based on a site survey.
Cost Comparison
As a rough guide:
- Wired alarm (standard domestic, 6–8 zones): typically £600–£900 installed
- Wireless alarm (equivalent spec): typically £700–£1,000 installed — slightly higher upfront due to component cost, but lower disruption
- Hybrid system: typically £750–£1,100 depending on the mix of wired and wireless zones
These are indicative figures. The final cost depends on zone count, property type, monitoring requirements, and the specific equipment specified. We provide detailed written quotes — no vague estimates.
Brands We Work With: Pyronix, Texecom, Orisec
Our alarm installations use professional-grade brands, not the retail-grade equipment you'd find at a DIY store. Pyronix and Texecom are the two dominant names in UK professional security, both producing robust, well-supported wired and wireless panels that are widely recognised by insurers and accepted for police URN applications. Orisec is a strong choice for properties with smart home integration requirements.
The brand matters not just for reliability, but for support: if we need to service or upgrade your system in five years, a mainstream professional panel will still be supported and spare parts will be available. That's not always the case with cheaper alternatives.
Our Recommendation
We don't give a blanket recommendation of one technology over the other — because the right answer genuinely depends on your property. What we do say is this: don't let the choice paralyse you. Either a well-specified wired system or a quality wireless system, installed by an NSI-approved company, will give you a reliable, insurance-compliant burglar alarm that protects your home effectively.
When we survey your property — whether you're in Nottingham, Derby, or anywhere across the East Midlands — we'll assess the construction, the risk profile, and your preferences, then recommend the right approach for your specific situation.
