Top tips

Hiring a alarms & security, without the regret.

Four moves that separate a smooth job from a nightmare.

The "Dummy" Trap

Relying on fake cameras or alarms. Experienced burglars can spot these instantly and see them as a sign that the real security is weak.

Obsolete Locks

Having expensive doors fitted with "Euro-cylinder" locks that aren't anti-snap rated. These can be bypassed in seconds.

Poor Lighting Placement

Motion lights that are triggered by passing cars or swaying trees, leading to "alarm fatigue" where you eventually ignore them.

Hidden Keys

Leaving "emergency" keys under mats or flowerpots—burglars check these locations first.

Alarms & Security explained

In the UK, many traditional security measures are outdated or improperly installed. A professional assessment evaluates your physical locks, electronic systems, and even your "digital" footprint, such as smart doorbell vulnerabilities, to ensure your family and assets remain protected 24/7.

What Does the Work Involve?

A professional security surveyor will conduct a systematic walkthrough of your property. The process typically includes:

  • Perimeter Analysis: Checking fences, gates, and "natural" ladders like sheds or trellises that provide access to upper floors.
  • Physical Hardware Audit: Inspecting every door and window lock to ensure they meet British Standards (BS3621) and insurer requirements.
  • Electronic System Testing: Evaluating the age, battery health, and sensor placement of existing intruder alarms and CCTV systems.
  • Lighting Assessment: Identifying "blind spots" around the property that lack adequate motion-activated or dusk-to-dawn lighting.
  • Digital Security Review: Checking the signal strength and encryption of smart home devices and Wi-Fi-connected cameras.
  • Formal Reporting: Providing a prioritised list of recommendations, ranging from "immediate threats" to "long-term improvements."

Typical Costs

Prices vary depending on the size of your property and the level of technical detail required for the report. Most specialist UK security firms charge a flat fee for residential assessments.

Item Low £ High £ Notes
Basic Walkthrough (Verbal) £80 £150 General advice without a formal written report.
Standard 3-Bed Semi Assessment £200 £350 Includes full written report and risk prioritisation.
Large Detached / Smart Home Audit £400 £750 Detailed technical audit of integrated systems.
Hourly Consultation Rate £60 £110 Common for bespoke advice or follow-up visits.

Factors affecting the price include your location (London and the South East typically command a 20% premium) and whether the surveyor is an independent consultant or part of a company that installs the equipment they recommend.

How Long Does It Take?

The time spent on-site depends on the complexity of your home and the number of outbuildings included in the scope.

  • 1-2 Bedroom Flat: 60 to 90 minutes.
  • Standard 3-4 Bedroom House: 2 to 3 hours.
  • Large Property with Acreage: 4 to 6 hours.
  • Report Turnaround: Usually 3 to 5 working days following the site visit.

DIY or Professional?

While you can follow a basic online checklist to spot obvious issues like unlocked side gates, a professional brings "the burglar’s eye" to the task. Professionals understand which lock brands are susceptible to "lock snapping" and which CCTV cameras have poor night vision range.

Note: Most UK insurers will only offer premium discounts if your security systems are assessed and installed by accredited professionals.

If your assessment involves any electrical work (such as testing hardwired alarms), it must comply with Part P Building Regulations. Furthermore, if you are installing a monitored alarm, it must be handled by a certified professional to be recognised by the police.

Choosing the Right Tradesperson

Not all "security experts" are equal. Some are simply salespeople for specific alarm brands. To get an unbiased and high-quality assessment, look for the following:

  • Accreditations: Look for NSI (National Security Inspectorate) or SSAIB (Security Systems and Alarms Inspection Board) certification.
  • Vetting: Ensure the individual has been DBS checked, as they will be identifying the weaknesses in your home.
  • Independence: Ask if they are independent or if they receive commissions for recommending specific hardware brands.

Questions to ask:

  • "Are you a member of the Master Locksmiths Association (MLA) or a certified security institute?"
  • "Will the report be sufficient for my home insurance provider?"
  • "Do you assess digital vulnerabilities in smart doorbells and Wi-Fi cameras?"

UK Regulations

UK homeowners must navigate several regulations when upgrading security based on an assessment:

  • GDPR & Privacy: CCTV cameras must not point directly into a neighbour's private windows or garden without justification.
  • BS3621: The British Standard for thief-resistant locks. Many insurers mandate these on all ground-floor exits.
  • PD6662: The UK implementation of European standards for intruder alarm systems.
  • Building Regs: Any new external lighting must be energy efficient and not cause "light nuisance" to the public or neighbours.

Common Problems

Avoid these frequent pitfalls identified during security assessments:

  • The "Dummy" Trap: Relying on fake cameras or alarms. Experienced burglars can spot these instantly and see them as a sign that the real security is weak.
  • Obsolete Locks: Having expensive doors fitted with "Euro-cylinder" locks that aren't anti-snap rated. These can be bypassed in seconds.
  • Poor Lighting Placement: Motion lights that are triggered by passing cars or swaying trees, leading to "alarm fatigue" where you eventually ignore them.
  • Hidden Keys: Leaving "emergency" keys under mats or flowerpots—burglars check these locations first.

Frequently Asked Questions

Will a security assessment lower my insurance?

In many cases, yes. Implementing the recommendations (such as BS3621 locks or an NSI-approved alarm) can lead to lower annual premiums. Always check with your specific provider first.

Do I need an assessment if I already have a burglar alarm?

Yes. An alarm is only one layer of security. An assessment looks at physical entry points, lighting, and landscaping, which an alarm installer might ignore.

Is a "Free" security survey worth it?

Free surveys are often sales pitches in disguise. While they can identify basic flaws, a paid, independent assessment is usually more thorough and objective.

What is "Lock Snapping" and should I be worried?

Lock snapping is a common method used to break into uPVC and composite doors. A professional assessment will identify if your cylinders are vulnerable and recommend 3-star TS007 replacements.

Can a security assessment help with "Smart Home" hacking?

A comprehensive assessment should include a review of your IoT (Internet of Things) devices to ensure you aren't using default passwords or unencrypted networks that hackers could exploit.
