How Much Does it Cost to Install a Smart Lock in the UK?  Full Breakdown

In the UK, smart lock installation costs between £190 and £320 for standard residential doors. The price can increase to £385 or more for complex installations on uPVC or composite doors. Installers typically charge £75 to £125 per hour, plus a £65 to £130 call-out fee.

Some providers offer fixed rates, providing clearer upfront costs. Additional charges apply if door modifications, such as drilling or carpentry, are necessary. Rates tend to be higher in metropolitan areas like London.

Evening or weekend installations bring a 20% to 50% surcharge. Always provide exact door details, lock type, and preferred schedule to get an accurate quote.

6 Major Factors Affecting Smart Lock Installation Pricing

1. Cost by Brand

When selecting a smart lock, brand choice directly impacts your overall budget. Prices vary widely based on technology, materials, and security standards. Premium brands offer advanced features but come at a higher price. Entry-level options are available but may lack robust security certifications. 

Below is a suggested pricing guide based on popular brands available in the UK market:

2. Lock Type & Door Complexity

The type of smart lock you choose and your door’s construction significantly influence installation pricing. Some locks fit directly onto existing fixtures, while others require structural adjustments. Doors vary in material and locking mechanisms, which affect labour time and complexity.

3. Labour Time & Complexity

Labour time plays a critical role in your final installation cost. Simple replacements usually take 60 to 90 minutes and cost around £75 to £125 per hour. However, complex installations involving multipoint systems, mortice locks, or biometric features can extend to 2–3 hours.

Drilling, door adjustments, or wiring add significant labour charges. While some installers offer a fixed rate, hourly pricing increases your costs if unexpected issues arise during the fitting process.

4. Number of Locks

Installing multiple smart locks in a single visit affects your overall cost. More locks increase labour time but may reduce the per-lock installation rate. Installers frequently offer discounted pricing when fitting two or more locks together. 

For example, installing two locks may cost between £320 and £510 instead of £190 to £320 per lock separately. However, each added lock still requires extra time and complexity, especially if installed on different door types.

5. Timing and Urgency

The timing of your installation directly impacts pricing. Standard weekday appointments typically range from £190 to £320 per lock. Booking during evenings, weekends, or holidays often adds a 20% to 50% surcharge. 

Rates for emergency or short-notice requests usually start at £320 and above. Due to limited availability, installers charge premium fees for out-of-hours services. To manage your budget effectively, schedule your installation during normal business hours. This approach keeps your overall costs predictable and avoids unnecessary surcharges.

6. Integration & Setup

Integrating your smart lock with home devices adds convenience, but also influences installation pricing. Basic setup is often included, yet advanced integrations can raise costs. If you plan to connect your lock to multiple systems like alarms, cameras, or smart hubs, installers may charge extra for the technical setup. 

Below is a suggested table outlining common integration types and potential additional costs:

DIY vs Professional Smart Lock Installation: When to Choose What? 

Choosing between DIY and professional smart lock installation depends on your skills, tools, and the lock’s complexity. Both options have distinct advantages, but the right choice saves you time, money, and frustration. Below is a clear guide on when to choose each option.

When to Choose DIY Installation

• You have basic tools like drills, screwdrivers, and measurement guides.
• The lock is retrofit-friendly and designed for easy home installation.
• Your door structure matches the lock’s requirements with no modifications needed.
• You’re comfortable following technical instructions for both hardware and app setup.
• Saving the £190 to £320 professional fee is a priority.
• You have previous experience with hardware installations or similar tasks.

When to Choose Professional Installation

• The lock type is complex, such as biometric or video-integrated systems.
• Your door is uPVC, composite, or non-standard, requiring adjustments.
• Wiring, drilling, or carpentry is necessary to fit the lock properly.
• You want full configuration, including app integration and smart home connections.
• Your home insurance prefers or requires professional installation.
• Time constraints or a lack of tools make DIY impractical.

Additional Costs and Considerations for Installing the Smart Lock

1. Door Modifications (Drilling/Retrofitting)

If your door doesn’t match the new smart lock’s dimensions, modifications are necessary. This includes drilling new holes, chiseling out wood, or resizing existing cut-outs. Installers typically charge £65 to £130, depending on the extent of the work. Due to their density, uPVC and composite doors often require more labour.

2. Travel and Call-Out Fees

Most installers apply a £65 to £130 call-out fee, particularly if you live beyond their regular service area. This fee usually covers the installer’s travel time and the first hour of labour. 

This charge may be higher in remote or rural regions for additional travel. Call-out fees might still apply if you’re in a major city like London, but are generally within the lower end of the range.

3. Out-of-Hours Surcharges

Scheduling installation during evenings, weekends, or public holidays incurs extra charges. Installers typically apply a 20% to 50% surcharge on the base rate. For instance, a standard £190 weekday installation can cost £230 to £290 when booked outside regular hours. 

Emergency same-day installations may cost even more, especially if the job demands immediate response. Planning during weekday business hours keeps your costs predictable.

4. Old Lock Disposal or Extra Keys

Many installers remove and dispose of your old lock at no extra charge, but some may request a £15 to £25 fee for this service. If your smart lock includes a physical key backup, additional keys cost £6 to £13 each to cut. 

This is a modest but essential expense for larger households or properties needing multiple key copies. Always confirm whether key cutting is offered during installation.

5. Integration with Other Systems

Smart locks can integrate with alarms, CCTV, or smart home hubs for enhanced security and convenience. Installers typically charge £65 to £130 per system for integration services. A full smart home ecosystem setup, where the lock coordinates with lights, alarms, and cameras, may cost £130 to £200+. 

The more devices involved, the longer the configuration time, adding to your final bill. Clarify your integration needs beforehand to avoid unexpected charges.

6. Cancellation or Missed Appointment Fees

If you cancel within 24 hours of the scheduled time or miss the appointment entirely, expect a £65 to £100 penalty. This covers the installer’s lost time and any preparation costs. 

Some providers may waive the fee with sufficient notice, but this isn’t guaranteed. Always review the cancellation policy when booking to avoid these extra charges.

Quick Tips to Reduce Smart Lock Installation Costs

• Schedule on weekdays to avoid evening, weekend, or holiday surcharges.
• Choose locks compatible with your door to skip modification charges.
• Install multiple locks in one visit to secure per-lock discounts.
• Provide accurate door and lock details upfront to get fixed quotes.
• Handle basic setup tasks yourself, like app pairing and Wi-Fi connection.
• Book local installers to avoid high travel or call-out fees.

How To Select a Qualified Locksmith Or Installer To Install Your Smart Lock?

Choosing a qualified locksmith or installer for your smart lock is essential for both security and proper functionality. Rushing this decision risks poor fitting or compatibility issues. Focus on these key factors:

Certifications and Accreditations

Always choose a locksmith accredited by recognised UK bodies like the Master Locksmiths Association (MLA). Certification confirms their skills, ethical standards, and experience with both traditional and smart locks.

Experience with Smart Locks

Select an installer with documented experience in fitting smart locks. Smart devices require technical knowledge beyond standard locks, especially for features like app integration and smart home connectivity.

Transparent Pricing and Written Quotes

Reliable installers provide clear, itemised quotes in writing. This prevents hidden charges and clarifies prices, such as travel, labour, integration, and potential door modifications.

Insurance and Warranty

Check that the installer carries public liability insurance and offers a workmanship warranty. This protects you from costs arising from installation errors or accidental property damage.

Customer Reviews and References

Research reviews on platforms like Trustpilot or Google. Positive feedback and high ratings indicate reliability. Ask for direct references to verify their track record with similar installations.

In Closing

Smart lock installation is an investment that blends security, convenience, and modern technology. Knowing the actual cost helps you make informed decisions without surprises. Each factor plays a role in your final expense, from installation timing to lock complexity. Professional fitting guarantees proper alignment, security standards, and complete system integration.
