Access Control System Installation in Sutton & South London

Controlling who can enter your building — and exactly when — is one of the simplest ways to strengthen security without disrupting day-to-day operations. Kojo Electrics designs, installs, and maintains access control systems for commercial offices, residential blocks, and private facilities across Sutton and South London, giving you full oversight of every entry point.

From straightforward keypad entry to advanced smart card and biometric systems, every installation is built around your building's layout, security requirements, and how your occupants actually move through the space day to day.

What is an access control system?

An access control system replaces (or works alongside) traditional keys with electronic credentials — key fobs, smart cards, PIN codes, or biometric data such as fingerprints. Each entry point can be set with its own permissions, so you decide who gets in, which doors they can use, and what times of day access is allowed.

Types of access control we install

• Keypad entry – a cost-effective option for smaller offices or single entry points
• Smart card and fob systems – ideal for multi-tenant buildings and residential blocks where individual audit trails matter
• Biometric access – fingerprint or facial recognition for high-security areas where credential sharing is a risk
• Cloud-managed systems – remote management of permissions and access logs from anywhere
• Integrated systems – access control linked with CCTV and intercom for a single, coordinated security setup

Fire safety compliance built in

Any door forming part of a fire escape route has to remain safely operable during an emergency, in line with BS 7273-4. This means electronically locked doors must be designed to release automatically if the fire alarm activates or power is lost, and must always include a manual override — never a system that locks people in. We design every installation with this integration in mind from the outset, not as an afterthought.

Access Control Systems: Frequently Asked Questions

Do access control doors have to unlock automatically in a fire?

Yes. Any electronically locked door on a fire escape route must be designed to fail safe — meaning it releases automatically if the fire alarm triggers or power is lost. This is required under BS 7273-4 and reinforced by the Regulatory Reform (Fire Safety) Order 2005, which makes the building's "responsible person" accountable for keeping escape routes clear and usable at all times.

What's the difference between a keypad, card, and biometric system?

A keypad relies on a shared PIN code, which is simple and low-cost but offers no way to identify exactly who entered. Card or fob systems assign a unique credential to each person, giving you an individual audit trail. Biometric systems go a step further by tying access to a physical trait like a fingerprint, removing the risk of a credential being lost, shared, or copied.

Can access control be combined with CCTV and intercom?

Yes, and it's increasingly common in commercial and residential buildings. Integrating these systems means a single platform can manage entry permissions, video footage, and visitor access together, giving building managers a clearer overview instead of juggling separate systems.

Is biometric access control legal for offices and residential blocks in the UK?

Yes, but biometric data counts as sensitive personal data under UK GDPR, so it must be collected, stored, and processed with appropriate safeguards and a lawful basis. Most commercial installations use it alongside a fallback method, such as a card or PIN, for anyone who doesn't wish to enrol biometrically.

How long does an access control installation take?

This depends on the size of the building and number of entry points. A single-door keypad system can often be fitted in a day, while a multi-door system integrated with fire alarms and CCTV across a larger building will take longer to design, wire, and commission properly.

Does an access control system need regular maintenance?

Yes. Locks, power supplies, and fire alarm interfaces should be tested periodically to confirm doors still release correctly in an emergency. This isn't just good practice — where access control is integrated with a fire escape route, keeping it in working order is a legal obligation on the building's responsible person.
