Commercial Security Tips

Protect Your Business — What to Do First

If your premises has been broken into or your lock is compromised, here's what to do before our locksmith arrives.

1

Don't Force the Door

Forcing a locked commercial door can cause expensive damage to the frame, lock mechanism or door itself. Our locksmiths attempt non-destructive entry first — often saving hundreds in repair costs.

2

After a Break-In: Don't Clean Up Yet

If your premises has been forced, call the police before touching anything. Once you have a crime reference number, call us for emergency boarding and lock replacement. We'll have you secure within the hour.

3

Check Your Insurance Requirements

Many commercial insurance policies require BS3621 mortice locks or 3-star TS007 cylinders. We can tell you on-site whether your existing locks meet the policy spec — and replace them if not.

What Our Clients Say

Trusted by South London Businesses & Landlords

Read what offices, landlords and businesses across South London say about our commercial locksmith service.

Called late on a Friday evening after being locked out of our office before a Monday morning presentation. Arrived within 25 minutes, got in without damaging the door. Absolutely brilliant service. Will use again.

I manage several HMOs in South London and use this locksmith for all my end-of-tenancy lock changes. Competitive trade rates, always on time, and the work is done properly. Highly recommended for landlords.

Shop was broken into overnight. Called at 6am, locksmith was here by 6:35. Boarded up the damaged frame and replaced the lock with a high-security cylinder. Back open for business by 9am. Cannot recommend enough.

Do you work outside normal business hours?

Can you set up a master key system for my property?

Yes. We design and install master key systems tailored to your specific layout — whether it's a single office, multi-floor building or a portfolio of HMOs. One master key opens every door while individual tenants or staff have access only to their own area. Call us to discuss your requirements.

Can you help with fire door and panic hardware compliance?

Yes. We can advise on and install panic hardware, fire door closers and exit hardware that complies with BS EN 1125 standards. This is particularly important for HMOs, multi-occupancy offices and commercial premises subject to fire safety regulations. Contact us to discuss your building's specific requirements.

What commercial properties do you work with?

We work with all types of commercial premises across South London, including offices, retail shops, restaurants, cafes, warehouses, storage units, HMOs, commercial units and multi-occupancy buildings. We also work regularly with letting agents, property managers and landlords with multi-property portfolios.

Are your locksmiths qualified and insured for commercial work?

Yes. Our locksmiths are Level 3 City & Guilds qualified, fully insured and DBS checked. We supply and install locks to British Standard BS3621 and TS007 3-star anti-snap cylinders. This satisfies most commercial insurance policy requirements, and we can confirm specification in writing on request.

Do you provide security surveys between tenancies?

Yes. We offer security surveys between tenancies and for businesses looking to upgrade their existing setup. We assess your current locks, identify any vulnerabilities and recommend cost-effective upgrades that meet insurance and landlord licensing requirements. Contact us to arrange a survey.
