Frequently Asked Questions

How many Security Systems businesses are for sale in London?

Serava.AI has mapped 51 acquisition-ready security systems businesses in London, GB. These are active, operating businesses scored for owner exit readiness, years in business, and financial profile. Most are off-market — they have not yet engaged a broker or listed on any marketplace.

What is the typical asking price for a Security Systems business in London?

Security Systems businesses in London typically trade at 3x to 6x EBITDA. A business with $2M revenue and 12% margins ($240k EBITDA) would price between $720k and $1.44M. Businesses with recurring contracts, strong owner tenure, and clean books command the higher end of that range.

Why buy an Security Systems business in London instead of starting one?

Acquiring an existing security systems business in London gives you an established customer base, trained staff, and immediate cash flow — without the 2-3 year ramp of a startup. Businesses in our database average 19 years in operation, meaning they have proven their model in the local market.

How do I find off-market Security Systems businesses in London?

Most security systems acquisitions in London happen off-market. Serava.AI identifies succession-ready owners using tenure and business age signals, then reaches out directly on your behalf before they hire an investment banker. This gives you proprietary access before any competing buyer sees the deal.
