Key figures

Revenue not disclosed

Building Monitoring Services Limited’s accounts for the year to 31 Dec 2024 contain a balance sheet but no profit & loss account, so its revenue and profit are not public. UK small and micro-entity companies are not required to publish a P&L — this is normal and says nothing about how the business is performing.

We never estimate revenue. Below you’ll find the balance-sheet figures that were filed — useful as indirect signals of momentum, but they are not revenue or profit.
