The asset register is where the boilers, lifts, fire panels, emergency lighting, AC units and IT kit across your estate live. It's a single, org-wide **data grid** that works like a spreadsheet — fast to scan, fast to edit, fast to bulk-update. The org-wide asset register as a spreadsheet-style data grid ## A Real Data Grid Assets is a true grid, not a list of cards: * **Inline edit** — double-click (or just start typing) in a cell to edit; Tab moves to the next cell. * **Fill down** — drag the fill handle to copy a value down a column. * **Filter, sort and search** from the toolbar, with **saved views** so a filtered slice is one click away. * **Frozen header and toolbar** — they stay put while the rows scroll. * **Multi-select** rows for bulk actions, and a **+ Add N rows** footer to append in bulk. * **CSV import** (with a downloadable sample) and export, for moving a register in or out. * Cmd Z to undo — including restoring rows you've deleted. See [Keyboard shortcuts](/interface/keyboard-shortcuts#data-grids) for the full set of grid keys. ## What an Asset Holds | Column | Notes | | ---------------------------------------- | ------------------------------------------------------------ | | **Asset Nr** | Your tag / reference (e.g. `LIFT-02`) | | **Name** | Plain-English label | | **Type** | Boiler, Lift, Fire Alarm Panel, Emergency Lighting, AC Unit… | | **Quantity** | One line can represent a bulk run (e.g. 12 luminaires) | | **Tags** | Free tags — Critical, Fire Safety, IT… | | **Location** | Where it sits on site | | **Manufacturer / Model / Serial number** | Make and identity | | **Install batch** | Groups assets installed together | | **Installed at / Warranty end** | Lifecycle dates | | **Service life** | Expected years before replacement | Assets are **org-wide**: scope to a single property and the grid narrows to that site; clear the scope to see the whole estate. ## Replacements and Fault History Service life plus install date drive the [Replacements](/compliance/planned-maintenance) register and capital forecast — so kit nearing end-of-life surfaces before it fails. When work orders are logged against an asset, its **fault history** feeds the Investigations signals that flag a unit failing more often than its peers. Repairs and services logged against an asset build its fault history.
