Property HQ vs Spreadsheets

A spreadsheet is a perfectly reasonable way to run one or two rental properties: a tab for income and costs, a few cells for certificate dates, and enough discipline to update it monthly. The comparison with dedicated software like Property HQ is not "spreadsheets are bad", it is a question of which specific tasks a spreadsheet does well, which ones it quietly fails at as a portfolio grows, and whether the failure modes matter enough to your situation to justify switching.

This guide compares the two approaches criteria by criteria, rather than arguing in the abstract, and is honest about where a spreadsheet still holds up.

Where a spreadsheet holds up well

For a single property, or two properties with straightforward finances, a well-built spreadsheet can genuinely work for years. It costs nothing beyond the time to build it, it is completely under your control, and it can be shaped exactly to how you think about your own numbers rather than fitting someone else's template. If your admin today consists of updating a couple of tabs once a month and it has never caused a real problem, that is a legitimate answer, not a failure to modernise.

The strain tends to show up not from the number of properties alone, but from three specific pressures: more than one bank account feeding the same tracker, certificate dates that need chasing rather than just recording, and more than one person needing to see or update the same figures.

A criteria-by-criteria comparison

Rather than a general "software is better" claim, here is how the two approaches compare on the tasks that actually matter to most landlords:

None of this means every row favours software for every landlord. A spreadsheet genuinely wins on cost and on flexibility to shape it however you like. Dedicated software wins where the task depends on something happening automatically and on time, rather than on someone remembering to check a cell.

The failure modes that matter

The reason spreadsheets cause real problems are rarely dramatic. They are quiet: a formula that was copied down incorrectly and has been slightly wrong for six months, a certificate renewal cell that nobody looked at because there was no reminder attached to it, or two versions of the same file circulating after a co-owner made an edit on their own laptop. None of these show up until something forces the issue, usually a tax return, a dispute, or a lapsed certificate discovered at the worst possible time.

A useful test is to time your last quarterly reconciliation, including chasing down a missing receipt or working out which property a particular payment belonged to. If that took more than an hour or two, the manual effort a spreadsheet demands is probably costing you more in time than a subscription would cost in money, even before counting the risk of an error going unnoticed. Our guide to landlord accounting software in the UK sets out where that breakdown point tends to fall in more detail, typically somewhere around three to five properties or as soon as Making Tax Digital applies to you.

A worked example. A landlord with five properties tracked everything in a single spreadsheet: one tab per property for income and costs, and a "certificates" tab listing expiry dates. The spreadsheet itself was well organised, but two things went unnoticed for months. A copied formula on one property's tab had been referencing the wrong column since a row was inserted the previous year, understating that property's costs by around £400. Separately, a gas safety renewal cell showed a date that had already been quietly superseded by an engineer's visit two months earlier, because the spreadsheet was never updated after the certificate arrived by email. Neither error was caused by carelessness. Both were the kind of drift that a static file with no built-in checks or reminders allows to accumulate silently, and both were only caught during an unrelated year-end review.

When it is still reasonable to stick with a spreadsheet

Sticking with a spreadsheet is the right call, not just the cheap one, if all of the following are true: you manage one or two properties, you are the only person who needs to see or edit the figures, you already have a working system for compliance reminders that does not depend on the spreadsheet itself, and your current process has not caused a genuine problem in the past year. If any of those stop being true, particularly the compliance reminder point, the risk profile changes even if the number of properties has not.

Making the move without losing your history

If you do decide to switch, the main practical risk is losing continuity, not the switch itself. Before moving off a spreadsheet, export or screenshot at least the past two tax years of figures, and list every certificate and its actual expiry date rather than relying on memory of what the spreadsheet said. Most of the actual work in moving to dedicated software is this one-off transfer of historic data; day-to-day use afterwards is usually simpler than what it replaces, not more complex, since the software is doing the reconciliation and reminders you were previously doing by hand. Our guide to choosing software for a 10-property portfolio covers the practicalities of that transition at the scale where it usually becomes worth doing.

How Property HQ helps

Property HQ is built as the step up from a spreadsheet for self-managing landlords with roughly two to fifty properties: bank reconciliation through Open Banking, compliance reminders sent ahead of the deadline rather than sitting in a cell you have to check, and documents attached to the property and tenancy they belong to. It is not automatically the right answer for every landlord, and a well-run spreadsheet for a single property is a legitimate choice, not a mistake. If you are still deciding which category of tool fits your portfolio, our wider guide to landlord software in the UK and our comparison of the best UK landlord software in 2026 cover how several tools, including Property HQ, stack up against the criteria in this guide.
