Commercial lease management software tracks the lease dates that cost real money when they slip — break clauses, rent reviews and expiry — and reminds you before each one passes. In the UK, options run from a free spreadsheet, through £8–£19 a month deadline trackers, to portfolio systems from £295 a month and enterprise platforms priced on application.

Most of that software exists to solve one expensive problem: a date arrives before anyone has done the thinking, and the default happens instead of the decision. A missed break clause can lock a tenant into years of rent they meant to escape; a rent review that drifts past its trigger date can cost a landlord the uplift. This guide covers what the software actually does, what it costs in the UK — with real prices, because almost every vendor hides theirs — and, honestly, when a spreadsheet is still enough. We build and run a commercial lease database that a UK property firm uses every day, so this is written from the operating end of the problem, not from a brochure.

What does commercial lease management software actually do?

Strip away the marketing and it does four things:

  • Holds every lease in one place — property, unit, tenant, key terms and documents — instead of a folder per building and a spreadsheet someone keeps a private copy of.
  • Tracks the critical dates — lease expiry, break dates, the break-notice deadline (the date that actually matters), rent review dates, and often service-charge, insurance and dilapidations windows too.
  • Reminds you in time — surfaces each event far enough ahead that you can still act on it, rather than after the window has closed.
  • Reports across the portfolio — what expires this year, what income is under review, what is void — without rebuilding the same pivot table every month.

Here is where the search results mislead you. Much of the software that ranks for "lease reminder software" is American and built around residential renewals: chasing a tenant to re-sign before the unit goes vacant. UK commercial leases are a different animal. The dates that matter are set by the lease and by the Landlord and Tenant Act 1954 — section 25 and section 26 notices served no less than 6 and no more than 12 months before the termination date, break conditions the courts enforce strictly, five-yearly rent reviews with their own machinery. Software built for residential lettings does not know any of that. For a UK commercial portfolio, that distinction is the whole game.

Do you actually need software, or is a spreadsheet enough?

Honest answer: for a handful of leases, a spreadsheet is genuinely enough, and we would rather say so than sell you something. We publish a free Excel tracker whose columns mirror the fields our own system uses, with the break-notice deadline and days-to-next-event already calculated. Three rules make it survive contact with reality: one named owner who checks it weekly; one copy, because the moment there are two you have two opinions instead of a tracker; and the rent kept on the same row as the dates, so a glance shows which deadline is worth £8,000 and which is worth £80,000.

A spreadsheet starts to crack past what one person holds in their head — more than a couple of dozen leases, more than one person editing, contact history scattered across inboxes, or monthly reporting that means rebuilding the same view by hand. The failure is never the formula; it is versioning, access, and the fact that a spreadsheet cannot chase anyone. The real signal to move is when people stop trusting it: when they double-check it against their own notes, or a stale copy causes a near-miss. That loss of trust usually arrives before a missed date does, and it is the moment software earns its cost.

What does commercial lease management software cost in the UK?

This is the question the market refuses to answer in public. The established platforms — Re-Leased, MRI, Yardi and most of the field — quote on application, per demo, after a sales call. Even a rival's own "best commercial property software" guide can run to 3,000 words with a "pricing transparency" column and still not print a single number. So here is a straight table, with the figures that are actually published, ours included.

OptionTypical UK costWhat you getBest for
Spreadsheet (our free template)£0Every key date with the break-notice deadline calculated; cells turn amber at 180 days, red at 90A handful of leases, one careful owner
Deadline tracker (e.g. LeaseAlert)£0–£19/monthEscalating reminders on critical dates plus template letters — a lightweight tool, not a portfolio systemA tenant or owner who only needs alerts on a few leases
TenureBook — Standard£295/month (3 seats)One system for companies, properties, leases, financials and documents, with reminders counting down on the dashboard and a built-in Excel import that reads your existing columnsA small commercial portfolio that wants one trusted system, live within a minute of checkout

Bespoke build£7,000 to build + £100/monthA system built around workflows no product fits — see our custom system cost guideRequirements an off-the-shelf shape cannot meet

Extra seats are £250 a year (about £20.83 a month) each on any TenureBook plan. The only genuinely published competitor price we could find is LeaseAlert's — free for a single lease, £8 a month for up to three, £19 a month for unlimited leases with team sharing — which is fair for a pure reminder tool. Everything heavier than that hides behind a quote, which is exactly why buyers find this market so hard to compare.

The main options, honestly

A spreadsheet

Free, universal, and genuinely fine for a handful of leases with one disciplined owner. Our free tracker and the schedule to work to will take you a long way. It stops coping on versioning and reporting, not on the maths.

A dedicated deadline tracker

Tools like LeaseAlert do one job well: they watch your break clauses, rent reviews, expiries and dilapidations dates and send escalating reminders — typically at six months, three months, one month, two weeks and one week — with plain-English notes on what to do. At £0 to £19 a month they are the cheapest way to stop missing a date. What they are not is a system of record: they remind you, but they do not hold your properties, financials, documents and contact history in one place, or report across a portfolio.

UK commercial property platforms

Re-Leased, MRI Qube, Yardi and WebTerrier are the established commercial platforms, built for managing agents and larger landlords who need full property accounting, service-charge reconciliation and client-money handling alongside the lease dates. They are capable and comprehensive, and priced accordingly — on application, usually with an onboarding project. If you manage a large portfolio on behalf of others, this is the tier you are shopping in.

Residential landlord software

Landlord Vision, Arthur and similar tools are built primarily for residential and buy-to-let portfolios: rent collection, tenancy admin, Making Tax Digital. Some handle light commercial exposure, such as a single unit on an FRI lease. If your holdings are mostly residential with a little commercial, they can fit; for a genuinely commercial portfolio they are the wrong shape.

A ready-made commercial database (TenureBook)

This is the gap we built for: a firm with a real commercial portfolio that has outgrown spreadsheets but does not need — or want to pay for — an enterprise platform. TenureBook holds occupiers, properties, leases, financials, documents and deals in one book, and surfaces every upcoming lease event with reminders well before the deadline lands, so nothing that costs money slips past. The same software runs a real UK commercial-property portfolio every day; it costs £295 a month to start, you are live within a minute of checkout, and the built-in Excel import brings your existing spreadsheets straight in. It is a lease and portfolio database with the financials attached to each lease, not a full property-accounting and client-money suite — which is why it costs a fraction of the enterprise platforms.

A bespoke build

When no product fits the way you work, a system built to your exact workflow is the answer. It costs more up front — from £7,000 plus £100 a month in our case — and is worth it when the shape of your operation is the point, not an inconvenience to design around. We build these, and we will tell you when you do not need one.

How to choose the right one for you

Work down this list and stop at the first line that describes you:

  • Fewer than roughly 20 leases, one person on top of them? Use a spreadsheet — our free template and the schedule to work to are enough.
  • Only need reminders, on a few leases? A dedicated deadline tracker at £8–£19 a month is the cheapest fix.
  • A growing commercial portfolio that needs one trusted system, not just alerts? A ready-made commercial database like TenureBook, from £295 a month, is the middle ground the market is missing.
  • Managing a large portfolio for others, needing full accounting and client money? Shop the enterprise platforms and budget for a quote and an onboarding project.
  • A workflow no product fits? A bespoke build, once you have ruled out the cheaper options above.

The honest through-line: buy the least software that solves your actual problem. A reminder tool is cheap; a system of record is worth paying for once trust in the spreadsheet has gone; enterprise accounting only earns its keep if you genuinely handle other people's money. If you are not sure which line you are on, book a short call and we will tell you straight — including when the free template is all you need. We also answer by email if you would rather write.
