Building a Compliance Calendar

A compliance calendar is a single, dated record of every certificate, licence and check your properties need, organised so you can see at a glance what is coming due across your whole portfolio, not just the next renewal you happen to remember. Building one properly means more than jotting expiry dates into a diary: it means listing every recurring item per property, working out realistic lead times for booking each renewal, and reviewing the whole thing on a set schedule rather than only when something is about to lapse.

This guide walks through how to build a compliance calendar from scratch, what columns and categories to include, and how to structure it so it scales as your portfolio grows past the point where you can hold every date in your head.

What to include per property

Start by listing every recurring compliance item that applies to a given property, since the full list is usually longer than landlords expect once you account for every certificate and check:

• Gas safety record, renewed every 12 months, if the property has any gas appliance.
• EICR, renewed at least every 5 years.
• EPC, valid for 10 years.
• Smoke and carbon monoxide alarm testing, at the start of every new tenancy.
• HMO licence or selective licensing, if applicable, typically renewed every 3 to 5 years depending on the local authority.
• Deposit protection, a one-off deadline per tenancy (30 days from receipt) rather than a recurring renewal, but worth tracking against each new tenancy start.
• Legionella risk assessment review, not a fixed legal renewal but good practice to revisit every couple of years or after a change to the water system.
• Insurance renewal, typically annual, and worth tracking alongside safety certificates even though it is not a compliance certificate as such.

Not every property needs every item on this list. A single self-contained flat with electric heating, for example, has no gas safety requirement, while an HMO adds licensing and additional fire safety items on top of the standard set. Build the list property by property rather than applying one template blindly across a mixed portfolio.

Structuring the calendar

A workable compliance calendar needs, at minimum, four columns for each item: the certificate or check type, the property it applies to, the current expiry or due date, and a target booking date set well ahead of that expiry.

The "book by" column matters as much as the expiry date itself, since the point of a calendar is to prompt action before a deadline, not simply to record when something ran out. A gas safety renewal booked six weeks ahead gives room to rebook if the engineer is unavailable; an EICR renewal, given the longer lead time typically needed to source a qualified electrician and complete any remedial work, is worth flagging two to three months ahead rather than a few weeks.

Staggering renewal dates across a portfolio

If you acquire properties at different times, their certificates naturally fall on different dates throughout the year, which is generally easier to manage than everything renewing in the same month. If several properties happen to cluster around the same renewal window, for example because you bought several in a single buying spree, it is worth deliberately staggering some renewals earlier or later by a few weeks when you first set up the calendar, so you are not coordinating five engineer visits and five sets of tenant access in the same fortnight every year.

This is easier to do proactively, when you first build the calendar, than to fix later once a cluster of dates has already been locked in by several years of renewals landing on the same schedule.

Setting review cadence

A calendar only works if someone actually looks at it regularly. A sensible minimum is:

• Weekly or fortnightly, scan for anything due to book within the next month.
• Monthly, a fuller review of every property's compliance status, catching anything that might have been missed in the weekly scan.
• Annually, a full audit against your actual certificates and licences, confirming the calendar still matches reality rather than drifting out of sync with what has genuinely been renewed.

The annual audit matters more than it sounds, because a calendar that was accurate when built two years ago can quietly drift if a renewal was booked slightly early or late, or a certificate was renewed by a letting agent without the date being fed back into your own record.

Common mistakes

• Building the calendar around expiry dates only, with no booking lead time. By the time an item shows as "due," it is often too late to book comfortably before it lapses.
• Keeping the calendar in a format only one person can update. A spreadsheet on a single person's laptop is a single point of failure if that person is away when a renewal comes up.
• Forgetting items without a fixed annual rhythm, such as HMO licences renewing every three or five years, which are easy to lose track of precisely because they come around so infrequently.
• Never auditing the calendar against reality. A calendar that has not been checked against actual certificates in over a year is a risk in itself, since it can show a false sense of security.

How Property HQ helps

Property HQ builds this compliance calendar automatically from the certificates and dates already logged against each property, with reminders sent well ahead of each renewal so you are working from the "book by" date rather than the expiry date itself. As your portfolio grows, that shift from a manually maintained spreadsheet to a system that tracks every property's dates in one place is usually what keeps compliance genuinely under control. See our landlord certificates checklist for the full list of items most portfolios need to track, and our landlord legal responsibilities guide for the wider legal duties a compliance calendar helps you stay ahead of.
