The fire extinguisher was last checked three years ago. The ventilation filter should be changed monthly, but since the colleague retired, nobody does it any more. And when the customer asks for the maintenance record for their system, all anyone can find is a completed sheet from 2023.
Recurring inspections rarely fail because of skill — they fail because of remembering and recording. This guide shows how to build a maintenance schedule that works in everyday life, how to deal with missed dates and what a record should contain.
Why the record matters
- Manufacturer's warranty: many warranties require maintenance as specified. Without proof it gets difficult.
- Liability: after damage, the question is whether the system was maintained. A complete record shows that you took care of it.
- Insurers and authorities: fire protection, pressure equipment, lifts or food come with inspection duties. The question is not whether you did it, but whether you can show it.
- Customers: whoever looks after systems at a customer's site will be asked for the maintenance log — at the latest when something breaks down.
Which inspections are required for your systems is stated in the manufacturer's information, in your industry's regulations or by the competent authority. This guide shows how to organise them.
The maintenance schedule: five questions per inspection
For each recurring inspection, answer the same five questions:
- What? The device or process, named so that everyone finds it: "Heat pump building B", not "HP2".
- How often? Daily, weekly, monthly, yearly, or "every 3 months". Stick to what the manufacturer or the regulation specifies.
- Who carries it out? One person, a team or an external company. "Somebody" is nobody.
- Who reviews it? Someone looks at the result, especially when defects are reported.
- What is recorded? Readings, photos, defects, signature. Ideally as a checklist that looks the same every time.
A maintenance schedule as a table looks like this:
| Object | Inspection | Rhythm | Carried out by | Reviewed by | Next due |
|---|---|---|---|---|---|
| Heat pump building B | Pressure, filter, visual check | every 6 months | Installer team North | Workshop manager | 15 March |
| Fire extinguisher ground floor | Visual check, seal, pressure | monthly | Caretaker | Safety officer | 1 November |
| Till, branch | Cash count | daily Mon–Sat | Shift lead | Branch manager | tomorrow |
| Workshop ventilation | Filter change | monthly | external company | Workshop manager | 20 November |
Staying on top of due dates
A schedule on paper says what should be done. It does not say what is due today. Three habits help:
- Calculate due dates, do not copy them. Every date follows from the rhythm and the start date. Whoever transfers dates into a calendar by hand forgets half of them the following year.
- One place for "due today" and "overdue". Whoever wants to know in the morning what is coming up should not have to check five lists.
- Think about month ends and holidays. "On the 31st of every month" does not exist in February. Decide that the last day of the month applies.
When a date is missed
It will happen: holidays, illness, a busy week. What matters is what stays visible afterwards.
- Missed stays missed. A skipped date should not quietly disappear when the next one comes up. Otherwise the record shows a gap that nobody noticed.
- Catching up is allowed, but marked. If an inspection is done late, the record states which date it counts for and when it was actually done.
- Find the cause. If the same date is missed again and again, either the rhythm or the responsibility is wrong.
Involving external companies
Cleaning, maintenance or service companies often carry out exactly the inspections you need to document. To get their work into your record:
- The same checklist for everyone. The external company fills in the same checklist as your own people, not its own form.
- Remind them in time. A link shortly before the due date works better than a maintenance contract in a binder.
- Protect access. The link alone should not be enough: an access code the company receives separately means a forwarded email is not sufficient.
- See the result immediately. Defects, photos and signature are there as soon as the company has finished, not only with the invoice.
Following defects through to the end
An inspection is only finished when the defects found have been fixed. For each defect, record:
- What was found, with a photo.
- Who is dealing with it.
- When it was fixed, and by whom.
Open defects belong where people see them: with the device, not in a notebook. And whoever reviews the inspection decides whether a defect must be fixed immediately or can wait until the next maintenance.
Common mistakes
| Mistake | Consequence | Better |
|---|---|---|
| Dates entered by hand in a calendar | Half are missing next year | Set the rhythm, calculate the dates |
| "The team" is responsible | Nobody feels addressed | One person or a clear handover |
| Missed dates disappear | Unnoticed gaps in the record | Keep missed visible, mark catch-ups |
| Every company its own form | Records cannot be compared | One checklist for everyone |
| Defects only noted down | They stay open | Open until someone reports "fixed" |
| Logs in a paper binder | Not at hand for the customer or inspector | Digital, per object, exportable as PDF |
Summary
Recurring inspections need five answers: what, how often, who carries it out, who reviews it and what is recorded. Due dates are calculated, not copied, and missed dates stay visible until they are caught up on. Defects are only done when they are fixed. Then the record is not extra work — it is created while you work.
