A call at 10pm on a Saturday
Some clients need you outside office hours: a care home with a failed hot water system, a hotel with a guest complaint about water, a site that has had a result they want to discuss urgently, a facilities manager who has just found a flooded plant room. The call goes to whoever has the on-call phone this week.
The on-call engineer handles it as best they can. They might give advice within their competence, attend site, or arrange something for the morning. What they rarely do is write it all down properly, because it is late and they are driving. On Monday, the office hears a summary, the client's call is not in any system, the attendance is not billed, and the follow-up visit that was promised is not booked.
Why out of hours work vanishes
- The on-call phone is a separate mobile, not connected to any system.
- The engineer has no access to the site's records out of hours.
- Notes are written on paper or in a text message to themselves.
- Handover to the office is a conversation, not a record.
- Callout rates depend on the contract, which the engineer cannot see.
What lost callouts cost you
Unbilled attendances are the direct cost. Missed follow-ups are worse: the client was promised a visit on Monday and nobody booked it. There is also a record-keeping gap, because a call that shaped what happened at a site is not in the site's history.
On-call engineers find the rota more stressful when they have no information to hand, which matters in a small team where the rota comes round often.
A callout log that follows the call
- The out of hours number routes through a telephony service such as Twilio, which logs the caller number, time and a recording if you choose to keep one.
- The on-call engineer receives the call and a record on their phone with the matching client and site, if the number is known, and quick access to the site's asset list, recent reports and contacts.
- The engineer logs the outcome on a short form: advice given, attended, follow-up needed, or passed to the client's own contractor, with notes.
- If they attend, it becomes a callout job with times on site, recorded like any other visit.
- At the start of the working day, the office gets a handover list of every overnight call with its outcome and any follow-up still to book.
- Attendances create billing lines at the callout rate in the client's contract, for accounts to check.
| Outcome | Created automatically |
|---|---|
| Advice given by phone | Call record on site history |
| Attended site | Callout job, report, billing line |
| Follow-up needed | Task on the office handover list |
| Not our contract or site | Call record with note, no billing |
Whatever the engineer says to the client stays their professional judgement within your procedures. The system makes sure it is recorded and followed up.
Monday morning with a proper handover
The office starts the week with a list, not a story. Follow-up visits are booked first thing. Accounts see billable callouts without asking. The site's history shows the call, what was said and what happened, which helps the engineer who visits next.
The on-call engineer gets something useful too: when an unfamiliar site rings at night, they can see its asset list and last report on their phone before deciding whether to attend.
Is on-call working for you?
