Out-of-hours work can be the best-paid work a sole trader plumber does, but only if two things are in place: a night rate high enough that you are glad to get up, and a way of filtering calls so you are only woken for genuine emergencies. Without both, it quietly turns into unpaid on-call duty. This guide covers whether to offer it, how to price it, how to decide what is urgent, and how to keep the rest for the morning.
Is out-of-hours work worth it for a sole trader?
It depends on three things you can measure: how many genuine emergencies you get, what you charge for them, and what the disruption costs you the next day. Plumbers on UK Plumbers Forums have debated this for years. One Leeds plumber's example bands were £50 for 8am to 6pm, £85 for 6pm to 11pm and £100 for 11pm to 8am, and the experienced replies were blunt: charge for all of your time, including travel, or the numbers do not work. (Those figures are from 2008, so treat the structure as the useful part, not the prices.)
Current price guides confirm the logic rather than a number. One 2026 guide notes that "a call out on Christmas Day or at 3am is likely to incur a larger call out fee than at a standard time on a weekday" (MyJobQuote, updated August 2026).
A useful test: if you would be annoyed to get the call at your current night rate, the rate is too low.
What are my options for cover?
| Option | What you offer | Good for | Downside |
|---|---|---|---|
| No out-of-hours | Daytime only; out-of-hours message gives next available slot | Plumbers with young families or full diaries | Some emergencies go to competitors |
| Evenings only | Up to, say, 10pm; overnight goes to the morning | A middle ground with less sleep disruption | Needs a clear cut-off |
| Existing customers only | Emergencies for people already on your books | Rewarding loyalty, fewer unknowns at night | Needs a reliable customer list |
| Full 24/7 | Any genuine emergency, any time | Building an emergency-led business | Hardest on health; needs strict pricing |
You can change your mind later. Starting with evenings or existing customers only tells you what the real demand is before you commit your nights.
How do I decide what counts as an emergency?
Write the rule down before the phone rings at 1am, when everything sounds urgent. A typical split for a water-only plumber:
Usually worth attending tonight
- Water escaping that the customer cannot stop
- Water coming through a ceiling or near electrics
- No water at all to a vulnerable household
- A blocked only toilet in a single-toilet home (your call)
Usually fine for the morning
- Dripping taps and slow leaks into a bucket
- Running toilets and noisy pipes
- Quotes, installs and general enquiries
- Anything the caller says "can wait"
Your list will differ. The point is that the decision is made once, by you, not at 1am by whoever answers.
Gas and electrical dangers are different. You should not be giving safety advice over the phone for those, and neither should anyone answering for you. In Great Britain, a caller who smells gas should be pointed to the National Gas Emergency Service on 0800 111 999, which is free and open 24 hours. To report a power cut in England, Scotland and Wales, the number is 105, and anyone with a life-threatening emergency should call 999 (GOV.UK Prepare).
Can a customer cancel an emergency job afterwards?
Generally not. Trading Standards' Business Companion guidance says there is no 14-day cancellation right where the consumer "specifically requested the trader to call to carry out urgent repairs or maintenance". That covers the emergency itself. If you also sell something extra while you are there, such as replacing a whole bathroom tap set, that additional sale can still carry the normal cancellation right, so keep it separate and offer to come back in hours.
What makes a night job hard to dispute is the same as by day: the customer agreed the price before you set off. Say the night rate on the phone, confirm it by text, and get on the road.
How do I stop every call waking me up?
This is where most sole traders give up on out-of-hours work. The calls are not the problem; the non-urgent ones are. Practical options:
- Price for self-selection. A clearly stated night rate makes many callers decide their drip can wait until 8am.
- Change your voicemail at night. Say what you cover, the night rate, and that non-urgent messages will be returned in the morning. Some callers will not leave a voicemail, though, and simply ring the next number.
- Use a missed-call text-back. A message to anyone you could not answer keeps them from ringing round.
- Have calls answered and filtered. A person or service answers, asks the questions on your list, and only puts through the ones that meet your rule.
Option 4 is what Remi does: it answers your line around the clock, puts urgent calls through to whoever is on call with a summary of who is calling and why, and takes a detailed message for everything else so you start the morning with a list rather than a voicemail inbox. If you want to see how that fits a plumbing business, here is the 24/7 answering set up for plumbers. It is not an emergency service, and it does not give safety advice; it gets the right calls to you.
A setup checklist
- Choose your cover option and write it on your website and Google profile.
- Set night and weekend rates, and test them against "would I be glad to go?"
- Write your emergency list (attend tonight vs morning).
- Note the official numbers: 0800 111 999 (gas, GB), 105 (power cuts in England, Scotland and Wales), 999 (danger to life).
- Decide who answers at night and how urgent calls reach you.
- Confirm the night rate by text before every out-of-hours visit.
The short version
Out-of-hours work pays for a sole trader plumber when the rate makes you glad to get up and you are only woken for genuine emergencies. Start with limited cover, write down what counts as urgent before the phone rings, and point gas or electrical dangers to the official numbers rather than advising. Emergency call-outs generally sit outside the 14-day cancellation right. The thing that makes or breaks it is filtering: decide who answers at night, and make sure the drip can wait until morning.
