Out-of-hours and emergency calls: a guide for plumbers

Before you change anything on your phone, decide what you're actually offering. There are three honest positions:

• Full 24-hour emergency cover, at an emergency rate.
• Evenings and weekends, but not overnight.
• Daytime only, with every out-of-hours call taken down and returned first thing.

All three work. What doesn't work is leaving it undecided, so that every late call becomes a judgement made half asleep. Write your position down, along with your out-of-hours rates, because whoever answers your phone will need both.

Set your rules in advance, in plain words, so whoever answers can apply them the same way every time. A simple version:

Thames Water's advice for a burst pipe is to turn off the stop tap, usually found under the kitchen sink, by turning it clockwise, and to switch the electrics off at the mains if there is water near them (Thames Water). If you want your phone cover to pass that on, write it into your emergency instruction word for word.

For gas, the number is 0800 111 999 in Great Britain (National Gas) and 0800 002 001 in Northern Ireland (nidirect). Anyone describing an immediate danger to life should be told to call 999.

Rates vary by area and by business, but consumer price guides give a useful benchmark. Checkatrade's cost guide, last updated in June 2026, gives these UK averages (Checkatrade):

The same guide says emergency plumbers may charge up to twice their normal hourly rate, plus a call-out charge, which is common for out-of-hours and weekend work (Checkatrade). These are averages from a consumer site, not a price list, so set your own.

Whatever you charge, say it on the call. Telling the customer your call-out fee and hourly rate before you set off saves an argument on the doorstep. Give your phone cover the exact wording, including whether VAT is on top.

Most work you agree with a customer at their home is an "off-premises" contract under the Consumer Contracts Regulations 2013, and for most of those the customer has 14 days to cancel. Business Companion, the trading standards guidance for businesses, explains that you must usually give the customer information about you, the work, the price and their right to cancel before the contract is made (Business Companion).

Urgent repairs are treated differently. The cancellation rules don't apply where the customer has specifically asked you to visit to carry out urgent repairs or maintenance (Consumer Contracts Regulations 2013, regulation 28(1)(e)). But that exemption doesn't cover extra services, or goods other than the parts needed for the repair, that you supply on the same visit (regulation 28(2)).

In practice: the emergency repair itself is outside the cancellation rules, but if you quote for a new cylinder while you're there, that's a separate contract with the usual rights. If a customer wants non-urgent work to start straight away, Business Companion says they must confirm that in writing or by email (Business Companion). This is a summary, so check the guidance or take advice if you're unsure.

The worst outcome at night isn't a call you can't attend. It's a worried customer who reaches nothing and rings the next plumber. Even if you're not going out until morning, the caller should hear three things: that they've reached your business, what to do now, and when they'll hear from you.

A caller whose problem has been made safe, whose details have been taken and who has been given a time has a reason to wait for you. Silence or a full voicemail box gives them a reason to try someone else. Our guide to why customers ring the next trade looks at that in more detail.

If you have a team, an on-call rota spreads the load so nobody is always on. If you're on your own, answering every call yourself at 2am and working a full day after it won't last. These are the options:

Forward to your mobile and answer it yourself

Free and personal, but you're never off, and a missed call still ends up in voicemail.

A voicemail greeting that does the work

Say you're closed, give your emergency instruction and the gas number, and say when you'll call back. Free, but many callers still hang up.

A human answering service

A remote receptionist takes the call from your script and calls or texts you for emergencies. Good for callers who want a person. Out-of-hours cover is often charged extra, and most services bill per call or minute.

An AI receptionist

Answers every forwarded call in your business name, asks your questions, applies your emergency rules, gives your instructions and rates, and alerts you only when a call meets your rules for an emergency. Usually a flat monthly fee.

Every out-of-hours call should leave you with enough to act at 7am without ringing back to ask the basics:

1. 1Name, mobile number, address and postcode.
2. 2What's wrong, and whether the water is off.
3. 3Whether it met your emergency rules, and what the caller was told.
4. 4When they're free, or the time they were booked in for.

Confirm the routine jobs first thing, before the customer has a chance to ring round. That's how out-of-hours calls fill your diary instead of keeping you up.
