After Hours Answering Service For Plumbing And Trades
It’s ten to eleven on a Sunday. One caller has water coming through a ceiling, one has no hot water but working radiators, and one wants a price for a new boiler because they’ve been at work all week. One of those needs a van tonight. One of them is worth three grand.
We build after-hours answering for plumbing, heating, electrical and roofing firms that tells them apart and stops the quote calls going to whoever picked up first.

An after hours answering service for trades answers your phone outside working hours and decides which callers need a van tonight. Genuine emergencies — uncontrolled water, no heat in freezing weather, a live electrical fault — reach your on-call engineer with the address and the fault. Suspected gas goes straight to the emergency line, never to your diary. Quotes and everything else are captured properly for the morning. The point is not answering the phone. It is knowing which of those three calls is worth getting dressed for.
Which out-of-hours calls are worth a van tonight?
Every call after six comes down to two questions: does this need someone tonight, and is this worth money in the morning?
Get the first one wrong in one direction and you’re out at 1am for a dripping tap, you’ve lost the night, and the customer argues about the emergency rate when they see how small the job was.
Get it wrong the other way and water runs through a property until morning. The Association of British Insurers reported on 19 February 2026 that insurers paid almost £3.4 billion across more than 560,000 home insurance claims in 2025, with the average claim up 15% year on year to £6,000. Burst pipes and escape of water are among the largest categories.
The second question is the one nobody talks about. The emergency is a callout. The boiler replacement enquiry that rings at eight on a Tuesday is three or four thousand pounds, and that caller is ringing three firms and booking whoever answers.
Most firms handle both with a mobile diverted to the van. It rings while you’re under a sink, or at dinner, or asleep, and you decide in four seconds whether it’s worth it.
That isn’t triage. It’s a coin toss with your evening on one side and three grand on the other.

What comes in after six
Genuine emergencies
Uncontrolled water, no heat in freezing weather with someone vulnerable in the house, a live electrical fault, sewage backing up. The agent recognises these, reaches your on-call engineer with the address, the fault and whether the customer has found the stopcock, and confirms the handover landed rather than assuming it did.
Urgent, but morning will do
No hot water with the heating still running, a boiler locked out that resets, a leak contained in a bucket, one cold radiator. Logged as first job in the morning, with the customer told a time rather than left wondering.
Quotes and new work
Boiler replacements, rewires, bathrooms, a roof someone noticed after the storm. Captured with the detail you’d want before you price it — property type, age of the system, access, when they need it — and in your inbox before you’re up. This is the call that pays for the service.
Everything else that rings
Suppliers, chasing an invoice, a customer confirming Tuesday, someone who wants a part number. Captured properly: who called, what they wanted, what happens next. At 7am rather than as nine missed calls you work through in the van.
Built From Your Callouts, Not Our Template
Where your emergency rules come from
Not from us. We start with what you actually drove out to over the last six to twelve months, and which of those you’d take again.
Your Callout History
Most firms have a rough sense of how many night calls they get and are wrong about it, usually low.
Before we build anything we go through what actually happened — the ones you drove to, the ones you talked through on the phone, and the quote calls you never rang back.
That review is worth having on its own. It usually shows how many callouts you’d have priced differently, and how many enquiries went to someone else because you were on another job.

What We Look At
What We Map
What it won’t touch
It won’t take a gas leak as a job
A suspected gas escape is not a callout, it’s an emergency service call. The agent tells the caller to leave the gas alone, ventilate, and ring the National Gas Emergency Service on 0800 111 999 in the UK or their utility’s emergency line in the US — then logs it and tells you. It doesn’t book it, and it doesn’t send you. Only a Gas Safe registered engineer works on gas, and the network operator gets there first.
It won’t make a judgement we haven’t agreed
If a caller describes something outside the scenarios we’ve mapped, it escalates rather than guessing. That means the occasional call you’d rather it had held until morning. In a trade where the wrong answer floods a house, that’s the correct failure direction.
It won’t price a job
It captures what you need to price one and it can quote your published callout rate if you want it to. It won’t estimate a boiler swap over the phone at midnight, because you wouldn’t either, and a number given at 11pm is a number you’re held to at 8am.
It won’t fix a diary nobody updates
If the enquiry lands in your inbox at 7am and still hasn’t been rung back on Thursday, this surfaces that rather than solving it. More than one client has found the answering was never the problem — what happened to the message afterwards was.
How we get it live
Week one – mapping
We go through your out-of-hours calls: what comes in, what you actually attended, what you’d charge for it. This usually surfaces things you didn’t know, like how many quote enquiries arrived after six and never got a call back.
Week two – build and test
We build the agent, connect it to your job management or diary system, and test it against real calls from your own history rather than invented ones. You sign off the emergency wording and the gas hand-off before it answers anything.
Week three – live, watched.
It goes live with every call reviewed. We tune the rules on what actually comes in, because the first fortnight always turns up a caller nobody scripted for.
Weeks four to eight – optimising against real calls.
This is where the agent gets genuinely good. We listen to live calls and refine against the situations nobody predicted: the caller who says it’s not urgent about a live leak, the one who describes the fault three different ways, the accent the agent keeps mishearing.
Thresholds get adjusted where they’re sending you out too often or not often enough. Most of the difference between an agent that works and one that frustrates people is made in this window, not at build.

Most firms we speak to are comparing this against three things: diverting the phone to the van, a traditional answering service, or letting it ring out.
Diverting To The Van
Real cost if: you count the enquiries you never rang back. Most firms don’t, because they never knew about them.
A Traditional Answering Service
Real cost if: you’re paying per call and still making every callout decision yourself.
Mapped To Your Callouts
Good fit if: one missed boiler enquiry a month costs more than this does.
Frequently asked questions
How does it know which engineer to call?
From the rules we map with you — by trade, by postcode, by who’s on call that night, however you actually run it. If the first engineer doesn’t answer, it follows the fallback chain rather than stopping.
What happens if someone reports a gas smell?
It doesn’t treat it as a job. The caller is told to ventilate, avoid switches and naked flames, and ring the National Gas Emergency Service on 0800 111 999 — or their utility’s emergency number in the US. You get told immediately, but the gas network attends, not you. Northern Gas Networks aims to reach uncontrolled escapes within an hour.
Can it book jobs straight into the diary?
Yes, where you want it to. Most firms let it book routine work and morning-after visits directly, and hold emergencies for a human to confirm the engineer is actually going. That split is yours to set.
Will it quote my emergency callout rate?
If you want it to. Plenty of firms have it state the published callout charge so nobody arrives surprised, and leave everything else to be priced properly in daylight. It won’t invent a price for a job it hasn’t seen.
Can it be live before the first cold snap?
Around three weeks to go live, then four to eight weeks of tuning against real calls. Start in September and you’re tuned before the first freeze; start in December and you’re learning during your busiest fortnight of the year.
Do callers know they’re talking to AI?
If they ask, yes. We don’t build agents that claim to be human — and on an emergency line, a caller who thinks they’ve been fobbed off by a machine pretending otherwise rings the next firm.
