If you're choosing between a paper pad by the phone, a shared spreadsheet and a form on your website, use whichever the person taking messages will fill in every time, and give all three the same fields. An enquiry form template is only doing its job if someone who wasn't there can ring the customer back from it. Below are the ten fields to copy, extra questions for each trade, a filled-in example, and what UK data protection law expects when you take someone's details.
The form works for plumbers, heating engineers, electricians, roofers, builders and joiners, whether one person answers every call or a partner takes messages while you're on the tools. For the routine around it, from who owns each callback to closing out the day, see how to stop missing calls and book more of your enquiries.
Pick the format your team will fill in
There's no single right format. The right one is the one that gets filled in when you're busy, cold or up a ladder. Most small firms end up using two: a paper pad or phone notes for calls, and a web form that lands in a shared inbox.
| Format | Suits | Watch out for |
|---|---|---|
| Paper pad by the phone | One office person, or a partner at home taking calls | Only one person can see it, and it can't be searched later |
| Shared spreadsheet | Two or three people who all need to see open enquiries | Needs a phone signal to update from site, and access must be limited to the people who need it |
| Website form | Customers who'd rather type than ring, often in the evening | Must go to an inbox more than one person checks, or it's a voicemail no one plays |
| Job management app | Firms already using one for jobs and quotes | Check the enquiry screen has every field below before you rely on it |
Whichever you choose, use the same fields in the same order. Then a call written on a pad and a web form typed at 10pm can go into one list, and anyone can pick up the callback.
If you start on paper and move to a spreadsheet or an app later, keep the field order the same. The people taking messages won't have to learn a new form, and you can compare the old pads with the new records to see whether anything gets missed after the change. Start with the simplest format that works, and only move on when it stops coping.
If the person taking messages will be an answering service, give them the same form. The guide to call answering services, AI receptionists and missed-call texts covers how to hand it over.
Ten fields for every enquiry form
The form below holds the ten things most trade firms need to call a customer back and book the right visit: when and how the enquiry came in, the customer’s name and number, the job address, who they are, the problem in their words, anything urgent, whether it’s a new or existing job, who owns the callback, and each attempt. Print it for the desk, or copy it into your phone, a spreadsheet or your job app.
That's enough. Every extra field is one more thing to skip when the phone rings at 7am. If you need more detail for a quote, ask on the callback or at the visit.
Keep in mind that every field is personal data. The ICO, the UK's data protection regulator, says personal data must be adequate, relevant and limited to what is necessary, and that you must not collect it on the off-chance it might be useful in the future. So no date of birth, no copy of a tenancy agreement and no card numbers on the form. If a customer wants to pay a deposit, take it through your payment system, not on the enquiry sheet.
Write the problem in the customer's words
The most useful field on the form is also the one most often filled in badly. The person taking the message is tempted to translate what the customer said into a diagnosis: "diverter valve" instead of "no hot water, heating works", or "RCD" instead of "power keeps going off in the kitchen".

Write what the customer says, in their words, even if you think you know the answer. There are three reasons.
First, the guess may be wrong, and the engineer turns up with the wrong part. Second, the customer remembers what they told you. If the quote or invoice says something different, it starts an argument. Third, whoever makes the callback can ask the right follow-up questions only if they know what the customer said.
Add what the customer has already tried, if they mention it: "turned the stopcock off", "reset the trip twice", "put a bucket under it". It tells you how urgent it is and stops the engineer suggesting something that's already been done.
If the customer has sent photos by text or WhatsApp, note that on the form, with where they were sent. A photo of a boiler's data plate or a damp patch saves a lot of questions, but only if the person making the callback knows it exists.
Get texts, WhatsApp and voicemails onto the form
Calls are only one way enquiries arrive. A text at 6am, a WhatsApp message with three photos, a voicemail left while you were driving, an email to an address only one person reads: each is an enquiry, and each needs the same ten fields written down in the same place.
The risk with messages is that they feel handled because you've read them. You see the WhatsApp, mean to reply after the job, and by the evening it's buried under twenty other chats. Reading a message isn't the same as logging it.
Make it a rule that every message that could be work goes onto the form when you first read it, even if all you can write is the name, the number and "WhatsApp, leak under sink, photos sent". Then reply with a short message saying when you'll call. The form is the list you work from; the phone is just where the message landed.
Voicemails need one extra step. Play them in full, write down the number the caller gives rather than relying on the caller ID, and note the time they called, not the time you listened. A voicemail left at 7.05am and played at 12.30pm is a customer who has been waiting five hours.
If two people share the business phone, agree who logs messages at which times of day. Otherwise both assume the other one has done it.
Extra questions for each trade
The ten fields work for every trade. On top of them, a few questions specific to the work help you send the right person with the right kit, or decide whether you need to visit before you can quote. These are suggestions to adapt, not a script.
| Trade | Ask | Why it helps |
|---|---|---|
| Heating and plumbing | Boiler make, roughly how old it is, and whether it shows a fault code | Tells you whether a part is likely to be in stock or needs ordering |
| Electrical | Is it the whole property or one circuit, and has anything tripped | Separates a quick visit from a fault-finding job |
| Roofing | Which part of the roof, and is it one storey or two | Tells you what access equipment to bring |
| Building and joinery | Rough size of the job, and is there a drawing or a planning reference | Tells you whether to visit first or ask for photos |
| Any trade, rented property | Who approves the work and who pays | Avoids doing work the landlord or agent won't pay for |
Ask these on the callback rather than the first contact, unless the customer is already explaining it. The first contact is about getting a name, a number and the problem down before the phone goes again.
None of these questions involves telling the customer how to fix anything. If a customer asks what to do in the meantime, keep to simple safety steps you're sure of and leave the diagnosis for the visit.
Put urgent enquiries at the top
An enquiry form is also a way to make sure an emergency isn't treated as a routine callback. Give the "anything urgent" field a box that stands out: a tick box at the top of a paper pad, a highlighted column in a spreadsheet, or a question near the start of a web form.
Decide in advance what counts as urgent for your business, and write it on the pad or above the form. For a plumber it might be water coming through a ceiling or no water at all. For a heating engineer it might be no heating or hot water. For an electrician it might be no power or a burning smell. Write the list down so the person taking messages doesn't have to judge it alone.
If a caller mentions a smell of gas or suspected carbon monoxide, the call routine in the Calls hub covers what to tell them first. Put that line at the top of the form so it's the first thing anyone taking a call sees.
Urgent doesn't mean you promise to come today. It means the callback happens first, and the customer gets a straight answer about when someone can get there.
Example form: a Saturday ceiling leak
This is an invented example to show the form filled in. A plumbing firm run by two people takes a call at 9.40am on a Saturday. The owner is on a job, so his partner takes it at home on the business mobile and writes it on the enquiry pad.
Illustrative example: a ceiling leak on a Saturday
Received: Saturday 9.40am, phone call
Customer: Mrs Shah (name and mobile number recorded), free to talk any time today
Job address: postcode recorded; flat above is also hers, let to a tenant
Who they are: homeowner and landlord of the upstairs flat
Problem in her words: water dripping through the kitchen ceiling from the bathroom above, started this morning
Already tried: tenant has turned the water off at the stopcock; bucket under the drip
Urgent: yes, water coming through a ceiling
New or existing: new enquiry
Owner and callback due: owner, by 11am, partner to text if he can't
Status: callback due; 9.45am text sent saying he'll ring by 11am
At 10.20am the owner finishes the job he's on, reads the pad photo his partner sent him, and rings Mrs Shah. Because the form says the water is off and who the tenant is, he doesn't need to ask any of that again. He books a visit for 12.30pm, updates the status to "booked", and the enquiry record becomes the brief for the visit. Our job sheet template for trade visits picks up from there.
Keep website enquiry forms short
A website form is an enquiry form the customer fills in themselves, so the same rule applies: ask only what you need to call them back. Long forms with drop-down menus for boiler models and a dozen required fields put people off, and you'll ask most of it on the phone anyway.
A short web form needs:
- Name.
- Phone number, and a choice of call, text or email for the reply.
- Postcode of the job.
- "What's the problem?" as a free text box.
- An optional photo upload.
- One short line about how you'll use their details, with a link to your privacy notice.
Make the form send to an inbox at least two people check, and add it to whatever routine you use to close out the day. The free call handling checklist includes checking the form inbox before you finish. Send a quick reply giving a time for the callback, so the customer knows the form worked.
Tell people what you'll do with their details
When you collect someone's details, the ICO says you must give them privacy information at the time you collect the data. That includes who you are and how to contact you, why you're using their details, your lawful basis, how long you'll keep them, who you'll share them with, and what rights they have. The ICO says it should be concise, clear and in plain language.

For a small trade firm, that usually means a short privacy notice on your website, and a way to point people to it:
- On a web form: one line above the submit button, such as "We'll use these details to reply to your enquiry and arrange a visit. Our privacy notice explains how long we keep them and your rights," with a link. - On the phone: if the customer asks, tell them you'll use their details to arrange the job and that your privacy notice is on your website. Put the address on your quotes and job confirmations too. - On paper: the pad stays in the office and is kept with your other records, not left in the van.
How long to keep enquiries that never became jobs is your decision, but you should be able to explain it. The Calls hub covers keeping only what you need, and for how long.
The ICO says its guidance on these points is under review following the Data (Use and Access) Act, so check the links before you rely on them.
Marketing tick boxes and health details
Two things on an enquiry form need more care than the rest.
A marketing tick box. If you'd like to send customers offers or service reminders later, you might add a box asking if they'd like to hear from you. The ICO says silence, pre-ticked boxes or inactivity should not count as consent, and that a consent request should be separate from other terms. So the box starts unticked, it's optional, and the form still sends if it's left blank. Messages about the enquiry itself, such as your callback and the quote, aren't marketing. Our quote follow-up messages explain where a follow-up turns into marketing.
Health details. Customers sometimes explain why a job is urgent with a medical reason. The ICO says health information is special category data, which needs extra protection, and that you must identify a further condition before you use it. On most enquiry forms you don't need the medical detail to book the job. Write what changes the job, such as "urgent: no heating, customer at home all day", and leave out the diagnosis.
This is not legal advice. It summarises the ICO guidance linked above. UK data protection law applies in England, Wales, Scotland and Northern Ireland alike.
Put your form by the phone today
Copy the ten fields onto a pad, a spreadsheet or your job app before the phone goes tomorrow morning, and add the urgent list at the top. At the end of the week, read back through the forms and see which fields were left blank. Those are the questions to ask on every call from now on.
Count what you miss, then price the visit
