What to say in a missed call text back: 15 proven templates for UK tradespeople (2026)
Updated August 202610 min readBy TextBack Pro
You are on a job. Your phone rings. You cannot answer. By the time you finish and check your phone, the customer has already called two other tradespeople. This is not bad luck. It is the most common way UK sole traders lose work, and it happens dozens of times every week.
The solution is not to answer every call. It is to send the right text back within seconds so the customer knows you are aware of them, that help is coming, and they do not need to keep dialling. This guide gives you 15 templates you can copy, customise, and use today, plus everything you need to know about wording, length, tone, and legality.

The anatomy of a perfect missed call SMS
A good missed call text back has four parts. Every template that converts well contains all of them. Leave one out and you lose either warmth, clarity, or the reason for the customer to wait.
The 4 parts of a high-converting missed call SMS
1
Greeting and identification
Tell the customer who you are immediately. They may not have your number saved.
"Hi, thanks for calling JH Plumbing."
2
Acknowledgement
Confirm you know they called and that it was not intentionally ignored.
"Sorry I missed your call, I am on a job right now."
3
Callback promise
Set a clear expectation. Vague promises ("I will call back") are less reassuring than specific ones.
"I will call you back as soon as I am free, likely within the hour."
4
Escape hatch for urgency
Let the customer flag if their issue cannot wait. This prevents them from going elsewhere for emergencies.
"If it is urgent, reply here and I will get to you sooner."
All four parts fit comfortably in 160 characters. The templates below are built on this framework and adjusted for different trades and situations.
Standard missed call templates
These five templates work for any UK trade and any situation. Start with one of these if you are setting up an automated reply for the first time.
Template 1: The standard (most popular)
Template 1 of 15
Best for: all trades, all situations, unknown callers
Hi, thanks for calling [Business Name]. Sorry I missed your call, I am on a job. I will call you back as soon as I am free. If it is urgent, reply here. [Your Name]
154 characters
The most tested template for UK tradespeople. Warm, honest, and gives the customer a clear next step. The "if urgent, reply here" line reduces silent lead loss for time-sensitive jobs.
Template 2: Short and direct
Template 2 of 15
Best for: returning customers, referred contacts, repeat work
Hi, sorry I missed you. I am on a job and will call you back shortly. [Business Name]
84 characters
Concise and no-nonsense. Works best when the customer already knows you, so a longer explanation is not needed. Also the safest choice if your work number receives a lot of supplier or trade calls alongside customer enquiries.
Template 3: With specific timing
Template 3 of 15
Best for: when you know roughly how long your current job will take
Hi, thanks for calling [Business Name]. Sorry I missed you. I am on a job until around [time] and will call you straight after. [Your Name]
137 characters (with example time)
Specific timing reduces anxiety. A customer who knows they will get a call at 2pm is far less likely to keep dialling than one who received a vague "I will call back soon."
Template 4: With reply invitation
Template 4 of 15
Best for: when you want to gather job details before calling back
Hi, thanks for calling [Business Name]. Sorry I missed your call. Feel free to drop a message here with what you need and I will call you back with a rough idea of costs. [Your Name]
178 characters (2 segments)
Converts a missed call into a pre-qualified lead. By the time you call back, you already know the scope of the job, which makes the conversation faster and more professional.
Template 5: With booking link
Template 5 of 15
Best for: Pro and Scale plan users with Google Calendar booking enabled
Hi, thanks for calling [Business Name]. Sorry I missed you. Book a callback at a time that suits you: [booking link]. Or I will call you as soon as I am free. [Your Name]
169 characters (2 segments with link)
Eliminates phone tag entirely. The customer picks a time, you get a calendar notification, and the conversation starts on time. TextBack Pro connects directly to your Google Calendar on the Pro and Scale plans.
Trade-specific templates
These five templates are tailored to specific trades and carry wording that reflects the nature of those jobs. Use the one that matches your trade and adjust the business name.
Template 6: Plumber
Template 6 of 15 / Plumber
Acknowledges that plumbing calls are often urgent
Hi, thanks for calling [Business Name] plumbing. Sorry I missed you. I am on a job right now. Reply here if you have a leak or urgent issue and I will prioritise you. Otherwise I will call you back shortly. [Your Name]
216 characters (2 segments)
Plumbing enquiries often involve genuine emergencies. This template gives customers a clear way to escalate without leaving them waiting anxiously for a callback.
Template 7: Gas engineer
Template 7 of 15 / Gas engineer
Includes the Gas Emergency Helpline for safety compliance
Hi, thanks for calling [Business Name]. Sorry I missed your call. I will call you back shortly. If you can smell gas or have a gas emergency, please call 0800 111 999 now. [Your Name]
182 characters (2 segments)
The 0800 111 999 National Gas Emergency Service number is the correct one to include. Including it is both responsible and professional. Never leave a gas customer with no safety escalation path.
Template 8: Electrician
Template 8 of 15 / Electrician
Handles electrical emergency triage without alarming the customer
Hi, thanks for calling [Business Name] electrical. Sorry I missed you. I am on a job. Reply here with a brief description and I will call you back as soon as I am free. [Your Name]
177 characters (2 segments)
Asking for a brief description pre-qualifies the lead (quote vs fault finding vs emergency) so you can triage before calling back. This saves time on both sides.
Template 9: Builder
Template 9 of 15 / Builder
Sets a realistic callback expectation for longer site days
Hi, thanks for calling [Business Name]. Sorry I missed your call. We are on site today and will call you back this afternoon. For anything urgent, reply here. [Your Name]
162 characters (2 segments)
"We are on site" signals a professional operation. Builders often have longer jobs where an immediate callback is not realistic. "This afternoon" is more credible than "shortly" for site-based tradespeople.
Template 10: Roofer
Template 10 of 15 / Roofer
Works well when working at height makes answering impossible
Hi, thanks for calling [Business Name] roofing. Sorry I missed you. I am working up on a roof right now. I will call you back when I am safely down. [Your Name]
152 characters
"When I am safely down" is honest, human, and immediately explains why you could not answer. Customers respond well to genuine explanations. It is also subtly reassuring that you take safety seriously on their job too.
Context-specific templates
These five templates handle situations that standard templates do not cover. Use them for evening calls, known referrals, post-quote follow-ups, or when a customer replies with their issue.
Template 11: Evening or out-of-hours call
Template 11 of 15
For calls received after 6pm or at weekends
Hi, thanks for calling [Business Name]. I have picked up your missed call. I am finished for the evening but will be in touch first thing tomorrow. Reply here if it is urgent. [Your Name]
183 characters (2 segments)
Shows the customer you are monitoring even out of hours. "First thing tomorrow" sets a clear expectation without over-promising. The opt-out for urgency ensures genuine emergencies are not lost overnight.
Template 12: Referral or known contact
Template 12 of 15
When you know or suspect the caller was referred to you
Hi, thanks for calling [Business Name]. Sorry I missed you. If [referrer name] sent you my way, I always look after their people well. I will call you back shortly. [Your Name]
174 characters (2 segments)
Referral warmth before the first conversation dramatically increases conversion. Most customers who were referred feel a stronger obligation to give you the job if you acknowledge the connection immediately.
Template 13: Quote follow-up
Template 13 of 15
When you have sent a quote and not heard back
Hi [Name], I sent over the quote for [job] last week and just missed your call. Happy to talk through anything or adjust the scope if needed. I will try you again shortly. [Your Name]
179 characters (2 segments)
Contextualises the missed call immediately. A customer who called about a pending quote does not want to explain themselves again. Showing you remember the job signals you are organised and attentive.
Template 14: Appointment reminder missed call
Template 14 of 15
When a customer may be calling about an upcoming booking
Hi [Name], I missed your call. If you are calling about your booking on [date], I have you confirmed. If anything has changed, just reply here and I will sort it. [Your Name]
168 characters (2 segments)
Handles the most common type of existing-customer call. If your booking is confirmed, say so. It saves both of you a phone call and signals that your operation is organised.
Template 15: After leaving a voicemail yourself
Template 15 of 15
When you have called the customer and left a voicemail, then they call back and you miss it again
Hi [Name], I just missed your call back. I left you a voicemail earlier about [topic]. Feel free to reply here or I will try you again at [time]. [Your Name]
155 characters
Breaks the phone tag loop. By acknowledging the context and offering a text-based reply, you give the customer an easy way to connect without playing the call-back game indefinitely.

What to say and what to avoid
Wording matters more than most tradespeople expect. A missed call SMS that sounds robotic or vague can actually lower your chances of winning the job compared to no SMS at all, because it signals that you do not take enquiries seriously.
Do say
Your business name in the first line
"I am on a job" (honest, relatable)
A specific callback time or window
"Reply here if urgent" (gives the customer control)
Your first name at the end
"Sorry I missed your call" (not "missed call detected")
An invitation to share details in text
Do not say
"Your call is important to us" (corporate cliche)
"We will be in touch shortly" (vague and impersonal)
"This is an automated message" (kills trust)
"[First Name]" (broken placeholder)
Your full terms and conditions
Two or more exclamation marks
Emoji in a first contact (use only in follow-ups)
Anything over 3 SMS segments (480 characters)
Length: one segment is the goal
An SMS segment is 160 characters when using standard GSM characters. Aim to fit your core message in one segment. If you need two, that is fine. Three or more starts to look like marketing copy rather than a personal reply. Use our free SMS template generator to see character counts for your personalised templates.
Tone: conversational, not corporate
The most effective missed call SMS sounds like it was sent by a human who happened to notice the missed call between jobs. "Hi, sorry I missed you, I am up a roof" will always outperform "Thank you for contacting ABC Contractors. A member of our team will be in contact at the earliest opportunity." Write how you speak.
TextBack Pro auto-personalises your template. The message includes your business name and can optionally include your first name, so it never looks like a copied-and-pasted text. Every reply goes to your phone as a normal SMS so you can continue the conversation naturally.

The wording of your SMS matters, but the timing matters even more. A perfectly worded SMS sent 3 hours later converts at roughly the same rate as a voicemail. The reason the instant reply wins is not clever copy. It is the fact that the customer is still thinking about their problem when the message arrives.
ROI: what the right wording is worth
Consider a plumber missing 6 calls per week at an average job value of £320. The table below compares four scenarios: no reply, a generic late manual SMS, a well-worded manual SMS, and an instant automated reply.

The wording upgrade alone (generic vs well-worded) is worth around £1,280 per month in this example. Adding instant delivery on top of good wording nearly doubles that again to £4,800. Both matter. Neither alone is as powerful as combining them.
GDPR: sending an automated SMS reply to a missed call
Sending an automated SMS in response to a missed call is fully compliant with UK GDPR. The caller initiated contact with your business number, which creates a legitimate interest for you to respond to that specific enquiry. You do not need prior consent to reply to an inbound enquiry.
Where the rules require more care is ongoing marketing after the initial enquiry is resolved. Sending a promotional offer six months after a one-off enquiry requires either legitimate interest (with a clear opt-out) or explicit consent captured at the time of the job.
Always identify your business name in the message.
Make it easy to opt out of further automated messages (a reply of STOP should be honoured).
Keep records of opt-outs and action them immediately.
Do not add missed call callers to a marketing list without their explicit consent.
TextBack Pro handles opt-out compliance automatically. When a customer replies STOP, their number is suppressed immediately and no further automated messages are sent from your account to that number.
Frequently asked questions
What should a missed call text back say?
A good missed call text back should identify your business, acknowledge the missed call warmly, set a clear expectation for when you will call back, and give the customer an option to flag urgency. Keep it under 160 characters if possible. Avoid corporate-sounding language and never let it sound like an automated system message.
How long should a missed call SMS reply be?
Under 160 characters for a single SMS segment. Up to 320 characters (2 segments) is acceptable when you need to include a booking link, job context, or safety number. Anything longer starts to feel like marketing copy rather than a personal reply and reduces open-to-response rates.
Is it legal to send an automated SMS reply to a missed call in the UK?
Yes. Responding to an inbound missed call with an automated SMS is lawful under UK GDPR as legitimate interest. The person chose to call you, creating a clear expectation of business contact. You must identify your business and make opting out straightforward. Ongoing marketing to the same number without consent is a separate matter and requires more care.
Should I use the customer's name in a missed call SMS?
Only if you have it. If the caller's number matches a saved contact, using their first name adds warmth. For unknown callers, a general greeting is perfectly fine. Never use a placeholder like [First Name] in an outgoing message. A visibly broken template does more damage to trust than a generic greeting.
What is the best time to send a missed call text back?
Immediately. Harvard Business Review research shows that responding within 5 minutes makes you 21 times more likely to convert the lead than responding after 30 minutes. An automated reply fired within seconds of the missed call is the most effective approach. Waiting to send the text manually is significantly less effective even if the wording is excellent.
