Text message templates for plumbers, builders and electricians
A trade-specific SMS template pack for UK plumbers, builders and electricians - the universal templates that work for every trade, the plumber-specific emergency call-out and gas-safe wording, the builder-specific multi-stage and weather-delay messages, and the electrician-specific NICEIC and EICR templates - all tuned for SMS length and tone.
WhatsApp is the default trade-customer channel for under-60s in the UK. SMS is the default for over-60s, customers without smartphones, and the messages where you specifically want the customer to read it within the hour (SMS still has a higher open rate than any other channel - 98% within 3 minutes). The two channels share most templates but have different conventions: SMS is shorter, has no read receipts visible to you, costs money per message in some setups, and reads more formally than WhatsApp.
This article is the SMS counterpart to the WhatsApp templates piece. Same six message types covered in the channel-agnostic hub, but tuned for SMS register and length. Plus three trade-specific sections covering the messages plumbers, builders, and electricians send most often - emergency call-out replies, gas-safe and Part P references, weather delays and stage-payment nudges, EICR booking and NICEIC certificate-ready messages.
Pick the universal templates as your default, then layer the trade-specific ones in for the moments they cover. Save the lot as quick-message templates in your phone or trade CRM so each send takes two taps rather than thirty seconds of typing.
SMS conventions that differ from WhatsApp
SMS reads slightly more formal than WhatsApp in UK trade context because the channel skews older and has no chat-bubble informality. Same brevity rule, slightly less casual tone. Watch the character count if you are sending from a paid bulk-SMS service - 160 characters fits one SMS segment, 161+ counts as two.
- Length - aim for under 160 characters where possible to keep cost down and reading time short. Most trade SMS templates fit in 80-120 chars; the full-text alternatives in this article are noted with character counts.
- Tone - slightly more formal than WhatsApp. "Hi [name]" instead of just "Hey". Full sentences rather than fragments. No emojis (some older phones strip them or display them as squares).
- Signature - include your name OR your business name at the end. SMS does not show a contact card the way WhatsApp does. "Hi John, on my way - ETA about 9.45. See you shortly. Andy from AcmePlumb." The signature is essential on first contact; can drop on continuing thread.
- No read receipts - you cannot see whether the customer has read the SMS. Plan chasing on a longer cadence than WhatsApp (e.g. day-7 for first chase rather than day-3). The customer cannot use "I never saw it" as an excuse if you keep the SMS log, though.
- Cost - personal SMS is usually free on UK monthly contracts; bulk-SMS services charge 3-6p per message. If sending via your trade CRM bulk SMS, factor cost into how many follow-ups you set up automatically.
Six universal SMS templates - all trades
These six templates work for every UK trade. Adapt the figures, dates, and trade-specific words; keep the structure and length. The character count is shown for each so you can stay within one SMS segment where it matters.
- On-the-way text (114 chars) - "Hi John, on my way - ETA about 9.45. Will park on the road if that's OK. See you shortly. Andy from AcmePlumb."
- Running late (132 chars) - "Hi John, traffic's heavier than I thought - looking at 9.20 now rather than 9.00, apologies. Will be there as quick as I can. Andy."
- Quote follow-up day 7 (137 chars) - "Hi John, just a quick check - did the quote for the [job] land OK last week? No rush, just let me know either way when you can. Andy."
- Invoice send confirmation (140 chars) - "Invoice on the way to your email - INV-2026-0142 for £1,840. Bank details on it, use the invoice number as the reference. Cheers, Andy."
- Day-7 invoice nudge (138 chars) - "Hi John, just a quick nudge on the invoice from last Tuesday - any chance you can settle that this week? Cheers, Andy from AcmePlumb."
- Review ask (148 chars) - "Hi John, glad it all turned out well. Big favour - mind sticking a quick Google review on for me? [link] No pressure if not. Thanks, Andy."
Plumber-specific SMS templates
Plumbing customers send the most urgent texts of any trade (leaks, no hot water, broken boilers on Friday night). The plumber-specific templates below handle the moments WhatsApp does not - emergency call-out triage, gas-safe certificate notifications, boiler service annual reminders. Each one is tuned for the plumber-customer rhythm of UK domestic work.
- Emergency call-out reply (149 chars) - "Hi [name], got your message - sorry to hear about the [leak/no heating]. Can be with you in about 45 minutes if you confirm the address. Andy AcmePlumb."
- Triage question if not urgent (147 chars) - "Hi [name], thanks for the message. Is water still coming through, or have you isolated it at the stop tap? That changes how fast I need to get there. Andy."
- Boiler service annual reminder (158 chars) - "Hi [name], it will have been 12 months since I serviced the boiler at [address]. Want me to book the annual service in? Roughly 1.5 hrs, £85 inc. Andy AcmePlumb."
- Gas-safe certificate ready (158 chars) - "Hi [name], gas safety certificate for the work at [address] is registered with Gas Safe Register and on the way to your email. Reference [number]. Cheers, Andy."
- Same-day reschedule (Gas Safe emergency on vulnerable customer) (158 chars) - "Hi [name], really sorry - vulnerable customer Gas Safe emergency just come in, have to attend. Can we move yours to Thurs morning? Will knock something off. Andy."
- Materials lead-time heads-up (156 chars) - "Hi [name], the Worcester Bosch part needed for your boiler is on a 3-4 day lead time. Will book the fit for next Tues if that works for you? Cheers, Andy AcmePlumb."
Builder-specific SMS templates
Building work runs over weeks not hours, so builder-customer SMS rhythm is different. The messages below handle the moments that define builder relationships: weather delays, stage-payment reminders, mid-job variation flags, end-of-day site stops. Multi-day jobs need more proactive comms than single-day jobs, and SMS works well for the brief status updates that build trust over a long project.
- Weather delay (158 chars) - "Hi [name], weather forecast looking properly wet tomorrow - happy to push the roof work to Thurs which is set to be dry, rather than half-day in the rain? Andy."
- Stage-payment reminder (159 chars) - "Hi [name], we have hit stage 2 (walls and roof complete) so the £6,800 stage payment is due. Invoice on the way to your email - bank details on it. Cheers, Andy."
- Variation on-site flag (157 chars) - "Hi [name], opened up the floor and found rot in the joists - need to replace 3 before going further. Adds about £420 and half a day. Photo coming. Reply YES to crack on."
- End-of-day site stop (147 chars) - "Hi [name], calling it for today - made good progress, on track for end-of-week. Will be back tomorrow at 8am. Anything you need to know, just text. Andy."
- Next-stage start (154 chars) - "Hi [name], stage 3 (openings + bi-fold doors) starts tomorrow Tues morning. Should take 6 working days. Delivery of the doors confirmed for Tuesday 9am. Andy."
- Snagging walk-round invite (150 chars) - "Hi [name], all done from my side - want to do a walk-round of the finished work together tomorrow at 4? Then I will sort any snags before invoicing. Andy."
Electrician-specific SMS templates
Electrician-customer SMS leans heavily on certification and compliance. The templates below cover the most common moments - emergency call-outs (no power, sparking), EICR booking and result notifications, Part P compliance for notifiable work, and the consumer-unit-upgrade booking flow. Electrical SMS reads slightly more technical than other trade SMS because the work is regulated and customers expect specifics.
- Emergency call-out reply (159 chars) - "Hi [name], got your message - no power can't wait. Can be with you in about 30 mins if address is confirmed. Make sure all appliances are off in meantime. Mike."
- EICR booking (157 chars) - "Hi [name], can do the EICR on Wed 23rd, takes about 2-3 hours, £165 incl certificate. Need to be in the property during - you OK to be there? Mike NICEIC."
- EICR satisfactory result (158 chars) - "Hi [name], EICR at [address] complete - rated satisfactory, no remedial works needed. Certificate on the way to your email. Cheers, Mike NICEIC reg [number]."
- EICR unsatisfactory + remedial quote (159 chars) - "Hi [name], EICR complete - some C2/C3 codes found. Will email the report and a remedial quote tomorrow. Nothing dangerous now but worth addressing soon. Mike."
- Consumer-unit upgrade booking (158 chars) - "Hi [name], consumer unit upgrade booked for Tues 5th. Power off for about 4 hours - 9.30 to 1.30. Fridge OK if door stays closed. Notifiable to LABC. Mike NICEIC."
- Part P notification confirmation (157 chars) - "Hi [name], Part P notification for the [job] submitted to LABC and confirmed - building control certificate will reach you direct in 2-3 weeks. Mike NICEIC."
Setup tips - getting the most from SMS as a UK tradesperson
SMS templates work best when they are one-tap-to-send and the right one is easy to find. The four setup tips below cover the common SMS-trade gotchas and how to avoid them.
- Save templates in your phone's native SMS app - both iOS (Text Replacement under Keyboard settings) and Android (Quick Replies in most SMS apps) support saved snippets. Type a shortcode (e.g. "/onmyway") and the template expands. Two-tap send.
- For bulk SMS (more than ~50 customers a month) - use a service like Textmagic, Esendex, or a trade CRM with built-in SMS. Costs ~3-6p per message but adds delivery receipts, scheduling, and audit trails personal phone SMS does not have.
- Group SMS gotcha - if you reply to a group message thread from a personal iPhone, your reply may go to the whole group. Always start a fresh thread for each customer to avoid the "reply-all" mistake on the day you have to mention a variation cost.
- CMA messaging routes SMS through the client record - so the message lives against the job, the audit trail stays attached for variation approvals, and the customer's reply lands in the same thread regardless of channel. See the trade-specific pages for /for-plumbers, /for-builders, and /for-electricians for how the CMA SMS workflow fits each trade.

Preguntas frecuentes
When should I send a text message to a customer instead of WhatsApp?
Three times. First - when the customer is over 60 or you do not know if they use WhatsApp; SMS is the safest default. Second - when you specifically want them to read it within the hour; SMS has a 98% open rate within 3 minutes vs WhatsApp's 70% within the hour. Third - when the customer first contacted you by phone call rather than WhatsApp; reply on the channel they used. WhatsApp is the better default for under-60s who messaged you on WhatsApp first.
How long should a customer text message be for a UK trade business?
Under 160 characters where possible to stay within one SMS segment and reduce reading time. Most trade SMS templates fit 80-120 chars; the on-the-way text is 114 chars, the day-7 invoice nudge is 138 chars. Two-paragraph SMS reads as work-spam to most customers; one short paragraph is the right length. If you need more, send a follow-up SMS rather than one long one.
What SMS templates should every UK tradesperson have saved?
Six universal templates: on-the-way, running late, quote follow-up day 7, invoice send confirmation, day-7 invoice nudge, review ask. Plus six trade-specific templates for your trade - plumbers need emergency call-out and gas-safe certificate; builders need weather delay, stage-payment, variation flag, end-of-day stop; electricians need EICR booking + result, consumer-unit upgrade, Part P confirmation. Saved as iOS Text Replacements or Android Quick Replies, each send takes two taps.
How is SMS different from WhatsApp for customer messaging?
Three things. SMS reads slightly more formal because the channel skews older. SMS has no read receipts visible to the sender, so chasing has to run on a longer cadence (day-7 for first chase rather than day-3). SMS costs money per message if sent via a bulk service (3-6p each), so factor cost into automated follow-up cadence. The conventions: include your name or business name at the end (SMS does not show a contact card), keep under 160 chars, no emojis (some older phones strip them).
Should I use a bulk SMS service or send from my personal phone?
Personal phone for under ~50 customer messages a month - cost is zero on UK monthly contracts. Bulk SMS service (Textmagic, Esendex, or a trade CRM with built-in SMS) for over ~50 a month - adds delivery receipts, scheduling, audit trails, and group-send capability. The pivot point is usually around the 5-engineer crew size. Always check the group-SMS gotcha - on personal iPhones, replying to a group thread can send to everyone, which is the kind of mistake you only make once with a variation cost message.
