Messaging in a regulated trade: what you can and cannot say by text

Most advice about automating a trade business is written as though every job is the same job. For anyone working on gas or on electrical installations, it is not. There are things you are legally required to be registered to do, things you must notify afterwards, and things you must never say to a customer over a message however reasonable the question sounds.

That does not make automation unsuitable. It makes the boundary the first thing to design rather than the last. Get it right and the rest of it, the enquiries, the reminders, the certificates, the chasing, works exactly as it does in any other trade.

The duties a message cannot satisfy

Start with what is fixed, because it sets the shape of everything else.

Gas work within the scope of the Gas Safety (Installation and Use) Regulations 1998 may only be carried out by a business on the Gas Safe Register. That is a legal requirement rather than a trade association preference, and it attaches to the business and to the competence categories the individual holds (HSE).

Where work is notifiable under the building regulations, a registered installer self-certifies it through a competent person scheme rather than going through building control. Those schemes cover heat-producing appliances and fixed electrical installations in dwellings, among other categories (GOV.UK), and each sets the period within which a completed job has to be notified.

Electrical work in dwellings has its own regime, with certain categories notifiable and installation work assessed against the wiring regulations. The details vary between nations, so check the position where you work rather than assuming the one you learned first still applies.

None of that changes because a customer prefers to communicate by message. Automation can schedule, remind, collect and deliver. It cannot perform a duty that attaches to a competent person.

The questions that must never be answered automatically

There is a category of message that arrives regularly and has exactly one correct handling.

Anything describing a gas smell. The answer is the recognised safety advice, immediately, and a person. Nothing else, and no attempt to establish how serious it sounds.

Anything describing a burning smell, sparking, or a repeatedly tripping circuit. Same treatment. These are not diagnostic conversations.

Carbon monoxide symptoms, particularly where somebody describes headaches or nausea that improve when they leave the house. This needs the standard advice and urgency, not a booking slot.

A customer asking whether something is safe to use. The only honest answer from an automated system is that it cannot say, followed by an escalation.

A customer asking how to do something themselves. Where the work is one that must be done by a registered person, the answer is that it must be, in plain words.

The rule underneath all of these: an automated exchange can ask, escalate and repeat published safety guidance. It cannot assess, reassure, or judge severity. A system that reassures a customer whose boiler is producing carbon monoxide has done something no efficiency gain could justify.

Build that boundary first and test it deliberately, with the wordings customers actually use rather than the ones you would use.

Identity, and the card the customer should ask for

Registered gas engineers carry an identity card showing a photograph, a registration number, an expiry date, and on the reverse the categories of work they are qualified to do. Consumers are encouraged to ask for it before any gas work is carried out (HSE).

Which is worth putting into your own messages rather than waiting to be asked. A confirmation that names the engineer who is coming, invites the customer to check the card, and says they can verify the business on the register, is reassuring rather than defensive. It also protects you, because impersonation of tradespeople is a real problem and a customer who expects to check is a customer who will not let somebody else in.

Include a photograph of the van or the engineer if that suits how you work. Elderly customers in particular find it genuinely useful.

What happens after the work

The paperwork is where regulated trades leak, and messaging is unusually good at this part.

A customer should leave the visit knowing what was done, what it cost, what any certificate or record covers, and what happens next if there is a follow-up. Sending that in writing at the door, rather than posting it later or promising to email it, closes the job properly.

Where a notification is required, it is yours to make and within the period the regulations set. It is exactly the kind of obligation that slips in a busy week, and exactly the kind a reminder handles well: the job record carries the date, the reminder fires, nobody has to remember.

Building it with CodeWords

CodeWords connects to more than 3,000 integrations, and the connection is made once and reused.

1. Open CodeWords and start a new automation.
2. Describe what should happen in plain language to Cody, the automation builder: the safety escalations first, then what is collected at enquiry, which confirmations go out, and what is reminded.
3. Authorize the connections to your calendar, wherever job records and certificates live, and your WhatsApp Business Platform account.
4. Describe the exceptions in detail, because in this trade the exceptions are the point: anything unsafe, anything requiring a registered person, a landlord property, a certificate due, a notification outstanding.
5. Test the safety escalations with real customer phrasing before turning any of it on, and keep testing them quarterly.

You describe the outcome; Cody builds it, connects it, and deploys it. The free plan covers light use, with Pro at $39 per month and Business at $100 per month as usage grows; details are on the pricing page.

Certificates and records, which customers lose

Every certificate you issue will be lost by somebody, usually at the moment it matters: a sale, a letting, an insurance claim, a new engineer asking what was done.

Sending it through a channel the customer keeps is a small kindness with a long tail. Keeping your own copy, retrievable by address rather than by customer name, is the part that saves you. Addresses persist; occupants do not, and a reissue request three years later usually comes from somebody whose name is not in your records.

Store them outside the messaging app. A thread on a handset is not a record-keeping system, and these are documents you may be asked for long after that phone has been replaced.

Landlords are a different customer

They behave differently and they need a different process.

The person paying is not the person on site, which changes access, authorisation and who receives the certificate.

They have recurring statutory duties with dates, which makes them the most automatable customer you have.

Certificates go to them and often to a tenant or an agent, and getting that distribution wrong causes an argument at the worst moment.

Access is the failure mode. Arranging with a tenant through a landlord is where visits get wasted, so confirm directly with whoever will be in.

A landlord whose annual dates you track and remind them about reliably is a customer who stops shopping around, because you are removing something they are anxious about.

Annual duties, which are a business in themselves

Regulated trades have something most businesses would pay for: work that recurs on a known date.

Every annual check you have done is next year's booking, and the list is the asset. Keep it by address, keep the dates accurate, and contact people before the anniversary with an offer of a slot rather than a notice.

Two details. Contact early enough that a failed check leaves time to remedy it, since a certificate that lapses while parts are on order is a problem for a landlord. And keep the list clean, because a property that changed hands generates a reminder to somebody who has no idea who you are.

What is safe to automate in a regulated trade

Enquiry intake, once the safety check sits in front of it.

Booking and confirmation, including who is attending and the card to ask for.

Arrival windows and delays.

Certificate delivery and re-sending on request.

Notification reminders to you, not to the customer.

Annual renewal reminders, which is the largest commercial opportunity here.

Invoices and payment.

Review requests, afterwards and once.

What stays with a person: anything about safety, anything about whether a system can be used, anything a customer is worried about, and every judgement about competence.

Making it survive

Test the safety escalations quarterly, with real phrasing.

Keep certificates outside the messaging app, filed by address.

Remind yourself about notifications, within the period your scheme sets.

Confirm access with whoever is actually in, not only with whoever booked.

Review the annual list monthly so lapsed dates surface before they matter.

Limits worth knowing about

Registration and competence cannot be delegated to software.

An automated message cannot judge whether something is safe, only escalate.

Notification duties are yours, whatever reminded you.

Requirements differ between nations, so check where you actually work.

Customers will ask for advice you cannot give by message, and the correct answer is often that it needs looking at.

What to build first

The safety escalation, and a test of it. Write down the phrasings customers actually use for a gas smell, a burning smell, a tripping circuit and feeling unwell at home, and make sure each one produces the published advice and a person within minutes. Nothing else here matters until that works.

Two habits make the difference. Keep certificates filed by address rather than by name, because the person asking in three years will not be the person you issued it to. And treat the annual renewal list as the commercial centre of the business, since it is the one thing in this trade that tells you what next year looks like.

Frequently asked questions

Can automation handle gas or electrical work enquiries?

Yes, for booking, confirmations, certificates, reminders and payment. It cannot assess safety, and the escalation for anything unsafe has to sit in front of everything else.

What must never be answered automatically?

Gas smells, burning smells, sparking or repeatedly tripping circuits, carbon monoxide symptoms, whether something is safe to use, and how to do notifiable work yourself. Each gets the published advice and a person.

Is Gas Safe registration a legal requirement?

Yes. Gas work within the scope of the Gas Safety (Installation and Use) Regulations 1998 may only be carried out by a business on the Gas Safe Register.

What happens after notifiable work is completed?

A registered installer self-certifies it through a competent person scheme rather than going through building control, within the period that scheme sets. That duty is yours regardless of what reminded you.

What should a booking confirmation include?

Who is attending, an invitation to ask for their identity card, and that the business can be checked on the register. Customers find it reassuring and it makes impersonation harder.

Where should certificates be stored?

Outside the messaging app, filed by address rather than by customer name, because the person requesting a copy years later is often a new occupant.

Why are landlords different?

The payer is not on site, they have recurring statutory duties with dates, certificates go to several parties, and access has to be confirmed with whoever is actually in.

What is the biggest commercial opportunity in a regulated trade?

The annual list. Every check done is next year's booking, on a known date, at a known address, which is a predictability most businesses do not have.

When should renewal reminders go out?

Early enough that a failed check leaves time to remedy it before the current certificate lapses, which matters most to landlords.

Do requirements differ across the UK?

Yes, particularly for electrical work and building regulations notification. Check the position where you actually work rather than assuming.
