CP12 records are only part of the paperwork burden on a gas engineering firm. Boiler service records, commissioning forms, breakdown visit reports, and annual safety checks each carry their own documentation requirements. This guide is for small gas engineering firms that are still doing most of it on paper.
Most discussions about gas engineer software focus on the CP12. But a gas engineering firm running 5-15 engineers produces several distinct types of field records, each with different content requirements and different recipients.
The CP12. the annual landlord gas safety certificate. is the most legally significant. Its required fields are specified in regulation. It is one type among several.
A boiler service generates a service record: work done, readings taken, condition of components. This goes to the property owner or letting agent and supports the boiler warranty.
A commissioning visit generates a commissioning form. typically the manufacturer's own document. recording the initial gas rate, operating pressure, flue readings, and the engineer's confirmation that the installation meets manufacturer and Building Regulations requirements. A warranty condition and a Building Regulations compliance record.
A breakdown visit generates a visit report: fault diagnosis, parts replaced, work carried out, outcome. It goes to the customer and serves as both the engineering record and the invoice basis.
For landlord portfolios, there may also be pre-tenancy gas checks. interim inspections between annual checks, or checks required by a new mortgage lender.
A busy engineer might produce all five types in a single week. Most of them are currently completed in the van, from notes or memory, after the job is done.
The van-afterwards workflow is universal in gas engineering. It is so normal it has stopped being noticed as a problem.
Accuracy degrades between the boiler and the van. An engineer who took a flue CO reading of 42ppm at 11:15am and writes it up at 12:30pm after two more jobs has reasonable but not perfect recall. Most of the time the figure is right. Some of the time it is close. Occasionally it is wrong.
Volume compounds the problem. Six jobs means six forms. Each form has 20-40 fields. The engineer who starts completing them at 6pm is working from a notepad, phone photos, and memory. The last record of the day is reliably worse than the first.
Time pressure creates abbreviation. "Boiler serviced, satisfactory" is not a useful service record. It proves nothing was done wrong. It proves nothing was done at all. Engineers completing forms under pressure default to minimum entries.
None of this is a character failing. It is a predictable consequence of the wrong tool for the context.
Landlords with managed portfolios expect digital records delivered promptly after each visit. Letting agents managing 50+ properties want certificates and service records in their inbox the same day the job is done.
A gas engineering firm on a paper workflow cannot meet this reliably. The engineer completes the form in the van. The paper form goes in a folder. The firm director or office manager scans it when they get round to it. The landlord emails asking for the certificate two days later. Someone finds the folder, scans the form, and emails it.
This happens thousands of times a day across UK gas firms. But it is friction that accumulates. The letting agent who works with two gas firms. one that emails the certificate the same day, one that takes three days. forms a preference. Over a portfolio of 80 properties, that preference becomes a contract.
Digital records also allow landlords to check their own compliance status without calling the engineer. A landlord with 20 properties needs to know which are due for renewal before HSE asks. Paper cannot provide that.
New boiler commissioning is where gas engineering firms most often fall short of full documentation. The boiler manufacturer's commissioning form is a warranty document. without a completed commissioning record, the manufacturer's warranty may not be valid.
Commissioning forms require a large number of readings: gas rate, operating pressure, combustion analysis figures, flow and return temperatures, flue terminal location, system details. On a pressured installation day, with the customer present and the tiling contractor waiting, the commissioning form sometimes gets abbreviated or delayed.
A commissioning form completed correctly at the time of installation. readings captured as they are taken. is complete. A form completed from memory an hour later may have rounded figures, missing readings, or omissions. The manufacturer does not distinguish; both forms look identical. But in a warranty dispute the weakness shows.
Capturing commissioning data into a WhatsApp workflow as each reading is taken produces a timestamped record of every figure as it was found. The completed form generates from that record. The engineer does not need to rewrite anything.
Breakdown visit reports serve two purposes: the engineering record of what was found and fixed, and the basis for the invoice. A breakdown report that does not record the specific fault, the diagnosis, and the parts used is both an incomplete engineering record and a weak invoice justification.
Customers who query invoices expect to see what was done. "Labour and parts: £280" without a breakdown is harder to defend than a report that records "fault diagnosed: heat exchanger seal failed; replaced seal and expansion vessel; tested to operating pressure; combustion analysis satisfactory; system restored to service."
The engineer who captures that detail in the chat during the job. answering structured questions, or voice noting the fault and findings. produces a better record than the engineer who writes it up from memory in the van. Better for the customer. Better for the firm. Better in the event of a comeback.
Quickler runs each gas workflow type as a separate WhatsApp conversation, triggered by the engineer when they arrive on site or automatically by a scheduled message for planned visits.
The engineer answers structured questions in WhatsApp as they work through the job. Voice notes are transcribed automatically. an engineer who says "flue CO 38ppm, within tolerance" at the flue terminal has that reading captured in real time without breaking concentration.
When the workflow completes, the relevant document generates: CP12, service record, commissioning form, or breakdown report. The PDF exports from the dashboard. One-click email sends it to the landlord, letting agent, or customer.
The dashboard shows the status of every open and completed record across all engineers. Landlords can be given read-only access to view their own portfolio. Email alerts fire when a new record is ready.
One firm. One platform. All gas workflows. No separate logins, no per-seat billing, no new app. They are already in WhatsApp.
Gas engineers complete several distinct types of site records: CP12 gas safety certificates, boiler service records, commissioning forms for new installations, breakdown visit reports, gas tightness test records, and purging and pressure testing records. Each has different required content. All share the same problem. they are currently completed on paper or from memory after the job.
There is no statutory retention requirement for boiler service records in the way there is for CP12 certificates. Service records support warranty claims, justify the next service recommendation, and provide evidence of due diligence in the event of a breakdown dispute. Most gas engineering firms retain service records for at least 2-3 years.
Date and time of attendance, property address, customer or landlord details, appliance details (make, model, age), the fault found, work carried out, any parts replaced with part numbers, the outcome (resolved, temporary repair, appliance condemned), any further work required, and the engineer's name and Gas Safe registration number.
Voice recordings alone are not sufficient as a formal gas safety record. the Gas Safety (Installation and Use) Regulations 1998 require a written record with specific fields. Voice notes can be used as the input method if they are automatically transcribed into a structured record capturing all required fields. The resulting written record is legally compliant. The voice note is how the engineer provided the data.
CP12s, service records, commissioning forms, breakdown reports. Engineers capture data as they work. Records generate automatically.
