The CP12 gets all the attention. It is not the whole job. A gas firm running 5 to 15 engineers also churns out boiler service records, commissioning forms, and breakdown reports every week. Most of it is gas engineer paperwork uk firms still write up by hand, in the van, after the boiler is cold. The fix is not a fatter clipboard. It is gas engineer field reporting software that captures the record while the engineer is still at the appliance.

Replace gas paperwork in 2026.
CP12s are only part of the burden. Boiler service records, commissioning forms, and breakdown reports each carry their own paperwork. This guide is for small gas firms still doing most of it on paper.
Free forever: 20 reports a month. No card, no trial clock.
The real scope
More than the CP12.
A firm running 5-15 engineers produces several distinct field records: CP12 certificates, boiler service records, commissioning forms, and breakdown reports. A busy engineer might produce all of these in a single week. Most are completed in the van afterwards, from notes or memory once the job is done.
The root problem
In the van afterwards.
Accuracy degrades between the boiler and the van. Six jobs means six forms of 20-40 fields each, written up from a notepad, phone photos, and memory. Time pressure creates abbreviation. "Boiler serviced, satisfactory" proves nothing was done. It is the wrong tool for the context, not a character failing.
Where it bites
The records that suffer.
Commissioning
Warranty at risk
Without a complete commissioning record, the manufacturer's warranty may not be valid. Forms written from memory round figures or miss readings.
BreakdownsWeak invoices
A report missing the fault, diagnosis, and parts is both an incomplete engineering record and a weak invoice justification.
LandlordsLost contracts
Agents managing portfolios want certificates the same day. Paper workflows cannot meet that, and preference becomes contract.
One platform
All gas workflows in WhatsApp.
Engineers answer structured questions on site. Voice notes transcribe in real time. The PDF generates and emails to the landlord, agent, or customer. No separate logins, no per-seat billing, no new app.
The short version
- A gas engineer completing 6 jobs a day has 6 separate sets of paperwork to produce. Paper means doing it from memory in the van.
- Boiler service records, commissioning forms, and breakdown reports carry different required content but the same root problem.
- Landlords and letting agents expect digital records and same-day email. Paper workflows cannot meet that reliably.
- Voice notes captured during the job beat typing from memory afterwards, and a boiler service report software workflow keeps the timestamp.
- One WhatsApp platform covers CP12s, gas commissioning form uk records, and a gas breakdown report app uk firms can run with no extra logins.
- The Gas Safety (Installation and Use) Regulations 1998 still demand a written record with set fields, whatever the input method.
The real scope
More than the CP12
Most talk about gas engineer software fixes on the CP12. But a firm running 5 to 15 engineers produces several distinct field records, each with different content and different recipients.
The CP12, the annual landlord gas safety certificate, is the most legally significant. Its 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. It goes to the property owner or letting agent and supports the boiler warranty. A commissioning visit generates a commissioning form, usually the manufacturer's own document, recording initial gas rate, operating pressure, flue readings, and the engineer's confirmation that the install meets manufacturer and Building Regulations requirements. A breakdown visit generates a 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 are completed in the van, from notes or memory, once the job is already done.
The root problem
In the van afterwards
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 imperfect recall. Most of the time the figure is right. Some of the time it is close. Occasionally it is wrong.
Volume compounds it. Six jobs means six forms. Each form has 20 to 40 fields. The engineer who starts 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 breeds abbreviation. "Boiler serviced, satisfactory" proves nothing was done at all. None of this is a character failing. It is the predictable cost of the wrong tool for the context.
Where it bites
The landlord and agent problem
Landlords with managed portfolios expect digital records delivered promptly after each visit. Letting agents running 50-plus properties want certificates and service records in their inbox the same day the job is done.
A firm on a paper workflow cannot meet this reliably. The engineer completes the form in the van. The paper goes in a folder. The office manager scans it when they get round to it. The landlord emails two days later asking for the certificate. Someone finds the folder, scans the form, sends it. This happens thousands of times a day across UK gas firms.
It is friction, and friction accumulates. The agent who works with two gas firms, one that emails the certificate same day, one that takes three days, forms a preference. Over a portfolio of 80 properties, that preference becomes a contract. Digital records also let landlords check their own compliance status. A landlord with 20 properties needs to know which are due for renewal before HSE asks. Paper cannot provide that.
Warranty at risk
Commissioning forms, most often incomplete
New boiler commissioning is where firms most often fall short of full documentation. The manufacturer's commissioning form is a warranty document: without a completed commissioning record, the warranty may not be valid. A gas commissioning form uk engineers skip is a warranty they have quietly put at risk.
Commissioning forms demand a lot 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 to finish, the commissioning form sometimes gets abbreviated or delayed.
A form completed correctly at the time of installation, readings captured as they are taken, is complete. A form done from memory an hour later may carry rounded figures or missing readings. The manufacturer does not distinguish; both forms look identical until a warranty dispute exposes the weak one. Capturing the commissioning data into a WhatsApp workflow as each reading is taken produces a timestamped record of every figure exactly as it was found. The completed form generates from that record. The engineer does not need to rewrite anything.
The commercial record
Breakdown reports earn the invoice
Breakdown visit reports do two jobs: the engineering record of what was found and fixed, and the basis for the invoice. A report that omits the specific fault, the diagnosis, and the parts used is both an incomplete engineering record and a weak invoice justification. A gas breakdown report app uk firms actually use turns both around.
Customers who query invoices expect to see what was done. "Labour and parts: 280 pounds" is harder to defend than "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 one writing it up from memory in the van. Better for the customer. Better for the firm. Better in the event of a comeback.

How Quickler runs every gas workflow
Quickler runs each gas workflow type as a separate WhatsApp conversation, triggered by the engineer on arrival or automatically by a scheduled message for planned visits.
The engineer answers structured questions in WhatsApp as they work the job. Voice notes are transcribed automatically: an engineer who says "flue CO 38ppm, within tolerance" at the 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 their own portfolio. A landlord with 20 properties can see which are due for renewal before HSE asks. Email alerts fire the moment 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. See our CP12 gas safety software, CP12 report template, and digital signatures for field reports.
Questions, answered
What types of paperwork do gas engineers have to complete on site?
Gas engineers complete several distinct 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 done on paper or from memory after the job.
Do boiler service records have to be kept?
There is no statutory retention requirement for boiler service records the way there is for CP12 certificates. Service records still support warranty claims, justify the next service recommendation, and prove due diligence in a breakdown dispute. Most firms retain them for at least 2-3 years. Good boiler service report software keeps them searchable.
What should a gas breakdown visit report include?
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.
Can voice notes be used as gas engineering site records?
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 work as the input method if they are automatically transcribed into a structured record capturing every required field. The resulting written record is legally compliant. The voice note is simply how the engineer provided the data.
