Print & Livery for Gas Engineers
The sticker on the boiler is next year’s booking
One printed item with a measurable return
A power flush is £615. A gas meter relocation, £425. An emergency gas repair, £255. A hob and oven connection, £255. An appliance service, £125.
Most print is impossible to attribute. You put a van on the road, work comes in, and nobody can say which was which.
There is one exception in your trade and it sits on the front of every boiler you touch.
A service sticker carrying your name, your number, the date of the visit and the date the next one is due does something no other printed item does: it is read at the exact moment the customer is thinking about the thing you sell. Every time the pressure drops, every time the heating plays up, every time a new owner or a tenant looks at the boiler and wonders who services it, your name is the one on it.
Two hundred service customers at £125 is £25,000 a year, and almost all of it depends on being remembered twelve months after a forty-minute visit. A sticker costing a few pence is one of the two or three mechanisms that makes that happen — the other being the reminder, which it reinforces rather than replaces.
Everything else worth printing, and the order
The service sticker. Weatherproof vinyl, five hundred for roughly £60 to £100. Dated, with next-due, your number and your registration. Highest return on this page.
A landlord certificate wallet. Agents file gas safety records for years. A printed wallet with your details on the outside sits in a compliance folder being seen by whoever opens it.
Photo ID cards. Around £5 to £15 each. Yours is the trade where a customer has been told, correctly, never to let an unverified person near the gas. Offering ID before it is asked for is worth more here than in any other trade on this site.
Workwear. Embroidered polos at £12 to £18, softshell at £30 to £45, setup £25 to £40. Uniform matters at the doorstep for the same reason ID does.
Vehicle livery. Cut vinyl at £350 to £700 or a wrap at £1,800 to £3,000. Your van is parked on a driveway for an hour, so it is a reassurance item as much as an advertising one — the neighbour sees a marked vehicle at a house they know.
A “what your service included” leave-behind. Customers do not know what they are paying £125 for and some suspect it is very little. A printed checklist of what was actually done makes the price make sense and makes skipping next year feel careless.
The ratio
Our Seen package is £29 a month — £348 a year. That is under three appliance services.
On the sticker alone: five hundred at around £80 is sixteen pence each, sitting on a boiler for a year in front of a customer worth £125 annually. If it holds even five additional rebookings across those five hundred houses, it has returned £625 against £80, and that is before the callouts and replacements that come from being the name on the appliance.
What we’d actually produce
A dated service sticker, designed to stay legible in an airing cupboard for twelve months and to be filled in reliably in thirty seconds.
A certificate wallet for landlord work, aimed at the agent’s filing cabinet.
ID cards and workwear as one set, so the doorstep moment is consistent whoever attends.
Van livery specified for a driveway, close and static rather than at speed.
The service checklist leave-behind, which defends the price and prompts the rebooking at the same time.
What good looks like at twelve months
- A dated sticker on every appliance you have touched this year
- Certificates going to agents in a wallet rather than loose
- ID offered at the door rather than produced on request
- A checklist left behind on every service
- A rebooking rate you can see, which is the number this trade lives on
The mistakes we see most
No sticker, or an undated one. Without the next-due date it is decoration; with it, it is a reminder that lives in the house all year.
Spending first on a wrap. The van is seen for an hour a job. The sticker is seen for a year.
No ID. In a safety trade this is the cheapest reassurance available and it is routinely skipped.
Nothing left behind after a service. The customer has no idea what was done, which makes £125 look like forty minutes of standing about.
The first ninety days
Weeks 1–4. Stickers and the service checklist, because they are quick to produce and start working on the next job you attend.
Weeks 5–8. ID cards, workwear and the certificate wallet, which together sort out the doorstep and the agent’s filing cabinet.
Weeks 9–12. Van livery, specified to match everything already in circulation.
At ninety days the measure is whether every appliance you have serviced this quarter carries a dated sticker with your number on it.
Where this lands in Gaffer
Every completed service schedules next year’s reminder, so the date written on the sticker and the date the system prompts on are the same date rather than two guesses.
Landlord certificates carry a hard expiry, which is what the printed wallet is holding — the paperwork an agent files matches the schedule you are working to.
And because job records show what was actually checked, the printed leave-behind describes the visit that happened rather than a generic list.
Two documents at one visit, because two people are involved
Landlord work has a print requirement that domestic work does not, and getting it wrong quietly costs you the relationship.
At a rental property there are two people with a stake in the visit and only one of them is standing in front of you. The tenant lets you in, watches you work and forms an opinion. The landlord or the managing agent pays the invoice, files the certificate and decides whether you come back to the other properties.
So two things get left, deliberately.
The tenant gets a short plain sheet: what was checked today, anything found, what to do if the heating stops, and who to ring. It takes a few seconds to hand over and it prevents the most common friction in rental work, which is a tenant reporting a fault to an agent who then rings you having heard a garbled version of what happened.
The landlord or agent gets the certificate in a wallet with the next-due date on the outside, plus anything that needs quoting for. That is the document that goes into a compliance file and gets looked at when the renewal comes round in eleven months.
Same visit, two audiences, two pieces of paper. It costs pence, it takes a minute, and it is the difference between servicing one flat and servicing a portfolio.
Questions gas engineers ask
Does a sticker really change the rebooking rate? It is one of the few print items with a directly observable effect, because it is read at the moment the customer thinks about heating.
Should the sticker carry my registration number? Yes, alongside the date. It invites the customer to check you, which is exactly the impression you want.
Is workwear necessary for a one-man business? At the doorstep, yes. It is the difference between an expected engineer and a stranger.
What about the landlord side? The wallet and the certificate presentation do the work there. Agents judge contractors substantially on paperwork.
