The brief
Three requests between 2023 and 2026, each building on the last.
We delivered the logo in June 2023 and the business cards that followed it in August 2023. In 2026 the business came to us to have work mats made, and the logo files and card artwork were rebuilt for that.
The approach
Flame and water in one badge
The logo brings a flame and a water drop together in a single mark. The flame runs in a warm gradient from gold at the tips to orange at the base, with a blue drop inside it. Two fine blue rings form a badge around it, with THAT BOILER arched across the top and GUY set along the bottom in the same warm orange as the flame.
The badge gives the mark one fixed, round outline, which keeps it tidy wherever it goes: centred on a card, on a work shirt or on a mat. We delivered it in June 2023 as a full set of files, and that same month the vector version went to a printer for workwear.
A business card in the same colours
We sent initial designs, and the one chosen puts the logo in the middle of a black card, framed by corner shapes in the same yellow and orange as the flame. On black, the gold to orange of the flame is the brightest thing on the card, so the logo is the first thing anyone sees.
Under the logo, the lines For all your plumbing and heating needs and Boiler repair specialist are set in condensed capitals, with the Gas Safe Register and Instagram marks beneath them. The reverse carries the contact details and a QR code that opens the business's Checkatrade profile, so a customer holding the card is one scan from its reviews. It is not shown here because it carries personal contact details.
Files rebuilt for work mats
In 2026 we rebuilt the logo file set so the mat maker and any card printer could work from the same artwork. The card was supplied as a print-ready PDF with 3 mm of bleed and the trim set exactly, outlined as vector on two pages, front and back, so it prints without needing any fonts installed.
The deliverables
LogoVector files in AI, EPS and PDF, with transparent and solid background PNGs, delivered June 2023. Presentation mockups showed the mark on black, on white and in a plant room.
Business card85 x 55 mm on a 91 x 61 mm page, 3 mm bleed on every side, outlined vector in two pages (front and back). Made in August 2023.
2026 file setAI, EPS and PDF, a cropped SVG, and PNG and JPG versions on transparent, white and black backgrounds at 3000 pixels square.
Trade context
General trade background, and what this project did about it.
Boiler engineers are listed on the Gas Safe Register, so a boiler engineer's card and van carry two brands: their own, and the Gas Safe Register mark. The That Boiler Guy card sets the Gas Safe Register and Instagram marks beneath the slogan, so the logo leads and the registration is still there to check.
Trade branding lives on workwear, vans, mats and cards as much as on a website. A round badge with a fixed outline centres on a card, embroiders on a shirt and sits square on a mat, which is how the same mark could go from cards and workwear in 2023 to mats in 2026.
Questions about this project
Why combine a flame and a water drop?
The business is a boiler repair specialist that takes on plumbing and heating work of every kind. A flame with a blue drop inside it shows heat and water in a single mark, and the two badge rings hold them together as one round shape.
Why is the card black?
It was the design chosen from the initial options we sent. The black lets the warm gradient of the flame and the yellow and orange corners carry the card, with the slogan and trade marks set quietly underneath.
Can the same files be used for workwear and mats?
Yes. The vector files scale to any size without losing sharpness, which is why the vector version went to a workwear printer in 2023, and why the 2026 set adds SVG and large PNG and JPG versions on transparent, white and black backgrounds.
