The short version: If you have the copy and data finalised, hiring a UK designer to visually polish a 12 to 15-slide pitch deck will cost a fixed price between £300 and £800. If you go to a startup branding agency for the exact same work, expect quotes starting at £2,000.
The agency vs. freelance pricing gap
Specialised "fundraising agencies" price off the value of the capital you're trying to raise, not the work required to design the slides. That's where the sticker shock comes from.
Agencies bundle strategy, copywriting, and financial modelling into that fee. If you already have a solid narrative and a rough draft in Google Slides, you're paying thousands for the one part you didn't need bundled.
What a pitch deck designer actually does
A good slide designer focuses on cognitive load. Investors skim decks in under three minutes; if a slide takes more than 10 seconds to understand, they skip it.
- Data visualisation: Converting boring bullet points or messy Excel tables into clean, instantly readable charts and infographics.
- Information hierarchy: Stripping out unnecessary words and using typography to draw the eye directly to your traction and market size.
- Brand authority: A consistent visual identity across every slide, so the deck reads as the work of an organised operator rather than a rush job.
How to get a fixed price
To avoid hourly scope creep, you must do the heavy lifting before handing the deck to a designer. The copy must be final. Do not ask a designer to "fill in the blanks" for your Go-To-Market strategy.
Send them the raw text, your logo files, and clearly state how many slides are in the deck. With HELYI's one-off graphic design service, I provide clear, fixed pricing based on the slide count, delivering a polished, investor-ready PDF without the agency markup.
