The Quick Answer: If you have the copy and data finalized, 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
When UK startups look for pitch deck design, they often face extreme sticker shock. Specialized "fundraising agencies" charge exorbitant fees because they are pricing based on the value of the capital you are trying to raise, rather than the labor required to design the slides.
Agencies will bundle strategy, copywriting, and financial modeling into their fee. However, if you are a capable founder who already has a solid narrative and a rough draft in Google Slides, paying an agency £5k just to make it look good is a waste of your runway.
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 Visualization: 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: Applying a consistent, premium visual identity that subtly signals to investors that you are a high-value, organised operator.
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.
