Guernsey has a handful of established marketing agencies, and they differ most in what they lead with: PR, brand and design, social media and content, strategy, or paid ads and search. Hamilton Brooke describes itself as the island's largest full-service agency, TPA and The Potting Shed work across Guernsey and Jersey, and NWB and Digital Gorilla publish prices. Below is what each firm says it offers on its own website, checked on 11 November 2026. We are a Jersey agency that also works with Guernsey businesses and we are on the list, so we have stuck to what each firm publishes about itself.

Guernsey numbers worth knowing
Meta's advertising tools put Facebook ad reach in Guernsey at around 38,200 people and Instagram at around 25,400 in late 2025, and DataReportal counts around 54,000 internet users, about 84% of the population (Digital 2026: Guernsey). In a market that size, the same people see your ads again and again, so creative needs changing more often than in a big city. Our free ad reach tool narrows these figures to your own customers.
Guernsey also has its own data protection law, The Data Protection (Bailiwick of Guernsey) Law, 2017, overseen by the ODPA. Any agency running ads, forms or email for you should know it applies, rather than only UK GDPR.
Five questions to ask any agency
- What have you done for a Guernsey business like mine, in numbers?
- Who will actually do the work, and where are they based?
- What will you measure: enquiries and sales, or likes and reach?
- What do I own if we stop: the ad account, the website, the content?
- How much is your fee, and how much is ad spend, paid separately?
