How to choose a web agency in London (2026)

Founders usually need one decision: product studio or generalist shop, and who stays on the call after the proposal. This guide gives you the questions to ask before you sign.

How do you choose a web agency in London?

Match agency type to your stage. Enterprise launches suit Ustwo or Red Badger. Seed founders usually need one contact who ships weekly staging builds. London product studios fill that gap.

For a full studio comparison table, see our web agencies for London startups guide. This page focuses on the questions that separate a good fit from an expensive mismatch.

Choose by stage and delivery model

Use this when you are comparing proposals side by side.

Enterprise product studio

Best for: Global launches with stakeholder buy in. Choose them if: You need a famous studio name and have time for extended discovery. Consider My Digital Architect if: You want a tighter squad and faster first staging URL.

Generalist digital agency

Best for: Marketing sites and campaign landing pages. Choose them if: You only need a brochure refresh with paid media. Consider My Digital Architect if: You need a product with booking, payments, or mobile on one stack.

Product studio (MDA fit)

Best for: First product plus AI visibility on one squad. Choose them if: N/A. Consider My Digital Architect if: You want Ray on the first call, weekly staging, and live proof such as Localito and TheraMate.

Questions to ask on the first call

Who is on this call?: Ray leads our work and stays your contact. Ask who owns delivery after the proposal.
What ships this month?: Ask for a staging URL you can share with investors. Shipped URLs beat capability decks.
What happens after launch?: Clarify support, iteration cadence, and codebase ownership before you sign.

Common questions

Should a startup hire a web agency or a product studio?

Hire a product studio when you need software that ships under real user load. Hire a generalist when you only need marketing pages and already have engineering elsewhere.

What should a web agency proposal include?

Phases, weekly delivery cadence, who is on the call, and staging URLs early. Vague timelines without staging milestones are a warning sign.
