The verdict in three sentences
A London B2B startup raising its first round needs a clear, fast, credible site of 5 to 12 pages, which costs roughly 1,500 to 12,000 GBP depending on who builds it. A specialist SaaS studio at 15,000 to 40,000 GBP plus VAT makes sense once positioning is stable and the website becomes a measured acquisition channel, usually around Series A. Always add recurring costs to the build price: CRM, consent management, maintenance and content often match the build cost within two years.
What buyers and investors look for
A B2B buyer decides in about 30 seconds whether you solve their problem, whether anyone credible already uses you, and how to start (demo, trial, pricing). Investors want the same clarity plus team and traction. That means a homepage, one page per use case, a pricing or book a demo page, a team page, and forms wired into your CRM. Investor specific content (a short company overview, press, contact for the round) can live on one discreet page rather than a separate site.

Mini case study
Illustrative example: Priya, founder of a London startup selling compliance software to mid sized logistics firms, is preparing a 1.2 million GBP seed round. A specialist studio quotes 22,000 GBP plus VAT. She instead takes a remote premium build at about 1,700 GBP, adds 1,500 GBP of CRM integration and 30 GBP a month for consent management, plus 65 GBP a month maintenance. Over two years that is 1,700 + 1,500 + 720 + 1,560 = 5,480 GBP. The 16,520 GBP difference covers roughly three months of a junior account executive, which moves her traction metrics far more than a richer homepage.
