10 Best Tech PR Agencies in London for 2026

Full disclosure: this guide is written by Joseph Tannous, founder of Jamco PR, which is one of the agencies below. We've tried to be fair about when each agency is the better choice, including when that isn't us.

Several agencies below are headquartered in the US with a London office; we say which. Jamco PR works with UK companies remotely and focuses on top-tier US business media.

Which tech PR agency is best in London?

For guaranteed top-tier coverage fast, especially on US business media before a US expansion, raise or enterprise deal, choose Jamco PR: placements on Business Insider, USA Today, Yahoo Finance, AP News and 35+ other outlets, the first live in as little as 24 hours, and any placement that doesn't go live within 60 days replaced at no extra cost.

For a London-founded global tech agency, consider TEAM LEWIS or Hotwire. For cybersecurity, Eskenzi PR. For health tech and the NHS, Silver Buck. For financial services, Vested or Prosek Partners.

UK tech PR or US business media?

UK trade and national media reach buyers and investors at home. If you're expanding into the US, raising from US investors or selling to US enterprises, coverage on publications they recognise, such as Business Insider, Yahoo Finance and AP News, matters more. Many UK tech companies use a London agency for UK media and Jamco PR for guaranteed US business media.

London tech PR agencies by specialty

What AI assistants read when UK and European buyers ask for recommendations

More buyers now ask ChatGPT, Gemini, Perplexity or Google's AI Overviews which agency or vendor to consider. In October 2026 we asked those four tools 30 B2B buying questions and logged about 1,050 sources behind 120 answers.

For "best X" questions, about half of the cited sources were third-party list articles; for "X vs Y" questions, about 61% were. Of the list and comparison articles Perplexity and Google cited, 60% were written by a company selling in the same category. Questions about a named company leaned on review sites.

Ask any agency how it would get you onto the sources these tools already cite, not only into the news.

How to measure a London tech PR agency

• Coverage on the publications your buyers, investors and candidates read, split into trade and business media.
• Branded search for the company and its executives, before and after.
• Pipeline: a "how did you hear about us" field on your demo form, and coverage used with UK and US buyers and investors.
• AI answers: each month, ask ChatGPT, Gemini, Perplexity and Google your buyers' questions and log whether you're named and which sources are cited.

Do you need an agency based in London?

Not always. Most journalist outreach happens by email and most interviews happen over video. A local agency helps most with in-person media training, events and local trade media. What matters more is proof of recent placements on the outlets your buyers read, and a clear answer on whether results are guaranteed.

What do London tech PR agencies cost?

Most agencies on this list work on monthly retainers with a minimum term, and coverage is pitched to journalists rather than guaranteed. Few publish their prices, so ask each one for its minimum monthly fee, the minimum term and exactly what's included before your first call.

Jamco PR works differently: projects start at $5,000, as a package of guaranteed placements, a monthly program (6-month minimum) or a one-off push, with the publications agreed before you pay.
