Marketing agencies in London — live B2B lead lists
Looking to sell to marketing agencies in London? This guide shows how to pull a complete, current list of them straight from Google Maps — every business name, phone number, website and, where it is published, an email address. London is home to roughly 8,900,000 residents, with its business base concentrated in districts like City of London, Westminster and Shoreditch, so the city rewards a structured, district-by-district search far more than one broad query. With a market the size of London, the single biggest lever is working district by district — Google Maps coverage is far more complete when each query targets one area instead of the whole city at once. Kavex turns that search into a downloadable CSV in under a minute, then enriches each row with a website-extracted email and deliverability scoring.
What you'll find scraping marketing agencies in London
London is vast — by population the largest city in this set by a wide margin — and no single search captures it. The City and Canary Wharf hold finance and professional services, Shoreditch and Soho concentrate creative and media firms, and everyday trades spread across all 32 boroughs. London also has its own vocabulary: estate agent rather than realtor, solicitor rather than lawyer.
For a category like marketing agencies, the count you get back depends entirely on how granular your search terms are: one broad query returns a slice, while splitting by district and sub-category can surface anywhere from a few dozen to well over a thousand businesses across London and its suburbs. Expect a little over half to list a website — the rest you can still reach by phone — with the central clusters falling in City of London and Westminster. The districts below are each worth a separate search:
- City of London
- Westminster
- Shoreditch
- Camden
- Canary Wharf
- Soho
The best way to search for London marketing agencies
Open the Google Maps scraper, set the country to the United Kingdom and the region to London. The setting that matters most is how granular each query is: search one sub-type or one district at a time rather than marketing agencies across all of London at once. Run the search one district at a time so each query stays under Google's ~120-result cap.
- Search borough by borough — London is far too large for a single city-wide query.
- Use British terms: estate agent, solicitor, GP surgery — they match more London listings than the US equivalents.
- London postcode districts (EC, WC, E1, SW1 and so on) are a precise way to split a search.
- The City and Canary Wharf are where corporate and financial-services businesses concentrate.

What the London marketing agency export looks like
Every job downloads as a CSV with one marketing agency per row. Each row carries the business name, full address, phone number, website, primary category, star rating and review count, with a website-extracted email added wherever one is published. The columns and the district spread you receive look like this:
- One row per business: name, address, phone, website, category, rating and review count.
- A central City of London marketing agency: phone and website both present, plus a website-extracted email.
- A Westminster listing: phone and website present, no public email — still reachable by phone.
- An outer-district marketing agency: phone only, ready for a Phone Validator pass before any call.
Enrich and personalise before you reach out
Toggle "Include emails" so the scraper visits each marketing agency website and extracts a contact address, then run those through the Email Verifier to drop anything undeliverable. For the businesses with no public email, the Phone Validator separates mobile from landline numbers. Finally, the AI Personalizer turns each row into a short cold email that references the business name and its London location — far stronger than a mail-merge blast.
