Complete Guide to Finding Real Estate Companies in London (2026)

London's property market is the densest commercial real estate cluster in Europe, with thousands of agencies, developers, and investment firms packed into 32 boroughs. If you sell PropTech, mortgage products, conveyancing software, or B2B services to estate agents, this is one of the highest-value lists you can build in 2026. The challenge is filtering signal from noise: thousands of one-person sole-trader brokers, hundreds of branch offices for the same brand, and a long tail of buy-to-let landlords listed as "real estate."

This guide walks you through the directories, filters, and verification tools that actually work in London, plus a complete walkthrough of using Tomba Reveal to pull a verified list in under an hour.

Key takeaways#

• London has roughly 22,000 active property businesses across Greater London, but only ~3,500 fit a typical "agency or developer with 5+ staff" ICP.
• Free directories (Rightmove, Zoopla, On The Market) give you company names but no decision-maker emails — you need an enrichment layer.
• Tomba Reveal lets you filter by keywords like real estate, property, agency plus city, and exports verified emails for outreach.
• A mixed approach (directories for discovery + Tomba for contacts + LinkedIn for personalization) beats any single tool.
• Verify before sending: London agency staff turnover runs 25-30% annually, so a six-month-old list is mostly stale.

Why find real estate companies in London?#

London is home to the headquarters of the UK's largest agency networks (Foxtons, Savills, Knight Frank, Hamptons, Dexters, Winkworth) and a long tail of independent boutique agencies clustered around Mayfair, Chelsea, Canary Wharf, and the City. The borough of Westminster alone holds more chartered surveyor firms than most European countries.

For B2B sellers, the math is unusually attractive. Average agency ACVs for software hover between £3,000 and £25,000, decision cycles are short (4-8 weeks for sub-£10k deals), and the buying committee is small — usually a managing director, a head of sales, and an IT lead. The same dynamics make London a brutal market for cold outreach: London estate agents receive 30-50 cold pitches per week, so your list quality and personalization matter more than volume.

You can sanity-check market size against the London Chamber of Commerce member directory and Companies House, which lets you filter active companies by SIC code 68310 (Real estate agencies) and 68320 (Management of real estate).

How to find real estate companies in London in 3 steps#

The fastest reliable workflow is a three-layer funnel: discover companies, enrich with contact data, then verify before sending.

Step 1 — Build a raw company list. Pull from at least two sources to catch the long tail. Start with Companies House for active SIC 68310/68320 firms registered in London postcodes, then layer Rightmove's "Find an agent" directory for branch-level granularity. Export to a spreadsheet with columns for company name, website, postcode, and number of listings (a rough proxy for size).

Step 2 — Enrich with decision-maker contacts. This is where most workflows stall, because directories rarely expose personal emails. Run the cleaned company-domain list through Tomba's bulk email finder or the domain search, which returns every confirmed email on a domain along with the job title attached to each address. For a list of 500 London agency websites, this typically yields 1,800-3,000 verified contacts.

Step 3 — Verify before sending. London agency staff churn is steep, so even a fresh-looking list needs a final pass through an email verifier to drop catch-all traps and abandoned aliases. Skipping this step is the single biggest cause of below-1% reply rates on London prospecting campaigns.

Using Tomba Reveal to filter by industry and city#

If you'd rather skip the directory-scraping step entirely, Tomba's website visitor reveal lets you query companies by free-text keywords plus location. For London real estate, the search that consistently produces the cleanest list uses three keywords joined with commas.

Open Tomba Reveal and set the following:

• Keywords: real estate, property, agency — the comma-separated values are OR-matched against company descriptions, meta tags, and homepage content, so a firm tagged "luxury property" and another tagged "commercial real estate agency" both show up.
• Location: London, United Kingdom.
• Optional filters: employee headcount (10-200 captures most independent and mid-size firms), tech stack (e.g., companies using Reapit or Alto CRM signal an active digital buyer), and traffic tier.

A typical run returns 600-1,200 companies. From there, export to CSV, push the domains into the bulk email finder, and you have a verified contact list in roughly 30 minutes of active work. If you're targeting individuals rather than companies, the LinkedIn finder maps LinkedIn URLs to work emails in the same flow.

Top directories and competitor tools#

You will get a denser list by combining a directory (for breadth) with a B2B platform (for contact data). Here's how Tomba Reveal stacks up against the three platforms most commonly used for London property prospecting.

A few practical notes from running this stack on real London campaigns:

• Sales Navigator is unbeatable for personalization signals (job changes, promotions, recent posts) but you still need a separate tool to extract emails. Pair it with Tomba's LinkedIn finder.
• Apollo is fine if your ICP skews toward larger US-headquartered firms with London offices, but for genuinely UK-domiciled independents (the bulk of the market), the data goes stale fast.
• ZoomInfo is overkill unless you're selling six-figure enterprise contracts to Savills, Knight Frank, or JLL — and even then, the contract minimums push most teams toward lighter-weight alternatives.
• For free-tier sanity checks, use Crunchbase to confirm funding status on PropTech-adjacent agencies before pitching.

You can also dig through specialized UK directories: the Royal Institution of Chartered Surveyors (RICS) member finder, the Propertymark member list for ARLA/NAEA-accredited agencies, and the London-specific Mayfair Agents directory for prime central listings.

Best outreach playbook once you have the list#

A verified list is half the job. The other half is sending something an agency principal will actually read. London estate agents are pitched constantly by mortgage brokers, CRM vendors, lead-gen services, and AI tools — your message needs to land in the first six seconds.

1. Segment by firm shape, not by size. A 4-person Mayfair lettings boutique and a 4-person Hackney sales agency have nothing in common. Split your list at least three ways: prime central (sales-heavy, high ACV), suburban (lettings-heavy, volume-driven), and commercial (slow-moving, RFP-driven).

2. Reference local proof. "We work with [neighboring agency in the same borough]" outperforms "we work with [global brand]" by roughly 3x in our internal tests. London property is hyperlocal — a Fulham agency cares far more about what Knight Frank Fulham is doing than what Knight Frank Singapore is doing.

3. Time the send. Tuesday-Thursday, 8:30-9:15 BST. Estate agents triage inbox during the morning coffee window before viewings start; afternoons are dead.

4. Verify deliverability infrastructure. Before launching, run your sending domain through a blacklist checker and confirm SPF/DKIM/DMARC alignment. London agency mail servers (mostly Microsoft 365 and Google Workspace) are aggressive on unauthenticated mail.

5. Keep the first message under 90 words. Lead with the local proof, name the problem in one sentence, propose a 15-minute call. No attachments, no calendars, no images.

6. Follow up four times. Industry response rate on email 1 sits around 4-7%; total response across a 4-touch sequence runs 18-24%. Track open and reply rates per segment so you can kill underperforming variants fast.

FAQ#

How many real estate companies are in London?#

Companies House lists roughly 22,000 active firms under SIC 68310 and 68320 across Greater London as of early 2026. After filtering out dormant entities, sole-trader buy-to-let landlords, and overseas-domiciled shells, the realistic addressable market for a B2B seller is around 3,500-5,000 firms.

What's the best way to find decision-maker emails at London agencies?#

A two-step flow works best: pull a clean domain list from Tomba Reveal or a directory, then run the domains through Tomba's domain search or bulk finder. For founder-led boutique agencies, the public Companies House director record gives you the name, and Tomba's email finder fills in the work email from there.

Can I scrape Rightmove or Zoopla directly?#

Both have terms of service prohibiting automated scraping, and both employ aggressive bot detection. For company-level discovery, use the public agent search interface manually or buy a licensed data feed. For contact enrichment, work from the agency website domains you've gathered rather than from the listing portals themselves.

How much does it cost to build a London real estate prospect list?#

Cost depends entirely on volume and verification depth. A 1,000-contact verified list using Tomba's Growth plan ($99/month per the Tomba pricing page) plus a few hours of cleanup runs around £80-120 in software cost. The same list built manually from Companies House and LinkedIn takes 20-30 hours of labor.

How often should I refresh a London real estate list?#

Every 90 days at most. London agency staff turnover sits at 25-30% per year, so a list left untouched for six months will have 10-15% hard bounces and another 10% role-change soft signals. Re-running the list through an email verifier quarterly is the cheapest insurance against deliverability damage.
