About OnTheMarket
Learn what OnTheMarket offers and what valuable data can be extracted from it.
Marketplace Overview
OnTheMarket is a premier UK property portal, launched in 2015 and currently majority-owned by the CoStar Group. It serves as a vital platform for estate agents to list residential and commercial properties for sale and rent across the United Kingdom. The site is a primary competitor to Rightmove and Zoopla, distinguished by its unique listing terms.
Data Availability
The platform hosts a massive repository of structured real estate information, including asking prices, detailed property specifications, high-resolution imagery, and floor plans. A significant feature is the "Only With Us" label, where properties appear on OnTheMarket 24 hours or more before being listed on other major portals, providing a distinct time advantage for data collection.
Scraping Potential
For real estate professionals and investors, scraping this platform is highly valuable for market analysis and trend tracking. Accessing this data at scale allows for the creation of automated valuation models (AVMs), competitive inventory monitoring, and the identification of motivated sellers through price drop detection without manual effort.

import requests
from bs4 import BeautifulSoup
# OnTheMarket uses Cloudflare; standard requests often get 403 Forbidden

print(f'Price: {price} | Address: {address}')
except Exception as e:
print(f'Scraping failed: {e}')When to Use

- ●Lowest resource consumption
- ●Easy to parallelize with asyncio
- ●Great for APIs and static pages
Limitations
- ●Cannot execute JavaScript
- ●Fails on SPAs and dynamic content
- ●May struggle with complex anti-bot systems
