Why You Shouldn't Rely on Rightmove Alone
Rightmove is the UK's biggest property portal. It has the most traffic, the most listings, and it is where most renters start their search. But biggest does not mean complete.
Every major UK property portal has listings that the others don't. Some agents list on Zoopla but not Rightmove. Some landlords advertise directly on OpenRent and nowhere else. OnTheMarket offers early access to certain listings before they appear on rival portals. And if you are looking for a room in a shared house, SpareRoom has an entire inventory of flatshare listings that no other portal carries.
For renters in competitive cities — London, Manchester, Birmingham, Bristol — missing even a handful of listings can mean missing your next home. The best rental properties attract dozens of enquiries within hours. If a property was listed on a portal you weren't checking, you never had a chance.
The Best Rightmove Alternatives for UK Renters
Zoopla
Zoopla is the UK's second-largest property portal, with an estimated 55 million monthly visits and strong coverage across both sales and lettings. It is owned by Houseful (formerly ZPG Ltd), which also operates PrimeLocation.
What Zoopla does well:
- Strong letting agent partnerships, particularly with larger agency chains
- Travel Time Search lets you search by commute time to a specific workplace or station
- Area guides with local data on transport, schools, and demographics
- Running Costs Calculator alongside listings
- Claimed to have the most rental listings of any UK portal as of late 2021
Where Zoopla falls short:
- Lower overall traffic than Rightmove — roughly half as many monthly visitors
- Alert delays similar to Rightmove's batched email system — we explored this in our Zoopla notifications guide
- Coverage can be thinner in smaller towns and rural areas
- Most agents dual-list on both Rightmove and Zoopla, so the overlap is high — but the listings that only appear on Zoopla are the ones you miss by not checking it
Zoopla is not a smaller copy of Rightmove. A meaningful number of agents list on Zoopla but not Rightmove, or list there first. For a thorough rental search, checking both is the minimum.
OnTheMarket
OnTheMarket launched in 2015 as an agent-owned challenger to the Rightmove and Zoopla duopoly. In December 2023, it was acquired by CoStar Group — a major US property data company — which has since invested heavily in growing the platform's listings and traffic.
What OnTheMarket does well:
- "Only With Us" early access: participating agents list properties on OnTheMarket 24 hours or more before they appear on Rightmove or Zoopla. This is their primary differentiator and it is a genuine advantage for renters who want first sight of new listings
- Growing rapidly: traffic increased over 200% following the CoStar acquisition, and listing volumes are up nearly 50%
- A landmark deal with the Connells Group in early 2026 brought listings from over 1,200 branches — including Hamptons, William H Brown, and Bairstow Eves
- Less cluttered interface than Rightmove
Where OnTheMarket falls short:
- Smallest of the three major portals by total listing volume — estimated at 500,000 to 700,000 listings compared to Rightmove's 1.1 million+
- Lower public awareness means fewer renters check it, which is actually an advantage for those who do (less competition per listing)
- Search functionality is less refined than the bigger two
The fact that fewer renters use OnTheMarket works in your favour. Less competition on each listing means your enquiry is more likely to get a response. We compared OnTheMarket and Rightmove in detail in our OnTheMarket vs Rightmove guide.
OpenRent
OpenRent is the UK's largest online letting platform by volume, and it operates on a completely different model to the other portals. Instead of agents listing properties, landlords advertise directly to tenants — cutting out the middleman entirely.
What OpenRent does well:
- No tenant fees whatsoever — OpenRent charges landlords a listing fee, not tenants
- Over 8 million registered tenants and landlords, with more than 1.4 million lettings facilitated since 2012
- Direct landlord contact means faster communication and often more flexibility on move-in dates and terms
- Often cheaper rents — landlords who save on agent commissions (typically 8-15% of annual rent) frequently pass some of that saving on to tenants
- Full digital process: viewing booking, referencing, deposit registration, and contract signing all handled online
Where OpenRent falls short:
- Rentals only — no sales listings
- Quality and professionalism varies since landlords self-manage without agent vetting
- Less neighbourhood data and search tooling compared to Rightmove or Zoopla
The exclusive listings you're missing: OpenRent offers landlords a free advertising tier that only appears on OpenRent itself — not on Rightmove, Zoopla, or any other portal. This means there is a significant pool of rental listings that you will never see unless you check OpenRent directly. The paid tier (£49) syndicates to Rightmove and OnTheMarket, but free-tier listings remain OpenRent exclusives.
SpareRoom
SpareRoom is not a direct alternative to Rightmove — it serves a completely different market. If you are looking for a room in a shared house or flat, or searching for a flatmate, SpareRoom is the only major dedicated platform in the UK.
What SpareRoom does well:
- The UK's number-one flatshare site with tens of thousands of rooms available at any given time
- Flatmate compatibility matching based on lifestyle preferences, habits, and personality
- "Buddy Up" feature lets you team up with someone else to find a place together
- Specialist categories: student housing, LGBT-friendly flatshares, weekday-only lets, live-in landlord rooms
- Average UK room rent of £753 per month (Q3 2025) — significantly cheaper than renting a whole property
Where SpareRoom falls short:
- Rooms and flatshares only — you cannot find whole flats or houses
- Premium features (early access to new ads, visibility boosts) require a paid membership
- Thinner inventory outside major cities
SpareRoom's listings appear on no other property portal. If you are open to shared living — whether to save money, for social reasons, or because you are new to a city — ignoring SpareRoom means ignoring an entire segment of the rental market.
PrimeLocation
PrimeLocation is owned by the same parent company as Zoopla and draws from a similar agent network. It positions itself as a premium property portal, with particular strength in higher-end and international listings.
What PrimeLocation does well:
- Over 1 million properties listed across sales and rentals
- Listings from over 16,000 agent branches, with prominent coverage from premium agents like Knight Frank and Hamptons
- International property listings across 60+ countries
Where PrimeLocation falls short:
- Very high overlap with Zoopla's listings — the same parent company, the same agent backend
- Smaller traffic and lower brand recognition than the other portals
- Premium positioning means less coverage of affordable rental stock
- No private landlord listings — agents only
PrimeLocation is most useful for renters looking at the higher end of the market or searching internationally. For the average UK renter, checking Zoopla covers most of the same ground.
The Problem With Checking Multiple Sites
Knowing you should search multiple portals is one thing. Actually doing it is another.
Running separate searches on Rightmove, Zoopla, OnTheMarket, OpenRent, and SpareRoom — each with their own saved criteria, alert settings, and notification schedules — becomes a chore within days. You see the same listings duplicated across portals. You miss new ones because alert timings don't match. You start forgetting to check the portals you visit less often.
This is especially painful if you are searching in more than one area. Multiply five portals by two cities and you are managing ten separate searches. The cognitive overhead causes alert fatigue, and alert fatigue causes missed properties.
How to Monitor All UK Rental Portals at Once
This is the problem Dwellio was built to solve. Rather than checking Rightmove, Zoopla, OnTheMarket, OpenRent, SpareRoom, and PrimeLocation separately, Dwellio monitors all six portals continuously and sends you a single alert when a matching property appears on any of them.
You set your criteria once — location, budget, bedrooms, property type — and Dwellio handles the rest. Alerts arrive within minutes of a listing going live, not hours later in a batched email digest. Dwellio also deduplicates across portals, so you won't receive the same property twice even if it's listed on Rightmove and Zoopla simultaneously.
For renters in competitive markets, this removes the two biggest disadvantages: the time gap between a listing appearing and your finding out about it, and the coverage gap from only checking one or two portals.
Dwellio offers a 14-day free trial with no card required — £9.99 per month after that. If you've been limiting your search to a single site, it might be time to see what you've been missing.
Frequently Asked Questions
What is the best alternative to Rightmove for renters?
For whole-property rentals, Zoopla is the strongest single alternative — it has the second-largest inventory and strong letting agent partnerships. But for genuine coverage, you need multiple portals: Zoopla for agent-listed properties, OpenRent for landlord-direct listings, and OnTheMarket for early-access "Only With Us" listings that appear before they hit Rightmove.
Is Zoopla better than Rightmove for renters?
Rightmove has more total listings and higher traffic in most areas. Zoopla's strengths are its Travel Time Search feature and competitive agent coverage, particularly in London and other major cities. Neither is strictly better — they have different agent networks, and checking only one means missing listings on the other.
Are there rental properties not listed on Rightmove?
Yes. OpenRent landlords using the free advertising tier only appear on OpenRent — not Rightmove. Some agents list exclusively on OnTheMarket or Zoopla due to commercial arrangements or cost. SpareRoom's flatshare listings appear on no other portal. According to industry estimates, Rightmove covers 80-90% of agent-listed properties, but that still leaves a meaningful gap.
What sites do landlords use other than Rightmove?
Landlords who manage properties themselves commonly use OpenRent, which offers direct-to-tenant advertising without agent fees. Agents typically list on a combination of Rightmove, Zoopla, and OnTheMarket. Some landlords also advertise on Gumtree, Facebook Marketplace, and local community groups — though these carry higher scam risk and less tenant protection.
How do I get alerts from multiple property sites at once?
You can set up separate saved searches on each portal individually, but this creates duplicate notifications and alert fatigue. Services like Dwellio monitor all major UK portals simultaneously and send you a single deduplicated alert within minutes of a match appearing on any of them. This is the most practical way to cover the full market without checking multiple sites manually.
