Hometrack and Landmark both occupy senior positions in the UK property data market, but they serve fundamentally different parts of the property lifecycle. Understanding which does what - and where the gaps sit - matters if your team is evaluating suppliers for lending, insurance, conveyancing, or property services.
This comparison sets out what each platform offers, where each has clear advantages, and where procurement teams should look elsewhere for capabilities that neither provides.
Who is Hometrack?
Hometrack was founded in 1999 and sits within the Houseful group alongside Zoopla, Alto, and Primelocation. Silver Lake Partners acquired the parent group for approximately £2.2 billion in 2018. Hometrack was brought into the fold a year earlier for £120 million.
The company is best known for its Automated Valuation Model, which is used by 18 of the top 20 UK mortgage lenders and processes over 50 million valuations per year. It was the first UK AVM to receive accreditation from Moody's, S&P, and Fitch - a credential that remains relevant for institutions issuing residential mortgage-backed securities. Beyond the AVM, Hometrack operates the Property Risk Hub, a cloud-native decisioning platform that integrates valuation, risk data, business rules, case management, and surveyor allocation into a single lending workflow.
In recent years, Hometrack has added climate change insights covering flood, subsidence, coastal erosion, and energy efficiency, as well as a broader Data Services division drawing on Zoopla's market intelligence.
Who is Landmark?
Landmark Information Group was incorporated in 1994 and is wholly owned by DMGT (Daily Mail and General Trust), the private media group controlled by Lord Rothermere. DMGT's Property Information division - which includes Landmark alongside Trepp and Yopa - generated £219 million in revenue in FY2024.
Landmark's core business is property and environmental risk data for the conveyancing market. The group operates through more than a dozen subsidiary brands: SearchFlow for conveyancing searches, OneSearch Direct for local search data, Millar & Bryce for Scottish property searches, Ochresoft for conveyancing workflow software, and Optimus for panel management - among others.
The company holds exclusive data partnerships, including sole commercial partner status with the Environment Agency for surface water flood data with depth measurements. It draws on over 700 datasets from nearly 400 data suppliers and claims involvement in over 97% of property transactions in England and Wales. Landmark also runs SPN+, a valuation instruction network that processes 1.5 million mortgage valuation instructions per year for every major high-street lender.
Feature comparison
Automated valuation capability
This is a straightforward distinction. Hometrack offers one of the UK's most established AVMs - rating-agency accredited, embedded in the majority of UK mortgage origination workflows, and processing more than 50 million valuations annually. Its newer Digital Valuer product combines the AVM with machine learning models to reduce the need for physical valuations.
Landmark does not offer an AVM. Its valuation services arm (SPN+) manages the instruction process between lenders and surveyors but does not produce automated property valuations. If your use case requires AVM output, Hometrack is the only choice between these two.
Environmental and property risk data
Here, the dynamic reverses. Landmark's environmental data is deep, consultant-backed, and legally relied upon in conveyancing. Products like Envirosearch Residential and RiskView cover contaminated land, flood risk (including surface water with Environment Agency depth data), ground stability, radon, coal mining, climate change projections, and chancel repair liability. Every report carries £10 million professional indemnity cover and can include a manual review from Landmark's in-house consultancy, Argyll Environmental.
Hometrack's climate change insights module covers flood, subsidence, coastal erosion, and energy efficiency. It integrates with the Property Risk Hub for mortgage origination decisioning and supports Bank of England climate stress tests. However, Hometrack's environmental data is narrower in scope - designed for lending risk assessment rather than the full spectrum of conveyancing due diligence that Landmark addresses.
Conveyancing integration
Landmark dominates this space. Its report suite is the industry standard for residential and commercial property searches in England, Wales, and Scotland. SearchFlow provides a single point of access for conveyancing searches, and Ochresoft's workflow software is used by law firms to manage the conveyancing process end to end. Landmark's LandmarkConnect platform aims to create a cross-industry digital ecosystem linking estate agents, conveyancers, and valuers.
Hometrack has no direct conveyancing product. It touches the conveyancing-adjacent lending workflow through the Property Risk Hub but does not compete in environmental searches, local authority searches, or legal due diligence reporting.
Market intelligence
Hometrack has a clear edge through its relationship with Zoopla. Access to real-time listing data, search behaviour, supply and demand metrics, and pricing trends gives Hometrack a forward-looking market intelligence capability that no conveyancing-focused provider can match. The Zoopla House Price Index is widely referenced in industry and media.
Landmark publishes quarterly property trend reports and industry research - its Estate Agency Market Research Report and Project 28 Charter are notable contributions - but does not have an equivalent live market data product.
Pricing and access model
Neither company publishes transparent pricing for its core products. Hometrack operates on enterprise contracts negotiated per lender, with pricing that varies by volume and product bundle. Landmark's residential conveyancing reports are priced per report - starting at £59.75 plus VAT for the basic Homecheck screen and rising to £131.25 plus VAT for the comprehensive RiskView package. Individual flood, planning, or energy searches cost £42.50 plus VAT each.
Both models are designed for professional users within established workflows. Neither offers self-serve API access, pay-as-you-go per-property data, or developer-friendly onboarding.
Where Hometrack is stronger
Hometrack is the obvious choice for mortgage lending workflows. Its AVM accreditations (Moody's, S&P, Fitch) are non-negotiable for institutions involved in securitisation, and the Property Risk Hub provides an integrated decisioning layer that Landmark cannot match. If your use case is mortgage origination, risk modelling, or portfolio revaluation, Hometrack is purpose-built for it.
The Zoopla data partnership gives Hometrack an additional advantage in market intelligence - real-time supply, demand, and pricing data that informs both lending decisions and strategic planning.
Where Landmark is stronger
Landmark owns the conveyancing risk data space. Its environmental reports are the standard that solicitors and conveyancers rely on for regulatory compliance, and its exclusive data partnerships - particularly with the Environment Agency - provide risk intelligence that Hometrack does not replicate. The £10 million PI cover on reports is a practical differentiator for legal professionals who need professional indemnity assurance.
The breadth of the Landmark group - spanning conveyancing searches, panel management, mapping, workflow software, and estate agency compliance - means it touches more parts of the property transaction than Hometrack, which remains focused on the lending layer.
For organisations working across the transaction lifecycle rather than just the mortgage decision, Landmark offers a more complete ecosystem.
Where Chimnie fits in
Both Hometrack and Landmark are enterprise platforms with opaque pricing, extended sales cycles, and products designed for specific professional workflows. Neither offers transparent per-property data access, and neither covers the full spectrum of property attributes that modern proptech, insurance, and data teams increasingly need.
Chimnie occupies the space between them. Its API delivers over 500 attributes per UK property - covering the structural and environmental risk data that Landmark addresses, the valuations that Hometrack provides, and additional datasets that neither offers. These include planning permissions (completing two years of national ingestion, launching imminently), outbuilding detection and classification mapped separately from the main dwelling, and rebuild cost estimates with confidence intervals. Commercial property data is available at £0.45 per property on a pay-as-you-go basis with ratecard volume discounts.
Chimnie's pricing starts at £0.05-0.15 per residential property - a fraction of Landmark's per-report costs and dramatically more accessible than Hometrack's enterprise contracts. The free AVM provides valuations with calibrated confidence intervals, and API-first delivery with self-serve onboarding means teams can start evaluating data in hours rather than weeks. Over 150,000 consumer users validate the underlying data on Chimnie's research platform, providing a continuous feedback loop that purely B2B providers lack.
For organisations that need property-level intelligence outside the specific lending or conveyancing workflows that Hometrack and Landmark serve - insurance underwriting, portfolio management, proptech development, estate agency compliance - Chimnie is worth evaluating through a free trial before committing to either enterprise platform.
Conclusion
Hometrack and Landmark serve different markets and barely compete with each other directly. Hometrack is the mortgage AVM and lending decisioning platform. Landmark is the conveyancing risk and environmental reporting standard. Both are deeply embedded in their respective workflows and will remain there.
The gap sits in property-level data access for everyone else - the insurers, brokers, proptech firms, developers, and analysts who need rich property attributes without enterprise procurement cycles. That gap is where API-first providers are gaining traction, and where procurement teams should be testing alternatives alongside their existing supplier relationships.
