Hometrack
Hometrack is a London-based property data, valuation and analytics company whose house price indices and market reports have been cited by British national media for more than two decades. Founded in 1999, it built its name on automated valuation models — computer estimates of what individual homes are worth — supplied to mortgage lenders, and on a monthly reading of the housing market that became one of the most closely watched indicators of UK house prices. Acquired by Zoopla Property Group (ZPG) in February 2017 for £120 million, it continued as a standalone brand within the group, which is now known as Houseful, the Silver Lake-owned business that also owns Zoopla, PrimeLocation, Alto and Jupix. Today Hometrack describes itself as a property data, valuation and risk-decisioning company, serving lenders, surveyors, brokers, housing associations and investors rather than homebuyers directly.
Founding and the automated valuation idea
Hometrack was established in 1999, at the start of the online property era, to apply data and statistical modelling to a market that had traditionally relied on individual surveyors' judgement. Its central product was the automated valuation model, or AVM: a system that estimates a property's value from Land Registry price data, property characteristics and comparable sales, in seconds rather than days. The company launched its AVM in 2002 and says it was the first AVM provider accredited by the ratings agencies Moody's, Standard & Poor's and Fitch — accreditation that mattered because lenders' mortgage books, valued using Hometrack technology, were scrutinised by those agencies. It is a founding member of the European AVM Alliance, the industry body for automated valuation providers. By the mid-2010s the firm was generating more than 20 million automated valuations a year in the UK and Australia; it now says it runs more than 50 million valuations annually.
The house price index and the media
For most news consumers, Hometrack meant its index. The company's monthly survey-based reporting on house prices in Britain's major cities was a staple of property journalism: a regular, early reading on whether prices were rising or falling, city by city, quoted by newspapers, broadcasters and news agencies in the same breath as the Nationwide, Halifax and Land Registry measures. Because the index was built from the firm's own market intelligence, it often moved the news agenda at the start of the month, setting the tone for coverage of affordability, first-time buyers and the health of the housing market. Its chief economist's commentary accompanied the figures for many years, giving the data a named, accountable interpreter — a model of how a data company becomes a news source.
Who uses Hometrack
The paying customers are institutions, not the public. At the time of its acquisition, Hometrack provided residential property market insights, analytics, valuations and data services to more than 400 partners, including mortgage lenders, new home developers, investors, housing associations and local authorities. It partnered with 15 of the top 20 UK mortgage lenders — a figure it now puts at 18 of the top 20 using its AVM in their origination processes — and with all four leading Australian mortgage lenders, from offices in London and Sydney, with 55 staff at the time of the deal. Its position in the market is on the lending and risk side of the value chain: valuation, comparable evidence, climate and property risk data, surveyor allocation and case management, delivered increasingly through software interfaces to lenders' systems.
The ZPG acquisition
On 1 February 2017, Zoopla Property Group announced it would acquire Hometrack for £120 million. Hometrack had generated revenues of £15.5 million and adjusted EBITDA of £7.1 million in the year to 30 June 2016. ZPG's founder and chief executive, Alex Chesterman, called Hometrack the clear market leader in automated valuation services in the UK and said the deal gave the group unrivalled capabilities to serve its estate agent and developer partners. Hometrack continued to operate as a standalone brand and platform, and its team became the cornerstone of ZPG's data services business, headed by Hometrack's chief executive, Charlie Bryant, who said the two companies shared a vision of using data to help partners operate more effectively. The acquisition signalled how valuable housing data had become: a portal group was willing to pay £120 million for the company that priced the nation's homes.
From ZPG to Houseful, and the Zoopla rebrand of the index
Ownership changes reshaped the public face of the business. After ZPG was taken over by the US private equity firm Silver Lake, branding across the group was simplified around Zoopla. In January 2019, the monthly cities index that had been published under the Hometrack name for many years was rebranded as a Zoopla index, though it continued to be produced from Hometrack's data and methods; the edition announcing the change reported, for example, Edinburgh as the fastest-growing major city of 2018, with prices up 6.8 per cent, followed by Liverpool at 6.3 per cent. The parent group later took the name Houseful, under which Hometrack now sits alongside the Zoopla portal and the group's estate agency software businesses. The Hometrack brand itself survived where it mattered — in the professional market, where lenders buy valuation and risk services under its name.
Products today
Hometrack's current offer extends well beyond the original AVM. Its developer portal lists a suite of data services for commercial clients, including a valuation API, a broker-facing AVM service, and property risk and climate data products — reflecting the growing importance of flood risk, subsidence and other climate-related factors in mortgage lending decisions. Access is commercial, through API keys issued to contracted clients. In the UK value chain, the company deliberately does not compete with the listings portals; it supplies the infrastructure behind lending decisions — the valuations against which mortgages are approved, the risk flags that trigger a physical inspection, and the portfolio analytics that let lenders and investors understand what they hold.
Why its data matters to the news
Hometrack's significance for the media rests on two assets: a longitudinal dataset on British house prices and values, and a position inside the mortgage machine that few commentators can match. When its indices report prices stalling in London or surging in northern cities, journalists are not merely quoting an opinion — they are citing the firm whose models help set the value of the housing stock those prices describe. Its market reports, now largely published under the Zoopla banner, remain a standard reference in coverage of the housing market, cited alongside official statistics. For this directory, Hometrack belongs in the agencies and data services category as a supplier of property intelligence that news organisations depend on to report the market accurately.
Competition and context
Hometrack operates in a landscape of rival measures and models. Nationwide and Halifax publish indices from their own mortgage approvals; the Office for National Statistics produces the official UK House Price Index from Land Registry records, more comprehensive but slower; Rightmove and Zoopla publish asking-price data. Automated valuation, meanwhile, has become a contested technology in itself, with lenders balancing its speed and cost against the risk of error on unusual properties — the reason human surveyors remain part of the system Hometrack sells into. The firm's longevity, ratings-agency accreditation and lender penetration have kept it at the centre of that system through the financial crisis, the pandemic housing boom and the rate rises that followed.
