Connells Group

Connells Limited, trading as Connells Group, is the United Kingdom's largest estate agency and property services group, headquartered at Cumbria House in Leighton Buzzard, Bedfordshire, and a wholly owned subsidiary of Skipton Building Society. It states 1,200+ branches, 16,000+ colleagues, more than 80 local brands including Connells, Countrywide, Hamptons, Sequence, Bairstow Eves, Fox & Sons, John D Wood & Co, Gascoigne Halman and Blundells, roughly 115,000 property sales a year and about 10% market share, 165,000+ managed tenancies and £33bn+ of arranged mortgage lending. It occupies almost the entire residential value chain at once: estate agency, residential and corporate lettings, new homes, land and planning, auctions, surveys and valuations, conveyancing, mortgage services, asset management, affordable housing, EPCs and inventories, commercial agency and a research and consultancy practice. Its home market is the United Kingdom, where there is no MLS and no cooperative listing standard — residential stock reaches consumers through the Rightmove and Zoopla portal duopoly by way of agency CRM and website software rather than a shared pool, and Connells' own consumer property sites are built on the Homeflow platform. Its API posture is closed and undocumented. No developer portal exists: developer., developers., api. and docs.connellsgroup.co.uk do not resolve, and /developers, /api, /docs, /openapi.json, /swagger.json, /api-docs and /.well-known/openid-configuration return 404 on both connellsgroup.co.uk and connells.co.uk. It publishes no OpenAPI, no GraphQL, no AsyncAPI, no MCP server and no client SDK — the only first-party package on any public registry is a dormant npm colour-token file for its website. Probing on 2026-07-26 did, however, find a small live JSON surface underneath the consumer site at https://www.connells.co.uk/api: six anonymous read-only Next.js route handlers serving the branch finder, people directory, testimonials wall and place autocomplete, plus a seventh (/api/properties) that returns HTTP 500. These are undocumented internal website routes, not a product — unversioned, unsupported, rate limited by Cloudflare, capped at 12 records because no paging parameter works, and carrying application errors inside HTTP 200 bodies. Only connells.co.uk exposes them; the sibling brand sites redirect /api/* away. The group's 88-URL corporate sitemap contains no developer path — its one /developers/ page is addressed to property developers, not software developers. Integration is real but partner-only: Connells Survey & Valuation advertises delivering "totally integrated panel and risk management technology solutions to lenders" for the 40+ lenders whose valuation panels it manages, and reaches them through third-party platforms such as Cotality's LenderHub, while Countrywide Surveying Services' Geoconnect engine is described as connecting internal and external data sources through API integrations it consumes rather than publishes. There is no RESO Web API or Data Dictionary certification, no OData $metadata document and no Universal Property Identifier anywhere in the estate — RESO is a North American NAR/MLS mechanism and the UK has no MLS to certify against. Connells publishes no open data either; its research product, covering 88% of UK postcode areas from branch-level proprietary data, is sold through a brochure request and a contact form, and the genuinely open UK property layer belongs to the public sector (HM Land Registry Price Paid Data and Ordnance Survey), not to the brokerage.

Connells Group publishes 1 API on the APIs.io network: Connells Website JSON API (undocumented). Tagged areas include Real Estate, United Kingdom, Property Listings, Brokerage, and Estate Agency.

Connells Group’s developer surface includes code examples, authentication, engineering blog, and 29 more developer resources.

  description: 'An undocumented, unauthenticated, read-only JSON surface served by the Connells consumer website at https://www.connells.co.uk/api.
    It is NOT a published Connells Group product — the group publishes no developer portal, no documentation and no specification,
    and makes no commitment about these routes. They are Next.js App Router route handlers backing the site''s branch finder,
    people directory, testimonials wall and place autocomplete, with content sourced from the Homeflow estate-agency platform
    that powers the Connells consumer estate. Six operations answered anonymous requests on 2026-07-26 — listBranches, getBranch,
    listStaff, listTestimonials, listLocations and searchPlaces — while a seventh, /api/properties, returned HTTP 500 on every
    probe, so no property listings are available. The surface is unversioned, read-only (Allow: GET, HEAD, OPTIONS), rate
    limited by Cloudflare with HTTP 429 and Retry-After but no forward RateLimit headers, and hard-capped at 12 records per
    collection because no paging parameter is honoured despite pagination metadata advertising 162 branches and 841 staff.
    Application errors ride inside HTTP 200 bodies rather than in status codes. Only www.connells.co.uk exposes these handlers;
    the sibling Connells Group brand sites redirect /api/* away. The OpenAPI in this repo was derived by API Evangelist from
    live response captures, not published by the provider.'
