Chimni

What Chimni does

Chimni Ltd. is a UK-based property technology company headquartered in West London, with a secondary base in Dublin established early in operations. Founded by Nigel Walley, the company operates a cloud-based digital property logbook that aggregates home-related documents, certificates, warranties, online accounts, and project records into a single dashboard for homeowners. The platform integrates with UK government services including HM Land Registry and the EPC Register, and extends into specialized modules for property professionals: estate agents (with Property Information Form generation and integration into agency software such as Reapit), conveyancers, and housebuilders via the ChimniPro digital handover pack service, plus a Retrofit Planning Module aligned to Green Finance Institute data standards.

The revenue model combines a freemium consumer tier (free logbooks for individual homeowners) with subscription-based business services and professional fees. Estate agents, conveyancers, and housebuilders subscribe for premium features and integration capabilities, while additional revenue comes from concierge document scanning and search services. Go-to-market is hybrid: product-led self-serve sign-up for consumers, and direct sales plus channel partnerships for B2B segments. Chimni has positioned itself around adjacent regulatory and sustainability themes, including InnovateUK-funded work on linking BIM construction data to homeowner logbooks via a partnership with OpenBIM specialist xbim, and founder membership in the Renovation Loan Blockchain Association.

Chimni remains a small founder-led company with 1-10 employees and no disclosed institutional venture funding beyond the InnovateUK grant. Customer references are predominantly small-to-mid-market: individual homeowners, buy-to-let investors with handfuls of properties, boutique estate agencies (e.g., Horton&Garton), and individual housebuilders, with no large enterprise logos disclosed. The company competes within UK proptech by emphasizing homeowner data ownership and integration with authoritative government sources rather than on proprietary AI/ML capabilities, none of which are described in available materials.

Core offering

Chimni operates a cloud-based digital property logbook platform that aggregates homeowners' documents, certificates, warranties, utility and insurance accounts, and project records in one secure environment. The platform serves individual UK homeowners via a free tier and property professionals (estate agents, conveyancers, housebuilders, retrofit professionals) via subscription modules that reduce transaction fall-throughs and streamline conveyancing, sales onboarding, and digital handover processes.

Product overview

Chimni offers a unified platform anchored by the Chimni Logbook—a digital property logbook akin to a car's service record. The core platform serves individual homeowners, while specialized modules target business users: Chimni for Estate Agents, Chimni for Conveyancers, and ChimniPro for Housebuilders. The Retrofit Planning Module extends the platform forward in time to help homeowners plan NetZero retrofit work. All products share the same underlying logbook infrastructure, allowing data to pass with property ownership.

Scale indicators5 records

Recent moves5 records

Expansion highlights5 records

Broad incumbents

• Reapit: UK-leading estate agent CRM and property platform; Chimni already integrates with Reapit for Property Information Form upload. Competes for the same B2B wallet share among estate agents and could expand into property-logbook functionality as a feature.
• Dye & Durham: Canadian-listed property technology platform serving UK conveyancers, lawyers, and property professionals with searches, due diligence, and workflow tools. A well-capitalised incumbent competing for the same conveyancer and transaction-process budget that Chimni targets.
• tmgroup: UK conveyancing services and technology provider offering property searches, due diligence, and workflow tools. Comparable to Chimni's conveyancer-facing module in target customer and workflow overlap.
• Coyote Software: UK conveyancing case management software provider serving law firms. Overlaps with Chimni for Conveyancers in workflow integration and document delivery into legal practices.
• Houzz Pro: Home renovation and design platform with professional tools for project management, client communication, and documentation. Comparable in serving the project-management and contractor side of home improvement, an adjacent use case to Chimni's project planning templates.

Direct peers

• HomeZada: US-based home management platform offering a digital property logbook covering documents, maintenance, inventory, and project records for homeowners. Closest direct competitor by product concept, serving the same 'single source of truth for home data' use case.
• Centriq: Mobile-first home management app aggregating manuals, warranties, appliances, and service records for homeowners. Directly comparable as a consumer-facing property logbook with similar document-and-asset-centric scope.

Emerging players

• Bold Property: UK property transaction platform offering digital tools for agents, buyers, and sellers. Comparable in targeting the property-transaction workflow and competing for agent and consumer adoption in the same geography.
• Sortly: Inventory and asset management app with home and SMB use cases. Overlaps with Chimni's inventory and document-management features, particularly the Chimni Inventory Manager module that connects to insurance providers.

Others

• InfoTrack: UK property search and conveyancing technology provider supplying data feeds and ordering platforms into legal practices. Comparable as a property-data infrastructure layer and potential integration partner or competitor in the conveyancer workflow.
