What J W Rihoy & Son does

J W Rihoy & Son Limited is a privately held, Guernsey-domiciled building contractor founded in 1924, employing more than 250 staff and operating as the island's longest-established and largest contractor. The company delivers construction projects across all tiers and segments — residential (sympathetic renovations, modern private homes, social housing), commercial (hospitality, retail, commercial fit-outs), and light industrial (e.g., Spur Point) — through both traditional and design-and-build contracts.

The service model is organized around three core construction divisions plus two specialized units: a Bespoke Projects Division handling smaller projects including insurance damage rectification, domestic extensions and alterations, and commercial re-fits; and an in-house Joinery Workshop manufacturing and installing interior and exterior joinery (stairs, doors, windows, gates) for both residential and commercial clients. The company holds the Channel Islands' first CIOB Chartered Building Company status, attained in 2001, and operates primarily via direct enterprise field sales against quote-based construction contracts.

The business generates revenue through one-time, project-based construction contracts (with insurance rectification work as a recurring smaller-ticket stream) distributed across residential, commercial, and industrial end markets within Guernsey alone. Pricing is not publicly disclosed; contracts are quote-based. Distribution is direct sales with no intermediaries, supported by an organic social media presence (LinkedIn, Facebook, Instagram) and a company newsletter rather than paid acquisition channels. Ownership remains private with no disclosed parent, subsidiary, or external investor structure, and the company is complemented by The EJ Rihoy Charitable Trust handling overseas community initiatives.
