DOI GROUP LTD

What DOI GROUP LTD does

DOI Group Limited is a privately held UK commercial refurbishment specialist founded in April 1990 (originally as Designed Office Interiors) and headquartered in Waltham Cross, Hertfordshire. The firm offers an integrated, project-based service covering space planning and Computer Aided Design (CAD) with 3D visualisation, end-to-end contractual refurbishment (partitioning, ceilings, electrical, data/telephony, lighting, air conditioning, access control, AV), office furniture and storage supply (including bespoke joinery manufactured via a Wales partner alongside sourced UK and European brands), logistical move management, and planned preventative maintenance. Its revenue model is project-based, bespoke-quoted, with payment schedules agreed before commencement; materials remain DOI property until paid in full, and pricing is not publicly disclosed.

The company serves large enterprise and public-sector clients alongside small entrepreneurs under a one-to-one project management policy. Named customers include the Financial Times, Barclays Bank, Citi Group, Pearson, Ernst & Young, Charles Stanley, Marks & Spencer, KFC, Pizza Hut, Riverstone Europe, NHS PCTs, and multiple schools and GP surgeries. Operating geography is restricted to the United Kingdom — primarily East Anglia, Central and South East England, and London — with go-to-market executed through direct, consultative sales from the Hertfordshire headquarters, repeat business, and client referrals. Marketing relies on a portfolio of blue-chip logos and four sector accreditations (Safe Contractor, Environment Agency, Incensu, Altius) rather than paid acquisition channels.

Operationally, the business is small — the firm reports 6 employees — and is likely founder-owned, with no disclosed institutional investment, parent company, M&A activity, funding rounds, or public financial reporting. Inputs describe many team members as having been with the company since its founding, and clients reportedly request specific DOI individuals by name for repeat engagements, indicating that the business's competitive position rests more on relationship continuity and brand tenure than on scale, technology differentiation, or AI capability, of which there is no evidence.
