Mumford & Wood

What Mumford & Wood does

Mumford & Wood is a UK manufacturer of bespoke timber windows and doors, founded in 1954 and headquartered in Tiptree, Essex. The company designs, manufactures, and installs made-to-measure timber fenestration products across three core window types (Box Sash, Spring Sash, Casement and Flush Casement) and seven door types (French, Single, Balcony, Stable, Bifold, Patio, and Entrance), plus Roof Lanterns, organised under three ranges: Conservation, Classic, and Heritage. Manufacturing is anchored on engineered Redwood and Red Grandis timber with multi-point locking systems, advanced glazing options including Krypton gas-filled units, and FSC/PEFC-certified sustainable sourcing. The company holds ISO 9001 and ISO 14001 certifications and operates as part of the Performance Timber Products Group.

The business serves five primary customer segments: architects, developers, builders and contractors, interior designers, and self-builders/end clients, with a particular specialisation in listed buildings, conservation areas, and heritage projects including Elizabeth Castle in Jersey and the KOKO Theatre in London. The go-to-market combines enterprise field sales, quote-based bespoke project work (Request an Estimate with a 24-hour response commitment), three physical showrooms (London, Swindon, Guernsey), factory tours, and RIBA/BIID accredited CPD training sessions for architects and interior designers. Pricing is not publicly disclosed; all orders are quoted against project specifications.

Revenue is generated primarily through one-time bespoke product sales for residential and commercial projects, supplemented by CPD training services. Distribution is principally direct to enterprise and end clients, with supplementary reach through builder merchants and NBS Source specification listings. The company has not raised external funding, is privately held, and operates as a separate legal entity within the Performance Timber Products Group alongside shared IT, logistics, compliance, finance, and customer service functions.

Direct peers

• Rationel: Danish-owned manufacturer of timber and timber/aluminum composite windows and doors with a UK sales operation. Comparable in premium performance positioning, sustainability messaging, and architectural specification channels.
• English Heritage Windows: UK specialist in heritage and conservation timber windows and doors. Closely comparable on heritage niche, listed-building expertise, and slim-profile putty-glazed product details.
