What Solidor does
Solidor is a UK-based manufacturer of premium composite doors, founded in 2000 and operating for over 20 years from a manufacturing site in Staffordshire. The company designs and produces composite doors built around a solid timber core with Through' Colour ABS skins — a construction method it positions as differentiated from foam- or hollow-core competitors — delivering doors that meet UK building regulation U-Values of 1.4 or below and integrating police-approved, insurance-validated multipoint locking systems (Ultion Plus 3, Avocet ABS 3, Winkhaus, Avantis) plus optional Nuki Smart Lock connectivity for keyless entry and voice-assistant control. Its product portfolio spans front doors, back doors, stable doors, French double doors, arched doors, narrow doors, and side panels, organised across two style ranges (Traditional and Contemporary Italia) with the broadest colour offering in the UK market at 32+ colours across five collections and the ability to specify different colours inside and out.
The company operates a B2B2C go-to-market model: it manufactures doors and distributes them through a nationwide network of approved installers who handle quoting, surveying, and installation for end consumers. A cloud-based trade portal (cloud.solidor.co.uk) supports installer partners with ordering and technical resources, while the consumer-facing website features an online Door Designer tool for configuration and direct quote requests that are routed back to local installers. Revenue is generated almost entirely from one-time hardware sales — composite doors priced at £1,000-£3,000 per unit, with average fully-fitted installations of £1,500-£2,500 — supplemented by accessories and hardware add-ons. All manufacturing and revenue generation is concentrated in the United Kingdom, with no disclosed international operations. Solidor is a private subsidiary of Premdor Crosby Ltd, a diversified group that received investment from NorthEdge Capital in 2014.

Solidor competitors and assessment
Company assessmentDirect peers
- Endurance Doors: UK-based manufacturer of solid timber core composite doors targeting the same residential replacement and new-build channels. Closest like-for-like competitor given comparable product construction, colour range, and installer-led distribution.
- Comp Door: UK composite door manufacturer with a similar niche positioning around solid-core construction and installer-led distribution; competes directly for the same trade and homeowner replacement demand.
- Rockdoor: UK manufacturer of premium composite doors with strong security credentials, directly competing with Solidor on installer channels and front-door ASP positioning; comparable on security certifications and product breadth.
- TruFrame: UK trade-supplier fabricator of doors, windows, and composite doors serving installer networks; comparable trade-channel business model and product overlap in composite door supply.
- Door-Stop International: Direct UK composite door competitor selling through approved installer networks with comparable solid timber core products and similar price points, making it a head-to-head comparable in the dealer-channel.
- Apeer: UK-based composite door maker with overlapping installer-led distribution and similar solid-core product positioning; comparable target customer (UK residential replacement) and price band.
Broad incumbents
- Jeld-Wen: Global building products incumbent with a UK door and window portfolio; competes at the broader residential door category level with wider distribution and greater scale than Solidor's niche offering.
- Premdor: Sister brand under Premdor Crosby Ltd, Solidor's parent group; produces internal and external doors with broader timber door portfolio, making it a closely related group comparable and intra-group substitute.
- Hörmann: European door and operator manufacturer with a UK residential door offering; broad incumbent with deeper R&D and international footprint, providing a wider category benchmark for Solidor's premium positioning.
Others
- MASCO Corporation: Diversified building products group with coatings and door-adjacent brands; not a direct competitor but provides a public-market reference for building-products business model valuation and operating benchmarks.
