What Zenith Windows does
Zenith Windows Limited is a privately held, family-run home improvement company registered in England (company number 13266658), headquartered in Romford, Essex. The company manufactures, supplies, and installs a broad portfolio of exterior building products for residential homeowners, with the core offering centred on A-rated energy-efficient uPVC double-glazed windows and doors manufactured in-house at its Romford factory. Beyond the core window and door line, the product range spans conservatories and orangeries, EPDM flat roofing and roof lanterns, tiled-roof and single-storey home extensions, fascias, soffits and guttering, and resin-bonded and block-paved driveways — positioning the business as a one-stop exterior renovation provider rather than a single-category tradesman.
The company operates a direct-to-consumer go-to-market model with free in-home consultations, on-site measurements, and custom project-based quotations, supported by a freephone number (0800 593 4700), a website with quote-request functionality, and a Facebook presence. Five physical locations — Romford headquarters and factory, plus regional offices in Chelmsford, Milton Keynes, and Lowestoft — support service delivery across seven UK regions: Essex, Kent, London, Suffolk, Cambridge, Berkshire, and Surrey. All products are made to order and installed by in-house specialist tradespeople, with a 10-year Zenith Guarantee on every installation, Secure by Design and Certass compliance certifications, and a reported 4.7 out of 5 Google Reviews rating from 60 customer reviews.
Revenue is generated entirely through one-off project contracts (no subscription or recurring component), with pricing determined per-project after consultation. The customer base consists exclusively of individual residential homeowners across the South and East of England, with no enterprise, B2B, or trade-channel revenue disclosed. The company is independently owned with no external investors, parent entity, subsidiaries, or funding rounds disclosed in available materials.

Zenith Windows competitors and assessment
Company assessmentEmerging players
- Apeer Doors: UK-based specialist composite door manufacturer and supplier. Comparable as a direct peer in Zenith's door category with overlapping trade customers and similar security/durability value propositions.
- Conservatory Outlet: UK manufacturer and retailer of conservatories, orangeries, and home extensions. Directly overlaps with Zenith's conservatory, orangery, and extension product lines.
Direct peers
- Safestyle UK: UK's largest pure-play uPVC window and door replacement company with a national D2C sales force and installer network. Closest direct competitor on Zenith's core windows/doors product line and D2C GTM motion.
- Zenith Staybrite Windows: UK-based D2C home improvement company offering windows, doors, and conservatories with in-home consultations. Highly comparable family-run regional model targeting similar homeowner demographics.
- TradeMark Windows & Doors: UK uPVC window and door fabricator and installer serving trade and retail customers. Comparable product offering and installer business model.
- CR Smith: Scottish family-run home improvement manufacturer and installer of windows, doors, and conservatories with in-house production. Closely comparable vertically-integrated, family-run D2C model, though concentrated in Scotland rather than SE England.
- Anglian Home Improvements: UK's largest home improvement company offering windows, doors, conservatories, roofing, and driveways through a direct-to-consumer sales model with in-home consultations. Directly comparable product portfolio, sales motion, and target customer (UK homeowners), though at significantly greater national scale.
- Everest Home Improvements: Major UK home improvement company offering windows, doors, conservatories, and roofing with in-home sales consultations and professional installation. Competes head-to-head with Zenith in the same product categories and D2C motion.
Broad incumbents
- Hillarys: Established UK D2C home improvement company primarily selling blinds, shutters, and curtains via in-home consultations. Comparable D2C motion and homeowner-targeted consultative sales approach.
- Wickes: UK home improvement retailer offering kitchens, bathrooms, and building materials including doors and windows. Adjacent rather than directly competitive — serves the same homeowner customer via a different (retail/DIY) channel.
