What Three Counties does

Three Counties (legal entity: 3 Counties (Sandhurst) Ltd, Co No. 06502033) is a privately held, direct-to-consumer home improvement installer based in Camberley, Surrey, United Kingdom. Founded circa 2004 (with one source noting 2008) and operating for approximately 20 years, the company supplies and installs double- and triple-glazed windows, doors (composite, uPVC, aluminium, bifold, French, patio, stable), conservatories, orangeries, glass extensions, lantern roofs and roofline products across Surrey, Hampshire and Berkshire. Products are made-to-order to customer specifications through a curated network of 15+ premium UK and European manufacturers including Origin, Solidor, Ultraframe, Halo/VEKA, ALUK, Apeer, Smart Architectural Aluminium, Door-Stop, Atlas, Evolution, Victorian Sliders, Re-Aluminium, SupaLite and Guardian Roofs. Technical differentiators include A-rated Window Energy Rating performance, argon-filled sealed units, multi-point locking, and Kubu smart-home sensor integration (launched March 2024). The company is FCA-authorised as a credit broker (FRN: 727419) and holds FENSA, TrustMark, GGF, GGFi, Buy With Confidence and ICO registrations.

The business operates a showroom-and-field-sales distribution model, supported by an online Dynamic Price Engine for self-service guided quotes, Google Ads remarketing, content marketing (active blog), social channels (Facebook, Instagram, Pinterest, LinkedIn, YouTube) and a tiered referral programme (£50-£250 One4All vouchers). Revenue is generated primarily through one-time installation contracts with milestone-based payment schedules (50/50 for windows and doors; 25/40/25/10 for conservatories), plus transaction-fee commission from consumer finance arranged via Novuna Personal Finance (Mitsubishi HC Capital UK PLC), with finance products ranging from 0% deposit BNPL to 5-year interest-free credit on contracts up to £30,000. Customer segments are predominantly individual homeowners in South East England, with secondary targeting of landlords, HMO owners and property investors (driven by Minimum Energy Efficiency Standard compliance) and EV owners. Additional revenue streams include solar panel and battery storage installation and home EV charging point installation.

Direct peers

• Safestyle UK: Safestyle UK is the largest dedicated uPVC window and door installer in the United Kingdom, supplying and fitting replacement windows, doors, and conservatories to homeowners on a direct-to-consumer, finance-supported model. It is the closest direct peer to Three Counties given identical supply-and-install mechanics, energy-rated product focus, and reliance on consumer credit conversion.
• Zenith Staybrite Windows: Zenith Staybrite is a regional UK window, door, and conservatory installer with comparable supply-and-install, finance-supported, and Checkatrade-driven go-to-market mechanics. It is a near-direct peer to Three Counties in operating model, regional scale, and homeowner focus.
• Nationwide Windows & Doors: Nationwide Windows and Doors is a regional UK window and door installer with comparable made-to-order supply-and-fit operations and homeowner GTM. It is a direct regional peer whose service mix closely parallels Three Counties' window/door core, though its coverage is multi-region rather than three-county focused.

Broad incumbents

• Anglian Home Improvements: Anglian Home Improvements is the largest UK home improvements incumbent, offering windows, doors, conservatories, roofline, and driveways nationwide. It overlaps directly with Three Counties' core categories but operates as a national portfolio player rather than a regional specialist.
• Everest Home Improvements: Everest is a long-established UK home improvements incumbent offering double-glazed windows, doors, conservatories, and roofline products with nationwide coverage. It competes in the same product categories as Three Counties but at significantly larger national scale with proprietary (rather than third-party) frame manufacture.

Regional players

• CR Smith: CR Smith is a Scotland-based manufacturer and installer of windows, doors, and conservatories with a vertically integrated supply-and-fit model. Its product mix, energy-rated glazing focus, and local-regional GTM closely parallel Three Counties' approach, with the main difference being geographic territory.

Others

• Duraflex: Duraflex is one of the UK's largest uPVC and aluminium profile extruders supplying fabricators and installers nationwide. Although it is upstream rather than directly retail-competitive, it is a key ecosystem supplier in Three Counties' product stack and a comparable glass-and-glazing category player.
• TruFrame: TruFrame is a UK uPVC and aluminium window and door fabricator serving trade installers rather than end consumers. It is a comparable glass-and-glazing category participant that competes for installer mind-share and represents the trade-supply channel adjacent to Three Counties' direct retail model.
