These three names come up constantly once you start researching composite doors — and for good reason, they're among the most established brands in the UK market. Here's how they actually compare, without the marketing spin.
Solidor is one of the longest-established names in composite doors, known for a timber core construction rather than the foam-core approach some competitors use. This tends to give a heavier, more traditional feel, which is part of why it's popular for period and semi-detached properties across areas like Trafford and Stretford. Solidor also offers one of the widest colour and glazing ranges on the market, which is useful if you want a specific look rather than picking from a limited palette.
Distinction leans into a more contemporary design language — flush, minimal-panel styles are a big part of their range, which suits newer builds or homeowners doing a modern renovation rather than matching a period look. Distinction doors are also composite, but the styling and marketing are more geared toward architects and self-builders than the traditional homeowner replacement market.
Rockdoor puts a lot of emphasis on security certification (commonly citing Secured by Design and PAS 24 compliance across their range), and tends to sit at a slightly more accessible price point than Solidor or Distinction while still being a genuine composite door rather than a budget alternative. It's a reasonable middle-ground choice if security credentials and value matter more to you than an extensive style range.
All three are legitimate, well-established composite door manufacturers — you're unlikely to make a "wrong" choice on quality alone. The real deciding factors are style preference (traditional vs contemporary), how important a wide colour/glazing range is to you, and price. For most Manchester homeowners, the bigger factor in overall satisfaction is usually the installer's fitting quality, not which of these three brands you pick.
A great door badly fitted will underperform a good door properly fitted, every time.
Especially relevant for older Manchester properties with non-standard frame sizes.
Check who actually honours the guarantee if something needs adjusting later.
Neither is objectively "better" — Solidor suits a more traditional look with a wider colour range, while Distinction leans contemporary and minimal. The right choice depends on your home's style and your own preference.
No — Rockdoor is a genuine composite door manufacturer, not a budget alternative. It sits at a more accessible price point than Solidor or Distinction while still meeting standard composite door security certifications.
Ranges vary by brand and change over time, so it's worth checking current brochures — Solidor is generally known for having one of the widest colour and glazing options.
