Two Composite Door Ranges to Suit Every Budget
We offer two composite door options across Derby. Both include multi-point locking, a high-security cylinder, professional installation, old door removal, and a full manufacturer’s guarantee.
Rockdoor — From £1,500 Fitted
Rockdoor is the UK’s most secure composite door, built with a 360° aluminium-reinforced inner frame, S-Glaze sealed glazing, and Winkhaus multi-point locking as standard. It’s the door we fit most across Derby — popular with homeowners who want the best available security and build quality. Over 25 styles in 14 colours, with exclusive 3D glass designs you won’t find anywhere else.
Most Derby customers spend between £1,900 and £2,100 on a Rockdoor once colour, glass and hardware are chosen. For a full breakdown, see our Rockdoor pricing guide.
GRP Composite Doors — From £1,100 Fitted
Our GRP composite doors deliver genuine composite performance — solid foam core, GRP skin, multi-point locking, high-security cylinder — at a more accessible price. They’re a significant upgrade over uPVC and a smart choice for homeowners replacing a tired front or back door without stretching to a Rockdoor budget.
GRP doors are particularly popular as back doors across Derby, where they offer strong security at the best value.

Common Property Types We Fit in Derby
Most of our Derby work is on newer-build semi-detached and detached homes — the kind of properties you’ll find across Boulton Moor, Chellaston, Mickleover and the estates around Oakwood and Littleover. These properties typically have standard-sized single door openings, making them straightforward to survey and fit.
The most common job we do in Derby is replacing an original builder’s door — usually a basic GRP or uPVC door that came with the house — with a Rockdoor or higher-specification GRP composite. The difference in feel, security and appearance is dramatic. Builder’s doors are built to a budget, with lightweight panels, basic locks and minimal insulation. A composite door transforms the entrance entirely.
We also regularly fit composite doors on older properties across areas like Allestree, Duffield and Darley Abbey, where the period character of the house calls for a more traditional door style. The Rockdoor English Cottage and Rockdoor Jacobean are popular choices here, offering traditional charm with modern security.

Why are we competitively priced? We’re a family business working from home — no showroom, no sales commissions, no fleet of branded vans. Those savings go directly to our customers. We regularly hear from Derby homeowners who’ve been quoted significantly more by larger companies for the same door.

How It Works
Composite back doors offer incredible strength and security. Most break-ins happen through the back or side door of a house, so by choosing a composite door, you can rest assured that forced entry is virtually impossible. Extra security options, such as laminated glass, are available, providing even more protection for your home. Composite doors are also energy-efficient and low maintenance, making them a practical and stylish choice for any home.

Composite Doors Derby — FAQs
How much does a composite door cost in Derby?
Our GRP composite doors start from £1,100 fully fitted, and Rockdoor composite doors start from £1,500 fully fitted — both prices include supply, installation, VAT and removal of your old door. Most customers spend between £1,100 and £2,100 depending on brand, style, colour, glass design and hardware. For a full pricing breakdown, read our guide to composite door prices.
Which is better — Rockdoor or GRP?
Both are genuine composite doors with solid cores, multi-point locking and high-security cylinders. Rockdoor offers the highest security specification available — aluminium-reinforced frame, S-Glaze sealed glazing, and Secured by Design eligibility. GRP composite doors offer excellent performance at a lower price point and are a significant upgrade over uPVC. If security is your top priority, Rockdoor is the better investment. If budget is a factor, GRP delivers outstanding value. We install both and can advise which suits your home and priorities — see our Rockdoor vs Solidor vs Endurance comparison for a detailed brand breakdown.
How long does it take to fit a composite door in Derby?
Installation takes a single day — typically 3–4 hours for a straightforward single door replacement. The overall process from enquiry to fitted door takes around 5 weeks, which includes design, survey, manufacture and fitting. For Derby addresses, we can usually arrange a survey within a few days of you confirming you’d like to go ahead.
