Rockdoor Approved Installer – Derby & the Midlands
The UK’s most secure composite door, expertly installed across Derby, Nottingham, Leicester and the Midlands. With 2,000+ Rockdoors fitted since 2010, we’re one of the most experienced approved installers in the region. From £1,700 fully fitted including VAT.

Why Choose Very Secure Doors for Your Rockdoor?
When investing in a Rockdoor, the quality of installation is just as important as the door itself. We’re one of the UK’s most experienced Rockdoor approved installers, with over 2,000 doors fitted across the Midlands since 2010. Here’s why homeowners trust us with their Rockdoor installation.
Rockdoor Approved Installer
Very Secure Doors is officially approved by Rockdoor – a status only granted to installers who meet their strict standards for expertise, customer service and installation quality. This means every door is fitted to manufacturer specifications, your warranty is fully protected, and you’re dealing with a company Rockdoor trusts to represent their brand.
Unlike many composite door companies who work with networks of subcontractors, we handle everything in-house. From your initial quote to the final installation, you’ll deal directly with Jim and Josh – a father and son team who take personal pride in every Rockdoor we fit.
Over 2,000 Rockdoors Installed Since 2010
With 15 years of dedicated Rockdoor installation experience, we’ve seen every type of property, every fitting challenge, and every customer requirement. From Victorian terraces in Derby to modern new-builds in Nottingham, we’ve installed Rockdoors that perfectly suit each home’s architecture and security needs.
This experience means we can advise on the best style for your property, anticipate any fitting complications during our free survey, and complete installations efficiently – typically within one day. We know Rockdoors inside and out, and it shows in the finished result.
Family-Run Business with In-House Installation
Very Secure Doors is a family business, and we treat every installation as if it were our own home. There are no salespeople, no pushy tactics, and no anonymous subcontractors turning up on installation day. When you contact us, you’ll speak directly with the people who will fit your door.
We cover the entire process ourselves – from the initial survey and accurate quotation, through to professional installation and aftercare. This means better communication, faster response times, and complete accountability. If you have a question about your Rockdoor in six months’ time, you’ll speak to the same people who fitted it.
Fast Lead Times and Professional Service
We understand that replacing your door is often time-sensitive, whether you’re addressing a security concern or coordinating with other home improvements. Our typical lead time from order to installation is just 5 weeks, and we offer free surveys 7 days a week to fit around your schedule.
During installation, we take exceptional care of your property. Old doors are removed carefully to minimise damage to surrounding brickwork and frames. The work area is protected, and we leave your home clean and tidy with all debris removed. Our Google reviews consistently mention our respect for customers’ homes and the professional finish we deliver.
What Makes Rockdoor the UK’s Most Secure Composite Door?
Rockdoor isn’t just another composite door brand – it’s engineered to be the most secure residential door you can buy. Through innovative construction methods and premium materials, Rockdoor composite doors offer unmatched protection against forced entry, superior energy efficiency, and exceptional durability. Here’s what sets them apart.
Unbeatable Strength: 35% Stronger Than Standard Composite Doors
While most composite doors use a foam-filled core, Rockdoor goes further with a high-density polyurethane foam core that’s 35% stronger than standard alternatives. This increased core strength, combined with an aluminium-reinforced inner frame and reinforced uPVC skins, creates a door that simply cannot be forced open.
This isn’t just marketing – Rockdoor famously earned the nickname “the door that beat the bobbies” after police couldn’t breach it with battering rams during testing. For homeowners concerned about security, this level of protection provides genuine peace of mind.


S-Glaze Technology: Permanently Sealed Glass
Traditional composite doors use clip-in glazing systems that can be removed by determined intruders, creating a weak point in an otherwise secure door. Rockdoor’s exclusive S-Glaze technology permanently seals the glass unit into the door structure itself during manufacturing.
This eliminates the glazing aperture as an entry point and dramatically improves thermal efficiency by preventing draughts around the glass. The result is a door with no weak spots and superior energy performance compared to standard composite doors.
Advanced Locking and Security Features
Every Rockdoor comes with a multi-point locking system featuring nickel-coated solid brass hook locks, German-engineered mechanisms, and a 3-star anti-snap cylinder as standard. The steel-reinforced uPVC frame provides additional strength around the lock area – the most vulnerable point on any door.
Rockdoor composite doors meet Secured by Design standards and are PAS 24 accredited, meaning they’ve passed the police-approved standard for security. With 70% of home break-ins occurring through the front door, investing in a Rockdoor significantly reduces your property’s vulnerability.


Exceptional Energy Efficiency
Beyond security, Rockdoor composite doors deliver outstanding thermal performance. The combination of high-density foam core, reinforced construction, and S-Glaze technology creates a door with superior insulation properties. Most Rockdoors achieve U-values well below Building Regulations requirements, helping to reduce your energy bills and keep your home comfortable year-round.
The robust construction also means excellent sound insulation, making Rockdoor an ideal choice for properties on busy roads or in urban areas where external noise is a concern.

Rockdoor Styles, Colours & Customisation Options
One of Rockdoor’s greatest strengths is the ability to create a door that perfectly matches your home’s character while maintaining exceptional security. With over 25 distinctive styles, 14 colour options, and exclusive 3D glass designs, you can design a Rockdoor that’s uniquely yours. Whether you’re looking for traditional elegance or contemporary minimalism, there’s a Rockdoor to suit every property.
Front Doors, Back Doors & Specialist Designs
Rockdoor offers styles suitable for every entrance to your home:
Front Doors – Create that perfect first impression with designs ranging from classic cottage styles to sleek modern aesthetics. Popular choices include the Vermont, Newark, and English Cottage, each offering large glazed areas for natural light while maintaining security.
Back Doors – Prioritise privacy and security with backing glass options and robust designs. Many Rockdoor styles work beautifully as back doors, with obscured glazing patterns that prevent visibility while still allowing light through.
Stable Doors – Combine traditional charm with modern security. Rockdoor stable doors feature independently opening top and bottom sections, perfect for letting fresh air in while keeping children and pets safely inside.
French Doors – Several Rockdoor styles can be configured as French doors, providing wide openings to gardens and patios without compromising on security. Each door is individually reinforced and fitted with multi-point locking.






Popular Rockdoor Styles
While every Rockdoor style offers the same exceptional security and build quality, these five designs are consistently popular with our Midlands customers:
Vermont – A contemporary design featuring bold, clean lines and generous glazing. Perfect for modern properties and new builds, the Vermont works particularly well with anthracite grey or slate finishes.
Newark – Classic elegance with traditional panel detailing. The Newark suits period properties beautifully and is a favourite for Victorian and Edwardian homes across Derby and Nottingham.
Jacobean – Timeless cottage styling with authentic detailing. This style complements older properties while delivering 21st-century security and energy efficiency.
English Cottage – Traditional charm with diamond leaded glazing options. Ideal for character properties where aesthetic authenticity matters as much as security.
Vogue – A statement design with a large central glass panel that showcases Rockdoor’s stunning 3D glass designs. The Vogue suits contemporary and traditional homes alike, and can be configured as French doors.
13 Colours with 169 Possible Combinations
Rockdoor offers 13 carefully selected colours throughout their range, from classic White and Rosewood to contemporary Anthracite Grey and Slate Grey. What makes this even more versatile is that you can specify different colours for the internal and external faces of your door.
This dual-colour option creates 169 possible combinations, allowing you to match your door’s exterior to your home’s facade while coordinating the interior with your hallway décor. Popular combinations in the Midlands include Anthracite Grey external with White internal, or Chartwell Green external with Light Oak internal.
Colours available: White, Cream, Light Oak, Rosewood, Irish Oak, Black, Red, Blue, Green, Chartwell Green, Anthracite Grey, Slate Grey, Agate Grey and Pebble Grey














Exclusive 3D Glass Designs & Hardware Options
Rockdoor’s decorative glass designs are exclusive to the brand and feature genuine three-dimensional textures and bevelling – not flat printed patterns. From contemporary geometric designs like Cube and Shade to traditional styles like Jubilee and Diamond Lead, there are dozens of glass options to personalise your door.
Hardware choices include premium bar handles, traditional lever handles, and a range of letterplates, knockers, and numerals in chrome, gold, and black finishes. All hardware is designed to complement Rockdoor’s security features while adding the finishing touches to your door’s appearance.

Rockdoor vs Other Composite Doors: How Do They Compare?
Choosing the right composite door brand is just as important as choosing the right style. While all composite doors offer improvements over traditional timber or uPVC, there are significant differences in construction quality, security features, and long-term performance between manufacturers. Here’s how Rockdoor compares to the main alternatives homeowners consider.
Solidor is Rockdoor’s closest competitor in the premium composite door market, and both represent excellent choices compared to standard alternatives. However, there are key differences worth considering:
Both brands use different materials for their core, however they are significantly stronger than standard composite doors. Rockdoor’s core is 50mm thick compared to Solidor’s 44mm, providing marginally better insulation and impact resistance. Rockdoor’s exclusive S-Glaze technology permanently seals the glass, whereas Solidor uses high-quality but still removable glazing cassettes.
Both brands exceed Secured by Design standards and feature multi-point locking systems with anti-snap cylinders. Rockdoor’s reputation as “the door that beat the bobbies” came from independent police testing where battering rams couldn’t breach it. Solidor doors are also exceptionally secure, though they haven’t undergone the same high-profile testing.
Both offer 10-year guarantees and sit in a similar price bracket. Rockdoor typically costs slightly more due to the S-Glaze technology and thicker core construction. For most homeowners, the choice between Rockdoor and Solidor comes down to specific style preferences and which approved installer serves their area.

Rockdoor vs Standard GRP Composite Doors
This is where the difference becomes more significant. Standard GRP (glass-reinforced plastic) composite doors are the most common type found on the market and represent a considerable step up from uPVC or timber. However, Rockdoor’s construction puts it in a different category entirely:
Standard GRP composite doors typically use a lower-density foam core. Rockdoor uses high-density polyurethane foam with aluminium reinforcement, making it 35% stronger than standard alternatives. This translates to better impact resistance and forced entry protection.
Most GRP composite doors use clip-in glazing beads that can be removed from outside with the right tools, creating a security vulnerability. Rockdoor’s S-Glaze system eliminates this weakness entirely by sealing the glass permanently into the door structure during manufacturing.
While many GRP doors achieve acceptable U-values, Rockdoor’s denser core and sealed glazing system deliver superior insulation. This means lower energy bills and better protection against draughts, particularly around the glass area where standard doors often perform poorly.
Lower-quality GRP doors can fade, discolour, or develop surface cracks within 5-10 years, particularly on south-facing properties. Rockdoor’s thicker, higher-quality skins resist UV damage and maintain their appearance for decades.
Standard GRP composite doors typically cost £1,000-£1,500 fitted, while Rockdoors start from £1,700. The £200-£600 premium buys substantially better security, energy efficiency, and a door that will last twice as long without deterioration.
Which Composite Door is Right for You?
The honest answer is that it depends on your priorities and budget:
Choose Rockdoor if: Security is your primary concern, you want the proven track record of police-tested protection, and you appreciate the benefits of permanently sealed glazing. Rockdoor offers the best balance of security, thermal performance, and long-term value. It’s particularly suited to properties in urban areas, homes with higher insurance requirements, or homeowners who simply want the best available protection.
Choose Solidor if: You prefer their specific style options, you’re served by a highly-rated Solidor installer, or you’ve found a competitive price. The performance difference between Rockdoor and Solidor is marginal – both are premium choices that will serve you excellently for decades.
Choose Standard GRP if: Budget is tight, you’re replacing a door on a rental property, or security isn’t a primary concern (perhaps for a back door to a fenced garden). Modern GRP composite doors are still far better than old timber or uPVC and represent good value at their price point.
As a Rockdoor approved installer, we naturally believe Rockdoor offers the best combination of security, quality, and value. However, we also supply GRP composite doors for customers who prefer a more budget-friendly option without compromising too much on quality.
Our Rockdoor Installation Process
A Rockdoor is only as good as its installation, which is why we handle every stage ourselves with meticulous care and attention to detail. From your initial enquiry through to aftercare, you’ll deal directly with Jim and Josh – no salespeople, no subcontractors, no surprises. Here’s exactly what to expect when you choose Very Secure Doors for your Rockdoor installation.
Step 1: Free Survey and Accurate Quotation
Every Rockdoor installation begins with a free, no-obligation quote by email. We then arrange a survey and offer appointments 7 days a week to fit around your schedule, including evenings and weekends.
During the survey, we’ll take precise measurements of your existing door opening, assess the condition of your current frame and brickwork, and discuss your requirements in detail. This is your opportunity to ask further questions about styles, colours, glass options, and hardware choices.
Unlike high-pressure sales companies, we won’t sit in your home for hours or use pushy tactics. The survey typically takes 10-30 minutes, and we will update your quote and send it to you by email with any changes discussed. This quote is completely transparent with no hidden costs – what we quote is what you pay.
If you’re happy to proceed, we’ll place your order with Rockdoor. If you need time to think or want to get alternative quotes, that’s absolutely fine. There’s no pressure and no follow-up calls unless you request them.
Step 2: Manufacturing and Preparation (3-5 Weeks)
Once you’ve confirmed your order, your Rockdoor goes into production at Rockdoor’s UK manufacturing facility. Each door is custom-made to your exact specifications – size, style, colour, glass design, and hardware are all built specifically for your property.
Typical lead time from order to delivery is 3-5 weeks, though this can vary slightly depending on the time of year and your specific configuration. We get an estimated delivery date upon ordering, and we email you several installation dates for you to choose.
We understand that having work done on your home needs to fit around your commitments, so we’re flexible with scheduling and will always arrive when we say we will.
Step 3: Professional Installation Day
Installation typically takes one working day for a standard single door, though more complex configurations with sidelights or unusual frames may take longer. We’ll give you a clear timeframe when booking your installation date.
What happens on installation day:
We arrive on time with all necessary tools, materials, and protective equipment. Before we start, we’ll protect your flooring, hallway, and any furniture near the work area with dust sheets and coverings.
Your old door is carefully removed to minimise damage to surrounding brickwork and plasterwork.
The new Rockdoor is fitted precisely, ensuring it’s perfectly square, level, and sits correctly in the opening. This is critical – even the best door will perform poorly if fitted badly. We take time to get this right, adjusting and checking multiple times before final fixing.
Once the door is secure, we fit all hardware, adjust the multi-point locking system for smooth operation, and test everything thoroughly. We’ll make final adjustments to hinges and locks to ensure the door closes perfectly and locks smoothly every time.
All debris, packaging, and your old door are removed from site. We leave your property clean and tidy, and all hoovered. You’ll never know we were there apart from your beautiful new Rockdoor.
Step 4: Aftercare and Ongoing Support
Before we leave, we’ll show you how to operate your new Rockdoor, explain the locking mechanism, and provide care and maintenance advice. You’ll receive all keys (three as standard).
Your Rockdoor comes with a 10-year manufacturer warranty covering any defects in materials or workmanship. We provide ongoing aftercare support for the lifetime of your door.
If you experience any issues – however minor – we’re just a phone call away. As the company who fitted your door, we take responsibility for sorting any problems quickly and efficiently. This is one of the key advantages of using a small family business rather than a large franchise – you’ll always speak to someone who knows your installation and cares about getting it right.

Here are some recent installations and the customers who trusted us with their home security.
Why Installation Quality Matters
As we often tell customers: an excellent door fitted badly will always be a bad door. Unfortunately, we’ve seen this first-hand when called to remedy poor installations by other companies.
Common installation problems we’ve encountered include:
These issues aren’t failures of the door itself – they’re failures of installation. This is why we insist on doing all our work in-house rather than subcontracting. When you choose Very Secure Doors, you’re not just buying a Rockdoor – you’re buying 15 years of installation expertise and a team who take personal pride in every job.
Rockdoor Supply Only (UK-Wide)
While our expertise is in professional installation across the Midlands, we also supply Rockdoor composite doors UK-wide for customers who have their own trusted installer or prefer to arrange fitting separately. We provide the same quality doors with full manufacturer warranty and technical support.
Quick and Easy Quotations
We offer same-day quotations for supply-only Rockdoor orders. Simply contact us with your requirements – style, size, colour, glass design, and hardware – and we’ll provide an accurate price within hours. All quotations are transparent with no hidden costs.
Competitive Supply-Only Pricing
Supply-only Rockdoor prices start from approximately £1,200 depending on your specification. This includes the complete door with your chosen style, colour, glass design, multi-point locking system, and hardware. Final pricing depends on the same factors as fitted doors – decorative glass, premium hardware, and frame configuration all affect the total cost.
Direct Delivery Across Mainland UK
We arrange direct delivery to your door anywhere in mainland UK. Doors are securely packaged to prevent damage in transit and come with full installation instructions. Lead times for supply-only orders are typically 3-5 weeks from order confirmation, though this can vary depending on specification and time of year.

Important: If you’re located within our installation area (Derby, Nottingham, Leicester, Burton, Warwick, or surrounding Midlands regions), we strongly recommend choosing our professional installation service.
A Rockdoor is only as secure and efficient as its installation. Our 15 years of experience, in-house fitting, and personal accountability ensure your door performs exactly as Rockdoor designed it to. Supply-only is best suited for customers outside our service area or those with professional installers they already trust.
