Composite Front Doors
Our composite front doors combine multiple materials for exceptional strength and security. Designed with high-density foam cores and GRP skins, they resist weathering and fading while offering U-values as low as 1.0 for energy efficiency. Available in traditional and modern styles with custom colours and hardware, these doors enhance property aesthetics and value. The integrated PAS24-approved locks and TS007 cylinders provide robust protection against forced entry.
FD30 Fire Doors
FD30 fire doors provide 30 minutes of fire resistance, tested to BS 476-22 standards. Designed for internal and external use, they feature intumescent seals that expand under heat to block smoke and flames. Constructed with solid timber cores and reinforced frames, these doors meet building regulations for safety in residential and commercial properties while maintaining thermal efficiency and aesthetic flexibility.
UPVC Back Doors
UPVC back doors offer a cost-effective alternative to composite doors, featuring double-glazed panels for natural light and thermal insulation. Available in full or partially glazed options with MDF-reinforced panels, they include multipoint locking systems for security. These low-maintenance doors come with a 10-year guarantee against warping and are ideal for modern or traditional homes requiring durable, energy-efficient solutions.
Timber Composite Doors
Solidor timber composite doors blend traditional aesthetics with modern engineering, featuring 48mm solid hardwood cores for superior strength. The GRP cladding resists fading, while the TS007 3-star cylinders and hook locks ensure security. Available in traditional and contemporary designs, these doors offer dual-colour finishes and a 10-year warranty, combining elegance with long-term performance.
Composite Stable Doors
Composite stable doors provide a classic bifolding design with enhanced security features. Constructed from weather-resistant GRP and reinforced frames, they include dual locking points and thermal insulation. Ideal for modern and period properties, these doors allow ventilation while maintaining security, available in traditional white or contemporary colours to match property exteriors.

Ordering from GRP Composite Doors was incredibly straightforward. Payment wasn't required initially. By 9 am the following day, a representative reached out to review the order details, ensuring precision and clarity on every dimension while also offering guidance on suitable hardware. The door arrived promptly the next Monday, impeccably packaged, without any damage to the slab or frame. It fit perfectly into the measured opening, aligning well with their measuring guidelines. The color is fantastic, and since the initial fitting, there hasn't been any need to adjust the hinges.

The front door I ordered came exactly as requested. A very quick service from GRP, received a telephone call arranging delivery & payment within minutes of placing the order. It was delivered on the agreed date & time and was well packaged for protection.

I found the website simple and intuitive to design my perfect door. Plenty of options to ensure the design was as required. Delivery was taken in under 7 days, with a prearranged 2hr time slot which was kept to. The product was faultless, well packaged and exactly to the specification. I installed the door/frame in a few hours with no problems using the instructions supplied. Will definitely use again and would recommend to others. Thanks!

Measured up, loaded dimensions and made necessary selections. Had one question, about backing glass pattern, rang office to clarify and this was dealt with in a friendly and efficient manner. Door delivered, as quoted, with no problems although the delivery is to door only and not inside. Fitted the following day without problems. Door looks good and wife is pleased, who could ask for more? Highly recommended and all that have seen it have made positive comments.

Best price I could find, included delivery, contacted us to confirm all the details and were spot on with the delivery time slot. Very good. A small scratch in the colour upon delivery which they sent a free touch up out in the post. The graphite colour hardware is actually more like a dark satin chrome which is actually exactly what we wanted.

Following Returning from a weekend away to find our existing door faulty I urgently needed a replacement. I found GRP online and so created a door design of our choice which we thought was a great way of visualising it. I placed the order that night and got a phone call the following day to go through the order. Order placed paid for and delivery arranged for 2 weeks later. I was very impressed by this point in my experience with the these guys.

As advised we received a call confirming delivery the day before and sure enough they arrived well within the given time slot. So I have now installed our new door and I have to say it looks Amazing! I highly recommend this company and I will be sure to use them again in the future for my side door. All that's left to say is THANK YOU

Every thing went well from ordering to delivery and finally me using my old carpentry skill to install the door set. The instruction for fitting, adjusting the hinges and general caring for the door were clear and easy to understand.

All communication was excellent, staff very helpful and informative. Delivery was super quick and earlier than expected. Got a phone call 15 minutes prior to arrival. I was late getting to the delivery address and the guys waited no problem. The guy who installed the doors (my tradesman) said they were excellent quality and easy to fit. Both doors fitted by one man in 4 hours including removing old doors. The tradesman could hardly believe the price I paid compared to suppliers he uses. Very please highly recommended.

Excellent wooden core door, just as good as a more expensive make we also have fitted to the house. Ordering was simple, everything was double check by them before proceeding. And the lead time was excellent, had the door inside of 10 days which was when I needed it to be delivered!

Excellent service. The door configurator is easy to use, I checked my measurements with the sales team by sending in a photo of where I was taking the measurements from (tells you online but I double checked). Confirmed my details with the sales team and within 5 days, the door arrived. We went for the premium door, it's definitely a solid door, it took 2 of us to put it in place. Easily fitted by a professional door fitter. I would definitely recommend this company.

Ordered a replacement front door from GRP Composite Doors. Prices were the best I could find online, the ordering process was thorough but straightforward with plenty of options. Upon completion of the order I received a phone call from them to confirm the order and let me know when delivery will be made which was very accurate.
Fitted door looks great, is very solid and secure and fitted as it should. Highly recommended.

Very good quality doors, arrived in good time. Smell of fibreglass for a few months when in sun but eventually wore off.
