Frequently Asked Questions
1. Do your products come with a warranty?
Yes, all Gradwell Group products come with a manufacturer’s warranty for your peace of mind. Warranty periods vary depending on the product type, but most of our aluminium and GRP ranges offer 10–25 years of coverage against structural defects, corrosion, or weathering.
2. Can you deliver anywhere in the UK?
Absolutely. We offer UK-wide delivery on all products, including large or heavy items such as carports, patio covers, and conservatories. Delivery times may vary based on location and product availability, but we’ll always keep you updated every step of the way.
3. Do I need planning permission for your products?
In most cases, our products do not require planning permission—especially for carports, door canopies, patio covers, and roofline items. However, we always recommend checking with your local planning authority for large installations or if you live in a conservation area or listed building. Our team can provide specifications to assist with your application if needed.
4. Can I install the product myself or do I need a professional?
For larger structures like aluminium carports or lean-to conservatories, we recommend using a qualified installer for best results. We can also arrange professional installation services through our trusted partners.
5. How do I choose the right size or style for my property?
Our team is here to help! If you’re unsure which product suits your space, simply get in touch with us. We can guide you through measurements, fitting options, and customisation features to ensure you get the perfect fit—whether it’s for your garden, driveway, or roofline.
