## Frequently Asked Questions

**Q: Do I need planning permission for a conservatory?**
A: Most conservatories fall under permitted development and don't require planning permission, as long as they meet certain size limits. We'll advise you on this during your free survey.

**Q: How long does a conservatory installation take?**
A: Most conservatory installations are completed within 3–7 days, depending on size and complexity. We'll give you a clear timeline when we quote.

**Q: What's the difference between a conservatory and an orangery?**
A: A conservatory is predominantly glazed, while an orangery features solid walls with glazed sections — creating a more solid, room-like feel. Both add valuable living space and value to your home.

**Q: Do you offer a guarantee on your work?**
A: Yes. Every installation we carry out is backed by our 10-year insurance-backed guarantee, giving you complete peace of mind.

**Q: Can I get a quote without any obligation to proceed?**
A: Absolutely. Our free site survey comes with no obligation whatsoever. We'll visit, measure up, and provide a clear written quote — you decide from there.
