Energy Efficient

Our decorative super-insulated columns provide high levels of comfort and have a U-value of only 0.15 W/m²K. Our slimline ridges are 30% slimmer than traditional ridges and come with high-performance thermal breaks to prevent cold spots and condensation.

Structural Integrity

Our conservatory roofs are BBA-approved and come with a 25-year life expectancy certificate. They have been wind-tested at speeds of up to 130mph and fire-tested by Warringtonfire. Our roofs are also capable of withstanding up to 4m of unsupported bifold or sliding doors.

Internal Pelmet

Our conservatory roofs consist of a vaulted ceiling and have an internal pelmet around the perimeter. This provides a space for you to install lights or speakers in a living space that is usually difficult to light.


Exova Warringtonfire tests our conservatory roofs to ensure compliance with fire safety. Our conservatory roofs also fully comply with the latest Building Regulations and have been pre-approved by Assent and JHAI.

Frequently Asked Questions

Why should I have a cornice on my bespoke conservatory?

A cornice is ideal for your bespoke conservatory as it will add a polished, professional, and beautiful touch as cornices hide any unsightly guttering on your bespoke conservatory.

Can I use decorative glass on my bespoke conservatory?

Yes, you can. We offer various decorative glazing options for our bespoke conservatories, including custom and classic designs. We also provide leading for your bespoke conservatory.

What is the best material to use for a bespoke conservatory?

This depends on your objective. If you have a limited budget but don’t want to compromise on quality, then uPVC is an excellent choice for a bespoke conservatory due to its durability, longevity, customisation, and energy efficiency. 

Aluminium is more expensive, but less is needed to provide structural strength. This results in a bespoke conservatory that has less frame and more glass for a touch of beauty.

We also provide authentic timber bespoke conservatories that are ideal if your Littlehampton or West Sussex property is listed or is part of a protected area.

How much are bespoke conservatories?

It is difficult to provide a price for your bespoke conservatories as the material you choose, estimated fitting time, and other factors contribute to the overall costs. The best way to get a price is to call us at 01903 723362.
