Why Choose a Conservatory?
Add a Beautiful New Room to Your Surrey Home
A conservatory is one of the most popular ways to add both living space and real estate value to a home in Surrey. Whether you want a light-filled dining room, a quiet home office, a children's playroom, or a social kitchen-diner, there is a conservatory style designed specifically for your needs.
We install all 18 conservatory styles — from a simple lean-to for a bungalow to a premium bespoke orangery with roof lantern. Every conservatory we build in Caterham and across Surrey is manufactured to your exact measurements and installed by our experienced in-house team.
Every project starts with a free home survey — we measure up, assess your garden and planning position, and provide a detailed written quotation with no hidden extras.

Customer Reviews
What Our Conservatory Customers Say
“Our Victorian conservatory has absolutely transformed the back of the house. It is genuinely the most-used room in the home now — summer and winter. The team were meticulous from start to finish.”
KB
Karen & Steven Bright
Caterham, Surrey
“I went for an orangery after spending weeks looking at options. The difference compared to our old lean-to is incredible — it genuinely feels like part of the house rather than a glass box. Highly recommend.”
JW
James Whitmore
Warlingham, Surrey
“We had an Edwardian 4m x 3.5m installed. The floor space is brilliant — we have a dining table at one end and a sofa at the other. Ensure Windows were professional, communicative, and delivered exactly what they promised.”
