“Extremely professional, excellent workmanship, great job.”



What a difference new windows make to a house

…no hard sell, just giving the facts. It was not a straightforward new windows situation there was some brick work to deal with. This was no problem and was dealt with amazingly well, now we have a whole new look to our home.



Incredibly impressed with the various teams involved

We felt it was very important to let the guys at Oakley green know how incredibly impressed we are with the various teams who worked on the project.

It has made such a difference to our home. A big thank you to the Oakley Green Conservatories team, we would thoroughly recommend them.



We now have a beautiful tiled roof Garden Room

We love our new room in the Summer but to get the sun in the Winter streaming through the french doors is lovely.



From start to completion the service provided was excellent

The tradesmen were polite and professional and nothing was too much trouble. I would have no hesitation in using your services again.

Oakley Green have just finished my conservatory and I’m thrilled with the results.



All the team were very friendly and professional

The guys that installed the windows worked hard to finish it in one day and left everything clean and tidy.

Every aspect of the build we could not fault

I would like to mention Maurice whom we thought was excellent in his approach to advising us and giving us the benefit of his greater knowledge.

Looks great – sold on quality

I already enjoy watching the sunset in my gorgeous new space. The kids love the easy access to the garden, and I can relax watching them play.



Using Oakley Green was an excellent decision

We recently moved to Berkshire – we intended to contact a national conservatory firm, however our neighbours had all recommend Oakley Green.

I am absolutely thrilled with our garden room

It’s gone from a dated conservatory to a beautiful room we can use all year round and I love my glass panels in the roof.



So pleased with our new room!

It really is just as we had imagined. Friendly and conscientious trades people who cheerfully delivered a quality result in the most challenging of spaces due to difficult access. Love it! 🙂
