We used plantation shutters (yes that's their actual name) in Battersea business Park and they were great. Cost 3k for 5 rooms approx including fitting.

We have shutters from The Traditional Shutter Company and are really pleased. We got a few quotes but this is a local, family owned business and they own their factory so were able to be v competitive.

Having had our home newly renovated from top to bottom, we’re looking for recommendations on companies to fit plantation shutters. Not our forever home so focus is on reasonably priced... thanks in advance :)
