As standard you will receive an ultra efficient ‘A’ rated window. Our latest casement windows utilise some of the most advanced double glazing on the market. Our windows easily exceed building regulations so you will have the peace of mind that you are installing the very best double glazing.

The eco energy plus window system has achieved a BFRC (British Fenestration Rating Council) Window Energy Rating of ‘A’, the highest achievable.

“This is the second property they have done for me now, and once again I’m so pleased with the result! I can’t recommend these guys enough! Craig and Lewis (the fitters) were extremely friendly, polite and very tidy workers. Great company and a great family business. If you have never bought double glazing before and a bit daunted by all the company’s out there you MUST call Sidcup Double Glazing. They are all very friendly and genuine.”

“It’s nice not to be subjected to pressure selling and ridiculous discounts, and to be offered a fair price for an excellent job.”
