Double glazing prices in Kingston upon Thames & Surbiton

Kingston upon Thames and Surbiton are two of the most densely populated residential areas in the Greater London / Surrey border zone — and the national double glazing companies are extremely active here. The large stock of Victorian and Edwardian terraces in Surbiton and the mix of 1930s semis and modern detached homes across New Malden, Tolworth and Chessington means there is a constant stream of homeowners being quoted for new windows and doors.

Here is the simple truth: their salespeople work on commission. The less discount they give you, the more money they personally earn. That means the first price they quote you is not the real price — it is the price that earns them the most commission. The real price, the one they will accept if you know how to ask, is almost always significantly lower. Use the free Bottom Line Price Checker above and see for yourself.
