Window Installation in the UK: A Blend of Choices and Costs
In the United Kingdom, installing new windows is a complex process influenced by various factors. It's like weaving a tapestry where a homeowner's preferences mingle with elements like the type of window, its size, the materials used, how it's installed, and where the house is located. This creates a wide range of costs, with the average price for new windows varying from £600 to £3,600 per window. Why Such a Wide Cost Range? This diversity in costs stems from different needs and desires. For instance, replacing a small double-glazed casement window in a bathroom or utility room can be as low as £200. But if you're considering larger windows in important rooms like the living room or bedroom, the cost can range from £400 to £600. If you prefer wooden frame windows over practical uPVC ones, the price can easily double. And if you opt for rare wood types, the cost can soar into the thousands for a single window.
