This covers the window itself, frame, installation labour, removal of the old window, and FENSA certification.<\/p>\n\n\n\n<p>However, that figure is just an average \u2014 real prices depend on five things: the material (uPVC, aluminium, wood, composite), the style (casement, sash, tilt and turn, bay), the size, your region, and whether your property has access complications.<\/p>\n\n\n\n<p>The best way to know what <em>your<\/em> windows should cost is to get quotes from 3\u20134 independent FENSA-registered installers and compare. That&#8217;s exactly what <a href=\"\/glazing\/index.php\/quote\/\">our free comparison tool<\/a> is built for.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Cost by window material<\/h2>\n\n\n\n<p>Material is the single biggest cost driver. uPVC is cheapest (and still the UK&#8217;s most popular choice). Aluminium is mid-range. Hardwood and composite are premium.<\/p>\n\n\n\n<figure class=\"wp-block-table\" style=\"border-radius:8px\"><table>\n<thead><tr><th>Material<\/th><th>Per window installed<\/th><th>Durability<\/th><th>Maintenance<\/th><\/tr><\/thead>\n<tbody>\n<tr><td><strong>uPVC<\/strong><\/td><td>\u00a3450 \u2013 \u00a3900<\/td><td>25\u201335 years<\/td><td>None<\/td><\/tr>\n<tr><td><strong>Aluminium<\/strong><\/td><td>\u00a3650 \u2013 \u00a31,200<\/td><td>30\u201345 years<\/td><td>Minimal<\/td><\/tr>\n<tr><td><strong>Wood (softwood)<\/strong><\/td><td>\u00a3700 \u2013 \u00a31,300<\/td><td>15\u201325 years<\/td><td>Repaint every 5\u20138 yrs<\/td><\/tr>\n<tr><td><strong>Wood (hardwood)<\/strong><\/td><td>\u00a3800 \u2013 \u00a31,500<\/td><td>40\u201360 years<\/td><td>Repaint every 8\u201312 yrs<\/td><\/tr>\n<tr><td><strong>Composite<\/strong><\/td><td>\u00a3900 \u2013 \u00a31,800<\/td><td>50+ years<\/td><td>Minimal<\/td><\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n<p><strong>uPVC<\/strong> dominates ~80% of the UK replacement market because it&#8217;s affordable, well-insulated, and maintenance-free. The main downside is aesthetics \u2014 cheap uPVC can look plasticky on a period property.<\/p>\n\n\n\n<p><strong>Aluminium<\/strong> has slimmer sightlines, which matters for modern or minimalist homes. It&#8217;s stronger than uPVC and allows for larger panes. Slightly worse thermal performance than top-tier uPVC, though modern thermal-break aluminium closes the gap.<\/p>\n\n\n\n<p><strong>Wood<\/strong> is the only option allowed in most conservation areas and listed buildings. Hardwood lasts decades but needs periodic repainting. Softwood is cheaper upfront but has a shorter lifespan.<\/p>\n\n\n\n<p><strong>Composite<\/strong> (wood inside, aluminium outside) is the premium choice \u2014 best thermal performance, lowest maintenance, longest lifespan.

Avoid September\u2013November, when demand peaks ahead of winter.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Ask about ex-showroom stock<\/h3>\n\n\n<p>Installers sometimes have cancelled-order windows or showroom models available at 20\u201340% off.
