I don’t qualify for any double glazing grants – now what?If you don’t qualify for any double glazing grants, there are other ways to reduce costs. Here are just a few:Shop around and negotiate – Getting quotes from multiple double glazing installers will help you locate the best deal. Negotiating with the installers, though it might be awkward for some, can also lead to discounts. Don’t forget that installers want to make a sale, so the ball is really in your courtDon’t choose the most expensive materials and designs – Some window materials and designs are more expensive than others. In most cases, opting for casement windows with uPVC frames will be the cheapest option. Don’t overlook other factors such as decorative glazing bars – while they might look charming, more material always equals a higher costConsider if all your windows need to be openable – Fixed panes are cheaper than windows with hinges for opening, so consider which rooms you want openable windows in. In entrance halls or corridors for example, you might not need a window you can openOpt for windows with a lower energy rating – Windows have energy ratings that indicate how well they insulate a property. The best double glazed windows have a rating of A+++, but they’re also the most expensive. If you’re switching from single glazing to double glazing, you’ll still feel the benefits if you opt for double glazed windows with a B or A ratingHave your windows installed in winter – It’s cheaper to install new windows in the winter compared to the summer, because less people are doing it. Demand is low, and installers are eager for work, so you’re more likely to get a better deal. The cheapest time of year to install windows is early December, right before the Christmas holidaysHopefully these tips can help you reduce costs.
