How Installing Energy-Efficient Windows in London Saves You Money

Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to make the switch:

• Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In London, that's about 525 pounds per year on average.
• Save money on power bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll require less energy to heat or cool your home.
• Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
• Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its real estate value.

Estimated Cost of Window Replacement in London

Windows come in different styles, shapes and purposes, so costs and services will vary tremendously based on your project. Below, we describe the average cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

Typically, London homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. How much it will cost is based on several factors, like material, size, type, the location of your home, number of windows and more.

Whether or not you want energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $299 a year on your energy bills in London.

Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

There are generally two kinds of window installation services: full-frame and pocket installations.

Full-frame installations entail replacing the complete window, including the trim, sill and frame. Full-frame installations are necessary when you want a new style or your window has considerable damage. Because full-frame installations are more involved, they will increase the overall cost. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.

If you're still debating which type of installation to get, you can ask your installer and get their advice. The decision mostly is influenced by the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in London

In our search to find the most reliable, eco-friendly window installers in London, EcoWatch evaluated dozens of companies before landing on these. Along with energy efficiency, we assessed window companies all across the state and assigned rankings using the following methodology:

Service Area

Because this is a guide for London, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in London.

Work Quality

We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company included on this list to make sure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including professionalism, quality of installation, warranty, quality of parts, cost and more.

Cost

This one is a give-and-take: similar to most services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a sizable investment, so you'll want to be certain that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to London's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of London window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
