When it comes to window replacement, there are a few different considerations that should be made. You need to do a cost analysis, including everything from the material of the frame to the specifics of the glass itself. The price of made-to-measure windows, which are made to bespoke measurements, is going to be higher than the price of off-the-shelf ones. Adding the cost of installation and maintenance to your total is something else that needs to be accounted for. So how much does it cost to have double windows installed? Is it really worth it in the end?
Purchasing double-paned windows is an excellent method to increase the energy efficiency of your home and save money on your monthly energy bills. When considering the various forms of glazing, keep in mind that windows play an important role in preventing heat from escaping via the structure of the building. According to the information that can be found on energy.gov (opens in a new tab), heat gain and loss through a home’s windows is responsible for anywhere between 25 and 30 percent of a home’s total heating and cooling energy use. Therefore, you stand to save a respectable amount of money if you make sure that the glazing in your home is efficient. When you are conducting the calculations to determine how much it will cost to double-glaze a window, keep this in mind.

According to Matt Higgs, director at Kloeber, “Upgrading from single to double glazing might save several hundred pounds a year in a modest-sized house.” [Citation needed] (opens in new tab). As time goes on, the return on this investment will increase as a direct result of the persistent upward trend in the cost of energy.
As an illustration, the cost of installing double glazing in a house with three bedrooms might be somewhere in the neighbourhood of ten thousand pounds at the low end. When there are so many different factors to take into consideration, however, it is impossible to determine an approximate price. Bringing your specifications up to a premium level by using a premium frame material, such as oak, and applying a special coating to the glass may bring the total cost closer to £50,000.
How much does it cost to get double glazed windows made of UPVC?
UPVC requires little to no maintenance, is extremely secure, and can be purchased in a diverse range of colours and finishes. Over the course of the past three decades, there has been a tremendous rise in the quality of UPVC windows. If your budget won’t stretch to more quality materials like timber or metal, the most cost-effective choice is to install double-paned windows with plastic frames. On a per-square-meter basis, the normal beginning price is around around £500.
How much does it cost to have double glazing installed using uPVC?
The cost of each style of window can range anywhere from £500 to £1,230, as stated by Everest (link opens in new tab), which reports that the typical price for a type of casement window can be anywhere between the two amounts. The most cost-effective choice would be windows with casement sashes. Sash windows are the next option, and their price will be approximately fifty percent higher than that of regular casements. In most cases, the price of installing a bay window will be at least twice as much as that of installing a casement window. Once more, this is something that is entirely dependant on the other components of your specification.
Costs associated with installation – Checkatrade estimates that a competent window fitter will charge between £25 and £35 per day for their services. On the other hand, it is possible that these rates are far higher in London and the South East. On the bright side, UPVC windows are likely the solution that is used the most frequently across the country. This indicates that it shouldn’t be too difficult to locate a qualified specialist who possesses the necessary abilities and knowledge to install your new windows. According to Steve Rawding, sales and marketing director at SEH BAC, “Installation prices are typically identical, independent of the frame material you’re utilising.” [Citation needed] (opens in new tab). “The pricing of the products will differ based on the frame material that you choose to use,” the salesperson explained.
Costs associated with maintenance – Other than the routine cleaning and lubrication of the hinges, UPVC windows require almost little maintenance. The fact that this style of double-glazed window requires very little maintenance is an undeniable advantage of going with this particular option. It is very suggested that any moving parts be oiled and greased on an annual basis. According to Neal Harper, the managing director at Wolverhampton Glass, “This will maintain the life of the products much beyond their guarantees.”
How much does it cost to get double glazing made out of wood?
There aren’t many materials that can compete with the warmth and charm of wood. This solution works well in both contemporary and more classic settings. For homes located in historic districts or conservation areas, the use of timber may be mandated by the local planning authority. Wood also has a wide range of customization options because it can be stained, painted, or lacquered to provide a variety of looks.

In addition to this, timber is a natural insulator. This suggests that the thermal performance of your double-glazed windows may improve as a result of using it. When properly maintained, the service life of timber windows is greater than sixty years.
What is the going rate for double-paned windows made of timber?
Cost for each style of window – Depending on the style of window, the cost might range from approximately £200 for a modest fixed window made of softwood to approximately £450 for an oak window that has been covered with aluminium. According to Matt Higgs from Kloeber, the price of a modest tilt and turn window can range anywhere from £375 for softwood to £1,000 for oak with aluminium cladding. This information was provided by Kloeber. “Expect to pay anywhere from £350 to £775 for a tiny opening casement window,” one customer was told.
Cost of installation – Although there shouldn’t be a significant difference in installation costs between different types of frame materials, it’s likely that the cost of installing timber windows will be more than the cost of installing UPVC windows. According to Robert Owens, the sales manager of Westbury Windows & Joinery, “Generally speaking, the cost of installation will be higher if you use timber” (opens in new tab). The labour costs associated with working with aluminium and UPVC are typically lower. Installing wooden doors and windows is a task that requires a higher level of expertise from a carpenter. You can anticipate paying approximately £3,000 for a trained and experienced installation crew for a house of a more modest size with three bedrooms.
Costs associated with maintenance – The majority of the maintenance, such as cleaning your windows and lubricating the moving parts, will be something that you will be able to handle on your own, which will reduce the overall cost of ownership. Timber, on the other hand, has a higher maintenance requirement compared to UPVC and aluminium. It will need to be repainted and/or revarnished at regular intervals over the course of several years. This is dependent on the degree to which the wood is exposed to the outdoors (which will vary across the whole house). Quote Advisor estimates that the cost of repainting the wood windows of a semi-detached house will be between £2,500 and $2,700 on average (including labour, paint and materials).
How much does it cost to get double glazed windows made of aluminium?
Aluminium windows are a great option for modern homes because they are not only current but also sleek and attractive. This particular type of metal has a high natural strength but is quite easy to work with. It indicates that slimmer frames are possible to attain. This allows the most amount of natural light to enter your home while also increasing the quantity of glass in the unit’s central core.

Additionally, depending on the overall look that you want to achieve, there is a wide variety of finishing that can be applied. The fact that aluminium is resistant to bending and corrosion is yet another one of its many benefits. In case that wasn’t enough to convince you, aluminium windows require little to no upkeep.
How much does it cost to get double glazing made of aluminium?
Cost for each style of window – According to Matt Higgs, who works for Kloeber, you should allocate around £500 (plus VAT) for an outward opening casement window. If you have a larger window, the price per square metre will drop even further. The type of glass used will, of course, have an effect on the final price, just as it does with every other kind of window. According to Steve Rawding at SEH BAC, “the typical price of a casement window is between £500 and £700, the average price of a sash window is roughly £1,000 to £1,200, and the average price of a tilt-and-turn window is between £700 and £900.”
Cost of installation – The amount you pay to install aluminium windows won’t vary by too much from what you’d pay to place UPVC or timber units in your home. However, finishing trims for this kind of metal might be more expensive and specialised than those for plastic, so the pricing may vary slightly depending on the specifics of the design. ‘If you’re replacing existing windows, then typically, installation costs will be factored into the cost of the products you’re looking for,’ says Edward Stobart, sales manager at IDSystems. ‘If you’re replacing existing doors, then typically, door installation costs will be factored into the cost of the products you’re looking for’ (opens in new tab). If you are placing windows in a new extension or self-build, it is likely more cost-effective to order windows on a supply-only basis and have your builder install them. Before placing an order, you should check that your builder is willing to perform this and that it is included in the estimate.
Costs associated with maintenance – Aluminium needs very little, if any, maintenance beyond being cleaned and oiled at the hinges and locks. The product warranty need to extend to include the resolution of any other problems that may develop with your windows.
What other costs are there associated with double glazing?
Extra costs for double glazing include:
- A dual-color finish will drive up the cost. According to Robert Owens, who works at Westbury Windows & Joinery, the business, “if you want a dual colour finish where the windows are a different colour inside and out, that’d cost more.”
- Adding features to the glass such as soundproofing or a coating that prevents solar heat gain will result in an increase in the total cost.
When determining how much it will cost to install double glazing, be sure to evaluate all of the different bids using the same criterion. You will get a more accurate picture of the whole cost with this information.
