What to know before getting a window quote online

window_quote_details

It’s important to know that getting a single window quote online doesn’t suffice to make the best decision. For the best picture of window replacement costs, you’ll need a wide range of quotes to accurately assess the price ranges available to you. These quoted prices can contain a whole host of conditions and coverages that are important to consider. 

Here are some of the main things to look out for:

  • Glazing type: UK Building Regulations demand homes to have double or secondary glazing at the very least to meet domestic energy expectations, of which both options come with their price ranges. Double glazed windows prices are the most reliable, as this is the standard demanded by regulations. In addition, the cost of triple glazing may be higher in the short term, but it can bring increased energy efficiency, resulting in significant savings on annual energy bills.  
  • Window style: There is a whole range of window styles to choose from on the market, suited for all types of aesthetics and budgets. You can choose from the simpler casement or tilt and turn windows, to more complex and elegant bay or bow windows.
  • Frame material: The main window material options on the market are timber windows, aluminium windows, UPVC or composite windows, each of which comes with its pros and cons, as well as price ranges to consider. For example, the cost of UPVC windows is much cheaper than aluminium or timber. In addition, some may opt for less common materials such as steel windows, which are much more expensive to obtain and install. 
  • Installation: The conditions of your home and window replacement job can have an effect on the final quote price you are offered. Homes with complex window replacements or outdated repairs can expect a more expensive quote than simpler window replacements.

In addition, it's recommended to look into whether you can qualify for any window grants in the UK, potentially providing partial or full cost coverage for your installation job. 

We recommend getting multiple quotes for double glazed windows, as well as working with a professional installer to ensure your home is professionally assessed, and an approach best suited to your needs is tailored.

What does a quote for window replacement contain? 

A quote for a window replacement project should detail all aspects of the job at hand. This includes the cost of the windows and material, the installation, and any other relevant services that may be required, such as outstanding repairs or depositing construction debris. 

A professional quote should include a total cost and a breakdown of the individual items for transparency and reliability. To give you a better idea, here’s a breakdown of some key details that should be clarified in a window replacement quote:

  • Windows: Prices should be clarified regarding the quantity and dimensions of windows, which can differ depending on your chosen window style (e.g. casement). In addition, clarifications should be made over the use of double or triple glazing, frame material, and any other additions such as coatings, screens, or extra features.  
  • Installation: A thorough quote should encapsulate the costs for the installation labour, clearly stating the number of expected hours as well as travel time and overtime. Costs relating to material removal and disposal, and outstanding repairs, will also need to be outlined for transparency. 
  • Other details: If any permits are needed from your local authorities, these details and the associated costs will need to be clarified in a quote. This includes the installation warranty provided after the handover. 

As a rule of thumb, the more detailed and thorough a quote is, the more likely it is that the company providing it is reliable and professional in its services. Transparency is a key indicator of quality workmanship and is likely to translate to a great finish. In some cases, the installer may even provide seasonal discounts, packages, or options for windows on finance
