So, if you are thinking about how much it will cost for new or replacement windows, looking for good installers to do the work and need a bit of help to decide on which design suits your home best, then our double glazing prices guide for 2019 is the answer. You need to take into account quite a few things, as different scenarios will result in different prices.

For example:

  • If all the windows you want to replace are on the ground floor, it is likely to cost less than if they are on an upper floor where the installer may need to put up some scaffolding.
  • Sash windows will cost more than casement windows.
  • Hardwood or aluminium windows will cost more than uPVC Windows.
  • “A++rated” double glazed units cost more than “B rated” units.
  • Coloured Aluminium or UPVC windows are costlier than white versions.
  • Argon gas filled sealed units are costlier than standard “air filled” sealed units.

So, the best way to get an accurate double glazed windows cost is to have your property measured-up by a professional and have a written quotation based on that survey. Get as many different quotations as you like, we suggest at least 4, and then compare them to see which represents the best deal – then ask for a better deal!

The cost of buying a single small uPVC double glazed window can be as low as £150 or around £300 to £400 for an average sized unit, but that price per window will drop if you are ordering multiple units at the same time.

To be more specific, a C-rated 1200mm x 1200mm white uPVC casement window can cost as little as £154 for just the unit itself. The majority of the rest of the cost is going to be for the labour involved in fitting the window.

  • Sash Windows: Average prices fitted £500 to £700. Sliding vertically to open or close, the sash window design is often seen in older Victorian or Edwardian style properties. A complex design that is reflected in the price. Modern UPVC sash windows are less costly than timber versions. READ MORE
  • French Windows: Average prices fitted £300 to £400. Basically the French window design (not a French patio door) is 2 side hung casements fitted side by side, in the same outer frame. They open outwards from the centre. READ MORE
  • Tilt & Turn Windows: Average prices fitted £400 to £550. Another version of the casement style, but the opening section will also tilt backwards into the room to allow for ventilation. Usually fitted so that the main window section will open inwards. Another quite complex design, hence the higher cost. READ MORE
  • Bow Windows & Bay Windows: Average prices fitted £400 to £550. Bow and Bay designs are “picture windows” and as such are usually quite large. They are also complex to install. A bow window is one that has a series of units fitted in such a way that the whole window curves outwards from the house. A bay is one that is a 3-sided unit that also projects forward from the house. READ MORE

In Summary:

Top 10 things to remember about getting cheap double glazing prices & Quotes in 2019

  1. The more you personalise your new windows, the more they are likely to cost.
  2. Only have opening section where you really need them – openers cost more than fixed panes.
  3. If you like white frames, fit white frames. Colour is nice, but can add up to 10% to the cost of the frames (so do wood-grain finishes).
  4. A++ rated double glazed windows are the most efficient, but also priciest.
  5. 28mm sealed units are super-efficient, but 24mm is considered optimal.
  6. Argon gas filled units and low-e glazing will push the price up.
  7. Always get several quotes in writing from a range of different suppliers & installers
  8. Make sure the installer you deal with is registered with a recognised Trade body like GGF / FENSA / CERTAS / DGCOS.
  9. Double check the guarantees and warranties.
  10. Always negotiate on the first price you are given – if you don’t ask, you don’t get!

Should You really pay out extra for super energy efficient double glazed windows?

This is a thorny question, as we all should be more considerate about energy saving both in terms of the planet and our pockets.

However, it would seem from statistics (see link below), that upgrading to C-rated windows (from single glazing) will save about £70 per year on your energy bill and going up to A+ rated windows can only lift that to £80 per year.

So, in this instance, we will leave it up to you to judge what is best for your home (and pocket).
