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 2018 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!

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.

  • 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.

In Summary:

Top 10 things to remember about getting cheap double glazing prices & Quotes in 2018

  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!

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