Price examples plastic window frames
Prices are explained on the basis of 3 situations:
Repairing a single window frame
Does a window frame have difficulty closing, or is it slightly damaged? Replacing the entire window frame can be expensive and is not always necessary. You decide to have the window frame repaired. A repair is usually done in no time and will cost you around £150 to £200 if done quickly.
Replace the current window frame for a plastic one
The current wooden window frame is no longer good due to wood rot. You decide to have the wooden window frame replaced and a new plastic one installed. If you opt for a fixed window, you will spend around £1,000 to £1,500 for a window measuring 150 x 100 centimetres, depending on the finish. For a tilt/turn window, you can expect to pay an average of £250 more.
Plastic frames for French doors
You currently have a door through which little light comes in, but you would like to have French doors so that you have more light in your home. You opt for French doors with plastic window frames. The total cost of plastic window frames is at least £3,000 and increases as you choose more luxury.
Is there a subsidy for plastic window frames?
Does the government subsidise window frames? You can get a subsidy for window frames if you combine this with replacing your current glass for HR++ glass or triple glazing. You can then add the m2 of the window frames to the number of m2 of glass. There is a minimum of 8 m2 of glass and you may declare a maximum of 45 m2 of glass and frames added together for subsidy.
In addition, there are also requirements for the U-value of the glass you choose, and in the case of triple glass, installing insulating frames is even mandatory. The U-value indicates the insulating value of the glass. The lower this value, the better the insulation.
Some general requirements for the subsidy are to use a specialist for the installation, to carry out at least two insulation measures and to apply for the subsidy on time (within 12 months of implementation). The subsidy amounts as of January 2022 depend on the type of glass chosen and the U-value, and range from £23 per m2 to as much as £150 per m2.
Would you like more information on the conditions for this subsidy and an overview of all subsidy amounts? Then check out the central government website.

What affects plastic window frame costs?
There are several factors that affect the final cost of your plastic windows.
Type of project
Is window frame repair possible or should the entire frame be replaced? Is it about one window frame, all the window frames on one floor or perhaps all the window frames of your house? Do you want to replace a skylight, or a window on the ground floor? And do you want fixed glass, or perhaps a more expensive tilt/turn window? Get advice from a specialist about the possibilities to make the right choice and avoid unnecessary costs.
The glass you choose
Would you like the specialist to deliver your plastic frames including glass? Then you have a choice between different types of glass. Each type of glass has its own degree of insulation.
