At WindowTreat, the advice you receive is as important as the film we install. Exact pricing depends on your glazing and performance requirements. Without the right advice, it is easy to choose a film that looks impressive on a datasheet but delivers almost no benefit once installed.
Window Film Pricing Overview (UK 2026)
Typical installed costs on vertical glazing (not roof glazing):
- Internal films: £45–£90 per m²
- External films: £90–£160 per m²
- Premium spectrally selective external films: £130–£190+ per m²
- Premium insulation window films: £190-300 per m²
For a typical 6 metre set of bi-fold doors:
- £1,000 → £3,000+ depending on film type
Why Prices Vary So Much
Modern double glazing changes how window film performs.
Internal films can lose a significant amount of their real-world performance on modern glass.
This is why:
- Two films can have similar specifications
- But deliver very different results
Choosing the right type of film matters as much as the price
