What should security window film cost in Caernarfon?
Our guide range for security window film in Caernarfon is £54 to £132 including VAT (£45 to £110 plus VAT) per m², including fitting. The survey is free for new installations and your fixed price follows in writing.
Security window film is a clear, tough polyester film bonded to the inside face of existing glass with a strong adhesive. When the glass breaks, the film holds the fragments together, which reduces injury from flying glass and slows down anyone trying to get through, without replacing the glass itself.
Glass and fitting options
- Thermal-stress check on sealed units and coated glass
- Blocks most UV light to slow fading
- Frosted and privacy versions for meeting rooms and bathrooms
- Removable later without harming the glass
- Edge-retention anchoring into the frame for blast mitigation
- Security films of 200 microns and thicker

Before the glass is ordered
Safety or security film
Thinner films improve how glass breaks; thicker films add resistance to attack. We match the film to what you want it to do.
Daylight application or anchored
A film applied to the visible glass is quickest. Anchoring it to the frame holds the whole pane in place and is the choice for blast mitigation.
Glazing rules in Wales
Listed buildings and conservation areas
Listed buildings in Wales need listed building consent from the local planning authority for works that affect their character, which can include replacing historic glass, glazing bars or sashes. Cadw advises on the historic environment in Wales. Reversible options such as secondary glazing are often easier to agree, but the council decides.
Replacing glass in an existing frame
Welsh Government guidance says building regulations have applied to replacement glazing since 1 April 2002, which covers replacing windows and doors. Swapping only the glass or a sealed unit in an existing frame is generally treated as a repair. New glass in a critical location should still be safety glass, and the council's building control team can confirm anything unclear.

Security window film in Caernarfon: questions
Can you survey in Caernarfon and nearby towns?
Yes. Surveys in Caernarfon, Bangor and Pwllheli are booked around installer availability.
Can film go on double glazing?
Often, but not always. Some units and coated glass can crack from heat build-up with certain films, so we check the glass type and the unit maker's guidance before fitting.
How long does window film last?
Fitted on the inside, quality films typically last many years. Life depends on sun exposure and cleaning, and we give the manufacturer's expected life with the quote.
Can film be used on listed buildings?
Film is fitted inside and can be removed, so it is often an acceptable way to protect historic glass. Check with the council's conservation officer for listed buildings.
