How much should I budget for security window film in Welwyn Garden City?
Guide prices for security window film in Welwyn Garden City are £54 to £132 including VAT (£45 to £110 plus VAT) per m² for supply and fitting. We confirm a fixed price in writing after a free survey, before any glass is ordered.
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.

What to think about first
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.
Is the glass suitable
Some double-glazed units and coated or tinted glass can suffer heat stress with certain films. We check the glass and the unit maker's guidance first.
Consents and safety: England
Safety glass in critical locations
In England, section 5 of Approved Document K treats glazing in doors and in side panels within 300 mm of a door edge, from floor level up to 1,500 mm, and any other glazing below 800 mm, as a critical location. Glass there should break safely, be robust, or be guarded. Laminated or toughened glass meeting BS EN 12600 class 3 is the usual answer, rising to class 2 for door and side-panel panes wider than 900 mm.
Listed buildings and conservation areas
In England, listed building consent from the council may be needed to replace historic glass such as crown or cylinder glass, or to alter glazing bars, sashes and frames. Historic England publishes guidance on traditional windows. Secondary glazing and window film are often easier to agree because they can be removed later, but the council's conservation officer makes the decision.

Security window film in Welwyn Garden City: questions
Do you cover Hatfield as well as Welwyn Garden City?
Yes. As well as Welwyn Garden City, we can arrange surveys in nearby Hatfield, Hertford and St Albans. Dates depend on installer availability.
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.
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.
