Triple glazing costs around 30-50% more than double glazing and provides a modest improvement in thermal performance — typically reducing heat loss by a further 20-30%. For most UK homes, A-rated double glazing is the best value option. Triple glazing makes most sense if you live in an exposed or particularly noisy location, or if you are building a passive house to very high energy standards.

Look for FENSA or CERTASS registration, which confirms they can self-certify building regulations compliance. Membership of the Glass and Glazing Federation (GGF) is an additional quality mark. Check that they carry public liability insurance of at least £2 million and ask for references from recent local installations. Avoid any fitter who cannot provide a registered scheme number.

UPVC is the most popular and affordable option — low maintenance, good insulation, and widely available. Aluminium frames are slimmer, stronger, and suit modern designs, but cost 40-60% more than UPVC. Timber frames offer a traditional look and excellent insulation but require regular painting or staining every 3 to 5 years. Each material has its strengths depending on your property style and budget.

Yes, a dropped or misaligned window is one of the most common repairs window fitters deal with. The fix usually involves adjusting the hinges, replacing a broken gearbox mechanism, or realigning the sash within the frame. Most repairs take under an hour and cost between £60 and £150. Left unfixed, a window that won't close properly is a security risk and wastes energy.

Yes, using a FENSA-registered fitter in UK is strongly recommended. It means your installation automatically complies with building regulations and you receive a certificate without needing a separate council inspection. If you use a non-FENSA fitter, you must arrange a building control inspection yourself, which costs £200 to £400 and can delay completion.

Yes, replacing old single glazing or failed double glazing with modern sealed units will noticeably reduce outside noise. Standard double glazing reduces noise by around 25-30 decibels. For maximum noise reduction, ask about acoustic glass or unequal pane thickness (e.g. 6mm outer, 4mm inner) which disrupts sound vibrations more effectively. Triple glazing also offers improved sound insulation.
