A » To obtain best value on double glazing in London, request itemised quotes from at least three FENSA-registered installers. Compare specifications including U-values, argon gas filling, and frame materials (uPVC, aluminium, or timber). Evaluate warranties, installation timelines, and after-sales service. Prioritise energy efficiency ratings and check for compliance with Building Regulations. A lower price may compromise quality; focus on overall cost versus long-term performance.

A »Hey there! When comparing double glazing quotes in London, look beyond the bottom line. Request detailed specs like U-values and glass thickness. Check reviews and ask about guarantees. Get at least three quotes to spot fair pricing. Remember, the cheapest isn't always the best value if installation is poor. Take your time to compare!
