Upgrade your home with high-efficiency double and triple glazed windows and doors designed to improve comfort and reduce heat loss. Compliant Retrofits installs high-performance glazing solutions across Manchester to enhance energy efficiency, security and year-round insulation.
Windows and doors can be responsible for up to 20–30% of heat loss in a typical home. High efficiency double or triple glazing, combined with insulated doors, reduces heat loss, lowers energy bills, improves security and cuts noise.
A-rated double glazing (typical U-value 1.2–1.4) reduces heat loss by around 50–70% compared to single glazing, and insulated composite doors (typical U-value 0.8–1.2) perform even better than standard UPVC — typically saving around £100–£200 per year on heating, depending on your property and usage.
Double and triple glazing significantly reduces external noise — traffic, neighbours, aircraft, trains. Acoustic glazing (laminated glass) offers even better noise reduction, and insulated doors also cut sound transmission.
Modern double glazing with multi-point locking and composite doors are far more secure than single glazing and old wooden doors. Toughened or laminated glass is harder to break; composite doors have steel or timber cores.
High efficiency windows and insulated doors with warm edge spacers and argon gas fill reduce condensation on internal glass surfaces and door panels.
New windows and doors improve kerb appeal and energy efficiency, making your home more attractive to buyers.
The most popular choice for Manchester homes. Hinged, opening outward or inward, in white, woodgrain or coloured finishes — suits traditional and modern properties.
Windows sit flush with the frame when closed — traditional appearance with modern performance. Best for conservation areas and period properties.
European-style windows that tilt open at the top or turn to open fully — best for modern homes, flats and apartments.
Traditional sliding sash windows with modern double glazing — best for Victorian and Edwardian properties and conservation areas.

Conservation of fuel and power: replacement windows and doors must meet current minimum U-value requirements (1.4 W/m²K). A-rated products exceed this comfortably.
Security: doors and ground-floor windows must meet security requirements (PAS 24 or equivalent). The composite doors and upgraded windows we install meet PAS 24.
Replacement glazing must be certified for Building Regulations compliance. There are two routes: self-certification through a FENSA or CERTASS registered installer, or approval via building control. Your installation is certified through the appropriate route, and you receive the certificate for your records.
Most UPVC windows and doors do not need planning permission. Listed buildings and conservation areas require consent — we advise on your specific property.

Yes — modern double glazing with warm edge spacers and insulated doors reduce condensation significantly. However, excessive condensation may indicate poor ventilation, and we can advise on that too.
