247 Blinds' Honeycomb Perfect Fit blind combines a cellular fabric structure with a clip-in frame that requires no drilling - making it one of the more considered options for UPVC windows where thermal performance matters. It's offered in 27 colourways, with prices starting from £39.14.
Who it suits
The perfect-fit format is specifically designed for UPVC double-glazed windows with rubber gaskets. The frame clips onto the window's rubber seal without screws, which means renters and anyone reluctant to drill into UPVC frames will find this a practical route to proper window coverage. If your windows are timber or aluminium, this fitting method does not apply - standard brackets would be needed instead.
The honeycomb fabric structure makes this a reasonable choice for rooms where heat loss through the window is a real concern. The sealed air pockets between fabric layers provide insulation that flat roller or roman fabrics simply can't match. In a bedroom with an older double-glazed unit facing north, the difference in winter draughts can be noticeable. The retailer does not state an opacity level in the listed product details, so if blackout performance is a hard requirement - for a young child's room or a shift worker's bedroom - confirm with 247 Blinds before ordering rather than assuming.
Bathrooms present a potential issue: the perfect-fit frame traps the blind tight against the window, which can limit airflow and trap condensation. Check that your bathroom window ventilates adequately before fitting any sealed perfect-fit blind.
The colours
27 colours available
The six finishes sit firmly in the neutral-to-cool range: Anthracite Grey, Titanium Grey, and Void Black for darker rooms or modern interiors; True Cream, Cotton White, and Light Taupe for rooms that need a lighter touch. There are no warm earth tones, patterned options, or statement colours - this is a range built for unobtrusive utility.
Anthracite Grey and Titanium Grey are close neighbours in tone; if you're deciding between them, request samples, as on-screen colour rendering varies. The Light Taupe is the warmest of the six and sits between the two greys and the white options in terms of room feel.

Starting below £40, this range sits at an accessible entry point for a cellular perfect-fit blind. The honeycomb construction and no-drill frame typically attract a premium over a plain roller in the same fitting format, so the from-price reflects reasonable value for what the fabric offers. As with all made-to-measure blinds, the final price rises with width and drop - the price grid above shows how the cost scales for your specific window size.
How it compares
Against a standard perfect-fit roller blind, the honeycomb fabric adds meaningful insulation; if your main goal is simply covering a window without drilling, a plain perfect-fit roller will cost less. Against a conventional honeycomb blind fitted with standard brackets, the perfect-fit format trades some size flexibility (it's constrained to windows with the right rubber gasket profile) for a much cleaner installation.
If privacy and opacity are the priority rather than insulation, a blackout perfect-fit roller may be a more direct fit. If you want the thermal benefits of cellular fabric on a non-UPVC window, a honeycomb blind with standard top-fix brackets gives the same fabric performance without the fitting constraint.
Fitting and operation
Perfect-fit frames clip into the rubber gasket channel around UPVC window panes without any wall or frame fixings. Installation is typically straightforward for a single pane, but verify that your specific window profile has the gasket depth required - some older or non-standard UPVC units don't accommodate the clip-in mechanism cleanly. The blind operates within the frame, so the fabric travels a short distance relative to the window size; measure your recess carefully to ensure the frame dimensions match your glazing unit rather than the surrounding frame.
