Blinds By Post lists this as a single-colour perfect-fit roller blind - a no-drill solution designed to clip directly into the rubber gasket of UPVC double-glazed windows. With 19 finish available and prices from £61.80, it sits at the entry end of the perfect-fit market. The range is described as aluminium silver, though the single listed finish is categorised as grey.

Who it suits

Perfect-fit blinds are the right choice for renters or anyone reluctant to drill into UPVC frames. Because the frame grips the window's rubber seal, nothing is fixed to the wall or window reveal - it comes out without a trace. That makes this range worth considering for bedrooms, bathrooms, and kitchens in rented properties where a clean removal matters at the end of a tenancy.

The no-drill fitting also suits conservatories and newer-build properties where multiple UPVC windows need a consistent look without multiple fixing points. A grey neutral tone works well in both rooms where you want the blind to recede and rooms where the window itself is the dominant feature - conservatories and bright bathrooms being the clearest examples.

Bear in mind that perfect-fit frames only work with UPVC windows that have the correct rubber gasket profile. They do not fit wooden or aluminium-framed windows in the same way, so check your frame type before ordering. Very old UPVC installations may also have non-standard gaskets that are incompatible with standard perfect-fit frames; if in doubt, ask Blinds By Post to confirm compatibility.

The opacity class of this range is not stated in the retailer's listing. Confirm with Blinds By Post whether the fabric is light-filtering, dimout, or blackout before ordering - this distinction matters considerably for a bedroom, where light-filtering fabric lets in strong morning light, while dimout significantly reduces it and blackout blocks it almost entirely. For a kitchen or bathroom the difference is less critical, but it is still worth knowing before the blind arrives.

The finish

19 colours available

There is one finish: grey, listed under the aluminium silver name. This is a neutral, cool-toned grey that sits easily against most UPVC window frames and interior walls without clashing. The aluminium silver name suggests a metallic or reflective quality, though the precise shade is best confirmed by requesting a sample from the retailer before ordering made-to-measure.

A single neutral finish keeps the range simple but limits choice. If your room scheme calls for a warmer ivory or cream, or if you specifically want white to match white UPVC frames, you would need to look at other ranges. For a practical, clean window treatment where the blind is functional rather than decorative, this grey covers the need without the indecision that comes with a large colour selection.

Price by your dimensions

Enter your window size. We round up to the next standard size, which matches how the retailer actually quotes you.

At a from-price of £61.80, this sits at the accessible end of the made-to-measure perfect-fit market. As with all made-to-measure blinds, the final price rises with width and drop - larger windows cost more. Use the grid above to check the cost for your specific dimensions before committing.

How it compares

Against other perfect-fit roller blinds, the case for this range is simplicity: one colour, one blind type, a no-drill clip-in fit. If you need a wider colour palette - whites, creams, blackout fabrics, or printed designs - other perfect-fit ranges at Blinds By Post and elsewhere offer more choice. The trade-off is that more choice means more decisions, and if grey is already the right colour for your room, the decision is already made.

For windows that are not UPVC, a standard recess-fit or face-fit roller blind is a more reliable route. Inside-recess fitting on a standard roller gives a similarly contained look and works across wooden, aluminium, and UPVC frames alike. If you need blackout and your window is not UPVC, a standard roller with a side-channel kit will perform better than any perfect-fit alternative.

Fitting and operation

Perfect-fit frames clip into the outer rubber gasket of a UPVC window. You measure the visible glass area rather than the full frame opening, as the fit frame locates within the gasket line. The blind operates entirely within the frame and does not protrude beyond the window plane when raised or lowered - a practical advantage in tight reveals where an outward-projecting cassette would obstruct an opening handle or a conservatory door.

Because the frame has no fixings into the frame or wall, removal is reversible. This makes perfect-fit a good option for rooms where you may want to swap blinds, repaint the reveals, or restore the window to its original appearance. The frame itself should be kept dry; wipe it down with a damp cloth rather than soaking it.

Likely the same fabric, at other retailers

Aluminium Roller roller blinds are sold under the same name by more than one UK retailer, and the price scales identically across window sizes - a strong sign it is the same fabric from the same supplier:

  • Swift Direct Blinds from £8.99
  • Make My Blinds from £9.00
  • 247 Blinds from £26.79
  • Blinds By Post this page from £61.80

We match these on the shared name and an identical price curve, not an independent inspection, so treat it as likely the same fabric rather than confirmed - and check the specification and colour at each retailer before buying.
