There is nothing worse than moving into a new rental flat and realising the bedroom has no curtains. Or worse, the landlord has installed thin, see through vertical slats that let the streetlights in at 2 AM, turning your bedroom into a disco.
You can’t drill holes for a curtain pole. You can’t screw a roller blind into the lintel.
So, you tape a bin bag to the window. It works, but it looks like a crime scene.
The solution? No Drill Overlay Blinds.
There are three types of “Overlay Blinds” that require zero screws and leave zero marks:
- Clamp (Klemmfix): Clips onto the uPVC frame of opening windows (Premium).
- Adhesive Paper: Instant, cheap, cut-to-size (Budget).
- Fabric & Fasteners: Heavy-duty blackout fabric that attaches via removable strips (Total Blackout).
We tested the market leaders from the viral “Maritown” paper shades to the heavy duty “Grandekor” rollers to see which ones stay up in a humid room, which ones block 100% of light, and which ones look like real furniture rather than a temporary fix.

The “Open Window” Flowchart
- Box 1: Does your window open inwards/outwards?
- Arrow YES: -> Buy Grandekor (Clamp).
- Arrow NO (Fixed Glass): -> Buy Maritown or easynight (Adhesive).
Before you buy the premium options, you must check your window type.
- The Clamp Problem: The Grandekor relies on hooks that go over the top of the window sash. If your window is a fixed pane of glass that doesn’t open, or a wooden sliding sash window, the hooks have nowhere to grip. You must use the adhesive options.
1. Top Pick: Grandekor “Klemmfix” Roller Blind
If you want a blind that looks like it was professionally installed by a carpenter, get the Grandekor. It uses a clever German system called “Klemmfix” (Clamp Fix).
Why It’s Renter Friendly
- The Clamp System: It comes with two adjustable plastic hooks. You open your window, hook them over the top of the white uPVC frame, and tighten them with a small screw (that pushes against the clamp, not the window). The blind roller then clicks into these hooks.
- Zero Damage: The hooks have rubber pads so they don’t scratch the plastic frame. When you move out, you unhook them, and the window is pristine.
The “Chain Safety” Note
It comes with a standard beaded chain. Be careful to use the included “Safety Clip” to pin the chain to the frame (using sticky tape) if you have pets or children, as dangling chains are a strangulation risk.
Pros:
- Looks exactly like a permanently installed roller blind.
- Available in “Daylight” (Privacy) or “Blackout” fabrics.
- Sturdy enough to last years.
Cons:
- Only works on opening windows.
- The blind mechanism protrudes into the room by about 5cm.
2. The Budget Pick: Maritown Stick-On Pleated Blind
If you just need to cover a bathroom window or a hallway pane today for under £15, this is the solution. It is essentially a high quality, thick paper fan with industrial 3M tape on the top.
Why It’s Renter Friendly
- Cut to Size: It fits any window width. You measure the width of your glass, put the blind on a chopping board, and saw through the rolled up paper with a sharp kitchen knife.
- The Price: At roughly £10-£12, it is the cheapest way to get privacy instantly. It is Amazon’s Choice for a reason. It solves the problem immediately.
Pros:
- Instant installation (Peel and Stick).
- Fits awkward/non-standard window sizes.
- Surprisingly effective blackout capability.
Cons:
Operation: To “open” it, you have to use the included plastic clips (like clothes pegs) to hold it up. It doesn’t roll up on a mechanism.
It’s Paper: It creases easily. It won’t last forever.
3. The “Cinema” Pick: easynight Portable Blackout
Originally designed for travel, the easynight is the heavy-duty option for people who need 100% darkness (e.g., Night Shift workers or Projector owners).
Unlike the paper blinds, this is a high quality fabric sheet that creates a total seal against the light.
Why It’s Renter Friendly
- The Attachment System: It doesn’t use suction cups (which often fall off at night). It uses removable self-adhesive fastening strips (similar to heavy duty Command strips). You stick the white pads to your uPVC window frame and the fabric attaches firmly to them.
- Removal: When you move out, the adhesive pads can be peeled off the frame without leaving residue (warm them with a hairdryer first to be safe).
Pros:
- Total Blackout: Because it attaches to the frame, it eliminates the “halo” of light around the edges.
- Silver Backing: Reflects heat in summer to keep the room cool.
- Cut to Size: You get a massive sheet and cut it to fit your exact window shape perfectly.
Cons:
- Setup Time: You have to measure, cut the fabric, and stick the pads individually. It takes about 15 minutes.
- Operation: You can’t just “pull a cord” to open it. You have to physically pull the fabric off the pads to let light in.
Annotated Manual: The “Kitchen Knife” Hack
The Maritown Paper Blind says “Cut to Size,” but people mess this up by unrolling it first and trying to cut a 2-metre long sheet with scissors. It ends up jagged.
Here is the clean way to do it.
Step 1: Measure the Glass
Measure the width of your window pane (glass only, not the frame).
Step 2: Mark the Roll
Keep the blind tightly rolled up and secured with the included clips. Measure from the edge and mark your cut line with a pencil on the roll itself.
Step 3: The Sawing Motion
Place the roll on a sturdy chopping board. Use a sharp serrated bread knife.
- Technique: Do not push down (crushing the paper). Use a sawing motion. Saw all the way through the roll like a loaf of bread.
- Result: When you unroll it, you have a perfectly straight, factory-finish edge.
Real-World Reality: Community Feedback
We checked the reviews to see why these fall down.
1. “The Heat Crash”
User Report: “The stick-on blind fell down in the middle of the summer heatwave. The glue melted.”
💡 The Smart Tenant Fix:
Adhesive softens in heat.
Our Advice: If you stick the paper blind directly to the Glass, the sun heats the glue rapidly. Always stick the adhesive strip to the white uPVC Frame (the plastic bit) at the top. It stays cooler and holds the bond longer.
2. “The Residue Nightmare”
User Report: “I took the paper blind down and it left a line of sticky gunk that won’t come off.”
💡 The Smart Tenant Fix:
This happens with cheaper tapes left up for years.
Our Advice: Do not scrape it! Use WD-40. Spray a tiny amount on a paper towel and rub the sticky residue. The oil breaks down the glue instantly. Then wipe with soapy water. It will look like new.
Frequently Asked Questions
Do the Grandekor clamps damage the rubber window seal?
No. The clamps are made of thin metal or strong plastic. They sit over the rubber weather seal of the window. When you close the window, the rubber compresses around the clamp. It might leave a small indentation in the rubber for a few hours after removal, but it bounces back. It does not compromise the weatherproofing or security of the window.
Can I open the window with the blind attached?
Grandekor (Clamp): Yes. Because the blind is clipped to the opening sash itself, the blind moves with the window when you open it.
Maritown/easynight (Stick-on): Yes, but be careful. If you stick it to the fixed frame, the blind might block the handle. If you stick it to the opening sash, it moves with the window.
Do paper blinds get soggy with condensation?
They can. If your windows suffer from heavy condensation in winter, the bottom of the paper blind can absorb the water and get stained or mushy.
The Fix: Pull the blind up slightly (using the clips) before you go to sleep to leave a 2cm gap at the bottom for airflow. Or, use the easynight fabric blind which is water-resistant.
How do I clean the paper blinds?
You can’t wash them. They are non-woven fabric/paper. Use a feather duster or the upholstery attachment on your vacuum cleaner (on low power) to remove dust. If they get stained (e.g., fly spots or coffee), it is usually cheaper to replace them than to try and clean them.
Verdict: Which Blind for Your Window?
- Best for Long-Term: Grandekor No Drill Roller. If you plan to stay in the flat for 12 months+ and have opening windows, this is the only one that looks and feels like a “real” home fixture.
- Best for Quick Fixes: Maritown Stick-On Blind. If you just moved in and need privacy today for £10.99, this is the unbeatable budget king.
- Best for Sleep: easynight Blackout. It takes a bit more effort to cut the fabric and stick the pads, but the light seal is perfect.
