Hello,
Many thanks for your email,
Our wooden venetian blinds are not available with a no drill system unfortunately,
The only no drill option in a wooden venetian style is the perfect fit wooden venetian blinds where the bracket is pushed into the beading of your window- please see link to product below,https://www.blindsbypost.co.uk/perfect-fit-blinds/perfect-fit-venetian-blinds
You would though need to check if you widow is compatible and have enough clearance per the measuring guide though first- https://www.blindsbypost.co.uk/measuring-guides#perfect-fit-blind
