Fit new blinds.

For UK homeowners, hiring a professional installer guarantees that all window treatments comply with mandatory child safety regulations. This guide outlines what to expect regarding costs, timelines, and the technical requirements for a high-quality installation in 2025.

What Does the Work Involve?

• Site Survey: Taking "recess" or "exact" measurements to ensure the blinds fit perfectly within or over the window frame.
• Substrate Check: Identifying the wall or lintel material (brick, plasterboard, or uPVC) to select the correct fixings.
• Bracket Installation: Levelled mounting of top, side, or face-fix brackets using professional-grade drills.
• Blind Mounting: Securing the blind into the brackets and testing the tension and tracking.
• Child Safety Compliance: Installing mandatory cord tidies, cleats, or break-away connectors to meet UK legal standards.
• Final Calibration: Adjusting limit stops on motorised blinds or ensuring slats tilt evenly on Venetians.

Typical Costs

Prices vary significantly based on whether you are paying for "fitting only" or a "supply and fit" service. Labour rates are typically higher in London and the South East.

Costs are influenced by the number of windows, the height of the installation (e.g., skylights or conservatories), and the complexity of the window shape, such as bays or arches.

How Long Does It Take?

• Single Standard Window: 20–40 minutes for a basic roller or vertical blind.
• Bay Window: 1.5–3 hours depending on the number of segments and angles.
• Whole House (3-bed semi): 4–6 hours for standard blinds throughout.
• Plantation Shutters: 2–4 hours per window due to frame assembly and levelling.

DIY or Professional?

While DIY fitting is possible for simple roller blinds, professional installation is recommended for heavy wooden blinds, motorised systems, or bay windows. Professionals have the heavy-duty SDS drills required for concrete lintels, which often defeat domestic DIY drills.

UK Law (BS EN 13120) requires all internal blinds to be fitted with specific safety devices. A professional installer ensures your home is compliant and safe for children and pets.

Choosing the Right Tradesperson

• Check Memberships: Look for members of the British Blind and Shutter Association (BBSA).
• Insurance: Ensure they have Public Liability insurance in case of accidental damage to your window frames or walls.
• Portfolio: Ask to see photos of previous bay window or conservatory installations.
• Questions to Ask:
  • Are the safety cleats included in the quote?
  • What happens if the blind doesn't fit the recess perfectly?
  • Do you offer a guarantee on the installation labour as well as the product?

UK Regulations

• Child Safety (BS EN 13120): It is illegal for trade installers to fit blinds that do not meet cord and chain safety requirements.
• Part L Building Regs: Certain thermal blinds can contribute to your home's energy efficiency rating by reducing heat loss through glazing.
• WEEE Regulations: If installing motorised blinds, the installer should advise on the disposal of old electronic components or batteries.

Common Problems

• Incorrect Measurements: Forgetting to account for window handles or tiles within the recess, resulting in a blind that won't lower.
• Blown Plaster: Using the wrong drill bit or speed on old UK plasterwork can cause significant surface damage.
• Hitting the Lintel: Striking a steel or concrete lintel without the correct equipment often leads to wonky, insecure brackets.
• Uneven Hanging: Failure to use a spirit level on the brackets, causing the fabric to "telescope" or fray against the side of the mechanism.
