Install interior shutters.

Unlike off-the-shelf blinds, shutters are a permanent fixture. Precise installation is critical; even a few millimetres of misalignment can prevent the louvres from operating correctly or cause the panels to sag over time.

What Does the Work Involve?

• Initial Survey: A detailed "check-measure" of the window recess to identify if the opening is out of square (common in older UK properties).
• Surface Preparation: Removal of existing curtains, tracks, or blinds and filling of old fixing holes.
• Frame Assembly: Constructing the shutter frame (L-frame or Z-frame) on-site to ensure it matches the window's dimensions.
• Mounting: Securing the frame into the window recess or onto the architrave using specialised fixings.
• Hanging Panels: Attaching the shutter panels to the frame hinges and checking for level alignment.
• Fine-Tuning: Adjusting tension screws, aligning magnets, and ensuring the louvres rotate smoothly.
• Finishing: Applying colour-matched sealant (caulk) to close any small gaps between the shutter frame and the wall.

Typical Costs

Prices for shutters are typically calculated per square metre (m²). The following table reflects realistic 2025/26 UK prices including VAT and professional installation.

Total project costs are heavily influenced by the material chosen and the complexity of the window shape. Bespoke shapes (arches or circles) can increase the price by 50% or more compared to standard rectangular units.

Pro Tip: Most UK shutter companies offer a "Full Service" price that includes the survey, the shutters, and the installation. This is usually safer than "supply-only" as the installer takes responsibility for measurement errors.

How Long Does It Take?

• Initial Survey: 30–60 minutes per room to ensure precise measurements.
• Lead Time: 8–12 weeks for bespoke UK-made or imported shutters.
• Standard Window Install: 1–2 hours per window.
• Bay Window Install: 3–5 hours due to angle alignment.
• Whole House (8-10 windows): 1–2 full working days.

DIY or Professional?

While DIY shutter kits are available, they are high-risk. If your measurements are off by even 2mm, the shutters may not fit the recess or the panels may strike the frame, and bespoke items are non-refundable.

Professional installers have the tools to "shim" frames and plane panels to fit windows that aren't perfectly square. In the UK, there are no specific building regulations for shutters (unlike windows or electricals), but a professional installation usually comes with a 5-to-10-year structural warranty that DIY installs lack.

Choosing the Right Tradesperson

• Look for installers with specific "Window Treatment" or "Joinery" experience.
• Check for membership in trade bodies like the British Blind and Shutter Association (BBSA).
• Avoid companies that pressure-sell during the initial survey or refuse to provide physical material samples.

• "Do you use your own fitters or sub-contractors?"
• "What is the warranty on the finish/paint against fading or peeling?"
• "Is the survey fee deducted from the final installation cost?"
• "How do you handle windows that are significantly out of square?"

UK Regulations

• Listed Buildings: If you live in a Grade I or II listed property, you may need "Listed Building Consent" if the shutters alter the external appearance of the home.
• Conservation Areas: Usually less restrictive, but it is worth checking with your local council if you plan an unusual external colour.
• Child Safety: While shutters are inherently "safe by design" as they lack cords, any integrated room-darkening blinds must comply with BS EN 13120 standards.

Common Problems

• Handle Obstruction: If the frame depth isn't calculated correctly, the shutter louvres may hit the window handle when tilted.
• Light Bleed: Expecting 100% blackout; shutters will always have minor light filtration unless paired with an integrated honeycomb blind.
• MDF in Damp Areas: Installing standard MDF shutters in bathrooms often leads to swelling and "blown" joints within 12 months.
• Sagging Panels: Occurs when large panels are made from heavy MDF without sufficient hinge support.
