Wall panel installation

For most UK homeowners, the appeal lies in the lack of grout lines and the ability to cover uneven or damaged plaster without extensive remedial work. However, achieving a professional, watertight finish requires precision cutting and the correct choice of adhesives to ensure the panels remain secure for years to come.

What Does the Work Involve?

• Site Survey: Measuring the area accurately and checking walls for moisture or significant structural defects.
• Substrate Preparation: Removing old tiles (if necessary), degreasing surfaces, and ensuring the wall is flat enough for the specific panel type.
• Dry Fitting: Cutting panels to size using a fine-tooth saw or circular saw and dry-fitting them to check for gaps around windows, sockets, or pipes.
• Adhesive Application: Applying high-grab specialist adhesive to the back of the panels or directly to the wall in the manufacturer-specified pattern.
• Fixing & Leveling: Pressing panels into place and using a spirit level to ensure they are perfectly plumb before the adhesive sets.
• Trimming & Sealing: Installing internal/external corner trims and end caps, then applying sanitary-grade silicone to all joints to ensure a 100% waterproof seal in wet areas.
• Final Commissioning: Re-fixing faceplates for sockets or plumbing fixtures and cleaning away excess sealant.

Typical Costs

The cost of wall panel installation varies significantly based on the material chosen—PVC panels are the most budget-friendly, while high-pressure laminate (HPL) or stone-resin composites sit at the premium end of the market.

Total project costs are heavily influenced by the condition of the existing walls. If a builder needs to "dot and dab" plasterboard or install a timber batten frame to level out a wonky wall, labour costs will increase by at least one full working day.

How Long Does It Take?

• Single Feature Wall: 3–5 hours including prep and trimming.
• Standard Bathroom (Wet Area Only): 4–7 hours depending on the number of pipe cuts required.
• Full Room Enclosure: 1–2 days, allowing for adhesive curing and intricate corner work.
• Decorative Hallway Panelling: 1–2 days, as this often requires priming and painting after installation.

DIY or Professional?

While basic PVC tongue-and-groove panels are accessible for a confident DIYer, high-end laminate panels are expensive and unforgiving; a single wrong cut can be a £150 mistake. In bathrooms, a professional installation is highly recommended to ensure the integrity of the waterproof seal. If your project involves moving radiators or electrical sockets, you must ensure the work complies with Part P (Electrical Safety) and that any gas work is handled by a Gas Safe registered engineer.

Professional installers carry the right tools, such as track saws and suction lifters, which are essential for handling large-format panels without cracking or chipping the decorative surface.

Choosing the Right Tradesperson

• Look for builders or specialist bathroom fitters with experience in specific brands (e.g., Fibo-certified installers).
• Check for "Public Liability Insurance" to cover any accidental damage during the install.
• Red Flag: Any builder who suggests "dotting" adhesive on the corners only—this leads to panels bowing and seals failing.
• Question: "How do you treat the bottom edge of the panel where it meets the shower tray or bath?" (The answer should involve a specific sealant tool or a 'bottom profile' trim).
• Question: "Do you use solvent-based or solvent-free adhesive?" (Solvent-based can melt some PVC panel cores).
• Question: "Is waste removal included in your quote, or will I need to arrange a skip?"

UK Regulations

• Building Regulations Part B: Panels used in kitchens or near heat sources must meet specific fire-spread ratings (usually Class 1 or Class 0).
• Building Regulations Part G: Waterproofing in "wet rooms" must be sufficient to prevent moisture damage to the structure of the property.
• Part P: Any electrical alterations (moving switches/sockets onto the new panels) must be certified by a competent person.
• Paperwork: You should receive a written invoice and, ideally, a 12-month workmanship guarantee alongside the manufacturer’s product warranty.

Common Problems

• Blown Panels: Caused by using the wrong adhesive or failing to degrease old tiles before sticking panels over them.
• Leaking Joints: Often the result of "skimping" on silicone inside the corner trims or failing to use a sealant expansion gap at the base.
• Pattern Misalignment: Occurs when the installer doesn't check that the panels are perfectly level from the first board, causing a "run-off" effect across the room.
• Thermal Expansion: PVC panels expand and contract; if they are fitted too tightly against ceilings or floors without a small gap, they can buckle in the summer.

Frequently Asked Questions

Can wall panels be installed over existing tiles?

Yes, as long as the tiles are firmly adhered to the wall. The surface must be thoroughly cleaned with a degreasing agent to ensure the adhesive bonds correctly.

Are wall panels better than tiles?

Panels are generally faster to install and easier to clean because there is no grout to go mouldy. However, tiles offer more design variety and are often preferred in period properties for a traditional look.

How do I clean wall panels without damaging them?

Use warm soapy water and a soft cloth. Avoid abrasive cleaners, bleach, or scouring pads, as these can scratch the protective laminate or PVC coating.

Can I hang heavy items like mirrors or cabinets on the panels?

You cannot hang heavy items from the panels themselves. You must drill through the panel into the masonry or studwork behind and use appropriate wall plugs or fixings.

Are wall panels fireproof?

Most quality panels are fire-rated, but the level of resistance varies. Always check the manufacturer's technical data sheet if installing near a hob or in a commercial setting.
