Using wall panels to hide cables and pipes turns an eyesore into a finished feature — and with slatted acoustic wood panels, you also gain texture, warmth, and sound absorption in the same move.

TL;DR: Wooden slat wall panels are one of the cleanest ways to conceal cables, conduit, and exposed pipework in 2026. Run cables behind the panels before fitting, use a panel adhesive rated for the substrate, and leave a service gap of at least 20 mm between the original wall and the panel face. Aku Wood Panel supplies slatted acoustic panels in finishes including Natural Oak, Walnut, Smoked Oak, and Black Oak — all suitable for this application. The full process takes 2–4 hours for a standard 3 m² feature wall.

Why This Matters

Exposed cables behind a TV, visible conduit on a media wall, or copper pipes running along a living-room wall are among the most common complaints in UK home renovations in 2026. Chasing cables into plasterboard costs a plasterer a half-day and leaves you redecorating. Boxing out in MDF adds bulk and still needs painting. Slatted wood panels solve both problems: they sit 20–30 mm proud of the wall, the gap behind is deep enough for standard cable runs, and the finished result looks deliberate rather than remedial.

What You'll Need

Slatted acoustic wood wall panels (calculate m² — see panel calculator guide below)
High-tack panel adhesive, 290 ml cartridge per 2–3 panels
Caulking gun
Spirit level (1 m minimum)
Tape measure and pencil
Fine-tooth hand saw or mitre saw
Wooden battens, 25 mm × 50 mm (for batten-mount method)
Cable trunking or conduit clips (to secure cables to the original wall before panelling)
Safety glasses and dust mask for cutting
2 hours for prep, 1–2 hours for fitting on a 3 m² wall

Order a sample wooden wall panel in Natural Oak before committing to a full order — the grain and tone vary between batches and screens lie.

The Steps

Step 1: Map and Secure Every Cable

What it accomplishes: You cannot safely panel over loose cables — they must be fixed to the original wall surface before the panels go on.

Pin every cable, flex, and pipe run flat against the existing wall using conduit clips or adhesive cable trunking at 300 mm intervals. Group cables together where possible: a single 25 mm trunking channel can carry a mains cable, HDMI, and ethernet side by side. For copper or plastic pipes, check Building Regulations Part P (electrical) and confirm pipe runs are documented — photograph the wall before you cover it. Leave a note behind one of the end panels with a sketch of the cable routes. This takes 20–30 minutes and saves hours if you ever need to trace a fault.

Common mistake: Running a mains cable in contact with a hot-water pipe without thermal sleeving. Always sleeve or separate by at least 50 mm.

Step 2: Check and Prepare the Wall Surface

What it accomplishes: Panels bond to a clean, flat substrate. Any loose paint, flaking plaster, or moisture will cause adhesive failure within 6–12 months.

Sand down any raised edges, fill holes deeper than 5 mm with ready-mix filler, and wipe the surface with a damp cloth. Let it dry fully — in a typical UK interior in 2026, allow 24 hours after any wet work. If the wall is bare brick or heavily textured, a batten frame is more reliable than direct adhesion: fix 25 mm × 50 mm battens horizontally at 400 mm centres using suitable masonry fixings, then glue or pin panels to the battens. The batten method also increases the service void to 50 mm, which gives more room for thicker cable runs or pipe lagging.

Common mistake: Applying adhesive to damp plaster. The bond strength of high-tack panel glue drops by roughly 40% on a wet substrate.

Step 3: Cut Panels to Height

What it accomplishes: Panels cut cleanly with a fine-tooth saw and need to be measured precisely to avoid gaps at the ceiling line or skirting.

Measure floor-to-ceiling height at three points across the wall — UK houses rarely have perfectly consistent ceiling heights. Use the shortest measurement as your cut length. Mark with a sharp pencil against a straight edge, then cut with a fine-tooth mitre saw or hand saw. Cut with the decorative face up when using a hand saw; decorative face down on a circular saw (to avoid tear-out on the visible surface). Dry-fit 2–3 panels before applying any adhesive to confirm the fit.

Common mistake: Measuring once. Always measure at least twice at different points, especially on older properties where walls lean.

Step 4: Apply Panel Adhesive

What it accomplishes: High-tack adhesive creates a permanent bond without visible fixings and keeps the clean slatted aesthetic intact.

Load a 290 ml cartridge of high-tack panel glue into a standard caulking gun. Apply a serpentine bead to the back of each panel, staying 50 mm from the edges. One 290 ml cartridge covers 2–3 panels depending on how heavily you apply it. Press the panel firmly onto the wall (or batten frame), hold for 30–60 seconds, then use temporary support props or masking-tape strips to hold position while the adhesive grabs — typically 15–30 minutes for initial set, 24 hours for full cure.

Common mistake: Applying adhesive too close to panel edges. Squeeze-out at the joints leaves a visible residue in the slat gaps.

Step 5: Work Left to Right, Checking Level Every Third Panel

What it accomplishes: A spirit level check every third panel catches any drift early — fixing a misaligned panel after full cure means cutting it off.

Start from the most visible corner of the wall. Butt panels tightly edge-to-edge; the tongue-and-groove or flat-edge system on Aku Wood Panel slats keeps joints tight. Check vertical alignment with a spirit level after fitting panels 1, 3, and 6. If a panel needs a small correction while the adhesive is still wet (within the first 5 minutes), slide it — do not lever. Mark batten positions lightly in pencil on the floor so you know exactly where fixings are.

Common mistake: Starting from the wrong end. If your wall is not a whole-panel multiple, you want any cut panel at the least visible edge — usually a corner meeting a door frame.

Step 6: Fit End Pieces and Trim

What it accomplishes: End pieces cap the open slat ends at edges and corners for a factory-finished look and prevent dust accumulation in the exposed slat channels.

End pieces are available in matching finishes — Walnut, Smoked Oak, Black Oak, Natural Oak, Grey Oak, and others — and clip or glue directly onto the panel edge. Cut to height the same way as the main panels. At external corners (e.g. where a panelled media wall meets a return wall), mitre both panels at 45° for a clean joint, or use a dedicated corner trim. Allow 3 mm expansion gap at the floor to account for seasonal movement; the skirting board will cover it.

Common mistake: Omitting end pieces on a visible edge. The raw slat ends are noticeably unfinished and collect dust within days.

Step 7: Reinstate Sockets and Blanking Plates

What it accomplishes: Any mains sockets or data ports that sit on the panelled wall need surface-mount back boxes to bring them flush with the new panel face.

Use surface-mount electrical back boxes (20 mm depth is standard) to extend sockets forward by the panel thickness — typically 21 mm for Aku Wood Panel slatted panels. This is the only step that requires a qualified electrician if you are moving or extending a mains circuit; if you are only extending the socket face forward using a surface-mount box on an existing fused spur, most competent DIYers can do this themselves. Confirm compliance with Part P of the Building Regulations. Once reinstated, label the cable route on the back of the nearest removable panel or in a maintenance file.

Common mistake: Using a flush back box and ending up with a socket that sits 20 mm recessed behind the panel face — visually poor and potentially a fire risk if the socket overheats in a confined void.

Troubleshooting

Panel is bowing away from the wall after 48 hours. The adhesive has not bonded — usually a damp or dusty substrate. Remove the panel, clean both surfaces, allow to dry, and reapply adhesive. Use the batten method if the wall is brick or uneven.

Slats are not lining up horizontally across panels. Panels were not started from a level datum line. Use a laser level or chalk line at the base of the first row before fitting any panels.

Adhesive is visible in the slat gaps. Too much adhesive applied too close to the edges. Score off dried excess with a sharp craft knife; prevent it on future panels by stopping the bead 50 mm from all edges.

A cable run creates a visible ridge under the panel. The cable or conduit is too thick for the service void. Switch from flat oval cable (9 mm) to round cable (6 mm) or re-route the run behind a batten to create more depth.

Panel has shifted before the adhesive cured. Prop or tape panels in place for at least 30 minutes after fitting. In a cold room (below 10°C), adhesive cure time extends significantly — work at above 15°C where possible.

A panel needs removing to access a fault on a hidden cable. If you photographed the cable routes in Step 1 and documented them, you will know exactly which panel to remove. Slide a thin spatula behind the panel to break the adhesive bond — do not force or the panel will split. Refit with fresh adhesive.

What to Do Next

Once the panels are up and cables are concealed, the next step most people tackle is lighting — recessed LED strip in the slat gaps or up-lighters at floor level to bring out the grain.

FAQ

Can you hide cables behind wall panels without chasing the wall? Yes. Slatted wood panels sit 20–30 mm proud of the wall, and that void is enough to carry flat-oval cable, HDMI leads, and ethernet. No chasing required.

What thickness of cable void do wall panels give you? Direct-adhesion fitting gives a void of approximately 20–25 mm. A batten-frame installation gives 50–75 mm, which is enough for pipe lagging or multiple cable bundles.

Do you need an electrician to panel over mains cables? Not for the panelling itself. You need a qualified electrician if you extend, move, or add to a mains circuit. Extending a socket face forward with a surface-mount back box on an existing fused spur is generally a DIY task under Part P, but confirm with your local authority.

Are wall panels safe to use around pipes? Yes, provided pipes are photographed and documented before covering, expansion joints are respected, and no panel adhesive contacts the pipe directly. Always leave pipe runs accessible at service points (valves, junctions).

Which Aku Wood Panel finish works best for a media wall in 2026? Black Oak is the most popular choice for media walls in 2026 — the dark tone reduces reflections on screen and hides the cable management void visually. Natural Oak reads warmer and suits living-room feature walls.

How long does it take to panel a 3 m² wall and hide cables? Allow 2–3 hours for cable securing and surface prep, plus 1–2 hours for fitting panels. Full adhesive cure is 24 hours before you should apply load or fit sockets.

Can I remove the panels later if I need to access cables? Yes. A thin spatula or pry bar breaks the adhesive bond without damaging the wall, and the panels can generally be refitted with fresh adhesive. Document cable routes before covering for faster future access.

Do wall panels work in rental properties where you cannot chase walls? Yes — the adhesive-mount method causes minimal damage, and panels can be removed at the end of a tenancy. Check your tenancy agreement before fixing battens with screws into masonry.

One Last Thing

Acoustic slatted panels absorb mid-frequency sound (250 Hz–2 kHz) as well as hiding cables — the felt backing layer on grey-felt variants is rated at NRC 0.65, meaning they absorb 65% of incident sound in that range. A media wall that also reduces echo is a genuine dual benefit, not a marketing claim. If your room has hard floors and a high ceiling, the acoustic gain from a single 3 m² panel run is measurable.
