Wall Panelling Guide Berkshire: Slat, Jacobean, and Tongue & Groove Costs

Tongue-and-groove vertical panelling is the most traditional form — boards of 90–120mm width with a machined joint, painted or stained, running from floor to dado rail or full height. Cost: £80–£140 per square metre installed. Acoustic timber slat panels (vertical oak slats on a felt backing) are the current trend specification — premium aesthetics with some acoustic benefit. Cost: £120–£200 per square metre. Raised-and-fielded Jacobean-style panelling — framed panels with a profiled raised centre — is the most labour-intensive and most architecturally impressive. Cost: £180–£300 per square metre.

The dado rail height — where the upper wall meets the lower panelling zone — has a significant effect on room proportions. At 900mm (standard dado height), panelling creates a horizontal datum at approximately one-third of wall height, which suits most ceiling heights. At 1100–1200mm in a room with 2.6m+ ceilings, the proportion is more generous and the panelling looks more architectural. Full-height panelling from floor to ceiling creates a completely panelled room and requires a very precise specification to avoid looking like a hotel corridor.

Every panelling project starts with a full site survey rather than a standard drawing pulled off the shelf. We measure the room at multiple heights and points along each wall, because older Berkshire properties rarely have perfectly square corners or true walls — a wall that looks straight to the eye can be out by 20–30mm over its length, and the panelling layout has to accommodate this rather than fight it. We note the position of every socket, switch, radiator, skirting profile, door and window reveal, and any services running within the wall, since these all dictate where panel joints and battens can and cannot fall.

From the survey we produce a setting-out drawing showing panel widths, joint positions, and how the layout resolves around doors, corners, and any fireplace or chimney breast. Getting this stage right matters more than any other part of the process — a panelling scheme with awkward, unequal panel widths at a corner or window reveal looks amateurish however well the individual panels are made, whereas a well-resolved setting-out drawing means the finished room reads as a single considered composition.

Moisture-resistant MDF is the standard material for painted panelling of any style — it machines crisp mouldings, takes paint beautifully, and is dimensionally stable in normal room conditions, which matters because panelling spans wide, unbroken runs of wall where any movement shows immediately as a hairline crack along a joint. Solid timber (oak, in particular) is used where the panelling is to be left in a natural or lightly oiled finish, most commonly for slat panelling, and occasionally for a Jacobean scheme where the client wants genuine solid oak framing rather than a painted finish.

Veneered MDF or veneered ply — a thin layer of real timber bonded to a stable MDF or ply substrate — offers a middle ground: the appearance of solid oak or walnut grain with the dimensional stability of an engineered board, at a lower material cost than solid timber throughout. This is a sensible specification for larger panelling runs where a natural finish is wanted but a full solid-timber specification would push the budget considerably higher without a meaningful difference in appearance or performance.

Acoustic slat panelling consists of vertical timber slats, typically 20–40mm wide with a similar or slightly narrower gap between them, fixed to a felt or acoustic-fabric backing panel. The reveal (gap) width and the slat profile — square-edged, chamfered, or rounded — have a significant effect on the finished look, and we always build a small sample panel before committing to a full room so the client can see the exact rhythm and shadow line in situ. Slat panelling is generally left in a natural oak or walnut finish, since painting it removes much of what makes the style distinctive, though a painted specification is occasionally requested for a more contemporary, monochrome look.

Slat panelling works particularly well behind a bed headboard, in a hallway, or as a feature wall behind a media unit, and integrates cleanly with concealed LED lighting run within the slats or along the top edge. Because the acoustic backing panel sits proud of the wall, slat panelling is also a useful way of disguising a wall that is out of true, since the slats read as a deliberate rhythm rather than drawing attention to any underlying unevenness.

Raised-and-fielded panelling — the traditional Jacobean style — is built from individual timber frames with a mortice-and-tenon or stub-tenon jointed stile-and-rail construction, into which a raised, profiled "fielded" panel sits in a groove, allowed to move independently of the frame as timber naturally expands and contracts with seasonal humidity. This traditional construction is what gives genuine Jacobean-style panelling its longevity and its refusal to crack, unlike a panel glued rigidly into a fixed frame.

The moulding profile run around each frame member — an ovolo, ogee, or bolection mould — is what gives the style its depth and shadow, and is typically run to match or complement other joinery already in the property, such as door frames or a staircase. This is the most labour-intensive panelling style we offer, reflecting the framing, jointing, and moulding work involved, and suits grand reception rooms, studies, and dining rooms in period properties where the architectural weight of the room calls for it.

Tongue-and-groove (T&G) panelling is boards machined with a matching tongue and groove along each long edge so they interlock and are fixed with a hidden nail or pin through the tongue, leaving no visible fixings on the face. Board width (commonly 90–120mm) and the amount of "vee" or chamfer at each joint determine how strong the vertical lines read — a tight vee gives a subtle, almost seamless look, while a deeper chamfer gives a more pronounced beadboard character often associated with utility rooms, boot rooms, and coastal-style interiors.

T&G is the most straightforward and cost-effective panelling style to install well, which is why it remains the most commonly specified across Berkshire hallways, boot rooms, and dado-height dining rooms. It is finished with a top rail (or dado cap) and usually a matching skirting detail below, both of which should be specified and ordered as part of the same run so the mouldings relate properly to one another.

The most common mistake is commissioning panelling from a standard-width panel system without first checking how it resolves at corners, around windows, and against existing skirting and architrave — leaving an awkward sliver panel in a corner or a mismatch in height against the existing joinery. A proper setting-out drawing at survey stage avoids this entirely, which is why we treat it as a non-negotiable step rather than an optional extra.

A second frequent error is specifying standard (non-moisture-resistant) MDF or ordinary paint in a bathroom, kitchen, or other humid space — this leads to swelling and delamination at joints within a year or two. A third is ignoring existing services: panelling fitted straight over sockets, switches, or thermostats without repositioning them first is both impractical and, depending on the fixture, potentially unsafe. Finally, undersizing the expansion allowance in solid timber panelling — particularly Jacobean raised-and-fielded work — causes panels to crack or bow as they respond to seasonal humidity changes; this is precisely why the traditional floating-panel construction exists, and why it should not be value-engineered out of a specification.

Once the design is approved, panelling is usually built in the workshop as complete sections or frames rather than assembled entirely on site — this keeps the time spent in the client's home to a minimum and means the bulk of dust and noise happens off-site. Installation begins with fixing battens or grounds to the wall, packed out as needed to true up any unevenness, followed by fixing the panel sections to the battens, scribing the end panels to any out-of-square corners, and fitting the top rail, dado cap, and skirting.

Once fixed, joints and fixing points are filled and caulked, and the whole run is primed ready for finish painting or, for a natural timber scheme, sanded ready for oiling. A typical dining room or hallway installation takes one to two days to fit and prime, with a further day for spray-painting or oiling, though a full-height Jacobean scheme in a large room takes correspondingly longer given the volume of framing and moulding involved.

Correctly specified and installed panelling is genuinely long-lived joinery — decades rather than years — provided the material and finish suit the room. Painted panelling needs only an occasional wipe down and a repaint every several years depending on wear and light exposure; natural oak slat or Jacobean panelling benefits from a light re-oiling every one to two years to keep the timber fed and the colour even. In bathrooms and kitchens, keeping extraction working properly and wiping away standing water promptly does more for the panelling's long-term condition than any specification choice.

Because panelling is built from separate, jointed sections rather than a single rigid sheet, minor damage — a scuff, a small dent, or a chipped moulding edge — can usually be repaired locally without replacing an entire wall's worth of panelling, which is one of the practical advantages of a properly built traditional system over a single continuous sheet product.

Panelling reads best when it is planned alongside, rather than after, the rest of a room's joinery — skirting, architrave, door styles, and staircase details. Matching the panelling's moulding profile and paint colour to existing doors and skirting turns a single panelled wall into part of a coherent scheme rather than an isolated feature. Where a fireplace, radiator, or built-in cabinetry sits within the panelled wall, these are set out at the design stage so panel joints align sensibly with their edges rather than clashing with them.

In many of the Berkshire homes we work in, panelling in a hallway or dining room becomes the starting point for a wider joinery scheme carried through into a study, boot room, or staircase, with the paint colour and moulding profile repeated so the whole ground floor feels considered as one piece of design rather than a series of separate purchases.

The per-square-metre figures above cover materials and standard installation, but total project cost also depends on wall condition (a wall needing significant packing out or replastering adds time), the number of corners, reveals and obstructions to work around, and whether existing skirting, architrave or a dado cap need replacing to match. Painted finishes add a spraying or brush-finishing cost on top of the base joinery rate; natural oak finishes generally cost less to finish but more in base material.

As a rule, T&G is the most cost-effective style per square metre, acoustic slat sits in the middle reflecting the backing panel and typically higher-grade timber finish, and Jacobean raised-and-fielded panelling is the most expensive given the framing and moulding labour involved. We always provide a room-specific quotation after survey rather than a blanket per-metre estimate, since the obstructions and setting-out complexity in a real room can move the price meaningfully in either direction.
