The short answer
Brick slip cladding uses thin slices of brick — typically around 15–25mm deep — bonded to a wall, a backing board or an insulated panel, then pointed with mortar to look like a full brick wall. The slips can be cut from real fired clay bricks or made as replica brick tiles, giving an authentic masonry appearance at a fraction of the weight and thickness of true brickwork. It is popular for extensions, feature walls, and matching new work to existing brick, and for adding a brick face over insulation. Because it is fired clay (or mineral-based), real brick slip is durable, low-maintenance and non-combustible. The look depends heavily on good installation and neat pointing, and labour can make it one of the more expensive finishes to fit.
Brick slips let you get the solidity and kerb appeal of brick without the cost, weight or thickness of a full masonry wall. Here is how the system works.

How brick slip cladding works
A brick slip is essentially the face of a brick with the depth removed. Slips are produced either by cutting thin slices from full bricks or by manufacturing brick-effect tiles. They are fixed to the substrate — a wall, a mechanically fixed backing panel, or a pre-bonded insulated board — using adhesive or a rail system, then the gaps are filled with mortar pointing to replicate the joints of real brickwork. Corner pieces are made to wrap around external angles so the result looks like solid brick. Once pointed, a good installation is difficult to distinguish from a built brick wall.
Why people use it
Brick slips solve several common problems:
- Brick look without the weight — far thinner and lighter than a brick skin, so it can go where full brickwork cannot.
- Matching extensions — slips cut or chosen to match existing brick blend old and new together.
- Brick over insulation — slips on insulated panels give external wall insulation a traditional brick face.
- Durable and non-combustible — fired clay slips do not rot, fade much or burn, and need little upkeep.
The main downsides are labour cost (pointing is skilled, time-consuming work) and the need for a sound, correctly prepared substrate so slips do not debond.
Types of brick slip and fixing systems
Brick slips come in a few forms and can be fixed in different ways. Cut clay slips are sliced from genuine fired bricks and give the most authentic colour, texture and durability. Extruded or moulded brick tiles are manufactured directly as thin slips, offering consistency and a wide range of styles. There are also mineral or polymer-based replica slips for lighter applications. For fixing, the simplest method is bonding slips with adhesive to a sound, prepared substrate and then pointing the joints. A more robust approach on larger areas or over insulation uses a mechanical rail or carrier panel system, where slips clip or bond into a backing board that is fixed to the wall; this can also incorporate insulation, turning the brick face into part of an external wall insulation build-up. The right system depends on the substrate, the area, whether insulation is involved and the fire requirements of the building.
Cost and performance
Material cost is moderate, but the labour to fix and point slips pushes the fitted price up.
| Factor | Brick slip cladding | Notes |
|---|---|---|
| Fitted cost | ~£80–£150/m² | labour-heavy to point |
| Weight | Light vs full brick | suits panels and EWI |
| Fire | Clay slips non-combustible | check system components |
| Maintenance | Very low | occasional repointing if needed |

Getting the look right
A brick slip wall stands or falls on two things: the choice of slip and the quality of the pointing. To blend new work with an existing brick house, slips are chosen — or genuine bricks cut — to match the colour, texture and size of the original brickwork, and the mortar joint is matched in colour and profile too, since the pointing is as visible as the brick itself. Skilled pointing produces consistent joint widths and a clean, struck or flush finish that reads as solid brickwork; rushed or uneven pointing is the giveaway that betrays a slip system. Corner pieces wrap external angles so the wall looks full-depth, and reveals around windows and doors are detailed to maintain the illusion. Because so much depends on workmanship, brick slip is a finish where the installer's skill matters as much as the product, and it is worth seeing examples of a fitter's previous work before committing.
Maintenance and durability
One of brick slip's strengths is that, once installed, it asks for very little. Fired clay slips share the durability of full brick — they do not rot, fade much, or burn, and they shrug off frost and UV — so the wall typically needs only occasional cleaning. The main long-term attention is to the pointing: as with any brickwork, mortar joints can eventually need localised repointing if they crack or erode, and any movement in the building should be accommodated by movement joints so the slips are not stressed. A well-installed clay brick slip wall on a sound substrate can last for decades looking much as it did on day one, which is part of why it is chosen for both appearance and longevity. The durability does depend on the quality of the original fixing and substrate preparation, so getting the installation right is what protects the low-maintenance promise over the years.
Is brick slip right for your home?
Brick slip cladding suits anyone who wants the permanence and kerb appeal of brick but cannot or does not want to build a full masonry wall — common on extensions, infill panels, garden rooms and external wall insulation. Real clay slips give the most authentic, durable result and are non-combustible, which helps on fire-sensitive buildings, though you should check the fire performance of the whole system, including any backing board and adhesive. The finish stands or falls on the quality of the pointing, so use an experienced installer. As with all external work, fixing must comply with Building Regulations, and the substrate must be sound and correctly prepared.
Frequently asked questions
Is brick slip cladding as good as real brick?
Visually a well-pointed brick slip wall is very hard to tell from real brick, and clay slips share brick's durability and low maintenance. It is not structural — it is a face finish bonded to a backing — so it is used as a cladding, not to carry load, but for appearance it performs extremely well.
Does brick slip cladding fall off?
Properly installed on a sound, prepared substrate with the correct adhesive or fixing system, brick slips are very durable and stay put for decades. Debonding is usually a result of a poor substrate, wrong adhesive or bad workmanship, which is why correct preparation and an experienced installer matter.
Is brick slip cladding fireproof?
Clay brick slips are non-combustible, but a brick slip system also includes backing panels and adhesives that may not be. No cladding is absolutely fireproof, so on flats or taller buildings check the certified fire performance of the complete system, not just the brick face.
