Engineered stone is made in batches
Two slabs of the same named quartz or sintered surface, from different production batches, can differ in tone and in the scale of the pattern. It is not a fault, it is manufacturing.

Stone running up the wall, cut from the same slab run as your worktop so the colour and the scale of the pattern actually match under your own lights.
An upstand is a shallow strip of your worktop material that sits on the surface against the wall, commonly around 100mm high and cut to whatever height suits your tiling line or window sill. It replaces the bottom row of tiles and, more usefully, it hides the junction between worktop and wall, which is always the least straight line in the kitchen.
A full-height splashback runs from the worktop up to the underside of the wall units, or behind the hob from the surface to the extractor. No grout, no tile joints, nothing to scrub. It costs more because it is priced by area, and it demands an accurate template of every socket and switch.
Most kitchens end up with a mix: upstands along the general runs, and a full-height piece behind the hob where the mess actually happens.
Fitted 5–10 working days from template. Deposit at template, balance before installation.
What is involved
The decision belongs at quotation stage, because it changes the tiling plan and the tiler is usually booked before anyone thinks about it.
Upstands, a full-height splashback or tiles: this changes what the wall needs and in what order. Deciding late is how people end up paying for tiling they then cover up.
Taken in the same visit wherever possible. Any full-height piece is templated to the actual wall, with real socket, switch and extractor positions rather than the ones on the plan.
Your upstands and splashbacks are nested onto the same material as the worktop, at the same time, so the colour and the pattern scale carry through.
Cut-outs for sockets, switches and anything else breaking the face of a splashback, machined to the same drawing.
Bonded to the wall once the surface below is fitted and levelled, scribed where the wall demands it, and sealed at the junction with the worktop.
The joint between worktop and upstand is a movement joint and it is siliconed, not grouted. Grout there cracks, which is exactly the failure the stone was meant to remove.
Batch matching
This is the single most useful thing to understand before you decide to add them later.
Two slabs of the same named quartz or sintered surface, from different production batches, can differ in tone and in the scale of the pattern. It is not a fault, it is manufacturing.
A slight batch variation two metres away across a room is invisible. The same variation where an upstand meets the worktop it sits on, under downlights, is obvious and you will never stop seeing it.
Quarried stone varies from slab to slab by nature. There is no production run to quote and no way to reorder a match, so cutting everything together is the only route.
If you decide six months on we will happily cut it, but we cannot promise the batch will match, and we would tell you that before taking any money rather than after fitting it.
If a window sits in a run, its sill can be cut from the same material at the same time. It is a small addition at that point and a much larger one afterwards.
Granite and sintered surfaces take direct heat without complaint. Engineered quartz has a resin binder and is happier not sitting inches from a gas ring under sustained heat. If your chosen colour is the wrong one for that particular spot, we will say so before you buy it.
Getting it right
A splashback is unforgiving of late changes, because a moved socket means a new piece rather than an adjustment.
Questions
If yours is not here, ring and ask. You will get a straight answer rather than a call-back from a salesperson.
Commonly around 100mm, but they are cut to whatever suits the room. Many people set the height to meet a window sill or to line up with the bottom of a tile course. It is decided at template and costs the same either way within normal heights.
You can, and we will cut it. What we cannot promise is a batch match, because engineered stone is produced in batches and granite varies slab to slab. Where pieces touch, that difference shows. Ordering with the worktop is the only way to guarantee it.
With a full-height splashback in the working runs, usually not. With upstands you will still want something above them, whether that is tile or paint. It is worth deciding before the tiler is booked rather than after.
Yes. They are templated with the worktop and machined in the workshop. The positions have to be final at that point, because moving a socket afterwards means cutting a new piece rather than adjusting the fitted one.
Where this happens
Twelve neighbourhoods whose housing stock throws up this job most often. Each page covers what splashbacks & upstands actually involves in that stock: the access, the era of the building and what that does to the work.
These twelve are a sample, not a coverage boundary. We work in 723 Greater London neighbourhoods and out into Surrey, Hertfordshire, Buckinghamshire, Berkshire and Essex.
