Splashbacks & Upstands – What to Expect – August 15th FAQs

In this feature we will look at some of the most commonly asked questions among the hundreds of homeowners and trade customers whom we deal with on a weekly basis.

Why are there gaps behind my upstands?

This customer issue is one which quite a few people bring up. When you imagine a new kitchen, the last thing you expect to see is that your dream surfaces don’t quite fit the room.

Upstands are joined to either the wall, or to the worktops themselves, depending on the material. Because in either case they are a single run of straight, inflexible material, often once these are installed there may be gaps either across the length, or at either side.

In mild scenarios, the wall beneath may be uneven. This would result in small breaks of contact between the upstand and the wall.

In more severe situations, the wall may be concave or convex. A concave wall would mean a large gap towards the centre of the upstand. A convex wall can often be the worst case scenario, as bulging in the centre means the worktop has either noticable gaps at either side, or an extreme gap at one side.

In any of the above situations, the reason for the gap is the wall beneath and not the worktop itself.

What can I do about the gaps behind my upstands / splashbacks?

Any such gaps are usually caused by uneven plastering, and can be remedied by a decorator. Common solutions are:-

  • Using decorators caulk to fill the gaps.
  • Replastering to even out the surface (may be necessary for larger convex or concave wall issues).
  • Tiling above or around your splashbacks and/or upstands.


How far can my Splashback be from the hob?

Any splashbacks over 100mm high need to have a minimum gap from the face to the rear of the hob. For both electric and gas hobs this is a minimum of 50mm.

This measurement takes into consideration that appropriate pans are used on the correct hobs, such that heat is not unnaturally directed towards the upstand. Subjecting splashbacks to high temperatures for sustained periods of time can cause damage.
