The Construction Industry Scheme covers a wide range of construction activity – but not all of it. HMRC has carved out a number of exemptions for work that falls outside the definition of a construction operation. And one of the more unusual ones concerns artistic works. It is not an exemption that comes up every day, but when it does, understanding it correctly can save a contractor from making unnecessary deductions. Or, just as importantly, from failing to make deductions they should be making.
What is the Artistic Works Exemption?
HMRC’s position is that works which are wholly artistic in nature, i.e. they serve no functional purpose associated with a building, are not regarded as construction operations and therefore fall outside CIS. This is not a formally codified rule with a single stated test. Rather, it emerges from HMRC’s guidance and examples, which draw a distinction between work that exists purely as art and work that also performs a building function.
The distinction HMRC applies is broadly functional in character. If a piece of work serves a normal functional purpose associated with a building – even if it is also artistically significant – then the exemption is unlikely to apply. If it exists purely as an artistic work with no functional role in the building, it is more likely to sit outside the scheme. In practice, the line is not always obvious, and contractors should take care not to apply the exemption too broadly.
HMRC’s Examples to Illustrate Artistic Exemption
HMRC’s own guidance uses two examples that illustrate the distinction clearly.
The first is a statue commissioned alongside a new building. A statue has no function other than to be enjoyed as a work of art. It does not support the structure, provide shelter, let in light, or serve any practical purpose associated with the building. Its creation and installation are therefore not construction operations and fall outside CIS.
The second is a stained glass window. A stained glass window has genuine artistic merit – it may be beautiful, historically significant, and created by a skilled craftsperson. But it is still a window. It lets in light, it fills an aperture in a wall, it performs a function that is common to buildings generally. That functional purpose means it falls within CIS, regardless of its artistic value.
Further Examples — Inside and Outside CIS
Applying the same principles as in the HMRC examples, here is how various types of work with artistic merit tend to fall:
Likely Outside CIS
- A freestanding sculpture or installation commissioned for a building’s foyer or grounds, with no structural or functional role and removable without construction work.
- Canvas murals or paintings hung within a building that exist entirely as art.
Likely Inside CIS
- Decorative ironwork on gates or railings – however ornate, gates and railings serve a functional purpose.
- Decorative or artistic tiling – tiles perform a protective and waterproofing function regardless of their design.
- Mosaics applied to walls or floors – HMRC’s guidance indicates these are generally treated as having a protective or structural purpose similar to tiling, meaning they are more likely to fall within CIS than outside it.
- Ornamental stonework that forms part of the building’s structure – a carved stone lintel is still a lintel
- Any artwork integrated into a functional building element – decorative brickwork patterns, etched glass doors, artistic ceiling panels that also provide acoustic insulation.
A Word on the Judgment Cal
It is worth being clear that the decision on whether a particular piece of work falls within or outside CIS rests with the contractor – not with HMRC. HMRC’s subcontractor verification process confirms the deduction rate to apply to a subcontractor (0%, 20%, or 30%), but it does not confirm whether the work being commissioned falls within CIS at all. That determination is the contractor’s responsibility, and getting it wrong in either direction can carry consequences.
Where there is genuine uncertainty, the safest approach is to take professional advice or contact HMRC’s CIS Helpline on 0300 200 3210 before work begins.

The Mixed Contract Question
One issue that catches contractors out is the mixed contract. If a single contract covers both artistic work and construction work that falls within CIS, HMRC may treat the entire contract as within the scheme. However, this is not an absolute rule – it applies where the elements are not clearly identifiable and separable. Where the artistic element is properly described and separately itemised, it may retain its exempt character even alongside construction work.
It is also important to note that specifically excluded professional services – including genuine artistic commissions that qualify as professional services – retain their exempt status separately from the mixed contract rule. A standalone artistic commission engaged under its own terms is less likely to be pulled into CIS by associated construction work than a supply of materials or physical labour would be.
How to Reduce the Risk of Getting It Wrong
The practical steps for contractors dealing with artistic commissions alongside construction work are:
- Separate contracts where possible. Where artistic work that may fall outside CIS is being commissioned alongside construction work, a separate contract clearly describing the nature of the artistic commission gives the clearest protection. This is good practice, though not a guaranteed safeguard on its own – HMRC looks at the substance of the arrangement rather than purely its form.
- Be specific about what is being created. The contract for artistic work should clearly describe the nature of the commission, for example a freestanding sculpture, a canvas installation, a painted mural. It should confirm that it has no functional building purpose. The clearer the description, the more straightforwardly the exemption argument can be made if it is ever questioned.
- Document your reasoning. Where you make a judgment that work falls outside CIS, keep a record of why you reached that conclusion – the nature of the commission, how it is installed, whether it could be removed without construction work, and what functional purpose (if any) it serves. If HMRC ever reviews the position, a clear documented rationale is far more useful than a vague recollection.
Take advice where the position is unclear. The artistic exemption is genuinely uncertain in some cases – particularly for applied artworks like murals and mosaics. Where the position is unclear, taking professional advice before commissioning the work is considerably cheaper than dealing with a compliance issue after the fact.
The artistic works exemption is a legitimate but narrow carve-out from CIS. Used carefully for genuinely artistic work that serves no functional building purpose, it removes an administrative burden that serves no real tax purpose. Applied too broadly, it can create exactly the compliance problem it was meant to avoid.
