A gilding and decorative arts conservator specialises in the conservation and restoration of the gilded surfaces, painted decorative schemes and ornamental interiors found in country houses, churches, theatres and other historic buildings. This highly specialised field combines a practical knowledge of historic gilding techniques (water gilding, oil gilding, silver gilding), decorative painting, and conservation science. The conservator follows the minimum-intervention principles of the Institute of Conservation (ICON), aiming to preserve original material rather than replace it.
What they do
- Survey and assess gilded and decorated surfaces in historic buildings
- Clean and consolidate deteriorating gilded surfaces
- Restore water-gilded and oil-gilded architectural features
- Conserve and restore historic painted decorative schemes
- Produce new water gilding to match surviving original
- Conserve gilded picture frames, mirror frames and furniture
- Carry out inpainting to fill losses in decorative painted surfaces
- Write conservation reports and treatment plans for grant applications
When you need one
A gilding and decorative arts conservator is needed for any work on gilded or decorated historic interiors where the original material must be preserved.
Typical costs (UK, 2025)
| Service | Typical cost |
|---|---|
| Conservation survey and report | £300 - £700 |
| Gilding conservation (per sq m) | £200 - £600 / sq m |
| New water gilding (per sq m) | £300 - £800 / sq m |
| Decorative painting conservation (per sq m) | £150 - £400 / sq m |
| Conservation treatment plan | £400 - £900 |
| Day rate for conservation works | £300 - £500 / day |
Conservation gilding is time-intensive craft work. Large country house projects may take weeks or months. Costs per square metre vary with the condition of the original, the complexity of mouldings and the level of original material to be preserved.
Qualifications to look for
ICON accreditation (ACR) is the professional standard for conservation in the UK. Accredited conservators have demonstrated competence through peer assessment. Find accredited conservators at icon.org.uk.
The Victoria and Albert Museum Conservation Register lists approved conservators working in decorative arts and historic interiors - a useful resource for finding gilding and decorative arts specialists.
Frequently asked questions
What is the difference between water gilding and oil gilding?
Water gilding uses gold leaf applied over a clay (bole) ground on a water-moistened surface, which is then burnished to a high mirror finish - the traditional technique for high-quality decorative work. Oil gilding uses gold leaf applied over gold size (adhesive) and cannot be burnished - more durable externally but less lustrous than water gilding.
How long does gilding last?
Gold itself is stable and non-tarnishing. The finish deteriorates when the underlying layers fail or moisture penetrates. Well-applied water gilding can last centuries if protected from moisture and abrasion. External oil gilding typically needs renewal every 5-15 years depending on exposure.
What conservation approach is used for historic gilding?
ICON conservation ethics require minimum intervention - cleaning and consolidating surviving original material is always preferred over replacement. New gilding is applied only where original is completely lost. All interventions should be documented and be reversible where possible.
