Indoor & Interior Signs
Indoor Signs UK
Types of Indoor Signs London We Manufacture and Install
-
3D Lettering and Built-Up Letters
Three-dimensional lettering creates immediate visual impact in reception areas and lobbies. We manufacture 3D letters from acrylic, brushed aluminium, and PVC foam in thicknesses from 5mm to 50mm. Typical pricing starts at £180 for small acrylic letter sets and ranges to £850+ for large aluminium installations with LED backlighting. Popular finishes include matt, gloss, metallic, and custom Pantone colour matching.
-
Wall Graphics and Vinyl Manifestations
Self-adhesive vinyl signs transform plain walls into branded environments. We print on high-grade polymeric vinyl that won’t shrink, fade, or peel, even in high-traffic areas. Wall graphic projects typically range from £120 for small decals to £600+ for full wall coverage. These indoor signs are particularly effective in corporate meeting rooms, retail changing areas, and creative studio spaces.

Wayfinding and Directional Signage
Clear directional signage reduces confusion and improves building flow. We design comprehensive wayfinding systems using Dibond, aluminium composite, and acrylic panels with professional vinyl graphics or direct UV printing. Complete wayfinding packages for medium-sized offices typically range from £450 to £1,200, depending on the number of signs and fixing requirements.
-
Illuminated Interior Signs

LED signs deliver 24-hour visibility and premium aesthetics. Our edge-lit acrylic panels, lightbox systems, and halo-lit letters create striking focal points.

All electrical work complies with BS 7671 regulations and includes certification.

Professional door signs and desk nameplates are available in acrylic, brushed stainless steel, and aluminium composite. We offer wall-mounted, suspended, and insert fixing options.
