Cavity Floor Boxes & Floor Sockets

When power and data are needed away from walls, cavity floor boxes offer a clean, safe, and practical solution. In offices, commercial spaces, hotels, and modern homes, floor sockets help deliver electricity, data, and AV connections exactly where people work and gather.

At EWS- Electrical Wholesale Supplier in the UK, from recessed floor outlets in concrete slabs to flush floor boxes for wood and raised floors, the right floor box improves accessibility, protects cables, and keeps spaces uncluttered. Whether you’re fitting out an open-plan office or upgrading a conference room, well-chosen floor sockets make installations safer, neater, and future-ready.

Complete Range of Cavity Floor Boxes

Finding the correct floor electrical box often depends on floor type, load requirement, and service needs. That’s why this category brings together solutions for concrete, screed, raised, carpet, and wood floors in one place.

Our range includes recessed floor boxes, flush floor outlets, round and square floor boxes, and surface mount floor boxes. Options are available for power-only or combined power and data floor boxes, making coordination between electrical, IT, and AV teams much easier.

Each floor box is designed to sit securely within the floor cavity, protect connections, and allow safe access throughout the life of the building.

Floor Sockets for Power, Data & AV

Power Floor Outlets

A floor power outlet provides convenient access to mains power without trailing extension leads. Popular choices include 2 gang floor sockets, double floor sockets, and 13 amp floor sockets, suitable for commercial and residential use.

Data & Low-Voltage Floor Boxes

Modern spaces demand more than power alone. Data floor boxes support RJ45, Cat6, Cat6A, HDMI, USB, and AV connections. These are ideal for meeting rooms, workstations, and teaching spaces where clean cable management matters.

AV & Stage Floor Boxes

For events, studios, and performance areas, XLR floor boxes, audio floor boxes, and stage floor boxes allow reliable signal routing while keeping floors clear and safe.

Recessed & Flush Floor Box Solutions

A recessed floor outlet sits level with the finished floor, reducing trip hazards and protecting cables from damage. Flush floor boxes are especially popular in offices, hotels, and retail spaces where appearance matters.

Options include brass floor boxes, stainless steel floor sockets, and black or brushed metal floor outlet covers. Many designs support tile, carpet, vinyl, and wood finishes, helping installations blend seamlessly with interior design.

Floor Boxes for Concrete, Screed & Raised Floors

Different floors need different solutions. Concrete floor boxes and screed floor boxes are cast-in or recessed during construction, providing long-term durability. These are common in commercial buildings and public spaces.

For flexible layouts, raised floor boxes allow easy reconfiguration of power and data as office needs change. Shallow and low-profile floor boxes are also available where floor depth is limited.

Safety, Protection & Compliance

Floor-mounted electrical outlets must handle foot traffic, cleaning, and daily use. That’s why many options feature fire-rated floor boxes, IP-rated floor sockets, and lockable floor box covers.

Proper sealing helps prevent dust and moisture ingress, while strong covers protect internal wiring. Using compliant floor boxes supports safe installations and simplifies inspections under UK regulations.

Buying Guide: Choosing the Right Floor Box

Start by identifying the floor type—concrete, screed, raised, or wood. Then consider the services required: power only, or power and data floor boxes.

Next, check load ratings, IP protection, and whether a flush or recessed floor outlet suits the space best. Finally, choose a finish that complements the environment, such as brass, stainless steel, or black nickel.
