Most office fit-outs in Tiverton and across Mid Devon come down to one early decision: drop a suspended grid in, or board and skim the underside. It sounds like a finish choice, but it quietly sets your budget, your maintenance costs and how easily you can move a light or a smoke detector in three years' time. Here is the honest comparison, without the sales patter.
A suspended ceiling (properly, a modular grid) hangs on wires or angle from the soffit above, forming a T-bar lattice that holds removable tiles, typically 600 x 600mm or 1200 x 600mm. Everything above it stays reachable: lift a tile with two fingers and you are in the void.
A plasterboard ceiling is a fixed MF or timber-batten frame with boards screwed to it, taped and jointed or skimmed to a flat, seamless plane. Access happens only where you build it in, via hatches. It reads as architecture rather than as a system, which is why it suits reception areas, boardrooms and converted period buildings around Tiverton town centre where a grid would look wrong against original cornice or beams.
As a rough guide for commercial work in Devon, a straightforward suspended grid with standard mineral tiles tends to land somewhere around 25 to 45 pounds per square metre supplied and fitted, with acoustic or hygiene tiles pushing higher. Plasterboard on MF is usually a bit more, often 40 to 70 pounds per square metre once taping, skimming and decoration are included, more again for bulkheads, shadow gaps or curves.
Those are starting points, not quotes. Height of the soffit, the state of the existing structure, asbestos surveys in anything pre-2000, fire rating requirements and whether you need out-of-hours working all move the figure. The larger hidden cost is usually the follow-on trades: a grid lets the electricians and mechanical fitters work quickly above the line, whereas plasterboard needs everything first fixed, tested and signed off before boarding starts, because opening it up later means making good and redecorating.
If your office ceiling void carries VRF pipework, sprinkler heads, cabling for hot-desking or anything likely to change with the next tenant, a grid pays for itself. Landlords letting units on the industrial estates around Tiverton often specify grid for exactly this reason: dilapidations at lease end are cheaper when tiles can be swapped rather than patched.
On sound, do not assume the grid wins. A mineral tile with a decent absorption rating does help control reverberation in an open-plan space, and that is where plasterboard needs help from rafts, baffles or perforated board. But for stopping sound passing between two adjoining offices, plasterboard with a proper head detail and insulation in the void usually outperforms a grid, because a continuous void above a grid lets speech flank straight over the partition. If confidentiality matters, in an HR office or a consulting room, take the partition to the soffit whichever ceiling you choose.
A grid goes up fast. On a typical 200 square metre office you might be looking at a few days for the grid and tiling once the perimeter is set out, and it can often be installed in phases so half the floor keeps trading. Plasterboard is slower: framing, boarding, taping or skimming, drying time, then decoration. Allow a week and a half to two weeks for the same area, and accept that the space is genuinely out of use while it dries.
For occupied offices we would usually suggest sequencing the work by zone and being realistic about dust. Skimming brings moisture and mess that laptops and paperwork do not enjoy. If you cannot vacate, a grid is the kinder option.
Yes, and it is often the best answer. Plasterboard the reception, meeting rooms and corridors where the finish is seen, and use a grid over open-plan desking and anywhere with dense services above.
It costs you roughly 150 to 400mm of height depending on the depth of light fittings and services above. If your soffit is under about 2.6m, look at slimmer fittings or a plasterboard ceiling fixed tight to the structure.
The ceiling itself rarely needs approval on its own, but fire compartmentation, means of escape and any change of use do. If you are altering a fire-rated ceiling or subdividing a space, speak to building control before work starts.
