Both floors are real oak underfoot, and once fitted most people cannot tell them apart. The difference is in how each one copes with moisture, heat and the subfloor beneath it, and in a coastal parish like St Brelade those three things usually decide the matter for you.
Solid oak is one piece of timber all the way through, usually 18 to 20mm thick. Engineered oak has a top layer of real oak, typically 3 to 6mm, bonded to a plywood or multi-layer core, giving a board of 14 to 20mm overall.
That layered core is the whole point. Oak swells across its width as it takes on moisture and shrinks as it dries. Cross-bonded layers resist that movement, so an engineered board stays much flatter and tighter through the year. Solid oak moves more, which means wider seasonal gaps and a greater risk of cupping if conditions are wrong.
Homes around St Aubin, Ouaisné, La Moye and Corbière sit in salt-laden, humid air for much of the year, then get dried out by central heating in winter. That swing is harder on a timber floor than steady damp or steady dryness.
The building type matters just as much. Many of the bungalows and newer houses around Les Quennevais and Red Houses have concrete slab floors, often with underfloor heating. Older granite cottages tend to have suspended timber joists, sometimes with limited ventilation below.
The usual argument for solid oak is that it can be sanded many times. That is true, but a full sand removes roughly 0.5 to 1mm, and most households only refinish every 10 to 15 years. An engineered board with a 4 to 6mm wear layer will take three to five sands, which is several decades of use. A thin 2 to 3mm wear layer is where engineered boards earn a poor reputation, so check that figure before anything else.
Engineered boards also come in wider widths, 190 to 240mm and beyond, without the stability problems wide solid boards have. If you want long, wide planks or herringbone over a slab, engineered is the practical route.
Everything arrives by sea, so freight and 5% GST are part of any island price. As a rough guide, good engineered oak is around £50 to £100 per square metre for the boards, and solid oak around £60 to £120. Fitting commonly adds £30 to £55 per square metre, depending on the pattern, the subfloor preparation and how much furniture, skirting and door trimming is involved.
Solid oak rarely costs more because of the timber alone. It costs more because of the time: boards should acclimatise in the room for one to two weeks, and the subfloor often needs more preparation. Levelling a slab or adding a damp proof membrane can shift a quote more than the choice of board.
Whichever you choose, most failures come from moisture that was never measured. A new screed needs roughly one day of drying per millimetre of depth for the first 50mm, and longer beyond that, so a 75mm screed can take three months or more. It should read below 75% relative humidity before timber goes down.
Ask your fitter to test the subfloor, leave a 10 to 15mm expansion gap around the perimeter hidden under skirting, and run underfloor heating up gradually before and after fitting. Those steps matter more than the label on the pack.
Yes. The surface you see and walk on is solid oak, usually 3 to 6mm thick, bonded to a stable plywood or layered timber core. It is not laminate, which is a printed image on fibreboard.
You can, provided it goes over a dry, well ventilated timber subfloor and is properly acclimatised first. Expect more seasonal movement and small gaps in winter than you would see with engineered boards.
Engineered oak. Solid oak dries and shrinks unevenly over a heated floor, which leads to gapping and cupping, and most manufacturers will not guarantee it for that use.
