To clarify the following prices it is recommended that you read the article in the BLUE BOX below

Cost to Board a Loft/Attic

These prices are based on a tradesman’s rate of £150 per day and a labourer if required at £100 per day. They include the cost of buying and collecting any materials, dumping any waste if necessary and any incidental materials they will need.

(The minimum price will usually be for a half day)


Job 1
Screw down half a dozen chipboard sections over a supporting wall (this will give you more than 8.5 m² of boarding)….1 man, half a day plus the boards…………£125.00


Job 2
Job 1 but with 75 mm thick rigid insulation boards underneath (3 @ £23 each). This will still take only half a day………….£200.00


Job 3
Board out the whole loft with chipboard. (definitely not recommended). This will take 2 men I day plus £230 for materials ………..£480.00

Job 4
Job 3 with the same insulation underneath. This will take 2 men 1.5 days…..£935.00

Material Information

18mm Tongued and Grooved Chipboard Sheets £5.00 per square metre

Don’t do it. All you’ll do is fill the loft with stuff that you will never see or use again, that you’ll only have to shift when you move house next, or your kids will chuck away when you shuffle off this mortal coil!

Fill the loft with insulation instead! You’re not listening are you? Ok, ruin you ceilings, it’s not our problem.

Actually, ruining your ceilings will be a problem if you store too much stuff and/or store it in the wrong place. Ceilings were only designed to support themselves, not half a ton of nostalgia.

Loft boarding is usually done with 8’ long x 2’ wide, interlocking chipboard sections. If you are clever, you can have these arranged so that they span a bedroom or landing wall below. This will then carry a lot of the weight of the boxes you are going to put on them and not the ceiling joists.

Now there’s another problem; what about the insulation? The more boards you have, the less insulation you can lay, therefore more heat you waste. This can be overcome by laying insulation level with the tops of the relevant joists. (You probably have it there already). Rigid insulation boards (Celotex, Kingspan) are then fixed across the joists and these are then covered with the chipboard.

Insulation boards come in thicknesses up to 120mm (£35) and will probably have to be cut in half to get them in the loft. The chipboard sections cost about £8 each.
