How much should it cost (very roughly) to get someone to floorboard a loft (UK)?

My brother did a DIY flooring job on his dining room recently, and materials (wood, insulation and nails) cost him £250-300.

You probably ought to consider fitting a loft ladder for future access - these start at about £50 depending on length, number of sections, materials and strength. You may need to modify the access hatch as a fitted ladder will need a hatch that hinges downwards. The size of the opening may need to be increased depending on how big it is now and how easy it is for you to get through without bashing your head. Minimum 500mm wide by 1200mm.

For the flooring you could buy sheets of 18mm chipboard 1220 x 2440 at about £10 a piece but these will have to be cut down to a size that will fit through the hatch. Better to use chipboard loft boards which are about 1220 x 330 at about £5.00 per pack of three boards (so do not need sawing) and have interlocking edges which make a stronger floor.

Finally if you pay for the heating in the rooms below you should add loft insulation before putting the flooring down. Typically the ceiling joists are only 100mm deep so ordinary fibreglass insulation will not really be sufficient (you should have 270mm of this) but is better than nothing. Using high performance rigid insulation will push the costs up considerably.

And then there is the lighting that you will need both for working and if you plan to use the space frequently when it is boarded.

Labour - at least a days work to insulate and board a decent area; more if the hatch needs enlarging.

Good luck

I was thinking around £200 but as you have few details Id quote £300

Well , you could hire a gentleman from the states and give him room and board for the duration of the job. He has never been to England. A working vacation if you will........

if you have no access how can someone give you a quote?.you can get loft boards from b+q/wickes etc.a weekend of d.i.y is in order i think.
