Insulating under stairs meter cupboard..

We have a problem with draughts coming up through the stairs, from our externally accessed meter cupboard situated under the staircase. We've tried putting up insulation boards, but due to the angle (and gravity!) it's not ideal, as they fall down and it isn't draught free. We've been looking at spray foam insulation as a solution. Any thoughts, or recommendations of products and companies who will install it gratefully received.

cut the insulation boards to fit under each step allow overhang for the riser part and either silicone or expanding foam them to the underside of the steps

hi i would either put some slate lath over the stairs then screw the insulation to the slate lath . use screws with a large heads so it doesn,t pop off easy . good luck ta jeff

this could work aswell ta jeff

Loft insulation, held up with chicken wire stapled to the stairs (if exposed), or as Jeff suggests screw some laths up first (using screws that don't pop thro and cripple you on the other side !!)

Also, can you provide evidence to show you supply "the best" contractually binding quotes ? Or is this just a meaningless and misleading throwaway statement ?
