Insulation for the attic

Hi folks
Want to sort out the insulation in our attic, and have been given two qoutes.
One is to insulate between the joists, the second is for insulating between the rafters.
Is there any significant difference between the two, in terms of how well they insulate along with the pro's and con's of each, as the joist quote is circa £350, and the rafter qoute £230.
many thanks

Hi
What kind of insulation and how much of it?

By this do they mean insulating on the back of the ceiling or on the underside of the roof. If you insulate on the underside of the roof and create a warm roof then you are paying to heat that unusable space. Unless you specifically need to insulate the roof I would insulate on the back of the ceiling.I have a lot of problems with my neighbours, they hammer and bang on the walls sometimes until 2 or 3 in the morning - some nights I can hardly hear myself drilling

The only advantage i can see in insulating the roof, and letting some heat into an empty loft would be if you have any pipes up there, there is less chance they will freeze.
But better to insulate the floor of the loft and then insulate any exposed pipes.Liverpool is one of the wonders of Britain,

To clarify - between the joists on the floor of the attic, and between the rafters on the inside of the roof.
As it's a Victorian house, the floor joist are an uneven height, so i know i'll have to do some battening to be able to put some flooring above the insulation.
Would putting thermal plaster-board on the ceilings of the rooms directly under the attic floor be as useful as loft insulation ?
Just trying to find out the best/easiest/most cost effective option !
Plus, not looking forward to getting all our stuff out of the attic !!Baby-Mechanic

I just had Tri-Iso Multifoil insulation fixed to underside of roof rafters, using staples and actis tape, sealing all open edges of multifoil insulation. After multifoil fixed to underside of rafters, tape together all overlaps and finsh eaves with mineral wool, to provide sealed area in loft. Edwardian 2 bed house and paid £1,547.67. I thought it was a bit on the expensive side but he said the materials are expensive.0
