I am thinking of laying a path up to my front door using block paving.There is a slight fall towards the house ,about 40mm over 7 metres,is this a problem?Also can I use a decking board on its edge set in concrete,for the restraining edge,or will it need something more stronger.

don't use a timber edging as it will rot over time.
we tend to lay a path in screed sand mixed with cement as this alleviates the need for a compactor.
why, i hear you say?
a small narrow area such as a path can react in a non-uniform manner, when passed over by a compactor. spread can be a problem and dips can occur, causing a little ponding.
if you do lay the pathway in a 'screed mortar' as opposed to a standard bed of screed sand, then you will be able to haunch the mortar up the sides of the paviors creating a concrete restraint.
if the soil either side of the pathway is a fair bit higher than the path, then you will need to use a raised edging.
40mm fall in 7m is not a lot. lay the starter edge of the path to a line. this way you will have an accurate fall to the path.

just make sure the levels either side of the path will not cause rain water to flow onto the path and onwards.
a friend laid a block patio with a very small fall to the house which in itself was not a problem but the water from the garden surrounding the patio flowed nicely onto the patio ........
