very soggy garden

If the drainage is that bad, one option would be land drains or a soakaway, but you need to have a dig down in a few spots and see what you have.

There are some gardens around the Reading area where there is a heavy and solid layer of blue clay under the surface.  The only option in those is to dig it out and replace with decent top soil   

A lot depends what the soil is like a few feet down. We had really solid clay in Crewe. I dug holes where the puddles were and put a mix of gravel and broken tiles from the kitchen refurb in before re-filling with decent soil. Along the border, which was the wettest bit, I trenched and re-filled the same way.

Land drains and proper soakaways are a lot of work but the half job sorted the problem.

I don't know how big your garden is but willows do well in wet soil and their roots soak up a lot.

Your neighbour's slabs just push the water to another spot and gravel allows it through too quickly. Don't under-estimate the power of grass roots to soak up and slow water.

Incidentally, where we are now in Wales, we had a rainstorm (so unusual in Wales to have rain ) and even the land drain installed behind the cowsheds was overwhelmed. I'm now planting banks of trees uphill to help with wind mainly but also water.

Ive been digging through my compost bins and there is a massive lump of worms in the middle and my thought were could i take some of these worms and sprinkle them over my heavy soil and grass area would they improve my soil over time and if so could i do this before it gets too cold and not to sure if the soil would be to heavy going for them.

Worms are great but they need organic matter to live on so they're unlikely to do well on heavy, compact clay where there is no food for them.

For a lawn where the soil is compacted underneath the best answer is to use a hollow tine fork and brush coarse sand into the holes. Unless you're willing to dig it all up and start again

Woodchip does rot down to a nice humus but is hardly nutrient rich! It absorbs nitrogen in the early stages as well. That's why I use it for paths, it suppresses growth and eventually is dug in to improve soil.

Im not up on what worms they are but they have made me some good compost and the clump is bigger than a foot ball the thing is imnot going to be living in the house for a few years so i wont be able to keep tabs on it and dont have time to do anything that will take too much time , i will just keep going over with a fork till i get a tennant in there , thanks for the help i will keep it in mind.
