Hi Dave
Glyfos for sure.

Gallup 360, used it to kill grass loads of times
another here for gallop 360, use it on grass around fences/trees all the time
Thanks guys, two votes for Gallup so will try this. Do you know if it's okay to lay new turf on the area a couple of weeks later? It doesn't leave too much residual toxin does it?
Hi Dave,
You need to be careful - while the effects/ residues of glyphosate are normally all but gone within two days in SOIL, if you plan to sprayoff a lawn and turf straight over it - the glyphosate can be held in the dying grass/ foliage for a lot longer - Roundup advise turning the soil for safety then laying new turf/ seeding.
Also in colder weather microbial soil activity will be slower so it will not breakdown as quickly.
Check the label as Gallup, like Roundup, comes in a number of variations. Here to help if you need - Gallup or other brands.....

Great advice, thank you again. One last question... Are the clients pets safe using this stuff? Do I need to tell them to keep them indoors for a time? Definitely don't want to be responsible for killing the family pet!
Yes, general advice is keep pets, children and other animals..(!)... off, until spray has dried. Grazing animals are different but I am guessing there are no cows, horses etc present in the back garden...
If in doubt check the label
The merest drift of Roundup will kill grass, so I'm not sure why it hasn't worked for you Dave. Maybe it rained soon after or it was cold and the grass wasn't growing, in which case, it takes time.
Anyway, we have approached this sort of job many, many times and depending on the budget, tackled it both ways. The best? Spray, clean off turf, rotorvate and prep. Next best - spray, strim off grass to soil(mind the windows!) rotorvate and prep. Do not lay grass on grass, unless the client is looking to save the £££'s - but even then I would be thinking of my reputation and give it a miss.
if we are laying a new lawn we very rarely spray it with weedkiller, unless the lawn is bad. we always lay a loam soil over the top of the rotovated soil and I don't see there is any need for the weedkiller. when its been properly rotovated and any weeds are picked out, its absolutely fine and it cuts down on the use of chemicals. the grass rotovated in is good for the soil as well
