5 storey house full rewire

[dcelectrical]

am just quoting a full rewire of a 5 story town house(7 bedroom) in central london, including all spots and sockets supplied, have done all my calculations but am now panicing slightly on cost, as obviously do not want to quote too little, i sit down and quote each item individually but is there an easier way, am i missing a trick???

sensible answers would be greatly appreciated.

i usually find that working out a price per light and a price per socket and a reasonable length of cable then add up how many add the cost
of the ccu and metre tails work out how long add a day cos i never get that bang on then put in price oh and if your good at your job your worth it dont negotiate your price down make deals that seems to work for me hope it helps

How would you price a 3 bed semi?

You don't say if you're going to run a sub main to the upper floors?
