hey rob
we usually get about 6-7 full installs a day. these can include repulls ( replacing customers damaged or old and perished external drop cables)
most of the other jobs involve installing tv, tv + telephone or tv telephone and broadband into various rooms in the customers house. some jobs are easier than others depending on what external work through the garden needs doing. so basically get a cable from the access point in the street to the house, putting on a service box and running cables from service box to where sevices needed on the property.
some people have concrete or tarmac drives which we have to disc cut through to get the cable to the property and re cement or tarmac after.
never heard of map before but i work for kelly's who are ok.
ill give u a little tip, when u do start, if they ask u if u want to work for a pay agency, say no and u want to work on P.A.Y.E (pay as u earn) which means ull actually be employed by the company and not an agency
hope this helps
