We live in an Edwardian 3 bed semi-detached house in West London. The house we're attached to is owned by a landlord and new tenants moved in over the weekend. The first thing they did was fit a satellite dish at the rear of the house in a very obtrusive position. They are Polish so I presume it is to pick up Polish TV.
All the houses are the same design, 2 storey with a single storey section at the back which contains the kitchen. The kitchens have a chimney stack about 2 feet high to which they have attached a pole about 5 feet high with a fairly standard looking size satellite dish. They've then run serveral heavy duty cables along the roof and in through the kitchen window frame where they've drilled a hole. The satellite dish, pole and cables stand out even more starkly because they are all white and the tiles are black.
Bearing in mind that I don't want to get off on the wrong foot with these people what is the law in this area (which in fairness they may be totally unaware of) ?
