I have just been talking to a friend who owns a villa in Calis. She has been asked to pay £3,900 towards the cost of her house connecting to the main drains, there are 10 villas altogether and they are all paying an equal share of the costs. This seems very expensive (almost £40,000 in total) and odd that it's been priced in sterling. Has anyone else had to pay for this service recently and is this an average cost for this type of work? Many thanks in advance for your assistance.
