Hi,We live at the end of a terrace of 4 properties that were built around 1930's and for years we had issues that the drains were getting blocked and were getting expensive to clear each time (the hatches are on our property). I was talking to a colleague at work a few years back who told me that he'd had an identical experience and discovered that Thames Water had an obligation to clear the drains, free of charge, if your property was built within a certain period. Well, we tested this, called the number up and ever since, we have enjoyed an excellent service, free of charge. The number we call is 0845 9200 800. I'm a bit tight for time but if I remember later, I'll serch for the page on the TW website that provides the information...
