Hi we have bought a new house in autumn last year. Over the entire autumn and winter we didn't realise that the trees on our neighbours garden are actually blocking any sunlight falling into our garden. We have a conservatory but no light falls into it. They have a row of a 4-5 quite large trees about 10 mtrs high each. Can I legally ask them to cut it down to an acceptable length? We have had a pretty good relationship with them so far, but I'm not sure how to approach this topic. Thanks
