Do not use this company! The engineers will work slow, and stall the job in order to charge you more... An engineer came to switch an oven over. He was painfully slow, walking back and forth to the gas meter like a snail. The job was done in about 40 minutes (and quite honestly could have been done in much less) but he filled out the paperwork after so slowly and stood there on his phone in my kitchen for about 15-20 minutes. Since the company charge you £50 for half an hour, I realised what he was doing and asked why he was standing there. So when he thought enough time had gone past the hour (around 10 mins), of course he announced he was charging for an extra half hour (so total £150). Shocking! And in this time, he'd drunk a cup of tea I made him. Despite this, the company continued to take £150 from my account without my approval and have ignored all my requests by email and telephone to give me back my £50. I've never felt so angry at a company! Utter day light robbery. I will never be using Aspect again and will advise you not to as well. Most expensive cup of tea I ever made...
