I have also had a similar scary incident with Anglian Home Improvements. I cancelled my Anglian window contract on day 8 after being assured by the salesman that all I would lose would be my £50 deposit. Within 3 days of cancelling I received a very terse letter headed in block capitals BREACH OF CONTRACT, and telling me I was liable to pay up to 80% of the contract price. Of course this is rubbish at such an early stage of cancellation, but the only thing in black and white is that after 7 days you are liable to pay 25%; in my case over £2000. There is no mention of only losing your £50 deposit. Frankly I was panicked and stressed by this. All I had was a verbal agreement by the salesman about only losing the £50. You are asked to call a regional sales rep, who is clearly there to try to do you a better deal...to play nice cop to the nasty cop of the letter. I told him about what the salesman told me. After checking he phoned back to say that yes, all I would lose was my £50 as I had cancelled after the 7 day cooling off period and then went on to offer me a better deal on the windows on which I could reclaim my £50. My advice. If you want to cancel make sure you do so within seven days IN WRITING, a phone call will not do. When you arrange to see the salesman tell him in advance of his visit that you have no intention of signing the contract on that day but want to keep it at home to think about it. That way he knows in advance not to try pressure selling as you can rebut him with the statement that you had already told him that you were not prepared to sign on that day. Take notes on what the salesman tells you. If it contradicts what it says in the contract about liability for cancellation charges or anything else, write or e-mail him to ask him to tell you in writing what he told you. I have no idea what the Anglian product is like. But their standard cancellation letter is bullying and perhaps meant to intimidate people into being bounced into a purchase they might not otherwise want. it leaves a bad taste in the mouth and because of this I would not recommend dealing with Anglian Home Improvements. But on the 25%...hold your nerve and don't be intimidated.
