Our stairlift was installed in May 2012, by Acorn, it should have been £2,200, but they had a sale on, and it cost us £1,800. We had 3 firms around to assess and give us quotes, the first 2 refused immediately to give us a quote, saying our staircase was much too narrow to take a stairlift, but Acorn didn`t hesitate, they said they can fit one anywhere, and the did, in 45 minutes, just 3 days after we ordered. We took out a maintenance contract, £500 for 5 years, we thought it expensive, but changed our minds after the motor went and had to be replaced, the engineer said it would have cost £469 without the contract. It has broken down a couple of times, but they do aim to respond within 24 hours, we did once have to wait till the following day, because it was a bank holiday, and skeleton staff working. All in all, very satisfied.
