Within 2 hours of phoning Aerial Force the engineer Colin turned up and was very pleasant. He said I needed a new aerial and it would cost £330 plus VAT to replace my present aerial. I said I would not pay that and he then asked what I would pay. I said no more than £220 plus VAT so he made "the phone call to the boss" and the lower price was agreed. Bearing in mind he used the original cabling and original pole and just replaced the aerial it says on the internet the price should be between £80 and £100. On the plus side the problem was fixed the same day and TV now works well. However I will not use this company again as to quote me £330 plus VAT to replace an aerial which costs about £30 is extortionate.
