Williams promised investment and that entry to the pier will still be free. It was put up for sale in March together with the two piers at Blackpool, with a total price tag of £12.6 million.
A listed building, the 2,295ft structure has been described as the finest surviving Victorian pier in the country.
Williams said: “The deal has been completed and this pier is now in local ownership, I feel very privileged to be the owner of this wonderful attraction.
“I went to school in Llandudno and grew up looking at the pier and my dad Billy had always wanted to own it.
“He has passed away but he would be very proud that I have now bought it, my mum is certainly very proud.”
“We will keep investing in the pier to secure it for the future. We have invested £4.5m into the pier, we have to ensure we protect that investment for the future.”
Richard Baldwin, director in Bilfinger GVA’s Retail, Hotels and Leisure team, said: “Llandudno Pier has attracted a large amount of interest since it came on to the market six weeks ago and to complete a sale in such a short timescale is extremely satisfying.
“Offers in excess of the asking price were received, but all parties were in agreement that a sale to Adam Williams was in the best interests of the long-term future of Llandudno Pier.”
