I had two implants done a few years ago and I used https://www.dent1st.co.uk/. They were very good. They had a promotional offer on implants and worked out quite well.
Thank you for your reply I will certainly check them out.
Do you already have a regular dentist? If so they will be able to advise you. If they don't do implants themselves, they will be able to arrange the procedure elsewhere. My dentist doesn't do implants on site, but he booked time at a specialist surgery where he did my implants.
