Highlights
"Greece came to unblock our sewage drain, he came promptly and unblocked the drain, he gave valuable advice too, thank you. He is definitely a number to keep if having drain problems."
"Reece was great, was able to come within the hour. We were a bit worried as we had a dip in our paving and thought it would be a collaspsed drain pipe. Reece explained to us it wasn't as bad as that. He knew what he was doing and knew the source of the blockage. Reece was also competitively priced. Would definitely recommend."

Now trading as HBDRAINAGE LTD. Reece failed to turn up multiple times. Poor workmanship. Missed important things like a cracked drain. Didn't provide everything we paid for. Blatently lied about installing two patch liners (a third party plumber confirmed that none were installed). Refused to refund so we're having to take him to court now. At the time of writing his filings with Companies House are overdue and Reece is director of a relatively new company named BROMLEY DRAINAGE CO LTD. Smells like phoenixing to me. Do not trust this guy.
