Blocked drains
"This was carried out for my 87yo mother, who lives 200miles from me. Your plumber was fantastic and really put my mother at ease. He was kind, understanding of my mother's vulnerability and highly professional. He went way beyond what might normally be expected. In an age where the elderly can be taken advantage of, I can only highly recommend Happy Drains as top class and value for money. "
Blocked sink
"Excellent service and much better value than the larger firms. Staff were punctual, polite and professional. They made sure the job was successfully completed."
Drain clearance
"Happy Drains responded promptly to my request to unblock a drain. They have done the same for two neighbours now and have been recommended on our local WhatsApp. Came out same day, kept me updated on when they were coming. Good communication and were up front about cost. Cleared the drain, no issues. Payment was quick and easy via an invoice on completion with link in email - I paid via Apple Pay. "

A happy company with great people. Deal with confidence."

No fuss. On time. Job done.
"Very easy to organise the appointment to unblock a drain that we had tried and failed to clear ourselves. They were reasonably priced, stuck to their quote, the engineer was very personable, paid for their own parking and explained the issue! That's all I ask from a service company. Thank you Happy Drains."
