    Issue speedily resolved and work carried out very efficiently

  • Tap cartridge replaced


    Having originally contacted four companies listed on here, Barnaby was the one who consistently kept in contact trying to get to the bottom of the issue (a high pitched noise whenever water was flowing including from the washing machine and loo). He did so with good humour at all times. It was this level of support, despite the fact it was potentially only a small job, that made me go with Westflow. The work was carried out within the hour by Joe who did a great job with Barnaby checking in while he was onsite.

    Beautifully installed in a neat and tidy manner, not to mention fast! With a team of 3 people they did the job in record time. Very polite, courteous and communicative at all times. Excellent value for money!

  • New Boiler Installation

    10Verified Review

    Westflow replaced my boiler which is in my loft, so not the best location. Cannot fault them on any count, excellent communication, they sent a detailed quote over on headed paper breaking down everything that needed doing, I received confirmation emails of their planned visits and then updates/reminders of arrival times in advance which were all very accurate. I have never known such an organised and reliable service, amazing. Extremely helpful, polite and professional. It was all done within a day with no upheaval, very clean, tidy and respectful of my property. Highly recommended!
