Landscaping- 26 Jul 2026
AVOID. What was quoted as a simple 12-day project turned into a multi-month ordeal requiring constant chasing, while he pressured me to pay 80% upfront for barely 20% of the work completed. Unreliable: - Never stuck to agreed schedules; showed up at random times for a few hours or not at all. - Left materials dumped on the public pavement and communal garden, causing a nuisance. - Required me to personally manage and receive material deliveries. - Left pile-ups of rubbish in communal areas, which he only cleaned up after I refused to release final payment until it was cleared. Substandard work: - fence slats were noticeably warped from Day 1. - tiles thinner than specified in the original quote. - agreed raised flower bed never built. - custom built-in storage unit leaks, interior completely rotten and covered in mold just weeks after completion. - he made false promises that he would come back to inspect and fix his defective work to completely disappear

Carpentry- 19 Sep 2015
Not only was Ian's quote to do the loft conversion very reasonable, he was very reliable, tidy & very helpful when we had a difficult situation. The work was done in a quick time, when he said he was going to be on site he was, at no time did he let me down. The standard of work was excellent, I would recommend Ian & wouldn't hesitate to use him in the future.

I highly recommend William Haykal. We hired him to renovate our entire 2 bedroom, 2 bathrooms flat, he’s done the job in just 19 days and the end result is simply stunning. His attention to details, craftsmanship, and professionalism exceeded my expectations. From the initial consultation to the final touches, he made the process seamless and delivered outstanding results. I couldn't be happier with his work!
