UKPC Construction is by far the best company I have ever worked with, and I highly recommend them to anyone. Their team is not only courteous and professional but also a breeze to work with. They expertly helped me transform my jungle-like garden, and although I'm writing this review after some time, I'm now looking forward to discussing the extension project they initially designed with me. A big thank you to UKPCC, and I wholeheartedly endorse their services to everyone.

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

Extension Builder in Sidcup
Hello, my name is Henry, I am a 25 year old bricklayer from South east London. I wanted to become a bricklayer after learning of the history behind the bricklaying, particularly Victorian bricklayers. I often look at old buildings and think of what an honor it would be for future generations to look at my work in years to come and be proud of their ancestors' craftmanship, built with care and attention to detail that will have withstood the test of time.

Extensions- 15 Dec 2021
Valdemar and his team of workers were outstanding. I have never known builders to be so thorough, honest and just generally nice people. They can be trusted and gave honest opinions. They were in tune with the building control requirements and worked very hard always arriving on time and working solidly throughout the day. They may be a bit pricey but you definitely got what you paid for - First class workmen ship.
