Sandeep was very punctual, good communicator and did a nice job. I was pleased with the work and the quote was fairly priced, after some outrageous quotes I got from others. I would recommend Sandeep in the future.

Kenny and team did a brilliant job replacing my old lean-to porch area for a new smart extension with windows, door and even a cat flap. They were on time, organised, efficient and took away all the old materials and rubbish. Kenny was helpful when he visited and prompt in replying to all communications and supplying quotes and invoices. I am very happy with their work and wouldn't hesitate to recommend their services.

Home Utility Ltd recently carried out a complete renovation of my 4-bedroom house, and the quality of their work is outstanding. From fitting a brand-new kitchen to completely transforming the bathrooms, every aspect of the makeover was handled with great attention to detail. The team was reliable, highly skilled, and managed the entire project seamlessly from start to finish. Finding a contractor that delivers on every promise without hassle is rare, but Home Utility Ltd made the entire process smooth and stress-free. If you are looking for a trustworthy team to handle a major home renovation, I cannot recommend them enough.

Extensions- 29 Jan 2015
PM Building epitomise what a modern day, professional building firm should aspire to be. Transparent pricing, a friendly team working 6, sometimes 7 days a week to get the job done quickly, an eye for detail and very high standard of final finish. All comms and the overall work is run through Bart, who answers to phone, text or email quickly and frequently outside normal working hours. This is ideal if you work during the day and cannot be around to oversee things directly. We also got PM Building to make us a bespoke kitchen, again very high quality and millimetre perfect. If I had to find some negatives, they are not the cheapest company you could find, but there again you get what you pay for; also, we developed a few issues with some retaining walls in the garden, however, they returned when I contacted them long after the work had finished and fixed them! All in all, an excellent, honest and professional company to deal with. I would, and have, recommended them to friends...nuff said.

Extensions- 19 Aug 2026
We paid for the build finished in Sept. 2025. Our concern is the foundations. The drawings specified about 1.8m depth and anti-heave boards due to clay and trees. The builder had not properly checked the drawings, then charged substantial extra for the depth. We paid, but the boards were not installed, and our photos and videos appear to show much of the foundation at about 1m. A replacement Building Controller declined to proceed without evidence of the boards. The patio, including £1,700 extension, was laid without proper excavation or a mechanically compacted base. Some tiles are loose and render is failing. Other faults include uneven floors and walls, falling plaster, catching doors, cladding gaps, poor electrical fitting, missing vents, a possible leak and unfinished items. Attendance was intermittent—about three weeks over two months—and the work felt rushed around other jobs. Our neighbour witnessed two workers urinating behind the shed. We cannot recommend this company...

Restoration & Refurbishment- 19 Nov 2019
Iljaz and his Team were brilliant! I was slightly concerned having no reviews. They found the leak, fixed it and patched up the wall in very tidy and professional manner. He did say he wouldn't be able to come today and updated me, however he made time to come in-between his day to sort out my issue. Not many true trades people like this and very honest and stuck to his word. I would definitely recommend him and would not hesitate to use his team again. Thank Iljaz!

Bricklaying- 24 Apr 2019
Jake and Harry did an amazing job with our front wall and fence in the rear garden. We got three quotes for the job and they were the cheapest but also came across professionally. It wasn't a straight forward job, it was was using reclaimed materials that were varying size and shapes. I was also quite particular on the look, I wanted the brickwork to match our house, they took care to match the pointing and bricks but offered advice on how we could save money whist still getting the look we wanted. They arrived everyday on time, they were reliable, honest and extremely hardworking. They also kept us in the loop throughout the work making sure we were going to be happy with the end result. I have already recommended them to friends and will use them again for our next project. Thumbs up from us!

Extensions- 15 Aug 2018
100% RECOMMENDED Michelle and her partner measured up and competitively quoted within a short space of time. She was then very patient and supportive when unforeseen planning issues popped up and set the start date back by quite some time. Once building started, all questions were promptly answered by either the site manager or Michelle, both being available at all times. I was away for the duration of most of the job and it was very reassuring to know that I was leaving it all in capable and honest hands. The workers were very proficient and tidied up after themselves at end of each day. They also put in some very long hours at times to hasten the work. I was also impressed by the handling of unexpected problems during the building (mainly invasive tree stumps!). I am absolutely thrilled with the end result. High quality workmanship and a beautiful building which I am sure will last many years. I would certainly recommend them without a doubt.
