Blueline completed the work to the exact high standard i was hoping for, while remaining on budget and estimated timescales - the three things that were most important to us! They were punctual, practical, knowledgeable and willing to give advice when either needed or when something could potentially be improved. They were always available to talk through what was happening at every stage of our job, with any complications arising, and importantly solutions to any problems. They knew their stuff and got the job done without any hassle either. They even came back after the job was finished to shift some pipework which i had an extra requirement for. The best feedback i could give is that we will go straight to them for any work we require in the future, and have already recommended them to friends.

Conversions - General- 11 Oct 2022
We've been seriously impressed with Pawel and his team. They opened up our rear dining room/kitchen wall using an RSJ, following our engineer's drawings perfectly. They also did a few bits of plumbing and bricked up one of the windows at the rear, which is where the new kitchen will be fitted. They were incredibly tidy and really pleasant and courteous to be around, which my wife was so grateful for given we live in a busy family house (most builders are not like this...), I can't thank them enough! We will definitely be using them again in the not-so-distant future!

Florin extended and completely refurbished our 4-bedroom semi-detached house. This included extensive steelwork, underfloor heating, complete re-plumbing and rewiring, excavation, and an entirely new slate roof as well as varying extensions up to three floors high. I cannot say enough good things about his workmanship, professionalism and reliability. His workmanship makes a perfectionist like myself happy. He is also completely professional: even with our difficult neighbours he was always courteous and understanding, and even helped them sort out issues at a moment’s notice that had nothing to do with his building work on our property. And he is also thoroughly reliable. I cannot think of any instance where he committed to something and did not deliver — he even managed to finish all the work on our house ahead of schedule and on budget. We have been so happy with his work that we contracted him to build us a summer house as well, from scratch, and to complete revamping our front garden including elements of hard landscaping. Again he delivered flawlessly and we are very happy with the result. We also continually receive positive comments from people passing by and just seeing the front garden. We have used several other builders in the past on other properties, including far more expensive ones, and none compare to his level of competence, attention to detail in his workmanship, his complete professionalism and thorough reliability. Now that we have found Florin, we will never look for another builder again. I just hope once others experience what he delivers for themselves he will still have some availability for us in the future!

Loft Conversion- 18 Sep 2024
He acted fraudulent and without due care and professionalism. Shortly after commencing the project, he came up with variations, denying several things were not included in quote when we asked for a complete quote for refurbishment. He then started cutting corners and did terrible unethical things which of course building controls refused to sign off and ran off with money paid to him then started threatening me which of course I had to report and document with the police. I had to correct what he did at great cost to me and waited this long just to complete the project first before taking up this matter. I kept all the records carefully and plan to sue. I recommend to stay away from Prep, his company, structural engineer etc.

Carpentry- 13 Aug 2026
Alex did what I asked and did a great job installing the awning. He also installed a metal shed and put up a beam to cover part of a wall. Overall, the work was good, although a few small details were missed in the shed, which seemed to be due to a lack of attention to detail. I found the price a little expensive, but overall I’m happy

Restoration & Refurbishment- 19 Apr 2025
Positively, certain aspects of the finishing, particularly tiling, were carried out to a good standard. However, the overall experience was mixed due to significant issues. There were notable challenges during the project involving basic logistics and site management, leading to considerable inconvenience that seemed avoidable. Furthermore, the quality of workmanship was inconsistent; while some parts were good, other areas involving fittings and fixtures showed a lack of attention to detail in the finish, requiring later adjustments. Communication during the process could also be difficult, particularly regarding problem-solving and planning for materials. While we appreciated the parts done well, the project was let down by these inconsistencies and process issues, leading to some ongoing snagging and disappointment.

Extensions- 8 Oct 2018
Alton and his team at Bluelime have been incredibly helpful and enthusiastic throughout our design and planning process. From the start, Alton took his time to understand our needs and propose several cost-effective ways to improve my home and create more space for my growing family. The design process was completed efficiently and submitted for planning permission, which was granted without a problem. Since then, his team have continued to be helpful and communicative despite my need to delay to the building works due to unfortunate complications with my freeholder.

Plastering- 17 Jun 2024
Adam Favor and NOVA Design & Build are a nice bunch of guys and they are reliable/helpful. However, when it came to coving, architrave and flooring, acceptable standards were unfortunately not met. Other specialists had to be brought in to re-do around 20% of the job; namely certain sections of the cornice and door architrave. In the former, a few things were below standard including: 1) not joining the friezes in the correct places, 2) cutting inaccurately, 3) leaving gaps, 4) using silicon as a filler and adhesive. For the door architrave, the wood was misaligned and not glued/nailed properly. The flooring was not laid well because there are huge gaps at times; sometimes at 1 cm. Since the kitchen has been installed, it is too late to take up the floorboards again. The most dubious thing of all in this job was the quote received for decorating which was c. 15k for 47 m2. This included plastering repairs, but ultimately the job got done by someone else to a high standard at 7k.

Restoration & Refurbishment- 28 Apr 2024
I highly recommend these people if you want to be fleeced, taken advantage of, treated appallingly and work left unfinished. The standard of work is below average. If you want high quality finishing do not come here. I’ve had to spend a lot to redo a lot of their mistakes and mess. If Jerzy could charge you for every single nail he would, so beware. And when you challenge, they get aggressive and nasty. Very unprofessional. Do yourself a favour and keep away. So thanks Jerzy and co for a load of stress and rubbish. I am happy to talk to anyone and advise against these people.

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.
