Bathroom Fitting- 2 Jan 2025
Extremely Disappinted with Planetium Construction- I hired Planetium for a 59k renovation job. Initially, the workmanship was acceptable only because I supervised closely and had them redo substandard work multiple times. However, before the job has been complete, I discovered already a roof leak in the master bedroom, direcly under the newly renovated bathroom. Despite my repeated requests, Planetium refused to take responsiblity or fix the issue. Just telling me need additional charges for the work. Worst still, Adrian the owner, demanded I pay the final balance of 1840 before they would address the GF heating which stopped working after they installed the new controller. When I reasonably refused to pay before they complete the job , Adrian swore at me over the phone the most offensive language. Furthermore, they promised to replace a new Miele microwave for the one they damaged during installation but now just walked away. Leaving me unresolved issues and additional repair cost!

Windows & Doors (uPVC & Metal)- 25 Apr 2026
We found Marian from CM Fixing after the suppliers recommended fitter proved unresponsive and we are so pleased we did. We have found dealing with Marian an absolute pleasure - really responsive communication, excellent price and he has done a fantastic job for us today. They arrived promptly at 8am and fitted our new doors with no fuss and lots of care and it’s all looking amazing. I would recommend Marian and his team to anyone considering an installation.

Architecture- 18 Aug 2025
Despite some initial positives, the project was ultimately marred by poor communication, unprofessional conduct & serious breaches of trust. We strongly advise against using Bluelime due to the stress, financial impact, & unresolved issues we faced. While kitchen & bathroom installations were OK & progressed quickly, Bluelime deviated from approved plans in a conservation area, causing compliance issues (estimated correction costs of £15–£20k). Heating & insulation were poorly installed, & second opinions confirmed our dissatisfaction. Communication broke down, with responses defensive and intimidating. Costs rose unexpectedly (e.g. door fitting from £1200 to £2640) & inflated quotes in later stages. The property wasn’t ready for move-in multiple times, disrupting our young family. Additional concerns included missing tools, ignored warranties, inconsistent workmanship & misleading claims about affiliations. We urge others to check Bluelime (Alton Campbell) on Companies House.

Extensions- 23 Dec 2022
ELB Construction completed some major garden works for me and constructed a garden office. It was a big piece of work with a lot of earth moving, significant foundations and a lot of brickwork. The ELB team, specifically Jimmy the site manager, were fantastic, always giving me the right advice about things I was not knowledgeable about, always focussed on a quality finish and flexible when we had some challenges with our neighbours. The finish is great, communication was always open and honest and they were very competitively priced. My brother in law is in corporate construction and was specifically very impressed with the quality of the brickwork that Jimmy and the team produced. Thank you to the whole team!

Extensions- 8 Dec 2017
We couldn’t be happier with the professionalism and quality of workmanship from REA Construction. The project was delivered within budget and on time. We lived in the property during the work and we, our neighbours and the site were always treated with the utmost consideration. There were almost no hitches and, when they did occur, they were dealt with immediately and thoroughly. Our project team, led by Kristjan and Besi, were universally hardworking, organised and produced work to an excellent standard. Communication is great, the people are wonderful. Renato was someone I felt I could trust from the moment I met him and he never let us down. He and everyone at REA genuinely care about what they do and that their customers have a happy experience. We certainly did and would have no hesitation recommending them to others.
