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.

Conversions - General- 8 Dec 2021
We are very happy with Zaza and his team's work on our flat, which included taking down a structural wall and installing a box frame to support the load, and then installing a new kitchen, toilet, floors and wardrobes. They worked diligently and efficiently, and managed to work around supply problems, as well as the challenges of us living in the flat during the works, to ensure the project finished on time and on budget. They communicated well, making sure to understand exactly what we wanted to do while also giving good advice where compromises had to be made, and gave us frequent updates on the progress of the work. We will definitely want to work with them again on our next project!

Cocis Construction Group done the full interior painting of our 5 bedroom house and we are really happy with the result. The team was polite and worked very hard every day. They kept things clean and finished everything on time like they said they would. The paint finish looks great and the whole house feels fresh again. Would definitely recommend them if you need painting done.

Conversions - General- 7 Feb 2022
DBM Contractors have been excellent! Having moved home, had structural work and general renovations done 3 times in the last 10 years, Orgest and his team have been by far the best we’ve experienced and we certainly will not look anywhere else in future. Once we agreed on the schedule of works and price, during which time the communication was polite, clear and consistent, there was a plan set out and the timeline to start work was precise and adhered to. He deployed the right number of people from day 1 - they work at speed but with clear quality and without shortcuts. As a result, we were further along than we expected within the first few days alone. Naturally, we added some work along the way - the communication around this was clear and we felt like we were involved in every step. They shared the smallest of details during the job so that the decision making was a combined effort. The level of communication, politeness, general friendliness and openness to help from the whole team has been very good. As we’re waiting for better weather, all but 1 job has been completed and we are very happy with the finished product – we wholeheartedly recommend DBM contractors for any work you are considering.

Extensions- 20 Feb 2020
Decent builders but with extremely poor communication skills. First the good points: 1. They are good at internal finishes 2. They create and use a Statement of Work (SOW) to track all costs of the project, so there were no major surprises in the project 3. They are friendly and hard workers - who arrive on time Gotbath UK Ltd used subcontractors to build us a 6 meter rear extension. Although they had an in-house architect, they did not know the law around boundaries which resulted in a conflict with our neighbours. After spending hundreds on hiring a boundary surveyor, the initial wall had to be re-built within our boundary. Gotbath did not take any responsibility for the wrong information they provided to us regarding boundaries and charged us for the rebuild. When discussing how to finish the inside of the extension, GotBath were extremely slow in ordering supplies and in general responding to us, so we took matters into our own hands and ordered materials ourselves which were removed from the SOW provided to us. At the end of the project, finishes took a long time and required constant chasing. Final gas, electrical and warranty documents took a long time to reach us and required a lot of chasing too. I have very little confidence that GotBath will honour the warranty document they have provided to us. It's a shame because I can see GotBath have a lot of potential as a builder. However, their lack of communication has really let them down.

Conversions - General- 30 Jul 2019
offered me useful advice related to the structural framework of my bay window which was in question as it had moved away from the building ever so slightly. Very responsive and communicated well which is what you want from a tradesman. I asked for additional work to be carried out that included sealing bathroom worktop, sanding down and improving the surface together with cutting out a peice of wood to make my boiler more accessible. This was completed to a neutral standard as the finish I was expecting was to be better with a cleaner finish also. Overall the job was positive, thank you very much.
