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.

Architecture- 4 Jun 2026
I recently worked with this structural calculation engineer for a project that required precise drawings, and I couldn’t be happier with the outcome. The calculations were spot-on, and the drawings were clear and detailed, making the process seamless with my builders. Not only was the quality top-notch, but the pricing was fair and transparent. Communication was excellent throughout, and they delivered on time. Highly recommended!

Bathroom Fitting- 28 May 2025
I am extremely happy with the job Isac has done. We are so very lucky to have found Isac to do our home. At the time of the works we were expecting a baby and Isac worked night and day to make sure our home was ready in time for our sons arrival. Without him we would have been screwed. Isac’s work is extremely professional. He has high standards and is very skilled. He’s honest, direct and respectful. I now consider Isac as a friend. He’s come back a few times since the works to check in and is always on the phone is you have any follow up queries. I would recommend Isac to anyone who has work they needed done. Thank you Isac!!!
