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.

Extensions- 7 Jun 2026
Zilvinas and the team at Innovate Builders were outstanding from start to finish. We hired them to build our two-storey side extension. Zilvinas was open, professional, and fully committed throughout the project. He was always available to answer questions, offer advice, and guide us through each stage of the build. His team worked hard and delivered a high-quality finish, all while keeping the project on schedule and within budget. As this was our first major building project, we relied heavily on Zilvinas's expertise and guidance. His knowledge, practical advice, and problem-solving skills were invaluable and made what could have been a stressful experience feel smooth and manageable. We are absolutely delighted with the result and would not hesitate to recommend Innovate Builder. As I said it was our first ever big project, we had heard many horror stories but are so grateful to have found Zilvinas and his team.
