Plastering- 23 Dec 2016
Denis did a good job plastering and retiling a small area of my kitchen. He responded to my ad promtly, came round the next day to quote and carried out the work 2 days later as requested. He was professional, polite and left my kitchen clean and tidy after the work was done. I'm happy to recommend him and would contact him again if needs be.

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.

Windows & Doors (Wooden)- 20 Sep 2026
Very disappointed with the workmanship. The finishing was poor and several parts of the job needed to be corrected. I expected much better quality for the price.

Extensions- 25 Apr 2020
Financial restrictions meant we had to change from an extension to simply improving the existing house. I gave Vlad a call on a friday and his army was ready to start the very next Monday morning. All would have been finished in less than 2 weeks but the unexpected Covid-19 lockdown on 23rd March meant that supplies were harder to get. Very pleased with our brand new house. Good job done on new Electrics, Kitchen, Bathroom and plumbing and he even helped fix our D.I.Y furniture at the end. Will definitely use VM on our next project.
