Extensions- 28 Oct 2018
We appointed HWB to carry out a full refurbishment on our house, this involved re-gutting the interior and building an extension and loft conversion plus some landscaping in the garden. We spoke to many builders but finally appointed HWB based on their previous projects and professionalism. Appointing builders for any work is always difficult however we are delighted that we went with HWB. Throughout the project they have demonstrated high levels of professionalism, were very organised and worked to very high standards. They were collaborative throughout the whole project and kept us informed at every stage. As the project developed there were some changes made and HWB were flexible and open to new instructions made by us, as well as giving us valuable advice. Farag, Ayoub and the HWB team were always available to answer any questions and provided us with constant feedback on progress as well as identify new solutions to aid the development. They have a great team of workers who work to a high standard and are supervised throughout the project. We made the right decision going with HWB Construction and have no hesitation in recommending them.

Landscaping- 2 Oct 2020
From the moment Alex arrived - on time - to quote for the work he was full of energy for the job, interested in what needed doing and had some great ideas. I received a clear, detailed quote and Alex was happy to talk everything through. Alex, Christian and team are skilled workers, polite and tidy. The work was completed to a high standard, on time, and has totally transformed my fenced area and garden - beyond what I had imagined. My neighbours on both sides were so impressed they have also hired We Fix. I would have no hesitation in recommending Alex and his team. A great professional outfit. Thank you We Fix!

Handyman- 6 Jan 2026
Firstly, I havent used mybuilder in years, and I hired Zaim hoping for a good job on our dining chairs. I can safely say I was very suprised. He did an excellent job. From the moment we talked he had great communication, he was timely and said he would call 30 mins before arrival which he did, he spent time fixing the legs of the chairs as if he were doing the work in his own home. He is also not afraid of letting you watch him work, he has nothing to hide and is genuinely a nice person. He wants to do a good job and doesn't leave until the room is in the condition it was in before he came, he even hoovered up afterwards. Zaim was professional, calm and knowledgeable. Some people do a rush job, but you could see he wanted to do a job that was good, even redoing work because he wasn't happy with it. A solid job. Would certainly recommend.

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.
