Kitchen Fitting- 18 Nov 2025
Original timeline stretched a bit due to his other jobs but this was fine. Mario started work early and finished early which suited us. He came to visit and we agreed a price at the start and he stuck to it even when he realised some additional plumbing would be needed. He was honest about some accidental damage. Attention to detail is good and he has all the kit. I would have given 5 stars- he's a proper professional and I enjoyed working with him. 3 stars only because as soon as the work was done he became incommunicado (I messaged a week later to ask how to lift door which had dropped down a few mm on fridge). The warranty advertised is one of the reasons I went with MGB which was £200 more expensive than contenders so this was disappointing. I would have asked him to do my parents' new kitchen too otherwise.

What qualifications and experience do you have as an extension builder in South Kensington?

An extension builder in South Kensington should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in South Kensington?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the South Kensington extension builder’s ability to deliver a result that meets your expectations.
