Tiling- 31 Aug 2026
Excellent service from start to finish! I chose Mo for our bathroom tiling and bathtub installation based on his reviews, and he didn't disappoint. Mo and his assistant finished in just two and a half days, working quickly without compromising on quality. They kept the space tidy, cleaned up daily, and even stored the leftover materials in our garage. Professional, reliable, and highly recommended!

Gas Work- 7 Oct 2025
This provider took my money but never attended my property or carried out the work (a report on already completed plumbing works). All he had to do was write a report to say that the repair works were complete. On the day he was due to attend he never let me know he was on his way or that he wanted to come early morning. Then he went to a nearby apartment a few streets away and said he had attempted to come so it was my fault. Then he said he would do the report remotely I must send him pictures, after sending him pictures he said he wanted to visit site so we were back to him making an appointment which of course he really did not want to do. 3 months later no sign of my money or a very simple report that a child could have done. He also has not returned my money (£120). I can now see why he insisted he be paid in advance because he is a time waster with no confidence in his own abilities hence payment in advance, so that when he disappoints the customer he can still get paid.

Extensions- 31 Aug 2024
BS Loft Conversions are reliable, honest and operate with integrity. I recommend them to anyone who is looking for some building work whether they are big or small projects. They arrive on time, work hard and leave the site clean and tidy. Anxehlo always takes the time to answer any questions we may have and talks us through the process before providing us with all the options available from repair, replacement or re-instatement. As a novice to a huge development, it was difficult to find builders you can trust but, Anxhelo made that process easier, restoring our faith in construction work.

What to ask a The City extension builder before hiring?

What qualifications and experience do you have as an extension builder in The City?

An extension builder in The City 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?

Your The City extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in The City?

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 The City extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most The City extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
