Plastering- 4 Oct 2024
Mr Rifat did an excellent job for plastering rooms and i would recommend him to everyone highly. The work he has done is to a very high standard and completed in 3 days. His quote was very helpful and comprehensive and he was helpful and very kind and calm. He did not take a break from doing the work, even though i told him to take a seat for 5-10 minutes. He is a very hardworking person. I think anyone to catch him to do a job for themselves is very lucky. I recommend him to everyone because he knows how to do good job.

Bathroom Fitting- 15 May 2017
We hired Inside/Outside to re-do our bathroom. New sink, bath, toilet, tiles, lower ceiling, re-hang the door and move the radiator. They were polite, honest, professional and very hard working. When they came round to quote they were noticeably more thorough and showed more attention to detail than others. Their quotes were very competitive, their work was good and they removed all the rubbish as well. They also came back afterwards to check everything was working and to deal with a couple of 'snags'. We will be using them again.

Bathroom Fitting- 24 Oct 2025
We had 2 bathrooms refurbished at the same time by Romulus and his team over a 4 week period. Both bathrooms were completed on time and on budget. We were looking for 2 functional bathrooms, but ended up with 2 very high spec bathrooms within our original budget, and couldn't be happier with the high level of service and professionalism by all his team. We will now move forward and have his team refurbish our kitchen.

I recently hired LLC Projects Limited to refurbish my ground floor and add a new bathroom, and I couldn’t be happier with the results. From start to finish, the team was professional, reliable, and truly cared about delivering quality work. The new bathroom looks amazing, and the ground floor transformation exceeded my expectations. Communication was great throughout, and they kept everything on track and tidy. The crew was friendly, and they handled any concerns I had quickly. I’d definitely recommend LLC Projects Limited for any home improvement work—they’ve earned my trust, and I’ll be calling them again for future projects

I recently completed the building of an orangery extension (with skylight) to my semi-detached townhouse in NW London. The extension was to be used as a new kitchen while the existing kitchen converted to a living room. I awarded the contract of building the extension to Anthony and I was pleasantly impressed with the quality of work delivered. Anthony Project Managed the entire process from beginning to end and ensured that all my expectations were surpassed. His hands-on attitude to every detail of the work was quite reassuring. I am glad to say that Anthony and his team are very good professionals and they delivered the project on time and within budget, even going over and beyond the original scope of works in order to ensure that all my latter requests were addressed appropriately.
