Lovely father son business, professional, friendly guys. I asked them to build a plasterboard wall in order to create an extra bedroom in my house, the wall was finished well, within two days and they charged me a very reasonable rate, as a young women in business I find that tradesmen often try to overcharge me but these gentleman did not. They also took a look at leak that had occured which another professional plumber failed to solve and tried to charge me over £200 just to take a look! I have and will book them on a number of other jobs.

Roofing (Pitched)- 18 Jun 2025
I was in need of a quick roof inspection to make sure that the works carried out by another roofer were to a good standard. Shilhaad was very prompt to get back to me and had outstanding communication from quotation through to delivery. He was fair and impartial, turning around a report on the same day. He was very friendly, approachable and knowledgeable. Thanks to Shilhaad, I can go back to our initial roofers with some evidence on work that needs to be redone. My only regret was not using Shilhaad and his team to carry out the roof works in the first instance. Thanks again!

Conversions - General- 16 Sep 2019
Finding a builder you can trust can be so stressful, we know so many people who have nightmare stories. I am so happy to say we could not have chosen a better team for our garage conversion. Adrian and his team treated our home and this project as if it were their own. They showed up early every morning ready to work, no matter the weather and always cleaned up the building site before they left. Our next door neighbours had an extension done earlier this year and the team they chose left their property and home a mess every day. We expected this to be the case when we had our garage converted but Adrian and his team always left our property clean and tidy before leaving for the day. We loved how Adrian was attentive to what we wanted and made suggestions as well. The end result has exceeded our expectations and we know we will get incredible use of our studio for years to come. Any future projects we have we absolutely will be using Allushi Construction.

We have worked with Alex and his team at Swift Conversions Ltd twice now—first for a house extension and then for a loft conversion and general refurbishment —and we wouldn’t hesitate to choose them again for our next project. From the moment we received the quote to the final completion, Alex was incredibly communicative, reliable, and always had a can-do attitude. Despite the challenges of fluctuating prices in the market, he delivered the project within budget and stayed true to his word. His professionalism and trustworthiness are second to none. If you’re looking for a builder you can rely on 100%, Alex is the one to go to. Highly recommended!

Conversions - General- 29 May 2022
We took a longtime selecting our builder and so glad we chose Nero. Every builder must always think twice before working for architects on their own home! and Nero and his team worked diligently to meet our exacting standards with great communication throughout the whole process. We can't edit the original description of the works but we ended up completely refurbishing the whole of our ground floor, the rear elevation of the house, re-wiring, specialist lighting, re-plumbing, re-roofing, new front garden wall, victorian tiled garden path and external decking too. We also had a high quality parquet floor laid with new underfloor heating and each line of tiles was meticulously set out which looks fantastic!! Happy to recommend and give reference too.
