Extensions- 29 Apr 2026
Heera, Jagthar and team was my first personal experience with builders. Let me tell you, it was a pleasure to have them do our porch and other renovations in the house. They are so courteous, hard working and provided a great service. Firstly, I had a comprehensively written quote breaking down all of the steps required. Heera then ensured to keep me in the loop of any developments/any changes of plan required, outlining the reasons why and options, making it easy to understand and work together to completion. Their finish was to a high quality and they would always go the extra step to ensure this. I highly recommend AS Builders for any job and will definitely use them again in the future, and would recommend to my friends and family also. If you are considering them, grab a free quote and go from there... That's what I did! Thank you AS Builders for our renovations!

JLita construction were hired after a competitive quote was agreed to carry out work on my kitchen extension project last year. Prompt and dependable Jetmir’s team worked productive long hours with a clear understanding of my wants and requirements. Where it was possible to accommodate they did. Any remedial work was quickly picked up and completed in good time to the required specifications. After completion of work each day, the space was swept and tidied and the space made as usable as possible. I am extremely happy with the work carried out and the attention to detail applied by Jetmir and his team and would, (and have already) happily recommend JLita Construction for any building works. More than satisfied. Many thanks Jetmir and team. Scott

Well, I do not usually write reviews, but this time is an exception. So after getting a number of quotations, I decided to go ahead with Fredi. The process was very smooth throughout, Fredi is a great individual and a reliable professional. The plan was to build a rear extension, but working with Fredi, we decided to commission him for the patio, changing all house flooring, kitchen, and two bathrooms. All have been delivered to completion with top-notch results. Most importantly, we have now a new family friend...Fredi the builder!!.. my kids say :)

Extensions- 22 May 2019
Jacob was very accommodating and flexible. His team were great and he completed the work nicely. There was some splatter from the cementing on to my neighbour's wall. He tried to clean it off but it wouldn't all come off. Therefore, he went out and bought some paint and repainted their wall. I would get him back for more work without hesitation. When looking for a builder - they have to be honest, work hard and to an excellent quality without cutting corners. They should be responsible to ensure neighbours property isn't damaged and provide consultancy as what we want and want is realistic can differ significantly! - and if any issues rectify them once the job is complete and of course provide good after sales. I have used several builders over the years - very few tick all of the above boxes. Jacob certainly does.

Extensions- 1 Feb 2023
We are in the last week or so of the extensive remodelling of the kitchen, utility room beyond plus bedroom upstairs. Mark Lomas and his team have been truly amazing, not just in exercising real building skills to blend the extension harmoniously with the existing Edwardian home but also in some imaginative problem solving as well. Costs have been spot on budget, save where I have caused additional work and fitting out, other than some unusual costs arising from some specialist joinery work which enabled the timber windows and doors to be exact replicas for others built 120 years ago. Honestly, I could not speak higher of the care and attention we have been given. I could get cross about the driving rain and the gruesome frosts and miserable cold, but that's a British Winter for you; Mark and his team certainly did not grizzle, and have stayed professional throughout. Circa £100k budget, so a reasonably size job and quite a risk for the builder - for my next project, I shall certainly use again in a heartbeat.

Extensions- 16 Apr 2026
I would not recommend this builder based on my experience. Instead of using crushed concrete they used soil to fill the house flooring for underfloor heating. 1 The project suffered from poor communication, repeated delays, and a lack of clarity around responsibilities. There were serious issues with the foundation works, which failed Building Control inspection and now require remedial engineering input before works can proceed. The site was also left incomplete and not in an acceptable condition. Despite substantial payments being made, key documentation, technical responses, and follow-through were lacking, leaving me to resolve major compliance and structural issues independently. My experience has resulted in delay, additional cost, and considerable stress. I would strongly advise others to ensure there is a detailed written contract, clear scope of works, and defined accountability
