On Time Build was founded in 2002, as a building contracting company to take on refurbishment projects in London.


Based between two offices in Uxbridge and Twickenham, we have firmly established ourselves in West, South West and East London, completing multiple renovation projects in Notting Hill, Kensington, Chelsea, Fitzrovia, Richmond, Putney, Wandsworth, Bromley, Enfield, Clapham and Battersea.


Working predominantly with Clients as well as developers, we have become ‘the’ delivery partner for many residential refurbishments and house extensions.


We proud ourselves in always being able to deliver a project On Time, with great quality and success.

“I had the pleasure of being introduced to the talented contractors of OTB, when they were sub-contracted to the company, I used for my new extension plus loft conversion on my house in Twickenham.

They always came across in a very professional and friendly matter.

They were always attentive to my requirements and their level of workmanship was of very high standard.

I can certainly recommend the services of On Time Build without any hesitation.”

“It was a difficult decision to decide which builder to trust with our home. We wanted extensive re-modeling work done on the house, which required the removal of the bottom story of a wall while still supporting 2 floors above it. On Time Build completed the work without even leaving a crack in the upper stories brick work. Our house is now stronger than it was before, and our kitchen is a marvel to see. They have transformed a previously dark kitchen and corridor into a light open plan kitchen, with an attached family space. While On time build were very competitively priced, the reason we picked them was their keen interest in our project.”

“Qemal executed a large refurbishment for me in Battersea in September ‘16 and completed it in Easter ‘17. 

The work was carried out well and with a quality of workmanship that is a credit to his team , everything was discussed and agreed on a regular basis and all costs again agreed & stuck too. 

If any problems arose after completion Qemal came around and put the problem right straight away.

I would recommend OnTimeBuild for any type of building project , new build to like mine a large refurbishment .”

Michael M,


"OnTimeBuild completed a two story side extension and dormer loft conversion at our property.


The work was done to a very high standard with OTB and their team working very hard whilst being polite and clean at all times.


This was very important to us as we lived in the property throughout the project.


I would definitely recommend OnTimeBuild and would happily use their services again."
