Hertfordshire Customer Reviews & Testimonials

Michael Power

A absolute pleasure to have used, and dealt with Concept Lofts for my loft conversion. They were extremely efficient in getting the job done within the timescales stated and always ensured the site was clean.

The fit and finish really is as good as it gets, with some late changes to my spec being managed into the job without fuss and to an exceptionally high standard. I can and have, highly recommended Concept and will continue to do so in the future. A truly professional company that you will not regret employing.

Collaborative, bespoke and highly professional, Jake and his very talented teams have been a joy to have on-site. Their work is not only of an excellent standard but the stream of communication and receptivity has been constant throughout. What could have been daunting has turned out to be a swift and brilliantly engineered operation. I have no doubts in recommending Concept Lofts to anyone who needs a quick turn around with attention to all the final details.

Lisa And Nick Y

Concept lofts were brilliant and I would have no hesitation in recommending them for loft conversions.

Jake has excellent attention to detail and great practical advice, his whole team were so friendly and hardworking, finishing the work on time and far quicker than anyone else was quoting to do.

We are delighted with the quality of our loft conversion, and have so many compliments on it from anyone that sees it. Thanks so much Jake and all the guys.

Ammie Dear

Excellent loft conversion! The speed & quality of the work was second to none, the team of builders was superb: helpful, reliable, tidy & polite. Jake was always at the end of the phone to answer any questions and also had loads of great ideas. The price was fair and we will use Concept lofts again in the future. Definitely recommended! We are happy to show photos if need be.

Karen McKinnon

Jake and his team completed a two bedroom one bathroom loft extension on my Victorian terrace house in six weeks and to a very competent standard. The finish is exactly as I wanted it and additional work was carried out on other areas of the house at a reasonable cost and within the same timescale. Jake was responsive, open to criticism and adaptable as much as he and the plans could be. I would recommend him and his team highly.

Dave Billington

Concept Lofts were the only company to turn up on time to quote, gave a competitive price and had the ability to communicate effectively. Jake was also the only one to assure us our box room wall wouldn't need to move to make room for the stairs, all the others said we needed to move the wall and lose space in an already small room. 

When you are spending this much money on a project you want someone who can answer your questions quickly, be professional and efficient. I'm pleased to say Jake and his entire team were all of this. Very friendly, hardworking, tidy and polite. They are also fast and had the entire project completed within 4 weeks. 

We are very pleased with our new loft conversion and wouldn't hesitate to recommend or use Jake and his team again in the future.

Rachael Bamford

After obtaining a tonne of quotes, a friend recommended Jake and his team and I’m really pleased they did. Not only was his quote competitive but he did everything that he said he would do and more. All his team are clean, tidy and polite and they also go out of there way to help you with whatever they can. I had been told by other people who had loft conversions to expect something to go wrong or for it to take a lot longer to complete than expected but I am happy to say that not only was it wrapped up within the 4 weeks quoted, but the only thing to go wrong was at our end with the flooring and they even adapted to that to make sure the build stayed on track. We can not recommend them highly enough.

Simon McCullagh

We are so pleased with the results of our loft conversion. From the initial phase through to project end Jake and his friendly team were exceptional and perfectionists ensuring excellent workmanship. Jake offered very good advice regarding design and the conversion project. Nothing was too much trouble, and throughout the works the team were reliable, considerate and always tidied-up at the end of each working day. Concept Lofts were very price competitive and the project was completed within the estimated timescale. We are pleased that we chose Concept Lofts and would definitely recommend them.

Jordan Bostock


After obtaining half a dozen quotes and meeting with various companies we decided to go with Concept Lofts. Not only was the quote competitive, but they explained the process really clearly and came up with the most creative suggestions as to what we could do with the space and provided us with the best plans for our needs. The work started when they said it would, was carried out by who they said and they were finished sooner than when they said they would be. The staff were clean (tidying up after themselves), polite and courteous (telling us when there was going to be banging etc. As we have young children). We really couldn’t recommend them highly enough and always offer for them to show other potential customers our loft. On a separate note, we completely underestimated the extra space gained! We wish we had done it years ago!

Concept Lofts are a professional, reliable company. At the end of each day they ensured the house was tidy and clear of any rubbish or mess. The workmen were all friendly and very polite. The finish of the loft is great and it was great watching how fast it all went up.
Top workmanship.

Danielle Laws

I highly recommend Concept lofts. The Concept team were professional, hard working, clean and polite. Any queries I had were answered and dealt with swiftly. The project was delivered on time and on budget. The space that we have gained is amazing and has finished our family home off perfectly.

Concept Lofts created a fantastic loft conversion in my house. From the planning stages through to final fix they were very knowledgeable and efficient. This is a professional and experienced team producing high quality results. Thank you Concept Lofts.

Alex Cruickshank


Jake did an excellent job for us, we are really happy with the way it has transformed our house! We had a few quotes and although Jake wasn’t the cheapest his was the most professional and I’m glad we chose to go with him. Our quote was very detailed and the build went quicker than the schedule said which was a bonus! it was about 18 working days from start to finish for our loft which was brilliant. Jake was very informative all the way through offering up his thoughts on the layout and changes that could be made to utilise space or help the building flow better.


Waltham Abbey

We had an L-shaped loft conversion completed in 5weeks to a very high standard. The workmen were professional, punctual and reliable. They were very respectful of my neighbours and ensured front and back of house were kept clean and tidy. First builders I have nothing negative to report. I only complaint is that they only do lofts. We would love to have them back to do other jobs. Good builders are hard to find.

Richard Wilson

Waltham Abbey

We decided to have a loft conversion in May 2017. After inviting 3 companies round to give us a quote, it was very clear that Concept Lofts was the choice for us. We were impressed with Jake’s attention to detail and he talked through the whole process with us. Once he knew what our requirements were he sent us a floor plan within 24 hours. Our requirements were:

a) An L-Shaped Loft Dormer comprising of a master bedroom, plenty of wardrobe space, and separate bathroom.

b) Construction of a new shower room on the 1st floor

c) Construction of a hallway with double doors on the ground floor.

Jake invited us over to another property he was working on. The property had the new staircase just fitted and all the loft rooms were plasterboarded, ready for it’s second fix and then skimming. Jake took us around the property and we had discussions of how things could look in our new loft room. This not only gave us a valuable insight into Jake’s quality of work, but also demonstrated how generous Jake is with spending time with you, even during a busy building site.

On the 3rd July 2018 Jake and his team started work on our property, and by the beginning of August the Loft was constructed and so was the new shower room along with all plumbing and electrical fixes. Jake was on site throughout the construction and he and his team worked fast without compromising quality.

One of the things that sticks out in my mind is how Jake’s team always tidied up at the end of a tiring day. They are a very friendly and hard working team, always arrived on time and it was a pleasure to have Jake, Matt and Karl work on our property.

My family love the finished project. The kids love having showers in ‘their new shower room’ and my wife is very happy with the spacious wardrobe room which allows for even more space in our new master bedroom. Our separate bathroom is beautiful too. A very big thank you to Jake and his team.

For my wife and I, the most stressful part of the whole process was worrying about finding a competent builder that you can trust to demolish and then build up your house again (we have all heard the horror stories), but you won’t have to worry about any of that with Concept Lofts. I recommend them highly.
