Just a few words to say how delighted we are with the loft conversion Charles Jeffrey undertook for us earlier this year. It wasn't a straightforward build, but Matt and the team were determined to help us find the perfect solution - which we did! The whole experience was professional, efficient and diligent throughout, given the anxieties we may have had about such a large project. From Matt's first visit and readiness to answer our questions, we knew we were in good hands. Maria and Debbie back at the ranch were most helpful and courteous throughout. The timing and teamwork shown during the process was exemplary: the jaw-dropping dexterity of the MPH scaffolders; Alan's expertise in devising the staircase; Emirjon's patience with the plumbing and Jim's work on the electrics, and Kevin and his whirlwind team of plasterers. Last, but certainly not least, our heartfelt thanks go to Jonathan, who, with Luca, became a part of our lives for those few weeks. His professionalism and expertise, good humour, patience and innovative approach were a joy to experience and his legacy is a conversion that we are proud of and extremely happy with. We can't extol his virtues highly enough. We had considered other providers, but it became evident at an early stage that the choice of Charles Jeffrey was the only option.
Thanks to everyone who made this all possible.

Mr & Mrs Anwar of Enfield

We chose Charles Jeffrey for our loft conversions due to their customer service, they were extremely helpful from the beginning to the end.
We would not hesitate to refer them to anyone.
We thank all the staffs and a personal thanks to Matt who is always very helpful.

Thursday 3rd July 2014 - Mr and Mrs Roberts

Hi both

We wanted to say thank you for the fantastic and very professional job on the loft conversion. It went exactly as Cliff described and the work that Jonathan and Josh did was excellent, the results surpassed our expectations.

Kind regards


Saturday 14th September 2013 - Mr and Mrs Emden

Hi Cliff,

Sorry not to have been in touch sooner, my computer has a virus and email is only working sporadically. However, I didn't want to let the week pass without thanking you and all of the Charles Jeffrey team for repairing the loft render and honouring the guarantee.

As ever it has been a pleasure to work with you all. Jeff would have been proud.

With very best wishes,

Jacqui and Craig

To all at Charles Jeffrey,

Just a quick note to say how pleased we all are a tour new loft conversion. From the initial meeting to completion, I don't think that any part of the process could have been improved. Debbie, Hilary, Cliff and co. in the office were always incredibly helpful, making sure that everything from initial inspection to the getting the plans approved was carried out in the correct manner and to the required standard. The build itself went amazingly smoothly. Matt and Jason (and the rest of their team), apart from being incredibly polite, punctual and professional were also first-class craftsmen who took time to make sure everything was completed to the best possible finish. Before the build I was concerned that, as someone who works from home, that the noise may have been a distraction, but they couldn't have been less intrusive (amazingly, the whole build only took four weeks).

As others have said, a loft conversion is a huge expense, so you want to make sure it's being done properly. After spending quite a while at the beginning comparing loft companies I can safely say that, had we known quite how good Charles Jeffrey were going to be back then, we could have saved ourselves three or four months of procrastination.

Thanks again,

Alex and Nathalie, Highams Park

Because we are not easily influenced by marketing and sales hype, we have delayed writing this testimonial to Jeff and his team for four months.

The work was started at the very end of November and completed just over four weeks later. After the Christmas and New Year festivities, we moved into our much dreamed of loft conversion on 7th January 2013. Over these past four months we anticipated some teething problems - there were none. We expected the bedroom and bathroom to be chilly during the freezing temperatures of January and February… it was beautifully snug and warm with minimum of heating required. It is now a balmy 20 degrees outside and we expected the sales pitch of 'cool in the summer months' to be stretching the truth… it is a fantastically airy and cool retreat from the sun. In short, Charles Jeffrey do exactly what they say on the tin - they build fabulous quality loft conversions to the very highest standards.

But there is more to it than that.

We can add our names to the ever-growing list of happy customers with great pleasure. But perhaps more importantly we would like to congratulate the entire workforce at Charles Jeffrey for really caring about doing the best job they can. It has been a genuine pleasure to meet you all and to wave a friendly greeting from time to time when passing.

What makes our loft conversion so enjoyable is knowing that we have a quality build from first class tradesmen and the true peace of mind that our new rooms are built to last and guaranteed to be trouble-free from a Company that is also built to last. Thank you everyone at Charles Jeffrey.

A few words to say how pleased we are with our loft conversion, the job has gone so smoothly it has been a pleasure. When I began looking for a company to do the loft, friends and family said how inconvenient and messy the job would be. On having my first chat with Jeff he assured me that his teams would be of no inconvenience and there would be minimal disruption and mess. As I look back, Jeff rightly delivered what he promised.

It was meeting Jeff on the two occasions that convinced me I had made the right decision to go with Charles Jeffrey, and his standard and ethos went through the business. One key point that Jeff highlighted as an advantage over other companies was the 'one team one job', and it is this that has made the work seem hassle free.

Massive credit to all involved however I must give special mention to both Dan & Jordan, throughout the conversion they have been impeccable to have round the house, they kept me fully informed throughout, their craftsmanship with the conversion is remarkable, and I had full trust allowing access in my absence, they both made such an impact that even my six year old daughter enjoyed seeing or hearing them everyday. Credit also goes to the guys on site and for all involved in the company who after only being on site for approx. a week had to endure the sad passing of Jeff, for some this may have been a time of uncertainty and distraction but this did not get in the way of the job, a mark of true professionalism.

I am nearing the final stages of the conversion now with Ang (Jordan's dad) finishing the tiling and I am delighted with the all-round result, the scaffolding came down this morning and we are set to make full use of the room as of Monday.

"I was very wary about having building work done on my house. Charles Jeffrey has totally changed my opinion about British Building. The service from day one was exceptional. Totally professional and courteous. The work started on time, with the "A team" of Adam Craig and Rob in place. The team were clean, tidy, hardworking and kept us up to date everyday with the work that was going on. They worked through some awful weather without any delays. The work took less time than we were quoted and the end result is truly beautiful. I would highly recommend Charles Jeffrey to anyone wishing to have a loft extension completed."

February 2013 - Mr and Mrs Hobley

Hello Jeff, hope you are keeping well

Just wondering if you have an estimated start date for our loft?

Also, my wife and I bumped into the family across the road on East Walk who's loft you recently completed. She was very nice and could not speak highly enough of you and your team, she even went as far as to say she missed the team being there. She kindly invited us in to take a look and pleased to say we were very impressed, was good to get an idea of space and how the staircase fits etc.

Because she spoke so highly of the team who did hers, I believe she said his name was Dan, we would be very happy if he was also assigned to do ours. No doubt your other teams are equally as professional but it was reassuring to hear such high praise from a stranger.

Look forward to hearing from you



February 2013 - Mr and Mrs Patel

Jeff and Hilary

"Happy New Year to you and all your excellent team.

You wanted me to let you know when we finished decorating. We finished this at the end of last year and the loft is looking fantastic. Matt and Jason were just too great for words. Cliff the roofer, Angelo the tiler, Mark the flooring and the plasterers, the decorator, the plumbers, and all the co-workers completed their work to a very high standard. All of them were highly professional and very easy to get on with. People still can't believe how quickly the work was completed and on the excellent finishing. Hilary you have been brilliant to deal with and so was everyone else in the office. Jeff well done for building such quality teams. Please pass on our thanks to everyone who was involved with building our loft.

Jeff you said you might want to see the loft at this stage so let me know if you would like to do this".

All the best for 2013.

Best wishes M. & P. Patel

SIMPLY THE BEST If you're looking for a loft conversion look no further - seriously look no further. I interviewed all the big names wasted hours of my time and in the end went with CJ because my friend said everyone she knew used them and were "so happy" with their builds. Our team was superb, hardworking, thorough and trustworthy (I'd often leave the house for hours on end and they even took delivery of items from the postman for me). They even made helpful suggestions to my build "have you considered doing this" or "we do this a lot and it looks really nice" which they were completely right about. Everyone from the electricians to the plumbers to the roofers to the plasterers were all respectful of me and my property all were friendly and pleasant and all did a class A job. I really can't recommend this firm enough. They also did my build in an amazing 28 days and I would say the discomfort of a loft build was maybe a 4 out of 10 minimal disruption and the truth is we miss having the team around! I really can't recommend Charles Jeffrey enough they are a real class act and my loft is the envy of my street! Many thanks for a superb job well done. A. McEwen.

Mr & Mrs Peters

We would like to say a big thank you to all at Charles Jeffrey for the great job you have done on our loft. The team were very polite, hardworking and held upmost respect for our home. We would highly recommend this company. With thanks Mr & Mrs Peters.

Angie Thomas

I cannot begin to recommend Charles Jeffrey highly enough. The build quality and attention to detail throughout every stage of the process is exceptional. The company not only delivered on all their original claims but out-performed on all of them, even finishing ahead of schedule. Dan and Lewis, our builders, were professional and considerate and worked very hard to keep disruption and noise disturbance to a minimum. They are highly skilled craftsmen and it was a pleasure to have them in our home. We were central to the process throughout and consulted with at each stage of the build. Someone else in our street is having a loft conversion and I found myself feeling a little envious - such was the pleasure of our conversion experience! We look forward to the day when we have another loft so that we can repeat that experience.

Michaela Cook

You are reading this page because you're likely to be considering a loft conversion and trying to find out whether you should choose Charles Jeffrey. Am I right? Well, my family and I have just completed our conversion and there aren't enough positive words to describe our experience. Genuinely, it could not have gone smoother. We had Matt and Jason as our dream team and not once did I ever come home to that dreaded sharp intake of breath through the teeth and the words "we've got a problem". Together with the extended team of roofers, plumbers, electrician and plasterers, they were polite, professional, efficient and friendly. Everything happened when they said it would. No fuss. No drama. Nothing to hide. I would wholeheartedly recommend the team to anyone considering a loft conversion - what you see is what you get and no hidden extras or nasty surprises. What we got was a fantastic new master bedroom and ensuite that we are extremely happy with. A big thank you to everyone involved.

Sarah - 2 Sep 2011

Fantastic job, quick turnaround and Jason managed the team very well on site. We now have a great space which has become our master bedroom and en-suite bathroom. This has given us the spare room we desired and already benefited when our various family turn up to stay, having previously had to juggle our sleeping arrangements with me usually ending up on floor. We love the juliette balcony and doors, the natural light, fresh air and cooling this provides to us is glorious. Now it is decorated and furnished it is hard to imagine how we managed previously. Just want to say thank you, there were no unexpected surprises and you gave us exactly what we discussed at our initial consultation. So many people have already had a look and well impressed, particularly at the quality and speed of the work. Z & S.B, Enfield

DJ - 16 Aug 2011

Every workman who has been to the house and worked on the loft conversion has been both friendly and professional. We are extremely satisfied with the work carried out. Adam and Alfie are the nicest workmen we've ever had around to the house: very hard working, friendly, and professional. We would have no hesitation in recommending Charles Jeffrey to anyone considering a loft conversion. I have, in the past, been told how messy a loft conversion is, but Adam and Alfie made every effort to reduce mess and worked in a tidy manner throughout. They also made every effort to maximise the space available, giving professional advice, and are very conscientious workers. They should be, and I know that they are, very proud of their work. We also enjoyed their singing and camaraderie, and so did my neighbours! Also time keeping was excellent and so was the flow of the work. S & DJ. Enfield

Dalton - 3 Aug 2011

From my initial enquiry to the finished job I was dealt with in a professional manner and was advised and informed all the way, this was particularly important to me as my wife and I hadn't done anything like this before we were thrilled with the outcome and got more than expected. I would not hesitate to recommend them.

26 Jul 2011

An excellent service from Charles Jeffrey, nothing was a problem. All obstacles were overcome efficiently and positively even my neighbour is considering having a loft conversion with Charles Jeffrey as she is so impressed with the quality care and attention to detail taken by the workforce. I have to say that when viewing the company website I was not mislead in anyway as to what I should expect, Hilary kept us informed and was able to answer any questions along the way. Highly recommend if you are considering a loft conversion.

Mrs B - 22 Jul 2011

Outstanding service from start to finish. Staff polite and sensitive to our needs. Could not fault this company in any way and would not hesitate to recommend a loft build to anybody after seeing the finished loft conversion. The french doors make us feel as though we are in a luxury hotel room! My husband and I are over the moon with what feels like a completely new home thanks to Charles Jeffrey and his team. Many thanks to the competent office staff especially Hillary who kept us informed along the way.

M - 22 Jul 2011

Charles Jeffrey are the best. In the past it has been awful experience when the builders have been in our house. Not so with Charles Jeffrey, workers always polite and kept any disruption to a minimum. The finished loft is just great and we love it. Think anybody would be hard pressed to find a loft conversion company who have as much attention to detail. A big heartfelt thanks from all our family.

Pmsmooth - 22 Jul 2011

I did loads of research before deciding on Charles Jeffrey to build our loft conversion and having now had my loft completed I'm in no doubt that I made the right decision in selecting them. The whole job from start to finish was carried out with total professionalism and all work has been finished to a really high standard. The staff both in the office and on the project were very helpful and communicative and were able to accommodate every request along the way. Highly recommended. Pete - Enfield

Snowbeard - 22 Jul 2011

We loved the courtesy and professionalism shown throughout, even when problems arose which were outside their control. The layout chosen and the workmanship were excellent. We wish we'd had the remaining original roof tiling renewed at the same time. And maybe we should have waited another month before we had the shower-room tiling done. That's just a pointer for people planning on having a loft conversion done. I can unreservedly recommend CJ.

HT - 21 Jul 2011

Charles Jeffrey built our loft , it was a wonderful experience and the staff were very helpful and communicated thoroughly throughout. We had a stress free experience.

Sabina - 6 Mar 2011

Charles Jeffrey was highly recommended to me by two people and I am pleased to say that the company lived up to their name. I was particularly pleased that my adaptations to the design and my concerns were always willingly received and heard. The team that built my loft were completely trustworthy and any qualms I had about disturbance and disarray soon disappeared; it was a pleasure to have them working in the house. All my visitors have commented on the high standard of the workmanship.

Mike the Gooner - 22 Feb 2011

I can strongly recommend this company. We have now had two loft conversions from Charles Jeffrey. Each has been superb in quality and workmanship. The work started exactly on schedule, and most importantly, finished on time. All the planning and approvals were handled efficiently and quickly. Jeff pays attention to the smallest details and every part of the work was done by a specialist tradesman. The work proceeded so quietly and efficiently, we didn't even know they were there. We now have a beautiful fourth bedroom with a Juliet balcony, and with a fabulous en-suite bathroom. After sales service is excellent. If I need a third loft, I will definitely be calling on Charles Jeffrey again.

Franny G - 22 Feb 2011

I would highly recommend Charles Jeffrey Ltd. Not only was the whole process stress free (done professionally, cleanly & quickly), I now have a loft conversion that I could not be more pleased with. It has been built to a high standard, looks fantastic and is exactly how I wanted it. There is not one thing that I would change.

John B - 21 Feb 2011

February 21 2011 We had our loft conversion finished by Charles Jeffrey a short while ago and simply its fantastic.Right from the start Jeff organised all the paperwork,drawings etc; and within five weeks our loft was completed.We would like to thank Jeff, Hilary so friendly and helpful and our workmen the roofers, plumbers and the electrician whose work was of the highest quality. Our special thanks goes to our team of Matt and Mark top guys who always kept us informed of what was happening and helped with a few changes that gave us a quality loft with a Juliet balcony overlooking the park. If you want a quality loft conversion then look no further than Charles Jeffrey. Once again many thanks John and Lesley.

Mrs S - 18 Feb 2011

18.2.11 Very happy - We chose to have a loft conversion instead of moving house (moving costs were one issue). The actual conversion was completed in four weeks and we are very happy with the finished product. We had some admin issues at the beginning but Charles Jeffrey solved them for us swiftly. The team that were assigned to us were informative, friendly and hard working. They were working in very cold conditions but just got on with it. The paperwork/designs were very clear and the lady in the office was always friendly and responsive to any problems we had.

4 May 2010

A superb loft conversion. By Grahame@BHP As with all new projects around the house, you do worry. But from the first (& honest) assessment from Charles Jeffrey Ltd. of how they might be able to help you realise your ideas. To the extremely prompt and effective aftercare of sorting out any adjustments. They really do look after you. A smooth pre-planned operation took place, with a main team always present and other specialists coming to complete their tasks. So pleased that we went for it ... and with Charles Jeffrey Ltd. Highly recommended.

Anna Antoni - 26 Apr 2010

I used Charles Jeffrey for my loft conversion and I couldn't have been happier. I was very dubious about taking on such a large project and after having some bad experiences in the past with builders I was worried to say the least. However, Charles Jeffrey and the team made it almost a pleasurable experience! They were punctual, polite and totally reliable. The quality of their work is outstanding - from the build to the finishing touches. The team ensured I was kept totally up to date with the loft's progress and I was always informed of what was going on and how it was all coming together. A large project was made so easy really - I didn't have to do anything, and having such a nice team working in my house made it even better. We were totally thrilled with our new build - it really is lovely. If I had to do it again - I wouldn't hesitate in using them again. Highly recommend them for anyone wanting to build a loft conversion.

Andy - 8 Apr 2010

Thank You all at Charles Jeffrey We have nothing but praise for this company. In the past having the builders in proved stressful. Not with Charles Jeffrey! From the first visit through to completion they have been first class, and we are thoroughly delighted with our new loft conversion. Highly recommended.

To: Jeff Subject: UK Trades Confederation Hi Jeff,

Hope you are well. My studio loft is looking good - flooring down - wardrobes installed - I have some finishing off to do.

Russdales of Winchmore Hill fitted the flooring for me and they are a member of the UK Trades Confederation. I need to fill in a feedback form to comment on their efficiency, standard of work etc... I am being asked to recommend another company and wondered if I should put down Charles Jeffrey as a company 'which works to a high degree of quality and professionalism'?

I await your response as to whether this is appropriate.

Best regards, Sabina

Hi Jeff, My apologies for not getting back to you sooner but the loft conversion is virtually completed. The plumbers are going to smooth out a few things like taking care of a minor leak in the face basin as well as capping off the sewage line vent which they could now get to after the scaffolding was adjusted on Saturday. I've already signed off the completion of the construction part and the building inspector has already visited. I believe he would probably visit again once these minor adjustments are made.

I'm not sure about the next stage but I've made arrangements for a decorator recommended by Darren from CJ to advise/quote on painting and I believe tiling of the bathroom.

While all has gone smoothly from what everyone has said and what I can see, I and the family have been trying to recovery from the loss of xxxxx and it is extremely difficult to focus on other matters at the moment. The Charles Jeffrey team has been very sensitive and supportive throughout the whole project and I can't thank them enough for giving us time and space when we needed it and yet still delivery the loft within the time promised. Even though xxxxx never asked for much I know she would have been so pleased to see the amazing work you all did and she would have loved the room, I just know it...

My warmest thanks and appreciation to you and your team especially Darren, Charlie, Rob and Tony, they are really great guys to have in your corner, respectful, conscientious, skillful and all round good people to deal with.

Best Regards to all. Terry
