Overall, very pleased with the quality of the build. Communications from everyone from first call into the office to get a quote, right through the build was great. Everything moved along at a good pace with no surprises on the budget. All finished on time. Very Happy.

Mrs McRobert

Thame, 2026

In selecting Charles Grosvenor for our loft conversion, we obtained three competitive quotes from specialist loft conversion contractors on a turnkey basis contract as well as three competitive quotes from general builders using a traditional design and specification. The general builders were much more expensive and would have been using various sub-contractors, along with having multiple deliveries and accessing the loft through the house, as well as extra costs for planning/building control approvals. Charles Grosvenor were not the most competitive although the quotes received were very close but we chose them from their on-line reviews and the discussions we with them about the work, the on-site process and access etc. Our loft conversion was reasonably straight forward being a Velux window installation along with creating two new rooms with an access staircase. Charles Grosvenor dealt with everything, design, planning and building control approvals and kept us informed of progress along the way. Once we had an agreed a start date, an access/platform was erected and then all of the materials were delivered at the same time and stored on the scaffold. Apart from accessing the loft through the existing hatch all materials were taken through the roof not the house. All of the team, admin, project management and trades were polite and professional, the on-site team cleared up every day and disruption to our daily lives was kept to a minimum. Workmanship was exceptional with very minor snagging on completion. The team were very helpful and worked with us on minor changes etc. We were told that the work would take three months and it went slightly over but only due to Christmas closure in between times. All in all, we were very impressed with the process and the finished works and would have no hesitation in recommending Charles Grosvenor. There is only one other thing to bear in mind is to have a large supply of sugar as every one of the team who came to site had I in either their tea or coffee!

We're very happy with our loft room and ensuite. The build team were great. We were also delighted with the matching of the stair parts.

Mr & Mrs Jack

Oxford, 2026

Really Professional and Friendly Service. Had an existing loft conversion we wanted extending and split into two rooms. The service was exceptional from start to finish, with weekly check-ins to update us on progress and give us a chance to ask any questions. Every member of the team and tradesmen we interacted with were very friendly and approachable and also obviously very knowledgeable. After having mixed experiences with previous building work done to our house, Charles Grosvenor really stood out in comparison for their overall service and build quality. We are delighted with the end result, and have a lovely new space for our childrens bedrooms. Would happily recommend to anyone considering a loft conversion

Mr & Mrs Wardle

Worcestershire, 2026

Really great company, I highly recommend them since they do it with care. The Loft Conversion looks really great. Thanks to the hardworking builders Bradley & Jay, the very skilled helpful plumber Rob , Brandon & Ben the electricians, as well as Richard who plastered the space nicely. Paul was very reliant, understood what needed to be done from what we addressed to him. There was some delays that caused the project to be halted for a period of time than expected. However, because of their reassurance the project went smoothly and everything we needed was done beyond expectations. Their tradesmen are professional with great work ethics and very approachable.

We’re are absolutely delighted with our Charles Grosvenor Loft Conversions loft. From start to finish - faultless. Highly recommended

Mr & Mrs Viney

Bicester, 2026

Life-changing 5-star experience! We are absolutely thrilled with our new loft conversion by Charles Grosvenor. From the first consultation, they understood exactly what we wanted for our rear dormer and gable end loft conversion. Most work was done from the outside, so it hardly impacted our daily lives. Russ and his team managed everything perfectly with professional carpenters, electricians, plasterers, and plumbers throughout. The new staircase looks like it’s always been there. If you're on the fence about the cost, it is well worth the investment for the space and value added!

We are very happy with our loft conversion. All the staff from head office were very helpful. We greatly appreciated having weekly site visits to discuss the progress of the work and to be able to talk about any concerns that we had. All of trades people were very friendly and respectful. The work was also completed to a high standard by the fitters, electricians, plumber and plasterers.

Excellent LOFT Conversion 'I can't recommend Charles Grosvenor highly enough. The whole process from the initial quote, through to final completion was incredibly professional and (perhaps most importantly) had the highest level of customer service and support, I've ever experienced from a building company. The final result is brilliant and the whole team (of which there are many) were polite, quick to respond and supported every step of the way. Definitely recommeded.'

'Charles Grosvenor Ltd converted the loft on our quite large 1970's house to create a new staircase and two bedrooms each with en-suite bathrooms. Also, the work included the replacement of the existing CH boiler and tank. After the initial review by the surveyor, it appeared that the conversion was not going to be possible due to a combination of the complex existing roof structure and the logistics challenges of moving materials to a location from a roadside truck to the worksite without damaging our drive. Each of these challenges were overcome by Grosvenor's. The loft design was reworked several times up to and including during the installation. The materials supply issues were overcome by building a temporary large elevated platform on the front lawn which could be reached by a crane from the road. The existing driveway was given temporary protection by laying sheets of timber when heavy vehicles were needed to make drops. Throughout, great care was exhibited by all of the workmen who visited. Overall the time and cost was revised throughout the job to reflect agreed changes. There was a time overrun but largely due to additional requests from ourselves and third party work such as decorating. Throughout the job, we felt included in the decision making and were supported by the project manager. The impression we were left with was very positive and would therefore have no reservations in recommending them for even the most complex loft conversion.'

Mr M

'We have had an outstanding experience with charles Grosvenor loft company. Their professionalism was evident from the start to finish. It has taken nearly two years from our first initial conversation and there have been times when I wanted it to happen so much sooner but I must say they are well worth the wait. (Back log partly due to Covid when we initially booked!) The carpenters, builders, and plasterers were not only skilled but also meticulous, ensuring a tidy cleanup every evening. The whole team in the background is wonderful, from my first conversation with Sarah I knew they understood exactly what I wanted. I have to compliment the whole team, Ken, Sarah, Maxine, Alan, Adrian, Hayley and I’ve loved my weekly visits from Bob to check up on all of the work. Our builders/carpenters Rich and Lee were great from the first day on site and ran everything past me first. We also struggled with a skip but yet again they worked around all of this. The actual build was so much quicker than anticipated as these guys work so hard considering we have had a large dormer with a half bonnet roof. Unfortunately we had a nearly 3 week wait for plastering but yet again well worth the wait as the finish is perfection. Eddy the plumber also super helpful and professional. I highly recommend their services for anyone seeking a seamless and top-notch loft transformation. I’ve already recommended them to two friends, I just wish they did other building work as it all runs so smoothly due to a fantastic team. Huge thanks to you all. I will try and add pictures once we’ve finished decorating!'

"Charles Grosvenor recently completed our loft conversion. My roof space was tight and if I am honest I was worried about the overall head height. There really was no need to worry as the end result is perfect. The build started a little earlier tha planned which was perfect for us. The builders were very good. Clean, tidy, punctual, with great communication making sure I was happy at each step of the dormer installation. Nothing was too much hassle even when we wanted to change the layout a little. Just and second fixes for electric and plumbing went well. Again the guys are a credit to the Grosvenor team. This is the first time that I have ever had any kind of building work done, and could be quite daunting. The team made this really easy, stress free and problem free. I really hope that all building companies are like this! I would kost definitely recommend Charles Grosvenor to anyone thinking of a loft conversion. More than happy for people to come and see the work carried out! "

Mr and Mrs H

"The whole team are incredible! From the planning to the snagging team, we received A* service. I was able to contact someone by phone or email. Russell came every week to check the site, any tweaks were ironed out and the office planned visits from plumbers, electricians etc within a great timeframe. I would 100% recommend this loft company for their sheer dedication in providing a seamless service. It's not every day you can truly say that about a company. We are thrilled with our master bedroom and bathroom en-suite. Excellent work gang"!!

We are really pleased with our loft conversion. It has given us some really useful extra space without too much loss of space on the first floor for the new staircase. For such a big project there was minimal disruption and the work was project managed seamlessly. The girls in the office were really helpful so we always knew what the plan was. Thanks to everyone involved!

THE TEAM
Overall the work done by Paul and Andreas was very good and we were really pleased. They were both very good at explaining things without being patronising when I didn’t understand things Very tidy and minimal disruption for the amount of work being done. Andreas was incredibly conscientious. I’ve never had a tradesperson in the house before who has tried so hard not to disrupt me and to tidy up after himself. Huge thanks to Andreas, he was fab. Ben the electrician - Great – efficient and tidy. Ed the plumber - Ed was great. Really helpful and good at explaining things. He seemed to really know his stuff and had some useful suggestions re the layout of the bathroom Office Staff - Brilliant, really, really helpful"

"Overall it was a great experience, we always felt informed at every stage and the co-ordination of resources was very organized. The fitting team and trades were brilliant, really nice bunch of guys, hard working, dedicated and approachable. Even though we have a small property, the quality and usability of the new space is excellent and has added value to our house and solved our space issue perfectly"

Mr Oswald

Bracknell

"Generally everything was very good. I have put the plasterer and electrician in the excellent column, plasterer did a superb job and electrician worked hard to make sure I didn’t need additional consumer unit and to make sure no conduit was used…..I feel that both Paul and Eddie were excellent to deal with, they listened to my queries and were happy to spend time chatting about details. In all I am very pleased with the whole process which was hassle and stress free for the most part. If I was to run another job with yourselves I think a little more questioning on site via phone would be good to possibly deal with any issues rather than at snagging phase and perhaps a bit more info up front about fixtures and fittings so I know what to expect would have helped any miscommunication. Thanks for a great job"

Mr Hartwell

"The end result is superb and our dealings with all Charles Grosvenor people, and sub-contractors, were congenial throughout, which I think is a credit to you. We would have no hesitation recommending Charles Grosvenor to others, and indeed have already done so"

Dr & Mrs Grieve

Broom

"In an excellent company you have a number of employees who are simply outstanding. The service delivered surpassed our expectation at every stage of the build and we are delighted with the final loft conversion. A big thank you to you all, particularly Dave who even turned up on Sundays to keep the build on track, Hayley for her efficient communication, Russell for his excellent project management, Alan/Darren for their skilled contributions. For a company we selected from the internet – WOW!"

Mr & Mrs Murtagh

Cheltenham

"Having gone through a big building project a few years ago, we never would have believed that a firm could provide such consistently good service all the way along – from sales, to architect, builders, sub-contractors, office staff, and management, our experience has been wholly positive. I would also like to mention the finishing work from Dave and Leon, who were both really obliging"

Mr & Mrs Griffiths

Birmingham

"We wish to take this opportunity to say how delighted we are with the loft conversion recently carried out by Charles Grosvenor. Paul, Carl and Andy were always reliable, helpful, hardworking and incredibly tolerant of all our many changes and cannot be faulted. As you know, our plans and the age of the house were somewhat of a challenge and very special thanks must go to Paul without whose knowledge and guidance there is no doubt the loft rooms, especially the semi-decagonal back dormer, would not look anywhere near as fantastic and impressive as they do. Everyone has been pleasant and professional from the girls in the office to Darren the plasterer and John the plumber. In contrast to the stories we have heard about other companies, Charles Grosvenor has restored our faith in the quality of British builders by delivering a finished product beyond our expectations whilst being totally in keeping with the character of the house and the surrounding conservation area. The quality of workmanship was consistently second to none and this was reinforced by there being virtually no snagging. All people who have seen the finished loft rooms have likewise been very impressed. We will of course recommend you to anyone considering a loft conversion and hope that our paths may cross in the future – we might just do it again! With very best wishes"
