Highlights

"Fred and this team did a great job with my bathroom refit including useful advice about the best products to buy to make the most of the space. The guys were punctual, friendly and professional and completed the work to an excellent standard. I’m really pleased with the finished bathroom. The team also completed a number of other small jobs to the same great standard."

"I am a returning customer of this firm. Dan and James, with the some additional help, have completed a complete refurbishment of my kitchen, bathroom, and two bedrooms. The work was completed within the time frame to an extremely high standard. They arrived on time each day, where polite and considerate considering we were living in the property whilst the work was undertaken. This has been phase one of the refurbishment, phase two, the upstairs to be undertaken within the next few months."

"There are four stages of getting major building works pre-planning, planning, the actual works and post-completion touches. We chose Grosvenor Builders and during each stage of the process we were guided through all aspects which included advice on optimisation budget, quality and comfort. We met with many prospective builders but finally decided to go with Grosvenor, despite a waiting time of over a year (which in itself was an indicator of quality). During the preplanning stages Fred was the only person who had a true ‘consultative approach’ and took detailed notes on what we wanted and possibilities based on our design. After we decided to go with Grovenor, we were constantly in touch with Fred who guided us on timings, helped with moving our stuff and set up the temporary kitchen. During the build stage, when actual works were taking place Dan and James were the best we could have asked for as they always had time to discuss and suggested options (we ended up getting an extra study room) – they actually became part of our family and now that they have left we actually miss have them around (they have an open invitation for lunch / dinner whenever they are working in the neighbourhood). Finally, post completion (and settlement) Fred has proactively been in touch for some ‘touches’ and optimisations which one comes across when newly constructed area is brought into use. We wholeheartedly recommend Grosvenor Builders and welcome newest members of our holiday card list."

We hired Grosvenor Builders to renovate our kitchen. This included structural work (knocking down an internal supporting wall, inserting steel beams, knocking down and rebuilding a stud wall) as well as laying new flooring with underfloor heating, assembling kitchen cabinets, new cupboard doors and new internal doors, electrical and plumbing work and painting. From quoting for the work to finishing the job, Fred and his team were extremely efficient, trustworthy and reliable. Fred project managed the whole process and kept us informed at all stages of the renovation. His team were courteous, tidy and hard working. If they thought something wasn't going to look right they informed us and talked through options. They always listened to our wants and did their best to accommodate us at all times, whilst completing the work to a very high standard. We have no hesitation in recommending Grosvenor Builders to anyone.

Grosvenor Builders completely refurbished the kitchen while I continued to live in the property. Daniel and James were punctual, tidy workers. They are very personable and a pleasure to work with. Their attention to detail was impressive and reassuring. The time estimate for the job was accurate as was the initial quote. When, for reasons beyond their and my control, the cost increased I was notified in good time. I recommend this company without reservation.

Worked with Grosvenor Builders and Howdens to design the new kitchen. Once agreed Grosvenor undertook full liaison with Howdens. Grosvenor undertook the complete removal of the old kitchen, re plaster, new electrics and altered plumbing, decorating and fitting of new kitchen and all appliances. Old kitchen, appliances etc all removed and taken away. The team were efficient and professional. Tided up every night before leaving. Would highly recommend Grosvenor such works.

100% recommended. From the first meeting with Fred great, honest communication. Grosvenor dealt with Howdens and continually consulted with us during the project to ensure that we were getting what we wanted. The team were always punctual and respectful of us and our home. Thank you to Fred and his team. We’re delighted with our new kitchen.

Grosvenor Builders first contract with us (bathroom refurbishment) was c.12 years ago and they have since built our side extension, created a new kitchen diner here, refurbished relative's kitchens, bathrooms and garage conversions - all to the same very high standard. They have just successfully completed a whole apartment refurbishment ( inc kitchen and bathrooms) for our nephew. The work was carried out the great care and attention by Dan and his sidekick James -who seem to improve with age! We knew we had to wait nearly a year for a start date ( which speaks volumes for Grosvenors well deserved reputation) but as ever it was worth the wait. It is very comforting to have Fred Dan and James etc working for us and you will too .

We could not recommend Grosvenor Builders enough. From the first meeting with Fred the communication was spot on, the time estimate for the job was accurate as was the initial quote. Dan and James were punctual and very hard workers who were very approachable and had a keen eye for detail. They tidied up at the end of each day and kept the impact of the building work to a minimum. Couldn't be happier with finished refurbishment and we have no hesitation in recommending Fred and his team to family and friends and will definitely be using them in the future.

Having used Grosvenor Builders a couple of years ago for our new bathroom we were happy to wait for a date when they could do our new kitchen and downstairs cloakroom. Again Fred, Dan and James were a pleasure to deal with and they were happy to change plans and make adjustments to give us the best possible result. All work was completed to their usual high standard. Highly recommended.

Fred and the team at Grosvenor Builders have just completed a rear extension for us. We are so pleased with the quality of work and the job finished on time and in budget. Previously we have used Grosvenor Builders to complete our loft conversion; followed by a bathroom conversion. We have the utmost trust in Fred, Dan and Jamie. Their professionalism, quality of work and communication are outstanding. Their Communication is excellent both ahead of the works at pre-planning stage, during the work and at the snagging. This means that we have managed to make good time on our projects and everyone knew what was happening when. When we did our first project, the loft conversion, Fred had been recommended to us. They have now completed three projects in our house and their attention to detail, quality of work and professionalism has continued from the largest job of building the extension to the bathroom refit. Working with Fred, Dan and Jamie has always been a very positive experience for each of our jobs and we wouldn’t work with any other builder.

We had two quotes for this work from Which Trusted Traders. The quotes for labour costs were similar. We chose Grosvenor because the building and plumbing work would all be done by them (no separate builder involved), we liked Fred’s proposals for our difficult upstairs bathroom (narrow, sloping ceiling, cold and damp), and that he pointed out the need for Building Control for the downstairs cloakroom/shower. We are extremely impressed by the skills of Daniel and James who undertook the work. Plumbing, brick laying, plastering, tiling, flooring, carpentry, painting and electrical work were all perfect. They worked carefully ensuring that there was no mess to the rest of the house and always cleared up at the end of the day. They were punctual and reliable and so pleasant to deal with. They were interactive with new suggestions for design improvements and advice as the project progressed. We are delighted with the results. The upstairs bathroom is now a modern bathroom/wet room. The downstairs cloakroom/shower is like a Tardis – shower, toilet and washbasin fitted into an incredibly small space.

Grosvenor Builders carried out the work to a very high standard with good attention to detail. Communication was excellent throughout the project and everyone involved was helpful and pleasant to work with. We are very happy with our new utility/shower room and will definitely ask Grosvenor Builders to return for future projects.

We are really pleased with the cloakroom refurbishment carried out for us bt Grosvenor builders. Fred obviously had a vision of what could be achieved, and it was. James and Dan took care of it all: finding the hot and cold water for the basin, fitting toilet and basin, boxing in and tiling so there are no ugly pipes showing, decorating, lighting, extractor fan and flooring. All done to a very high standard of workmanship and to schedule. I would recommend them.

We had work done by B&Q which turned out to be a living nightmare so needed to find someone to rectify their attempt at a bathroom installation. Fred and the team more than delivered on expectations, with a full bathroom re-fit, reusing as many of the fittings as were salvageable and ensuring the plumbing work was done properly before fitting everything back in. Team were knowledgeable and friendly, with the attention to detail you'd expect from professionals who know what they are doing. Won't hesitate to recommend and are going to be using again for another bathroom and other works

Grosvenor Builders carried out a single-storey extension to our property in 2024, together with a balcony and patio. They were a pleasure to deal with, and it really helped that they fully thought through the various stages required to carry out the extension. Fred and his team were able to dig the foundations, carry out the construction, install the windows, and deal with all the gas, electric and water/drainage requirements with minimal fuss. They completed the job by installing the kitchen and indoor and outdoor flooring and decoration. Dan and James were approachable, kind considerate and attentive to everything needed to complete the job. They were able to provide a temporary kitchen to minimise the inconvenience and this allowed us to live in the property while the work was being done. We would have no hesitation in recommending them or using them again.

Second bathroom refurb for us just completed by the team and another perfectly finished bathroom. The attention to detail and professionalism of the finish is really very impressive and why we're now repeat customers - the small details we wouldn't even think of are taken care of. Dan and James are great, very friendly and professional and couldn't be happier with our bathroom. Will only use these guys for our bathrooms and any major works

Thanks to Dan and James from Grosvenor Builders for doing a great job with our Bathroom. The quality of the workmanship was excellent. We will be back in touch in a couple of years for you to do our Kitchen!

Daniel and James have just completed our kitchen renovation, and we couldn't be happier. Their attention to detail, craftsmanship, solid day's work, and tidiness were impressive. Always happy to explain details or give advice, this made for a trusted and personal experience. The job was completed both on time and as estimated. We would have no hesitation in recommending Grosvenor Builders for any job, large or small.

I couldn’t recommend Grosvenor Builders highly enough. My bathroom started as a total mess and was then made even worse by two lots of cowboy builders. Grosvenor did a fantastic job from start to finish. The lads were friendly and reliable. The attention to detail and quality of work is brilliant, everything looks perfect and works flawlessly. If you want tradespeople you can trust, these are the ones.
