Munro Waterston

"I have worked with Ronnoco Building Services for over five years and during that time they have been appointed to carry out various works for differing clients: while having the capabilities to undertake a wide range of skills themselves, they also have access to specialist sub-contractors who can be call upon to assist when necessary. They recently finish a differcult conversion in Hampstead including general improvements to upgrade the property (structural alterations, rationalisation of electrical, plumbing and heating services, replacing windows, works associated in installing a new kitchen, underfloor heating, floor and wall tiling, decorations, etc) Particular attention is attached to providing high standards of service and workmanship together with a willingness to achieving satisfaction. Throughout care and consideration is given when involved in contracts in occupation during progress of the works: importance is attached to establishing a good working relationship with the Clients and finally to arriving at a fair and reasonable settlement on costings. They have always been found to be honest, conscientious, reliable. They take an interest in in the particular project and are prepared to make contributions to its success.The building industry is in need of those who still take the same pride in their work. I have no hesitation in recommending them.

Mrs. O’Donogue

"Ronnoco Building Services Ltd assisted us with our planning application and building control to build a New Dwelling. From start to finish they have been great, helping us with the planning and design of our new home, which we are delighted with. The detail in their work and finishing has been the best Contracting Company we have ever dealt with. Their deadlines were met at each stage of our project and communication with the Project Manager was amazing.All of their staff were very punctual, friendly and accommodating. I would highly recommend this company."

Brentwood Essex

Emmanual School

"We have used Ronnoco Building Services Ltd for the past 5 years for various building development projects at Emmanuel CE School as well as maintenance and up keep of our facilities. They have been very reliable with regards to timescale of the projects which they have carried out for us, this is paramount for the school that projects are finished on time to a high standard so that it does not impact on our pupils. Paul has always gone out of his way to accommodate the schools needs and is very reassuring and easy to work with. Whether it is out of hours call outs or a random call for advice on materials, fixtures and fittings he is always happy to help. Given our past experiences with local tradesman Ronnoco Building Services Ltd are a pleasure to work with and we would recommend them without hesitation."


Mr. Buckhust

"It was a pleasure dealing with Ronnoco from the prompt and detailed initial quotation through to on-time completion. Unusually for this industry, communication was excellent throughout the job with 24/7 phone access and prompt replies to e-mails. Materials were delivered in a timely manner and Paul and his colleagues were a pleasure to deal with throughout the 6 week period. The site was kept tidy and left in perfect condition (even with windows cleaned and gutters cleared out). Perhaps not the cheapest, but amongst the best service and quality I have experienced for a long time."


Mrs. Potter

"From start to finish Ronnoco Building Services Ltd have been professional and their standard of work is exceptional. The perfection of their work, their time-management and their professionalism through our project has been by far the best Contracting Company I have ever dealt with. Their attention to detail and their finishing of the work has now given us a beautiful home, I would highly recommend Ronnoco Building Services Ltd to anyone I speak to. All of their Team were friendly and always took great care of our home, always tidy and respected our house at all times."

Ongar Essex

Mr. & Mrs. Best

"My wife and I Ronnoco Building - to carry out three pieces of work for us over a period of about 4 years. The repeat work I think speaks for itself, but I will say anyway that we are always pleased with the quality of their work, their tidiness and polite approach with us and our children. They also respect the household and put protection down and around the working areas.

"We have had some external work (drainage and rendering) and two full bathroom renovations. Not simply refits. As ever with construction work there were changes and surprises, all of which were dealt with quickly, and always at a fair price where applicable. I also have found their advice useful when we have discussed proposals and whilst we haven't always agreed, it has helped us be clearer about options and ultimately be happy with the final choices.

"A fourth piece of work was an emergency call out to repair a broken shower screen - a fair price and a very quick response was hugely appreciated.

"Should the need arise, we will certainly be approaching them again for future work.

"Thank you.


Caroline Holdaway

"It was a pleasure to work with Ronnoco Building Services on a project last year in Aubrey Walk. It was a complete refurbishment of a three storey Town House. They went out of their way to ensure the work was carried out in a timely, tidy and professional manner. Their pricing was realistic and their extra costs were humane. The are technically extremely competent with impressive project management skills, and the project was completed on time, to budget and to the satisfaction of both myself and my client.

As a main Contractor the team are extremely honest, reliable and hard working. I would have no hesitation in either recommending them or indeed embarking on a further project with them again in, the future.
