    Due to the size of our team and the complexity of the build, it was essential to bring an experienced Quantity Surveyor on board to align the costs of the project. Site meetings were chaired by the team at Magnitude and their services have proven invaluable to the project. I would recommend their services, they are professional, conscientious, and flexible, and have added value to the successful delivery of our scheme.

    Eaton Homes

    We recently did a full house renovation including a basement dig, something we have never done before. Martin led us through the whole process from initial costings to final account. I shudder to think what mistakes or over-runs we might have had without Martin’s support. He is excellent: commercial, pleasant to deal with, knowledgeable and laser sharp. If we ever did another project I wouldn’t want to do it without Martin - I couldn’t recommend him more highly.

    Thomas Boszko - Private Client

    We engaged with Martin and his team at Magnitude to act as our Quantity Surveyor on our new build home in Hale. Martin provided an excellent personalised service and ensured that our investment was protected at all stages of the build. He drove value on every package from concept to completion and we were delighted with the service provided.

    John Woosey - Private Client

    A professional, well organised, systemised company who I had the pleasure of dealing with. Martin Trimble the MD is exceptional and the job was delivered on time and in full - and on budget. By engaging these Quantity Surveyors earlier in the process - it made the whole job easier.

    Dave Stevenson - Private Client

    We have worked with Martin and his team for over 10 years. He has assisted us in pricing tenders and post contract quantity surveying services. As a Main Contractor having an independent firm to provide expert pricing and tendering from the outset and assistance during the construction phase has helped our business grow.

    Mike - Managing Director of a Regional Contractor

    Magnitude have always provided me with detailed and accurate pricing, with a fast turnaround. Every member of the team, has always been honest and fair with great customer service. Highly professional, cannot fault their service.

    Opal Construction

    The team at Magnitude continue to provide me with detailed and accurate pricing on my tender returns. The turnaround time is excellent and they are extremely user friendly. Thoroughly recommended.

    Beaumont Construction

    I'm embarking on my first renovation project and therefore was quite unsure what to expect from a QS. Martin Trimble was not only extremely professional and patient but took the time to walk me through the process and gave me some great tips about going to tender with builders. I highly recommend him and the Magnitude team.

    Julie Bishop - Private Client

    We have been using Magnitude for almost a year now, they are very professional, efficient, fair and measured in their approach to managing our project. We have already recommended them and will not hesitate to do so any time in the future.

    Paula Jacobs - Private Client

    Recently embarked on my first ever home building project with a mid-size extension using local builders. Hired Martin's team to do a full review of the quote they did as well as a full cost estimate based on our architect's drawings. Really useful and detailed service, was happy to answer all my extra questions too. Would highly recommend!
