Terry brings huge experience to his role as our Building Director. His ability to manage a project from start to finish, on time and on budget is second to none.

They are a multitude of windows and doors suppliers available on the market today. However, we only use a selected number of tried and tested partners for our customer renovations. We are also an accredited member of Certass. Certass is a government authorised to operate a Competent Person Scheme and is a UKAS accredited Certification Body).

Member companies are assessed inline with the standards laid down in EN17065 and specific license requirements of MHCLG, TrustMark, PAS2030 or Certass. This means that Certass financially and technically assesses its members to ensure they meet required standards.

In addition, to initially assessing every member each year, Certass will inspect a sample of work submitted by the member for scheme compliance. Where appropriate, Certass notifies the local authority and issues a Building Regulation Compliance Certificate to the homeowner.

  • I cannot speak highly enough of Lewis, Terry and the Sovereign team. They completed our works to a fantastic standard and in a timely manner. It is very clear that they care more about doing a great job than profit margins and are very aware that they are in your home. They found an additional issue with our existing roof which was missed by our architects and solved the problem at minimal cost to ourselves. I would not hesitate to recommend the Sovereign team to anyone looking to conduct home improvements, large or small!

    Mr. Jewiss, Brentwood - April 2019

  • Me and my husband are absolutely over the moon by the work Sovereign has done for us. They were on site almost every day. The guys were really good, friendly and professional. They worked really hard especially as access was difficult and there was a lot of concrete to be removed. Terry and Lewis were on site as much as was needed and always at the end of the phone if needed. The extension was built quicker than expected and done exactly how we wanted it to look. The kitchen looks amazing and installed in just over a week, we had no problems and again exactly how we wanted it to look.”
