One of the Most Trusted Building Companies in Southampton

Here at Heritage Construction Ltd, we’re proud of what we’ve achieved in our trading history. Established over 20 years ago in Southampton, we’ve grown into reputable house builders whose reach extends out of the city to the Romsey and New Forest areas. Whether it’s basement conversions, loft conversions, house extensions, conservatories or new builds, we live up to our reputation for excellence at every turn. We firmly believe that this is the very least building companies should offer their clients.


Catering to both domestic and commercial clients, we deliver a complete start-to-finish service, from the design stage to the final handover. Unlike other building companies, we encourage ideas and proposals from our clients.


From home refurbishments to base conversions, we are house builders of the belief that property owners in Southampton, Romsey and the New Forest area should see part of themselves in the finished results we produce.

House Builders with Accreditation


We understand that property owners want reliability when it comes to building companies. Thanks to the dedication of our personnel, and the outstanding workmanship we produce, Heritage Construction Ltd proudly carries some the industry’s leading accreditation, including:


National House Building Council (NHBC) – As the UK’s largest provider of new home warranties, the NHBC has helped raise construction standards throughout the country. Our customers in Southampton, Romsey and the New Forest area can rest assured that, as the UK’s single largest approved inspector for Building Regulations, our new builds are completed to the very highest of standards.


NICEIC – The National Inspection Council for Electrical Installation Contracting helps to regulate the training for, and work undertaken by, electrical companies in the UK. This organisation has government approval for Competent Person Schemes. Unlike some building companies, we offer homeowners in Southampton, Romsey and the New Forest area peace of mind when it comes to jobs such as house extensions, loft conversions and basement conversions.


Gas Safe – The Gas Safe Register is the UK’s official gas registration body having replaced CORGI in 2009. The primary intention of Gas Safe remains to protect the public from poor gas work. As fully-accredited members of the Gas Safe Register, our customers can be sure that our gas installations in home refurbishments and renovations comply with nationally set regulations.

On Time & Within Budget


In our role as one of the Southampton, Romsey and New Forest area’s most reputable building companies, we bring projects to completion on time and within budget. We’re able to do this so consistently because we undertake a thorough planning stage with our domestic and commercial clients in which timescales and budgets are set.


We recognise the importance of clear and honest communication to both parties. As homeowners, we understand the frustration when building companies don’t do what they say they’re going to do.


With an extensive network of architects and structural engineers supporting our work, we offer complete project management without relying on any untrusted, untried subcontractors.
