About Trew QS
At Trew QS, we help homeowners take the guesswork out of building costs. Founded by Kevin Trew, our journey began when friends planning home extensions needed expert advice on estimating costs. Word quickly spread, and Trew QS grew organically across the Herts & Essex region—built on trust, transparency, and results.
We offer more than just cost estimates. Our services include:
Collaborating with architects and builders
Planning and managing the works
Negotiating contracts and payments
Whether you're extending your home or starting a new build, we’re here to guide you every step of the way.
Kevin Trew is a Chartered Quantity Surveyor (MRICS) and a Chartered Construction Manager (MCIOB). All services provided by Trew QS are regulated by the Royal Institution of Chartered Surveyors (RICS), ensuring the highest standards of professionalism and integrity.
Our services can save you money, time and stress.
Home owner services
If you’re thinking of altering your home, we provide early advice and cost estimates, before its too late
We can source, appoint and oversea the design teams, ensuring your requirements are met.
We continue to provide cost advice as the design develops, ensuring the design stays within your budget.
This is a key part of the process where our experience saves you money!
We create the pricing documents, liaise with builders, review and compare quotes, ask the right questions and advise you of the most suitable builder to employ.
We can write the building contract, oversea the building works, negotiate changes and pricing with the builder and settle their final account, allowing you to dream about your new home.
