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.
