A construction management practice for West Sussex.
CSQS Ltd is a Worthing-based construction management consultancy serving residential, commercial and mixed-use projects across West Sussex — from Chichester to Crawley, Bognor Regis to East Grinstead, and every town in between. Preconstruction to handover, run by people who write every document themselves.
Full-lifecycle construction management, twelve related services.
We provide the full range of construction consultancy services — from the very first order-of-cost feasibility through cost planning, procurement, contract administration, project management and site management to final account and dispute support. Everything below is delivered by senior people directly. Nothing is subcontracted out to a name you have never met.

Small on purpose. Highly tech-enabled. Written by hand.
Small practice, senior people
We've stayed small deliberately. It means the person you meet at the first call is the person who writes the cost plan, chairs the progress meetings and signs the final certificate. No handover to junior staff, no anonymous team.
Highly tech-enabled
We build our own internal tooling to speed up measurement, cost benchmarking, programme analysis and document production. That efficiency shows up in our turnaround times and in our fees. It never replaces professional judgement — it supports it.
Every document written by us
Cost plans, contract administration correspondence, expert reports, programme analyses — every deliverable is written by the person who did the work. No boilerplate, no offshoring, no generic templates dressed up in a client logo.
Local, and it matters
West Sussex is our home. Coastal exposure at Worthing, heritage constraints at Chichester and Arundel, Gatwick-side supply chain at Crawley, weald clays at Horsham — the county is heterogeneous, and cost planning has to reflect that. Generic UK-average rates hide too much.
Working across West Sussex.
Our office is in Worthing but our work spans the whole of West Sussex — the coastal towns from Bognor Regis through Littlehampton and Shoreham-by-Sea, the market towns of Chichester and Horsham, the commercial centre at Crawley, and the Mid Sussex towns of Burgess Hill, Haywards Heath and East Grinstead.
Founded 2020 in Worthing.
CSQS Ltd was founded in 2020 to provide the kind of construction management practice we wanted to work with as clients — small enough to answer the phone directly, senior enough to be worth calling, and disciplined enough that documents get written when they should.
The practice covers the full construction consultancy spectrum — feasibility, cost planning, project management, contract administration, procurement, employer's agent, principal designer, site management, retrofit, party wall and dispute support. Every service is delivered directly by senior staff.
We work across West Sussex from our Marine Crescent office in Worthing, with active projects throughout the county.
Our approach in one line
"Communication is direct. No preamble, no throat-clearing, no generic language. We write what we know — and we're always happy to pick up the phone."
Talk to us about your project
We answer the phone. We reply to emails. We meet in person across West Sussex — Worthing, Chichester, Horsham, Crawley and everywhere between.
Whether you have a scheme at feasibility, a project going out to tender, a contract that needs administering or a dispute that has already started, the first conversation is free and useful.
