Main Contractors
At CORE, we plug into construction teams who actually give a sh*t and need an estimating partner that works as hard as they do.
The Problem: Inaccurate Cost Plans and Rushed Estimating
Main contractors across the UK are under pressure to submit fixed-price tenders on short notice, often with incomplete drawings and vague specifications. Without proper construction estimating services, you’re left relying on guesswork, outdated spreadsheets, and incomplete subbie quotes. The result? Budget overruns, unrealistic timelines, and constant stress trying to fix problems that started before you even broke ground.
The Reality: Good Builders, No Time for Paperwork
Most contractors are brilliant on site - but not everyone has the time or technical skills to accurately and efficiently price every job. Estimating takes time away from running your projects, managing your team, and winning the next bit of work. And when you do ask for help? You often get back generic, spreadsheet-based estimates that are unusable - no subcontractor prices, brief clarifications, and no backup if things go wrong. We’ve been there.
The Risk: Margin Loss, Admin Overload, and Stress
The construction industry has some of the highest levels of administration of any sector — and most of it starts with poor estimating. Rushed pre-construction planning leads to constant rework, missed procurement windows, and unreliable cashflows. If the job isn’t properly costed and scoped from the start, you’re stuck chasing problems for the rest of the project.
The Solution: Tailored Pre-Construction Support for Main Contractors
At CORE, we’re not just a construction estimating company — we’re a pre-con team built by contractors, for contractors. Because we’ve lived the same pain, we know exactly what you need. We deliver:
Trade-ready estimates that reflect real UK construction costs
Subcontractor packages sent out and chased — so you don’t have to
Cost planning that factors in buildability, scope, and market conditions
Feasibility reviews to flag design risks and save costs early
Everything we do is designed around how you actually build.
The Result: Win More Work, Deliver With Confidence
By plugging CORE into your business, you get the benefits of an in-house estimating team — without the overhead. You’ll win more tenders, reduce risk, and keep margins protected with pricing that makes sense from the first day on site. We take care of the pre-construction stress so you can focus on delivery.
