Most trades businesses at your stage can't respond to every tender opportunity — there simply aren't enough hours. CORE gives you a dedicated estimating function without the overhead of a full-time hire, so your pipeline grows without your workload.
Built for trades, by Trades
CORE works specifically with trades businesses doing domestic works. We understand your project types, your scope, and what your clients expect. That means estimates that actually reflect how your business operates - not a generic template.
No Underpricing
Underpricing is one of the most common growth killers for trades businesses. CORE's estimates are structured to protect your margin - giving you a clear view of cost, markup, and what you need to charge to actually make the job worth doing.
Everything you need
We don't just send you a spreadsheet and leave you to figure it out. CORE delivers a complete pre-construction estimating package - takeoffs, build-up, summary, and supporting documentation - ready to go straight into your tender submission.
Know your numbers
Every estimate we produce is built from a proper takeoff and costed against current material and labour rates. No guessing. No rounding up and hoping. Just clear, accurate figures you can price from with confidence.
Full-time estimator
A decent in-house estimator costs £40k–£55k a year - before NI, pension, and the risk of a bad hire. CORE gives you the same professional capability on a project-by-project basis. You only pay when you need us.
