outsourced estimating

Unlock hours back in your week with professional construction estimating, delivered without the cost or overhead of a full-time in-house quantity surveyor. Our experienced estimators handle your take-offs, bills of quantities and priced proposals for you — from single-storey extensions to full new-builds — so you spend less time buried in spreadsheets and more time running your sites.

If you're tendering anywhere in the UK and don't have the capacity to price every job properly, outsourced estimating is a fast, fixed-fee way to protect your margin without slowing down your pipeline. Most estimates are turned around in days, not weeks.

We had Sam price a fairly big extension for us and the communication was second to none, was no issue making amendments and was fairly priced to with a quick turn around. Will certainly be using again.

Brett C

Sam at Core is professional and reliable and I would trust for all estimating requirements.

Matt S

Great experience with core had a couple projects estimated which resulted in our favour. Highly recommended will continue to use for any project estimating big or small. Five stars.

Jay C

Super reliable team and super accurate feasibility estimates. The team are easy to deal with and answer any questions asked (even stupid ones). Would highly recommend if you want to know what your extension will cost before finalising expensive architectural designs.

Sam H

Very professional service, prompt and pleasant. Know what they are talking about and are very cooperative. They do countless jobs for me a month and can work with me at every scale, great company, highly recommend!

James K

After using cores services I cannot recommend them enough. They were very professional and efficient. Their team communicated clearly, provided detailed estimates, and delivered everything right on time. I felt confident in their expertise and would highly recommend their services.

Verity C

Sam did an electrical takeoff for me for a large luxury development. Super fast turn around and got it spot on, I would recommend. Worth the investment.
