our story
The Project Estimator story starts with humble beginnings- in a builder’s living room! It very quickly became apparent that there was a huge demand for builder-made estimates. Before long, a partnership with an estimating software company was formed. They employed another three estimators producing quality estimates based on material pricing from a range of quality builder’s merchants, including Jewson and JP Corry.
As the business grew, the relationship with Jewson and JP Corry developed. Our development team was able to adapt the software to use alongside their material lists. This allowed us to deliver a whole new level of detail to our estimates. It was one of many bonuses of using our own in-house developed software.
By unifying our cutting-edge software platform with our now extensive relationship with Jewson and JP Corry, we took the customer experience to new heights. After two years of exponential growth, many millions of pounds worth of materials quantified, and thousands of estimates completed, the business was acquired and reorganised into Build Aviator.
This new chapter formalised our partnership with Jewson & JP Corry, allowing us to exclusively use them for our estimates. This also brought benefits like importing your bespoke account prices and the ability to deal with your favourite branch contacts. It enabled us to offer Executive Pack reports. Eventually, Build Aviator (along with Jewson, JP Corry, and a range of other brands) was acquired by STARK UK Building Materials. With a newly energised demand from the highest level, we rebranded to Project Estimator, to match our name with our service.
From humble beginnings as a one-man band in a living room using estimating software, through to a national presence with exceptionally talented estimators nation-wide, it has been an extraordinary journey. Become part of the journey and contact Project Estimator today.

Your Project Estimator:
At Project Estimator, we understand that there is so much more to pricing up a job than just looking at the drawings, putting a price to it, ordering what you need and setting off to site. Like yourself, we’ve been there and got more than a few t-shirts for our troubles! It’s hours of looking through plans, measuring to quantify every material you need (while checking against specification), and checking that your prices are up to date. When you haven’t even won the work yet!
Does this sound familiar? Now juggle this with regular visits to your builder’s merchant, getting to and from your live site, and tendering for multiple projects. You can see the problem. Where is the time? What this equates to is lots of late nights, weekend work, and missing out on both you-time and family time. If only there was an easier way…
This is where Project Estimator comes in. Our mission: produce the highest standard of Quantity Take-Off estimate, along with an exceptional level of customer service, all while maintaining fast turnaround times. We work to your requirements and aim to be an extension of your business.

By Builders, For Builders:
“By builder, for builders” is the ethos we were built on after Andrew Ellis, our Managing Director and one of our co-founders, looked for a quality estimating service that worked around him, but came up disappointed one too many times.
A true northern brickie through and through, Andrew learned the ropes with the family business while he was still at school. Andrew cut his teeth at sites across the north. He then flew solo at 25 years old.
Starting as a one-man band, Andrew built his own business from the ground up. With time, word of mouth, and a constant drive for excellence, Andrew grew the business into a full turnkey solution. They built up to twenty houses a year across York, Sheffield, Leeds and Harrogate.
