The services

Four ways to get your project priced

Every project is unique, and so should be your construction estimating solution. Pick the depth that matches the job.

How we charge: We price per element, such as an extension, loft conversion or internal refurbishment. The total cost of your estimate is based on how many elements your project includes.

01

Basic Estimate

£90 flat fee

Next working day

Priced from average square-metre rates for each type of work. We don't analyse the drawings in depth, just the main, obvious parts of the layout, and build the figure as a general summary by build phase rather than itemised task by task. Delivered as a branded, exportable PDF.

Ideal for: Builders who need a quick, reliable ballpark without the cost of a full breakdown.

02

Detailed Estimate

£110–£280

5 working days · fast-track available

A template-driven, per-element estimate built to our standard format. We measure and scale your drawings to pull real quantities, floor areas, door counts, light points and the like wherever they're shown, then price each element against those quantities using our standard material specifications. Covers garage conversions, external works, outbuildings, basements, lofts, extensions, refurbishments and new builds up to 4 bedrooms.

Ideal for: Builders preparing detailed client quotes, contractors managing phased projects, and developers seeking budget clarity.

03

Custom Estimate

£90 per hour

Priced after drawings review

An upgraded Detailed Estimate for projects that go beyond the standard elements. We price the extra tasks that fall outside a normal per-element breakdown and work to your own material specifications wherever you need something specific. We review your drawings first, then agree the scope, price and delivery.

Ideal for: Anyone whose project needs bespoke tasks or materials beyond the standard breakdown.

04

Tender Estimate

£90 per hour

Priced after drawings review

Tailored to the architect's specifications and tender documents, priced against their exact materials and requirements rather than a standard spec. If the architect supplies a pricing spreadsheet, we fill it in line by line, ready to submit. Scope and delivery are agreed individually once we've reviewed the documents.

Ideal for: Contractors bidding competitive tenders who need dependable numbers.

All prices exclude VAT.
