HBXL Estimating Service

Building estimates for UK construction firms

HBXL Estimating Service prepares building estimates and quotations for extensions, conversions, new builds and housing developments. Its clients are builders, developers, architects and builders merchants, and the company states it has customers throughout the UK. The service is aimed at firms with a backlog of quotes, a difficult job to price, or those considering outsourcing estimating work.

The published starting figure is £129+VAT, with a fast turnaround. The process begins when a client submits plans and elevations; the company then returns a delivery date and a fixed-price quotation for completing the estimate and quotation.

How the estimating work is organised

Each estimate is handled by a single estimator who stays with the job from start to finish. According to the company, the plans are examined in detail and priced using a broad choice of materials prices drawn from across the UK, rather than being tied to one merchant. The estimate pack also includes management documents such as material order schedules and build programmes.

The company presents its method as a set of commitments. It states that it takes the time needed to get the job right, assigns one estimator per quote, raises queries with the client, uses prices from multiple merchants and sticks to the timeline. It also states what it does not do: it does not incentivise staff to rush jobs, does not use more than one estimator on a quote, does not make a large number of assumptions, does not rely on a single merchant's prices and does not let deadlines slip. The site claims a 100% record of hitting deadlines.

What the estimate pack contains

Beyond the priced estimate and quotation, the pack includes personalised management documents, material order schedules and build programmes. The company also indicates that an estimate pack comes with a free set of 3D images, subject to terms and conditions. Its calculators are described as quantifying everything and incorporating the client's mark-up, and the output is intended to give customers detailed quotes and cost breakdowns with graphics they can show to their own clients.

Arguments the company makes for outsourcing

The site frames the service around several practical benefits: producing detailed, professional-looking quotes that help win work and satisfy lenders; freeing owners from evening and weekend quoting; avoiding exposure to price rises through regularly price-checked materials; and protecting margin through complete quantification. It also publishes guidance content on related topics, including the difference between allowances, PC sums, provisional sums and contingencies, and the limits of AI for producing construction estimates.

Customers and company background

The site lists separate user paths for builders, homeowners and self-builders, architects and designers, and merchants. It includes testimonials from a self-builder, a private customer and a building firm, praising the estimator's knowledge, patience and responsiveness.
