The practice

Between the survey and the decision.

Independent construction cost advice for the repairs a property needs and the improvements you want to make.

Cost Before Keys combines modern software with professional construction cost judgement. Our technology gathers and organises the information; a cost professional prepares and approves every budget.

We are independent. We don't sell building work, take commission from agents or provide valuations.

Cost Before Keys is a trading style of Builder Standard Limited, registered company no. 17452211.

What we are not

  • • Not a RICS Home Survey or valuation
  • • Not structural design
  • • Not a fixed-price building quotation

For property professionals

The financial context
beside your advice.

For RICS surveyors, independent buying agents, estate agents, mortgage brokers and property solicitors: independent construction cost advice to complement your client’s survey and purchase decisions. We do not replace surveys or specialist inspections, value property, or promise a seller will reduce their price.
