In order for us to provide you with a space test result for your new home, we will need the following information: plans, elevations, U-value requirement for external walls if known (if not known then consider whether you would like your walls to perform well, better, or best – this will give us a good guide to work from). We will return your space gain result within 2 working days and will even estimate how much extra your new home may be worth, as a result of this additional space. We will aim to get your space test back to you within 2 working days.
