Appraisal Service

How We Can Help

Appraisal Assumptions Report

Love it or not, accurate appraisal is vital to the success of your schemes. So when you need a helping hand or a second glance, why not use our expertise?

Land and Scheme Appraisal

We’ll ‘sense-check’ an appraisal that you’ve done to make sure it’s in line with your strategy and there’s nothing skewing the figures. Or perhaps you have a complex appraisal that’s proving to be a real challenge? No worries, we can do it for you.

On a team level, why not book an online session where we can go through an appraisal to brush up on everyone’s viability skills?

Send us the details

We’ll take a quick look and let you know what’s involved in getting the job done.

This is our most popular service and helps you to optimise your scheme appraisals and remain competitive in your region.

A full review with recommendations

Have your current figures benchmarked against your peers and gain confidence in appraising your schemes for the best possible outcomes. Send us your current assumptions and we’ll provide you with a full review of what you’re using and how it’s affecting your appraisals.

You’ll receive your report with detailed recommendations on the figures you should be applying within your region.

Board Presentation

Once you have your report, we can arrange a follow up presentation to your Board to explain our findings.

Viability Workshops

Unlock the mystery of viability and understand the key factors that impact on your appraisals. After all, it’s not always about the financials!

Bring your team up to speed

When you need anything from a basic introduction, to a refresher for your team, our workshops fit the bill. Sessions range from a half to a full day, and accommodate up to 12 attendees.

Viability Explained - book this one-day session to take your team through the ‘full works’ on development viability.

Cogs and Wheels - this half day session focuses on the key workings of viability and why it needs to be done in the first place.

Best Practice - during this half day session, we’ll demonstrate the do’s and don’ts of completing an appraisal.

New to ProVal? - book this half-day pre-ProVal workshop, which proves very useful in preparing everyone for system training.

What Our Customers Say

“We have now had 2 assumption appraisal reports carried out by SDS, and they have proved very useful in giving us an idea of what others in the sector are doing in relation to their appraisal assumptions. In order for us to remain competitive we have to ensure we are not getting out of sync with the marketplace, and the appraisal assumption report is a really good tool to assist us with this.”
