What Is a Reinstatement Cost Assessment (RCA), Really?
Let’s cut through the jargon. Reinstatement Cost Assessments (RCA) are a professional estimate of how much it would cost to completely rebuild your home from scratch – same size, same style, same materials – if disaster struck. Think fire, flood, or structural collapse. It’s not about market value; it’s about the rebuild value.
This figure is what your building insurance valuation should be based on. If it’s too low, you risk being underinsured. Too high? You’re probably overpaying on premiums. Either way, not ideal.
Why Should Homeowners Care About Reinstatement Costs?
Because insurance companies do. And if your home is underinsured, they might invoke something called the Average Clause. Sounds harmless, right? It’s not. This is why accurate Reinstatement Cost Assessments are vital.
What is the Average Clause in Insurance?
The Average Clause is a sneaky little rule that reduces your payout if your property is underinsured. For example:
- Your home’s rebuild cost: £400,000
- You insured it for: £300,000
- A fire causes £100,000 in damage
- Your payout? Only £75,000 (because you were 25% underinsured)
Ouch.
How Are Reinstatement Cost Assessments Done?
A Rebuild Valuation Survey is typically carried out by a chartered surveyor. They’ll assess:
- Property size and layout
- Construction materials
- Location and access
- Listed status or special features
- Outbuildings, garages, boundary walls
They then use industry-standard tools like BCIS (Building Cost Information Service) to calculate a precise rebuild cost.
What people Also Ask About Reinstatement Cost Assessments :
Is a reinstatement cost the same as market value?
Nope. Market value includes land, location, and demand. Reinstatement cost is purely about the cost to rebuild the structure itself.
How often should I get a Reinstatement Cost Assessment?
Experts recommend every 3 to 5 years, or sooner if you’ve renovated, extended, or made major changes.
Can I do it myself?
Technically, yes. But unless you’re a surveyor with access to BCIS data and a deep understanding of construction costs, it’s risky. A DIY guess could leave you underinsured.
Is it mandatory?
Not legally, but many insurers strongly recommend it. Some even require it for high-value homes or listed buildings.
