Unlocking the Essentials of Reinstatement Cost Assessment: A Guide for UK Property Owners

Updated: May 4

Imagine you've insured your property for an amount significantly lower than the rebuild cost. A disaster strikes, and the damages are extensive. Suddenly, you're faced with the reality that your insurance payout won't cover the full cost of rebuilding. This scenario, which could have devastating financial consequences, highlights the critical importance of a reinstatement cost assessment (RCA).

Understanding an RCA: What is Reinstatement Cost Assessment

A reinstatement cost assessment (RCA), also known as a rebuild cost assessment tells you how much money you'd need to rebuild a property if something bad happens; taking into account all the nitty-gritty details such as material, labour, and even cleaning up the mess after a fire or natural disaster, for example. This assessment is important for property owners in the UK because it ensures you don't have too much or too little insurance. Let's dig into why that matters.

There are two main reasons to have an accurate and reliable RCA:

  1. The law says property owners must have the right insurance to cover a rebuild. Without it, there can be legal implications such as being liable for negligence.

  2. Beyond the law, an RCA helps you sleep at night. If something happens, you know you'll have the cash to fix it or rebuild it.

Understanding why you need an RCA is one thing, but getting a handle on the process and what it means is another. In the next section, we break it all down for you.

The Reinstatement Cost Assessment Process

Let's take a closer look at how an RCA works, so you can understand why it's a big deal for property owners.

Initial Assessment: What Happens First

First, we gather details like where the property is, how big it is, what it's made of, and more. This sets the stage for the whole assessment. We can do this in two ways: One is done online using a mix of complex formulas and our own expertise, and the other is by visiting your property in person.

Data Collection: Gathering Property Specifics

After the first assessment, we get down to gathering lots of info about your property. This includes details about how it's built, any unique or notable features, and what shape it's in. We might also need to see your building plans and other documents. The more info we gather, the more accurate the assessment.

Cost Estimation: How Costs Are Calculated

Once we have all the data, it's time for some number crunching. We calculate how much it would cost to rebuild your property. We consider things like:

  • Construction costs

  • Property size and complexity

  • Age and condition

  • Materials used

  • Special features

  • Location

  • Regulations

  • Inflation

This helps us come up with a total cost.

Final Report: What It Contains

The final report shows you how we came up with the cost to rebuild your property. Understanding this report helps you make smart choices about your property insurance. You can take a look at a sample report here.

Be Prepared: Keeping RCA Costs Down

Just like managing insurance and property rates, reinstatement costs are another expense to consider when you own a property. While RICS (Royal Institution of Chartered Surveyors) recommends a comprehensive property assessment every three years, it's best to make yearly adjustments to account for factors like inflation. In theory, this could mean having to have an RCA completed every single year. Ouch!

Fortunately, there are steps you can take to get ready for the reinstatement cost assessment (RCA) while also controlling costs. Firstly, maintaining precise records of renovations and improvements is helpful. This documentation streamlines the RCA process, minimising both hassle and expenses.

Next, consider our desktop assessment option. Using cutting-edge tech and data, our experts can provide you with an accurate RCA online, at a much lower price than an on-site visit.

What the Law Says About Reinstatement Cost Assessment

While not mandatory in the UK, RCAs are essential for complying with the Insurance Contracts Act 1984, which requires accurate property information for insurance. Having an accurate RCA ensures you're not only meeting your legal responsibilities as a property owner but also securing your own peace of mind.

Choosing an RCA Provider

Selecting the right assessor for your reinstatement cost assessment (RCA) is crucial, to guarantee not only the accuracy of your assessment, but that it adheres to industry standards and regulations. To make a well-informed choice, consider factors such as professional qualifications, experience, compliance with industry guidelines from RICS, the use of modern technology and reliable data sources like BCIS, client feedback, transparent pricing, local knowledge, and industry connections. If you can’t find this information on their website, they might not be a reliable assessor.

Let’s delve into some real-life examples of why choosing the right provider, and the right method of assessment, are so important.

Reinstatement Cost Assessment Real-Life Scenarios

To show how reinstatement cost assessment plays out in the real world, let's look at three cases that highlight the importance of accurate insurance coverage:

Susan's Property in Brighton

Susan owns a property in Brighton, where property costs are high, and many owners don’t understand the difference between market value and reinstatement cost. Initially, Susan relied on a free online calculator that suggested the property should be insured for £1.2 million. But, concerned about potential underinsurance after hearing about the pitfalls of the ‘average clause’ in insurance, Susan decided to book a desktop assessment with This assessment revealed that her property's actual rebuild cost would be around £1.8 million. Thankfully, Susan learned not to rely solely on online calculators before it was too late.

John's Block of Flats

Meet John, a property owner who oversees a block of flats valued at £16 million. Recognising the complexity of his property and that a desktop assessment might not be adequate, John opted for a comprehensive on-site survey. The survey confirmed that John's property was indeed insured for the correct amount, providing him with peace of mind. For more complex properties, an on-site assessment is always advised, to help you (and John) sleep better at night.

Residential Care Home Conversion

Picture a residential care home that was once a hotel, featuring seven bedrooms and valued at £7 million. The owners recently undertook a significant conversion of the property, prompting them to consider a reinstatement cost assessment (RCA). They initially approached a local surveyor who estimated that a site-based RCA would cost around £1,500 to £2,000.

Seeking a more cost-effective solution, the owners opted for a desktop assessment. The assessment revealed an overinsurance of approximately £500,000. Catching this overestimate resulted in reduced premium costs over the years – nice! It's worth noting that hospices and care homes are among the top 10 underinsured building types (read more about it in our recent blog post).

These cases emphasise the importance of choosing the right assessment method based on your property’s complexity, location, and more.
