Valuation of flats based on ‘average prices’ – what you need to know

Reinstatement cost assessments for flats, average value vs. actual value.

It is rare that two blocks of flats look the same externally and almost impossible for the internal lay out and finishes to be the same. So why would they be valued identically using average rates?

We are often asked why our Reinstatement Cost Assessments (method to provide a valuation of flats) may differ from an ‘average’ price found on search engines, Building Cost Information Service (BCIS) or The Association of British Insurers (ABI) guides.

It is rare that two blocks of flats look the same externally and almost impossible for the internal lay out and finishes to be the same. So why would they be valued identically using average rates?

Here are 4 common factors that affect the valuation of flats:

Structural masonry vs steel impact value of flats
Structural masonry vs steel can have a huge impact on cost.

1.Building Construction

Everyone can appreciate that there is a difference in rebuild cost between a modern and a period built property, however the building pathology itself is often overlooked. Each block of flats is unique and, in order to reach an accurate, RICS compliant, Reinstatement Cost Assessment (RCA), needs to be valued on an element-by-element basis.

The use of structural masonry versus steel frame on modern buildings for example can have a huge impact on cost. In the case of the external walls, examples of the range of finish can be seen from modular cladding with a rendered finish, to heavily glazed or with marble cladding.

These materials range significantly in value, ease of procurement and installation time – therefore impacting on the RCA; these details would be neglected in an insurance valuation based on average rates.

Surface finishes affect the insurance value of property
Surface finishes will affect the insurance value.

2.Level of fit out and specification

Floor finishes, wall finishes, quality of fitted storage and indeed specification of kitchens and bathrooms can vary hugely from development to development.

The value of kitchens in particular can differ significantly, with integrated white goods and appliances being included within a buildings valuation and non-integrated white goods considered a contents item and therefore should be excluded. It’s imperative the quality of these kitchens and their inclusions are accurately valued.

For example, kitchens have a large value range with a small kitchen with chipboard units and a laminate work surface having a far lower value than a bespoke hardwood kitchen with granite or high specification resin composite work surfaces, irrespective of whether their size is comparable.

All of these items would be reinstated in the event of a total loss and therefore have to be included in the RCA in order for the property to be accurately insured.

The value of a flats will be affected by any historic and non-standard finishes
Historic and non-standard finishes have to be allowed for.

3.Professional Fees

Using listed properties as an example, a variety of professionals would be required to ensure its reinstatement is approved by the planning authorities. Other elements such as conservation areas can also increase the fees required compared to a modern, modular new build without these influences.

Non-standard finishes requiring specialist trades can have equal impact to the RCA and the potential requirement of archaeologists, botanists and ecologists for factors not present during initial construction all have to be allowed for.

External items should be included for an insurance valuation for blocks of flats
All external items should be accounted for.

4.Externals

‘Externals’ include all items which are necessary and part of the development but fall outside the external walls of the main building. Examples include: mains utility connections and drainage, parking and bin stores. We have also come across tennis courts, bridges and historic cranes.

It’s imperative all such items are accurately accounted for within the RCA valuation with the rate of tarmac site roads being far lower than block paving. Items of larger impact can include structures such as garages and general stores, electricity substation housing and boundary markers.

Boundary walls and walls within the curtilage are also to be included, with a stone wall costing more than brick and retaining walls, be they sheet metal piled, concrete, brick or boulder, all influencing the final valuation.

Factors such as site access and waste management will all affect the valuation of flats
Factors such as site access and waste management will all affect the valuation

5.Site Factors

The RCA needs to be tailored to each specific site. Access, working area for site welfare facilities, waste management and general storage all influence the rebuild cost.

On sites with restricted access relevant permissions must be obtained from surrounding landowners. These can come with financial implications but can also delay the programme of reinstatement, incurring further costs.

Valuation of Flats – Conclusion

To conclude, a number of factors beyond the basic building fabric must be taken into account to reach the correct reinstatement cost for insurance purposes. An assessment based on element cost approach valuation is as unique as the property being assessed.

An assessment based on average prices often doesn’t offer the detail required to get it right!

The valuation of buildings within prime Central London

Reconstruction costs in prime central London locations.

Reconstruction costs within Prime Central London far exceeds any published data.

As valuers of property all over the United Kingdom, our experience in the last 12 – 24 months is that reconstruction costs within Prime Central London, as defined by the postcodes below, far exceeds any published data.


This paper is intended to alert underwriters, brokers, managing agents and property owners to possible underinsurance that will be sitting within these locations.

The current position

The increase in market values in PCL is widely acknowledged with comments being used such as ‘the market’s gone crazy’, ‘prices are rocketing etc.’. There has been a lot of comment in the press with regard to the purchase of property within PCL being seen as a safe haven for foreign investors during the last few years. All brokers/ underwriters will recognise owners of property and homes in these locations fitting that profile.

Knight Frank has been tracking this since 1976 and although the trend in 2013 has been slower than some previous years, growth over the last 3 years has far outstripped that in other parts of the country.

Although it still remains the case that there is no correlation between market value and rebuild costs/the building sum insured, it stands to reason that a contractor working in a home that has just cost £15,000,000 to purchase – or indeed £1,000,000 – is not going to charge £50 to fix a dripping tap.

The cost of employing reputable contractors in these locations has increased. The market values have increased far beyond any indexing applied to an insurance policy and, while again we would not want to make any firm correlation between market and insurance value, one does need to dig a bit deeper as to what is going on on the ground.

The profile of the client has to be considered. The process required to create a perfect and flawless finish and the expected ‘scope creep’ of a design scheme, does take longer to achieve and inevitably contractors price this into their fees.

Scope creep and technology in buildings.

The technology found in such buildings is also increasing. It is not uncommon for a quarter of the sum insured to be taken up by lighting, heating, air conditioning, audio/visual installations etc. It is worth noting that in a standard office building, the inclusion of full air-conditioning (a must have in some quarters now) can add 20% to the rebuild cost.

We have assessed flats where clients have paid £8,000 per m² of floor area just for the internal fit out. There are also cases where a simple refurbishment of a PCL townhouse in a very sedate – one may even say ‘ordinary’ HNW scheme – has cost £7,000 per m². Internal fit outs of some commercial spaces – again with a fairly calm, simple scheme – have come in at £11,000 per m².

One BCH client reports spending £5,000,000 on a reception hall/ lobby scheme. Anecdotally there seems to be an element of “keeping up with the Joneses” with clients wanting to outspend their competitors or neighbours.

Carrying out a rebuild in a very tight/compact location and managing a project around restricted working practices and hours enforced by local authorities and planning bodies, also have a severe impact on the amount charged and the length projects take to complete. While some of the above may seem not to be relevant to insurance, there is an assumption that insurers have deep pockets and that claims are simply ‘expensive’ and the cost of the unexpected seems to have become the norm.

Re-valuation of buildings – the most prudent response.

Attention is drawn to the need to re-assess the base sum insured on a regular basis. Good practice advises that this is dealt with by way of a desktop update on an annual basis, with a full re-assessment undertaken in every third year. A full assessment also needs to be prepared in the event of substantial alterations being undertaken to the property.

Royal Institute of Chartered Surveyors
The above is the official guidance given on this matter by the RICS. However, very very few organisations carry out an annual review or even a three year review. Most owners and organisations leave it for at least five years. It is our opinion that for properties in PCL, the desktop update for those assessed during 2012 and those assessed on the basis of a site visit during 2010 or before should now be marked as an URGENT PRIORITY.

To conclude

Taking all this into consideration, BCH has revisited its view on costs within the PCL postcodes and is now adding significant contingency to reflect the increased costs compared to other parts of the UK. We would urge that desktop updates or full revisits be requested (depending on the date of the original assessment) to take into account what we see as a key market shift. This is essential to protect not only policyholders but also insurers; especially those offering any type of guaranteed rebuild cost where effectively the sum insured is unlimited.
