As with many services and physical products, the more you purchase the bigger the discounts. This applies equally to commercial property insurance as with most other financial service products.
What this means is that if you approach a single insurer and ask them for a quote on one property, for example a £250,000 shop in Manchester, they may give you a price of £450.00, inclusive of the insurance premium tax. There are many differing factors, such as location, construction, claims and of course type of occupancy that affect premiums, amongst others, but stay with me for a minute or two. Now, let’s assume that you have 9 other, more or less identical buildings in similar rating areas throughout the country. Now, instead of paying 10 x £450 = £4,500, you may only pay £3,500 to £4,000 as the commercial insurance companies are so keen to get in (good) business nowadays that they will offer discounts of up to 25% in some cases. This is all well and good and could represent a saving for you. To give yourself the best chance of getting the double of good premium and good cover, then you need to speak to an independent business insurance broker. They understand what every single insurer is looking for at any one particular time. So, rather than looking for that needle in the haystack yourself, get an expert to do it for you.
But, you do need to be cautious as this is not always the best way of getting the right price. Most insurers prefer their own different types of business, there may be a few that want the same things, but across the board you will not find a single insurer that is happy with all risks. For example, you may find an insurer that likes low risk property owners, ie offices, shops etc. So, you can give them 1o risks of this type and get yourself the nice big discounts. However, if one of the risks happens to be a fast food takeaway, you may find that that one insurer charges three or four times the market rate.
Keeping all your cover with one insurer does not make sense if you have a varied portfolio. As a broker, we prefer to look around for each and every risk presented to us, unless the type of risk is the same (ie residential lets – professional tenants), we will never automatically place all the risks with one insurer. This is lazy and never the right way.
