Home Insurance Premiums: Size and Location’s Impact
The cost of home insurance is influenced by many factors, but recent research reveals that the size and location of your property play the most significant roles in determining premium prices. According to a 2025 study by Go.Compare, the number of bedrooms in a home and its geographical location have the most substantial impact on insurance costs.
Property Size: The Primary Driver
The number of bedrooms a property has is a crucial factor, with the average home insurance policy price varying by as much as £243 due to this detail. Go.Compare’s analysis showed that, on average, the number of bedrooms can impact premiums by £121. Given the average rebuild costs and the value of possible contents, this is a significant factor when assessing the risks and costs of the property.
Location Matters, Too
Following property size, location emerged as the next most significant influence on the price of home insurance. The region in which a property is situated affects home insurance prices by an average of £119, only £2 less than the impact of the number of bedrooms, the analysis revealed. Location-based variations in the median policy price can be as high as £230, reflecting differences in local risk factors like crime rates and flood zones.
Other Influential Factors
Roof type also plays a notable role in determining premiums, with median prices varying by up to £163 depending on the material used, resulting in an average impact of £82. Homeowners also have some control over factors that affect their premiums. Lock type, for instance, can impact premiums by an average of £43 and up to £82 in some cases.
Interestingly, property type had a minimal effect. The median price only changed by an average of £2.50 regardless of whether the policyholder lived in a flat, house, or bungalow. The time of day the home is usually occupied also had a minor impact, at an average difference of just £10.
Expert Insight
Nathan Blackler, a home insurance expert at Go.Compare, commented on the findings:
It’s well known that certain things can affect the price you’re given for your home insurance, but it’s really helpful to see which of these have the biggest impact and in what way they influence your premiums.
Bigger properties have higher rebuild costs and usually more possessions, so the effect on your price is pretty significant.
Meanwhile, some areas have higher house prices or see more claims due to crime and floods, which can also push up prices. On the other hand, using better locks and building materials can reduce the likelihood of a claim and bring premiums down.
So, before moving or altering your home, it’s worth comparing policies to see how it might affect your premium and take any changes into account in your budget. This applies if you’re doing something like changing the type of lock on your front door. Look at which ones offer the biggest changes in your premiums before getting them fitted.
