Upsizing costs 44% per room – the cheapest upsizing locations revealed



The latest research by leading estate agent comparison site,, has revealed that on average, every additional room adds 44% to a property’s value. pulls data from all of the major portals which they then cross-reference with the Land Registry using proprietary algorithms to create a comprehensive record of what is selling, where, for how much and how long it’s taking. 

GetAgent’s latest research looks at the number of bedrooms in a property and how much they are currently selling for, as well as the price increase between each threshold and where is home to the most cost-effective up-sizing property markets in the UK.  

The data shows that the average jump in value between each property size is a 44% increase for every additional room.  

The current average cost of a one-bed is £193,226 climbing 26% to an average of £243,762 for a two-bed.  

The popularity of three-bed homes for growing families and a lack of stock to accommodate this demand means that the price jump between a two and three-bed property is one of the largest at 47%, second only to the difference between a four and five-bed home.  

Upsizing between a three and four-bed requires an additional 42% in property prices with the biggest jump predictably that between a four-bed property and a home with five or more bedrooms – a 62% increase.  

With a growing population and a lack of housing stock being delivered, it’s no surprise that the cost of an additional room in London is higher, with an additional 52% required for every room upsized.  

Again, the jump between two and three-bed homes is the second largest at 59%, with an increase of 63% between four-bed homes and properties with five beds or more.

The most and least affordable upsizing locations

However, upsizing doesn’t have to be a tough financial hurdle. There are plenty of pockets of the UK where improving your property potential is pretty cost-effective.

The smallest average increase between the price of a one and two-bed can be found in Blackpool (0.2%), while the most sought-after two to three-bed jump is at its cheapest in Middlesbrough, with a 13% increase.  

While the cost of buying in the borough of Islington is high, it’s home to the smallest increase in property price between a three and four-bed home at just 3%, with Buteshire is the best place to go big and move from a four-bed, to a five-bed or larger, with an increase of 5%.

Founder and CEO of, Colby Short, commented:

“More space is very sought-after resource particularly in the UK’s more built-up areas and as we reach life’s traditional mile markets, such as marriage and kids, many of us will look to upsize in order to accommodate our growing family.

Unfortunately, this comes at a cost with the most expensive jump being the move from a two to a three-bed home. As a result, many are now choosing to expand their current property potential with a renovation or extension, but this might not necessarily add the value expected.  

Yes, an additional room is a plus and will command a higher price, but the reason we see such notable jumps in value between property thresholds is the overall size of a home, the extra bathrooms, the larger garden, the additional space for hosting guests. These are the factors that make a bigger ‘family home’ and command a higher price.”

Flood risk is dampening rental growth as tenants opt for higher ground



Areas, where flooding is more likely to happen, have seen lower rental growth in the past five years, analysis from landlord letting agency Bunk shows.

Bunk looked at areas with a high to medium risk of flooding and how rental growth compares across these areas depending on the severity of the flood risk.

Between 2014 and 2019 areas where more than 30% of postcodes were at a high risk of flooding saw rental growth of 10.71%.

This compares to 12.75% in areas where 20-30% of postcodes are high risk, and 15.26% between 10-20%.

Halifax and Canterbury see low five-year rental growth

With 38.55% of its postcodes being at high risk of flooding, rents in Halifax increased by just 0.78% in the past two years and 1.78% in the past five.

In Canterbury, where 39.93% postcodes are at a high risk of flooding, rental growth has been slow in the past five years at 2.34%. However, they seem to be bouncing back, rising by 8.31% in the past two.

On average, UK rents rose by 11.86% between 2014 and 2019 and 3.54% between 2017 and 2019 – so both Halifax and Canterbury are lagging behind the average in the past five years.

Cambridge and Newcastle on the rise despite the risks

Some areas are seeing very strong rental growth despite flood risks.

Cambridge, for example, saw rental growth of 9.08% in the past two years and a massive 31.16% between 2014 and 2019. 

This is despite having 36.73% of its postcodes in high flood risk areas, as well as 39.90% in medium flood risk areas.

It’s a similar story in Newcastle, where 25.93% of postcodes are at a high risk of flooding.

While rents have grown by a steady 5.91% between 2017 and 2019, in the past five years they’ve soared by 30.60%.

Co-founder of Bunk, Tom Woollard, commented:

“When investing in property you need to do your homework on the area as a whole and not just the local property market. While nature can be unpredictable, buying in an area with a known risk such as flooding can see your financial return wash down the drain as you spend thousands on repairing your property and getting it back to a state that is fit for purpose in the rental market.

Of course, with risk often comes reward and while there is a notable correlation between the risk of flooding and a lower level of rental growth, investing in an area with high tenant demand, such as Cambridge, can still prove lucrative.”
