House Extension Costs: A Breakdown

Across the UK, 14% of homeowners are considering making improvements to their home, according to a new study from, and of those 5% have decided to extend their current home rather than move to one that works better for them1.

ExtensionBut the trend is even more obvious among people in retirement or approaching their retirement years. Partly thanks to the new pension freedoms that allow them to take cash out of their pots, if they want to spend it. 

There are many reasons to extend your home, ranging from making space for grandchildren to adding extra facilities to make life a bit easier; like a downstairs bathroom if you need to think about your long-term mobility.

So if you’re planning to extend or improve your home, what kind of costs will you be looking at and what will it mean for the value of your home and your insurance? Here’s our quick guide:


Cost of the average improvements

Okay, the first thing you will want to know is how much this will all cost. Every project is different and the prices will obviously depend on your specific project and the spec you choose. But average prices can provide a decent starting point for budgeting.

Research from Zopa shows the average cost of a conservatory is £5,300, while an extension won’t leave much change from £20,000, with an average cost of £19,750.

Loft conversions come in at a hefty £24,000 on average, while a new bathroom suite costs an average of £4,900. On average, a brand new kitchen will cost £9,6002.


What adds value?

A home is a home and not an investment, so improvements and extensions are about creating a space that works for you. Despite that, most people don’t want to risk spending more on their home than the property will be worth in the future – and certainly not spending money on improvements that add no value.

Nationwide’s Andrew Harvey recently blogged about the best ways to add value to a UK home. He says that adding space via an extension is a key way to add value. “As a rule of thumb, we found that a 10% increase in floor space adds about 5% to the price of a typical house. With that in mind, adding space equivalent to the size of a typical double bedroom to a two-bedroom house can add around 11% to its value.”

He also suggested that a second bathroom can add 5% to the price tag of an average home. But the biggest gains were made with loft conversions or extensions that add an extra double bedroom and bathroom.

“This can add more than a fifth (20%) to the value of a three-bedroom, one bathroom house,” Mr Harvey claimed.

The National Association of Estate Agents recently made some suggestions for home improvements that add the most value to a property without costing much. High on the list was creating the illusion of space by reorganising rooms and chucking clutter, while adding a fresh coat of paint and spending some time managing the garden can also improve value.


What about my home insurance?

If you’re planning a major renovation project then it’s really important to review your home insurance before you start, so that you can check your cover will protect you both during the work and afterwards.

Home improvers should ring and check with their policy provider to make sure that any building work, like scaffolding or removing windows, won’t invalidate their cover, but also to make sure they will still have sufficient cover once the work is finished. After all, if you’ve just added brand new kitchen cabinets and top-grade granite work surfaces to your kitchen then the rebuild cost of your home has just shot up.

And if you’ve extended the house by another room then you’ll probably be filling it with more stuff, meaning you’ll need more contents cover too. So while you’re planning the work and sorting the building regs, don’t forget to make sure your home insurance is sorted too.
