How much does a loft conversion increase the value of my property

On average a loft conversion can increase your property value by around 10% – 20%. That said, this percentage can differ depending on numerous factors, including the loft type, property size, location, features of the conversion and more.

How much does a loft conversion increase the value of your property?

When thinking about extending your property, one of the first things you’re likely to consider is how much it could increase the price of your property by.

As there are so many options available for converting your loft space, there isn’t one simple answer to the question of how much a loft conversion will increase the value of your house, although it’s been known that a loft conversion can add on average around 10% – 20% more to the value of your property.

That said, the percentage could go up or down depending on numerous factors. Some of the key things to consider before going ahead with your project include:

What type of loft conversion you’re adding to your property
The location of your property and its surroundings
What you will be using your loft conversion for
Features of the loft conversion
The cost of the loft conversion vs the increase in value it could offer

What type of loft conversion are you adding to your property?

The type of loft conversion you’re planning will play a huge factor in what value could be added to your home. Not all properties are suitable for all types of loft conversions so it’s always worth speaking to a loft conversion expert to understand what options are available to you before thinking too far ahead.

Where is your property located and what are the surroundings like?

The geographical location will dictate the value increase a loft conversion could offer, as will the properties surroundings and local amenities. Good transport links, highly rated local schools, and a pleasant neighbourhood with a low crime rate are all things considered by most home seekers, so if your property is already based in a sought-after location, you’re likely to see a larger increase in your property’s value after converting your loft than if you’re based in a less desired location.

What will you be using the loft conversion for?

Another factor in what percentage increase you could expect a loft conversion to have on your property is what you’re going to use the loft conversion for. Typically, a converted loft that provides an extra bedroom with an ensuite will add the most value to your home. Home offices are now one of the most in-demand property features since the rise in home working following the Covid-19 pandemic and converting your loft into office space can also offer a significant rise in the value of your property.

What features does your loft conversion have?

Features of the loft conversion will also dictate the extra value you may be able to add to your property. The design and layout of the conversion as well as the additional space created, the décor, available storage in your loft conversion and how you create natural lighting are all things that will play a part.

What return on investment (ROI) could a loft conversion offer?

The cost of your loft conversion and the ROI it could offer will depend largely on the points previously mentioned. Once you’ve considered the points above, it’s advised you speak to a loft conversion specialist to see whether your house is eligible for a loft conversion, and if so, what options are available to you. Once this has been established, a quote can be provided so you know how much the project will cost initially. With this in mind and taking the previous points in to consideration, you should have a good idea on what your return on investment would look like if you were to sell your property. The property market is ever-changing, so its worth noting that the value it could add to your property could go up or down over time.

 Trustindex verifies that the original source of the review is Google. Eddie, our main contractor, and his labourer Damian were an absolute joy to have on-site. Their professionalism, manners, and attention to detail were exceptional. Eddie’s workmanship is top-tier, and the speed and efficiency with which he executed the project were incredibly impressive. We absolutely love our new loft space, and the sheer quality of the construction delivered by Eddie and his brilliant on-site team completely earned this top rating.
If we were judging solely on The Loft Room side, this would have been closer to a 4-star review. Communication with the head office was sometimes a little haphazard, and there were some unexpected plumbing extras from early bathroom decisions that could have been made clearer by sharing an indicative plumbing "extras" cost upfront. We also received some inaccurate guidance from The Loft Room on paint quantities for the new bedroom and en-suite, which left us with far too much paint that couldn't be returned and the "free" decoration incentive was disappointing due to a poor finish and surly decorators.
Ultimately, though, a build is only as good as the person executing it. Eddie’s fantastic management, swift pace, and flawless execution completely outshone other frustrations. We couldn't be happier with the final result.

 Trustindex verifies that the original source of the review is Google. Dragos and his team did a great job for us. They provided a complete end to end service from design, architecture and planning permission, full loft construction and decorating.
Early on in the project, with the support of Dragos, we decided to make a fundamental change to the design. They took this in their stride with no material change to the cost.
The team were considerate, skilled, polite and reliable throughout the project.
I would thoroughly recommend The Loft Room to anyone considering a loft extension or major alteration.

 Trustindex verifies that the original source of the review is Google. From the moment we spoke to Maggie, we felt The Loft Room was the right company for us. The whole admin team (Maggie, Melissa, Helen and Ciara) are warm and friendly, and super efficient.

Dave and Ashley (and Charlie) have done a fantastic job converting our loft. We have wholeheartedly trusted Dave’s expertise with him having completed 42 lofts previously. We are absolutely delighted with the results so far.  The tradespeople that have been over have been excellent: Mark and Kasper - the roofers, Stuart - electrician, Justin - plasterer, Dave - painter etc.

We did get some lower quotes from other companies, but we think there’s a strong case of ‘you get what you pay for’ with The Loft Room. The whole process was surprisingly smooth and unobtrusive - we just hadn’t expected that from a loft conversion. We would definitely recommend The Loft Company.

 Trustindex verifies that the original source of the review is Google. Really happy with the finished loft conversion! The team was very friendly, professional, and respectful of our home throughout the project. While it took a little longer than initially expected, we put it down to the extreme heat of the summer we just had. The quality of the final build makes it well worth it—would recommend!

 Trustindex verifies that the original source of the review is Google. We recently had a rear dormer completed by The Loft Room, which also involved lowering the ceilings throughout the first floor.

The efficiency and quality of the work carried out are the main reasons we’ve given five stars. We felt the administrative and communications side of the process could have been better, but ultimately the most important thing for us was the quality of the build, and in that respect we were extremely happy.

The team on site were excellent and always treated the house as our home rather than simply a building site. They were respectful, tidy and a pleasure to have around throughout the project.

Dragos has been a joy to work with and brought a huge amount of calm, experience and knowledge to the project. Lulian, on site, was the ultimate professional. Nothing was ever too much trouble, and the quality of his workmanship was excellent.

Overall, we’re really pleased with the end result and wouldn’t hesitate to recommend The Loft Room based on the quality of the work and the team we had on site.

 Trustindex verifies that the original source of the review is Google. We are so happy with our new loft space and have been really impressed with The Loft Room from start to finish.

Communication throughout the project has been excellent. Marius and his team worked incredibly hard to meet deadlines while taking great care and pride in their work. Helen in the office, along with Marius, were always on hand to keep us updated on progress and talk us through the different choices and options available.

It was also really helpful having a clear contract in place detailing exactly what was included in the agreed costs. This made budgeting much easier and meant there were no unexpected or surprise costs along the way.

We can’t wait for the final touches to be completed so we can start enjoying our family’s new space. Thank you to the whole team for all your hard work — we’re really happy with the result!

Going the extra mile to make our new space amazing. They really managed to maximise the floor space to create a great sized master bed and en-suite.

From design all the way through to finishing the construction the team have been great. Quality of the work is outstanding, kept informed and updated all throughout the build, and always consulted about the specifics.

Highly recommend.

A huge thank you to Vio, who led the team on our project. Vio and the team’s hard work and dedication has transformed our house. Vio kept everything running on track, maintained a high standard of work, and was always a pleasure to deal with. He and his team treated our home with respect and made sure the details were done right. And also, a special mention to all in the office whose excellent communication kept us in the loop throughout.

We would heartily recommend The Loft Room to anyone looking to do a loft conversion. Thanks guys!
