Are you thinking about a loft conversion? Would you like to know how much it typically costs? During the summer of 2016, we sent out quote requests to specialist loft conversion companies in the south of the United Kingdom. The figures we have published on this page are based on that research.
What’s Included in the Price? (read this first – every quote is the same)
Here is a list of everything that we wanted to be included in our loft conversion cost, we made sure it was included in the written quotes we received.:
If you are comparing your own quotes to the ones we received, please double check that they are comparable::
- Electrics including smoke alarms, lighting, sockets and a power shower. (we supply, they install)
- Plumbing – shower, hot, cold water and waste. (we supply bathroom equipment, they install)
- Heating – extra radiators.
- Insulation to walls and roof as required by regulations.
- Floor tiling and/or carpets (we supply, they install)
- Painting and decorating.
- Skip hire.
- Labour included.
Will You Pay More or Less Than Our Quoted Price?
Several of our chosen companies explained that our loft would be easy to work on as there was adequate headroom and the location of our shower/toilet was directly above the existing bathroom so very little extra plumbing was required. So expect to pay more if this isn’t the case with your property.
The dormer roof on our conversion will also be a flat felted roof, these are cheaper than tiled pitched roofs.
Also, the quote includes the labour to install the flooring throughout, bathroom tiles, shower unit, power shower and toilet in an en suite. But we will be paying for the items ourselves so that is an extra cost.
Our street also has several houses with the same type of loft conversion, so we believe that planning permission is not an issue for our house. This may not be the same for your property, so you may need to budget extra for this.
What is Quotation Check?
Quotation Check was launched in 2014 with the aim of casting light onto the prices charged by tradespeople and businesses in the home improvement sector.
To date, we have researched over 100 prices and published our findings on this site.
Up until now, we have avoided researching the cost of larger projects due to the variables and endless choices. However, due to several requests from visitors to this site, we decided to investigate average loft conversion prices in the UK. We used a property in Camberley, Surrey for our price guide.
Loft Conversion Cost – An Average of the Prices we Received
We contacted eleven loft conversion companies and asked them to provide us with written quotes or estimates for a loft conversion to our two bedroom semi-detached property in Camberley, Surrey.
Only nine responded and visited us.
The figures below are for a small double bedroom with en-suite shower unit and toilet. As you can see from the table below, the average loft conversion cost is £31000.

|South, SW and Midlands||N/A||£31000|
|Outer Region and North||N/A||N/A|
How do our Prices Compare to Others?
The price checking service Which? suggests a price of £21400 for a loft conversion with no dormer but 4 roof windows and a price of £29000 for one with a dormer and one window. Both prices are less than ours but theirs does not include the cost of the shower and toilet while ours does include the labour fee for such extras.
One of our friends recently had a one bedroom with en-suite loft conversion built on a property in west London and the final price was £47000.
We have also received an email from a visitor located in Kent who sourced three loft conversion quotes (small room with en suite) and the cheapest was £38000.
This just emphasises how important it is to gather your own quotes. Every loft is indeed different and prices will vary by a considerable amount.

We think our research is very insightful, but as every loft is different, it really isn’t a substitute for a custom quote.
The chances are that the specifications of your roof will be different to ours and the prices you receive could be very different indeed.

The loft we wanted quoted for is located on a two-bedroom semi-detached property. It will require the construction of a dormer to the rear side of the roof and two small roof windows to the opposite side.
We wanted one small double bedroom with an en-suite inc shower unit.
It’s important to understand that there are several different types of loft construction:
- Roof windows but no dormer – good light penetration but compromises on size/space. These are usually the cheapest.
- Roof windows and dormer – extra space/headroom and extra light through roof windows.
- Dormers but no roof windows – maximum possible space but also more expensive.
Roof windows are secured at the same angle of the roof thus allowing extra light into the area.
Dormers protrude from the roof and create extra space and more importantly headroom. You may have to install a dormer to meet building regulations for headroom at the top of the staircase. This depends on the location of the stairs, whether it’s in the centre of the loft or slightly to the side where headroom is reduced.
The cost of a loft conversion that requires a dormer is higher than a loft with only roof windows. The difference can be considerable. A loft with two dormers could cost up to twice that of a loft conversion with only roof windows.
Are You on a Tight Budget?
Here are some tips for homeowners that are on a tight budget and want to maximise their profits on a loft they wish to convert:
Understand that bathrooms, shower units and dormers are the most expensive part of the loft conversion. If you can avoid some or all of these you can make a saving.
Can you do some of the work yourself? Such as painting and decorating? Some DIY enthusiasts may even want to install their own bathroom, carpets or flooring. You could get the loft converted and all the electrics and plumbing installed, anything remaining could be done by yourself or someone you know in the trade who could complete the work at a lower price.
Avoid things like increasing the height of the original roof, this will incur significant additional cost and planning permission. Accept that not every loft is suitable for a conversion and in some rare cases the cost can outweigh the return.
Is Converting the Loft Space Cost Effective?
This is the question every homeowner should try to answer; would you get back more than you spent if you were to sell the property?
Here are some simple steps we suggest you follow before instructing a company to convert your loft:
- Look at houses in the neighbouring area, note down any that have had the lofts converted.
- Check past sold prices on Rightmove and compare these to houses on the same street that haven’t had the loft work done.
- By comparing the difference in price you should get a rough idea of how much value a loft conversion will add to your property. Be aware that prices fluctuate over time.
- Also look at larger houses in your area, if you have a 2-bed semi then look at 3-bed semis that have been sold recently.
- Avoid looking at Estate Agent asking prices, instead look at sold prices which are more accurate of the true value.
Also, do bear in mind that bathrooms or en-suite bathrooms/showers are the most expensive part of the conversion. Can you convert the loft into just one or two bedrooms? Do you really need that extra bathroom?
Based on our experience and research, loft conversions are a great way to add space and value to your home. They are usually cheaper than a typical extension and in most cases planning permission is either not required or is fairly straightforward to acquire.
