Can my Loft be Converted?
Before you even dream of what your new loft will look like, you need to know if your attic can be converted. The answer is that it depends.

Another option you have is remortgaging your home to pay for a loft conversion, but be careful. If the interest rate on the loan exceeds that of your mortgage, then it’s probably not worth taking out this type of loan.

Having a detailed plan that everyone can work towards will help the job run smoothly and drastically improve the finished result.

Roof Repair Costs
You need to keep in mind that you are already paying for the scaffolding hire, so you might as well make the most of it. The average cost of cleaning a roof is about £450. But, if you already have the scaffolding in place, you should get a reduced rate.
The cost of replacing damaged roof tiles would be about £170 (depending on how many there are). While the scaffolding is erected, it might be a good idea to think about a gutter replacement. You could pay as little as £600 to have all the gutters replaced on your home.
Building Regulation Costs
The cost of submitting building regulation plans for approval can vary between £40-£800. It might be a good idea to ask your chosen contractor if the cost of building regulation approval is included within your quote.
Moving a Water Tank Cost
Unfortunately, if your loft has a water tank, you will have to pay to get it removed. If the water tank is still in use, then it looks like you’re going to need a new boiler installation. If the water tank is no
longer in use, then, unfortunately, you will still have to pay for its removal and disposal. The cost of a water tank removal out of a loft is around £600.
The cost to replace a hot water tank with a Combi boiler is about £3200. Water tank disposal cost a further £100-£200.

If you plan on installing a toilet, shower, or bathroom suite into your new loft, you’re going to need a plumber. Plumbers usually charge around £40 per hour plus the cost of materials.
Underfloor Heating Costs
If you plan to install an ensuite, there may be a good idea to think about installing underfloor heating simultaneously. After all, who wants to step out of the lovely hot shower onto a cold floor?
Fitting underfloor heating at the same time as fitting an ensuite bathroom into a loft would be much easier than trying to fit it at a later date. The cost of fitting underfloor heating in a loft will depend on the size of the room. A guide price would be anywhere between £350-£850.
Truss Style Roof Costs
The type of roof you have will depend on the amount of work required (and the cost). If your roof has trusses, it is possible to do a conversion, but it will cost quite a lot more money. The reason for the added expense is because the roof has to be externally supported while the loft conversion work is underway.
If roof joists are required, you will have no option but to hire the services of a structural engineer. The cost of hiring a structural engineer to fit roof joists varies between £500 and £1000.
Loft Conversion Stair Costs
Loft conversion stair costs are one of the last things to consider before beginning your project. It can be tempting, and sometimes necessary, to save money on parts that may not seem as important at first glance when in reality, a lot of risks are involved with cutting corners during this phase. The cost for loft stairs usually ranges from £1200-£2500 per set.
It’s worth noting that these prices do vary depending on who installs them. Make sure you know what each company charges and what is included before signing any contracts!

Do You Need Planning Permission for a Loft Conversion?
For the vast majority of cases, planning permission for a loft conversion is not required. Most loft conversions are safe to go ahead because of something called permitted development. Ask your builder or architect whether you need planning permission or are covered by permitted development. If you adhere to the following guidelines, it should be safe to go ahead with your conversion.
- No raised platforms, verandas or balconies are added.
- The roof height is not increased.
- The materials used for the conversion are similar to the ones used on the existing property.
- The 40 m³ limit for terraced houses and the 50m³ limit for semi-detached houses is not exceeded by the extensions.
- Clear glass is not used inside facing windows.
- The conversion doesn’t hang over the original walls.
- The roof extension falls at least 20 cm short of the original eaves (apart from head to gable conversions).
- The loft conversion will not exceed the existing roof slope at the front of the house.
Building Regulations For Loft Conversions
Whether you applied for planning permission or not, a new loft conversion will still have to meet building regulations. If you ever decide to sell the property, a new loft conversion would have to meet the required building regulations. Building regulations aim to make sure that the conversion is structurally sound and the rooms are safe.
Complying with building regulations might mean having to alter some of your original plans as well as your choice of building materials. The layout of a loft conversion may have to be altered to follow building regulations. An example would be if you have a room at the top of the staircase, you will need a door. Fire safety measures for a loft must be a top priority for the safety of you and your family.
Check with your builder or architect that all of the work will meet building regulation standards. During the work, your contractor should arrange inspections to make sure everything is done right.
For your peace of mind, ask your builder if there will be building inspections during the course of the work. Ultimately, it is your responsibility to make sure that planning permission has been granted and all the work meets building regulations.

Where do Loft Conversion Stairs Go?
In the early stages of planning a loft conversion, you may be wondering where do loft conversion stairs go? This question gets asked a lot. Many people tend to focus on the conversion itself and give little thought to how they plan to access their new room.
It is possible to extend from the existing staircase into the new room, creating a more seamless design. However, if it isn’t possible to extend from the existing staircase, then the only other option is to install a new staircase in a room with more space.

What are the Benefits of a Loft Conversion?
There are many unforeseen benefits of having a loft conversion. You may have already thought about some of the obvious benefits, but take a look at some of the less obvious ones below.
Increases the Value of Your Home
Although converting your attic into another room can be quite expensive, it is not dead money. Consider it an investment. When the time comes to sell your home, the resale value will be much higher. One of the easy ways to increase the value of your home is to add a loft extension.
Avoid the Cost of Moving
If your family has outgrown your home, you only have two options. Move up or move out. Converting a loft into another room will save you the hassle and expense of moving into another home.
More Natural Light
If you choose to have a stairway built for a loft conversion, you might want to think about installing windows alongside the stairway. The extra windows will allow a flood of natural light into your home. It’s been proven that natural light is beneficial to your health in several ways.
More Energy Efficient
Your home will become more energy efficient after a loft extension. The added insulation will help your home to retain heat. Expect your energy bill to be reduced during the winter.
Get Extra Space without Sacrificing Your Garden.
If you have a young family, it won’t be long before your home doesn’t feel big enough. At some point, you will have to choose whether to increase the size of your home or sell up and move.
If you want to stay where you are, you can either convert your attic into another room or build an extension. Unfortunately, an extension will take up valuable real estate in your garden, whereas converting a loft won’t.
Would you really want to sacrifice a beautiful garden?
That’s a tough call and only one you can make.
Will a Loft Conversion Increase the Value of my House?
One of the best ways to increase the value of a house is by adding a loft conversion. The resale value of your home could increase by as much as 22% by converting a loft into another room.
If the only reason you are thinking about having a loft conversion is to increase the value of your home, stop right there! You must carry out some research before spending your money. You need to be aware of the house price ceiling that affects most areas.
For example, the maximum amount of money houses sell for in your area is around £350,000. If your home is currently worth £340,000 would you want to spend £30,000 on a loft conversion if you have no chance of recuperating the money if you are to sell?
It makes little sense to spend large sums of money on your house if it does not increase the resale value in your area. Make sure you carry out some research before making a decision.
