Sometimes you just need some peace of mind when you come to place an order for your blinds. With DotcomBlind’s Right-Size Guarantee you can have just that. With our Right-Size Guarantee we will replace a blind with the correct size if you get the measurements wrong when you order.
Why do I need this Insurance?
We can’t accept returns or provide refunds for blinds that are mis-measured because all of our blinds are made to measure and so the onus is on the customer to get the measurements right for their blinds. Sometimes you might just be having an off-day, get your centimetres and inches mixed up and end up with a blind that is nigh-on useless. With our Right-Size Guarantee we will take that blind back, remake it to the correct size for you and send it back, saving you from having to buy a totally new blind!
How does it work?
✔ Purchase Right-Size Guarantee when you place your order
✔ If one of your blinds has been measured incorrectly, get in touch with us within 14 days and we’ll tell you how to return the blind to us.
✔ Once your blind is with us, we’ll remake it or adjust the blind to your correct measurements and send it back.
✔ Please read our terms and conditions for full details as you will incur additional costs returning the blind to us.

The possibilities with an electric blind are virtually endless. The motor is battery operated, meaning it can be installed anywhere without the need to hardwire it.
The 7.4v DC motor and battery is tucked inside the barrel of the blind, meaning it is a clean and simple installation with no excess parts to consider. Our remote controls are sold separately. It is possible to use a single remote to control up to 6 blinds simultaneously or individually.
The remote will connect to the motor inside the blind once you’ve followed the programming instructions. After which, the motor will know where the top of the blind is and where the bottom is, allowing you to simply hit the button and it will work without over-spooling itself.
Our blinds also have the ability to set stop points down the window which means if you press the button once it will go to the first stop point, which may be a quarter of the way down the window, for example. Press the button again and it can go to the next stop point, which could be halfway down the window. This level of programming is useful for limiting direct sunlight throughout the day but still allowing some daylight in.
Due to the electric components in our blinds it is not recommended the blind comes into contact with any water or moisture. Therefore we don't recommend our blinds are installed in bathrooms or areas of high humidity.
How to Measure
Now, you can’t mess this one up. It’s what we call ‘easy’ here at DotcomBlinds. But just in case you need some help, follow this quick guide.
First thing's first, identify whether your blind is going inside or outside of a recess.
Inside the recess
A recess fit blind means you supply us with the width and drop of your recess – from top to bottom and wall to wall. We make deductions to account for the brackets to ensure your blind fits within the recess perfectly.
To measure a roller blind to fit inside the recess of your standard window, simply measure the full width and the height of the recess. Then input those measurements into the product page with your order selecting the ‘recess’ option. We’ll do the rest, leaving you the well-deserved excuse to put your feet up, you worked hard for it after all!
Don’t be tempted to deduct any measurements, we do this for you. Make sure you use a metal tape measure; a cloth one can stretch and give you more millimetres per centimetre than a pound-shop ruler. Also, take your measurements in three places and give us the smallest (if there is a smallest). You will find that some recesses shift and settle over time.
Outside the recess
A blind going outside of a recess is usually called an exact fit blind. An exact fit blind means we won’t make any deductions to the width or drop measurements. Exact fit is the bracket to bracket measurement and is commonly found installed outside of a recess. The size you give us is the size your blind is made to.
If you want your blind to hang outside the recess, measure the height and width but be sure to add some overlap to reduce light leakage. This overlap should be about 70mm at the top and bottom and 50mm each side, ensuring you suffer no dazzling strips of sunlight once your blind is happily installed. Please select the ‘exact’ size option when ordering.
How to Install Battery Blinds
Installing a battery-operated electric roller blind is as easy as fitting any other roller blind in our range – drill two holes into the top or side of the recess if recess-fixing the blind, or in front of the recess or window if you’re face-fixing the blind. Insert the wall plugs and screw the bracket down and put the blind into the brackets. Due to the fact that the battery and motor and enclosed within the barrel of the blind, there is no need to make any further deductions or changes to your measurements to accommodate for it.
Programming your blind is simple. Once your blind has been installed, you will need to get the remote control and the motor to talk to each other, let the motor know where the top and bottom of the blind is, and set stop positions in between (optional). Your battery in the blind will come with some charge in it from the factory, but it typically takes four hours to fully charge the battery so put your feet up for a while to let it charge up some more.Step 1
First thing we need to do is pair the controller to the motor, think of it like connecting a bluetooth device to your phone (only it's not bluetooth and it's easier!)
Using a small, thin Phillips screwdriver or pin, press the “Prog” button on the motor and it will beep. This is located at the end of the blind near the wire, on the bottom, within a tiny hole (to avoid it being mistakenly pressed whilst in operation). Press and hold the “Prog” button for one second and the blind will beep, this has taken the blind out of sleep mode, press the "Prog" button again for one second and the blind will shunt once (a sort of judder!), the shunt tells you that the motor is now in program mode.
On the remote control press the ‘Down’ button, and the motor will shunt once again. You have successfully paired the remote to your blind.Step 2
Now that you have a paired controller and you’ve woken up the motor, it’s time to take that bad boy out for its first test run! Test that the blind is rolling in the correct direction by pressing the down button. Did the blind start to unroll? If it did then excellent your blind knows up from down! Skip the rest of this step and go straight to Step 3. If the blind starts to go up when you press the down button on the remote then it's inverted and we just need to switch it round (which is a piece of cake)!
Press and hold the ‘Stop’ button in the centre of the remote for five seconds, and the motor will shunt once. Now, press the ‘Down’ button and the motor will shunt again. There you go – ‘Up’ is up and ‘Down’ is… well, you get the gist.Step 3
This is the step where you tell the blind where the top and bottom of the window is, and therefore where it needs to stop every time you want it to open or close. This is called a ‘Stop Position’.
Press and hold the ‘Prog’ button on the reverse of the remote for one second. The motor will shunt once. The first ‘Stop Position’ you are going to set is the top, so press the ‘Up’ and ‘Down’ button on the remote until the blind is in the spot where you would like it to stop when it is open. Once you’re happy with where it is, press and hold ‘Prog’ on the reverse of the remote for one second to save the ‘Top Stop Position’. If there is no action from you within 30 seconds the motor will exit the ‘Stop Position’ preparation mode automatically.Step 4
Now we’re cooking with gas! Look at you go, setting up your ‘Stop Positions’. Now, you need to repeat Step 3 to tell the blind where to stop at the bottom of the window, and then set them for any ‘Stop Positions’ you’d like in between. Maybe a half-open-half-closed setting for those moments of indecisiveness, or perhaps a low ‘Stop Position’ to block the sun from blinding you at five in the afternoon. You have up to four more Stop Positions between the top and bottom to enjoy, so what are you waiting for?! Setting additional intermediate stops isn't a must, it's completely a "personal thing", but you must have a top and bottom stop set.Step 5
We know what it can be like – you live with your ‘Stop Positions’ for a week and decide that actually, you didn’t quite get it to stop in the right place. No worries – here’s the quick fix for fine tuning your ‘Stop Position.’
Let the motor run to the ‘Stop Position’ that you want to fine tune. Press and hold the ‘Prog’ button on the reverse of the remote for one second, until the motor shunts. Within seven seconds the motor will shunt again, indicating that the ‘Stop Position’ has been cleared and you’re free to set your new ‘Stop Position.’ This is only applicable to the intermediate stops, if you ever want to reset the top and bottom stops you'll need to perform a factory reset as shown in Step 5.Step 6
This step is pretty final, so unless you want to reset the motor to the factory settings, don’t do this!
Press and hold the ‘Prog’ button on the motor for seven seconds and the motor will beep once and shunt. When the motor beeps again after seven seconds, the memory has been cleared.
Alternatively, you can reset the motor this way: Press and hold the ‘Stop’ button on the remote for five seconds, until the motor shunts once. Press and hold the ‘Prog’ button on the reverse of the remote for seven seconds, within 10 seconds of pressing the ‘Stop’ button. The motor will shunt once. After seven seconds, the motor will shunt twice, indicating that the memory has been cleared.
And there you have it: you’ve programmed your DotcomBlinds blind and you’re all set to enjoy your blind in electrical bliss.
‘Why do I have to do this?’
‘Can't you have done it for me when you made my blind?’
Good point and the short answer is yes! However, knowing where you want to set your stops is a completely personal thing and if we did it for you then it could cause you frustration when installing and operating the blind and you'd end up performing a factory reset and doing it yourself! Instead we test every motor and controller and then in the final stage of testing, we reset them. This means we have peace of mind knowing that all's good and you'll be able to set it up the way you want.

Electric Roller Blind Technical Specifications
Our roller blinds are made to the highest standards. They are made using an aluminium barrel and the fabric is locked into the barrel, holding it securely in place. Depending on the size of the blind and the weight of the fabric, our barrels can have a diameter of 32mm, 40mm or 45mm, which we select automatically when processing your order at no additional cost.
The bottom bar is covered with the fabric of the blind to muffle any sound it may make against objects on the window.
The brackets are white metal and can be used to face fix, top fix or side fixed and they come with white plastic brackets covers too. As standard the fabric of our roller blinds is back rolled, meaning it rolls off the back of the barrel, closest to the window.
There is a chance on a wider width roller blind that it may have a join in the fabric running horizontally near the top of the blind. For wide blackout blinds particularly, this join is welded to ensure no light can get through.Motor Technical Specifications
This 7.4v DC battery powered tubular motor comes with an inbuilt radio receiver. The tubular motor enables a 230v AC feed to power the motor which operates incredibly quietly. It has a noise level of 40dB and has a nominal speed of 30rpm. The remote control needs to be purchased separately and is not supplied with the blinds.
To protect the motor from overheating and to prolong the life of the product, the motor will cut out after more than four minutes of constant use to allow it to cool down.
Overall the motor weighs 0.6kg and is enclosed within the barrel of the blind, meaning the blind can be cleanly installed with no added requirements needed to be accounted for.
The optional extra solar panel charger is made from amorphous silicon panels with a scratch resistant high strength aluminium frame. It measures 375mm x 50mm x 3.2mm and is for indoor use only. This can be purchased separately in the Accessories section.
The solar panel can be mounted to brackets positioned 342mm apart and has a cable that is 2.3m which connects to the battery. In full sunlight, the battery will be full charged in 2 days, but a mains charger is supplied with all solar panels in case the battery needs faster charging or the area is particularly deprived of sunlight.

A discreet wall-mounted remote control switch is a must. This switch is both functional and discreet and incorporates light illumination for ease of use.
Dual Channel Wall Mounted Remote Control Switch
A discreet Dual Channel wall-mounted remote control switch is a must, controlling two separate blinds. This switch is both functional and discreet and incorporates light illumination for ease of use.
Alongside the above extras, you are also able to purchase additional mains chargers and solar chargers should you need.
You can purchase our electric blinds accessories and extras here.
To keep your blind running smoothly, you'll need to top it up with power from time to time, no different to your mobile phone, but thankfully nowhere near as often! In fact, on a full charge you can expect your blind to work seamlessly for up to 6 months on standard usage.
Mains Charger Only Option
Each DotcomBlinds Electric Blind will come with a mains charger. Simply plug into a mains power socket and connect it to the blind. The blind can remain in place while being charged so there’s no need to remove it.
A full charge of the battery will take around 4 hours and based on standard usage of twice a day you should expect up to 6 months of usage.
Solar Panel Charger + Mains Charger Option
If you don’t want to worry about needing to charge your battery, you could opt for the addition of a Solar Panel Charger. This plugs into the charging port of your blind and can either be mounted to the recess with the solar panel facing the window. This can be purchased separately in the Accessories section.
This will then provide a “trickle charge”, permanently keeping your battery topped up and ready to go!
If you aren’t getting enough power, either through insufficient sunlight coming through the window or heavy usage, you can always top the battery up with the mains charger supplied, although for most situations you shouldn’t need to do this.
Little Note:Estimated battery usage will depend on the number of times the blind is used within 1 day as well as other factors such a size and weight of the fabric, but within our tests, up to 6 months is a good indication.
Cable length for both chargers is approx. 2m in length
