First thoughts - is Grange over Sands near Sellafield, that would put me off looking if I was moving into the area.
The bungalow itself looks fine from the outside. I'd be a bit concerned about the flat roof on the garage but not enough to put me off viewing, it's to be expected after all.
Picture 2: Put some art on the wall over the fireplace and a vase of flowers on the hearth. Is that a coffee table next to the sofa? Move it to in front of the sofa and put the flowers on there instead. I'd move the 2 seater sofa at the end forwards to make it look like you can sit and chat to the people on the other one, it looks a bit far away. Add some cosy throws and cushions.
Picture 3: Love the view.
Picture 4: Move the clutter off the top of the cupboards and have the photo taken again. Nothing says not enough storage space than stuff on top of the kitchen cupboards thank goodness you can't see mine
Picture 5: Move whatever the piece of furniture is to the right at the front of the photo and get the photo taken again. Add some flowers to the table and move it to a more central position in the room. Add some art work to the left hand wall. I like your map and holiday photos (?) Add tiebacks to the curtains to tidy it up and maybe a nice rug.
Picture 6: Tiebacks for the curtains. Put a lightshade up - just a cheap Wilko one and turn the light on. Put some flowers on the window sill and move the car off the drive when a new photo is taken. Yes, it's a bungalow but have the possibility of a nice view rather than of your car. Put some art above the bed.
Picture 7: Tiebacks! Art above the bed.
Picture 8: Pull the bed away from the wall so the room looks like there is space enough for you to walk down the side of the bed on both sides. Make it look like an adult room rather than a child's room, people might be put off by the thought of a child being able to get out of the door to outside or somebody getting in. If you make it look like a lovely guest room they'll think how nice it is to be able to open the doors and step out into the garden in the morning and enjoy the lovely view.
Picture 9: Brighten up the bathroom with a cheap more colourful shower curtain. Have the lights on when the picture is taken. Add a plant to the windowsill.
