Is it time?
Is your loft letting the heat out?
Heat rises, so a poor loft is one of the first places a house loses warmth.
Cold upstairs rooms
Bedrooms that never quite warm up, or heating that’s always on.
Thin or old insulation
Insulation that’s been there 10 to 15 years may have settled or gone damp.
Squashed insulation
Boxes on top of insulation press it flat and stop it working.
Nowhere to store things
A loft you can’t walk on safely is wasted space.
Your options
What can we do in your loft?
You can have any of these on their own, and they often work best together.
Insulated boarding and storage
Best for: Storing things without squashing the insulation.
A raised system keeps the boards above the insulation, topped up to the recommended 270mm.

Under-rafter insulation
Best for: Lofts used as a room, or where floor-level insulation won’t work.
Slim boards or multi-foil go under the rafters, keeping the warmth in while keeping your headroom.

“Great experience, came on time, good communication. They worked well and did a good job and cleaned up well before they left. The roof looks great, and we now have a conservatory that we can use all year round. Lovely company to deal with.”

“Following a visit by the Director of Cozy Top Home, to discuss the best options for my conservatory roof. I placed the order, the Surveyor visited and he explained in full detail how the work would be carried out. The two fitters turned up at the time advised, and worked non stop, they did an excellent job, and tidied up after them. I am extremely pleased with the service provided, and would recommend them.”

The work was carried out with 2 brothers who had a good work ethic, got on with the job with precision and cleanliness.

FAQs
Common loft questions
Yes. We fit a raised storage system that holds the boards above the insulation, so the insulation keeps its full depth and keeps working. Boarding straight onto the joists squashes it, which is why many boarded lofts are colder than they should be. You get warmer rooms below and proper storage above.
The Energy Saving Trust recommends 270mm of loft insulation, and the raised storage system we fit is designed to meet that while still giving you a boarded floor. Many older lofts have far less, often just what was put in when the house was built. We measure what you have at the free survey.
Yes. If your old insulation is damp, compressed or past its best, we can take it out and dispose of it before fitting the new. If it’s in good condition, we top it up to the recommended depth instead, which costs less. We tell you which at the survey.
We fit loft insulation, boarding, storage systems and loft ladders, but not full loft conversions. If you’re planning a conversion, call 0115 822 2744 and we’ll tell you what we can help with, such as insulating under the roof, and point you in the right direction for the rest.
Every loft is priced after a free survey, because the size of the loft, the access and whether old insulation needs removing all change the figure. You get a fixed price that includes the insulation, boarding and any extras you choose, such as a ladder or lighting. There’s no obligation to go ahead.
