This is an formal firm to deal with. After the free survey, where the surveyor modified my error on the type of loft support I wanted. No deposit was required. During the time between survey the office team reserved me updated on the process. About a week already they arranged for a primary start and finish to avoid the worst of the heat that was prediction. The loft space took 69sq meters of insulation and 220sq foot of new boarding. Their work is guaranteed for 10 years! I would strongly recommend them.

FAQs
Generally a basement conversion project takes from a week to over a month. The time period of the project completion varies on the complexity, size as well as the location of your project. It also depends on the expertise and the availability of the required professional such as architect or the structural engineer.
If you are not going to make any significant change in your basement, then there will be no need to get the planning permission. In case you are going to do any structural changes specifically if you have a shared wall, then you might need the planning permission as well as the party wall notice.
If you convert your basement into a functional living space, it will benefit you in many ways. It also increases the resale value of your property.
You can absolutely add the bathroom or kitchen while doing the basement conversion. But first, make sure that your basement has the proper plumbing, ventilation and damp proofing system and comply with the building regulations.
In the UK building regulation, there is no specific basement height mentioned, but 24 meters can be considered as the practical minimum height for your basements.

It is generally best to insulate your basement walls rather than the ceilings. The reason behind it is that most of the heat loss occurs through the walls that are directly exposed to the cold ground outside.
