Old Terraced House Wall Insulation Advice

bloke91

Hi,

I am thinking of renovating a 1930's ish four bedroom terrace property as a potential investment opportunity.

Read about some new regulations coming in where properties cannot be rented unless have an EPC rating of C or higher, so suspect will need to insulate the walls in order to achieve a rating of C or higher.

I think the property may have solid wall rather than cavity wall.  Have a few questions looking for some advice on please:

1. If I hired someone to install internal solid wall insulation, presume I would only need to do this on the external walls and not the side walls (due to being a terraced) or other internal walls?

 

2. I am aware will lose about 4 inches of space with internal solid wall insulation, but there are any other disadvantages? 

 

3. Would it be hard to hang anything heavy such as shelves or fit a tv to the walls that are internally insulated afterwards?

 

4. Can you share any indicative average costs for this?

Thanks in advance or any comments, thoughts and recommendations.

Only the external walls need doing. Where the TV etc is going stick some extra noggins in.

If you are insulating in order to improve the EPC rating ready for rental, don't forget the loft and any flat roof. It would also be worth insulating under the ground floor if it is suspended timber - Do this in conjunction with the walls, and you can avoid any cold spots & kill the source of most draughts in one hit. Just be careful not to compromise any underfloor ventilation.
