I think Chris Dinham and Ryan Monaghan have answered your query perfectly. I would also check to see if you are eligible for any grants towards the cost.

Another option would be to use a product which is available from B & Q as well as other DIY places:
Wallrock Natural Thermal Liner by Erfurt
The Wallrock Thermal Liner is also an excellent cover for cracked plaster work and unfashionable textures. Allows walls to breathe and resists mould and damp formation and produces a stable surface for wallpaper.
I've used it on a few jobs and been very impressed with it. Its a cheaper option than some of the other ideas and less messy too!
The best way would be to put a membrane on the inside wall , then put some stud work up with room for insulation, then plasterboard and skim . This will make your rooms warmer . For the condensation put a air vent in the correct position for air flow.
Best to get an on site survey/quotation done, this is a free service to you and you will get 3 quotes. Simply post your job onto rated people's site.
You are not obliged to go with any of the quotes- but ever job that's posted is paid for by the relevant tradesmen.if they contact you that means they are interested in your job. If one of them are awarded the job then great news for you both.
Hi Carolyn, without seeing the rooms i would suggest lining the walls with a polystyrene which comes on a roll like wallpaper, it is about 5mm thick and is hung like wallpaper. i would then hang lining paper over the top so you can decorate to your taste.

you can get a firm in to basically shoot insulation into your cavities via holes drilled in the exterior brick work.Some people have been able to get this done for free.Worth looking into.
If they are single skin walls then you can 50 mm batten and with 50mm insulation in between and plasterboard over aqnd skim.
first of all to stop the damp paint bitumin on the walls and let it dry the next day put 50 mm battens on the wall with plastic dpc between battens and the wall in between put celotex these are normally .450mm wide the distance of each batten on the wall then to the battens fix foil back plaster board and then plaster
if its just the inside you want to tackle you could have timber batten fitted to the walls at 400c then use a vapour barrier stapled to them horizontally. Then screw thermal backed plasterboard to the battens. They come in various thicknesses from 1round 30mm upwards. obviously the thicker you can afford to use and without losing space in the room the better.
Its not a huge job to do although sockets and radiators may have to be altered too!
If it is a double brick wall you could have it filled with cavity insulation.
If it is single brick you need to make sure the loft is well insulated or an alternative would
be to insulate the walls themselves. There are products on the market but browsing the web
might be a good idea to see exactly what is out there.

Hi Carolyn you can either batten walls with 2 by 1 battens & membrane and fix 25 mm insulation board & plaster
Or dot & dab walls with insulation board & plaster
You will loose about 40 mm in size of room which is roughly 1.5 inches
But this way will leave you a small cavity
Before your walls can be insulated get a second opinion to wether its condensation or damp?? Any problems with penetrating or rising damp must be resolved first. Insulation should not be used to cover, hide or isolate damp as this could lead to serious problems in the future.
You can insulate it internally using an Internal Wall Insulation Accredited Installer. You may also be able to get partial funding to help towards the cost, as yours may be classed as a hard to test property. As far as condensation goes. you may want to consider looking at using products by a company called Envirovent. I had a similar problem with a rental property and we insulated the property and used an Envirovent product. Problem sorted.
Hope this helps
