Solid Wall Insulation

If your home was built before 1920, its external walls are probably solid rather than cavity walls. Without a gap they will let more heat escape. Solid walls can be insulated – either from the inside or the outside. This will cost more than insulating a standard cavity wall, but your home will feel warmer and you could save up to £270 per year so apply today.

External Wall Insulation 

CHiL has previously helped hundreds of households to keep their homes warmer by funding External Wall Insulation. CHiL currently has funding available, however levels of funding are subject to survey and in most cases it does not cover the full cost of the work so a significant contribution will be required by the homeowner. If you are interested please register your details.

Also, if you are able to pay but unsure how to proceed, our team has access to 0% finance packages and contractors who are experts in this type of insulation. Get in touch for more information.

Internal Wall Insulation

CHiL currently cannot help fund internal wall insulation, however if you are able to pay, our team are able to advise on reliable contractors who specialise in this work. Get in touch today to find out more.

Can’t find what you’re looking for? We provide funding for a number of heating and energy saving measures specifically for residents across Lancashire including  cavity wall insulation, first time central heating and storage heater replacements.


Internal wall insulation is generally cheaper to install than external wall insulation

Floor Space

Internal wall insulation can slightly reduce the floor area of a room. The thickness of the insulation is around 100mm

Requirements for fitting

Can be disruptive to daily life as work is needed inside, however, this can be done room by room and will require skirting boards, door frames and external fittings to be removed and reattached

Consider wall fittings

Installing internal wall insulation can make it hard to fix heavy items to inside walls – although special fixings are available

Checks beforehand

Note that any existing problems with penetrating or rising damp need to be fixed first
