If your home was built before 1930, there's a very good chance that it has solid walls, not cavity walls. You can still insulate solid walls, but the insulation process is obviously very different - and more expensive. We'll talk you through the benefits of external wall insulation.
Whatever kind of walls you've got, the aim of the game is the same: you want to slow down or restrict the passage of heat through your walls. The savings can really stack up.
Solid wall insulation - the basics
Here's how the solid wall insulation process works. Very basically, the house needs to be checked prior to installation to ensure that any existing render makes a suitable surface for the chosen insulating material. Any pipes must also be removed - but will be replaced at the end of the process.
The chosen insulating material (which may be expanded polystyrene, breathable mineral wool or phenolic resin) will be fixed to the exterior walls of the property with an adhesive mortar and an insulating mesh to hold everything in place. Finally, it will be covered over with cladding or a suitable render for cosmetic effect. This can be smooth, painted, textured or tiled - whatever you feel will suit your house.
Although it's a fringe benefit, the external wall insulation process can dramatically improve the exterior appearance of your home, changing a worn, or dirty looking facade into a smoothly finished, newly painted exterior. It's a bit like a face-lift; you cover over the cracks, smooth out the wrinkles and leave your home looking years younger. So, as well as saving on the cost of the insulation, reducing heat loss and energy bills, external wall insulation can actually add considerable value to your home.

Even more benefits of solid wall insulation
As well as helping you to retain more heat - and reduce your bills, external wall insulation can help to protect against damp and improve your property's resistance to sound. (Useful if you live in a busy neighbourhood.)
The lasting benefits of external wall insulation
Unfortunately this type of insulation is not covered by the government grant scheme at the moment, but keep an eye on our website for any new announcements. New insulation schemes are announced periodically, so keep checking back for the latest news.
It does mean that the cost of solid wall insulation may be too high for many people - in the region of £100 / m2 - but if you can get a suitable grant in the future, it could certainly be well worth while having the work carried out. It really will add considerable value to your home.
Remember, you may be eligible for insulation grants for cavity walls or loft spaces under the government's Energy Company Obligation scheme. Check out our guide and see if you qualify.
