External Wall Insulation
A solid wall consists of just one wall construct, usually using two bricks that interlock at around a thickness of 9 inches thick, allowing heat and moisture to travel through the brickwork.
Unlike cavity walls that have the additional layer of single skin brickwork to prevent heat loss and protect the inner walls from driven winds and the hard-hitting rain, this makes the solid wall construct more vulnerable to both leaking heat and a cause for water penetration, which usually causes ongoing damp/mould issues.
The external wall insulation method of installation usually takes five days to complete. It involves using EWI insulated boards (70mm – 100mm) to the external walls using the dot and dab method and then the application of mesh and a special type of rendering to apply a finish, which can range from smooth, textured, painted or using pebble-dash.
Benefits:
The main benefit of external wall insulation is the amount of heat retention of approximately 45%. This improves indoor thermal comfort, reduces heating costs and limits coâ‚‚ pollution and noise from outside traffic and congestion.
On average, you will save around £350 - £450 each year from external wall insulation, which does not consider the additional savings of installing loft insulation or double glazing.
-
Will renew the appearance of outer walls.
-
Will improve weatherproofing and sound resistance.
-
Fills cracks and gaps in the brickwork, which will reduce draughts.
-
Increases the lifespan of your walls by protecting the brickwork.
​
You may need planning permission (check with your local council). Will require good access to the outer walls, Possible scaffolding (where needed)

Benefits and Savings Overview
Grants for insulating rooms in roofs, such as loft insulation grants, are designed to enhance energy-saving efforts in the residences of low-income individuals and families. Installing loft insulation can lead to yearly savings of £120 to £280 on energy expenses.
Eligible recipients, especially those receiving income-based Jobseekers Allowance and residing in their own homes, may have the entire cost of installation for loft insulation covered. In addition to cost savings, both loft and wall insulation substantially reduce the carbon footprint of your home, making the decision to insulate your loft a financially and environmentally sound choice.
Why Should You Consider Applying?
Obtaining the grant offers more than just lowering energy expenses; it’s about promoting a cozy, energy-efficient lifestyle. The benefits extend to flat roof insulation, which positively influences your energy performance, as indicated by your Energy Performance Certificate (EPC rating significance).
With assistance from UK Energy Support, you can facilitate a seamless shift toward increased yearly savings. This encompasses exploring different insulation types, like cavity wall insulation grants or installing internal solid wall insulation, enhancing your loft space and diminishing CO2 emissions further.

Room in Roof Insulation
Have you a loft conversion that was not insulated or is over 20 years of age and is constantly either too cold or warm?
Room in roof insulation is where we remove the existing plasterboard, expose the original framework, use vapour layer controls and insulate using PIR EPS Foam Rigid Foil Back Boards, including reflective foil sheets and foil back plasterboards to increase the energy efficiency and decrease the U-Value and increasing the R-Value. Using this method will retain heat by 30%, act as a barrier for the summer period, and save you on average £300 – £400 per year on your energy bills.
