Hiring a tradesman to install solid wall insulation
Insulation is a key part of energy efficiency. In the average home around a third of heat loss occurs through the walls, and this amount is even higher for solid walls. With proper insulation you could save hundreds on your yearly heating bills, so much so that the installation could pay for itself within a few years!

What do I need to know about solid wall insulation?
While modern homes tend to be built with cavity walls, many homes built before the 1920s have solid walls. Uninsulated solid walls lose nearly twice as much heat as cavity walls. With no cavity, a solid wall is insulated on either the internal or external side. While they are both viable options, they each have certain advantages and disadvantages. Though insulating a solid wall is more expensive than doing so for a cavity wall, the savings will be bigger!
Installing insulation on an internal wall is the cheaper option; you could expect to spend between £3000 and £14,000. Rigid insulation boards are fitted to the inside of a room’s walls, or else a stud wall is built to create a cavity where insulation can be placed. This work on the internal walls will reduce the floor space of a room, as the insulation will be around 100 mm thick. You will also need to relocate any plug sockets and radiators, and once the work is done you will need to redecorate each room. Any skirting boards, door frames or external fittings will have to be removed and reattached, and the newer walls will not be as able to support any heavy items.
If you choose external solid wall insulation, the price will set you back between £5,000 and £18,000, but this option offers a number of advantages. Firstly, installing external insulation is non-disruptive, and you will not reduce the internal area of your rooms. It also renews the appearance of the outside of your home; many homeowners choose finishes ranging from textured, painted, smooth, panelled, pebble-dashed or tiles. Choosing this option will also increase the weatherproofing and sound-resistant qualities of your walls, and will fill in any gaps in your brickwork to reduce drafts. Finally, outside insulation will reduce the condensation on your internal walls and help prevent damp. The main drawback is expense, but you can save money by having external insulation installed during another home improvement project. For example, converting a loft requires scaffolding, which you can also let your insulation installers make use of.
With external solid wall insulation it is important to ask your tradesman about what type of insulation they will use. Breathable (also called vapour permeable) solid wall insulation will allow air to flow through the house, not cooling it but preventing the building up of moisture, which in turn prevents damp. If your installer recommends an alternative, ask them about how else you can prevent this. Another important fact to consider is that external insulation will need to comply with building regulations for thermal performance. Make sure to get in contact with your local authority if your property is listed, or if you will be making any extreme alterations to its external appearance, as the job may require planning permission.
It is important to always check the background of your potential hires. An insulation specialist will usually have learned their trade either on the job or through an apprenticeship scheme. Any well established professional should be able to offer proof of their qualifications, as well as positive reviews from previous customers. A good sign of a candidate’s quality is if they belong to a national tradesmans’ association, such as the Thermal Insulation Contractors Association (TICA). Any tradesmen belonging to a group like this will have to continually meet their high standards for quality and professionalism.
You will also need to consider safety; certain types of insulation can cause irritation if they come into contact with the skin, eyes or lungs, and so your final hire will need to use appropriate Personal Protective Equipment (PPE). They will need easy access to your walls, so make sure the space they need is clear beforehand. Finally, your hire will need to have active Public Liability Insurance, as well as a guarantee for their work.
