A loft and cavity insulation technician works as part of a team insulating the walls of new and existing buildings, and laying loft insulation to meet industry safety standards and customer requirements.

The Work

You could be:

• doing a survey to decide on the type of insulation to use and how much is needed according to building regulations
• checking that the cavity between the two walls is suitable for filling
• marking out existing ventilation points, wiring and pipework
• loading insulating material – wool, foam, granules, fibreglass or bead – into the van and driving to the site
• using a hand-held drill, pneumatic or electric, to bore a set pattern of holes in the wall, drilling from the outside in old buildings and from the inside in new buildings
• operating a machine to pump or blow the insulating material into the cavity between the walls
• checking that you have filled the whole cavity
• repointing the drill holes to match the existing external mortar and cleaning up
• fitting loft insulation and lagging pipes and tanks.

Pay

The figures below are only a guide. Actual pay rates may vary, depending on:

• where you work
• the size of the company or organisation you work for
• the demand for the job.

Starting salaries are around £7.50 to £8.00 an hour rising to around £10.00 an hour after training. With experience this can rise to around £14.00 an hour. You can also earn commission and bonuses on top of this. Some companies also provide a van.

Self-employed cavity wall insulators are paid by the square metre and tender for the contracts in competition with rival insulating firms.
