Insulation Survey - Free Home Insulation

Before you can have insulation installed, one of our approved Installers will need to carry out a Home Insulation survey of your property.

The survey will typically last no more than an hour, depending whether the surveyor is checking both the loft/roof and the walls.

Why do I need a Survey?

There are certain criteria that your home must meet to be able to claim grant for Home Insulation. The surveyor will assess whether your home meets this criteria and will verify your grant entitlement.

The surveyor will assess whether your property is physically suitable for Cavity Wall, External Wall or Loft Insulation. This will include checking for damp problems, which need to be dealt with before Insulation is installed, and looking for factors such as adequate ventilation and loft access.

Why do I need a Survey?

The Loft Insulation Survey

There are a number of factors to check, including:

  • Depth of Insulation already installed (must be under 4 inches/100 mm).
  • Size of the area which needs to be insulated.
  • Whether ventilation is adequate.
  • Whether there is any damp present.
  • Size of the hatch (must be 16 inches/40 cm square).
  • Headroom is sufficient. Should be at least 4 foot/1.2 m.
  • Position of the hatch in relation to tanks and pipes.
  • Amount of pipework to be insulated.
  • Number of cold water tanks to be insulated.

The Cavity Wall Insulation Survey

Not every home is suitable so the surveyor will carry out detailed checks, including:

  • Width of the cavity in your walls.
  • Area of Insulation required.
  • Type of structure.
  • Condition of the structure.
  • Services (wiring etc.) through the cavity.
  • Whether the cavity is free of debris.
  • Whether any damp is present.
  • If the damp course is defective.
  • Whether the cavity tops are sealed.
  • Whether ventilation is adequate.
  • Access to the exterior of the walls.

The Internal or External Wall Insulation Survey

The External Wall survey will include:

  • Area of Insulation required.
  • Type of structure.
  • Condition of the structure.
  • Services (flues etc.) through the walls.
  • Fittings & fixtures to be removed & replaced.
  • Whether any damp is present.
  • If the damp course is defective.
  • Whether ventilation is adequate.
  • Access to the walls.

How long will it take to be contacted?

Waiting times vary, depending on the time of year that you apply but are typically shorter in the Spring/Summer months when demand is lower.

In the run up to the colder Winter months, it can take longer for one of our approved Installers to contact you. This is due to increased demand, as households look to take advantage of Home Insulation to make their homes warmer and cut energy bills.
