The Average Cost of a Loft Conversion

loft conversion cost infographicEach loft conversion is unique, which is why they have to be priced individually – your cost depends on a range of factors including the type of loft conversion, number of windows, your loft conversion use, and the materials used to build your existing home.

However, we can offer rough guidelines so that you know what to expect from your personalised loft conversion quote. To get an exact price for your conversion, get in touch to arrange a no-obligation quote.

Work & Materials Involved in a Loft Conversion

Our useful infographic above breaks down the cost of an average loft conversion to individual items. This includes:

  • £1,200 on building materials
  • £2,500 on triple or eco glazing (which keeps your heating bills down in the long term)
  • £1,000 on standard glazing
  • £2,000 on insulation
  • £2,000 on plumbing (if you are adding a bathroom)
  • £1,800 on stairs
  • £1,500 on roofing materials
  • £800 on a bathroom
  • £535 to decorate the room
  • £1,200 on labour

Giving you an average price of £13,000-£14,000 for a standard loft conversion with a bathroom. Without a bathroom, and without eco-glazing this can be cheaper, and if you would like a larger loft conversion, a Mansard conversion, or any higher-end variations the cost is likely to increase.

For that cost, you gain:

  • Up to 1/5 onto the value of your home
  • Up to 30% more living space

There was a 15% increase in the number of loft conversions built in 2013 and we expect to see even more in 2014.

Eco-Friendly Additions

There are plenty of eco-friendly additions that you can make to your loft conversion to minimise your impact on the environment. This includes triple-glazing, solar panels, and using green building materials.

Around 3000 solar panels are installed every single week in the UK, offering savings of £750 per year on electricity. If you’d like to build an eco-friendly conversion, let us know and we’ll explain your options and provide full pricing.
