Loft Conversions: All You Need to Know
May 14, 2019

When your family grows, you’ll either be looking to move into a bigger house, extend your house or convert your loft into an extra room. Even if it’s just for a guest bedroom or an extra entertainment area, a loft conversion is one of the simplest ways to extend your property while simultaneously adding value.

So, how much do loft conversions in London cost?

Loft conversion costs

Similarly, to basement conversions or new bathrooms, loft conversion costs are dependent on the size and the type of conversion you’re wanting to do. You will also need to factor in the costs of installing a staircase leading up to your loft if you do not already have one.

As an estimate though, loft conversions in London will average anywhere between £30,000 and £50,000. Again, these amounts will vary. They also depend on the renovation company you choose to hire.

Let’s break it down a little further:

room in the roof loft conversion

·         A room in the roof conversion

This is the simplest kind of loft conversion, which usually involves the following:

  • electrics
  • lighting and heating
  • fire safety measures
  • a floor reinforcement
  • a skylight
  • insulation
  • a staircase for access

This type of conversion will cost you anything between £1,150-£1,350 per square metre. This usually works out to be around £15,000.

·         A dormer loft conversion

Dormer loft conversions are quite popular because dormer windows are added to the space in order to increase the volume of the roof space while allowing full head height. 

This type of extension is typically added to the rear of your home, but, if your land and local authority allow, you could be able to add one to the side or front of your home.

This will usually include all of the aspects a room in the roof loft conversion will include, but you can expect to pay around £20,000 for the basic conversion because of the dormer window. So, anticipate anywhere between £1,250-£1,450 per square metre.

·         A mansard loft conversion

One of the priciest of all loft conversion in London, a mansard extension will cost you anywhere between £35,000 – £45,000. This kind of conversion has a flat roof, with the back wall sloping inwards.

Windows are usually housed within small dormers. So, bank on around £1,500-£2,500 per square metre.

·         A hip-to-gable conversion 

Another option for loft conversions in London specifically is a hip-to-gable loft conversion. You will need to convert the sloped side of your roof into a flat edge which will provide extra space inside your loft.

For this, you can expect to pay anything between £25,000 – £30,000. So, on average around £1,500-£2,500 per square metre.

Ready-made loft conversions in London

Your most expensive option, but with reduced labour costs is a read-made loft. This is a huge logistical undertaking as the loft is made off-site and then craned into position. For this, you can expect to pay about £55,000. 

With your loft conversions, your best bet is to consult a professional conversion company, as they will advise you on the most logical and cost-effective option for your space and budget. For experts on loft conversions in London, contact us at renov8experts today.
