3. How much will a loft conversion cost?

There is no size-fits-all approach for all types of loft conversions. Many factors come into play while deciding the cost of loft conversion.

Let’s break the loft conversion costs further and understand what will be the cost of loft conversion depending on its type.

Rooflight Loft Conversion or Velux Loft Conversion

Rooflight Loft Conversion or Velux Loft Conversion

This is one of the best, simplest and most affordable amongst all loft conversions. Rooflight loft conversion requires minimum alteration to your roof.

Here special windows known as roof lights or skylights are installed in the roof to illuminate the attic space with natural sunlight and to aid better ventilation.

Generally, the process followed is:

  1. The existing floor is strengthened.
  1. Flooring and insulation are completed.
  1. Installation and plasterboarding of roof lights are done.
  1. The roof is then finished while keeping the original look intact.
  1. Staircases are added to make the new space accessible.

Cost of Rooflight Loft Conversion

For Rooflight loft conversion, also known as Velux Loft Conversion the average cost can be anywhere between £15,000 and £25,000. This comes out to be generally around £1,150 – £1,350 per square metre.

Dormer Loft Conversion 

Dormer Loft Conversion

If you are looking to add a good headspace and floor space to your abode, then go for dormer loft conversion. Here a dormer is added to the pitched roof along with rooflights on the opposite side of the converted roof.

A box-shaped structure known as a dormer is added to one of the sloping roofs. This gives a flat roof space in your loft allows you to install full-height furniture and convert the space into your favourite living area.

Most of the dormer loft conversions come under the Permitted Development rights with the exception to a few areas such as conservation and similar zones.

Cost of Dormer Loft Conversion

The cost of dormer loft conversion is a bit higher than rooflight loft conversion as it involves rebuilding the entire roof along with other works.

The average cost of loft conversion dormer starts from £20,000 for a basic one. But, normally the cost ranges between £25,000 – £50,000.

For more complicated conversions such as constructing an L-shaped Dormer, the cost can shoot upto £40,000 to £75,000. It will cost you around £1,250 to £1450 per square metre.

Hip To Gable Loft Conversion

Hip To Gable Loft Conversion

Semi-detached or detached properties are best suited for this type of loft conversion, having hipped roofs.

Here, the hip is extended vertically from the ridgeline to create a vertical wall known as a gable. Mostly, Hip to Gable loft conversions are followed by the addition of dormers to the rear of the property to maximize the space.

One of the hipped roofs is replaced by a vertical brick wall.

Here much of the portion of the roof is altered. The loft conversion is complicated unlike dormer and roof light loft conversions.

Cost of Hip-to-Gable Loft Conversion

The cost is pretty higher than dormer loft conversion as a major part of the roof is altered. The loft conversion cost starts from can £30,000 and can go upto £60,000. Price per square metre varies from £1,500 – £2,500.

Mansard Loft Conversion

Mansard Loft Conversion

Mansard loft conversions give you the maximum living space in your loft area. You can even get a master bedroom with an en-suite that will completely solve your space issues.

Here the roof is completely alerted, so you may be required to take planning permission. Also, the roof is altered from the rear of the property.

The conversion most likely delivers you a flat roof with a 72 degree sloping walls.

Cost of Mansard Loft Conversion

The cost of Loft conversion starts from £40,000 and can go up to £70,000. The average cost of loft conversion per square metre ranges from £1,500 to £2,500

Apart from these, many readymade loft conversions are made on-site and transported directly to the location to be renovated. This significantly reduces labour costs. These can cost around £55,000.

There may be chances that you need to change your roof structure completely. Rebuilding requires additional costs such as designer fees, permission fees and costs incurred from labour and materials.

This type of conversion may cost above £40,000 or starts from £1,550 per square meter.

4. How location can change the loft conversion cost

There are no fixed or standard prices for the building works, the same thing reflects in cost. It has been noted that loft conversion costs are higher in busier and expensive property areas.

On the other hand, you may see a significant decrease in prices in the areas where property prices are lower.

Here are some of the reasons for why loft conversion cost is higher in metropolitan and busiest areas of the city.

  • Site access

In metro cities, the space for parking, scaffolding and machinery is very less. So, more experienced labour and specialized machines are required to handle all this, which increases the cost.

  • Labour Cost

In the areas where the cost of living is high, the daily wages and salaries of labourers are high as well.

  • Transportation Cost 

The production plants are mostly located outside the city. So, due to space constraints, a good distance from the production plants and delivery cost all sum up to increase the overall cost of loft conversion.

Other Loft Conversion Costs 

  • Professional Fees

While planning to undergo any building work, you will have to pay the professional fees apart from your construction costs.

Your property may fall under Permitted Development but you need to follow building regulations. For that, you need to produce the drawings of loft conversion to the building regulation officers.

To ensure that drawings are perceived professionally and to reduce the chances of rejection, you need to approach a professional designer.

Submitting unclear or hazy information can lead to miscalculations and will result in either delaying or rejection of your application.

  • Planning Fees

You may or may not require the planning permission but you will need to file for the Certificate of Lawfulness from your local council. The fee is somewhat around £86 – £100.

If planning permission is required, the expected fee is £172 but could vary.

All the details, procedure and fees for loft conversion are mentioned on the Planning Portal. The fee may differ from project to project and depend on the amount of work and complexity

  • Design Fee

Generally, most loft conversion companies include the design fee in their quotation. It would be around 3%-7% of the total construction cost.

But, in case you’ve hired an architect to design your loft, expect a minimum fee of £2,000 for the planning drawings.

If you’ve also hired a structural engineer to analyse and inspect your joists, ceiling and roofs stability and determining feasibility scenarios for loft conversion, expect a fee of around £1000 to £1,500.

Combining all these costs, it may not sound like a better option to hire every professional individually. Rather you can choose to hire a loft conversion company that will do all the work for you professionally and in the right way.

  • Party Wall Fees 

You may need to get a party wall agreement signed if you share a common wall with your neighbours.

This agreement states that your structure/construction works will not damage or harm your neighbour property in any way.

The cost of the fee is around £700 – £1,000 per neighbour.

  • Building Control Fees 

A building Control certificate is required and can be obtained after completion of the work. The average cost is about £500 plus taxes that turns out to be somewhat around £750.

You can liaise with a government-approved inspection company or approach your local authority for the same. They will inspect your property and on verifying that all the works are carried out in compliance with the rules, the certificate is issued at completion.

  • Interior Fittings cost

You may find your loft conversion cost much higher than you expected. There may be a possibility that you haven’t considered other hidden costs.

There are other costs such as insulation, sanitary ware, basic lighting, fire and waterproofing, installation of windows that add up and raise your budget.

It’s always recommended to discuss all the points with your contractor or company and be very clear on the costs.

6. Other factors affecting loft conversion cost

Apart from the above-stated factors, some other things can raise the cost of a loft conversion. These are:

  • If you have more than one neighbour, you need a separate Party Wall Agreement for each of them. This adds up to the cost. Any disputes may further result in more expenses
  • Your existing loft structure may need some more beams to provide strength and structural integrity to the new space
  • Any constraints on on-site accessibility can further shoot up your costs
  • If your building is old, any structural alterations can result in mishappenings or accidents. Your structure may need to strengthen the joists and beams, only after that actual loft conversion can happen
  • If you are living in a high building or a flat, don’t forget to add the cost of transporting the material to your place, installation and removal of scaffolding etc
  • Going for high-end and premium finishing? Expect a rise in your cost

7. Cost of a loft conversion – Is it worth it?

Loft Conversion is one of the best ways that not only add space to your home but also increase the value of your home by a minimum of 20%.

Whether your family is growing or you are looking to add new space for your office, gym or study, loft conversion offers a plethora of benefits.
