Loft Conversion Prices
The bottom line when planning any building project is ‘How much will it cost’. Loft conversion prices vary from region to region within the UK and, of course, no two conversions are likely to be the same.
But, we can use some ballpark figures and rule-of-thumb.
The first, and arguably the most important, is that by building a loft conversion you should immediately add at least the amount you spend onto the value of your house.
And it just keeps on getting better.
Figures released in July 2006 show that a loft conversion which incorporates a bedroom and en-suite bathroom can add up to 20% to the value of your home.
In London loft conversion prices usually cost up to £40,000 though throughout the UK the average seems to be around the £20,000 - £30,000 mark.
These costs are when employing a specialist loft conversion company and they can be drastically reduced by doing some of the work yourself.
Much of course depends on the type of conversion. For example, a basic storage solution can often be done in just a day or two and there are some specialist loft conversion companies who will, for around £1000, install joists, a new hatch, lighting and a loft ladder in just 24 hours.
But, for a full scale, and well built loft conversion, loft conversion prices are usually somewhere between £14-£40,000.
The following is a guide to the loft conversion prices you could expect to pay (note – figures are estimates which don’t take into account regional variations but still provide a useful guide)
Small Loft conversion to include joists, two roof lights and stairs. Insulated and plaster-boarded, second electrical fix.
£15-£17,000
Medium loft conversion to include joists, two roof lights and stairs. Insulated and plaster boarded, second electrical fix. £18-£24,000
Large loft conversion to include joists, two roof lights and stairs. Insulated and plaster boarded, second electrical fix. £25-£40,000
Storage loft conversion to include flooring, lighting and loft ladder £700-£1000.
For the competent DIY enthusiast there are many companies who will provide a ‘kit’ for the homeowner to install himself with the builder tackling the big jobs such as installing the staircase, floor and roof light.
These DIY kits typically cost from around £5,000 and do represent a huge saving on other loft conversion prices.
Builders will also be able to quote for different parts of the job and, for example, a standard no-frills staircase can be built on site for as little as £500 and there are many companies around the UK who specialise in building loft stairs.
Other estimated loft conversion prices:
Loft stairs (manufactured and fitted) £500-£800 for a traditional straight flight or spiral £1-£2000
Roof lights (supplied and fitted) £500-£750
Dormer (built and glazed) £4-£6000
Loft plans drawn up by an architect or other professional to be submitted as part of a building regulations application £400-£1500 dependent on the complexity of the project.
The above loft conversion prices are a guide and adding extras will obviously increase the cost. Installing an en-suite bathroom for example would probably add £8-10,000 and extras such as insulating walls and ceilings would also add to the budget.
A low cost option could include enhancing the basic storage loft conversion by adding a staircase, roof light, second electrical fix, insulation and plastering which could cost between £6-£12,000
Of course, all circumstances are also different and the homeowner could get an idea of the costs involved by visiting one of the specialist companies who provide an online quotation service.
Another thing to consider is that there are builders who will do loft conversions very much cheaper than the prices quoted above. Costs can be trimmed by not using exterior scaffolding, installing only one small roof light, compromising on materials and circumventing the building regulations.
The advice on this site is to always do things by the book and to employ a specialist loft conversion company – but quality does cost more.
