Loft Conversions – Which Tradesmen to Call

For most of us, having an extra bedroom, bathroom or office within the home would be a welcome addition. One of the best ways to create extra living space and add value to your home is a loft conversion.

The first factor to consider is whether your roof is suitable for a loft conversion in the first place and if so, which type of loft conversion is suitable for your home. Discovering this can be quite complex, as it is largely dependent upon the height and pitch of your roof space. This is really important, and it would be a very good idea to call in the services of a qualified and experienced building surveyor to check this for you.

Loft conversions typically fall into four categories:


The existing shape of the roof is maintained, and skylight windows are inserted into the roof. This is usually the cheapest option and does not usually require planning permission.

Price: Approximately £20,000


A small extension and window are added to the side of the roof, creating extra floor space. This is usually more expensive than a Velux conversion, as more alterations to the roof are required. Dormer loft conversions will also usually require planning permission.

Price: Approximately £25,000

Hip to Gable

An extension is added to one corner of the roof, where the gable wall of the house is extended upwards to the ridge line of the roof. This will provide more floor space and height to one side of the roof. As this involves extending the gable wall of the property, a lot of additional work and planning consent will be necessary.

Price: Approximately £32,000


A large extension is added to both the side and the top of the roof, creating extra floor and roof space. This type of conversion will require significant alterations to the roof, with planning permission required.

Price: Approximately £35,000

The price that you pay for your loft conversion will vary depending upon factors such as where you live, the type of loft of conversion you choose and how you decide to use it. Although it may seem expensive, a good quality loft conversion can add up to 20 percent to the value of your home.

Once the suitability of your loft for conversion has been determined, a number of different tradesmen will be required. A building surveyor and architect will usually be required to help to draw up plans and submit them to the local authority for consent. See our construction directory for some good examples.

Tradesmen, such as carpenters and roofers will be required to make adjustments to the roof joists and beams and to fit windows if necessary. Other tradesmen, such as plumbers and electricians will be needed to fit new plumbing or wiring, or to make adjustments to existing wiring circuits or central heating equipment that may be in your loft already. In addition to this, plasterers, tilers, flooring specialists and other trades may well be necessary depending on what you decide to use your loft conversion for.

Alternatively, a specialist loft conversion company can guide you through every step of the process and arrange most of this work to be done for you. They can also ensure that essential building regulations are followed correctly. Not only will this ensure that your home is safe, but it will also maximize the value of your home when you come to sell it.
