Great guy. Super knowledgeable and able to find solutions to unforseen issues left from previous builders. Would highly recommend!

I started Out Of Hours London while working my job as an S.M.S.T.S site manager and trade supervisor for the principle contractor for Hammersmith and Fulham council after a being in this role for for years dealing with sub contractors and trade staff running large and small projects carrying out surveys and leasing with the resident and leaseholders it became obviously clear i had to start doing this for myself. The Name Out Of Hours London was born from necessity i started doing night time call out and offering appointments outside my normal working hours until enough work came in to enable me to resign. I now enjoy my work and have found a good balance. Naturally i have a number of highly skilled trade staff to call on when required.

Came to quote and completed the work in the same visit. Took the time to properly sort the issue and also picked up on other problems whilst there - the pricing was also very fair despite staying after regular hours. Couldn’t rate highly enough.

Loft Conversion Specialists - what you need to know

  • Garage conversions.
  • Extensions.
  • Roof light conversions.
  • Dormer conversions.
  • Hip-to-gable conversions.
  • Mansard conversions.
sm loft conversion 1

Having a loft conversion is a major piece of work but depending on your circumstances it might well be easier than moving. You’ll gain a substantial amount of space, plus you’ll also add significant value to your home.

Costs for common loft conversion jobs

Type of conversion Low High
Roof light conversion £20,000 £30,000
Dormer conversion £30,000 £40,000
Hip-to-gable conversion £25,000 £35,000
Mansard conversion £35,000 £45,000

Can your loft be converted?

If you have a look down your street, that’ll give you the quickest indication of whether your loft can be converted. If there are similar houses with loft conversions, it’s very likely you can have one too.

You should also look at the internal height of your loft as it currently is. If the tallest part of it is at least 2.2m-2.5m you shouldn’t have any issue converting.

A typical roof is supported with either trusses or rafters, which are easily identified by just looking in the loft. Rafters follow the edge of the roof, meaning the space below it is empty. Trusses criss-cross through the loft.

Trusses cost more to convert because extra structural support is needed to replace them.

Lastly you should also think about how much space you have below the loft. A staircase will have to be built so that the loft conversion is habitable, which will take up some space in the room below – can you afford to lose that space?

What’s a roof light conversion?

If your loft is pretty spacious already, and could function as a room without needing to extend the walls, then a roof light conversion could be for you. It’s the least disruptive conversion and will turn your loft into a habitable room. You’ll get windows installed, as well as a floor and a stairwell, plus they’ll obviously spruce the room up with any necessary insulation, plasterboard and decorating.

What’s a dormer conversion?

These are the most common and most suitable for a sloped A-shaped roof. The extension simply protrudes from the slope of the roof to create extra space.

What’s a hip-to-gable conversion?

A ‘hip’ roof is where your roof slopes down towards the side of your property, usually on a detached or semi-detached house. Much like a dormer, this side of the slope is extended to create a new room.

What’s a mansard conversion?

Mansard conversions basically make all sides of your roof vertical, which is the most expensive conversion, but also results in the most space.

The qualifications your loft conversion specialist needs

If your loft conversion specialist has any sort of membership or qualification that isn’t covered below, it’s always a good idea to just ask for proof. They might also have a card from the Construction Skills Certification Scheme

Trade bodies

 The first thing you can do when considering a loft conversion specialist is to check they’re registered with an official trade body. There are several in the UK such as The Chartered Institute of Building (CIOB) and the Federation of Master Builders (FMB). These bodies have criteria that must be met in order to become a member, demonstrating the extent of their experience.

For example, with CIOB membership they look for things like degrees, technical qualifications, military training and educational backgrounds.

 You can see a full list of bodies on the British Associations site, or with TrustMark.

Planning permission for loft conversion jobs

Planning permission isn’t normally needed, but permission is required where you extend or alter the roof space and it exceeds certain specified limits and conditions.

Insurance for loft conversion specialists

Public liability insurance

Your loft conversion specialist definitely needs to have public liability insurance, which will cover you and them if someone gets hurt or if the property is damaged.

Insurance-backed warranties or guarantees 

You can get this as part of the cost of the work, if your specialist offers it. Check exactly what’s covered - it should include the cost of finishing or fixing the work if there are any issues.

Home and contents insurance

If you have home or contents insurance, check with your insurer to make sure you'll be covered while the work is going on. You might have to pay more for your insurance during and after the work. Your insurer will probably want to know what builder you’re using and what insurance they have.

Building regulations for loft conversions

These are the key things you’ll need to be aware of, but it’s best to consult the Planning Portal for full, up-to-date info.

Fire safety - you’ll need fire-resistant doors for the new room, along with mains-powered smoke alarms.

Floors and beams – all structural floors and supports will need to be sufficient for the new room.

Sound insulation between rooms and walls.

Stairs – you need a permanent staircase rather than a ladder or retractable staircase, so that the room can be easily escaped from in case of a fire.

Walls – new walls will have to support existing or new roofs where existing supports have been removed.

Questions you should ask a loft conversion specialist

  • Do they have public liability insurance and what does this cover?
  • Are they registered with a competent person scheme and will they take care of all planning permissions / building regulation approvals?
  • Do they offer insurance-backed warranties?
  • How long have they been trading for?
  • Can they give you up to 3 references of recent work they’ve completed?
  • Do they use sub-contractors or their own employees?
  • What experience do their sub-contractors/employees have and are they covered by insurance?
  • Will they give a guarantee/warranty for the work and how long does it last?
  • Will they source all materials and equipment?
