How to choose between them

  • Check the registration yourself. Trade body memberships are public, and each body's own register confirms them in a minute.
  • Get three quotes on the same specification. Written down, split into labour, materials and anything structural. Most people compare a total against a total and end up choosing between two different jobs.
  • Ask what is not included. Making good, waste removal, scaffolding and VAT are the four that turn a cheap quote into an average one.
  • Never pay a large deposit up front. Materials in advance is normal. Half the total before anyone turns up is not.

Loft conversions in Doncaster: common questions

Do I need planning permission for a loft conversion?

Usually not. Most fall under permitted development if you stay within 40 cubic metres for a terrace or 50 for a semi or detached, do not go above the existing roof ridge, and use materials in keeping. Mansards and anything on a flat or in a conservation area normally do need permission.

How long does a loft conversion take?

Six to eight weeks for a dormer once work starts, plus four to eight weeks beforehand for drawings, structural calculations and building control. Scaffolding usually goes up a week ahead.
