How much does a house extension cost in Leicester?
Costs vary by size, specification, and site access, but a rough guide and next steps can be discussed at a free, no-obligation site visit. Get in touch to arrange a quote.
Do I need planning permission for an extension in Leicester?
Many single-storey rear extensions fall under permitted development rules and don't need full planning permission, though this depends on your property, its location, and any previous alterations. Even where full permission isn't needed, a lawful development certificate or prior notification is usually recommended so there's written confirmation on file.
Planning permission is handled by different authorities depending on where the property is:
- Properties in Leicester city: Leicester City Council
- Properties elsewhere in Leicestershire: the relevant district or borough council — for example Oadby & Wigston Borough Council, Charnwood Borough Council, or Blaby District Council. Leicestershire County Council's guide explains which applies.
We're happy to talk through what's likely to apply during a site visit, but the council always has the final say.
Will I need to use subcontractors, and who manages them?
Some trades — electrical, plumbing, and similar specialist work — are brought in as needed rather than handled directly. Stuart stays the single point of contact throughout, coordinating and scheduling every trade so the project runs as one job rather than several separate ones. This is standard practice for projects of this size and keeps quality and timing consistent, while still giving you one person accountable for the whole build.
What can complicate a project or add unexpected cost?
A few things commonly affect the price or timeline once work is underway, and it's worth discussing these upfront at the quote stage:
- Unforeseen structural issues once walls or floors are opened up — damp, outdated wiring, or foundations that don't match what's expected
- Changes to planning requirements once the council has reviewed the application, or the need for a party wall agreement with neighbours
- Ground conditions on the specific site, which can affect groundworks and foundations
- Client changes to the design or specification once work has started
A thorough site visit and clear scope before work begins is the best way to minimise surprises, and any changes are always discussed and agreed before proceeding.
