Honesty section

What it doesn't cover.

The things below sit outside the package, either because they're a different profession (Party Wall surveyors, builders) or because not every project needs them. We'll flag what applies to you before you book.

Planning permission application (most lofts are permitted development; we advise per project)
Party Wall award fees (paid to surveyors directly)
Building Control submission fee (paid to the council)
On-site construction or project management
Listed building or conservation area consents (priced separately if needed)

Common questions

What people usually ask before booking.

Do I need planning permission for a loft conversion?

Most lofts go through under permitted development, which means no planning application is needed, you go straight to Building Control. There are exceptions (conservation areas, flats, very large dormers), and where a planning application is required we manage and submit it for you (£199 admin fee). We give you the building regs drawings and structural calcs for Building Control, which you or your builder lodge. We tell you which side of the line your project sits on before you commit.

How long does the drawing pack take?

14 working days from the site visit to the finished submission pack as standard. The £450 expedited add-on cuts that to 7 working days.

What if my builder asks for changes once we start?

Two rounds of revisions are included. Anything beyond that is £55/hr, quoted in writing before any work happens.

Do you also handle the Party Wall notices?

We give you written guidance on what notices you need, when, and to whom. Issuing the formal notices and any subsequent award is a Party Wall surveyor's job, we'll recommend two or three we trust if you don't already have one.
