What is the difference between built-up and flat-cut letters?

Built-up letters are hollow, fabricated with separate faces and returns, so they can be 50–100 mm deep or more. Flat-cut letters are cut from one solid sheet, usually 5–10 mm thick. Built-up letters have more presence and share their construction with illuminated letters; flat-cut letters cost less.

Can built-up letters go on cladding?

Yes, in most cases. Metal and composite cladding needs a fixing that suits the panel system, such as rivnuts, through-bolts to a backing rail, or a mounting rail behind the letters. We ask the building owner about the cladding before drilling, because some systems restrict penetrations.

Why is there a price range for built-up 3D letters rather than one figure?

Because jobs vary. The guide of £55 to £165 per letter + VAT spans small, simple work at one end and larger, more involved work at the other. Size, material, finish, access, design time and any consent drawings push the figure up or down. A survey or artwork check lets us fix the price for your job in Carshalton.

When could work on built-up 3D letters go ahead in Carshalton?

Fitting is typically scheduled once three things are in place: you have approved the proof, the materials are made or delivered, and any consent the job needs has been granted. For many jobs that is typically a few weeks from approval; illuminated or larger fabricated signs typically take longer, and consent decisions run to their own timetable.

Can non-lit built-up letters be lit later?

Not easily. Illuminated letters need translucent faces or open backs, internal LED modules, drain holes and cable routes designed in from the start. If lighting is a possibility, we can quote halo-lit or face-lit letters now, or plan spotlights for a non-lit set.

Can you handle built-up 3D letters for a business in Carshalton?

Yes. Smart Signs covers Carshalton and the rest of Greater London as part of a UK-wide service. You send photos and rough sizes, we arrange a survey if the job needs one, then you receive a proof to scale and a fixed written price. Nothing is made or fitted until you have approved both.

Do you need permission for a sign in Carshalton?

Advertisement consent in England comes from the Town and Country Planning (Control of Advertisements) (England) Regulations 2007. A sign is either excluded from control, has deemed consent, or needs express consent from the council's planning department. For a plain, unlit sign on your own premises, deemed consent usually applies when characters are 0.75 m tall or less (0.3 m in an area of special control) and the top edge is below the first-floor windows. Conservation areas need more care, and a listed building usually needs listed building consent as well; working without it can be a criminal offence. We confirm the route before you commit, and can prepare the drawings for an application or submit it for you.
