Built-up letters are three-dimensional letters fabricated, usually from metal sheet, with a face and returns joined into a hollow letter typically 50–100 mm deep, then fixed to a wall or sign on locators.

What built-up 3D letters cost in Harrow
Use these figures to budget: £55 to £165 per letter is the guide range, with VAT added on top. Each line in the table is indicative only, and your exact price is confirmed after a survey or once we have looked over the artwork.
| Item | Guide, ex VAT | Inc. VAT (20%) |
|---|---|---|
| Fabricated letter, 300 mm tall | £55 – £165 | £66 – £198 |
| Typical business name (10–14 letters) | £850 – £2,600 | £1,020 – £3,120 |
| Logo or symbol, made to the same depth | £150 – £650 | £180 – £780 |
The metal drives cost first: painted aluminium sits at the lower end, mirror stainless and brass finishes at the top. Letter height, return depth, letter count, stand-off locators, access height and the wall surface follow. Every price is confirmed after survey and an artwork check.

Do you need permission for a sign in Harrow?
Will you need permission? For a non-illuminated sign at your own business address in England, usually not, as long as it stays inside the deemed consent limits: letters no taller than 0.75 m (0.3 m in an area of special control) and nothing above the bottom of a first-floor window. Historic streets need more care. In a conservation area the details matter more, and fixing to a listed building usually needs listed building consent, with fixings into mortar joints rather than brick or stone faces generally preferred. We check with you before anything is ordered, and can prepare drawings and photos for an application, or submit it for you.
