Pricing, honestly

Areas we cover

London Heroes covers all 33 London boroughs around the clock. Choose yours for the local picture, including what your council requires from landlords.

Windows, doors & locks questions, answered

My uPVC door won't lock unless I lift the handle hard — is that a big job?

Usually not: it's typically alignment (a seasonal shift) or a worn gearbox in the multipoint lock. Alignment is a quick adjustment; a gearbox is a standard replacement part. Both are far cheaper than a new door — and an honest professional will tell you which you need.

Are your locksmiths vetted differently?

Everyone passes the same 15 checks — but security work adds the right-of-access rule above, and the platform's job record means every entry job has a documented, payment-protected trail.
