Council archive fees & timescales
An official building control reply letter and certificate copy from Islington costs £143 for the standard 10-day service (or £387 for a 48-hour reply), payable upfront before the team begins checking the file.
Restrictions on who can request records
Building control records are private. Islington releases them only to the owner or a solicitor acting for them, and requires proof of identity and ownership.
How far back records go
Islington retains building control records for 15 years and may not hold anything older.
Why Islington Council often isn't the archive that holds your certificate
Building work can be signed off by the council, by a private approved inspector, or (for replacement windows, boilers, rewires and solar panels) by an installer registered with a competent person scheme. Only council-inspected work is held by Islington Council. For everything else, the certificate sits with FENSA, CERTASS, Gas Safe, NICEIC, NAPIT, ELECSA or MCS — which is why our search checks all 8 schemes alongside the council.
Protect your indemnity insurance option: Building Regulations indemnity policies are usually written on the basis that the council has not been contacted about the missing certificate. See why. When you order with My Certs, you can tick public register check only in Step 2 so we check Islington Council's online register and all 8 schemes without ever emailing or phoning the council.
