Building regulations drawings in Islington, £695 fixed
Islington council leaseholders must use the council's own building control and get approval before the landlord decides, and a three-year lapse rule applies to every application. We prepare construction drawings with that order in mind, and check drains, doors and exemptions before the set goes in.
Householder application fee, paid to your council at submission.
Plus the Planning Portal's own charge if the application goes through the Portal: up to £149 including VAT, depending on the application type, and some types have none (source).

What Islington Council asks of a building regulations application
From the council's Building control FAQs (adopted current council page, read 25 October 2026).
- Islington council leaseholders who want to alter their property have to use Islington's Building Control service, and must get building regulation approval before the landlord makes a decision, as part of their lease terms. (source, checked 25 October 2026)
- A porch or conservatory built at ground level and under 30 square metres is exempt if its glazing meets the Part N safety requirements and no alteration is made to the house. Every other extension to a house needs building regulations approval. (source, checked 25 October 2026)
- If work has not started within three years of the deposit of plans, or submission of a building or initial notice, the application is declared void and a new one must be made, with any changes to the regulations since then and a new charge. (source, checked 25 October 2026)
- Islington refers owners building over or near a drain or sewer to its Build Over Agreement booklet, and replacement windows need approval unless a contractor registered with a competent person scheme self-certifies the work. (source, checked 25 October 2026)
- Replacing a flat entrance door in an Islington council leasehold property needs a full plans application, and the new doorset must be a type FD30S with a self-closing device, backed by a fire test certificate and installed to it, with an inspection during fitting. (source, checked 25 October 2026)
What Islington building regulations application drawings have to show
If you are an Islington council leaseholder, the approval comes before the landlord's decision, so the construction drawings and the specification have to be ready earlier than they would be elsewhere. We prepare the sections, structural notes and fire details as a single set, and mark clearly where a flat entrance door or a compartment wall is involved.
For work near a drain we check the sewer position and tell you whether the Build Over Agreement process applies before the set is issued. For a ground-floor porch or conservatory under 30 square metres we confirm the exemption conditions, including the Part N glazing, so you know whether to submit anything at all.
