Every Havering postcode district we draw in, the stock that dominates it and the authority that validates a building regulations package there. Havering fees below are the statutory England rates for 2026, not building regulations package estimates.
| Postcode | Area | Dominant stock | What it means for a building regulations package |
|---|---|---|---|
| RM4 | Havering-atte-Bower | 1930s semi-detached dominates Hornchurch and Upminster; post-war in Harold Hill and Romford; Victorian in older Romford centre | Havering-atte-Bower sits wholly inside RM4, so Havering Council validates every building regulations package submitted from an RM4 address. |
| RM5 | Collier Row | 1930s semi-detached | RM5 covers Collier Row only; Havering Council handles the building regulations package, and Collier Row case officers apply the RM5 conservation-area map. |
| RM7 | Romford / Rush Green | Victorian terraces, 1930s semi-detached, post-war flats | RM7 covers Romford / Rush Green only; Havering Council handles the building regulations package, and Romford / Rush Green case officers apply the RM7 conservation-area map. |
| RM11 | Hornchurch / Emerson Park | 1930s semi-detached | RM11 covers Hornchurch / Emerson Park only; Havering Council handles the building regulations package, and Hornchurch / Emerson Park case officers apply the RM11 conservation-area map. |
| RM12 | Hornchurch / Elm Park | 1930s semi-detached | A building regulations package at an RM12 address in Hornchurch / Elm Park is determined by Havering Council under its own Local Plan policies for Hornchurch / Elm Park. |
| RM13 | Rainham / Wennington | 1930s semi-detached | RM13 covers Rainham / Wennington only; Havering Council handles the building regulations package, and Rainham / Wennington case officers apply the RM13 conservation-area map. |
| RM14 | Upminster / Cranham | 1930s semi-detached, Edwardian villas | Upminster / Cranham sits wholly inside RM14, so Havering Council validates every building regulations package submitted from an RM14 address. |

Roof pitch, wall build-up and plot depth change every few Havering streets, and each one changes what a building regulations package can achieve at that address.
How designation changes a Havering building regulations package: Havering Council maintains 15 conservation areas, including Upminster, Hornchurch, Rainham Village. Inside any of them a Havering building regulations package cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Rainham Village sets the tone for Havering casework.
No blanket Article 4 over Havering: Havering Council has not withdrawn permitted development across Havering, so a building regulations package outside a Havering conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a RM1 owner wants on file.

Direct answers to the questions Havering homeowners ask every week about building regulations drawings.
Start a free quote →In Havering, you can submit building regulations applications to either Havering Council's in-house Building Control (LABC route) or to a private approved inspector. Both routes produce the same legally-valid completion certificate. We submit to whichever suits your project and builder.
The building regulations fee for a Havering project is set by scope: a straightforward extension or loft is the baseline, while HMOs, basement conversions and flat splits need more detailing and coordination. Structural calculations are priced by the intervention — a single beam is far less than a full loft or underpinning package. See our fees.
Yes — every habitable loft conversion in Havering (and across England) requires Building Regulations approval covering fire escape, floor structure, insulation and staircase. This is independent of whether you also need planning permission.
Part L of the Building Regulations sets minimum energy-efficiency standards — insulation, glazing U-values, air permeability, heating efficiency. New extensions in Havering must meet the 2025 uplift (Future Homes Standard transition). We include full Part L calculations and a compliance statement in every Complete package.
Once submitted, Havering Council Building Control reviews Full Plans within 5–8 weeks. Approved inspectors typically review in 2–4 weeks. On-site inspections run through the build — typically 6–10 visits depending on scope.
In Havering, building regulations are required for: loft conversions, extensions, structural alterations, roof replacements, new openings in walls, and any work to a flat. Some minor works (like-for-like replacements, small porches) are exempt. We confirm at the free site visit.
A completion certificate from Havering Council Building Control (or an approved inspector) confirms your works comply with Building Regulations. It is essential for selling or re-mortgaging — lenders and conveyancers require it. We manage the inspection sequence and close out sign-off as part of every Complete package.
Extensions and loft conversions in Havering that change the building's energy characteristics require an updated EPC (or SAP/SBEM calculation as part of Part L compliance). We include Part L calculations in every Complete and Bespoke package.
