Which Barnet postcodes does this permitted development scheme service cover?
Every Barnet postcode district we draw in, the stock that dominates
it and the authority that validates a permitted development scheme there. Barnet fees below are the
statutory England rates for 2026, not permitted development scheme estimates.
| Postcode | Area | Dominant stock | What it means for a permitted development scheme |
|---|
| HA8 | Edgware / Burnt Oak | 1930s semi-detached, post-war flats | Edgware / Burnt Oak sits wholly inside HA8, so Barnet Council validates every permitted development scheme submitted from an HA8 address. |
| N10 | Muswell Hill | Edwardian villas, 1930s semi-detached | A permitted development scheme in Muswell Hill may land with Haringey Council or Barnet Council — N10 crosses the boundary, and the N10 policies map decides it street by street. |
| NW2 | Cricklewood / Neasden | Edwardian villas and terraces | NW2 straddles a boundary: Cricklewood / Neasden addresses fall to Brent Council or Barnet Council or Camden Council, so confirm which authority validates the permitted development scheme before submitting NW2 drawings. |
| N2 | East Finchley | Edwardian terraces, 1930s semi-detached | N2 covers East Finchley only; Barnet Council handles the permitted development scheme. |
| N3 | Finchley Central | 1930s semi-detached, Edwardian villas | N3 covers Finchley Central only; Barnet Council handles the permitted development scheme. |
| N11 | New Southgate / Bounds Green | 1930s semi-detached dominates; Edwardian villas in Muswell Hill | New Southgate / Bounds Green is split at N11. Either Barnet Council or Enfield Council can determine a permitted development scheme here, so the N11 address is checked against both policies maps first. |
| N12 | North Finchley / Woodside Park | 1930s semi-detached, Edwardian villas | A permitted development scheme at an N12 address in North Finchley / Woodside Park is determined by Barnet Council under its own Local Plan policies for North Finchley / Woodside Park. |
| N20 | Whetstone / Totteridge | 1930s semi-detached, Edwardian villas | A permitted development scheme at an N20 address in Whetstone / Totteridge is determined by Barnet Council under its own Local Plan policies for Whetstone / Totteridge. |

Does Barnet planning policy restrict a permitted development scheme?
How designation changes a Barnet permitted development scheme: Barnet Council’s own list names 20 conservation areas, including Golders Green, Monken Hadley, Hampstead Garden Suburb. Inside any of them a Barnet permitted development scheme 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. Hampstead Garden Suburb sets the tone for Barnet casework.
Barnet permitted development status: there is no borough-wide direction from Barnet Council, so a permitted development scheme at a N2 address is normally still permitted development. We certify that with a £274 Lawful Development Certificate rather than leaving a Barnet sale to argue it later.
Barnet housing stock: 1930s semi-detached dominates; Edwardian villas in Muswell Hill, Finchley; Garden Suburb Arts & Crafts in Hampstead Garden Suburb; post-war flats in Colindale. Suburban outer-London borough; permitted development used heavily; Hampstead Garden Suburb has its own residents' trust with additional design controls. Read that before choosing a permitted development scheme route in Barnet — construction, not postcode, sets what is achievable.
Which neighbouring authorities border Barnet?
- Brent — adjoining Barnet, with 22 conservation areas centred on NW2. A permitted development scheme on the far side of the Barnet line is determined by Brent Council, so the Barnet quote for permitted development schemes is checked against Brent guidance before it is issued.
- Camden — adjoining Barnet, with 40 conservation areas centred on NW1. A permitted development scheme on the far side of the Barnet line is determined by Camden Council, so the Barnet quote for permitted development schemes is checked against Camden guidance before it is issued.
- Haringey — cross the Barnet boundary and Haringey Council takes the permitted development scheme instead, applying 29 conservation areas of its own around N4. We re-price permitted development schemes at the Barnet edge because Haringey policy and Barnet policy rarely align on permitted development scheme depth.
- Enfield — the Enfield boundary runs against Barnet, so a permitted development scheme a street from Barnet is decided by Enfield Council instead. Enfield runs 22 conservation areas across EN1 and its neighbours, which is why permitted development schemes priced for Barnet are re-checked against Enfield policy whenever the Barnet address sits on that edge.
