Permitted Development & Lawful Development Certificates

Many lofts, single-storey rear extensions and garden rooms can be built under permitted development (PD) rights — a national grant of planning permission — without applying to the council. We confirm your project qualifies with a Lawful Development Certificate so you have certainty.

What is permitted development?

Permitted development (PD) rights are set out in the Town and Country Planning (General Permitted Development) Order 2015 (as amended). They give you a national grant of planning permission to extend or alter your home within specific limits — so you don't need to make a planning application, provided you stay within the rules.

What usually qualifies

  • Single-storey rear extensions within depth limits (typically up to 3m for a terraced or semi-detached house, 4m for a detached — or larger under the prior-approval scheme).
  • Loft conversions within volume limits (around 40m³ for terraced houses, 50m³ for semis and detached), including most rear dormers.
  • Garden rooms, home offices and outbuildings within size, height and use limits.
  • Porches, rooflights and many minor alterations.

Exact limits depend on your house type and what's already been added — we check your specific case.

When permitted development does NOT apply

  • Flats and maisonettes (PD rights generally don't apply).
  • Listed buildings, and many works in conservation areas or under an Article 4 direction.
  • Where PD rights have been removed by a planning condition (common on newer homes).
  • Anything exceeding the size, height or coverage limits.

Why get a Lawful Development Certificate?

An LDC isn't legally required, but it's the formal way to prove your project is lawful. It protects you against future enforcement action and is almost always asked for when you sell or remortgage. For the modest fee, it removes all doubt — which is why we recommend it on every PD project.

Timescale

We prepare the drawings and supporting statement in around 1–2 weeks. The council then determines a Lawful Development Certificate within a statutory 8 weeks — so most PD projects are confirmed within 2–8 weeks.

Fees

The council's LDC (proposed use) fee is half the householder planning fee — indicatively around £150, but it is set by government and changes, so we confirm the current rate. Our design & planning fee for a single loft or 3m rear extension starts at £1,600 (see our pricing). Building Regulations approval is a separate process and cost.

Documents you'll typically need

  • Completed LDC application form
  • Location plan (1:1250)
  • Site / block plan (1:500 or 1:200)
  • Existing floor plans & elevations
  • Proposed floor plans & elevations
  • Statement showing compliance with PD limits
  • The council fee

Common questions

Do I definitely need a Lawful Development Certificate?

No — permitted development is lawful without one. But an LDC is the only way to formally prove it, and buyers, solicitors and lenders almost always ask for it. We strongly recommend it.

What if my project is just over the PD limits?

You have two options: scale the design back within the limits, or apply for householder planning permission. For larger single-storey rear extensions there is also a "prior approval" route (the larger home extension scheme) that we can use in many cases.

Can permitted development rights be removed?

Yes — by a planning condition (common on newer estates), by an Article 4 direction in a conservation area, or on flats and listed buildings. We always check the planning history of your property first.

The other planning routes

Planning rules and statutory fees are set by the UK Government and your local council, and they change over time and vary by area and property. The figures here are indicative for early-stage guidance only and are not a substitute for formal advice — Virtue confirms the exact route, requirements and current fees for your specific property as part of our service.
