Caravan Act, PD & Full Planning Explained

Granny Annexe Planning Permission in
Accrington

A granny annexe in Accrington can go up three genuinely different ways, as a mobile home under the Caravan Sites Act 1968, as an incidental outbuilding under permitted development, or through a full planning application, and which one actually applies depends on your specific plans. We check this properly before you commit to anything.

The Three Routes For A Accrington Granny Annexe

A granny annexe in Accrington can follow three genuinely different routes. A structure that meets the legal definition of a caravan under the Caravan Sites Act 1968, capable of being moved by road in one or two sections and within maximum dimensions of 20 metres by 6.8 metres with an internal height of 3.05 metres, can often be sited without planning permission provided it remains ancillary to the house.

An outbuilding used incidentally to the enjoyment of the house, a home office, gym, or storage, can fall under Class E permitted development, but the moment it includes genuine sleeping accommodation used independently, it’s no longer considered incidental, and permitted development stops applying.

Where neither route fits, a full planning application is the reality for Accrington properties, and we confirm this honestly rather than assume. A Accrington annexe needing full planning permission usually needs both, our Building Regulations drawings in Accrington service covers the technical compliance side, and our structural calculations in Accrington service covers the engineering detail.

How We Help in Accrington

Every Accrington annexe enquiry starts with establishing the real facts, is the structure genuinely mobile within Caravan Act limits, is it staying incidental to the house, or is it a self-contained dwelling, since that shapes the whole route.

From there, we prepare exactly what your Accrington project needs, whether that’s a Lawful Development Certificate confirming caravan or permitted development status, or a full planning application.

Structural and building regulations input runs alongside the planning process for Accrington annexe projects, whichever route applies.

The Real Requirements For Accrington Granny Annexes

We tell Accrington families honestly whether their annexe genuinely qualifies for the Caravan Act or permitted development routes, rather than defaulting every enquiry to a full application.

Getting the self-containment question right matters more than almost anything else for a Accrington annexe, and we assess this honestly rather than assume either way.

Structural and building regulations detail is built into every Accrington annexe project from the start, whichever planning route applies. If you need help with a granny annexe, give us a call on 0330 133 5316 or fill in the form below.

Granny Annexe Planning Permission FAQs for Accrington

Do I need planning permission for a granny annexe in Accrington?

It depends on three things, whether the structure genuinely qualifies as a caravan under the Caravan Sites Act, whether it stays incidental to the house under permitted development, or whether it’s a self-contained dwelling, which almost always needs a full application in Accrington.

What is the Caravan Act route for a Accrington annexe?

Under the Caravan Sites Act 1968, a structure qualifies as a caravan if it’s capable of being moved by road in no more than two sections, and doesn’t exceed 20 metres in length, 6.8 metres in width, or 3.05 metres in internal height, Accrington annexes meeting this can often avoid planning permission if they stay ancillary to the house.

Can I use permitted development for a Accrington annexe?

Only if it stays genuinely incidental to the house, Accrington outbuildings under Class E permitted development cannot be separate, self-contained living accommodation, the moment sleeping facilities are used independently, permitted development stops applying.

What counts as a self-contained annexe in Accrington?

A Accrington annexe with its own bedroom, bathroom, and kitchen, used independently of the main house rather than as shared accommodation, is generally treated as self-contained, which usually means full planning permission is needed.

Do I need a Lawful Development Certificate for my Accrington annexe?

We recommend it, even where your Accrington annexe genuinely qualifies as a caravan or permitted development, a Lawful Development Certificate gives you written confirmation rather than an assumption that could cause problems later, particularly when selling.

Can you handle planning and building regulations for my Accrington annexe?

Yes, we handle the full picture for Accrington annexe projects, the planning route, whichever applies, and building regulations compliance, as one coordinated service.
