How much does planning permission really cost in North Kesteven?

Most homeowners in North Kesteven start their planning research by Googling the application fee. They find £548, nod, and move on. What they don't realise is that number is often the smallest line on the bill — and whether you even get to pay it depends on a maze of property-specific variables that most people never see coming. WhatCanIBuild exists precisely because that maze looks different for every address.

The £548 is just the beginning

The headline fee for a householder planning application is £548. On top of that, if you submit online through the Planning Portal, a service charge of £75.83 + VAT applies to applications attracting fees over £100. That's before you've paid anyone to draw plans, write a supporting statement, or respond to the council's queries.

Architect or technician fees for drawings can run into the hundreds or thousands depending on project complexity. If your application needs a heritage statement, a flood risk assessment, or an ecological survey — each triggered by where your property sits, not just what you want to build — those costs layer on top. Most homeowners don't realise these are even required until they're already mid-application.

North Kesteven's planning landscape is unusually complex

This is a district where the local context does a lot of the work — and not always in your favour.

With 36 conservation areas spread across the district, a significant number of streets carry heritage restrictions that limit what external alterations are permissible, even on unremarkable-looking properties. Whether your house falls inside one of those boundaries changes the rules entirely. And it's not just about being in a conservation area — it's about which one, what the local character appraisal says, and what the council has historically approved or refused on your street.

Then there's the Lincolnshire Wolds AONB boundary. Properties near that edge sit on Article 1(5) land, where permitted development rights are restricted in ways that catch homeowners completely off guard. The boundary doesn't follow obvious landmarks, and being a few hundred metres one side or the other can mean the difference between needing permission and not.

1,007 listed buildings are recorded across the district. If yours is one of them — or if it's in the curtilage of one — the rules change again, and the fees for listed building consent work differently too.

What the fee guide won't tell you

Knowing the application fee tells you almost nothing useful. The questions that actually matter are: what has the council approved for similar projects near your address? What were the conditions attached? Have applications been refused on your street, and why?

That's the gap WhatCanIBuild fills — not just flagging that you're near a conservation area or an AONB boundary, but showing you what that actually means for your specific project type based on real decision data from your area. The difference between knowing a constraint exists and knowing how it plays out in practice is where most homeowners get caught out.

North Kesteven's typical decision time is 8 weeks, but that clock only starts once your application is valid. An incorrect fee, a missing document, or an unexpected constraint flagged at submission can push your project back months — and cost you far more than the application fee ever would.

The best way to understand your real costs before committing to anything is to check your specific address with WhatCanIBuild — so you know what you're walking into.
