A patio sounds like a simple job. Slabs go down, you’re done. But what’s underneath those slabs is what decides whether your patio lasts fifteen years or starts cracking after two winters. Before you book anyone in, here’s what actually matters.
It’s Not About the Slabs. It’s About What’s Underneath
Skip the ground prep and you’ll pay for it later, just not straight away. A proper patio build starts with excavation to the right depth, then a compacted sub-base (usually MOT Type 1 stone), then a bedding layer, and only then the paving itself. Miss a layer, or don’t compact it properly, and slabs rock, sink, or crack within a couple of seasons. It’s the least visible part of the job and the part that fails first when it’s rushed.
Do You Need Planning Permission for a Patio in Norwich?
Most of the time, no. A ground-level patio is generally permitted development in Norwich. You’ll likely need to check with the council if:
- Your property is listed, or sits in one of Norwich’s conservation areas
- The patio raises ground level substantially near a boundary
- Water from the new surface would drain onto a public path or road
If none of those apply, you can usually go ahead without an application. It’s still worth confirming with Norwich City Council if you’re at all unsure, particularly on older or listed properties.
Drainage Matters More Than Most People Think
Norfolk’s clay-heavy soil doesn’t drain well on its own. A patio needs a gentle fall away from the house, and on some sites, a soakaway or drainage channel to stop water pooling against the walls. Skipping this doesn’t just risk a soggy patch of garden. It can lead to damp problems against the house itself, which costs a lot more to put right than a drain would have.
What a New Patio Costs in Norwich in 2026
Prices vary a lot depending on access, material and how much groundwork is involved, but as a rough guide:
- Small patio (around 15m²), standard access: roughly £80–£140 per m²
- Mid-size patio with drainage work included: roughly £120–£200 per m²
- Restricted access (rear gardens, narrow side passage): add 15–25% for extra labour and material handling
A cheap quote is almost always cheap because something’s been left out underneath. Ask exactly what depth of excavation and sub-base is included before comparing prices.
“Paving and Groundworks Near Me” — Why That Search Matters
Search paving and groundworks near me and you’ll get a mix of results: some are pure paving installers, others do groundwork and drainage as their main trade. The difference matters. A patio isn’t really a paving job, it’s a groundwork job with paving on top. Contractors who only do the surface layer often subcontract the excavation and drainage, which adds a handover point where things can go wrong, or simply get missed.
How to Spot the Best Paving and Landscaping Contractors in Norwich
A good quote should tell you more than a price. Before booking anyone, check:
- Excavation depth and sub-base type are written into the quote, not just assumed
- Drainage falls and any soakaway needs are covered, not an afterthought
- They carry public liability insurance and can show recent, local project photos
- One team handles groundwork through to the finished paving, not two separate handovers
When to Book Your Patio Project
Spring and early autumn tend to be the best windows, when the ground isn’t waterlogged and drying times between stages are shorter. Winter builds are possible but slower, since wet clay takes longer to work with. Booking ahead of the spring rush, over winter, usually gets you an earlier start date.
