I Spent £3,200 on My Patio Last Year — Here's Everything I Wish I Knew First

I want to be straight with you from the start. I am not a professional landscaper. I am not a garden designer. I am a 43-year-old homeowner in Leeds who spent the better part of 6 months researching a patio project, eventually spent significantly more than I originally budgeted, and ended up with something I am genuinely proud of. But there are things I wish someone had told me before I started  -  honest, practical things that no one's Instagram post or YouTube video quite covered properly.

This is that account. Use it before you start your own project.

Where I Started: The Budget and the Plan

My initial budget was £2,500. I arrived at this number by reviewing product pages and speaking with a neighbour who completed a patio two years ago. I thought it was realistic. It wasn't  -  but not because I was naive. It was because I hadn't accounted for everything.

My garden measures approximately 32 square metres at the back of a 1990s semi-detached in Leeds. It had an existing concrete slab base that was cracked in several places and looked genuinely grim. The plan was simple: break out the old concrete, relay a proper sub-base, and put down new paving. Job done.

The job was not, as it turned out, quite that simple.

Choosing the Paving: Where I Almost Went Wrong

I started looking at Indian sandstone because the price per square metre was considerably lower than porcelain. I'd seen plenty of beautiful sandstone patios online, and in gardens I'd visited, and I liked the natural variation in colour. Kandla Grey kept coming up as the default recommendation  -  which is for good reason, as I later learned.

But something kept nagging at me. We have a five year old daughter and a three year old Labrador called Arthur. Arthur is enthusiastic in ways that frequently involve mud, and our daughter's relationship with ketchup is, let's say, ongoing. Maintenance was going to be a real-world concern, not just a theoretical one.

I spent about three weeks going back and forth before ordering samples of both Indian sandstone and porcelain. I put them outside and looked at them in different lights over a week. And when I saw the Manchester Midnight porcelain sample in afternoon sunlight  -  deep charcoal, slightly blue-black at the edges  -  that was it. Decision made.

The porcelain was more expensive per square metre. But the maintenance argument was real. Arthur has now been using that patio for nine months and it has never, not once, looked dirty for more than an hour after rain. I made the right call.

The Costs I Didn't Account For  -  All Five of Them

Here is where the budget started to stretch. These are the things I hadn't properly factored in:

1. The Skip

Breaking out a 32 square metre concrete slab produces a significant quantity of rubble. I thought I'd manage with a few trips to the tip in my car. I was wrong. One skip, £145. I hadn't budgeted a penny for it.

2. Sub-base Material

I'd budgeted for the paving slabs and not much else. The sub-base  -  Type 1 MOT compacted hardcore  -  adds up fast. For my area, I needed about four bulk bags. That came to £160 including delivery. Again, not in my original calculations.

3. Extra Slabs for Cuts

I ordered what I calculated to be the exact quantity I needed. My installer (a one-man operation recommended by a neighbour) told me immediately to order another 15%. I resisted because I was trying to control costs. By day two of laying, I was short. The reorder  -  same product, smaller quantity, second delivery  -  cost me £180 more than if I'd ordered the extra upfront. The math on this is brutal: always order the first time enough.

4. The Channel Drain

My garden slopes very slightly toward the house. Not dramatically, but enough that after a heavy rain there was always some pooling at the patio edge near the back door. My installer pointed this out on day one and strongly recommended a channel drain. I decided to add it. Drain plus fitting: £210. Absolutely worth it  -  but completely absent from my original budget.

5. The Installer's Day Rate Premium for Porcelain

Porcelain is harder to cut than Indian sandstone. It requires a good quality wet saw, slower cutting speeds, and more care to avoid chipping the edges. My installer charged a premium for porcelain work  -  about 20% more per day than he would have charged for sandstone. Across a two-and-a-half-day project, that was an additional £150 or so. Completely reasonable  -  the work is genuinely more demanding  -  but not something I'd anticipated.

The Full Cost Breakdown

So what did it actually cost? Here's the real number with everything included:

•       Manchester Midnight porcelain slabs (including second order): £1,140

•       Sub-base material and delivery: £160

•       Sand and cement for mortar bed: £85

•       Jointing compound (brush-in): £65

•       Edging setts (granite, 30 linear metres): £195

•       Skip hire: £145

•       Channel drain and fitting (material only): £210

•       Installer labour (2.5 days at adjusted porcelain rate): £900

•       Miscellaneous (sealant, cleaning equipment, a snapped blade): £90

•       TOTAL: £2,990  -  plus a follow-up visit to re-grout one section: £210

•       FINAL TOTAL: £3,200

That's £700 over my original estimate. Every single pound of that overspend was predictable with better planning. None of it was waste  -  it was all necessary. I just hadn't planned for it.

What Went Really Well

I want to be equally clear about the things that went right, because this project was genuinely a success.

The paving itself is extraordinary. Manchester Midnight in 900x600mm looks like something from a high-end garden design magazine. It photographs beautifully. It's transformed a space we barely used into one we use constantly from April to October. Arthur does his worst and a quick hose-down restores it completely. My daughter has already dropped ketchup on it twice and both times it cleaned off without a trace.

The installer I used was excellent. He was meticulous about the drainage gradient, spent time on the edging details that really finish the job properly, and was honest throughout about what was and wasn't necessary.

The project added real value to our home. An estate agent who visited us for an unrelated reason told us that the patio, combined with the general garden condition, probably added around £8,000–£12,000 to the property value. Given that we spent £3,200, the return on investment is frankly exceptional.

The Five Things I'd Tell Anyone Starting This Process

1.    Order samples. Don't commit to any material without having a physical sample in your actual garden in your actual light conditions. I nearly chose a different product based on photos alone. Seeing it in person changed my decision.

2.    Budget 25% more than your initial estimate. Not because projects always go wrong, but because there are always costs you haven't thought of. A 25% buffer means you're not stressed at the end.

3.    Order 15% extra slabs, not 10%. The pain of running short and paying for a second delivery is disproportionate to the modest cost of over-ordering slightly.

4.    Sort drainage before you choose your paving. It affects the installation design fundamentally. Don't discover you need a channel drain on day one.

5.    Don't cut corners on the installer. Three quotes, check reviews, ask to see previous work. The gap between a good and a mediocre installation is visible every single day for the life of the patio.

Frequently Asked Questions

How long does a porcelain patio last?

Quality porcelain paving, properly installed on a solid sub-base, should last 25–30 years or more with minimal maintenance. The material itself is effectively inert  -  it doesn't degrade, fade, or absorb water. The weak points are the jointing compound and the sub-base, not the slabs.

Is Manchester Midnight suitable for cold northern UK climates?

Yes, absolutely. Porcelain's near-zero water absorption makes it essentially frost-proof. It's an excellent choice for any UK climate, including northern England and Scotland, where freeze-thaw cycles are more frequent.

How long did the patio installation take?

Two and a half days for 32 square metres, including the edging work. This is roughly typical for an experienced professional. DIY installation would take considerably longer.

Should I get planning permission for a patio?

For most rear garden patios, planning permission is not required. There are exceptions  -  listed buildings, conservation areas, patios that affect drainage, and some rules about raised decking. Always check your local council's requirements if you're unsure.
