Below are the rates UK cost guides and installers actually publish, then the part that decides where your own garage lands inside them. We have put the numbers first because that is what you came for. The thing to hold onto as you read: the resin is the cheap part, and the grinding underneath it is what separates a floor that lasts from one that peels.
What a resin garage floor costs in the UK
| Garage | Typical installed total | Where it comes from |
|---|---|---|
| Single, about 18m² | £1,000-£2,500 | Surface Specialists gives the full band; Liberty Floor Solutions (£1,300-£1,400) and JD Flooring (£1,500-£1,800) both sit in the middle of it |
| Double, about 32m² | £1,800-£4,000 | Surface Specialists; JD Flooring quotes £1,800-£2,100 for a standard epoxy floor, with the top of the band being decorative work |
| Poor slab rather than good | add £150-£300 | JD Flooring, taken from the gap between their own good-slab and poor-slab garage prices |
Cost per square metre, by system
| System | Published UK range | Where it comes from |
|---|---|---|
| Basic coating, one colour | £25-£60 per m² | Evo Resin Flooring, UK Trades Awards, ProCalculator. Thin, single or two coats |
| Self-levelling epoxy | £60-£130 per m² | Checkatrade, UK Trades Awards and ProCalculator give an identical band. Checkatrade puts the average at about £100 per m² |
| Flake or quartz broadcast | £100-£150 per m² | ProCalculator, NearMeTrades |
| Metallic pour | £100-£160 per m² | NearMeTrades, ProCalculator |
| Grinding and prep | £15-£30 per m² | ProCalculator; UK Trades Awards adds £5-£20 per m² on top of product cost. Domestic rates: commercial jobs over 100m² fall to £3-£6 |
One figure worth pausing on. Prep at £15-£30 per m² is, on a small garage, a serious share of the whole job, and it is the line a cheap quote deletes. That is not a detail. It is the difference between the two outcomes in the callout below.
Why there is no single price per square metre
A chunk of any garage floor cost is fixed setup: getting the crew and grinder to site, prepping the slab, masking and cutting in the edges. Those costs are much the same whether the garage is small or large, so on a single garage they spread across fewer square metres and push the rate per square metre up. A double or triple garage usually works out lower per square metre than a single. Comparing two quotes on rate alone, without knowing what each includes, tells you little.
What drives a garage floor price
| Cost driver | Why it moves the price |
|---|---|
| Garage size | Single, double or triple: fixed setup costs (grinder, crew, masking) spread across more square metres, so bigger garages usually cost less per m² |
| Slab condition | Grinding is standard; cracks, pitting, oil contamination and patching all add prep time |
| The finish | A solid colour is the simplest; flake sits above it; a full metallic pour is the most involved |
| Damp or moisture | A slab with moisture may need a damp-proof coat before the floor goes down |
| Anti-slip and coving | Grip aggregate and coving the resin up the wall add a little material and time |
| Access and clearing | A garage that has to be emptied or is hard to get kit into takes longer |
Read down that list and most of it is prep and finish, not the resin itself. That is the part cheap quotes tend to skip, and it is exactly what decides whether the floor lasts.
The prep is the hidden cost, and the whole point
Why one "resin floor" costs more than another
Resin floors are graded by how much material actually goes down, and it is a big range. A thin floor seal, the DIY tin of garage paint, is only around a tenth of a millimetre thick and sits at the bottom of the scale. A proper decorative floor, a flake or quartz system, is a multi-layer build several millimetres thick: primer, a coloured base coat, the broadcast flake or quartz, and one or more clear sealing coats. You are paying for the number of coats and the thickness of the build, which is exactly what makes the difference between a floor that shrugs off a working garage and a coating that wears through. Two quotes can both say "resin floor" and mean very different amounts of material, so it is worth asking what system and how many coats.
The other quiet cost is moisture. Many older garage slabs were laid with no damp-proof membrane, or one that has since failed, so a proper job tests the slab for moisture before anything goes down. If it reads high, a damp-suppressing coat is needed first, or the finish will bubble and lift as ground moisture pushes up through it. It is an extra layer of work you cannot see in the finished floor, but skipping it is a common reason a cheap floor fails. Curing matters too: a cold, unheated garage in winter slows the cure right down, which is one reason a fast-curing system can be worth the extra on a British garage.
Which finish, and what it means for cost
Finish is the lever you control. A solid colour is the simplest and most budget-friendly; a flake floor adds the chips that hide marks and give grip; a metallic pour is the showpiece and the most involved to lay. Our guide to the best resin floor for a garage and the garage floor ideas page help you weigh look against budget.
Want a real number for your garage?
Tell us the garage size and the state of the slab, and we will come and take a look, then send one fixed price for the whole job in writing.
Reading a cheap quote
A low quote is not automatically bad, but ask where the saving is. The usual answers are no proper grinding (a coat rolled onto an unprepared slab that peels under a hot tyre), a thinner build, or a large upfront deposit. We agree the whole price in writing before any work starts, with no obligation to go ahead. If a number looks too good, the prep is the first thing to check.
How it compares with the DIY options
A tin of garage floor paint is cheaper up front but sits on the surface and lifts, as we set out in resin versus garage floor paint. Loose tiles avoid the mess but trap dirt at the joints, as we cover in resin versus garage floor tiles. A bonded resin floor costs more than either but outlasts both, which is usually the real comparison. For the wider picture across all floor types, see our resin flooring cost guide.
So what should you do?
Get a written, fixed-price quote from someone who has seen the garage and the slab, and make sure it spells out the grinding and prep as well as the resin. That is the only way to know what your floor will actually cost. We quote garage floors free and in writing across Leicestershire.
About this guide
Who wrote this
This guide is written by the Obsidian Resin team. We quote and lay garage resin floors across Leicestershire, so we price these week in, week out and see how much the slab condition swings the final figure.
Where these figures come from
Every range on this page is a rate published by a named third party, checked on 2026-08-29. The sources sit next to each figure rather than asking you to take a number on trust, including where a figure rests on a single source and should be read as indicative rather than settled. One honest gap: no UK cost guide we could find publishes a rate for polyaspartic, despite plenty of installers offering it. It sits alongside high-build polyurethane at £70-£150 per m², but that is a neighbouring product, not a quoted polyaspartic price, and we would rather say so than make one up.
Why these are market rates and not our price
These are what the UK market charges, which is what you need in order to judge a quote. They are not an Obsidian quote. We do not publish a headline rate of our own, because until someone has seen your slab it would be a guess that moves on the day. You get one fixed price for your actual garage, in writing, before anything starts.
Frequently asked questions
- How much does a resin garage floor cost?
- A single garage of about 18m² costs £1,000-£2,500 installed in the UK, with most jobs landing between £1,300 and £1,800. A double garage of about 32m² costs £1,800-£4,000. Where you sit in the range depends on the condition of the slab and the finish: a solid colour over sound concrete is the cheap end, a metallic pour over a slab needing repair is the top.
- How much is epoxy garage flooring per square metre?
- £25-£60 per m² for a basic single-colour coating, £60-£130 per m² for a proper self-levelling epoxy (Checkatrade puts the average at about £100), £100-£150 per m² for a flake or quartz system, and £100-£160 per m² for metallic. Grinding and prep adds £15-£30 per m² on top where it is quoted separately.
- Does a double garage cost twice as much as a single?
- No, usually less than twice. A single runs £1,000-£2,500 and a double £1,800-£4,000, so the total roughly doubles at the top end but not at the bottom. The fixed setup and prep are similar for both, so a double works out lower per square metre than a single.
- How much does a polyaspartic garage floor cost in the UK?
- No UK cost guide publishes a polyaspartic rate, which is worth knowing before you try to compare one. The nearest published comparison is high-build polyurethane at £70-£150 per m², and polyaspartic generally sits in or slightly above that band because it cures fast enough to finish a garage in a day. Treat any single quoted figure as that installer's price rather than a market rate.
- How much does it cost to grind a garage floor before coating?
- £15-£30 per m² on a domestic garage, covering diamond grinding or shot blasting plus cleaning. Commercial jobs over 100m² drop to £3-£6 per m² because the setup cost spreads further. On a small garage this is a real share of the total, and it is the line a suspiciously cheap quote has usually removed.
- What makes one garage floor quote cheaper than another?
- Usually the prep. A cheaper quote often means no proper diamond grinding (worth £15-£30 per m²), a thinner build, or a large upfront deposit. A poor slab properly dealt with adds £150-£300 to a garage job. The resin is the easy part; the grinding and crack repair beneath it are where cost and durability both sit.
- Do you ask for a deposit?
- Usually not. The fixed written price covers the whole job, so nothing is due until it is finished. On a bigger job we may ask for a deposit before booking materials, agreed in writing beforehand, never sprung on you.
