Summary
A £20,000 budget for van life in the UK is realistic and workable. The formula is simple: spend 40-50% on a reliable van, 20-25% on the essential conversion (insulation, electrics, bed, kitchen), keep the rest as a safety buffer, and upgrade things like the fridge or heating later when you can afford better.
Start with what you need to survive, then build out from there. Most overlanding YouTubers have vans that cost £40,000+ — but the best van life adventures happen in £8,000 vans with £200 of plywood and a £100 diesel heater.
Can You Really Start Van Life for Under £20,000?
Yes — and thousands of UK van lifers do it every year. A £20,000 budget is realistic for a complete setup: buying a used van, converting it yourself, and kitting it out with everything you need to live on the road. The key is knowing where to spend and where to save.
This guide breaks down exactly what £20,000 buys you in 2026, with real UK prices for vans, materials, and essential gear.
The Budget Breakdown
1. The Van: £4,000 – £10,000
Your biggest single expense. The golden rule: spend more on a reliable base vehicle and less on the conversion. A rusty van with a blown engine is the fastest way to blow your budget.
Best budget vans in the UK:
| Model | Typical Price | MPG | Notes |
|---|---|---|---|
| Ford Transit (2006-2013) | £4,000-£8,000 | 30-35 | Most parts cheap, any mechanic can work on them |
| Mercedes Sprinter (2005-2012) | £5,000-£10,000 | 28-32 | More rust-prone but better build quality |
| VW Crafter (2006-2016) | £5,000-£9,000 | 30-34 | Shared parts with Mercedes, good reliability |
| Citroen Relay / Peugeot Boxer / Fiat Ducato | £3,500-£7,000 | 30-38 | Most common base for UK conversions, Fiat engines are solid |
| LDV Convoy / Maxus | £2,000-£4,000 | 25-30 | Ugly but cheap. Parts are harder to find |
What to look for:
- Full service history is worth paying £500-1,000 extra
- Rust on sills, wheel arches, and floor pans — structural rust is a dealbreaker
- Cambelt change interval (every 5-6 years or 100k miles)
- MOT history check online (free on GOV.UK)
2. Insulation & Flooring: £300 – £800
| Material | Cost (LWB van) | Best For |
|---|---|---|
| PIR/Celotex rigid foam | £150-250 | Best insulation per £; cut to fit between ribs |
| Sheep's wool (Thermafleece) | £200-400 | Eco-friendly, good acoustic; more expensive |
| Kampa 3-in-1 (foil + foam) | £100-200 | Quick to install, decent warmth |
| Plywood floor (12mm) | £80-150 | Cheapest option; paint or vinyl over it |
| Vinyl flooring | £30-80 | Easy to clean, looks good |
Tip: Use PIR board for walls and ceiling, sheep's wool for cavity fill. Skip spray foam — it's expensive and makes future repairs impossible.
3. Electrical System: £400 – £1,200
You don't need a full Victron setup on a budget. These are the essentials:
- Leisure battery: 100Ah LiFePO4 (£200-350) or 110Ah lead-acid (£80-120). Go LiFePO4 if you can stretch — lighter, longer life, more usable capacity.
- Battery charger: CTEK MXS 5.0 (£70) or a basic 12V charger (£25)
- Split charge relay: £30-50 (or a VSR for £60-80)
- DC fuse box: £20-40
- USB sockets, cigarette lighter, lights: £30-50
- Cabling, fuses, connectors: £50-100
Total: ~£400 for a basic setup with lead-acid, ~£800-1,200 with LiFePO4 and solar.
4. Bed Frame: £100 – £300
A simple plywood bed frame with storage underneath is cheap and effective:
- 2× sheets of 18mm plywood (£60-80)
- Timber for frame (£20-40)
- Foam mattress cut to size (£60-150 from Foam for Comfort UK)
- Slats or plywood base (£20-40)
The "rock and roll" bed (folds into seats) costs £500-1,500 and eats into your budget. A fixed bed with garage underneath is cheaper and more practical.
5. Kitchen: £200 – £500
Keep it simple:
- 2-burner gas hob (Campingaz or similar): £30-60
- Gas bottle + hose + regulator: £40-60
- 10L water container with tap: £15-25
- Coolbox (12V): £50-150 (or use a good quality cool bag for £20)
- Kitchen unit (plywood + worktop): £50-150
- Sink (second-hand or basic): £15-30
A full compressor fridge (like a Waeco or Alpicool) costs £250-500 and is worth it if you can stretch. Start with a coolbox and upgrade later.
6. Heating: £100 – £400
UK winters demand heating. The budget options:
- Diesel heater (Chinese, e.g., Vevor/Autoterm clone): £100-180. These work well if installed properly. Genuine Autoterm/Eberspacher: £500+.
- Gas heater (Propex): £300-400 installed. Safe, reliable, but more expensive.
- Portable gas heater: £30-60. DANGEROUS — produces CO and condensation. Only use with ventilation.
Don't skip heating. A £100 Chinese diesel heater will keep you alive in January. Learn the installation — it's not hard.
7. Water System: £50 – £150
- Jerry can with tap: £10-20
- 12V submersible pump: £15-30
- Pipework + fittings: £15-30
- Waste water container: £10-20
- Shower option: A portable camping shower (£20-50) or USB rechargeable (£15-30)
You don't need a pressurised system with accumulator tanks on a budget build. A simple 12V pump with a switch is fine.
8. Toilet: £30 – £200
Minimum: A bucket with a toilet seat (£10-20) and compostable bags. Serious option: A Porta Potti (£80-150 second-hand) or a simple composting bucket setup.
Skip the expensive composting toilets (Air Head, etc. — £800-1,200) on a budget build. A Porta Potti or bucket system is perfectly fine.
Sample £15,000 Build (What I'd Actually Do)
| Item | Cost |
|---|---|
| Ford Transit 2008 LWB, 120k miles, good MOT history | £5,500 |
| PIR insulation + plywood + vinyl | £400 |
| 100Ah LiFePO4 battery + DC-DC charger | £400 |
| Split charge relay + cabling + fuse box | £150 |
| Lights, USB sockets, 12V sockets | £60 |
| Plywood bed frame + foam mattress | £200 |
| 2-burner gas hob + 10L water | £80 |
| Coolbox | £80 |
| Diesel heater (Chinese) + installation kit | £140 |
| Porta Potti | £100 |
| Window vents + roof fan (second-hand) | £100 |
| Paint + rust treatment | £150 |
| Curtains + blinds | £60 |
| MOT + service + insurance | £700 |
| Total | £8,120 |
That leaves £6,880+ for solar panels, a compressor fridge upgrade, a Webasto heater, or just savings for life on the road.
Where to Cut Costs (Without Regret)
Save money on:
- Second-hand everything (Facebook Marketplace, eBay, Gumtree)
- Chinese diesel heaters (genuinely good for the price)
- Plywood instead of birch/poplar (half the price, similar performance)
- Standard mattress foam instead of "campervan" mattresses (same thing, half the price)
- DIY installation of everything (YouTube is your friend)
Don't save money on:
- The base van (buy the best one you can afford)
- Tyres (decent all-seasons, not cheap ditch-finders)
- Leisure battery (LiFePO4 pays for itself in 2-3 years)
- Gas safety (propane leaks kill)
- Insurance (get proper van life insurance, not standard van insurance)
Hidden Costs to Plan For
- Insurance: £300-800/year for a self-build campervan. Specialist insurers include Comfort, Brentacre, and AIB.
- Vehicle tax: £0 (historic vehicle) to £300/year
- MOT: £55/year (from 3 years old)
- Services: £200-400/year
- Breakdown cover: £80-200/year (get one that covers you in the van)
- Gas bottles: £20-40 per refill
- Campsite fees: £5-30/night
