Surplus Radiators UK: Column, Panel and Designer at Clearance Prices
Radiators are the second-fastest surplus turn after PIR. Showrooms rotate stock quarterly, plumbers change specs mid-job, and homeowners upgrade en masse when boilers get replaced. Result: designer column radiators at £80–£180 that retail for £400+.
What to check
- Pressure test if the seller can — 3 bar for 5 minutes
- Look for internal corrosion at the tapping — a dark stain means sludge
- Verify BTU output matches your room load
- Confirm the valve size (typically 15mm or 22mm)
Best value formats
Type 22 double-panel radiators offer the highest BTU/£ in surplus. Vertical column radiators dominate the designer end — often ex-showroom with minor scuffs to the top rail.
Frequently asked questions
+Are surplus radiators guaranteed?
Rarely — but a pressure-test and visual inspection catch 95% of issues. Budget £30–£50 for a re-flush before installation.
+Do I need thermostatic valves?
Building Regs Part L requires TRVs on new installs. Add £8–£15 per rad if not included.
