If your engine is overheating, the first thing you’ll hear is the word "radiator." Replacing it can feel pricey, but knowing what you’re paying for makes the process far less stressful. In this guide we break down the typical radiator price in the UK for 2025, the bits that add to the cost, and a few tricks to keep your wallet happy.
On average, a brand‑new radiator for a common Italian model runs between £120 and £250 for the part alone. Luxury or high‑performance cars can push that figure up to £500‑£800. Labour is the other big chunk – most garages charge £80‑£150 for fitting, depending on how easy the job is and whether additional work (like flushing the system) is needed. If you add coolant, a drain‑plug seal, or a new thermostat, expect another £30‑£70.
So a typical replacement for an average family hatchback ends up around £250‑£350 total. For a sports sedan it’s easy to hit £700‑£900 when you add premium parts and higher labour rates.
Car make and model. Rare or performance cars use specialised radiators that are lighter, have more cores, or use aluminium instead of plastic. Those designs cost more to manufacture and ship.
Part source. OEM (original equipment manufacturer) parts match the factory spec and usually sit at the top of the price range. Aftermarket options can be 20‑40% cheaper but vary in quality. Check reviews and ask the shop about warranty terms.
Location and garage type. Independent workshops often have lower hourly rates than franchised dealers. However, a dealer may offer a guarantee on both part and labour that an independent shop can’t match.
Additional services. A coolant flush, pressure test, or replacing an old hose bundle adds labour time. Some garages bundle these services into a “radiator replacement package” for a flat fee, which can be a good deal if you need several things done at once.
Season and demand. Prices tend to jump in summer when overheating issues surge, and drop in colder months when fewer people need a new radiator. If you can wait, ask the shop if they expect any seasonal discounts.
To keep costs down, start by getting at least three quotes. Ask each garage to break down parts, labour, and any extras so you can compare apples to apples. Don’t forget to ask whether the quoted price includes VAT – some smaller shops forget to add it in their initial estimate.
Finally, consider doing a little of the prep yourself. Draining the coolant and removing the old radiator can shave an hour off the labour bill. Just make sure you follow safety steps: let the engine cool, wear gloves, and dispose of old coolant responsibly.
Whether you’re fixing a daily driver or a prized Italian sportscar, knowing the typical radiator price and what drives it helps you avoid surprise invoices. Use this guide as a checklist, ask the right questions, and you’ll get a fair price without compromising on quality.
