How a postal gold buyer actually makes its money
The margin is the gap between what a buyer pays you per gram and what the metal settles at further up the chain. That gap has to cover real costs: refining recovers slightly less than the assayed content, the metal has to be moved or hedged quickly because the price moves, and there are testing, postage, insurance and staff costs on every parcel whether you sell or not. A buyer with no shopfront has fewer of those costs, which is why postal and high-street figures differ, see why high-street buyers tend to pay less.
A margin is legitimate and every buyer has one. A fee charged on top of the margin is a second bite, and it is the second bite that is worth finding before you post. That is why the useful question is never “do you charge a fee?” on its own. It is “what will you pay me per gram for what I actually hold, and does anything come off that figure?” One number, and whether anything is deducted from it.
The eight places a deduction hides
| Where it hides | What to ask |
|---|---|
| A rate quoted as a percentage of spot | Which spot price, in which currency, taken at what time? A percentage is not a price until the base is fixed and dated. |
| Per-pennyweight or per-troy-ounce quoting | Convert everything to pounds per gram before comparing. One troy ounce is 31.1035 grams; one pennyweight is 1.5552 grams. A “high” per-pennyweight rate can be a low per-gram one. |
| Return postage on declined lots | What does declining cost me in total, including postage and any handling charge? |
| Assay, handling or administration fees | Is anything charged at any stage, whether I sell or not? Get the answer in writing. |
| Weight rounding | How is weight recorded, and to how many decimal places? Rounding a mixed lot down to whole grams quietly removes weight you own. |
| Carat treatment of mixed lots | Is each item weighed and priced at its own carat, or is the whole lot averaged down to the lowest carat present? |
| Stone, clasp and solder deductions | Are non-gold parts identified and measured, or is a flat percentage taken off the gross weight as an estimate? |
| Minimum thresholds | Is there a minimum weight or value below which nothing is paid, and what happens to items below it? |
Why percentage-of-spot quotes are hard to compare
Percentage quotes sound transparent and are the hardest form of quote to check. A percentage has to be applied to the fine metal content, not to the gross weight of the piece. Nine-carat gold is 37.5 per cent gold by weight, so a gram of 9ct contains 0.375g of fine gold; 18ct is 75.0 per cent, so a gram contains 0.750g. A percentage-of-spot quote therefore has to be run through the fineness and the weight before it becomes money, and the two buyers quoting the same percentage may be quoting against different spot snapshots, taken at different times, in different currencies.
The only comparison that means anything is pounds per gram, of the carat you actually hold, on the same day. Ask both buyers for that figure and the percentages become irrelevant. The difference between a headline market price and the figure a scrap buyer pays is explained in spot price versus scrap price, and you can sanity-check any figure yourself with the gold and silver calculator.
The five questions that surface every fee
- What will you pay me, in pounds per gram, for 9ct (or whichever carat you hold), today?
- Is anything deducted from that figure before I am paid, and what is it called?
- What does it cost me if I decline, including return postage?
- How is my weight measured and rounded, and will the written offer show it?
- Will the written offer show, per item, the purity found, the weight and the rate used?
A buyer who answers all five in writing has effectively published its fee structure and you can compare it against anyone else. A buyer who answers in percentages, ranges and generalities has not, and that is information too. Asking costs nothing and no reputable buyer will object.
What the law says about disclosing charges
Since 6 April 2025 the unfair commercial practices rules sit in Part 4 of the Digital Markets, Competition and Consumers Act 2024, replacing the Consumer Protection from Unfair Trading Regulations 2008. The Competition and Markets Authority guidance (CMA207, Unfair commercial practices, gov.uk) defines a commercial practice to include an act or omission by a trader relating to the supply of “a consumer’s product to the trader or another person”, so a business buying your gold is inside the regime, not outside it.
Price and how it is calculated is material information under those rules, and the guidance treats information given unclearly, untimely or inconspicuously as omitted. A charge that only appears after your parcel has been opened is the textbook case. This is general information rather than legal advice; if you think a charge was concealed, the escalation route is set out in what to do if something goes wrong.
What GoldPaid charges
Nothing. The Royal Mail Special Delivery label is free, the XRF assay is free, the written offer is free, and the tracked return if you decline is free. There is no assay fee, no handling fee, no administration fee, no return charge and no minimum weight or value. GoldPaid makes its money on the margin between the figure paid to you and the trade settlement, which is why the written offer sets out the purity found, the weight and the rate used for every item rather than presenting a single lump sum. The full method is on how we value gold, and postal cover is on postage and insurance.
Common questions
Do postal gold buyers charge for testing?
Reputable ones do not. Testing is a cost of doing business and is covered by the margin. If a buyer charges an assay, handling or administration fee, ask whether it applies when you decline as well as when you sell, and get the answer in writing before you post.
Should I have to pay return postage if I decline?
No. A free tracked return is what makes a no-obligation valuation genuine. A return charge is small in absolute terms and large in effect, because it makes accepting a poor offer feel cheaper than refusing it.
How do I compare two gold buyers fairly?
Convert both quotes to pounds per gram for the exact carat you hold, on the same day, and ask both whether anything is deducted from that figure. Percentages, per-pennyweight rates and per-troy-ounce rates are not comparable until converted.
Is a percentage of spot a good deal?
It depends entirely on which spot price, at what time, and whether the percentage is applied to the fine gold content or the gross weight. Without those three facts a percentage tells you very little. Ask for the pounds-per-gram figure instead.
Why is the offer lower than the gold price I saw online?
Published gold prices are for pure, refined, investment-grade metal. Jewellery is an alloy that has to be tested, refined and recovered, and it usually contains solder, stones and clasps that are not gold. The gap between the two is the subject of the spot versus scrap guide.
