Laptop repair or replacement? A cost-based decision guide

Your laptop is broken, and you're trying to decide whether to fix it or replace it. Here's the framework we use in the workshop when someone asks for an honest second opinion.

The 50% rule (as a starting point)

The simplest guide: if the repair costs more than 50% of what a used replacement of the same spec would cost, lean toward replacement.

A broken laptop with a £120 repair, where a comparable working used laptop would cost £300? Fix it — 40% is below the line.

A broken laptop with a £180 repair, where a comparable used one is £250? That's 72% — usually not worth it unless other factors are unusual.

But the details matter. Let's unpack them.

Step 1 — What's the actual repair cost?

Get a firm quote before you decide, not an estimate. Independent repair workshops should write the quote clearly: specific fault, specific fix, specific price. Ideally:

• Free diagnosis (so you know you've got an accurate quote, not a guess).
• No-fix-no-fee (so a surprise "it's worse than we thought" doesn't cost you).
• Written quote before work starts.

A shop that won't give a firm price before starting is a red flag — walk away.

Step 2 — What's a used replacement actually worth?

Check eBay "Sold" listings (not "asking" — the asking price is fantasy). Filter to working units of the same make and model. Take the median of 10-15 sold prices. That's your realistic replacement cost.

Rough 2026 UK guide:

| Laptop class | 1-2 years old | 3-4 years | 5-6 years | 7+ years | |--------------|---------------|-----------|-----------|----------| | Budget consumer (HP 15, Acer Aspire, Lenovo IdeaPad) | £250-400 | £150-250 | £80-150 | £40-80 | | Mid-range (Lenovo ThinkPad, Dell Latitude, HP EliteBook) | £400-700 | £250-400 | £150-250 | £80-150 | | Premium / gaming (Dell XPS, ASUS ZenBook, Razer Blade) | £600-1200 | £350-600 | £200-350 | £100-200 |

Step 3 — What does the repair actually buy you?

Most laptop repairs restore the laptop to working order but don't fix underlying age. Examples:

• DC jack swap on a 5-year-old laptop: £70 of work, but the battery is probably tired, the thermal paste is dried out, the drive is slowly failing. You've fixed the visible fault but the laptop is still 5 years old.
• Liquid spill clean on a 1-year-old laptop: £150 of work, and you've got a 1-year-old laptop back. Value preserved.
• Screen replacement on a 6-year-old laptop: £180 of work. The laptop is worth £120 when working. You lose money on the repair economics, but if you need this laptop for some specific reason (licensed software, older OS compatibility), £180 may still be less than the alternative.

A repair on a young laptop is usually great value. A repair on an old laptop often isn't, unless paired with an upgrade that adds life.

Step 4 — Combine the repair with an upgrade

This is where older laptops come back into contention. A £70 repair plus a £50 SSD upgrade = £120 spent, and the laptop feels new. An old laptop with a spinning hard drive (HDD, not SSD) is crippled by the drive — an SSD upgrade gives 5× perceived speed improvement, and it's often the single most impactful upgrade you can do.

Typical upgrade pricing while we have it open anyway:

• SSD swap (old HDD → new SSD): £50-100 fitted including the drive depending on capacity.
• RAM upgrade (if the laptop has socketed RAM): £30-60 fitted including the sticks for 8 GB → 16 GB.
• Battery replacement (if health is below 70%): £70-120 fitted for common models.

A 6-year-old laptop with a £70 repair + £60 SSD upgrade + £40 RAM upgrade = £170 total. If that laptop is comparable to a £250 replacement and you've added 3-4 years of life, the repair maths suddenly looks very different.

Factors that push toward repair

• Licensed or obscure software that won't easily re-install on a new machine (old CAD packages, specific versions of Adobe, industry-specific tools).
• Specific hardware compatibility — a particular port, a specific keyboard layout, a discrete GPU that's hard to find in current laptops.
• Data risk. Replacing a working-but-failing laptop is easier than retrieving data from a dead one. A £100 repair now beats a £500 data-recovery quote later.
• Environmental values. Keeping a laptop going for another 3-4 years is measurably greener than replacing it.
• Business tax position. Repairs are immediate expenses; replacements are capital purchases that depreciate over 3-5 years. For a sole trader or small business the repair can be more tax-efficient in the current year.

Factors that push toward replacement

• Multiple simultaneous faults. Screen + battery + hinges all broken = costs add up fast. Each individual repair might pass the 50% test, but together they fail.
• Laptop is already 7+ years old with tired everything. Even if you fix the current fault, another failure is likely in 6-12 months.
• Drop or structural damage to the chassis. A cracked body never becomes uncracked; keyboard, trackpad and display seating are all affected.
• Spec has dated out of usefulness. If the laptop originally shipped with 4 GB RAM and 32 GB eMMC storage, no repair makes it fast. Replace and move on.
• The new equivalent is massively better. Current entry-level £400 laptops are often better than £600 laptops from 5 years ago.

When "just replace it" is wrong

The number one regret we see is people scrapping perfectly-repairable laptops because "well, it's old". A 5-year-old ThinkPad, Latitude or EliteBook with a £60 fix is worth keeping. Business-class laptops from 2019-2021 are genuinely excellent machines, still competitive with current entry-level, and spare parts are abundant.

The number one regret we see going the other way is spending £300 fixing a £400 laptop that was tired in multiple ways — getting 6 more months out of it before the next fault.

When to send it in

We give free diagnosis and honest advice — including "don't repair this, buy a used one, here's what to look for" where appropriate. No-fix-no-fee means advice costs nothing. See our laptop repair service page for typical pricing and turnaround, or get in touch for a quote on your specific laptop.
