Three variables matter when choosing a cash house buyer, and they don't always pull in the same direction. Speed determines how quickly the seller can move on. Fees determine how much of the headline figure actually arrives in the bank account. Reliability determines whether the deal completes at all. A company that scores well on two of the three is worth considering. A company that scores well on all three is rare enough to warrant its own assessment.
The five companies below are the operators we've found to handle all three variables consistently. Each has been assessed on the same criteria: published completion timelines, fee transparency, and verifiable track record across multiple transactions.
Comparison Table

|---|---|---|---|---|
| 1 | Sell House Fast | From 7 days | None (all legal fees covered) | NAPB + TPO; 300+ purchases per year; guaranteed sale |
| 2 | Upstix | 7–28 days | No estate agent fees (legal fees not covered) | NAPB + TPO; 4,000+ transactions |
| 3 | Yes Homebuyers | 14–21 days typical | None (all legal fees covered) | £1,000 deposit guarantee against offer changes |
| 4 | Vivo Property Buyers | 7–14 working days | None (legal fees covered) | NAPB + TPO + FSB; 96% of formal offers reportedly held at initial offer level |

1. Sell House Fast
Sell House Fast buys properties directly across England and Wales, with a fee structure that absorbs all legal costs and a stated completion window from seven days. The combination of speed, no-fee model, and offer reliability puts the company in the upper bracket of the UK quick sale market.
The reliability comes from the operational model. Sellers receive a preliminary offer immediately, can verify proof of funds before any commitment, and retain the right to walk away at any stage. Once the formal offer is accepted, it holds through to completion without survey-stage renegotiation. The company completes 300+ purchases per year, including problem properties and complex cases, and the after-sale support runs around the clock for sellers managing time-sensitive transactions.
Key features:
- Proof of funds available on request before any offer is signed.
- Buys over 300 properties per year.
- Immediate preliminary cash offer.
- Free professional valuation, no obligation.
- Customer-first approach with the seller setting the terms.
- Members of the NAPB and The Property Ombudsman.
- No-obligation offers; the seller can back out at any point.
- 24/7 customer service team.
2. Upstix
Upstix operates from London with institutionally backed funding and a technology-led valuation system. Initial valuations are generated through an online portal, then verified by estate agent partners and RICS surveyor inspection. Completion can be achieved in as little as seven days.
The company is registered with the NAPB and The Property Ombudsman. Upstix charges no fees to the seller and offers a distinctive "second payment" structure in which the seller receives a share of any resale surplus. Reliability is strong given the institutional funding model, though the company is comparatively young, having been founded in 2021.
3. Yes Homebuyers
Yes Homebuyers, based in Chester and operating since around 2015, completes sales within two weeks as a standard timeline. The company purchases properties directly with its own funds and absorbs all transaction costs, including legal fees.
Yes Homebuyers focuses on time-sensitive transactions and problem properties. The reliability record is solid within its operating bracket, though the company doesn't publish a fixed percentage rate for its offers.
4. Vivo Property Buyers
Vivo Property Buyers offers an unusually transparent fixed rate of 85 percent of estimated current market value, with all legal fees, clearance, cleaning, and refurbishment costs included. Completion windows are typically 7 to 14 days after the formal offer is accepted.
Registered with The Property Ombudsman, the company commits to a fixed price post-acceptance, eliminating the survey-stage renegotiation that affects less reliable operators. The 24/7 contact point and in-house legal team support consistent delivery on the stated timelines.
5. UK Homebuyers
UK Homebuyers, founded in 2007 and based in London, completes purchases within a few weeks using its own cash reserves. The company issues formal offers within 24 to 48 hours of initial enquiry, with no fees charged to the seller.
Registered with The Property Ombudsman, UK Homebuyers targets sellers in time-sensitive situations and applies a current-market-value valuation methodology. The 2007 founding date provides a longer trading history than some of its competitors, supporting the reliability assessment.
How to Compare Cash Buyers on Speed, Fees, and Reliability
The headline figure on a cash buyer's website rarely tells the whole story. A more useful comparison evaluates each operator against the specific dimensions that affect the seller's actual outcome.
- Stated minimum completion time vs. average completion time. Most buyers advertise a 7-day minimum, but average completions are typically two to four weeks. The realistic average matters more than the marketing claim.
- Full fee disclosure. Legal fees, valuation fees, survey fees, exit fees, and any other deductions should all be itemized in writing before the seller commits. A buyer who can't produce this list is potentially hiding costs.
- Offer reliability through to completion. Operators with a track record of renegotiating after survey should be treated as offering whatever their final figure ends up being, not whatever they quoted initially.
- Proof of funds verifiability. A genuine cash buyer can produce bank statements, audited accounts, or solicitor confirmation of funds on request. Vague responses are a warning sign.
- Industry membership and the consequences of leaving it. NAPB and Property Ombudsman membership provide formal accountability mechanisms. Operators outside these structures have fewer reasons to behave well under pressure.
- Coverage of difficult cases. Buyers who only handle straightforward properties may not deliver when the transaction encounters complications. Operators with a track record on problem properties typically have the operational depth to handle standard ones too.
- Availability outside office hours. Cash sales often involve urgency that doesn't respect working patterns. Buyers reachable only during office hours may not be the right fit for time-sensitive situations.
- A clear escalation route when things go wrong. Even reliable operators encounter issues. The companies worth dealing with have a clear path for resolving disputes, ideally backed by industry ombudsman membership.
The Bottom Line
The best cash buyer for any specific seller depends on the property, the situation, and the timeline. The five companies above all score well on the three core variables, but they differ in their specific strengths. National coverage, regional knowledge, fixed-percentage pricing, surplus-sharing structures, and 24/7 support all matter in different scenarios.
Verifying proof of funds, requesting full fee disclosure, and checking ombudsman membership are the three pieces of due diligence worth completing before signing anything. Reputable buyers don't object to any of them.
FAQs
Which cash buying company is fastest?
The fastest operators can complete in seven days from offer acceptance, assuming the seller's paperwork is in order. Most genuine cash buyers offer a similar minimum window, with average completions typically taking one to three weeks.
Do all cash buyers cover legal fees?
Reputable buyers do. Sellers should verify this in writing before accepting any offer. Operators charging legal fees or surveyor costs are functionally offering less than their headline figure suggests.
How can I tell if a cash buyer is reliable?
Check industry memberships (NAPB and The Property Ombudsman), request proof of funds, look for verified independent reviews, and ask whether the offer is contingent on further inspections. Reliable operators answer all of these clearly.
What's the difference between the largest and smallest cash buyers?
Larger operators typically have more operational infrastructure, broader geographical coverage, and longer trading histories. Smaller operators often have better local market knowledge and more personal service. Neither is inherently more reliable.
Do cash buyers ever pay full market value?
Almost never. Cash offers reflect the buyer absorbing legal costs, completion speed, and resale risk, all of which reduce the headline figure relative to a full open-market sale. Operators claiming to pay full market value should be approached with caution.
Can I get multiple cash offers?
Yes, and most sellers should. Multiple offers establish a realistic price range and provide negotiating leverage. Reputable buyers won't pressure sellers to commit before comparing alternatives.
What's the biggest cost a cash buyer might hide?
Survey-stage renegotiation is the most common. An offer that drops by 5 to 10 percent after survey is effectively a different offer. Sellers should ask directly whether the headline figure is subject to any post-acceptance review.
