What should I fix before selling, and what should I leave?
Published 9 October 2026 · 6 min read · By Evren Ergin
Fix anything a buyer's surveyor is likely to flag, such as damp, roof and guttering faults, electrical faults and pests, then refresh rather than replace, and leave kitchens, bathrooms, extensions and new appliances alone. Before you spend anything, ask competing local agents what your street actually rewards, because that answer costs nothing.
TL;DR
- •Fix what a survey will flag: damp, roof and guttering, electrics, heating and plumbing, and pests.
- •Refresh rather than replace: a deep clean, a neutral coat of paint and new handles beat a new kitchen.
- •Buyers often want to put their own stamp on kitchens and bathrooms, so a full overhaul rarely pays you back.
- •Get free valuations from competing local agents before you spend, so the budget follows evidence and not guesswork.
Research on what pays off before a sale is thin and mostly comes from agents, so treat the figures below as direction and not as a promise. The principle underneath is steady: spend to remove reasons for a buyer to hesitate, and do not spend to impress a buyer who will redecorate anyway.
What does a surveyor-ready house actually mean?
A surveyor-ready house is one where a buyer's survey finds nothing that could be used to cut the price or delay the sale. It is the target for the first round of work. The Home Owners Alliance lists the usual culprits in its guide, updated on 8 October 2026: damp, suspected subsidence, electrical faults, heating and plumbing, roof, tiles and guttering, and infestations.
Fix, refresh or leave: a quick guide (sources: Home Owners Alliance, updated 8 October 2026; ValuQ summary)
| Item | What to do | Why |
|---|---|---|
| Damp, mould, leaks | Fix before listing | Buyers often ask for it to be fixed after the survey, and visible damp can put them off before they offer |
| Electrics, boiler, plumbing | Repair faults, service the boiler, keep the receipt | Safety items come up in surveys and in the buyer's solicitor's questions |
| Roof, tiles, guttering | Fix visible faults | Buyers see the outside before they see anything else |
| Pests | Treat before marketing | A problem found late is a reason to renegotiate |
| Paint, small cracks, loose fittings | Refresh with a neutral coat and tidy repairs | Cheap, and it signals a cared-for home |
| Carpets | Deep clean; replace only if torn | New carpet is rarely recovered in the price |
| Kitchen and bathroom | Paint, regrout, change handles; do not replace a working suite | Buyers often want to choose their own |
| Appliances | Leave unless broken | New white goods are unlikely to be recouped |
| Extension or loft conversion | Leave; consider plans or permission to show potential | Costly and slow, and the buyer may want something different |
1. Find out what your street rewards before you spend
Ask local agents to value the home as it stands and tell you which work, if any, moves the price in your area. Local evidence beats a general rule, and a valuation costs nothing.
2. Fix what a surveyor would flag
Deal with damp, roof and guttering faults, electrical faults, heating and plumbing, and pests. A problem you fix is cheaper than a problem the buyer finds and prices in.
3. Refresh rather than replace
Deep clean, remove limescale, regrout tiles, fill small cracks and apply a fresh neutral coat of paint. Paint worn kitchen cabinets or swap fronts and handles instead of fitting a new kitchen.
4. Tidy the outside
Keep the lawn cut, clear the borders, mend the fence and clean the windows and front door. Buyers form a view of the house from the pavement.
5. Leave the big jobs, and document them
If a roof, rewire or extension needs doing and you will not do it, get two or three builder quotes to show buyers. Selling in poor condition means expecting a lower price, and some homes will only suit cash buyers.
6. Set a spending limit before you start
Choose a figure you are happy never to see again and stop there. The calculator linked below helps you budget the work against what you expect to net from the sale.
Why is a full kitchen or bathroom rarely worth it?
A renovated kitchen costs real money and reflects one person's taste. A buyer who dislikes it still plans to replace it, and now has paid for yours. Agents commonly advise painting or re-fronting cabinets and regrouting bathrooms instead.
Window replacement is a good example of cost running ahead of reward: the Home Owners Alliance puts an average at between £500 and £3,200 per window, so a whole house adds up quickly.
Is it worth doing the work if the market is soft?
A softer market makes careful spending more important, not less. Rightmove reported in August 2026 that new-seller asking prices fell 2% in the month, against a ten-year August average fall of 1.3%, and cut its 2026 forecast from a 2% rise to between 0% and a 2% fall. In a market like that, buyers have choice, so removing reasons to hesitate matters more than adding features.
Time matters too. The Home Owners Alliance gives the average time to reach sold subject to contract as two months, 62 days. If the home has been listed for around that long without an offer, that is the moment to review price, presentation and agent, not to start a major project.
What does it cost to renovate in the first place?
The cost of bringing a dated home up to standard is usually higher than the discount buyers apply to it. A Benham & Reeves study published on 25 April 2022 put the average discount for an unmodernised home at about 4.5%, and the average cost of modernising at about 15.8% of its value. That is one reason that, for most sellers, doing a full renovation before selling does not pay.
That study is from 2022, so use it for the shape of the trade-off, not the current pound figures. A local valuation tells you the current numbers for your street.
How do I find out what is worth doing in my area?
Ask competing agents. ValuQ gives UK homeowners free, side-by-side property valuations from competing local estate agents. You see every valuation on one screen before you speak to anyone, and agents never get your details until you choose. If two agents say a fresh coat of paint and a tidy garden is all the house needs, you have your budget.
Should I repaint before I sell?
Usually yes, if the walls are marked or in strong colours. A fresh neutral coat is generally enough. You rarely need to repaint woodwork or ceilings unless they are in poor condition.
Do I have to fix everything a survey finds?
No. You choose what to repair and what to leave. Problems you leave can be raised by the buyer and negotiated, which sometimes costs less than a full repair in advance. Fixing safety items and visible damp first is the sensible order.
Should I get my own survey before selling?
It can help if you suspect a problem, because you learn the cost before a buyer does. It is a choice, not a requirement.
Does a new kitchen add value when I sell?
Not reliably. Buyers often prefer to choose their own kitchen, so a full replacement may not pay you back. Cabinet paint, new handles and a deep clean usually return more for the spend.
What if I cannot afford to fix a big problem?
Get two or three builder quotes and show them to buyers. Be ready for a lower price, and for a pool of buyers that may be limited to cash purchasers if the home is hard to mortgage.
