A practical, step-by-step guide to buying or selling a home in England and Wales in 2026, covering budgets, mortgages, surveys, searches, exchange, completion, taxes and why deals fail.
Buying or selling a home in England and Wales is a multi-stage project that only becomes legally binding at exchange of contracts. Budget properly, instruct a good conveyancer early, run surveys and searches in parallel with mortgage underwriting, and don’t exchange until finance, legal and timing risks are clear.

This guide is for buyers, sellers and anyone planning a move in 2026. It walks you through the full journey from budgeting to completion, explains where deals commonly fail, and introduces a simple risk framework you can use to decide when it’s safe to exchange.
Disclaimer: This is general information, not legal, tax or mortgage advice. Your solicitor or licensed conveyancer, mortgage adviser and surveyor should advise on your specific circumstances. Firms like North and Broadway (nandblaw.com) can assist in many areas, from conveyancing and leasehold enquiries to coordinating with lenders and managing agents.
Most transactions follow this pattern: prepare, market or search, view, offer, instruct conveyancer, investigate property and finance, resolve enquiries, exchange contracts, complete, then move. Stages overlap; the deal only becomes legally binding at exchange.
A typical transaction follows this broad pattern:
Prepare → market or search → view → offer → instruct conveyancer → investigate property and finance → resolve enquiries → exchange contracts → complete → move
The stages overlap. Searches, surveys, mortgage underwriting and conveyancing should usually run in parallel rather than one after another.
The Most Important Legal Point:
In England and Wales, an accepted offer is normally not legally binding until contracts are exchanged. Before exchange, either party can usually pull out or renegotiate. The transaction can still be affected by a survey, a mortgage down-valuation, legal problems, a broken chain or simply someone changing their mind. After exchange, both sides are contractually committed. Walking away can lead to serious financial and legal consequences.
Official guidance often says the overall process takes about five months on average, but that’s not a guarantee. A chain-free purchase can be quicker, while a chain, leasehold property, title defect or mortgage delay can stretch things out considerably. Current government commentary uses different transaction measures, including around 120 days for an average home purchase and roughly 170 days for a wider transaction measure.
Start with the total cost of buying, not just the price. Include deposit, mortgage fees, legal and search costs, survey, tax, insurance, removals and a contingency. Total moving costs often exceed £5,000 excluding deposit and tax.
Make room in your budget for:
• Deposit
• Mortgage payments and product/arrangement fees
• Conveyancing fees and search costs
• Survey costs
• Mortgage valuation costs (unless covered by the lender)
• Stamp Duty Land Tax (England) or Land Transaction Tax (Wales)
• Buildings insurance
• Removals, storage and temporary accommodation
• Repairs, improvements and furnishing
• Leasehold service charges, ground rent and major works
• A contingency reserve
MoneyHelper notes that legal fees, surveys, mortgage-related costs and other moving expenses can add several thousand pounds. A combined figure of more than £5,000 is possible, but actual costs vary a lot and may exclude the deposit and property tax.
Don’t rely only on a lender’s maximum borrowing figure. A property can be technically affordable but feel financially tight once utilities, insurance, maintenance, tax and service charges are included.
Get a decision in principle to gauge borrowing, but treat it as an estimate, not a guarantee. Full underwriting and valuation happen after your offer and can change the loan amount or lead to refusal.
You might hear terms like Mortgage in principle, Agreement in principle, or Decision in principle. Lenders use these differently, but they generally signal an initial estimate rather than a guaranteed mortgage.
A decision in principle:
• Doesn’t guarantee final approval
• May be based on limited information
• May involve a credit check
• Doesn’t confirm that a particular property is acceptable security
• Doesn’t guarantee that the lender will value the property at the agreed price
After you make an offer, the lender will usually carry out full underwriting and arrange a mortgage valuation. The lender may approve you but still reduce the loan, ask for more information or decline the property.
Viewings should test both condition and future running costs. Look beyond décor, check key structural and services areas, and ask about repairs, disputes, planning and leasehold charges before you offer.
Where possible, check:
• Roofs, windows, doors, walls and visible cracks
• Damp, mould, condensation and ventilation
• Heating system, boiler age and energy performance
• Electrical installation and plumbing
• Drainage, gutters and external ground levels
• Boundaries, access, parking and garden arrangements
• Noise, traffic, transport and neighbouring properties
• Flood, mining, contamination or other environmental risks
• Planned development, road schemes and local changes
• Whether extensions or alterations appear to have the necessary approvals
It’s also worth asking about recent repairs, previous leaks, neighbour disputes, planning approvals, warranties, and the seller’s onward plans. For leasehold properties, check lease length, service charges, ground rent, reserve funds, major works, and freeholder details early.
Offers are “subject to contract” and not binding. Strengthen your position by clarifying chain status, deposit size, mortgage position and flexibility on completion, not just the price.
A seller may prefer a slightly lower offer from a buyer with a short, reliable chain over a higher offer that depends on several uncertain transactions. Ensure the seller confirms exactly what fixtures and fittings are included (e.g. white goods, curtains, sheds).
Instruct a solicitor or licensed conveyancer as soon as your offer is accepted. They handle title, searches, enquiries, contract, exchange, completion, tax and registration. Choose on quality and total cost, not just the cheapest quote.
Your conveyancer will verify identity, review title, check covenants, order searches, raise enquiries, review the draft contract, satisfy lender conditions, arrange exchange/completion, and handle post-completion registration and taxes. North and Broadway (nandblaw.com) handles these day-to-day services, from simple freehold purchases to complex leasehold matters.
A mortgage valuation protects the lender, not you. Commission an appropriate RICS Home Survey (Level 1–3) to understand condition, defects and likely maintenance costs before you exchange.
| Survey Level | Usually Suitable For |
|---|---|
| Level 1 | A basic condition overview of a conventional property. |
| Level 2 | A conventional house, flat or bungalow in reasonable condition. |
| Level 3 | An older, altered, unusual, larger or visibly defective property. |
RICS surveys are primarily visual and do not normally involve destructive investigation. If you’re buying a new-build, consider a snagging inspection to pick up incomplete work.
Standard searches cover local authority, water/drainage and environment. Additional searches may be needed for mining, flood, highways or contamination. Don’t waive searches without understanding the risk to you and your lender.
Your conveyancer investigates title, boundaries, rights, covenants, planning, lease terms and service charges. The seller’s property form is helpful but is completed from seller knowledge and is not a substitute for proper legal work and a survey.
A full mortgage offer is different from a decision in principle. Before exchange, confirm the offer is formally issued, sufficient, valid, conditioned appropriately, and aligned with your completion date.
Do not exchange until finance, survey, searches, legal enquiries, insurance and completion timing are all clear. Exchange is the point where the deal becomes legally binding and pulling out carries real penalties.
Exchange happens between conveyancers and records price, deposit, completion date and special conditions. After exchange, both parties are legally committed; the typical gap to completion is one to four weeks.
Insurance Tip: Ensure buildings insurance is arranged from the date required by the contract or lender, as risk relating to the property often passes to the buyer at exchange.
On completion, funds move between conveyancers, keys are released, the seller’s mortgage is redeemed and you take possession. Your conveyancer then handles Stamp Duty/LTT and Land Registry registration.
Before marketing, know your mortgage balance, any early repayment charges, and estimate agent and legal fees so you understand your net proceeds and how they fund your onward purchase.
Get multiple valuations backed by comparable evidence. Choose an agent on local knowledge, marketing quality, communication and fee structure, not just the highest valuation.
Gather EPC, title docs, planning/building regs approvals, certificates, guarantees and leasehold info before marketing. Early preparation reduces delays and buyer concerns later. Start leasehold management pack requests early to avoid delays; firms like North and Broadway can chase managing agents on your behalf.
Don’t judge offers on price alone. Consider mortgage position, deposit, chain status, timing and evidence of funds to reduce the risk of a fall-through before exchange.
Respond quickly to enquiries, supply documents early and keep your conveyancer updated. Clear communication and realistic dates help keep the chain intact up to exchange.
Buyers should budget for deposit, legal fees, searches, survey, mortgage fees, tax, insurance and removals. Sellers should budget for agent commission, legal fees, leasehold packs, redemption charges and removals. MoneyHelper suggests legal costs around £2,000 and survey costs commonly ranging from £400 to £1,500 depending on the property.

• Over £1.5 million: 12%
Most fall-throughs happen before exchange due to mortgage issues, survey problems, title defects, leasehold concerns, search results, chain breaks or parties changing their mind.
• Gazumping: Occurs when a seller accepts a higher offer from another buyer before exchange.
• Gazundering: Occurs when a buyer reduces their offer shortly before exchange.
Both are possible because an accepted offer is not legally binding in England and Wales until exchange.
Use the FPLCT framework—Finance, Property, Legal, Chain, Timing—to score your deal green/amber/red before exchange. Any red means pause and understand the risk before committing legally.
| Area | Green | Amber | Red |
|---|---|---|---|
| Finance | Mortgage offer and funds are ready. | Offer or funds depend on an outstanding condition. | Mortgage is uncertain or insufficient. |
| Property | Survey and valuation are acceptable. | Further report or price discussion is needed. | Serious defects or a down-valuation remain unresolved. |
| Legal | Title, searches and enquiries are acceptable. | Material information is still awaited. | A title, lease or search issue is unacceptable or unresolved. |
| Chain | All linked transactions are progressing. | A transaction is delayed or weakly funded. | A key transaction has failed or cannot proceed. |
| Timing | Exchange and completion dates are achievable. | Dates depend on unresolved work. | The proposed dates cannot be met. |
