The seller has accepted your offer. In England and Wales, this is the point GOV.UK places the full mortgage application—not the moment a decision in principle automatically becomes money available for completion. The work now involves the lender, your conveyancer and, if you commission a survey, your surveyor. Knowing which job belongs to whom makes the next stage easier to organise.
Start the full application after the offer is accepted
A decision in principle is a written estimate of what you might borrow. It can help set a viewing budget, but it does not replace the full application. You may apply to the lender that supplied it or choose another; the earlier estimate does not commit you to that provider.
Affordability still depends on your finances, including income, regular outgoings and existing credit commitments. Keep your own spending plan alongside the lender's indicative amount: the maximum borrowing figure is not a target you need to reach. Repairs, improvements and applicable leasehold charges can add costs beyond the mortgage payment.
Separate the conveyancer's work from the lender's valuation
Your conveyancer carries out legal checks and works to ensure that the property meets the lender's requirements. The lender also arranges a mortgage valuation. These tasks concern different aspects of the purchase; an accepted bid does not mean that either has already been completed.
For your own progress record, keep application status, legal questions and the valuation as separate entries. Record who is handling each item and what information is still needed. This is a practical way to coordinate the purchase, not an additional legal requirement or a guarantee of lender approval.
Decide when to commission an independent survey
A mortgage valuation and an independent survey are different. GOV.UK notes that some buyers arrange a survey soon after an offer is accepted, while others wait for the lender's valuation. Treating the valuation as though it answers every question about the property's condition would miss that distinction.
If you commission a survey, read the report rather than relying on its existence alone. Ask the surveyor to explain the seriousness of identified issues and possible remedies. Use that explanation when considering any repair work and the money it may require; do not assume that the lender's valuation has already resolved those questions.
Bring new-build exchange deadlines into the same plan
GOV.UK notes that many developers ask buyers to exchange contracts and pay a deposit soon after reserving a new-build home. Let the lender and legal representative know the proposed deadline and establish whether they can meet it. The guidance also flags possible additional charges, including estate facility charges.
Before the next commitment, put the developer's deadline beside the lender's outstanding steps and the conveyancer's unresolved questions. That gives you a specific coordination task, rather than a general instruction to wait for approval. Any full mortgage offer should be read on its own terms: confirm the actual conditions in the lender's documents and seek appropriate professional help where needed.
