The Chelsea said it hoped it would ease some of the financial concerns for borrowers at a time when wallets could be stretched.
Jemma Smith, product manager at the Chelsea, said: “We understand buying a new home can be extremely stressful – not to say expensive.
“We hope that by offering a free valuation and assistance with legal fees we can help to relieve some of this financial pressure.
"We can also take away a little bit of the stress and give our customers one less thing to worry about.”
In addition to mortgages for new purchasers, a free valuation and legal fee assistance is also available to remortgaging customers.
Smith said: “Homeowners wishing to switch lenders may be deterred by the associated costs of remortgaging. By offering these incentives we aim to remove this obstacle for them.”
