Investec Private Bank has reduced the rates in its higher loan-to-value range for fixed and tracker mortgages by up to 0.5 percentage points.
The lender has made the changes across its 80 to 85 per cent lending bracket, on three, four and five-year fixed rates.
In its owner-occupier range at 85 per cent loan-to-value, a five-year fixed rate has been reduced from 3.09 per cent to 2.89 per cent and a four-year fixed rate from 2.99 per cent to 2.84 per cent.
Peter Izard, business development manager at Investec Private Bank, said the lender was focussed on adapting and changing with the market.
He said: "We believe that by updating our mortgage offering, we are one step closer to helping brokers work with their clients to achieve their goals and ambitions.
"We are pleased to announce this reduction in both variable and fixed rates and hope it will enable our clients to have greater choice and flexibility."
Daniel Bailey, principal at Middleton Finance, said a number of lenders are cutting rates as the end of year approaches.
He said: "The remortgage market is particularly busy as millions of borrowers' mortgage deals are coming to an end in the last quarter of this year.
"Most of the rate cuts do tend to be for the lower loan to value mortgages. It is positive news borrowers with smaller amounts of equity or deposits can benefit from the cuts Investec are implementing."
Daniel White, managing director at White Financial Services, said he has seen some rate cuts over the last few weeks which may coincide with the run up to the end of the year.
He said: "Lenders may well be having one last push to try and take some last minute business to really end the year well.
"In addition, we’ve also seen some service standards fall behind on some key lenders so it may well be the perfect opportunity for other lenders to step in, price competitively and take some business away from some of the market leaders."
