The average house cost £211,625 in March, down 0.2 per cent month-on-month but up 2.1 per cent year-on-year.
In the three months to the end of March, Northern Ireland saw house prices rise from 2 per cent in Q1 2017 to 7.9 per cent.
Wales also saw a pick-up in annual house price growth, from 3.3 to 6.1 per cent.
The West Midlands saw the strongest English growth in the first quarter, with prices up 4.9 per cent annually.
At the end of Q1 London house prices had fallen 1 per cent.
Nationwide chief economist Robert Gardner says: “On the surface, the relatively subdued pace of house price growth appears at odds with recent healthy rates of
employment growth, a modest pick-up in wage growth and historically low borrowing costs.
“However, consumer confidence has remained subdued, due to the ongoing
squeeze on household finances as wage growth continues to lag behind increases in the cost of living.
“Looking ahead, much will depend on how broader economic conditions evolve, especially in the labour market, but also with respect to interest rates.”
