Context :

Aims : We present the discovery and characterisation of the exoplanets WASP-113b and WASP-114b by the WASP survey , SOPHIE and CORALIE .

Methods : The planetary nature of the systems was established by performing follow-up photometric and spectroscopic observations .
The follow-up data were combined with the WASP-photometry and analysed with an MCMC code to obtain system parameters .

Results : The host stars WASP-113 and WASP-114 are very similar .
They are both early G-type stars with an effective temperature of \sim 5900 K , [ Fe/H ] \sim 0.12 and \log g \sim 4.1 dex .
However , WASP-113 is older than WASP-114 .
Although the planetary companions have similar radii , WASP-114b is almost 4 times heavier than WASP-113b .
WASP-113b has a mass of 0.48 \mathrm { M } _ { Jup } and an orbital period of \sim 4.5 days ; WASP-114b has a mass of 1.77 \mathrm { M } _ { Jup } and an orbital period of \sim 1.5 days .
Both planets have inflated radii , in particular WASP-113 with a radius anomaly of \Re = 0.35 .
The high scale height of WASP-113b ( \sim 950 km ) makes it a good target for follow-up atmospheric observations .

Conclusions :
