Letting my home? Please advise!!!!!!

I was a first time buyer and own my property (3 bed duplex apartment). Bought it 11 months ago, 100% over 30 yrs (I'm 40 now). I can't say for sure if I'm in negative equity or not. Don't want to sell it. Also have a personal loan (18 k over 5 yrs, 9%) and c-card (7K on 0% switching balance around).
I don't have a perm. job here now. I work agency but the work is virtually guaranteed.Have very little savings. But credit record is clean.
I want to go abroad for a 1 yr, possibly more. I have a guaranteed job there.
I am aware of the 'claw-back' condition.
My main question is will my mortgage provider allow me to 'rent out'.
Will the terms/conditions of my mortgage change?
Can I ask them for a break/interest free repayment etc?
Should I tell them at all or just rent it?
What is BER?
Any advice GREATLY appreciated. Thanks

Dustyman,

Your mortgage shouldn't be affected.

As you know though you will be liable for the clawback on the stampduty if you rent it out fully. The alternative is to rent out only two bedrooms, keeping one as your own, and have an income under €11,000 on these rooms. This way it'll remain your principal private residence and you'll avoid the clawback and having to pay tax on the rental income.

BER is the building energy rating.

Some mortgages stipulate that the rate is dependent on the house remaining your PPR and oblige the mortgage holder to notify them if that changes (presumably with an attendant change in interest rate)
