We returned four years ago ( still own a Cyprus property) and apart from a copy ( costing €40 ) of medical records which doesn't include X-rays

our possessions, two cats and passports....we just returned! We had kept our uk bank account, we eventually closed our Cyprus bank account ( we pay Cyprus bills direct online) as no longer needed...but we did it after two years...we'd still got our uk medical cards with numbers on...
The slog of returning was okay...took a couple of years to acclimatise ....enjoy the seasons again etc....it's all fairly straightforward....just re register with everything...i.e. Doctor, electoral roll, council tax, mobile phone, car tax, car insurance, personal tax....pensions...change your DL...let everyone you can think of know your new address....buy some warm clothes, boots and jeans...and enjoy Christmas in the UK...a nice time of the year for us...if you return pets reregister their microchip numbers with a uk microchip company with new address....
I too love the cosy feel inside in the winter in the UK, we are visiting Cyprus in January and we know the house inside will feel colder than our uk one.......but not for long!
