Everything appears to be moving fast for you. I don't expect our surveys to be complete before next week. Been having fun chasing up the gas safe registration for our boiler. It was installed in 2010, but wasn't registered by the engineer....He has now done it.
Mine was installed before I moved in around 2007 so I don't have any certificates for the boiler or electrics (house was built in 1981). The place we are moving to is oil fired and built in the 1930s so none needed there!
The plan is for it to move fairly fast, the buyers are buy-to-let purchasers and we are buying from a old lady who has moved to a nursing home so there's no chain really. We put our current house on the market 29th October. Our buyers already had a mortgage agreed and we used a mortgage company we knew would be fast and hassle free, they also happened to offer the best rate for our chosen product. I tend to ring the solicitor once or twice a week for a status update too, keeps us fresh in their mind, along with going down in person to sign anything required.
