Finchley & Golders Green apart from a couple of minuscule ward realignments.
Ealing N subject to the same caveat.
If you're going to be strict about not allowing ward realignments then you need to remove Hayes & Harlington from the list.
Torbay.

You've missed Pete Whitehead's Eastern list: Stevenage, NE Herts, Epping Forest, Ipswich and Great Yarmouth. However, the BCE's mapping suggests there is a small area (close to the tripoint of the two constituencies with Hitchin) transferred from NE Herts to Stevenage. I think it reflects this local government boundary re-alignment. I'm not sure whether it should count, as the area appears from mapping to contain no buildings, but there is actually a very small area (on the southern boundary of East Ecclesfield ward) transferred from Penistone & Stocksbridge to Sheffield Brightside & Hillsborough. So perhaps P & S should have an asterisk or something. Electoral Calculus lists Gillingham & Rainham as unchanged, and the BCE's mapping seems to confirm this. Leeds North East is in the same category as Shipley and Keighley (& Ilkley). |

Theya re not minuscule. If we were counting seats with that magnitude of change there would be many others (eg Brentwood & Ongar sees probably a smaller change in terms of the number of electors) |

What about Erewash?

I missed Erewash. It isn't really 'my' definition. Either a seat is unchanged or it isn't. In as much as there is any grey area it is such as in the seat which kicked the discussion off - Hayes & Harlington where the boundary changes really are minuscule and might only involve the transfer of one or two properties and hardly any voters. That certainly doesn't apply in Finchley & Golders Green where it looks like something like 300 voters are moving in or out. |

I think you can usefully distinguish between unchanged and unchanged except for ward re-alignment but it's probably worth recording both.

Coventry NW.
And in the 'tiny change' category I'd add Bournemouth E, SE Cornwall, Rugby.

I think you can usefully distinguish between unchanged and unchanged except for ward re-alignment but it's probably worth recording both. Ward realignment can mean movement of thousands of voters in urban seats. However a secondary list of seats with less than 1000 voters moving (virtually unchanged) would be useful. I’d do it myself, but I’ve still got loads of profiles to update with boundary info first. |

The following list is also based on Electoral Calculus's data, and lists constituencies which contain at least 98% of their main predecessor and the sum of the percentages coming from other seats is at most 2%. Names are those for the new seats where they have changed; I believe there are two on this list (Bedworth & North Warwickshire and Hove & Portslade) where the name is the only change.
Not all of these are just "re-alignment to new ward boundaries"; e.g. the change to the two Bradford constituencies on the list is that a ward has been split, with a single polling district being included in one rather than the other. And some constituencies have "re-alignment to new ward boundaries" which goes above the threshold used here, e.g. Sheffield Hallam.
Berwickshire, Roxburgh & Selkirk
Warrington North
Sheffield Brightside & Hillsborough
Bradford East
Bradford South
Keighley & Ilkley
Hereford & South Herefordshire
North Herefordshire
Telford
Bedworth & North Warwickshire
Rugby
Amber Valley
Bolsover
North East Derbyshire
Rushcliffe
Bedford
Peterborough
Brentwood & Ongar
Welwyn Hatfield
North Norfolk
South East Cornwall
Newton Abbot
Torbay
Bournemouth East
Finchley & Golders Green
Ealing North
Romford
Carshalton & Wallington
Sutton & Cheam
Hove & Portslade
Dover & Deal

Sub-question: which local authorities have no changes to constituencies within their borders?
Trafford is one, with 2-and-a-bit constituencies unchanged. (No doubt there are some single-constituency ones among the islands and some smaller district authorities.)
