Cat Flap & Dog Flap Installation in Merseyside
Merseyside's homes include some of England's oldest terraced streets in Liverpool, large Victorian villas in Southport and on the Wirral, and post-war estates in Knowsley. The coastline from Southport round to the Wirral also brings its own considerations for doors that face the weather.
Homes in Merseyside at a glance
What the official figures mean for fitting a pet flap. Figures cover Knowsley, Liverpool, St Helens, Sefton and Wirral. These are area-wide figures, so your own home may be quite different. We'll always look at your actual door, glass or wall.
24.9%
of homes were built before 1919
England average: 20.3%
A higher share of pre-1919 homes than the English average. Older homes often have original timber doors and solid brick walls, which affect how a flap is fitted.
28.7%
of homes are terraced houses
England average: 23%
Terraced houses are more common than average, so rear kitchen and yard doors are typical places for a flap.
Older homes in Liverpool, Sefton and the Wirral
Around 31% of homes in Liverpool and 27–28% in Sefton and Wirral were built before 1919, but only about 3% in Knowsley, where most housing is post-war. In older homes, solid brick walls are common, and original panelled timber doors may be too thin in places for a flap without a reinforcing frame. In post-war and modern homes, cavity walls and uPVC doors are more usual.
Coastal homes
Homes along the Sefton coast and the north Wirral are exposed to strong winds off the Irish Sea. If a flap faces the prevailing wind, a model with a strong magnetic closure and brush seals helps stop it blowing open and letting draughts in.

Questions from homeowners in Merseyside
My front door is an original Victorian door. Can it take a flap?
Often, yes, but thin panels may need a reinforcing frame. If the door is a feature you want to keep, a back door, wall or glass installation might be a better choice.
Will a cat flap keep the wind out on the coast?
A good-quality flap with a magnetic closure and brush seals does a reasonable job. On very exposed doors, a sheltered door or a wall position away from the wind can be better.
Who handles planning in Merseyside?
Each of the five boroughs is its own planning authority. If your home is listed or in a conservation area, check with your council before altering original doors or walls.
