£50 separates the two prices, and it reflects the building rather than the severity. But a flat is often the harder problem to finish, for a reason the price does not capture.
A flat is £190. A house is £240. The difference reflects the size and layout of the property, not how bad the infestation is.
The counterintuitive part: a flat is cheaper to treat but frequently harder to resolve, because rats move between units and your treatment covers only your property.
| Flat — £190 | House — £240 | |
|---|---|---|
| Rooms to work through | Fewer | More |
| Ground-floor perimeter | Limited or none | Full perimeter |
| Loft | Rarely | Usually |
| Garage or shed | Rare | Common |
| Garden | Rare | Usually |
| Underfloor voids | Sometimes | Often, in older properties |
Every one of those is somewhere a rat can live, travel through or enter from — which is why a house takes more work and costs more.

View Rat Control Harrow →This is the part the price difference does not tell you.
In a house, treating the property usually resolves the problem. In a block of flats, rats move through service voids, riser cupboards, shared drainage and the gaps around pipework between units. Your treatment can succeed completely and activity can return from a neighbouring property, or from the communal areas you have no access to.
A house at £240 is generally a job that ends. A flat at £190 sometimes needs a building-wide response, and no single flat treatment achieves that.
Worth knowing, because it explains a proportion of recurring rat problems that no amount of internal treatment fixes.
Rats use drainage systems, and a defective, cracked or disused drain run gives them a direct route into a building. In older terraces and converted flats sharing a drain run, that route is shared too.
Where we suspect drainage is the source, we will say so. Investigating and repairing it is a drainage contractor's job, not a pest controller's — and until it is done, treatment addresses the symptom.
If a property falls materially outside the normal scope of the service, you will hear that before any work is arranged.
| Property | Treatment | With proofing |
|---|---|---|
| Flat | £190 | £370 |
| House | £240 | £420 |
No. Rats range through a building, so treating properly means addressing the property rather than a room.
A house — £240.

A house has more rooms, more perimeter, usually a loft, often a garage and a garden — more property to work through.
Cheaper, but often harder to resolve — rats move between units through service voids and shared drainage.
Usually as a flat. Tell us the layout if it has its own street entrance.
No. The published prices are by property type, not severity.
We will tell you if we suspect it. Investigating and repairing drainage is a drainage contractor's job, and until it is done treatment addresses the symptom.
No. The same prices apply in every area we cover.
