Two Counties, Roughly Thirty Miles Apart, For One Genuine Reason

Willsway is based in Horsham, which means the fastest response times, the deepest job history, and a decade of knowing which streets still have their original pipework and which don't.

A short run south of Horsham, Southwater's expanded steadily since the 1980s around its country park and village centre, which means a housing stock that's younger and more uniform than Horsham's own.

Billingshurst's old village core along the A272 sits right next to new housing that's gone up around the station in the last fifteen years, and the two ends of town rarely share the same plumbing problems.

Built as one of the first New Towns after the war, a lot of Crawley's housing, Northgate, Furnace Green, Broadfield and the rest, went up within a fairly narrow window, which means a lot of it is now reaching the same age at roughly the same time.

Willsway is based in Horsham now, but Epsom is where a good number of the longest-standing customers still are: the reason the coverage map has two hubs instead of one, roughly thirty miles apart.

Leatherhead sits close to the River Mole, which has flooded parts of the town in living memory, and that history quietly shapes a genuinely practical question: where a boiler or utility room is sited, and what happens to it if water gets in.

Sat at the foot of Box Hill and the North Downs, Dorking's town centre carries a lot of listed and conservation-area housing, which means a straightforward boiler swap sometimes isn't quite as straightforward as it looks.

Reigate's larger detached and semi-detached houses, particularly on the newer estates toward the M25 corridor, tend to run bigger heating systems with more bathrooms than the West Sussex side of the coverage area.
