The Planning Inspectorate decided 45 enforcement appeals against Havering in the year to March 2026, making it the third-busiest London borough for enforcement after Brent and Barnet. Around 29% of those appeals were quashed or granted permission — a success rate well above the English average. The council’s enforcement team receives more than 800 complaints a year and has shown a willingness to follow through with prosecution and direct action where they think it appropriate.
What makes Havering a little different to other London boroughs is that more than half of the borough sits within the Metropolitan Green Belt. The outer parts — Upminster, Cranham, Harold Hill, Noak Hill — are open countryside. This has an effect on the enforcement caseload in ways that don’t apply elsewhere in London.
Two distinct enforcement caseloads in parallel
Havering’s enforcement team runs deal with two different types of work in parallel.
There is the standard outer-London suburban enforcement work — unauthorised extensions, HMO conversions, outbuildings used as separate dwellings and breaches of planning conditions on smaller residential developments.
This accounts for most their householder caseload, concentrated in the dense Victorian and inter-war suburbs of Romford, Hornchurch, Rainham and Elm Park. Last month alone the council issued 7 enforcement notices, including against unauthorised HMOs at 3-6 Far Way in Hornchurch and against a car wash and vehicle repair site at 84-90 Ardleigh Green Road.
The second type of work they do is green belt enforcement – the council has been notably active in recent years against unauthorised caravan and traveller sites, equestrian developments and works relating to agricultural buildings. Enforcement and stop notices have been served recently at sites including Church Road in Noak Hill, the Gravel Pit at Gerpins Lane in Upminster and near Paige’s Wood in Upminster.
Most London boroughs deal almost exclusively with urban enforcement. Havering does both urban and rural, and it has built the enforcement experience to pursue both types of case effectively. A planning consultant acting in Havering needs to be comfortable in both worlds — the SPD-driven detail of a suburban first floor rear extension dispute, and the much harder policy framework of a green belt case where the underlying presumption is against the development in principle.
How enforcement cases usually start
As with most councils, Havering’s officers do not go looking for breaches. The team responds to complaints from neighbours, councillors, or in green belt cases, from bodies like Forestry England and local landowners. They receive a surprisingly large number of complaints — more than 800 a year — and the council has been explicit that it has to prioritise. The cases that make it through to formal enforcement action tend to be those where there is clear harm, the breach is most flagrant or there is some political pressure.
The first contact is usually a site visit, an informal letter or a Planning Contravention Notice. A PCN is a formal legal document requiring information within 21 days, and the answers given often determine whether further action follows. Where the council decides that a breach has occurred and that it is expedient to act, a formal enforcement notice usually follows. From that point the appeal deadline is 28 days, and missing it removes the right of appeal permanently.
In green belt cases the council often moves quite quickly. Where it judges that significant harm is being caused — earthworks underway, caravans being moved onto a site, hardstanding being laid — a temporary stop notice can be served almost immediately, halting works while the enforcement position is worked out. This is much faster than the standard suburban enforcement timetable and it catches many landowners off guard.
Appeals against Havering notices: two recent cases
According to government statistics, about 29% of enforcement appeals in Havering are successful. However, this success rate conceals significant variation depending on the type of case and the strategy adopted. Two recent cases of ours show the range of outcomes that are achievable when the right approach is taken.
27 Wigton Road, Romford was a clean ground (a) success. Our client had built a first-floor rear extension to his semi-detached house without planning permission. The council served an enforcement notice requiring its demolition, alleging that the extension was “intrusive and unneighbourly” in relation to the adjoining neighbour at number 25.
Our case was based on a careful reading of the council’s own Residential Extensions and Alterations Supplementary Planning Document. The SPD sets out three central recommendations for two storey rear extensions to semi-detached properties: no more than 3 metres deep, set in at least 2 metres from the boundary, and finished with a hipped roof. The extension at 27 Wigton Road complied with all three. It was also located to the north of the adjoining neighbour — a point that matters because the SPD itself states that the recommendations can be relaxed where an extension is to the north of the property next door, removing the most common amenity objection.
The inspector accepted the argument in full. He concluded that the extension was of an acceptable design, size and scale, that the property’s unusually large garden meant the extension did not appear dominant, and that there was no harm to the living conditions of either the adjoining neighbour or the more distant neighbours on Chudleigh Road. The enforcement notice was quashed and planning permission was granted on the deemed application. The full case study is here.
Carter Drive, Romford was a different kind of challenge altogether — and a useful example of how an apparently unwinnable enforcement case can sometimes be reshaped through strategy.
Our client had built two storey side and rear extensions, a single storey front extension, a loft extension with a rear dormer, and a boundary wall and fence exceeding the one-metre limit on the front boundary. An earlier planning appeal had already been dismissed, so we knew the extensions in their built form could not be retained. The council had served three enforcement notices demanding that the extensions be demolished in full, a gas protection condition on an earlier permission be complied with, and the extensions then rebuilt to that earlier permission. The compliance period was three months.
The strategic question was not whether we could save the extensions — that was not realistic — but whether we could find a route that allowed them to be altered rather than demolished. A previous permission for two storey side and rear extensions at the property was still extant. If we could discharge the gas protection condition through a separate application, the as-built extensions could in principle be altered to bring them within the scope of that existing permission, achieving the council’s enforcement objective without the much more drastic remedy of demolition and rebuild.
We submitted a separate application to discharge the condition, which the council approved in January 2025. The act of approving the discharge confirmed, by implication, that the previous permission remained extant. We then appealed the enforcement notices on grounds (b), (f) and (g), arguing among other things that the council’s required steps went beyond what was necessary to remedy the breach and that the proper remedy was alteration to match the existing permission, not demolition.
The inspector accepted the substance of the argument. The required steps were varied so that the requirement was simply to “remedy the breach by making the development comply with the terms” of the previous permission. The compliance period was extended from three months to nine. The council’s original demolition-and-rebuild requirement was set aside. The full case study, with the strategic reasoning explained, is here.
What these cases show
The two cases sit at different ends of the enforcement appeal spectrum, but the underlying lesson is the same. The council’s enforcement notice sets a position, but does not set the only possible outcome.
In the Wigton Road case, the council’s position was that the extension had to come down. A careful policy-led case showed that the notice was not supported by any specific harm identified within the council’s own guidance, and the notice was quashed.
In the Carter Drive case, the council’s position was that the extensions had to be demolished and rebuilt. Strategic use of parallel applications, combined with a targeted ground (f) argument, reshaped the position so that the extensions could be altered to match an existing permission instead. The council got its enforcement outcome. Our client kept most of what he had built.
Across the full range of Havering enforcement cases — householder extensions in Hornchurch and Romford, HMO conversions, outbuildings used as separate dwellings, green belt encroachments in Upminster and Noak Hill — the same principle applies. The council has a position. That position can almost always be examined, tested, and in many cases changed.
Three things to do if you have received a Havering enforcement notice
Act quickly. The 28-day appeal deadline is strict. Once it expires, the right of appeal is gone permanently. Havering’s enforcement team is active and willing to follow non-compliance through to prosecution and direct action, so delay rarely improves the outcome. In green belt cases in particular, the council often moves within days, and temporary stop notices can be served almost immediately.
Never ignore an enforcement notice. It will not go away. Once the compliance period expires, failure to comply is a criminal offence under section 179 of the Town and Country Planning Act 1990. The council can prosecute, seek substantial fines, and in some cases take direct action — sending in contractors to carry out the works themselves and recovering the costs through the courts.
Take strategic advice early. Enforcement is the most technical corner of the planning system, and the strategic choices have lasting consequences. The right route is not always the obvious one. As the Carter Drive case shows, an enforcement problem that looks unwinnable in its obvious form can sometimes be reshaped into a manageable one by working multiple workstreams in parallel.
