Planning enforcement in Brent: inside England’s most active council

Brent is the country’s most active enforcement authority

If you have received an enforcement notice from Brent, the first thing to understand is that Brent is not a typical authority. It describes itself as “the leading local authority for planning enforcement in the entire country”, and serves more enforcement notices each than almost any other council in England.

It also prosecutes more landlords, makes more aggressive use of the Proceeds of Crime Act and sends in the diggers to demolish unlawful buildings more often. None of that means a notice cannot be challenged – we appeal them regularly and win – but it does mean an enforcement case in Brent has to be taken very seriously.

It serves more enforcement notices each year than almost any other

Brent has served around 700 enforcement notices in the last five years and is consistently in the top three local planning authorities nationally. The council is proud of its record on enforcement, stating that:

“Brent has been at the forefront of planning enforcement activity for over a decade, with a clear emphasis on taking action to achieve outcomes when necessary.”

Unlike lots of councils, Brent is active is pursuing cases where an enforcement notice has been served but the landowner has not complied with it. It takes legal action against 5 to 10 landlords or developers each year for failing to comply with enforcement notices. It secures three to six confiscation orders annually under the Proceeds of Crime Act, recovering the unlawful profits from breaches of planning control. It takes direct action — sending its own contractors onto site to carry out the works required by a notice when the owner refuses — around a dozen times a year.

As the council puts it, “no other authority combines this with the level of subsequent prosecution and direct action that is undertaken by the council.”

The firm-but-fair policy

Brent’s adopted Planning Enforcement Policy describes the Council’s approach as “firm but fair”. It means the council will pursue serious breaches without hesitation, but it also means enforcement is reserved for cases of genuine harm. The council takes action where it is ‘expedient’: there has to be harm to public amenity, safety or the environment, and the development has to be one for which planning permission would be unlikely to be granted.

The fact that you have built something without planning permission is not, in itself, an offence. The offence arises only when an enforcement notice has been served and the deadline for compliance has passed. Before that point, there is space — sometimes significant space — to resolve the issue through negotiation, a retrospective application, or a properly framed response to a Planning Contravention Notice.

How enforcement is resourced

The team is led by Tim Rolt, the council’s long-standing Planning Enforcement Manager, with around six and a half full-time officers behind him. Four of those posts are funded out of the council’s base budget; the remaining two and a half are funded directly out of Proceeds of Crime Act receipts, which by law must be ringfenced for the detection of planning enforcement crime and cannot be used as a substitute for the base budget. In practice, this means Brent has been able to keep more boots on the ground than most authorities by recycling the proceeds of its prosecutions back into the enforcement team.

Even so, the team is stretched. The council carries around 1,865 open cases at any one time — a combination of investigations and unresolved notices — and each enforcement officer is managing an average caseload of around 250 cases. That is consistent with the national picture: the Royal Town Planning Institute reported in 2022 that 89% of authorities are running with significant enforcement backlogs and 80% of enforcement officers say there are not enough of them to carry the workload. The point for anyone caught up in a Brent investigation is that the team has limited time per case and will move efficiently when it does move. Drift and delay on the recipient’s side rarely improves the outcome.

What gets enforced against in Brent

Brent’s enforcement work is shaped by its geography. The borough runs from the dense Victorian and Edwardian terraces of Kilburn, Harlesden, Willesden, Cricklewood and Kensal Rise in the south, through the post-war suburbs of Wembley, Sudbury and Kenton, to the high-density regeneration around Wembley Park in the north. Each of these areas has its own enforcement profile.

The most common breaches are unauthorised flat conversions and unauthorised HMOs, particularly in the older housing stock. A typical Brent case is a single-family house quietly subdivided into multiple self-contained units with no planning consent, often with substandard room sizes and inadequate amenity space — the issue the council describes as “rogue landlord” activity. Unauthorised outbuildings being used as separate dwellings (“beds in sheds”) are a long-running issue across the borough. Unauthorised industrial and commercial uses — particularly conversions of small commercial units into shisha lounges, car washes, places of worship, or unregulated workshops — feature heavily, and the council has historically run cross-agency operations targeting these.

Unauthorised rear and side extensions in the residential streets, especially where they exceed permitted development limits or have been built even though planning permission was refused for them, make up the bulk of the householder caseload. The council also makes regular use of section 215 notices against untidy land and neglected commercial frontages, particularly during town centre improvement programmes in Kilburn, Neasden, Harlesden and Wembley.

The Proceeds of Crime Act dimension

The most distinctive feature of enforcement in Brent is the Council’s willingness to pursue confiscation under the Proceeds of Crime Act 2002 once a prosecution has succeeded. This is rare nationally but much more common in Brent.

Where a landowner has been convicted of failing to comply with an enforcement notice, the council can apply to the Crown Court for a confiscation order requiring the defendant to pay over the financial benefit they obtained from the unlawful development. For a landlord who has converted a house into unauthorised flats, that benefit can be calculated as the entire rental income obtained from the unauthorised use over the years it ran.

In 2018, a joint Brent and Harrow prosecution against landlord Vispasp Sarkari resulted in a £1.5 million confiscation order from Harrow Crown Court, plus separate fines of £12,000 and full costs. Judge Wood described Mr Sarkari’s breaches as “a flagrant abuse of the Town and Country Planning legislation”. The council secured a restraint order preventing Mr Sarkari from disposing of his assets before the order was paid, with the power to force the sale of his properties if payment was not made.

That case shows the genuine financial risk that follows a failure to comply with a Brent enforcement notice. A landlord whose unauthorised conversion produces £30,000 a year in rent for five years is potentially exposed to a six-figure confiscation order on top of the underlying fine.

Appeal data

In the year to 31 March 2026, the Planning Inspectorate decided 75 enforcement appeals against Brent — the highest enforcement appeal volume of any London borough, and one of the highest in the country. Around 19% of those appeals were quashed or granted, broadly in line with the English average.

Appeals that try to argue retrospectively for permission under ground (a) on amenity grounds alone tend to struggle, because Brent’s policy framework against unauthorised flat conversions and HMOs is well-developed and inspectors have been broadly supportive of the Council’s reasoning. Where notices fall, they tend to fall on the technical grounds: that the alleged breach has not actually occurred, that the development is immune from enforcement under the four-year or ten-year rule (depending on when the breach occurred), that the notice is imprecise or defective, or that what it requires goes beyond what is necessary.

In one of our recent cases, the council had served an enforcement notice on a property in the borough alleging unauthorised works that, on the face of the notice, would have required substantial demolition. We identified that the notice had been drafted in terms that did not precisely match the development on site, and that the requirements went beyond what was necessary to remedy the alleged breach. The notice was quashed at appeal.

We have a long track record of successful enforcement appeals in Brent across the full range of breach types — unauthorised extensions, unauthorised flat conversions, retrospective permission applications, certificate of lawfulness cases, and notices quashed on technical grounds. Our dedicated Brent enforcement page collects the most recent examples, and they are worth looking at if you want a sense of the kinds of cases we handle and the outcomes we have achieved.

The national resourcing context — and what it means for Brent

Planning enforcement nationally is in difficulty. Real-terms spending on planning has fallen by 43% since 2009/10. The Royal Town Planning Institute reported in 2022 that the system was “falling apart” — 89% of authorities had enforcement backlogs, 80% had insufficient officers, and 73% had struggled to recruit. The number of enforcement notices issued in England has fallen materially over the last decade. In many local authorities, enforcement is now overwhelmingly reactive, dependent on complaints from the public to surface breaches at all.

Brent’s position is therefore unusual. Through a combination of POCA-funded posts, a long-standing enforcement manager with deep institutional knowledge, and a clear political will to pursue cases through to prosecution, the borough has bucked the national trend. It is not that Brent’s team is large — it is fractionally below the London average of 7.5 full-time officers — but the team has been protected, focused, and willing to follow cases to the end of the legal process. For someone on the receiving end, that means a much higher probability of a Brent investigation leading to a notice, a higher probability of a notice leading to prosecution, and a higher probability of prosecution leading to a confiscation order. The xouncil does not bluff.

Four things you must do if you have received an enforcement notice

Act quickly. Enforcement notices have strict statutory deadlines. The appeal has to be lodged before the notice takes effect — usually 28 days from the date of issue — and once that period expires the right of appeal is gone permanently. Even at the earlier stages, when a Planning Contravention Notice has been served or a planning enforcement officer has been in touch informally, every day matters. In Brent in particular, the team moves efficiently once it has decided to act.

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. In Brent, prosecution is routine, fines are substantial, and the Council will pursue confiscation under the Proceeds of Crime Act where the unauthorised development has generated rental income or other financial benefit. The Council also has and uses its direct action powers — it will send its own contractors onto site to carry out the works the notice requires, and then recover the costs from the owner.

Take professional advice early. Enforcement is the most technical and unforgiving corner of the planning system, and in a borough like Brent the stakes are particularly high. The procedural deadlines are tight, the legal tests for each ground of appeal are particular, and the strategic choices — whether to appeal at all, on which grounds, whether to submit a retrospective application instead, whether to try to negotiate compliance — have lasting consequences. We have had success in Brent persuading the Council to withdraw notices after we have submitted an appeal and the council has reviewed our case and evidence, but that only works when the right arguments are identified at the outset.

Treat it as a serious legal obligation. An enforcement notice is a binding legal instrument that runs with the land. It affects your ability to sell or mortgage the property, it creates criminal liability for non-compliance, and in Brent’s case it carries a realistic risk of large-scale financial exposure through POCA proceedings on top of the underlying fine and costs.
